AUTOMATIC TWO-STATION ADIABATIC BLANK CUT-OFF AND PART FORMING SYSTEM

Abstract: A system for automatically producing formed parts from feedstock using two successive adiabatic forming stations, a first station performing adiabatic cut-off of blanks from the feedstock, and the second station performing adiabatic shaping of the blanks into the formed parts. The first station operates cooperatively with a feedstock feeder assembly which feeds feedstock to the first station and also charges blanks produced at the first station into a transfer capsule of a transferer assembly. The first and second stations cooperatively operate with the blank transferer assembly which transfers in the transfer capsule blanks from the first to the second station. The second station includes means for positioning blanks relative to a shaping cavity before blanks are adiabatically shaped to conform to the shaping cavity and also means for ejecting formed parts from tooling that defines the shaping cavity. The system includes automation means that synchronizes and sequences subassembly operations.

Description: AUTOMATIC TWO-STATION ADIABATIC BLANK CUT-OFF AND PART FORMING SYSTEM Field of the Invention This invention relates to an automated, integrated, synchronized part forming system that incorporates two adiabatic processing stations which each have multiple operating stages whereby, progressively and successively, elongated feedstock is cut into blanks that are formed into parts. Background of the Invention High speed impact systems for metal and plastic working, such as, cut-off and forming or shaping, using the adiabatic ' -softening phenomenon, although the subject of research and development since World War II, have proven to be difficult to achieve, control and use for mass production. The energy utilized involves very high impact speeds and very short machine tool engagement times. In adiabatic forming, each part (or work piece) requires a certain amount of applied energy to be completely formed. That energy can be distributed and should never be provided by impact alone. In successful adiabatic forming, the energy delivered to a work piece is critical as no tooling can stand up to the magnitude of the shock waves created by full energy impacts. It was discovered that limited forming and tool engagement time reduced the opportunity for heat to transfer into surrounding tooling. When a work piece cannot conduct heat away at the rate at which it is generated, the work piece temperature increases in a pre-determined, plastically strained zone, causing the work piece material to soften and experience decreased flow stresses, resulting in reduced energy requirements to move the material. It was found that a successful adiabatic forming operation could be achieved based on a two-part sequence of impact and immediately succeeding power stroke (or force application) . In a work piece heated by impact, the heat pattern relates to the final form; some areas remain at ambient temperature while other areas may reach temperatures close to melting point. Such elevated temperatures minimize flow resistance and stresses, reduce tooling load and allow material flow into relatively small crevices. At this point, a power stroke immediately follows impact and completes a part forming operation with little resistance. Thereafter, the^ formed part is ejected. The adiabatic impact and power stroke part forming sequence and the part ejection from adjacent tooling are rapidly carried out . An impact press device 'capable of providing a suitable impact for adiabatic forming is disclosed in indell U.S. Patent No. 4,245,493. A tooling assembly that is suitable for use with such an impact press and that is adapted for the cut-off of elongated feedstock into blanks is disclosed in Lindell U.S. Patent No. 4,470,330. Adiabatically formed parts are desirable and even superior to parts produced by conventional forming processes because they can be rapidly produced, and are uniform and free from defects, such as burrs, work/strain hardening, pull-down and micro-cracks. For use in the mass production of parts, practical automatic adiabatic forming systems are desirable and needed, but the systems must also be reliable, operable at high piece throughput speeds, and require minimum manpower. An adiabatic part forming system that is capable of converting elongated starting stock into formed parts rapidly and in an automatic manner would be very useful . Such a system would require both an adiabatic processing station for the cut-off of elongated feedstock, ^ such as stock in the form of a bar, tube or coil, for example, into blanks, as well as an adiabatic processing station for forming of blanks into parts. Each station and the entire system would have to be capable of high throughput rates. Particularly when the stations are substantially independent, such a system would require a stock feeder, an interstage blank' .transferer, and sychronization means . The stock feeder would have to be integrated . with the first station stock cut-off device, and be adapted.both for feeding and positioning of elongated stock and also for the separation and advancing of blanks. The inter-station blank transferer would have to be integrated with both the first station and the second station, and be capable of receiving blanks from a first station location, of transporting blanks from the first station to the second station, and of depositing blanks at a second station location. The synchronization means for operating the system would not only have to control the operation of the respective multiple sequential operating stages of each station, but also have to integrate operations of the stock feeder and the interstage blank transferer with the operations of first station and the second station. Mere adaptations by those of ordinary skill in the art of prior art adiabatic impact devices for accomplishing adiabatic cutting or shaping of work pieces with high throughput rates may be possible, but such adaptations by themselves, even if achieved, would be inadequate without suitable peripheral equipment, such as a suitable stock feeder, a suitable inter- station blank transferer and suitable automation means. A combination of suitable components is needed to achieve an automatic, integrated, adiabatic forming system capable of operating at high throughput rates. Such a system has never previously existed so far as now known. Indeed., to create such a two-station adiabatic blank cut-off and part forming system, not only must significant, nonobvious advances in adiabatic cutting and shaping stations be achieved, but also the indicated coacting peripheral ' .required subassemblies must be invented because such subassemblies have riot previously existed. The present invention aims not only to achieve the components necessary for such a system, but also to achieve the combination of such components into such a system, thereby to satisfy the need for such an adiabatic forming system. To create the present system, substantial technological advances in the art have been necessary. Summary of the Invention This invention relates to an automated, integrated, synchronized part forming system that incorporates two adiabatic processing stations that operate sequentially relative to one another. First, an adiabatic blank cut-off station progressively and successively cuts elongated feedstock into identical blanks. Next, an adiabatic part forming station progressively and successively forms the blanks into identical parts. Each station has its own multiple, sequential, cyclical operating stages. The cut-off station cooperatively operates with a stock feeder subassembly. The cut-off station and the forming station cooperatively operate with an interstation blank transferer subassembly. The system includes synchronizing, sequencing and regulating automation means effective for all components. The invention also relates to component subassemblies that are incorporated into the system and make possible the practical operation of the inventive system which includes the respective adiabatic forming stations, the stock feeder subassembly, the interstation blank transferer subassembly and the automation means . The invention involves apparatus including the system itself, its component assemblies arid subassemblies, and various combinations thereof . The invention also involves methods, including the sequential adiabatic method of part formation progressing from starting feedstock through intermediate blank to formed part. The invention is not limited to the cut-off of one blank at a time from elongated feedstock. In a cutoff station two or more blanks can be concurrently cutoff. Also, the invention is not limited to the forming of one part at a time from a blank. In a forming station, a double forming die or cartridge arrangement can be employed. Two forming stations that are either successively operated relative to each other in part formation or that each receive blanks from a, cut-off station can be utilized. The first adiabatic station in which feedstock is cut-off into blanks can advantageously incorporate two separate, independently operating, but integrated and synchronously functioning, adiabatic cut-off. devices, each one of which is provided with an independent stock feeder subassembly. Similarly, the second adiabatic station in which blanks are successively formed into parts can advantageously incorporate two separate, independently operating, but integrated and synchronously functioning, adiabatic blank forming devices, each one of which is provided with a separate blank transferer subassembly. Accordingly, it is an object of the present invention to provide an automated integrated, progressively operating, synchronized, two station adiabatic forming system, one station of which cuts feedstock into blanks, the other station of which shapes blanks into formed parts; Another object is to provide such an automated system which operates at high work piece throughput speeds yet which operates with precision so that the system produces consistent formed parts that are free from imperfections and defects.

Another object is to provide improved tooling adapted for use in a system for accomplishing adiabatic stock cut-off and adiabatic blank forming. Another object is to provide an automatic system for blank cut-off and part forming which utilizes a starting feedstock having any shape or configuration including feedstock that is solid or tubular in cross- section. Another object is to provide an improved stock feeder subassembly for an adiabatic processing device, such as a stock cut-off device. Another object is to provide, in a stock feeder subassembly of the type indicated, the capability of carrying out step-wise successive cycles involving the advancing of an elongated feedstock into an adiabatic cut-off apparatus, the positioning and clamping of the feedstock during feedstock cut-off and blank formation, the separating of a cut-off blank from the cut-off apparatus, and, especially, the loading of the separated blank into a blank transferer subassembly, ' the feedstock advancing and the blank separating and loading being carried out successively iri coordination with operations of an associated adiabatic cut-off device. Another object is to provide an improved blank transferer subassembly that is adapted for moving a work piece from one adiabatic tooling device to another, such as from a stock cut-off device to a work piece shaping device . Another object is to provide, in a blank transferer subassembly of the type indicated, the function of carrying out successive cycles involving picking up a . work piece at one location at one adiabatic tooling device, transporting the work piece, and discharging the work piece at a second location at a second adiabatic tooling device, the picking up and the discharging being accomplished while maintaining the work piece in a predetermined spatial orientation. Another object is to provide automation means for an adiabatic forming system that is adapted for high part throughput operating rates, that accomplishes part formation from feedstock proceeding through blank formation to formed product part, and that incorporates two successive adiabatic processing stations that each has multiple operating, steps. Another object is to provide, in an automation means of the type indicated, the capacity to regulate and control sequential and synchronized functioning 'of a series of associated peripheral assemblies that are associated with the adiabatic stations, the peripheral stations including a stock feeder means, a blank removal means, a blank transferer means, and a formed part ejection means.

Detailed Description Referring -to Fig. 1A, a flow diagram illustrating the sequence for automatic part formation from feedstock is seen that illustrates one preferred sequence of process operating steps for practicing the present invention. In a first step, an elongated feedstock is fed incrementally to, and positioned in, an adiabatic cut-off zone. In a second step, in the adiabatic cut-off zone, a prechosen increment of the feedstock at the feedstock forward end is adiabatically cut-off by an impact applied along a transverse shear plane relative to the elongated feedstock, thereby to produce a blank in less than about one millisecond. In a third step, the blank is advanced into a transfer capsule. In -a fourth step the capsule holding the blank is transferred from the adiabatic cut-off zone to an adiabatic forming zone. In a fifth step, the blank is located at a forming cavity in the adiabatic forming zone. In a sixth step, forming cartridges are closed in the adiabatic forming zone. In a seventh step, the blank is adiabatically formed to conform to the cavity by a sequentially applied combination of impact immediately followed by an application of a power stroke, thereby to produce a completely formed part in milliseconds. In an eighth step, the formed part is ejected. Referring to Fig. IB, a flow diagram is shown illustrating a preferred sequence of mechanized operations that are employed in accordance with the invention to carry out the process step sequence of Fig. 1A. First, feedstock is fed, positioned, and held in the adiabatic cut-off zone. Second, in that zone, a ram is fired, energy is applied, and a pair, of initially aligned cut-off dies is disaligned, thereby to sever adiabatically a blank from the feedstock forward end. Third, the dies are realigned. Fourth, the feedstock is overadvanced, thereby to move the cut-off blank into a transfer capsule. Fifth, the capsule is transferred to an adiabatic forming zone. Sixth, in the forming zone, the blank is moved from the transfer capsule and transferred into a forming position, and the capsule is separated. Seventh, forming cartridges are engaged to define generally a forming adjacent portions of the blank. Eighth, an energy-transfer hammer is ' advanced and abutted against the blank adjacent the forming cavity. Ninth, a ram is fired against the hammer, the hammer is suddenly pushed against the blank, and the blank is partially formed. Tenth, power is applied against the ram, and, resultingly, the blank is formed into conforming relationship with the forming cavity, thereby producing a formed part. Eleventh, the forming cartridges are separated. Twelfth, the formed part is ejected from the forming zone. The operations of Fig. 1A and Fig. IB are practiced in the present invention. An embodiment 99 of the inventive two station adiabatic forming systesm, which utilizes and performs such operations, and which includes the incorporated subassemblies, is illustrated in Figs. 3 - 48. (a) System 99 Operation and Subassembly Cycles of Operation The present section of the specifi'cation describes system 99 operation. Structural details are described in subsequent sections. Referring to Figs. 2A, 2.B and 2C, there is seen the system 99 embodiment which comprises adiabatic cut-off assembly 100/101, forming assembly 150, transferor assembly 148, and control station 130.

As shown in Fig. 3, the cut-off assembly combination 100/101 is at one operating position or configuration that occurs in a complete cycle of automatic operation of system 99. In Fig. 3, an elongated feedstock 103, such as a metal bar or the like, is being held by the stock feeder assembly 101 in position for a predetermined feedstock 103 forward end portion to be cut-off by the impact press assembly 100. The impact press assembly 100, the stock feeder assembly 101, and the feedstock 103, when present, are supported by a frame 104. The stock feeder assembly 101 incorporates three grippers, identified as stationary gripper 106, first movable gripper 107, and second movable gripper 108. Each of the .grippers 106, 107 and 108 is adapted to ' clamp and hold an adjacent portion of the elongated feedstock 103. In the combination 100/101 assembly operating position shown in Fig. 3, the first movable gripper 107 clamps the feedstock 103. The first movable gripper 107 has been advanced to a full forward position, and, when in this position, the gripper 107 has advanced the feedstock 103 to a predetermined position for cut-off by apparatus 100. Fig. 4 shows mainly details of the adiabatic impact press assembly 100, the assembly 100 being in the operative configuration shown in Fig. 3. A further description of the assembly 100 is provided in the following section. The feedstock 103 forward end portion extends into or through the bores 112 and 113 of the die blocks 109 and 111 to the desired predetermined extent needed to place the plane of cutting desired for feedstock 103 into aligned relationship with the plane 115 defined between the die blocks 109 and 111. In the assembly 100, just before ram 116 impact on energy- transferring hammer 114 occurs, a cycle of operation of apparatus 100 can be considered to commence. In the stock feeder assembly 101, a change in feedstock gripping occurs just before ram 116 impact on hammer 114 occurs. The movable gripper 107 of the feeder assembly 101 releases the feedstock 103, and the feedstock 103 is gripped by the stationary gripper 106, there being a short dwell time interval during which the feedstock 103 is held by both such grippers 106 and 107 to avoid any shift in the position of feedstock 103. All clamping and releasing is performed during the dwell times of the movable grippers 107 and 108. After this change in feedstock 103 gripping has occurred, the grippers 106, 107, and 108 appear as shown in Fig. 7, and this configuration is maintained during blank 119 cut-off. The operating configuration shown in Fig. 7 corresponds to the configuration shown in Fig. 6. After blank 119 cut off, the stationary die block 109 and the movable die block 111 have their bores 112 and 113 realigned. In Fig. 7, the second movable gripper 108 . has been moved and is located substantially at its rearward-most location along the path of feedstock 103 travel. Immediately after the stationary gripper 106 clamps the feedstock 103, the ram 116 is fired (released) . After the ram 116 impacts against the hammer 114, the impact is transferred to the movable die block 111, The result is that the movable die block 111 is translated and the feedstock 103 is severed along the parting plane 115 defined by the adjacent faces of the die blocks 109 and 111. The resulting cut-off forward end portion of the feedstock is a blank 119. During the severing, the feedstock 103 has room to move transversely in the channels of the spacer block 117 and the guide bushing 118. In the impact press assembly 100, before the severing, the positive die return subassembly 121 is retracted by springs, as below described. The total time period transpiring between impact and blank 119 severing is less than about one millisecond. After the blank 119 severing from the feedstock 103, the positive die return subassembly 121 pushes the movable die block 111 back into bore alignment with the stationary die block 109, as illustrated in Figs. 6 and 7. The ram 116 of the adiabatic cut-off assembly 100 is retracted by the ram operating mechanism 120, thereby effectively completing one full cycle of operation of the assembly 100. In stock feeder assembly 101, after blank 119 cutoff, the stationary gripper 106 releases the feedstock 103, and the second movable gripper 108 clamps the feedstock 103, as shown in Fig. 8. The first movable gripper 107 translates backwards to its predetermined rearward-most position. The second movable gripper 108, while clamping the feedstock 103, now advances the feedstock 103 forwards along the feedstock pathway to a predetermined extent that is sufficient to cause the forward end of the feedstock to push the blank 119 completely out of the stationary die block 109 and also completely into a predetermined transfer position that is located in a transfer capsule 146, as shown in the assembly 100/101 configuration illustratively shown in Fig. 9. Thereafter, the second movable gripper 108 retracts the so-clamped feedstock 103 backwards along the feedstock pathway to a predetermined extent that is sufficient to place the forward end of the feedstock at the parting plane 155, as shown in Fig. 10. In this apparatus configuration, the second movable gripper 108 is either at or near its point of rearward-most travel, depending upon apparatus adjustments. Next, the first movable gripper 107 clamps the feedstock 103 and the second movable gripper 108 releases the feedstock 103, as illustrated in Fig. 11. The first movable gripper 107 now advances the feedstock 103 to the extent necessary to place the feedstock 103, and the assembly 100 and assembly 101, in the respective operating positions shown in Fig. 3, thereby completing one cycle of operation by the stock feeder assembly 101. ω t to μ> μ> o LΠ o LΠ o Lπ rt li 0 H Ω μ 1 f Ω rt μ- rt SD fu rt t_l.

Ω H rt Φ φ the transferer assembly 148 and moves the transfer capsule 146 from the position 145 to a prechosen position 155 at the adiabatic forming apparatus 150, as illustrated in Fig. 23. When the transfer arm 147 is in the position 155, the transfer capsule 146 is located at the adiabatic forming apparatus 150 so that the blank 119 in the transfer capsule 146 is transferable from the transfer capsule 146 into the adiabatic forming apparatus 150. After the transfer arm 147 has moved to position 155, the configurational interrelationship between the transferer assembly 148, including the transfer arm 147 and the transfer capsule 146 with the blank 119, and the adiabatic forming apparatus 150, is as illustrated in Fig. 24. The configuration of the adiabatic forming apparatus 150, at this point in its cycle of operation, is illustrated also- in Fig. 24.. The structure of the adiabatic forming apparatus 150 is further described below. When the transfer arm 147 is in the position 155, the capsule 146 is in its desired position at the adiabatic forming apparatus 150, as shown, for example, in Figs. 24 and 25. The transfer capsule 146 incorporates a pneumatic or hydraulic cylinder arrangement that includes a piston 168 which is reciprocatably movable in a cylinder chamber 169a and b that is a diametrically enlarged rear region defined in a longitudinally extending cavity 166 that extends axially through the transfer capsule 146. The piston 168 is axially connected to a shaft 167. Responsive to fluidic (preferably pneumatic, more preferably compressed air) input through channel 171 into chamber 169b and applied against the rearward face of th 168. As a consequence, the piston 168 and the shaft 167 are advanced in chamber 166 of capsule 146. The forward end of the shaft 167, which abuts against the blank 119, pushes against and causes the blank 119 to be moved forwardly and slidably completely out of the transfer capsule 146 and into the forward end portion of the adjacent axial channel 173 of a the stationary forming cartridge 154 of the forming assembly 150, as illustrated, for example, in Figs. 26 and 27. Preferably an end portion of the blank 119 protrudes from the channel 173, as shown, for example, in Figs. 26 and 27.-. After advancing the blank 119 into the channel 173 of the cartridge 173, the piston 167 and the shaft 167 are fully retracted in the transfer capsule 146, as illustrated, for example, in Figs. 28 and 29, responsive to fluidic pressure input through channel 172. into chamber 169a and applied against the exposed forward face of the piston 168. Thereafter, the transfer arm 147 pivots at shaft 151 and returns with the now empty transfer capsule 146 from the position 155 back to the position 145 at the adiabatic cut-off apparatus 100/101, as shown, for example,- in Fig. 22, thereby completing a cycle of operation of the transferer assembly 148. After the transfer capsule 146 has left position 155 in the adiabatic forming apparatus 150, the movable second forming cartridge 156 of the forming assembly 150 is advanced axially towards the stationary first cartridge 154. The forming cartridge 156 is set axially into the head of an extensible and retractable piston 157. To achieve this advance of cartridge 156, the piston 157 is slidably translated, forwardly, as illustrated in Figs. 30 and 31, an arrow in Fig. 31 indicating the direction of movement of piston 157, until the forward end of the cartridge 156 is abuttingly engaged with the forward end of the cartridge 154, as illustrated in Fig. 32. After the cartridges 154 and 156 become engaged, they are effectively locked together. The moving mechanism employed is below described. When the cartridges 154 and 156 are engaged, the walls of a forming cavity 160 are generally defined by the cartridges 154 and 156 except for the wall areas defined by the adjacent forward end portions of an ejection pin 177, and also by the adjacent portions of the blank 119, the latter being in opposed relationship to the former. The arrangement is such that . initially a gap 178, preferably small, exists between the ejection pin 177 and the blank 119 in the cavity 160 after the cartridges .154 and 156 are engaged and locked. After the cartridges 154 and 156 are brought into engagement and locked together, the ejection pin 177 is axially advanced into contacting engagement with the adjacent portions of the blank 119, and the blank 119 is thereby moved into contacting engagement with the adjacent forward end portions of an energy transferring hammer 174. The forming tool hammer 174 is now advanced by applying differential fluidic (preferably pneumatic) pressure into the rearward portion 173B of the enlarged channel 173A/173B. Since the forward end of the hammer 174 has been placed in abutting engagement against the blank 119, and since the pressure exerted by the hammer 174 against the blank 119 is chosen to be greater than the pressure exerted by the ejector pin 177 against the opposite side of the blank 119, the blank 119 and the ejector pin 177 are both moved by the hammer 174 advance. The advance continues until the ejector pin 177 again reaches its initial abutting or seated engagement with the compartmental back wall portion provided in a rearward portion of the second cartridge 156, as illustrated, for example, in Figs. 35 and 36. At this point in operation, the blank 119 is preferably tight against the first cartridge 154, the forward end of the hammer 174, and the forward end of the ejector pin 177. The ejector pin 177 during this phase of assembly 150 operation acts as an anvil. With the adiabatic forming apparatus 150 in the configuration illustrated, for example, in Figs. 35 and 36, the ram 178 is fired (released) by the ram operating mechanism 180, as illustrated in Fig. 36. The ram 178 impacts against the hammer 174, as illustrated, for example, in Fig. 37. At this point in operation, the blank 119 is partially formed in the cavity 160 into a part 182, the partially formed body being designated 119/182 in Fig. 37 in less than about one millisecond. After ram 178 impact, force is applied through and by the ram 178 against the hammer 174 by a mechanism as below described. Within milliseconds after ram 178 impact, and force application, the blank 119 fully is reshaped into conformity with the shaping cavity 160 and thereby is formed into a part 182 that fills the shaping cavity 160 as illustrated in Figs. 38 and 39. Brief as the forming time is, the blank 119 shaping is progressive into the formed part 182 and can be considered to occur in phases after ram 178 impact. These progressive adiabatic shaping phases are illustrated successively in the sectional views Figs 41A through 41E, and in Figs. 42A through 42E. Figs. 42A through 42E correspond to the respective Figs. 41A through 4IE. It should be understood that the process of Figs. 41B-41D takes less than about one millisecond and creates an instant heat build-up in the blank. On the other hand, the process of Fig. 41E takes a number of milliseconds depending on the RP of the machine. The force application or power stroke forming to finalize the forming process is done when the metal is already warm or hot and is done very gently. Immediately after the part 182 is thus formed, the cartridges 154 and 156 are unlocked and the second cartridge 156 is separated (retracted) from the first cartridge 154 by retracting the piston 157, as illustrated in Fig. 40. As the cartridges 154 and 156 separate, the ram 178 remains applied to the hammer 174, thereby permitting the hammer 174 to act as an ejector for separating the part 182 from the cartridge 154. Also, concurrently, as the cartridges 154 and 156 separate, the ejection pin 177 is advanced in the cartridge 156 so that the head of the ejector pin 177 is applied against the formed part 182. Thereby, the ejector pin 177 acts as an ejector to separate the formed part 182 from the second, cartridge 156. The part 182 is thus separated from the cartridges 154 and 156 and falls into a waiting collection bin (not detailed) , or the like, as desired, thereby completing a complete cycle of operation of the adiabatic forming apparatus 150.

The upper jaw 386 is supported in, nestably received in, and held by, the frame structure 380. The lower face of upper jaw 386 and the upper face of the lower jaw 387 are each generally flattened and normally these faces are in opposed, spaced, parallel relationship relative to each other. However, a matching groove 386A and' 387A is defined in each of the upper and lower faces, respectively, and the grooves 386A and 387A are adapted to accommodate side surface portions of feedstock 103 when the feedstock 103 is extended therethrough. A plurality of coiled' -springs 388 extend generally vertically between the jaws 386 and 387 in opposed facial pockets (not shown) .. The springs 388 bias the lower and upper faces of the jaws 386 and 387 into a normally spaced relationship and the springs 388 aid in maintaining a uniform spacing between these upper and lower faces. When the jaws 386, 387 are in an open configuration, such as shown in Fig. 16, the jaws 386 and 387 are slidably movable relative to the feedstock 103, or vice versa. When the jaws 386, 387 are placed in a closed configuration, achieved by upward movement of the lower jaw 387, the feedstock is grasped or clamped between the jaws 386, 387. To achieve controllable movement of the lower jaw 387, the central region of the lower face of the lower jaw 387 is associated with the upwardly projecting, outer end portion of a shaft 389. The lower end portion of the shaft 389 is associated with a piston 391. The piston 391 is reciprocatorily generally vertically movable (as shown in Fig. 15) in the longitudinally shallow chamber 392A/392B of a cylinder 393. The upper end of the cylinder 393 is provided by a top plate 395 having a central aperture 396 through which the shaft 389 slidably extends. The lower end and side walls of the cylinder 393 are provided by a mug- like structure 394. Sealing means, such as an o-ring 397 extending circumferentially around a groove in the piston 391, and an o-ring 400 extending circumferentially around a groove in the aperture 396, is provided. Access to the lower chamber portion 392A is provided by channel 398 and access to the upper chamber portion 392B is provided by a channel 399. When chamber 392A is pressurized with a compressed fluid, such as air or the like, the piston 391 and shaft 389 are elevated, raising the lower jaw 387 and achieving closure of the jaws 386, 387. When chamber 392B is similarly pressurized, the piston 391 and shaft 387 are lowered, lowering the lower jaw 387 and achieving opening of .the jaws 386, 387. As discussed below in reference to the control system and Fig. 47, the combination of cylinder 393, piston 391 shaft 389 and channels 398 and 399 can be regarded as a pneumatic cylinder 307. Similarly, each of grippers 106 and 107 can be regarded as incorporating pneumatic cylinders 301 and 302. To limit movement of the gripper 108 along the rails . 259 and 260, stop blocks 361 and 362 are provided, each one being slidably movable on the rails 259 and 260, and each one being on a different side of the gripper 108. Each block 361 and 362 is provided with an adjustable collar 363 and 364 that is threadably engaged with its associated block and that is adapted to clamp adjustably circumferentially adjacent portions of the rails 259 and 260. The movable gripper 107 is similarly provided with stop blocks. The stationary gripper 106 has a structure like that of the movable gripper 108 except that the stationary gripper 106 is mounted in an inverted orientation and is fixed to the frame 104. As shown, for example, in Figs. 14 and 15, to automatically operate and control the reciprocal movements of the grippers 107 and 108, and = ' to coordinate movements associated with the actuations of the- impact press apparatus 100 and the desired progressive locations of feedstock 103 as feedstock 103 is moved in a ' stop and go fashion by the stock feeder assembly 101 during operation of• .assembly 101 and apparatus 100, various means can be employed. Here, it is presently preferred to employ a gear train 200 that is here, as shown in Figs. 17, 18 and 19, illustratively but preferably comprised of five peripherally and successively inter-engaged gears 201, 202, 203, 204, and 205 having horizontally spaced, parallel respective axes of rotation. Each such gear is keyed to a proximal end portion of a similar shaft 206, 207, 208, 209, and 210, respectively. Each such shaft is journaled for rotational movements along and adjacent its respective opposite end portions by a pair of bearings 211A and 211B, 212A and 121B, 213A and 213B, 214A and 214B, and 215A and 215B, respectively. The frame 104 is provided with a pair of spaced, parallel support plates 218 and 219 that upstand from a generally horizontally oriented base plate 220 and that extend lengthwise under the top deck 222 (see, for example, Fig. 3) of the frame 104. The plates 218 and 219 are each provided with five apertures 223 that are transversely aligned with one another in paired fashion whereby each member of the bearing pairs 211A and 211B, 212A and 212B, 213A and 213B, 214A and 214B, and 215A and 215B is mounted in axially aligned relationship with the other. Thus, the shafts 206, 207, 208, 209, and 210 extend between the plates 218 and 219 in spaced, parallel relationship to one another and each such shaft is supported by both plates 218 and 219. The gears 201, 202. 203, 204, and 205 are conveniently covered by a protective housing 224 that is conventionally mounted to plate 218 by machine screws or the like, not detailed. A crank shaft assembly 226 is keyed to the distal end of shaft-206. An electric motor 227 and associated transmission 228 (conventional assembly) is supported through the plates 218 and 219 in spaced adjacent parallel relationship to shaft 206, and a drive crank shaft 225on the power output shaft of the transmission 228 is connected by a drive belt 229 to the crank shaft 226 whereby the motor 227 when operating can rotatably drive the shaft 206 and thereby revolve each of the gears 201 through 205 and their associated shafts 206 through 210. The gear 201 is identical to the gear 203 and the gear 205, while the gears 202 and 204 are identical to each other. The rotational speed of the individual shafts 206 through 210 is thus precisely controlled by the motor 227 and the transmission 228. Gear 203 serves as an idler gear, gears 202 and 204 each drive a crank assembly 231 and 232, as hereinbelow described, and gear 205 drives the impact press apparatus 100. To the distal end of each of the shafts 207 and 209 is connected an adjustable crank shaft 235 and 236, respectively. Each crank shaft 235 and 236 is eccentrically rotatably connected to a first crank arm 237 and 238, respectively. Each terminal end of each crank arm 237 and 238 is rotabably connected to a terminal yoke of a second crank arm 240 and 241, respectively. The initial end of each second crank arm 240 and 241 is rotatably connected to a pivot shaft 243 and 244, respectively, that is journaled by aligned bearing pairs (not detailed) each one mounted in a different aligned aperture one in each of the plates 218 and 219. Hence, rotation of the crank shafts 235 and 236 is translated into an oscillatory, or pivotal movement by each of the pivot shafts 243 and 244. Each, of the pivot shafts- .243 and 244 is keyed to the lower end of an oscillator arm 251 and 252, respectively, as shown in Fig. 3, for example. The upper end of each oscillator arm 251 and 252 is provided with a shallow channel 253 and 254, respectively, that extends inwards and lengthwise into the associated oscillator arm 251 and 251. A stub shaft 256 projecting outwardly from a downturned leg 255 of gripper 108 slidably connects with the channel 254, and a stub shaft 257, similar to gripper 108, of gripper 107 slidably connects with the channel 253. Hence, as the pivot shafts 243 and 244 oscillate, the oscillator arms 253 and 254 are caused to move pivotably relative to their shafts 243 and 244, and this pivot action moves the grippers 107 and 108 back and forth along respective portions of the rails 259 and 260. Those skilled in the art will readily appreciate that different ranges of movement and position for each movable gripper 107 and 108 are achieved by adjustments and settings of, respectively, the crank assembly 231, comprised of crank shaft 235, crank arm 237, crank arm 240, pivot shaft 243 and oscillator arm 251, and the crank assembly 232, comprised of crank shaft 236, crank arm 238, crank arm 241, pivot shaft 244, and oscillator arm 252. The stock feeder assembly 101 can, if desired, be operated without usage of the stationary . gripper 106 as when, for example, the feedstock 103 can be advanced or retracted without slippage by using only the first movable gripper 107 and the second movable gripper 108. In such an operating mode, the stationary gripper 106 can either be left in an open and non-gripping configuration or in .an inoperative configuration during apparatus 100/101 operation using only the movable grippers 107 and 108 for feedstock feeding. Alternatively, the stationary gripper 106 can be separated from, or absent from, the stock feeder assembly 101, if desired. The operating sequence in assembly 101 using just the movable grippers 107 and 108 is illustrated in Figs. 12A, 12B, and 12C. These Figs, show progressive positions of the movable grippers 107 and 108 being used without a stationary gripper 106. Their respective gripping functions corresponds to that above described when using the stationary gripper 106. Thus, the stock feeder can be operated with either two movable grippers or one stationary gripper and two movable grippers. When using two movable grippers, with the stationary gripper 106 inactivated or absent, operation of stock feeder apparatus 100 is as follows: First movable gripper 107 clamps the feedstock 103. • Gripper 107 has heen advanced to a full forward position. The gripper 107 has already advanced the feedstock 103 to a predetermined position desired for cut-off by impact press apparatus 100. After the ram 116 is fired, and the blank 119 is cut off, the first movable gripper 107 releases the feedstock 103 and the second movable gripper 108 grasps the feedstock 103, as shown in Fig. 8. The first movable gripper 107, after release of the feedstock 103, translates backwards to a predetermined rearward-most location along the pathway of feedstock 103 travel. The second movable gripper 108, while clamping the feedstock 103, advances the feedstock 103 to a predetermined extent that is sufficient to push and move the blank 119 forwardly completely out of the stationary die block 109 and into a predetermined position which, in the system 99, is a position in the transfer capsule 146. Thereafter, the second movable gripper 108, while still gripping the feedstock 103, retracts the so clamped feedstock 103, and moves it backwards along the feedstock travel pathway to an extent sufficient to place the feedstock 103 forward end about at the parting plane 155, as shown in Fig. 10. At this configuration, the second movable gripper 108 is either at or near its point of rearward-most travel, depending upon apparatus adjustments. The first movable gripper 107 now clamps the feedstock 103 and the second movable gripper 108 releases the feedstock 103. The first movable gripper 107 now advances the feedstock 103 to place the forward end region of the feedstock 103 in the desired position for blank 119 cut off by impact press apparatus 100, thus completing one cycle of operation of the grippers 107 and 108 in assembly 101. As shown by the arrows indicating directions of movable gripper 107 and 108 translation in Figs. 12A, 12B, and 12C, during operation of the assembly 101, during the sequence of stock feeder assembly 101 operation, these grippers 107 and 108 exert their respective feedstock 103 gripping functions as they move reciprocatorily along the feedstock 103 travel pathway in seemingly opposite directions relative to one another. (2) The Adiabatic Impact Press Assembly 100 The impact press apparatus 100 is comparable to the assembly shown in Lindell U.S. Pat. No. 4,470,330 and U.S. Pat. No. 4,245 > 493, the teachings of which are incorporated here by reference. However, particularly because of distinctions and improvements provided in the apparatus 100, compared to the * 330 patent teachings, an abbreviated description of the structure and operation of apparatus 100 is here provided. Referring to Fig. 4, the apparatus 100 is seen to incorporate a pair of die blocks 109 and 111 which have adjacent flat faces that are in planar but translatable engagement each relative to the other. Each has a bore 112 and 113, respectively, therethrough, and these bores 112 and 113 are normally in coaxial alignment . The die blocks 109, 111 define along and across their adjacent faces a parting plane 115. In operation, as above indicated, the feedstock 103 is advanced through the bores 112 and 113. Die block 109 is stationary while die block 111 is adapted for limited movement in a direction transverse to its bore 113 and to feedstock 103. A lower side portion of the die block 111 is associated with a head end of an energy-transferring forming hammer 114. The hammer 114 projects outwardly and downwardly from die block 111 and the outer exposed end of the hammer 114 is adapted to be impacted by a ram 116. The apparatus 100 incorporates a ram 116 and an associated ram operating mechanism 120. The ram 116 is vertically reciprocal and is driven by mechanical means (not shown) of the ram operating mechanism 120 as described in Lindell U.S. Pat. No. 4,470,330. The apparatus 100 includes an housing 122 in which the die blocks 109 and 111 are associated and which guides and limits the movements of the die block 111. The housing 122 herein collectively refers to components which cooperate and which are held together by screws or the like, not shown. The housing 122 includes a base plate 123 that is mounted to the frame 104. Base plate 123 conveniently is associated with a pair of clamping blocks (not shown) that hold a stationary spacer block 117 which retains and guides the die blocks 109 and 111 in housing 122. The housing 122 also includes a lower and an upper cap block 126, 127, respectively, and an internally threaded sleeve member 129. A cylindrical, externally threaded adjustment screw 128 threadably engages the sleeve member 129. Screw 128 is located upstream (relative to the path of travel of feedstock 103) of the die blocks 109 and 111 and the spacer block 117, and screw 128 acts to hold the blocks 109, 111, and 117 in association with each other. An internally threaded split ring clamp 124 is secured against the outer end of the sleeve member 129. Tightening of screw means (not shown) relative to clamp 124 enables the exact position of screw 128 to be maintained. A guide bushing 118 is associated with the central longitudinal region of screw 128. The bushing 118 and the spacer block 117 are each provided with an axial channel whose diameter is larger than the diameters of the bores 112 and 113. The housing 122 is associated with a positive die return subassembly 121 that includes the upper cap block 127. A cam guide block 13.3 seats against layer 132 and block 133 has a downwardly facing inclined cam surface 134. The subassembly 121 also includes the lower cap block 126 which holds a transfer block 136 that is slidably guided therein for transverse movements relative to the bores 112 and 113. A cam 137 is slidably guided in the housing 122 over transfer block 136 for lateral movements between a first position which is adjustable, as shown in Fig. 4, and a second position as shown in Fig. 5. The transfer block 136 is biased by a set of springs 138 which yieldingly urge the transfer block 136 against the bottom of cam 137 and hold the cam 137 against the cam surface 134. A small space 139 is retained between the movable die block 111 and the transfer block 136. The size of this space 139 is regulated by the extent that the cam 137 is laterally retractable from its normal rest position shown in Fig. 4 to a position such as illustrated in Fig. 5. To enable the cam 137 to be reciprocated during operation of the apparatus 100 between a first position, as shown in Fig. 4, that permits limited movement of the die block 111, and a second fixed position shown in Fig. 5, where the space 139 is consumed, the positive die return subassembly 121 is provided. The position of the cam 137 causes die block 111 movement to terminate and any excess energy is absorbed by the housing 122 in the region of the cam surface 134. A shaft 141 provided which is rockable relative to the housing 122. A crank arm (not shown) is adjustably secured to the shaft 141. An adjustable stop (not shown) limits travel of shaft 141 in a clockwise direction, thereby limiting the amount of retraction in cam 137. The reciprocably driven ram 116 also drives a transversely extending rod (not shown) in. a . suitably synchronized manner. The crank arm is sec red to the rod and is rocked thereby. Shaft 141 is. keyed to one end of a link 142 that is hinged at its opposed end to one end of a second link 143. The opposite end of link 14 ' 3 is pivotally connected to the cam 137. This . arrangement regulates the extent of the limited movement that the die block 111 can have. The rod ' as driven places the cam 137 is a selected or retracted first position (see Fig. 4) and creates the space 139. When the ram 116 is then released, the die block 111 is caused to move at high velocity relative to die block 109. The ram 116 is conveniently retracted as soon as the die block 112 has stopped its movement. The rod is then pulled positively downwardly causing the shaft 141 to rock in a counterclockwise direction. Thus, through the links 142, 143, the cam 137 is moved to the right, as illustrated in Figs. 4 and 5, causing the transfer block 136 to move against the bias of the springs 138 and thereby restore the die block 111 to its position where bore 113 is aligned with bore 112. Normally, the ram 16 is retracted and cocked, as suggested, for example, in Fig. 3. (3) The Transferer Assembly 148 The shaft 151 is here driven by a servo motor 271. The piston 168 in transfer capsule 146 is operated by using two electromagnetic pneumatic valves 327 and 328. The control of piston 168 and of valves 327 and 328 is described below. As indicated above, operation of the transferer assembly proceeds in a discontinuous or stop- and-go manner. The transfer arm 147 swings between position 145 and position 155, and in each position the arm 147is stationary until operations involving the transfer capsule 146 at the outer end of the arm 147 are carried out at each of the cut-off apparatus lOO/lOl and the forming apparatus 150. The transfer arm can be variously actuated. In place of the servo motor 271 (presently preferred) , a cam and linkage, or a pneumatic double acting cylinder can be used, for example. The drive shaft (not shown) of the servo motor 271 and the driven shaft 151 of the arm 147 are each conveniently associated with a crank shaft (not shown) , and these crank shafts are in aligned relationship with one another. Conveniently, the crank shaft on the shaft 151 has a smaller diameter than the crank shaft on the servo motor 271 drive shaft. (4) The Adiabatic Forming Apparatus 150 The adiabatic forming apparatus 150, as shown in Figs 24 - 46, and as above indicated, incorporates two shaping cartridges, or forming tools, identified for convenience as first cartridge 154 and second cartridge 156. The first cartridge 154 is stationary and is mounted in an upper portion of a stationary first support leg 152 that upstands from fixed association with a base platform 153 which is part of a frame 275 (not detailed) . The second cartridge 156 is translatably mounted so as to be generally coaxial with the first cartridge 154. The second cartridge 156 is fixedly mounted in the forward head of a piston 157 which is axially reciprocatable in a horizontally oriented cylinder 158 that is defined in a stationary second support leg 159. Leg 159 is located in laterally spaced relationship to leg 152, and leg 159 also upstands from fixed association with the base platform 153. Thus, the forward ends 161, 162, respectively, of each of the cartridges 154 and 156 are in coaxially aligned relationship. Those skilled in the art will appreciate that the first and second cartridges 154 and 156 are selected for use with a particular blank and for forming a particular part. When the piston 157 is axially advanced with the second cartridge 156, the forward ends 161,162 are brought into abutting and engaged relationship with one another and define therebetween in combination with adjacent portions of a blank 119 and an ejection pin 177 a forming cavity 160 (see Fig. 22) of predetermined internal configuration. Preferably, as shown illustratively in Fig. 15, each of the forward ends 161 and 162 is provided with carbide type inserts 163, 164, respectively, which, when the first and second cartridges 154 and 156 are so engaged, define enclosing wall portions of the cavity 160. The second cartridge 156 has an axially extending bore 176 therethrough and also through the carbide insert 164. The ejection pin 177 is slidably positioned in a diametrically somewhat enlarged forward region of the bore 176. The pin 177 is normally retracted in bore 176, and, preferably, as shown in Figure 31, for example, the rear end of the retracted pin in bore 176 is normally seated against a shoulder 178 provided in the bore 176, thereby to limit rearward travel of the pin 177. Preferably, and as shown, the edge portions of the bore 176 may protrude slightly into and form a small part of the wall surface defining the cavity 160, and the head end of the pin 177 comprises a wall portion of the cavity 160. To achieve axial reciprocal movements of the ejection pin 177 relative to the piston 157 in the cartridge 156, the rear face of the pin 177 is threadably associated, or the like, with the forward end of an elongated rod 184. The rearward end of the rod 1 ' 8.4 is associated with a fluidic (preferably pneumatic, more preferably compressed air) cylinder assembly 185 whose structure may be as detailed in Fig.- 48. Thus, referring to Fig. 48, the rearward end portion of the rod 184 extends slidably through an end opening 188 into a guidance chamber 186 defined in a cylinder 187 provided at the head end of cylinder assembly 185. The rearward end of the rod 184 is threadably associated, or the like, with the center of the forward face of a guidance piston 189 that is adapted to slidably and axially move reciprocatingly in chamber 186. The rearward face of the guidance piston 189 is engaged axially with the forward end portion of a shaft 191 that extends through aligned apertures 198 and 199, respectively, defined in each of the forward end plate 196 of a cylinder 193 employed the cylinder assembly 185 and also the base plate 197 of the cylinder 187. The rear end of the shaft 191 is engaged axially with a piston 192 that is adapted to move slidably and axially move reciprocatingly in the forward chamber 193B of the cylinder 193 of the cylinder assembly 185. For purposes of providing a seal between adjacent components, the piston 192 is provided with a circumferentially extending seal 194, and the aperture in the end plate 196 of the cylinder 193 is provided with a circumferentially extending seal 266. Pressurized fluid input through channel 267 into rearward chamber 193A of the cylinder 193 causes the piston 192 to advance together with the shaft 191, and pressurized fluid input through channel 268 into forward chamber 193B causes the piston 192 to retract with the shaft 191. Since shaft 191 is connected to rod 184, rod 184 moves with shaft 191, and hence the ejection pin 177 is reciprocated. The first cartridge 154 has an axially extending channel 173 extending therethrough. The forward end portion of the channel 173 is preferably configured to. receive slidably therein the blank 119. The channel 173 also extends through the carbide insert 164. A mid portion and a rearward portion of the channel 173. are enlarged diametrically. An energy- transferring elongated hammer 174 extends through the channel 173. The hammer 174 is diametrically thickened in its mid region and there provided with outside walls that are configured to slidably engage the enlarged portions of the channel 173. The hammer 174 is also adapted to reciprocably move in channel 173 responsive to differentially applied fluidic pressure (preferably pneumatic)., as those skilled in the art will appreciate. Channel 172, at each end of its enlarged mid-region, is provided with fluid input ports (not shown but described below) . Various arrangements are possible for the hammer 174 and the channel 173. Preferably, and as shown, the rearward end of the hammer 174 protrudes out from the rear face of the cartridge 154. The adiabatic shaping apparatus 150 is provided with a ram 178 and a functionally associated ram operating mechanism 180. The ram 178 is axially positioned relative to the hammer 174 so as to strike the adjacent end of the hammer 174 perpendicularly when the ram 178 is released (fired) by the ram operating mechanism 180. Structural details of the ram operating mechanism 180, which includes a ram firing mechanism, a ram force applying mechanism, and a ram retracting mechanism, are described below. To operate the adiabatic shaping apparatus 150, a gear train 280, as shown in Figs. 43 - 46, of seven peripherally inter-engaged gears 281, 282, 283, 284, 285, 286, and 287 with horizontally spaced, parallel respective axes of rotation is employed. Each . of the gears 282, 283, 284, 285, 286, and 287 is identical to the others and is keyed to one end of a shaft 292, .293, 294, 295, 296, and 297, respectively. Gear 181 is keyed to the output shaft 291 of a transmission 289 that is energized by an associated electric motor 290. The rotational speed of the individual shafts 292 through 297 is thus precisely controlled by the motor 290 and the transmission 228. The motor 290 continuously operates during the operational sequence of forming apparatus 150. Gears 283, 284, 285, and 286 are idler gears. Gear 282 and gear 287 are each eccentrically and rotatably associated with a driven end of an eccentric crank arm 299 and 300, respectively. The opposite driving end of each crank arm 299 and 300 is rotatably connected to a connecting pin shaft 301 and 302, respectively. Shaft 301 joins the respective proximal ends of each of a pair of toggle links 401, 402 with the driving end of arm 299. Shaft 302 joins the respective proximal ends of each of a pair of toggle links 403, 404 with the driving end of arm 300. The distal end of the link 401 is pivotably associated with a spatially stationary pin shaft 406, and the distal end of the link 404 is pivotably associated with a spatially stationary shaft 407. The pin shafts 406 and 407 are each held by the frame 275, and these shafts are generally aligned with the working axis of the cartridges 154 and 156, but each shaft is outwardly spaced from the adjacent cartridge . The distal end of the link 402 is pivotably joined to the outer end of a secondary link 408 by a pivot pin 409, and the inner end of the secondary link 408 is pivotably joined to the center of the outside end of the piston 157. The secondary link 408 is employed to compensate for the maximum kink angle of links 401 and 402, thereby to avoid interference of links with the cylinder 158. The distal end of the link 403 is pivotably joined to the center of the outside end of the adiabatic press assembly 165. As the gears 182 and 187 rotate, the arms 299 and 300 cause each of the respective link pairs 401, 402 and 403, 404 to move from a configuration of maximum flexure or kink, relative to their respective associated shafts 406 and 407, such as shown in Fig. 43, to a straight configuration, such as shown in Fig. 45. When links 401, 402 are in their straight configuration, the cartridges 154 and 156 are engaged and effectively locked together. When the links 403 and 404 are in their straight configuration, the ram 178 is contacting the hammer 174, and the hammer 174 has been advanced to its location of maximum forward advance; this αo TJ 4-) φ >i β Φ Φ r-i rl J Φ φ Φ CQ A 4-> (ti tn β H (ti Φ Φ 0 β Λ A CJ) 1 Q ε rl 4J CQ & J ■ H A •rl r-i C & CQ -H 4-) 4-) J 4-> 5-1 β -H -rl 3 A J Φ •rl (ti X •H 4J 3 Λ; -H ( ti CQ (ti 0 4-1 4-1 Φ φ 4-) O β υ 5H Φ (ti A -rl (ti r-i J 4-1 β 5^ β ti -H 0 r- A Φ -rl (ti .

This pivot movement swings the arm 416 and causes the driven end of arm 416 to apply sufficient force to the locking ring 62 to slide this ring forward and release the ram 178. The electrical energy for activation of this servo motor is controlled to occur when the spacing between the protruding en of the hammer 174 and the ram 178 position has reached a predetermined distance. The amount of impact force to be delivered by the ram 178 when released at the predetermined distance is preliminarily selected and set as a preliminary adjustment of the impact press assembly 165 operation. In place of a gear driving arrangement as above described, various alternative arrangements can be used. One alternative arrangement is illustrated in Figs. 49 and 50 where a pair servo motors is employed for operating a similar gear for flexing each of the toggle link pairs. Another alternative arrangement is illustrated in Figs 51 and 52 where a pair of concurrently operating pneumatic or hydraulic cylinders are employed, one for flexing each of the toggle link pairs. Here, each cylinders push rod is utilized to pivot a lever arm, and a gear on the axis of each lever arm is utilized to turn a connected drive gear. Each drive gear is eccentrically connected to a lever arm crank that kinks and unkinks the toggle link pairs. (5) The Control and Synchronizing Assembly As indicated above, translation of the elongated feedstock 103 in apparatus 100/101 proceeds in a stop- and-go or discontinuous manner. The feedstock 103 momentarily stops translating in a single cycle of apparatus operation at each of the following times: (a) Forward translation of feedstock 103 is stopped when blank 119 is being cut-off at the feedstock 103 forward end by the impact press 100; (b) Forward translation of feedstock 103 is stopped after the cut-off blank 119= has been pushed forwards by the feedstock 103 forward end into the transfer capsule 146 and before reverse or rearwards translation of the feedstock 103 starts, and (c) Rearward translation of feedstock 103 is stopped before forward translation- of the feedstock 103 commences for the purpose of permitting the feedstock 103 forward end to be advanced (translated) and positioned at the impact press 100 (for a repeat of stop (a) ) . Since the operations of adiabatic impact press assembly 100 and the stock feeder assembly 101 are driven and controlled by the common gear train 200, the operational movements of the impact press 100, and of the grippers 106 (if used) , 107, and 108, are precisely synchronized so that the above indicated desired discontinuous cyclical operation is achieved. However, as those skilled in the art will readily appreciate, various apparatus parameters can be adjusted to accomplish desired changes. For example, adjustments can be made in impact press 100 operating characteristics, such as impact force, or in stock feed 101 operating characteristics, such traverse travel distance of each of the first and second movable grippers 107 and 108 in reciprocation, or the like. Such adjustments may be desirable when a feedstock or a blank to be produced is being changed. As above explained, and as indicated in Fig.. 47, for example, the on/off operations of the jaws of the respective grippers 106 (if used) , 107 and 108 are each determined by operation of a functionally associated, conventional-type, commercially available, double- acting, pneumatic cylinder (PC) . Each such PC cylinder here employed has two longitudinally adjacent chambers, and a single reciprocatable piston means located in the cylinder between the chambers. A rod or body means associated with the piston means extends generally axially in, and projects beyond one end of, the associated cylinder. Sealing means of course is included. Each chamber of each cylinder is conveniently connected with a separate conduit means for providing that chamber with a pressurized fluid (preferably compressed air) . Various operational control arrangements can be used. For example, each conduit means that is so associated with a different one of a cylinder's two chambers is conveniently functionally associated with a conventional, commercially available, electromagnetically actuated, double acting, pneumatic valve assembly (EPV) . Two EPV valve assemblies per PC pneumatic cylinder are utilized. Each EPV valve assembly incorporates a first and a second electromagnetically actuatable valve (not detailed) , and each valve is independently actuatable and controllable by an appropriate input electric signal. Both valves of each EPV valve assembly are normally (when not actuated) in a closed configuration. As indicated in Fig. 47, the movable jaw of each gripper assembly 106, 107, and 108 00 © -f. a. . « « o* ■ oo oo © o Such a pressure/volume reduction in the second chamber 301.2 is achieved by opening the second valve of the second electromagnetically actuated EPV valve assembly 303 (while maintaining the first valve of the second EPV valve assembly 303 in a • closed configuration) . EPV valve assembly 303 is functionally associated with the second conduit 311 that is connected to the second chamber 301.2 of the same cylinder of the PC cylinder assembly 301. This second valve of EPV valve assembly 303 is associated with a vent (not shown) to the atmosphere. Opening this second valve permits gas (air) that may be under pressure in the second chamber 301.2 to pass out via the .second conduit 311 through the open second valve and vent to the atmosphere. Preferably, the second valve of the second EPC valve assembly 303 is opened concurrently with the opening of the first valve of the first EPC valve assembly 302 so that gas (air) pressure which may exist in the second chamber 301.2 of the cylinder of the PC cylinder assembly 301 is released as pressure in the first conduit 310 and connected first chamber 301.1 increases. Similarly, EPV valve assemblies 305 and 306 each connect with respective conduits 312 and 313 that in turn each connect with a different chamber 304.1 and 304.2 of the pneumatic cylinder (PC) 304; and EPV valve assemblies 308 and 309 each connect with respective conduits 314 and 315 that in turn each connect with a different chamber 307.1 and 307.2 of the pneumatic cylinder (PC) 307. Pneumatic cylinder 301 operates (closes or opens) the lower jaw of fixed gripper 106, pneumatic cylinder 304 operates (closes or opens) the lower jaw of movable gripper 107, and pneumatic cylinder 307 operates (closes or opens) the lower jaw of the movable gripper 108. In order to control and synchronize opening and closing operations of the individual electromagnetic valve assemblies 302, 303, 305, 306, 308, and 309, and hence operations of their associated PC cylinder assemblies 301, 304, and 307, and the opening and closing operations of the grippers 106 (if used) , 107 and 108, various arrangements can be used. A present preference is to associate the shaft of a gear, such as the-shaft 207 of the gear 202 (see Fig. 19) , with a conventional, commercially available, electromagnetic shaft rotation position sensor (SRPS) 350 which is able to (a) selectively identify, relative to a starting location for shaft 207 rotation, successive and progressive shaft 207 positions existing during every 360 degrees of shaft 207 rotation, and (b) generate electric signal outputs that are representative of shaft 207 angular positions and rotation. Since the respective electric signals produced by the shaft rotation position sensor 350 correspond to shaft 207 positions of rotation, and represent time intervals, the signals are suitable for use, during the course of a stock feeder 101 cycle of operation, in regulating the operation of the jaws of each of the grippers 106 (if used) , 107 and 108. A system for achieving such control of gripper jaw activation is illustrated in the simplified schematic diagram of Fig. 47. The output from the shaft rotation position sensor (SRPS) 350 is fed to a signal generator (SG) 351. For example, an analog signal from sensor 350 can be converted to a digital signal, and the output signal of signal generator (SG) 351, which is representative of the currently existing shaft 207 operative configuration, is adapted to be charged to a computer controller (C) 352 which has been programmed with shaft 207 positions that correspond to particular times and locations where activations and deactivations of the respective jaws of the grippers 106, 107 and 108 are desired. The controller 352 compares these programmed positions to the signals being received from the shaft rotation position sensor 350 via the signal generator 351. When a signal from shaft rotation position sensor 350 is found by the controller 352 to correspond to a programmed position for a gripper jaw activation, then the controller 352 generates an output signal which is received by an encoder (E ' )- 353. A control line 371 interconnects the encoder (E) 353 with each of these six EPV valves and the servo motor 271. The encoder 253 is programmed with the unique location identification code or address for each one of the six electromagnetically actuated pneumatic valve assemblies (EPVs) 302, 303, 305, 306, 308, and 309 and also for the servo motor (SM) 271. When, for example, the controller 352 identifies a shaft 207 position where a particular gripper jaw is to be activated, the controller 352 sends an information signal to the encoder 353 which accepts that signal and (a) labels it with the unique location identification codes for each of the two involved electromagnetic valves to be activated is located along the control line 271, and (b) converts it into an activation signal for use by each one of the two involved electromagnetic valves to be activated for operating the associated cylinder assembly and the jaw of the desired gripper. Thus, in the illustration, from the input signal received from the controller 352, the encoder 353 provides signal means that is adapted to activate the first valve of the first EPV valve assembly 302, and signal means that is adapted to activate the second valve of the second EPV valve assembly 303. When the first valve of the first EPV valve assembly 302 is actuated, compressed air is admitted to the first chamber 301.1 of the PC cylinder assembly 301, and when the second valve of the second EPV valve assembly 303 is actuated, pressurized gas (air) is released from second chamber 301.2 of the PC cylinder assembly 301. Preferably such first and second valves are concurrently actuated. After a given gripper jaw has been activated (closed) for the desired time interval, the termination of that time interval is identified and detected by signals received by the controller 352 from the shaft rotation position sensor 350 via the signal generator . 351, and a signal is sent by the controller 352 to the encoder 353. After processing, that signal is effectively forwarded to the two involved EPV valve assemblies, and, upon receipt, the respective operations of these EPV valves are reversed relative to the valve actions that occurred upon initial PC cylinder assembly activation; that is, the second valve of the first electromagnetic, valve assembly is energized, while the first valve of the second electromagnetic valve assembly is energized, thereby resulting in operating the lower jaw and opening the jaws of the involved gripper. The involved gripper' s jaw then remains in an open configuration until a subsequent signal is received by the controller 352 from the shaft rotation position sensor 350. That subsequent signal marks the time when that, gripper' s jaws are again closed, and the process operation is repeated. Thus, the operation of the jaws of the grippers 106, 107 and 108 is controlled. After a blank 119 is cut off from the feedstock 103, and is advanced into. the transfer capsule 146, then the transfer capsule 146 and the transfer arm 147 are ready to be moved from the position 145 at cut-off assembly 100/101 to the position 155 at the forming assembly 150. To accomplish this movement; the servo motor 271 of the transferer assembly 148 is energized for the time interval needed to accomplish such arm 147 movement. This time interval is preferably predetermined or preset, but, alternatively, a microswitch (not shown) can be located at each of the positions 145 and 155 and used to de-energize the servo motor 271 upon arrival of the arm 147 at a position 155 or 145, as those skilled in the art will readily appreciate . To control the time point where activation of the servo motor 271 is to occur, which is usually the time when the blank 119 fully-charged into transfer capsule 146 and the arm 147 is able to swing without interference from the feedstock 103, various control means can be employed. One convenient and now preferred control means is to utilize the shaft position rotation position sensor SRPS 350. When the controller C 352 receives a control signal from the shaft rotation position sensor SRPS 350 via the signal generator SG 351, and the controller C 352 outputs a resulting signal to the encoder E 353, an activation signal is provided for the servo-motor 271 and the arm 147 is swung as desired.
