Title: Hydraulic system for dies
Inventor: WILLIAMSON FLOYD MITCHELL
IPC: B21D24/02
Filed: 1965-09-21
Abstract: 1,092,869. Forging presses. DI-DRO ENGINEERING CO. Sept. 21, 1965, No. 40170/65. Heading B3Q. An hydraulic cushion for a crank type press includes a piston 22 slidable in cylinder 10 in a fixed bolster 20 beneath a spring balanced die 24, the underside of the piston being supplied by a valve 16 either with low pressure fluid from a tank 12 or with high pressure fluid from a booster 14. Before a stamping operation on a blank 26 commences, fluid is supplied to the piston from the tank 12 via line 38, conduits 54, 48 and 46, and line 36. A solenoid operated valve 18 then operates to direct high pressure air from a cock 76 to the booster 14, the air causing a composite piston 70, 68 to rise to force fluid under high pressure through line 44. A valve spool 110 is urged upwardly against its spring bias to cut off the connection between conduits 46 and 54 and to permit the fluid to pass through a check valve 107 to the piston 22. The die 24 is thus raised so that during stamping, the fluid cushions the stamping force while causing the die 24 to be forced downwardly. This causes a rise in pressure in the cylinder 10 resulting in the valve spool 110 being forced downwardly. The fluid under pressure is vented to the tank 12 and can pass through a clock valve 62. The normal tank pressure in the cylinder 10 serves to strip a finished workpiece from the die. A number of such pistons 22 can be provided for the die 24, and an upper die ring 29 can similarly be provided with pistons, a second hydraulic system being provided for them. The pistons for the die or die ring may be divided into two groups controlled independently by separate hydraulic circuits. In place of the booster 14 a piston and cylinder assembly may be used, a piston being movable with the ram of the press to produce a high pressure in the operating fluid.

The shape or dimension of a work-piece is tested or determined by projecting converging beams of light thereon, coincident images being formed by opposed beams when the required shape is achieved. A master work-piece 11 on a support 10 has marks 12, 13, 14, e.g. in white paint which after height adjustment of pillars 23 are photographed on plates 24 in opposed optical systems 15, 16. Masks produced from plates 24 and placed in identical positions to the plates are used to project beams of light on to a rough work-piece 25 which replaces the master 11 on support 10. Images 26, 27, 28, Figs. 4 and 5, are produced on the work-piece 25 and excess material is removed from the work-piece 25 until three pairs of coincident images are formed corresponding to the marks 12, 13, 14 on the master. The workpiece then has the same dimensions as the master. The masks need not necessarily be produced by photography. Reference has been directed by the Comptroller to Specification 863,868.

Abstract: 979,114. Time switches. A. EISEN. Nov. 1, 1962, No. 41383/62. Heading H2B. A cam 6 of synthetic resin material is driven by a clockwork mechanism (not shown) and has a step reinforced by a metal plate 22. A contact-carrying leaf spring 16 overlies an auxiliary spring 20 which carries an insulating distancepiece 21 passing through a slot in spring 16 and normally engaging a leaf-spring 15 to hold it out of contact with spring 16. As cam 6 rotates the end of spring 20 first drops off plate 22 and the contact springs 15 and 16 engage, as shown. After a time interval the spring 16 also drops off the plate 22 and contact between springs 15 and 16 is broken, the distance piece 21 preventing spring 15 from following spring 16. The spring 20 is longitudinally slidable by means of adjusting screw 18 which engages a flange 19 serving as a nut; the overlap of springs 16 and 20 is thus adjustable, and therefore the time for which the circuit between springs 15 and 16 is closed can be controlled. Three cams, respectively on the seconds, minute and hour shafts of the clockwork, are provided (Fig. 1, not shown) and the contact spring assembly may be moved to co-operate with a selected cam by sliding along a fixed rod 13. Backlash in the clockwork is prevented from affecting the switch by means of an auxiliary gear-wheel having a spiral spring brake on its shaft (Fig. 2, not shown). A separate contact spring assembly may be provided for each cam and these may control different circuits or be inserted in series in the same circuit. The cams may be driven by supplementary gearing from a main clock and be manually adjustable in relation to the hands of the main clock.
