Title: Apparatus for removing flashings from castings and other workpieces
IPC: B24B49/16
Filed: 1974-09-16
Abstract: 1433709 Grinding K CHIJIIWA 16 Sept 1974 [17 Sept 1973] 40299/74 Heading B3D An apparatus for automatically removing flashings 3 from castings or other workpieces W comprises a hone 1, first air spring means A arranged to resist a first component FN in a direction normal to the hone grinding surface of a force produced during grinding, second air spring means B arranged to resist a second component FT in a direction tangential to the hone grinding surface of the force, means for supplying both air spring means with air under a pressure set in response to a characteristic of a flashing of the workpiece, first and second differential transformers C, D for converting displacements of the first and second air spring means to first and second electric signals, respectively, and first and second motors M1, M4 for controlling movement of the workpiece in the directions of the first and second components in response to the first and second signals, respectively. The hone 1 is carried by a stand 16 and rotated by a belt drive from a motor M5 on a supporting stand 2. The air spring means A, in the form of a bellows, and the differential transformer C are disposed between the stands 2, 16, a further bellows A<SP>1</SP> supplied with air at a pressure equal to or less than that supplied to the bellows A acts as a stabilizer. The stand 2 projects from a plate 13 having nuts 14 engaged by a screw 12 rotatable in a pillar 11 by a motor M3 to vertically adjust the hone. The pillar is carried by a stand 30 pivotally adjustable by a vertical stub spindle 42 on a stand 10 on a base 7. The workpiece W is carried by a stand 4 rotatable on a stand 5 by a motor M4. The stand 5 is movable on a stand 6 by a screw rod 9 driven by a motor M2 in a Y direction, the stand 6 being movable on the base 7 in an X direction by a screw rod 8 driven by motor M1. The hone is carried by a shaft 32 supported for rotation in bearings 20, 21 in pressure plates 18, 19 and for axial movement in bearings 22, 23 in a barrel 24. The pressure plates are slidable in the barrel in response to air pressure supplied to the second air spring means B, in the form of a bellows, acting on plate 18 against pressure supplied to a second bellows B<SP>1</SP> acting on plate 19. A lever 27 extends from plate 18 and contacts the core 37 of the differential transformer D. The air pressure supplied to bellows A is determined by feeding the workpiece towards the hone, without rotation of the workpiece, by drive of the motor M1 until the flashing at the point engaging the hone is ground away, the grinding force being the component F N , such force determining the air pressure which is set by a valve, and the core of the differential transformer C is set to neutral. The workpiece is then rotated to set the air pressure to bellows B to determine the component of force F T . The air pressure to bellows A<SP>1</SP>, B<SP>1</SP> is then set to be equal or less than that set for bellows A, B, respectively.

A machine tool comprises a magazine 7 containing tools 8 in sleeves 15 having rollers 16 engaging a track 18, part of the track being formed in a cradle 19 which can be oscillated by fluid-pressure means (28). The magazine is carried on a slide 5 on a vertically-movable beam 4. A device 9 transfers tools from the magazine to, a spindle 6. The tool-sleeves 15 are each supported on a pivot 14. A tool at the tool-change station is rocked about its pivot by rotation of a pinion 24 by racks reciprocated by the fluid-pressure means (28) against the pressure of a safety spring (35). A switch 39 co-operating with a protuberance 41 indicates when a tool is properly positioned at the tool-change station and a fork 50 further ensures correct positioning of a sleeve as it is swung down. Should the fork 50 cause movement of the tool, consequential movement of the drum is taken up by springs 44 on both sides of a worm 43 which conveys the drive to the drum from an hydraulic motor (49).

At least three air boxes are located serially along and beneath the grate, air and steam being delivered upwardly through a bed of carbonaceous material, e.g., lignite, on the grate, from the two boxes nearest the output end of the apparatus, and hot gases (N 2 , CO, CO 2 , O 2 ) being drawn downwardly through the bed into the first box. The air and steam supply is controlled to cause limited combustion of the lignite sufficient to raise the bed temperature over the middle box to initiate the water gas reaction, i.e., to above 1830 F., and the lignite passing over the last box is quenched with steam, optionally with water, to a temperature below 1470 F. to initiate the reaction C + 2H 2 O = CO 2  + 2H 2 . The quenched lignite is then cooled with steam in the shaft in the absence of air and passed through a tumbler to a screen which separates coke and ash from the required activated char. The down-drawn gases may be sent to atmosphere through a scrubber or may be injected into the apparatus near the outlet end and sent to atmosphere through a waste heat boiler, see Fig. 2, (not shown).
