Abstract
1308245 Press feed mechanisms WICKMAN MACHINE TOOL SALES Ltd 20 July 1971 [5 June 1970] 27180/70 Heading B3Q A coining press feed mechanism comprises a pair of parallel arms 32 each with a pair of gripper jaws 6, 7 mounted on a carrier 4 which can be reciprocated horizontally and vertically so that workpiece blanks gripped by the jaws 6, 7 can be raised before horizontal transfer and are not scratched as in normal feed mechanisms. The reciprocations are produced by a pair of pneumatic piston-cylinder motors 12, 23 and bolts 15, 16, 25 provide adjustable end stops. Each arm 32 is pivoted to the carrier and is bellcrank shaped with one limb carrying the jaws and the other limb extending towards the longitudinal axis of the carrier and having a vertical drive pin (34), Fig. 3 (not shown). The pins are moved by an actuating member 36 driven by a pneumatic piston-cylinder motor 38 on the carriage. The inner pair of jaws 6 are spring-mounted on the arms 32 and retract when gripping a blank to operate a microswitch 42, whose signal allows further operation of the feed mechanism. The jaws 6, 7 are made of plastics to prevent damage to the workpieces. In operation the mechanism receives a blank in the jaws 6 at a stop member 44 of a feed vibrator 45. The blank is gripped by the jaws and raised for horizontal transfer to a coining press where it is lowered on to the lower die. Simultaneously the jaws 7 grip a formed blank in the coining press, raise it and transfer it to an unloading station with a feed vibrator 46.
