ABSTRACT:
A workpiece transfer apparatus (10) for a punch press (12) including a first jaw (80) for engaging one side of workpieces (16) progressively forming die stations, and a second jaw (82) for engaging the other side of the workpieces (16). The reciprocating motion of the press ram (14) oscillates a first (34) and a second (36) rocker arm in unison. The first rocker arm (34) is connected to the first jaw (80) through a first clutch (26) and the second rocker arm (36) is connected to the second jaw (82) through a second clutch (28). As the rocker arms (34, 36) oscillate, they drive the jaws (80, 82) longitudinally of the die stations to progressively index the workpieces (16) from one die station to the next. When a predetermined level of resistance against one of the first (80) or second (82) jaws is encountered during operation, that respective first (26) or second (28) clutch will disengage the associated rocker arm (34, 36) while the other first (80) or second (82) jaw remains operatively connected to its rocker arm (34, 36).
