Abstract
A multiple punch and die assembly adapted to a punch press for carrying out a punching or forming operation comprises a punch assembly for holding a plurality of selectively operable punches that selectively engage a workpiece. The punch assembly has a punch carrier for reciprocal motion within a punch guide and a striker body engaging the punch carrier, said striker body being selectively, toollessly connectable to the punch carrier while permitting relative rotation of the striker body and punch carrier to select a punch for engagement by the striker. A detent means releasably positions the striker body in one of a plurality of operating positions, at which a punch is positioned for being struck selectively by the ram via the striker body such that one punch is driven to an operating position when at least one other punch is inactive, the inactive punches engageable by a lock plate.
