Abstract: A punch or die component for a press brake apparatus includes a tool body having a coupling end adapted for coupling with a holder, and a working end adapted for operation on a workpiece. One or more magnetic elements can be adapted for selective engagement of the punch or die component within a press apparatus by magnetic coupling with the tool body, where the working end is configured for forming the workpiece by operation of the press apparatus. The magnetic coupling can be defined between the tool body and holder disposed adjacent the coupling end, or between the tool body and an adjacent punch or die component disposed along a side surface of the tool body, or both.

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.

Abstract: A multiple punch and die assembly adapted to be placed in a punch press having a punch ram for imparting movement to a selected punch assembly for carrying out a punching or forming operation comprises a punch assembly for holding a plurality of selectively operable punches mounted for independent movement in the punch assembly so as to 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 by a pair of tabs located on a lower circumference of the striker body, said pair of tabs located on a lower circumference of the striker body with a radial separation other than 180 degrees.
