Patent ID: 8464928

Claim:
A multiple punch apparatus adapted to be placed in a punch press that has a punch ram for imparting axial movement to a punch within said assembly for carrying out a punching or forming operation comprising, a punch assembly having a plurality of selectively operable punches mounted in circumferentially spaced locations for independent reciprocating movement within the punch assembly to engage a workpiece when in an operating position, each of the punches being exposed in a released condition for being grasped manually at an upper end of the punch assembly, and each punch has two or more components including a punch driver component at an upper end thereof and a punch head component at a lower end that is connected by screw threads to the punch driver to permit adjusting the length of the punch when the punch is lifted by an operator relative to the punch assembly; wherein the punch driver component and punch head each have a key thereon and the punch assembly has at least one key slot for the key of the punch driver and at least one key slot for the key of the punch head, the punches are removable from the punch assembly in an upward direction for enabling the punches to be lifted at least partially out of the punch assembly such that the key of the punch driver is lifted out of the slot thereof in the punch assembly, such that an operator is then able to turn the punch driver while the punch head remains stationary with the punch head key engaged in said key slot to allow adjustment of the punch length, whereby punch length adjustment can be accomplished by an operator without the use of any hand tools.
