Multipunch with axial retainer for securing multiple dies or strippers

摘要

A multiple punch and die assembly body member has dies or strippers that are held within multiple pockets in a multipunch body member by means of a centrally positioned retaining member formed from a rigid or flexible material located in a central recess at the middle of a ring of the surrounding dies or strippers. The retaining member is preferably held in place by a push plate that can be secured to the multipunch body member by a tightening element, e.g., a screw fastener for pressing the peripheral surface of the retainer member into engagement with the dies or strippers to hold them in their respective pockets in the multipunch body member.

主权项

1. A multipunch body for a multiple punch and die assembly adapted for installation into a punch press comprising:
a multipunch body member that includes a ring of pockets wherein each pocket holds a die or stripper that is removably mounted therein, the multipunch body member also having a central recess within the ring of pockets in the body member and communicating radially therewith, a plurality of punches slidably mounted in the multiple punch and die assembly in alignment with the pockets, a retaining member held in the central recess of the body member, said retaining member has a peripheral surface extending therearound that is constructed and arranged to be expanded radially and thereby hold at least one of the adjacent multiple dies or strippers to thereby clamp the at least one adjacent die or stripper within the pocket therefor as the dies or strippers cooperate with the punches during operation of the punch press.
