Punch holder with stripper arrangement.

摘要

A punch holder (10) is described having a stripper arrangement composed of an annular array of nested coil springs (82,84) housed within a series of aligned facing bores (72-78) in a punch holder tang (12) and punch holder body (20) to generate a high stripping force in a compact space. A threaded removal ring (100) is employed to force a press fitted stripper cap (86) off the end of the punch holder body (20). A support ring (106) can be employed to support the stripping cap (89) for small sized punches (42), or a metal reinforcement (138) molded into the stripper cap (86).
