Abstract

A punch guide sleeve and stripper plate assembly useable with a punch set of the type having a punch disposed within the punch guide sleeve and adapted to be reciprocally advanced through an opening of the stripper plate attached to one end of the punch guide sleeve by the ram of a punch press. The stripper plate assembly includes a rotatable stripper plate cap which may be manually rotated with respect to the guide sleeve end from a locked to an unlocked position to secure and release the stripper plate through tightening and loosening a retaining wire onto and away from the stripper plate. The retaining wire is preferably substantially circular in cross-section and split to provide two unconnected ends that are attached to the stripper plate cap and the guide sleeve. When these two ends are drawn together in the locked position, the arcuate wire will be diametrally compressed for engagement with the stripper plate. Preferably, a spring loaded button and catch arrangement is provided that releasably locks the stripper cap in the locked position to maintain the retaining wire in contact with an annular edge portion of the stripper plate.
