ABSTRACT:
A device for selectively securing a stripper plate on a punch guide assembly. The device includes an annular retaining ring adapted to retain the stripper plate on the guide assembly. A resiliently biased plunger is disposed adjacent the guide assembly, and selectively maintains the retaining ring in a predetermined rotational position relative to the guide assembly. The retaining ring includes at least one retaining surface, and the guide assembly includes at least one flange for selective engagement with the retaining surface to secure the retaining ring and guide assembly against relative axial movement. A method is disclosed including the steps of placing the stripper plate on the guide assembly, placing the retaining ring on the stripper plate, and affecting relative movement between the retaining ring and the guide assembly to cause the retaining projection to engage the flange, and the plunger to be received in a locator slot on the retaining ring.
