ABSTRACT:
A guided keeper assembly and method for metal forming dies includes a base having a flat mounting face and at least one marginal fastener aperture to detachably mount the base to an associated die shoe, as well as a central guide aperture. The assembly also includes a guide pin having a central portion closely received in the central guide aperture of the base for precisely guiding reciprocal motion between the die pad and an associated die shoe. The guide pin has an enlarged head at a first end thereof which abuts the mounting face of the base to positively limit travel between the die shoe and the die pad, and a shoulder at the opposite or second end thereof with an alignment mechanism that precisely locates the second end of the guide pin on the die pad. A first fastener extends through the marginal fastener aperture in the base to securely, yet detachably, connect the same with the die shoe. A second fastener securely, yet detachably, connects the second end of the guide pin with the die pad.
