Abstract

A guide pin assembly for metal forming dies includes a cylindrical guide pin body with an external retainer groove adjacent one end thereof in which a retainer ring is received. An annular guide pin ring with an outside diameter greater than the pin body, has a counterbore adjacent the outside end thereof and a retainer groove in a medial portion thereof which receives the outer portion of the retainer ring to securely interconnect the pin body and the ring and thereby form an enlarged head at one end of the pin body which positively limits reciprocal motion between two associated die members. A circular guide pin head cap covers the outer end of the head ring, and includes a support collar that is closely received in the counterbore of the ring, and engages the retainer ring to securely hold the same in place.

First claim

The invention claimed is:

1. A guide pin assembly for metal forming dies having first and second die members which mutually converge and diverge to form metal parts, comprising:
a guide pin body having a generally cylindrical shape, with a predetermined outside diameter, and including:
a first end portion configured for secure operable attachment with the first die member;
a second end portion disposed generally opposite said first end portion, and configured to be received int…
