Abstract

Official abstract text for this publication.

A pilot assembly with a self-contained stripper and method for metal forming dies has a cylindrical pilot with internally mounted reciprocating ejector pins with outer ends that protrude through holes in the body of the pilot to strip stock from the pilot. The pilot assembly is secured to the die by a window mount such that one or more surfaces of the pilot abut surfaces on the window mount and die to secure the pilot to the die and window mount when the window mount is secured, via a fastener, to the die. A spring within the pilot assembly contacts an end of the ejector pins to force the pins to reciprocate when the dies are pulled apart. The assembly can be made without the locating pilot surface to provide a stripper assembly for stripping the stock from the associated die.

First claim

Opening claim text (preview).

The invention claimed is: 1. In a multi-station progressive metal forming die having at least two mutually converging and diverging die members between which an elongate stock strip is shifted longitudinally to form parts from the stock strip, the improvement of a modular pilot assembly with self-contained stripper, comprising: a generally cylindrically shaped pilot operably supported on one of said die members and having an outer end portion oriented toward the stock strip, an op…
