Abstract

See full text

A stock lifter for metal forming dies includes a self-contained assembly. The assembly includes a guide pin that reciprocates within a base. A hardened end cap, which contacts the stock, is attached to the guide pin. A spring is located on the exterior surface of a portion of the base and surrounds the guide pin body. One end of the spring contacts a surface on the cap, while the other end of the spring contacts a surface on the base or an optional mounting flange that is attached above the base. Thus, the stock lifter assembly has a hardened cap for the stock to slide on and a larger, externally mounted spring that provides longer life for the stock lifter. The stock lifter assembly can be made of several different lengths and sizes by using longer or wider guide pins and springs.
