Abstract

A cold drawing die for drawing round bar stock into shapes such as polygons acts continuously on the full circumference of the round bar stock to uniformly deform the stock and yield polygons to exacting specifications using a starting material only slightly larger than the maximum diameter of the finished shape. A pure polygon and a hybrid polygon shape are disclosed. <IMAGE>
