ABSTRACT:
Methods of and apparatus for the production of wire are presented. Previously, the most economic and popular process was drawing. In each pass, a small reduction was obtained and normally several dies in tandem were mounted on a single wire drawing machine. The process was continuous and precision wire was made. Also in the prior art, traditional rolling was a continuous process, but was limited to heavy and medium gauge, to small reductions per pass, and to poor dimensional and surface control. In comparison, traditional extrusion and hydrostatic extrusion are capable of large reductions, good dimensional control and surface finish, but are limited to finite wire or rod length. The more recent concepts of: continuous extrusion with viscous drag, continuous chamber extrusion, continuous extrusion forming, combined hydrostatic extrusion and drawing for fine wire and helical extrusion are compared and their advantages and shortcomings are discussed.
A family of new processes of and apparatus for combining extrusion and rolling, utilizing the friction drag provided by rolling with open chamber extrusion is described. A continuous process, with large reductions and good dimensional control, can be achieved.
