Description

FIELD OF THE INVENTION

[0001] The present invention relates to a die assembly for the cold drawing of wire both for wet and dry applications.BACKGROUND OF THE INVENTION

[0002] In wire drawing processes, the drawing of wire stock through a drawing-die assembly generates heat during the reduction of the diameter of the wire stock. Lubricants are generally applied to help reduce this heat of drawing.

[0003] Additional methods directed towards reducing this heat of drawing include use of a pressure die prior to a drawing die to increase the amount of lubricant separating the drawing die from the wire during drawing, improving the lubricant properties such as melting point, fat content and viscosity, improving the lubricant carrier by adding polomerized materials in lieu of borax or changing the drawing machine after drawing.

[0004] Examples of equipment applied after the drawing die include using a larger drawing block, improvement of cooling in the drawing block by means such as reducing the d...
