Abstract:
1. A die for drawing associated wire products, comprising: at least a first die portion having first and second ends, the at least a first die portion having a cavity fashioned at least partially interior to the at least a first die portion for use in drawing an associated wire; wherein the cavity extends from the first end of the at least a first die portion to the second end; wherein the associated wire has an associated wire diameter d, wherein the associated wire travels through the cavity along a first axis; wherein the cavity comprises: wherein the first drawing contour, the first bearing region, the second drawing contour, the second bearing region, and the non-drawing contour are located within one die; wherein the first bearing region is located between the first drawing contour and the second drawing contour, wherein the second bearing region is located between the second drawing contour and the non-drawing contour; wherein the first drawing contour reduces the wire's first-contour-entering cross-sectional area by an amount ranging from about 1.5 to 16.2%; wherein the second drawing contour reduces the wire's second-contour-entering cross-sectional area by an amount ranging from about 2% to 6%.
