Description
This paper shows the influence of the approach zone and bearing part of a die on the longitudinal residual stresses and technological properties of high-carbon steel wire. It has been found that the lowest values of residual stresses on the wire surface occurred in wire drawn in sigmoidal dies with a conical bearing. It also has been proven that the highest number of twists was exhibited in wire drawn in sigmoidal dies rather than concave, convex, or conical dies.
