Characteristics of wire drawing process
Sep 10, 2018

The stress state of wire drawing is two to the three-direction stress state, which is always tensile stress, and it is easier to reach the plastic deformation state than the three-direction compressive stress in the main stress state. The deformation state of drawing is two-direction compression deformation, which is a three-direction deformation state, which is unfavorable to the plasticity of metal material, and it is more prone to produce and expose surface defects. Wire drawing process of the road deformation is limited by its safety factor, the number of road deformation is smaller than the number of draw more, so in the production of wire is often used multi-pass continuous high speed drawing.
