The stress state of the wire drawing is the three-way principal stress state of the two-direction compressive stress and the tensile stress. Compared with the principal stress state in which the three-direction is the compressive stress, the drawn wire is more likely to reach the plastic deformation state. The deformation state of the drawing is a three-way main deformation state in which the two-direction compression deformation is stretched and deformed, which is disadvantageous for exerting the plasticity of the metal material, and is relatively easy to generate and expose surface defects. The amount of deformation of the wire during the drawing process is limited by the safety factor. When the amount of deformation of the ball is small, the number of drawing passes is large. Therefore, multi-pass continuous high-speed drawing is often used in the production of wire.
