Abstract
The impact of friction factor, thickness of the cold extrusion, semi-cone angle and other factors on cold extrusion was analyzed. Various process parameters were set and optimized. Cold extrusion process of hollow pieces was simulated by DEFORM-3D software. Through the simulation of the virtual velocity field, strain field, stress field, load - stroke curve and metal deformation process, the flow velocity of the metal and the deformation of the workpiece were studied. The metal flow routes and the parts that are easy to wear in die were gained. The above research results provide valuable references for the processing of hollow pieces.
