As for the feedstock diameter influence on copper bus bar continuous extrusion,using rigid viscoplastic finite element model,based on the Deform-3D software platform and three-dimensional finite element numerical simulation,two different feedstock continuous extrusion forming processes of expansion metal flow pattern,temperature field,stress field,strain field,as well as torque were obtained.Through theoretical calculations and simulation results of the analysis and comparison,the relationship between feedstock and deformation on continuous extrusion was set up initially,and a theoretical basis was provided on tool and die design.
