Abstract：

The forming process of electrode terminals was formulated based on the theory of tube upsetting and radial extrusion. Meanwhile the process of cold extrusion forming was simulated by Deform-3D software. The metal flow and filling rules of electrode terminal in the cold extrusion process were revealed through the analysis of metal flow velocity fields. In addition, the load-stroke curve was obtained. Finally the experiment was done according to the parameters of simulation. The result of test made good agreement to the simulation and the whole process feasibility was verified.
