摘要：

以管坯镦锻和径向挤压理论为基础，制定了电极端子冷挤压成形工艺。运用有限元软件Deform-3D进行了冷挤压成形过程的模拟，通过对金属流动速度场分析，揭示了电极端子冷挤压过程中金属流动规律和充填规律。另外，得到了载荷与凸模行程的关系曲线。最后参照模拟的工艺参数进行了工艺实验，实验结果与模拟结果吻合，验证了整个工艺过程的可行性。

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.
