提出了厚板台阶孔二次冷压锻造的新工艺方案。利用DEFORM-3D软件对两步成形过程进行了有限元分析。得到速度阴影等值线。根据数值模拟的工艺参数，设计了实验模具，有限元分析结果与实验数据吻合较好。
An new technological scheme for a two-step cold press forging of step holes in a thick metal sheet was proposed . Finite element analysis on the two-step process is carried out by using DEFORM-3D. Velocity shade contours are obtained. The study shows that the technique can form step holes in thick sheet metal and increase their strength, According to the numerical simulation’s process parameter, an experimental die is designed, the FEA results are in good agreement with the experimental data.
