| 摘 要： | 详细分析了活塞尾锻件模锻工艺方案及关键技术特点，提出了闭塞制坯、终锻成形及切边工艺方案，并用Deform-3D软件进行有限元模拟分析。模拟结果显示，只要在两工步间合理分配变形量，即可顺利成形锻件；同时，斜底凸模较平底凸模更容易制坯。该工艺方案可行，能保证生产时工艺的稳定性。

| Abstract: | In this paper,according to the characters of the piston tail part,the die forging process and the key technology are analyzed in detailed.Then,the two steps forging scheme is designed-one for making billet and the other for end shape.The models are simulated using Deform-3D software.The results of the simulation show: Only when the quantity of deformation is proper divided in two steps,the part can be forged successfully.The program can be a feasible scheme and can be used to guide the production. |
