摘要：

以反挤压工序为研究对象，基于Deform-3D平台，设计了3种不同形式的反挤压凸模，分别进行了数值仿真，并比较了滑套的成形情况以及各凸模结构的磨损深度。为了使反挤压凸模的寿命最大化，通过响应面法建立了凸模工作带高度、凸模前端锥角、凸模顶部球面半径与凸模磨损深度的二阶多项式模型。结果表明：凸模前端锥角对凸模磨损的影响最显著，而凸模顶部球面半径的影响最小；凸模的最优参数为：工作带高度为17.5 mm、前端锥角为19°、顶部球面半径为13.5 mm。最后对凸模的寿命进行了估算，并与实际寿命进行了比较，同时获得了外观较好的万向节滑套。

For the backward extrusion process, three different forms of backward extrusion punch were designed based on platform Deform-3D. Then, the numerical simulation was carried out respectively, and the forming condition of sliding sleeve and the wear depth of each punch structure were compared. In order to maximize the service life of the backward extrusion punch, a second-order polynomial model for the working belt height of punch, the front cone angle of punch, the top spherical radius of punch and the wear depth of punch was established by response surface method. The results show that the front cone angle of punch has the most significant effect on the wear of punch, while the top spherical radius of punch has the least effect. The optimal parameters of punch are the working belt height of 17.5 mm, the front cone angle of 19°, and the top spherical radius of 13.5 mm. Finally, the life of punch was estimated and compared with the actual life. At the same time, the sliding sleeve of universal joint with better appearance was obtained.
