摘要：

为解决一种空间异形三通半管零件在传统冲压成形过程中的成形失效、表面质量不佳及成形效率低等问题，根据零件特征，结合AutoForm有限元仿真软件，对该零件的传统冲压成形过程进行了数值模拟并优化，通过分析其成形失效原因，提出了采用充液拉深成形工艺代替传统冲压成形工艺，并对该零件的充液拉深成形过程进行数值模拟并优化。通过对两种工艺成形效果的对比，验证了工艺改进的可行性。最后，在800 t双动充液成形液压机上，分别采用两种成形工艺试制零件，验证了数值模拟的可靠性和实际的工艺改进效果。通过成形工艺的改进，有效地解决了成形失效问题，表面质量和成形效率得到了显著提升，零件成形效果满足工艺需求。

In order to solve the problems of forming failure, poor surface quality and low forming efficiency for a spatial special-shaped three-way half pipe part in the traditional stamping process, according to the characteristics of part and combining with finite element simulation software AutoForm, the traditional stamping process of part was numerically simulated and optimized. Then, through the analysis of forming failure causes, a hydroforming process was proposed to replace the traditional stamping process, and the hydroforming process of the part was numerically simulated and optimized. Furthermore, the feasibility of process improvement was verified by comparing the forming effects of the two processes mentioned above. Finally, two forming processes were used to trial-produce parts on 800 t double-acting hydraulic press, and the reliability of numerical simulation and the effect of actual process improvement were verified. Thus, through the improvement of forming process, the problem of forming failure is effectively solved, the surface quality and forming efficiency are significantly improved, and the forming effect of part meets the process requirements.
