Abstract：

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.
