Abstract：

For the vehicle flange connector, based on its structural characteristics, a six-station cold forging process scheme was proposed, and the forming process of each station was modeled and analyzed by Deform-3D. The results show that this scheme can obtain the flange connector with a completely filled appearance, but there are material folding defects. Thus, two improved schemes based on the original scheme were proposed and simulated in turn, and the grid streamline change diagrams of the improved schemes were analyzed. At the same time, the forming loads of the two improved schemes were compared. The results show that the two improved schemes can solve the problem of material folding. When the improved scheme 1 is adopted, the forming load is relatively smaller, which is more conducive to reducing the mold load and increasing the mold life. The actual mold test shows that the parts produced according to the improved scheme 1 are consistent with the simulation results, the forming is complete, there are no defects such as cracks and folds etc., and the process is reliable. Thus, this optimization method has a certain promotion effect on the development of multi-station forging technology.
