In order to improve the production efficiency and change the original process of ball head tie rod for automobile suspension by turning, a multi-station cold upsetting process was proposed. Based on software DEFORM-3D, a finite element model was established to simulate the plastic forming process of ball head tie rod, and the influences of the technological parameters such as pre-forming punch entry angle α, pre-forming die fillet R1, final forming die fillet R2 and final forming die entry angle β on the forming process of ball head tie rod were studied. Then, the orthogonal tests were carried out, and the reasonable combination of process parameters was obtained by taking the load of mold and the damage value of part in the forming process of ball head tie rod as the optimization goals. The results show that on the premise of ensuring the forming quality of workpiece and the life of mold, it has a significant effect on reducing the die load and the workpiece damage with the pre-forming punch entry angle α of 30°, the pre-forming die fillet R1 of 12 mm, the final forming die fillet R2 of 3 mm and the final forming die entry angle β of 60°. Furthermore, using the optimized parameters for trial production, the forming quality of workpiece is better, which verifies the credibility of the simulation results and effectively guides the design work of process designers.
