The top plate of shock absorber is an asymmetric workpiece with complex structure, and the forming of this kind of workpiece has been a difficulty point in the stamping process. Therefore, according to the quality problems in the top plate of shock absorber produced by the enterprise, the forming mechanism of the top plate workpiece for shock absorber was studied by simulation software Dynaform, the causes of the quality problems for the top plate of shock absorber were analyzed, and the solution process scheme was put forward. Then, the asymmetrical structure forming was transformed into symmetrical structure forming by the forming method of two pieces in one mold. During the workpiece forming, the deformation of material was controlled by the mutual constraint resistance of material deformation, and the deformation sequence of workpiece was controlled by the forming mold structure, which improved the forming quality of workpiece and the life of mold. Furthermore, the reasonable suggestions were put forward for the design and manufacture of the forming mold for the top plate of shock absorber. The enterprise production shows that the optimized production process and forming mold not only reduce the springback amount for the top plate of shock absorber after forming, but also improve the dimensional accuracy, the geometric shape accuracy and the production efficiency for the top plate of shock absorber, and reduce the production cost.
