At present, machinery, automobiles, equipment and other industries have higher and higher quality requirements for the required products, and precision has become an increasingly important factor in the production and assembly of parts. In order to reduce costs, it is necessary to produce these parts efficiently and in large quantities, and it is necessary to reduce the processing procedures of the parts as much as possible. In the past, stainless steel heads needed to be repaired by a spinning machine after being cold stamped to meet the requirements of the head diameter. This greatly reduces the production efficiency of the head and increases the production cost. The main content of this paper is to optimize the die parameters and stamping process to make the stainless steel head directly meet the requirements of the diameter of the head after cold stamping.

　　The finite element software Marc is used to simulate the stamping process of the dish head, and the springback law of the smallest wall thickness, stamping load, and head diameter of the dish head under different blank holder forces is studied, and finally the best blank holder force is obtained; Under different convex and concave die gaps, the minimum wall thickness, punching load, and the springback law of the head diameter of the dish-shaped head are obtained, and the best convex and concave die gap is obtained; the influence of the various parameters of the drawbead on the head diameter springback is studied by orthogonal experiments Finally, the optimal drawbead parameters are obtained through range analysis and variance analysis, and the influence of each parameter of the drawbead on the resilience of the head diameter is studied. Finally, the mold is processed according to the best drawing bead parameters and the gap between the convex and concave molds, and field experiments are performed for verification.
