Abstract：

Aimed at the possible wrinkles, cracks or non synchronism deformation during the forming process of cylindrical cup, the finite element simulation of the stamping forming and spingback of nickel-coated sheet was carried out based on Dynaform. According to the forming limit and thickness change of parts, the stamping process parameters were adjusted to obtain a better forming effect. The springback analysis of the nickel-coated cylindrical cup was researched. It is found that the springback is small and do not affect the forming condition. On the basis of the simulation analysis, the actual stamping test was carried out. The results are basically consistent with the finite element simulation results, and there is no crack but slightly wrinkle in the flange part. Research shows that simulation analysis can provide the basis for nickel-coated sheet stamping forming and optimization of process parameters, reduce the production cost, shorten the die manufacturing cycle and improve the production efficiency.
