Abstract：

Because of the higher yield and tensile strength of high strength steel parts, more forming force is needed in the stamping production, and the safety factor is enlarged in the design of the die to improve the strength of the structure. For the problem of lacking of experience in the structure design of high strength steel stamping die to cause the increasing of design quality of die and cost, the structure strength of high strength steel complex plate stamping die was analyzed by the finite element method, and the structure of punch was optimized by combining with engineering experiences and topology optimization. Therefore, the rigidity of the die was improved and the mass of the die was reduced by 10%, and the lightweight design was realized. Combined with the simulation technology of stamping, the stress state of key structure of the punch and the characteristics of die structure were synthetically considered, and a new design idea for stamping die of high strength steel was put forward.
