摘要:

由于高强钢零件有着更高的屈服、抗拉强度,在冲压生产时需要更大的成形力,因此,在设计模具时会放大安全系数,使结构强度得到提升。针对目前高强钢冲压模具结构设计经验不足,造成模具设计质量增大、成本增加的问题,采用有限元的方法,对高强钢复杂板冲压模具凸模的结构进行了刚强度分析,结合工程经验与拓扑优化技术,将凸模结构进行了优化,使模具整体的刚度提高并且模具质量减轻了10%,实现了轻量化设计。结合冲压成形模拟仿真技术,将凸模关键结构的应力状态与模具结构特点综合考量,提出了新的针对于高强钢冲压模具的设计思路。

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.
