摘　　要：在分析现有企业设计开发模具较差基础上,将数值模拟软件Dynaform应用到模具的开发活动中。运用有限元方法和塑性成形技术,对压紧弹簧座零件冲压成形工艺方案进行模拟验证。并采用计算机辅助设计软件Pro/Engineering的自顶向下设计技术,进行模具开发。上述方法可以帮助开发人员快速、准确地进行模具设计,提高生产效率。Based on an analysis of the current die design situation, the numerical simulation software Dynaform was applied to die development. In a compacting spring bracket project, the finite element method and shape forming technology were used to simulate and validate the pressing and forming processes. Top-to-bottom technology of Pro/Engineering next was adopted to design the die. The result shows such die design methods and technologies can help designers develop dies quickly and accurately and improve productivity.
