摘　　要：基于弹性阀座壁薄、材料难加工的特点,介绍了级进模的结构以及制造要点,针对弹性阀座的机械加工和冲压加工工艺进行了对比,研究出组合级进模制造弹性阀座,分析了级进模冲压加工所产生的误差,给出了级进模的误差分析公式,从而大大提高产品的质量和生产效率,实现自动化生产。On the basis of the characteristic of the thin wall and the manufacturing difficulty of the elastic seat, structure and manufacturing features of progressive die were introduced. Comparison was made between machinery and stamping of elastic seat. Compound progressive die for elastic seat was developed and lbrogressive die error analysis formula was provided. The product quality was thus greatly improved and manufacturing automation was realized.
