中文摘要：通过分析锥形件镦挤整形凹模破裂的原因,对该凹模的毛坯锻造工艺以及热处理工艺进行了有效改进，给出了更加合理的毛坯锻造工艺参数，以及毛坯预处理工艺和整形凹模的热处理工艺，从而大大提高了整形凹模的使用寿命，保证了锥形件镦挤整形工序的顺利进行。
英文摘要： Through analyzing rupture cause of upsetting and extruding forming concave dies for conical part, its forging process and heat treatment process was improved, the more reasonable forging process parameters, the preconditioning process for the blank and the heat treatment process for the concave dies were obtained. The using life of the concave dies greatly enhances, the conical part's upsetting and extruding forming process is smooth.
