Research on Processing Technology of Upsetting and Extruding Forming Concave Dies for Conical Part
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.
