半轴套管法兰盘是带法兰的深孔件,深孔加工难度大,在锻造中挤压深孔的方法具有典型意义。我厂引进西德哈森克勒佛公司6300吨机械锻压机时,附有一套半轴套管法兰盘挤压模,尔后我们经改进后又制造了三套,已生产一万余件。现将模具的应用及其改进情况介绍如下。一、锻件设计1.锻件图设计(1)深孔的端部不能挤压成通孔(见图1)。根据机加工工艺要求,端部采用顶针孔定
Half-shaft bushing flange is a deep hole with flange pieces, deep hole processing difficult, deep forging extrusion method has a typical significance. When our factory introduced 6,300 tons mechanical forging press of West Germany Haase Keller Buddha Company, we had a set of semi-shaft casing flange extrusion die, then we made three sets after improvement and produced more than 10,000 pieces. Now the application of the mold and its improvement are described below. First, the forging design 1. Forgings design (1) the end of the deep hole can not be squeezed into the through-hole (see Figure 1). According to machining requirements, the end of the thimble hole set
