随着我国汽车制造业的蓬勃发展,大型汽车覆盖件模具的设计工作越来越广泛。通过多次尝试,现就大型拉延模设计中,拉延筋的形式提出一点看法。 目前,在设计大型拉延模具时,拉延筋的形式采用得最广泛的是分离式结构,如图1所示。这样的拉延筋,要单独加工成形,然后根据压料面的起伏形状及工件周边形状 With the vigorous development of China’s automobile manufacturing industry, the design of large-scale automobile panel molds is becoming more and more widespread. Through many attempts, now on the large drawing die design, the form of drawbeads make a point. At present, the most widely used drawbead form is the split structure in the design of large drawing dies, as shown in Figure 1. Such a drawbead, to be processed separately forming, and then press the surface of the undulating shape and the shape of the workpiece
