图1所示零件的成形、翻边、弯曲、冲孔几道工序由一套如图2的复合模一次完成。本冲模无卸料机构,从而大大简化了模具结构,方便了设计和制造。但冲孔后的零件紧箍在两冲孔阳模10上,造成卸料困难。取下后的零件出现挠曲变形。我们对现有模具作了点滴改进,顺利冲出了合格零件。根据冲裁间隙对冲件尺寸精度影响的规律,我们注意到我国冲裁模的间隙表,由于受
Figure 1 shows the parts forming, flanging, bending, punching several processes from a set of composite mold as shown in Figure 2 completed. The die-free discharge agencies, which greatly simplifies the mold structure, to facilitate the design and manufacture. However, the punched parts are tightened in two punch male molds 10, which makes it difficult to unload materials. After removing the parts appear flexural deformation. We made some improvements to the existing mold, successfully out of qualified parts. According to blanking clearance hedges dimensional accuracy of the rules, we noticed that China blanking die clearance table, due to
