这里介绍一种比较大型的集冲裁、压筋、切口、冲孔为一体的冷压冲模。被冲产品框板系钢件,见图1,模具结构见图2(工件外形先由另一套模具完成)。这种模具结构代替了通常的二至三套模具。大大提高了工作效率,减轻了劳动强度,降低了模具制造成本,产品符合图纸要求。一、结构特点1.冲内腔凹、凸模结构 Here is a large set of blanking, pressure tendons, incisions, punching as one of the cold die. Washed products frame steel plate, shown in Figure 1, the mold structure shown in Figure 2 (the workpiece shape first completed by another set of molds). This mold structure to replace the usual two to three sets of mold. Greatly improve the work efficiency, reduce the labor intensity, reduce the cost of mold manufacturing, products meet the drawings requirements. First, the structural features 1.
