图1所示的冲压件(材质08A1),通常需要用2～3副模具进行生产。我们用图2结构的复合模压力机一次行程中即可完成五个工序:落料一冲中孔-拉延外轮廓和翻孔-冲三个偏心孔-压印。该模具还能自动退出废料和顶出工件。从而提高了生产率,降低了生产成本,减轻了劳动强度和保证了安全生产。 The stamping shown in Figure 1 (material 08A1) usually requires 2 or 3 dies. We use Figure 2 structure of the composite die press machine to complete the five processes in one stroke: blanking a punching hole - drawing the outer contour and turn - punch three eccentric holes - stamping. The mold can also automatically exit the waste and the top of the workpiece. Thereby increasing productivity, reducing production costs, reducing labor intensity and ensuring safety in production.
