我们曾接到一批石棉垫片(图1)的生产任务,从零件的形状看,最合理的工艺方法是在冲床上利用复合冲模一次完成。但这种工艺方法,我们条件不具备。所以根据我们的具体情况,设计了如图2的划切垫片装置。实践证明,效果非常好。 We have received a number of production tasks of asbestos gasket (Figure 1), from the shape of the parts, the most reasonable process is to use the punch on the use of composite die at a time. However, this process, our conditions do not have. Therefore, according to our specific situation, designed as shown in Figure 2 cut gasket device. Practice has proved that the effect is very good.
