_ 为了提高冲制垫片的质量和装卸模具的方便,我们设计了如图1所示的冲模组合体。特点是其冲切过程是在压料圈对板料加压的状态下进行的,然后用弹力卸料,这样冲出的制件变形小,光洁度较高。本组合体采用外套弹簧,可调整弹力的大小,模具装配时迅速、方便。冲制不同规格的垫片,只需更换件3、5、6、9,模具材料消耗少,制造工艺简单。本结构没有导向机构,靠机床自身
_ In order to improve the quality of the gasket and the convenience of handling the mold, we designed the die assembly as shown in Figure 1. It is characterized in that the blanking process is carried out under the condition that the pressing ring presses the sheet material, and then the elastic material is discharged so that the deformation of the workpiece which is punched out is small and the finish is higher. The combination of jacket spring, adjustable elastic size, mold assembly quickly and easily. Punching different sizes of gaskets, just replacement parts 3, 5, 6, 9, less mold material consumption, manufacturing process is simple. This structure has no guiding mechanism, rely on the machine itself
