对于细小的零件在大批量冲制时,既要考虑保证冲制件的质量和产量,而又要尽量减少加工工序、节省材料(尤其是有色金属)。然而,要满足这些条件,通常取决于模具的结构和精度。为此,我们改进设计了一副锁闩多工位级进模,见图1所示。 原模是冲裁结构(图2),剖线的部分是废料。它虽然可以通过另外一副弯曲模具加以利用,但由于零件微小,操作困难,而 For small parts in the high-volume punching, it is necessary to consider ensuring the quality and yield stampings, but also to minimize processing steps, saving materials (especially non-ferrous metals). However, to meet these conditions, usually depends on the structure and accuracy of the mold. To this end, we have improved the design of a latch multi-position progressive die, shown in Figure 1. The original model is blanking structure (Figure 2), part of the cross-section is scrap. Although it can be used by another curved mold, but due to the small parts, difficult to operate, and
