1、概述以往,制造图1所示带有内翻边迥转体零件的加工工序是比较繁复的。一般要经过多次钳工和车工的辅助性劳动才能完成。有些工厂虽略有改进,但仍属传统性工艺。即先采用落料模冲制圆片坯料,再由拉深模拉深成有底的筒件,然后在车床上按尺寸挖去底部。最后辊辗出另一端的翻边。现采用新颖结构的模具,用圆筒形坯料可以在一次冲压行程中获得所需制件。制件的坯料尺寸是d_0=72mm,h_0=45.5mm。
1, Overview In the past, the manufacturing process shown in FIG. 1 with a swivel part with swivel flange is more complicated. Generally after several fitter and turner work to complete the auxiliary work. Although some factories slightly improved, but still a traditional process. That is, blanking die blanks are used first, and then the die is drawn by the die to a bottomed cylinder, then the bottom is dug by the size of the lathe. The last roller out of the other side of the cuff. Now the new structure of the mold, the use of cylindrical blanks in a stamping stroke to obtain the required parts. The blank size of the part is d_0 = 72 mm, h_0 = 45.5 mm.
