图1所示零件,材料:紫铜。按常规的冲制方法,每种零件至少需要两套模具(冲孔落料模+翻边模或者落料拉深模+冲底模),并应分别下料。我们根据零件的形状特点和使用情况,在不影响其使用性能的前提下,对零件原设计尺寸作了一些修改,设计制造了一付多工序复合模,将大件的落料、拉深、冲底、小件拉深、冲底五道工序复合在一起,使一次冲压能同时得到两种零件各一个。 Figure 1 parts, materials: copper. According to the conventional stamping method, at least two sets of molds are required for each part (punching blanking + burring or blanking and drawing dies + blanking die), and the blanks should be separately blanked. We make some modifications to the original design dimensions of the parts on the premise of not affecting the performance of the parts according to the shape characteristics and usage of the parts. We designed and manufactured a multi-process compound die to cut, draw, Rushed at the end, small pieces of deep drawing, red bottoming five processes together, so that a stamping can get two parts at the same time.
