我厂接受了一大批生产批量仅要几十件到几百件,产品比较规则,零件质量要求较高的任务。对于这些产品,我们除了进行全面的工艺分析外,还将在一定范围内尺寸和形状类似的产品进行分组分类。其中有一部分是厚度在2毫米左右长形零件软材料的冲裁(图1—a)和厚度在0.5毫米左右圆零件硬材料的冲裁(图1—b),需要用复合冲裁模保证产品的质量。但是如果每一个零件,都要用一件复合模加工,则是不经济的。 I plant a large number of production received only a few dozens to hundreds of pieces, the product more rules, the higher quality parts of the task. For these products, in addition to a comprehensive process analysis, we will also be within a certain range of products of similar size and shape classification. Some of them are blanking (Fig. 1-a) of a soft material of an elongated part with a thickness of about 2 mm and blanking of a hard material of a circular part with a thickness of about 0.5 mm (Fig. 1-b) Quality of products. But if every part, to use a composite die processing, it is not economical.
