我厂生产的几种液压挖掘机阀体上所共有的压盖(图1),其外形和各部尺寸都完全一致,只是厚度不相同,但每种批量都很小。所以若每种都使用一付钢制模具冲压,那不仅不经济,更重要的是不能满足生产周期、新产品试制的需要。根据锌基合金冲裁模和钢皮模的特性,我们设计制造了一种蒙钢皮的锌基合金落料模,其结构简单,制造方便,寿命长。尤
I produced a few types of hydraulic excavator valve body common gland (Figure 1), the shape and size of the ministries are exactly the same, but the thickness is not the same, but each batch is very small. So if each use a pair of steel mold stamping, it is not only uneconomical, more importantly, can not meet the production cycle, new product trial needs. According to the characteristics of zinc-based alloy blanking die and steel die, we designed and manufactured a zinc-based alloy blanking die with a steel structure, which has the advantages of simple structure, convenient manufacture and long service life. especially
