精冲模具与普通冲模不同之处,在于它的模具结构上设有独特的V形齿。对于V形齿和其在冲压过程中的作用以前已有过介绍。但随着加工对象(厚板材料、硬性材料以及内容广泛的复合成形)的增多,有必要再对V形齿具有的功能、条件等因素作些补充介绍,提供一些设计和制造方面的数据资料。 Fine blanking die and ordinary die difference is that it has a unique mold structure V-shaped teeth. For the V-shaped teeth and its role in the stamping process has been introduced before. However, with the increase of the processing object (plate material, hard material and extensive composite forming), it is necessary to make some supplements on the functions and conditions of the V-shaped tooth and provide some design and manufacturing data .
