模具以其加工精度稳定,所加工零件形状复杂而著称,在国民经济各工业部门中,几乎都有冲压加工或冲压产品的生产,如汽车、飞机、拖拉机、电机、电器、仪表、铁道、电信、化工以及轻工日用产品中均占有相当大的比重。冲压模具种类繁多,归纳一下,主要有以下几种:冲裁模,弯曲模,拉深模,成形模,复合模等。 Die with its machining accuracy and stability, the shape of the parts processed by complex known, in the various sectors of the national economy, almost all stamping processing or stamping products, such as cars, aircraft, tractors, motors, appliances, meters, railways, telecommunications , Chemical industry and light industry products occupy a large proportion. Stamping a wide range of die, summed up, there are the following: blanking die, bending die, drawing die, forming die, such as composite die.
