锌基合金是一种软质材料,其硬度仅有HB=120～130。利用硬度较低的材料制造冲裁模,冲裁比其模具本身强度、硬度高的材料,是否可能实现,是否能满足生产需要和维持较高的模具寿命,这是人们所关切的问题。我们研究结果表明,软材料制作冲裁模具,从机理上讲应当与钢冲模有所不同,模具设计、制造、安装、调整、使用等方面也应有相应的差异,它充分地考虑冲压生产
Zinc-based alloy is a soft material, its hardness is only HB = 120 ~ 130. It is a matter of concern that it is possible to manufacture a blanking die with a lower hardness material, to punish a material that has higher strength and hardness than the die itself, whether it is possible to meet the production needs and to maintain a high die life. Our research results show that the soft material production blanking die, the mechanism should be different from the steel die, die design, manufacture, installation, adjustment, use, etc. should also have the corresponding differences, it fully consider the stamping production
