增设附加凹模的简易精冲工艺与模具研究

The low-lost precision piercing technology & the mould research of extra die added

介绍了一种增设附加凹模在普通压力机上实现精密冲裁的新方法和模具结构。

The new method and the mould structure to achieve precision piercing on plain presses with adding extra die have been introduced.With analysis of the die's inherent mechanism to realize precision piercing,determining of the main technology parameters such as clearance,corrective allowance and die thickness and the calculation of the main technology force and the main problem of the production has been expounded,hence a referrence to the stamping and the die design of the same type products.
