Application and research of piercing device in the side frame outer panel fixture

Zheng Wei;Liu Chunyu;Technology Center,Anhui Jianghuai Automobile Co.,Ltd.;  
A piercing device used in the side frame outer panel fixture of a car was developed,which met the die structure requirement during the design and change process of side frame. The hole of the panel was positioned by positioning pin in fixture,and the profiles were clamped and positioned by clamping device located in the surface of clamping position to ensure the accuracy. The structure and working principle of piercing device were mainly described,the hole added in the side frame during design and change process was realized through the structure designs of cylinder,slippery course,sensors,piercing punch and piercing die. Production practice proves that the piercing device can be effectively used in the side frame outer panel fixture. Therefore,it can meet the production requirement of piercing accuracy,reduce the cost of both model tooling development and design and change,and improve the production efficiency.
