气动冲孔模设计

Design of Pneumatic Piercing Die

重卡车身的大型覆盖件,因功能增加或设计改型,往往会出现一些需要开孔的情况。因大型覆盖件重新开发模具的费用高,所以寻找在焊接夹具体上开孔的方法成为一种简单可行的途径。本文基于侧围外板需要开孔的实例,把气动冲孔模具安装在侧围总成夹具体上,通过简单的气动控制,达到冲孔目的。

Large covering parts of heavy truck body, because the function or design, often there will be some need opening situation. Because of the large covering parts of there development of. die cost is high, so look for a simple and feasible way in the method of welding clamp hole. In this paper, based on the series of side frame outer plate to an opening, the pneumatic piercing die is installed on the side wall assembly fixture,pneumatic control through a simple gas, achieve the purpose of piercing.
