Abstract：

The characteristics and difficulties of the different styles for pipe hole punching technology were described.The forcing situation during the process of pipe hole punching and its effect on the pipe distortion were analysed.The necessity and design methods of the pipe hole punching,clampping and possible reverse distortion were explained.The units combination of the designing structure of pipe hole punching and the key parts manufacturing were introduced.Many advantages,such as simple structure,low manufacturing cost,easy assemble,suitability for many kinds of items,short lead time and wider applications were also introduced.By using the die,the application range of pipe hole punching process was expanded and the adaptability of the die was enhanced.
