Abstract：

This article analyses the limit of the existent production method of the CPU fin,makes a new process plan and designs a set of unique dies that make use of the transfer unit to send the material.This paper introduces the application of the transfer unit to the cold forging forming process of the CPU fin.The structure and action theory of the transfer unit and the design process that the die cooperating with the transfer unit and the press are deduced.So the whole process of the CPU fin production have been finished smoothly.At the same time,the integration of the mechanization and electrization are realized.The structure increases the velocity,saves the cost and gets the more economic benefit.The experience is beneficial to the designers.
