Abstract：
|
|
The four side plant PCM(Pre-Coated Metal)punch dies of family 2P aircondition tank and corresponding technology were designed.The PCM punch process relative to general punch process was pointed out.The project of three punch processes for side plant and the structure characteristics and working principle of dies were analyzed.The key points of manufacturing of main parts and measures adopted in the corresponding parts of punch dies in order to prevent the PCM layer from injuring were introduced.The structure of dies is reasonable,the technology is reliable,the manufacture period is shortened,and the cost is lower.The products have good appearance quality,the production efficiency is increased,and the production cost is reduced.
