|
The stamping technology for designing the progressive die of joint-plug-part terminal was analyzed.The feasibility in applying the multi-position progressive die for the production was discussed.The layout design,the characteristics of the die structure and the design of the key parts of the die were introduced.When terminals of joint-plug-part were formed,they would generate bigger forming stress and their numeric value of spring back could not be controlled.The rectangle forming method of positions where the terminal of joint-plug-part contacted with plug and plastic sheathing was discussed.The method was carried out step by step,which could decrease parts' forming stress in parts and spring back.At the meantime,the relevant structure forming male punches were adopted which could not only guarantee part forming but also be easy to machine and modify the dimension of forming positions according to the result of die trial.The die works normally after it is put into production and the quality of parts meets with the specification requirement.
