一、问题的提出 我公司电视机冲压件是从82年下半年开始国产化的,零件图纸由日方提供,我公司负责模具设计、加工、冲压等生产任务,所有冲压件需经严格检验和试装样机的试验,合格后方能投入批量生产。 在试装样机中发现:有些带M3翻边螺孔的比较关键的冲压件(如TRS架、天线支架等),螺纹是用国内传统工艺M3丝锥加工的,在装配中发生严重滑牙现象(用气动螺丝刀装配,冲压件M3阴螺纹在锁紧时螺牙全
First, the question put forward Our TV stamping parts from the second half of 82 domestic localization, parts drawings provided by the Japanese side, our company is responsible for mold design, processing, stamping and other production tasks, all stamping parts subject to rigorous testing and Test prototype equipment, qualified before they can put into mass production. In the prototype installation, it was found that some of the more critical stampings (such as TRS frame and antenna bracket) with M3 flanging screw holes were machined with the traditional taps made in China M3, and serious sliding teeth occurred in the assembly Pneumatic screwdriver assembly, stamping parts M3 female thread in the lock thread full
