机械零件上毛刺的去除,已成为机械工业中十分关心的问题。因为毛刺不仅会影响机器的寿命,而且严重时会导致机械损坏或电器零件的短路,造成重大的设备损坏等事故。下面以电表中的蜗杆为例,谈谈我们用电解法在蜗杆上去除毛刺的应用实践。蜗杆是电表中不可缺少的传动件,表面质量要求很高。齿面若有较小的毛刺或光洁度不够,在运行时都会导致齿跳或轻载不转等弊病。过去用机械法去毛刺,不仅不能彻底清除齿面上的毛刺,齿面光洁度达不到要求,而且费工大。现在我们用电解法对蜗杆去除毛刺和抛光,其工效比机械法提高5.2倍,去毛刺的效果也好,表面光洁度能提高1～2级。
The removal of burrs on mechanical parts has become a matter of great concern in the machinery industry. Because glitches not only affect the life of the machine, but also in serious cases can lead to mechanical damage or electrical parts short circuit, causing major equipment damage and other accidents. Below the worm in the meter, for example, talk about our use of electrolytic method to remove burrs on the worm application practice. Worm is an indispensable electric meter transmission, surface quality requirements are high. If there is a small tooth flank or surface finish is not enough, will lead to tooth jump in the run-time or light load does not turn and other ills. In the past using mechanical deburring, not only can not completely remove the burr on the tooth surface, tooth surface finish less than required, and costly. Now we use electrolysis method to remove burrs and polishing worm, the work efficiency than the mechanical method to improve 5.2 times, the effect of deburring Ye Hao, surface finish can improve 1 to 2 levels.
