为了适应工作需要,我们把 Y5120A 插齿机改装成专用插斜齿轮的机床。因电压不正常,正在工作的插齿机只要一停电,斜齿面就要被插坏,有时还碰坏插刀,经济损失很大。我们经过反复摸索,找到了存在原因:突然停电时,原油路上二位四通电磁阀不能完全关闭油的回路,工作油缸因失去 In order to meet the needs of our work, we modified the Y5120A gear shaper into a special plug-in bevel gear machine. Due to the voltage is not normal, the gear shaper is working as long as a power failure, the bevel gear to be plugged bad, and sometimes also hit the bad knife, a great economic loss. After repeated exploration, we found the existence of reasons: a sudden power outage, the two-way solenoid valve on the crude oil can not completely shut down the oil circuit, the work of the cylinder because of the loss
