在机械维修过程中,常常会出现轴(或杆)类零件弯曲的情况。传统的方法是用机械压力校正,但效果不够明显,且易损伤维修件表面层。这里介绍一种火焰自然校正法。 我车间某刨齿机的传动蜗杆齿根部分弯曲,造成加工工件达不到工艺要求。我们采用了火焰校正法对弯曲部份的受拉侧(凸侧)进行局部加热到400℃～ In the mechanical maintenance process, often appear shaft (or rod) parts bent. The traditional method is to use mechanical pressure correction, but the effect is not obvious enough, and easy to damage the surface of maintenance parts. Here is a natural flame method. Some of my workshop gear driving worm gear root bending, resulting in processing of workpieces can not reach the process requirements. We use the flame correction method on the curved part of the pull side (convex side) for local heating to 400 ℃ ~
