修理液压机床时,有时会遇到管接头折断在操纵板或操纵箱母体中。我们是采用如下方法修复的。 取一根对角比断管接头通径稍大的高速钢刀块,将其一端磨成四棱锥形(注意锥角不能太大),插入断管接头内孔中约6mm～8mm。用手棰轻轻碰击使其塞紧,然后用活络扳手扳动高速钢刀块,就可将断管接头从操纵板或操纵箱母体中旋出。 When repairing a hydraulic machine, sometimes you encounter a break in the control panel or control box body. We are using the following method to repair. Take a high-speed steel blade slightly larger diagonally than the diameter of the pipe joint, and grind it into a quadrangular pyramid at one end (note that the taper angle can not be too large) and insert it into the bore of the pipe joint by about 6mm to 8mm. Gently tighten it with your hand and tap the high-speed steel blade with an adjustable wrench to unscrew the tube connector from the mast or control box.
