The present invention relates to a disassembling device, and more particularly to a dismounting device for removing a bushing disposed in a hydraulic cylinder.

In general, in the rolling machinery, there are many rolling balance devices that are hydraulically controlled, and need to be pressed and held in the rolling state. Pressure adjustment and position adjustment control are required when installing the rolls for the first time or replacing the new rolls. . For example, the balance device of the roll in the steel rolling mill and the balance device of the upper roll in the straightening machine are all hydraulic control mechanisms, and it is necessary to press and hold the pressure during rolling, and adjust the control in the non-rolling state. Further, in order to prevent variations in the roll gap during rolling, the bearing housings on both sides of the roll have two plungers of the hydraulic cylinders to maintain the roll gap, thereby preventing the rolling of the steel in the rolling due to the change of the roll gap. Bad or product defect.

However, when the hydraulic cylinder of the bearing housing leaks oil, the plunger cannot maintain the gap of the roller, so the oil seal needs to be replaced. Since the copper bush of the hydraulic cylinder has no force applied due to the small gap, the removal operation is difficult. First, to replace the oil seal, first remove the copper bushing above the oil seal. Since the copper bushing is installed in an inner wall groove of the hydraulic cylinder, and the gap between the copper bush and the inner wall groove is narrow, currently There is no suitable tool for assisting in disassembling the copper bushing. The copper bushing can only be destroyed by the drilling technology. Specifically, the fixing ring mounted on the copper bushing is removed first, and then the copper bushing is removed. The plunger is then moved through the crane to the drilling area, the copper bush is broken by the drilling technology, and the copper bush is finally removed. The operation process is quite time consuming and laborious.
