Brief Analysis of Common Faults of CNC Bending Machine
2020-12-09
CNC bending machine because of its load is too heavy, the lubrication of the moving parts is not in place, the working environment is more complex and other reasons, are very easy to cause the moving parts wear or strain. In this paper, we analyze the common fault analysis of CNC bending machine:
1. The return of the slider of the CNC bending machine is normal, the fast forward is normal, the manual cannot move down slowly, and the folding plate is weak
(1) Check whether the "three-position four-way" reversing valve that controls the filling control oil circuit works normally. If so, the filling valve is not closed, so that the upper chamber is connected with the filling port of the oil tank and cannot be reduced. The cause of the valve can not work properly is not energized or stuck.
(2) Check whether the filling valve is stuck. If so, please clean the filling valve and reinstall it to make the valve core flexible.
2. The return speed of the slider of the CNC bending machine is too slow, and the return pressure is high
This kind of CNC bending machine fault is mainly the filling valve is not open, this phenomenon is just the opposite of the logical relationship with the above-mentioned fault three, can refer to the solution of fault three for processing.
3. The slider of the numerical control bending machine is not vertical when working, and makes abnormal noise.
This kind of CNC bending machine failure is due to the guide rail use for a long time, the guide rail lubrication is not normal, wear and tear lead to increased clearance. It is necessary to check the wear degree of the guide rail pressure plate and readjust it to meet the required clearance. Depending on the degree of wear to determine whether to replace the guide plate. If the strain is more serious, it needs to be replaced.
(1) The original pressure plate is pasted with plastic. Attention should be paid to the hardness of the pasted plastic and the pasted surface of the guide rail. After shoveling, the pasted surface is guaranteed to be above 85% and the zigzag lubricating oil tank is opened.
(2) the original plate is a metal plug iron. To choose tin bronze plate or ductile iron, the bonding surface grinding machine processing, the connecting bolt should be lower than the bonding surface, and the zigzag lubricating oil groove should be opened.
