 Electro-hydraulic servo CNC bending machine, Sheet metal bending machine, bridge bending machine

This series of electro-hydraulic servo CNC bending machine is a kind of high-end CNC bending machine using electro-hydraulic proportional synchronization technology, with proportional valve, grating ruler and so on. With good synchronization accuracy, strong anti-partial load capacity. The frame adopts steel plate welding as a whole, the appearance is decent and standard, with enough strength and rigidity, the work is stable, safe and reliable, easy to operate, can achieve the ideal bending effect.

The upgraded VERSION WL-67K electro-hydraulic servo CNC bending machine is a commonly used mechanical equipment in sheet metal. Many customers want to know how to effectively deal with failure as soon as possible.

The upgraded VERSION OF WL-67K electro-hydraulic servo CNC bending machine fault most due to the use of guide rail for a long time, guide rail lubrication is not normal, wear resulting in increased clearance. This type of fault requires troubleshooting, maintenance or replacement of faulty components, and troubleshooting.


Upgrade version WL-67K electro-hydraulic servo CNC bending machine due to its load, moving parts lubrication is not in place, the working environment is more complex and other reasons bending machine, are easy to cause moving parts wear, strain. If the strain is serious, replace it. Failure of retaining shaft driver and servo motor, failure of upper computer control system.

The size of rear stopper is inconsistent at both ends (size head) : the error at both ends is small, within 2mm. Check and confirm that X1/X2 mechanical transmission structure has no fault, and the error can be eliminated by adjusting the stopper finger. To choose tin bronze plate or ductile iron, laminating surface grinding machine processing, connecting bolts should be lower than the laminating surface, open a zigzag lubrication groove.


Daikin laser for you to analyze the upgrade version of WL-67K electro-hydraulic servo CNC bending machine common mechanical failure and maintenance:


1. The slide block is not vertical when working, making abnormal sound. It is necessary to check the wear degree of the guide pressure plate and adjust it to meet the requirements. A, the original pressure plate is pasted plastic, pay attention to choose the hardness of pasted plastic, and the pasted surface of the guide rail, after scraping, the upgraded version WL-67K electro-hydraulic servo CNC bending machine to ensure that the pasted surface is above 85%, open the zigzag lubrication oil groove; B, the original pressure plate is metal plug iron. Readjust to the tolerance of parallelism and reinstall the synchronous drive.

3. There is no movement of the rear material shaft


The failure of rear axle transmission may be due to the separation of the drive shaft from the synchronous belt wheel, key bar or the synchronous belt slip.


4. The connection between the cylinder and the slider is loose


The loose connection between the cylinder and the slider may cause incorrect bending Angle or the machine cannot find the reference point


If the mechanical transmission structure has no fault (such as: bearing, ball screw, rail, drive wheel, belt, etc.), troubleshoot. Depending on the degree of wear to determine whether to replace the guide plate.
