Common Problems and Troubleshooting Methods of Electro-hydraulic Synchronous Bending Machine

2021-04-22

There are many problems in the use of electro-hydraulic synchronous bending machine, as followsHubei Tri-Ring Metalforming Equipment Co.,LtdJust introduce a more common problem, take a look.

1. First of all, the problem of the slider and the guide rail of the electro-hydraulic synchronous bending machine may lead to the increase of the guide gap due to the long-term up and down movement of the oil cylinder and the vibration of the pressure, which will greatly damage the guide rail and the slider lining plate and seriously affect the accuracy and efficiency of bending.

2. The positioning error of the rear stop material can be affected in many places. First, the screw rod and the smooth rod or the linear guide rail of the rear stop material should be cleaned and lubricated regularly. The rear stop material should be responsible for impurities attached to it. The screw rod and the smooth rod will be damaged for a long time, which will affect the precision positioning of the rear stop material, then the deviation of the parallelism between the linear guide on the rear cross beam and the mold plane is too large. In this case, it is necessary to loosen the shaft synchronous belt, carefully adjust the parallelism tolerance range, and then mount the synchronous belt.

3. The loosening of the oil cylinder of the electro-hydraulic synchronous bending machine and the nut on the connecting rod of the slider will cause the error of the bending angle and the machine cannot find the reference point for recovery.

4. When bending short sheet metal, special attention should be paid to bending in the middle, otherwise the stability and synchronization of the torsion shaft balance system of the bending machine will be affected due to eccentric load, resulting in different bending angles on both sides.

Troubleshooting Method of Electro-hydraulic Synchronous Bending Machine

If the electro-hydraulic synchronous bending machine fails, the following methods can help you troubleshoot.

1. Ask the equipment operator about the operation status of the hydraulic system equipment of the electro-hydraulic synchronous bending machine, including: whether the hydraulic system of the electro-hydraulic synchronous bending machine is working normally; whether the hydraulic pump is abnormal; the time and result of the hydraulic oil detection cleanliness: the cleaning and replacement of the filter element: whether the hydraulic components have been adjusted before the failure: whether the sealing components have been replaced: what abnormal phenomena have occurred in the hydraulic system of the electro-hydraulic synchronous bending machine before and after the failure: what failures have occurred in the system in the past and how to eliminate them need to be understood one by one.

2. Look at the actual working condition of the hydraulic system of the electro-hydraulic synchronous bending machine, and observe whether there are problems with system pressure, speed, oil, leakage, vibration, etc.

3. Listen to the sound of the hydraulic system of the electro-hydraulic synchronous bending machine, such as: impact sound: pump noise and abnormal sound, and judge whether the hydraulic system is working normally.

4. Determine whether the working state of the moving parts of the hydraulic system of the electro-hydraulic synchronous bending machine is normal by touching the temperature rise, vibration, crawling and tightness of the connection.
