Bending machine repair

We are a professional manufacturer of bending machine equipment with over 10 years of industry experience. Today, we would like to introduce to you:

As an important equipment in the metal processing industry, the stability and accuracy of the performance of the bending machine directly affect the quality and production efficiency of the product. Therefore, timely and professional repair is crucial when the bending machine malfunctions or requires maintenance. The following is a guide for bending machines repairing, aimed at helping users better understand and solve common problems in bending machine maintenance.

1.  Preparation work before maintenance

Safe shutdown: Before maintenance, it is necessary to ensure that the bending machine has been completely shut down and all related power sources have been cut off to avoid accidental injury during the maintenance process.
Troubleshooting: Through observation and testing, preliminarily determine the type of fault and possible causes of the bending machine. This helps maintenance personnel locate problems faster and improve maintenance efficiency.

Preparation of maintenance tools: Prepare corresponding maintenance tools and equipment based on the type of fault and maintenance needs, such as wrenches, screwdrivers, micrometers, levels, etc.

2.  Common faults and maintenance methods

Hydraulic system malfunction
Fault manifestations: slow hydraulic cylinder movement, no or insufficient pressure, oil leakage, etc.
Repair method: Check whether the hydraulic pump, hydraulic valve, hydraulic cylinder and pipeline are damaged or blocked, replace damaged parts, clean blocked pipelines, and check the quality and quantity of hydraulic oil. If necessary, replace or supplement hydraulic oil.
Electrical system malfunction
Fault manifestations: motor failure to start, control malfunction, no display screen, etc.
Repair method: Check whether the power lines, motors, controllers, and display screens are damaged or have poor contact, repair or replace damaged parts, and ensure reliable electrical connections.
Mechanical component failure
Fault manifestations: slider shaking, rail wear, mold damage, etc.
Repair method: Adjust the clearance between the slider guide rails, replace severely worn guide rails and sliders, repair or replace damaged molds, and ensure the accuracy and stability of mechanical components.
Decreased accuracy
Fault manifestations: inaccurate bending angle, large deviation in workpiece size, etc.

Repair method: Check and adjust the parallelism and perpendicularity of the workbench, slider, and mold of the bending machine, calibrate the angle and size of the bending machine, and ensure the bending accuracy.

3.  Inspection and testing after repair

Functional inspection: After the repair is completed, check the various functions of the bending machine to ensure that all components operate normally and control accurately.
Accuracy testing: Use standard test workpieces to test the accuracy of the bending machine, including bending angle, workpiece size, etc., to ensure that the repaired bending machine meets production requirements.

Safety inspection: Check the safety protection device of the bending machine to ensure that it is not damaged during maintenance and can function properly, ensuring the safety of operators.

4.  Maintenance precautions

Professional maintenance: The maintenance of the bending machine should be carried out by professional personnel to ensure the quality and safety of the maintenance.
Regular maintenance: Regular maintenance of the bending machine, including cleaning, lubrication, inspection, etc., can extend the service life of the equipment and reduce the occurrence of failures.
Recording and maintenance: During the maintenance process, detailed records of the fault symptoms, maintenance methods, and replaced parts should be kept for subsequent maintenance and troubleshooting.
In summary, the maintenance of bending machines requires the support of professional knowledge and skills. By following the above maintenance guidelines, users can better understand and solve common problems in bending machine maintenance, ensuring the normal operation and production efficiency of the equipment.
