Troubleshooting common problems of a Rotative Head All Electric Tube Bender is crucial for maintaining its optimal performance and ensuring smooth production processes. As a supplier of Rotative Head All Electric Tube Benders, I’ve encountered various issues over the years. In this blog, I’ll share some insights on how to diagnose and resolve these common problems.

1. Bending Angle Inaccuracy
One of the most frequent issues users face is inaccurate bending angles. This can be caused by several factors.
Mechanical Wear and Tear
Over time, the components of the tube bender, such as the bending die and the clamping mechanism, may experience wear. The bending die is responsible for shaping the tube, and if it is worn, it can lead to inconsistent bending angles. To check for die wear, inspect the surface of the die for signs of excessive scratching or deformation. If the die is worn, it should be replaced.
The clamping mechanism also plays a vital role in ensuring accurate bending. If the clamps are loose or not properly adjusted, the tube may move during the bending process, resulting in inaccurate angles. Check the clamping force and ensure that the clamps are tightened correctly. You can use a torque wrench to achieve the recommended clamping torque.
Electrical and Control System Issues
The electrical and control system of the tube bender is responsible for controlling the bending process. If there are issues with the sensors or the control software, it can lead to inaccurate bending angles. Check the sensors to ensure they are functioning properly. Clean the sensors and make sure they are correctly positioned.
The control software may also need to be updated. Outdated software can cause glitches and inaccuracies in the bending process. Contact the manufacturer to obtain the latest software version and follow the instructions for installation.
2. Tube Surface Scratching
Scratching on the tube surface is another common problem. This can affect the appearance and quality of the final product.
Die and Tooling Issues
The bending die and other tooling components can cause scratching if they are not properly maintained. The surface of the die should be smooth and free of any burrs or rough edges. Regularly clean and polish the die to prevent scratching.
In addition, the lubrication of the die and the tube is essential. Lack of lubrication can increase friction between the die and the tube, leading to scratching. Use a high – quality lubricant and apply it evenly on the tube surface before bending.
Tube Handling
Improper tube handling can also cause scratching. When loading and unloading the tube, be careful not to drag it across rough surfaces. Use appropriate lifting equipment and ensure that the tube is properly supported during the bending process.
3. Machine Vibration
Excessive machine vibration can not only affect the accuracy of the bending process but also cause premature wear of the machine components.
Unbalanced Rotating Parts
The rotating parts of the tube bender, such as the bending head, may become unbalanced over time. This can cause vibration. To check for unbalance, use a vibration analyzer. If unbalance is detected, the rotating parts may need to be balanced. This can be done by adding or removing weights from the rotating components.
Loose Fasteners
Loose fasteners can also cause vibration. Check all the bolts and nuts on the machine regularly and tighten them if necessary. Make sure that all the components are securely attached to the machine frame.
4. Hydraulic System Problems (if applicable)
Although Rotative Head All Electric Tube Benders are mainly electric, some models may have a hydraulic system for certain functions.
Leakage
Hydraulic fluid leakage is a common problem. Check the hydraulic hoses, fittings, and seals for any signs of leakage. If a leak is detected, replace the damaged component immediately.
Low Hydraulic Pressure
Low hydraulic pressure can affect the performance of the hydraulic system. Check the hydraulic pump and the pressure regulator. Make sure that the hydraulic fluid level is correct and that there are no blockages in the hydraulic lines.
5. Motor and Drive Issues
The motor and drive system are the power sources of the tube bender.
Overheating
Overheating of the motor can be caused by overloading, poor ventilation, or a malfunctioning cooling system. Check the motor’s operating temperature regularly. If the motor is overheating, reduce the load or improve the ventilation. Clean the cooling fins and ensure that the cooling fan is working properly.
Motor Failure
If the motor fails to start or stops unexpectedly, it may be due to electrical problems, such as a blown fuse or a faulty motor controller. Check the electrical connections and the motor controller. If necessary, replace the damaged components.
6. Maintenance and Preventive Measures
Regular maintenance is the key to preventing these common problems.
Scheduled Maintenance
Create a maintenance schedule for the tube bender. This should include tasks such as cleaning, lubrication, and inspection of components. Follow the manufacturer’s recommendations for maintenance intervals.
Operator Training
Proper operator training is essential for the correct use of the tube bender. Train operators on how to operate the machine safely and correctly. Provide them with training on troubleshooting common problems so that they can handle minor issues on their own.
Spare Parts Inventory
Maintain an inventory of essential spare parts. This can reduce downtime in case of component failure. Keep spare parts such as bending dies, sensors, and electrical components in stock.
In conclusion, troubleshooting common problems of a Rotative Head All Electric Tube Bender requires a systematic approach. By understanding the possible causes of these problems and taking appropriate preventive measures, you can ensure the reliable operation of the machine and improve the quality of your products.
