What causes the motor of a pipe bending machine to overheat?

While overheating of the motor during pipe bending machine operation usually doesn't affect its lifespan and is generally not a concern for most customers, it can severely damage the motor. To determine if the hydraulic pipe bending machine motor is burnt out, first check for a burning smell, open the junction box, remove the terminal blocks, and use a multimeter to check for a three-phase short circuit. For inter-turn short circuits, use a bridge test and a megohmmeter to measure the grounding resistance; check if the hydraulic pipe bending machine motor temperature is very high. Hydraulic pipe bending machines are a widely used shearing device in machining, capable of shearing steel plates of various thicknesses.

When a leak occurs in the hydraulic system of a pipe bending machine, reduce the number of oil pipe joints and use integrated control valves to prevent system leaks; during reversing, extend the reversing time as much as possible to reduce hydraulic shock and mechanical vibration; the pipe bending machine requires regular inspection, maintenance, and timely handling to prevent leaks.

Sometimes, the hydraulic system of a pipe bending machine may overheat during operation. Internal causes include improper system design, such as mismatched components, excessively narrow pipe channels, numerous bends, small bending radii, and insufficient oil tank capacity. External causes include improper oil quantity leading to hydraulic system problems.

1. The pipe bending machine uses a touchscreen and CNC module, with interactive operation and easy program setting.

2. The machine bed structure is stable and not easily deformed.

3. Each setting allows for 16 bending angles, and the memory can store 16 sets of files.

4. It has a slow-speed positioning function, ensuring stable bending angles and a repeatability accuracy of ±0.1°.

5. Error messages are displayed on the screen to help the operator troubleshoot immediately.

6. It provides a self-developed coordinate conversion function for pipe bending processing values; the software is optional and can be installed on a desktop computer for editing and calculation.
