Automatic pipe bending machine is out of order. How should we deal with it?

Nov 29,2022
Automatic pipe bending machine overall rigidity is good, stable work, safe and reliable, easy to operate, through the pipe bender mold CNC system and hydraulic system coordinated control, to obtain the ideal bending effect. However, we need to understand the inevitable faults encountered in the process of use in order to solve them in time.

1. The main shaft of the automatic pipe bender is faulty. Due to the use of adjustable speed motor, the main box structure is relatively simple, prone to failure of automatic pull rod, automatic speed regulating device.
2, automatic tool change device (ATC) failure. In the automatic tool changing device, more than 50% of the faults of the automatic pipe bender are related to the automatic tool changing device, which are mainly shown as: tool library movement, positioning error, unstable clamping of the manipulator, unstable clamping of the manipulator, large operating error, etc. In case of major failure, the tool change action is stuck, forcing the bend to stop working.
3. Feeding transmission chain failure. Because the CNC bending machine guide rail generally uses rolling friction pair, the main reason for the feed chain is that the moving parts can not move, the work is interrupted, the positioning accuracy decreases, the reverse clearance increases the mechanical crawling, this part of the fault can be adjusted by adjusting the motion pair to adjust the motion precision of the moving parts.
4. Failure of supporting accessories. The main reasons of automatic pipe bender are: cooling device, chip removal device, guide rail shield, coolant shield, main cooling constant temperature tank, hydraulic tank, etc., failure seriously affects the normal work of CNC pipe bender.
5. It is used to detect the pressing failure of the travel switch at the moving position of each axis. In order to ensure the reliability of automatic pipe bender, the travel switch is tested for many times. This is also a more common symptom, I hope you can analyze after understanding, know to solve the fault.
