Welcome to Visit ANTISHICNC PIPE BENDING MACHINE

What are the causes and solutions for overheating of bearings in CNC pipe bending machine?

In the process of using automatic pipe bending machine, sometimes there will be bearing overheating problems, so what are the causes and solutions to cause the automatic pipe bending machine bearing overheating?

1.Pipe bending machine bearing grease is too much or too little.

Solution: Add grease as required (1/3-2/3 of the volume)

2.Pipe bending machine bearing oil quality is not good containing impurities.

Solution: Replace the clean lubricating grease

3.Bearings and journals or end caps with improper (too loose or too tight).

Solution: Too loose can be used to repair the binder, too tight should be car, grinding journal or end cap bore, so that it fits.

4.Bearing bore eccentricity, and shaft friction.

Solution: Repair the bearing cover to eliminate the rubbing point.

5.Pipe bending machine’s motor end cover or bearing cover is not installed flat.

Solution: reassembly

6.The coupling between the motor and the load is not calibrated, or the belt is too tight.

Solution: recalibrate, adjust the belt tension

7.Bearing clearance is too large or too small.

Solution: Replace the bearings with new ones

8.Motor shaft bending.

Solution: correct the bending machine motor shaft or replace the rotor

Shanghai ANTS Machine Equipment Co. specializing in the production of CNC pipe bending machine, hydraulic pipe bending machine and other equipment. Shanghai ANTISHICNC of the production of pipe bending machine with high quality, high precision, easy to operate, well received by customers around the world. For example, the following oil-electric hybrid automatic pipe bending machine CNC5005RET-RBE.

CNC5005RET-RBE is a five-axis oil-electric hybrid servo bending machine, by the Y (feeding), B (tube), C (bending), X (demolding), F (side auxiliary push) 5-axis electrical servo drive. with precision servo cornering, bending accuracy of 0.01 ° feeding accuracy of 0.01 mm. With precision servo corner, bending accuracy of 0.01 °, feeding accuracy of 0.01 mm. the use of electrical servo drive to avoid the defects of the ordinary bending machine precision affected by the oil temperature and the C-axis bending due to the increase in the temperature of the hydraulic oil, resulting in bending accuracy problems, greatly improving the accuracy of bending the workpiece, saving time, manpower, space, suitable for high-load, high-volume production.
