Welcome to Visit ANTISHICNC PIPE BENDING MACHINE

What are the common failures and solutions of pipe bending machines?

Pipe bending machine is a kind of mechanical equipment used for curved bending of metal tubes, commonly used in the manufacture of automobiles, airplanes, construction and furniture. However, the use of the process will encounter some common failures that need to be resolved in a timely manner to ensure the normal operation of the equipment and improve productivity.

1.Inaccurate bending angle

This is a common fault, may be due to the mold used for too long or uneven wear of the mold.

Solution: Check the mold, if damaged or worn, timely replacement or repair.

2.Bending process jamming

This may be due to pipe cutting chips or other debris into the pipe bending machine.

Solution: Clean up the inside of the pipe bender to ensure that the pipe is smooth, to avoid the entry of debris.

3.Bender noise

Noise may be caused by loose or unbalanced equipment parts.

Solution: Regular inspection and maintenance of equipment, timely fastening of loose parts, and balance adjustment.

4.Bender hydraulic system failure

Hydraulic system is an important part of the pipe bending machine, involving the supply and control of hydraulic oil. Common failures include hydraulic oil leakage, hydraulic cylinder jamming or uneven operation.

Solution: Check the seals of the hydraulic system, repair or replace the leaking parts, and regularly replace the hydraulic oil.

5.Pipe bending machineelectrical system failure

The electrical system includes control circuits, sensors and motors, etc. Possible failures include motor does not work, poor power contact or control line failure.

Solution: Check the connection and wiring of the electrical system, repair or replace the faulty parts, and ensure that the power supply is stable.

6.Pipe bending machineoperation failure

Operation failure may be due to operator error or equipment failure.

Solution: Train the operator the correct operating methods, equipment troubleshooting and maintenance.

7.Slow pipe bending machine speed

Slow speed may be due to insufficient pressure in the hydraulic system or equipment wear and tear caused by serious.

Solution: Check the pressure of the hydraulic system, adjust or replace the hydraulic pump, while regularly checking the wear and tear of the equipment, timely replacement of worn parts.

Shanghai ANTISHICNC production of pipe bending machine with good quality, high precision, easy to operate, high production efficiency, such as the advantages of the customer’s favorite. For example, the following three-axis oil-electric hybrid servo pipe bending machine CNC3803RES.

CNC3803RES is a hybrid oil-electric pipe bender servo CNC pipe bending machine, by the Y (feed), B (rotary tube), C (bending) 3-axis electrical servo drive. The use of electrical servo drive to avoid the defects of ordinary pipe bender accuracy affected by the oil temperature, suitable for high load, mass production, saving time, labor, space.
