Common problems and troubleshooting methods of fully automatic pipe bending machines

Possible faults and troubleshooting methods:

1. Fault: The hydraulic cylinder of the fully automatic pipe bending machine extends to a certain height and shakes the rocker rod, causing the neck rod to extend and retract. Cause: The oil plug was not loosened, and the oil plug was loosened. Exclusion method: The oil extraction valve port of the pump casing is not sealed, and the steel ball of the oil outlet valve is not round. If there is waste in the oil, clean car oil should be replaced, and the steel ball should be removed and replaced.

2. Fault: Oil leakage at the hydraulic cylinders of the large and small pumps of the fully automatic pipe bending machine. Cause: Damaged sealing ring; Troubleshooting method: Replace the sealing ring in the accessory bag.

3. Fault: Oil leakage at the switch of the fully automatic pipe bending machine; Cause: The pressure ring inside the switch is too loose; Exclusion method: After removing the lowest value screw and switch, tighten the pressure ring.

4. Fault: The top rod of the fully automatic pipe bending machine lacks force in the mold and cannot work. Cause: The sealing of the steel ball inside the switch is not good, and the top of the switch is not firmly pressed against the steel ball or the steel ball bursts out; Exclusion method: Replace the steel ball tightening switch. If there is no steel ball, a steel ball should be added.

5. Fault: Oil leakage at the top of the top rod of the fully automatic pipe bending machine; Cause: The sealing ring at the top of the hydraulic cylinder is damaged; Troubleshooting method: Replace the 14 × 2.4 O-ring (spare)

6. Fault: Insufficient oil removal from the large and small pumps of the fully automatic pipe bending machine; Cause: The filter inside the filter has attached waste or insufficient remaining oil; Troubleshooting method: Twist open part number 12, clean the mesh with diesel and fill it with oil.

7. Fault: The template installation hole of the fully automatic pipe bending machine is cracked; Cause: There is a side load when the template item is released, such as: the bent product workpiece is not properly adjusted when it is bent again; Exclusion method: Check if the two supporting wheels are symmetrical, apply oil to the mating area between the supporting wheels and the product workpiece, and adjust the position of the second bending.
