Structural characteristics of fully automatic CNC pipe bending machine
1. The pipe bending machine adopts a touch screen and CNC module, with conversational operation and easy program setting;
2. The bed structure is stable and not easily deformed;
3. Each file can set 16 bend angles, and the memory can store 16 sets of files;
4. Equipped with slow positioning function, the bending angle is stable, and the repeatability accuracy reaches ± 0.1 °;
5. Error messages are displayed on the screen to assist the operator in immediately troubleshooting;
6. Provide self-developed coordinate conversion bending pipe processing values, software can be purchased and installed on a desktop computer for editing and calculation.
Operation method of CNC fully automatic pipe bending machine
1. First, connect the power supply, turn on the switch on the control panel, and then start the oil pump, so that you can hear the sound of the oil pump rotating. (At this time, the machine is not moving)
2. Travel adjustment, it is necessary to pay attention to adjusting the travel before use, and it must be tested before bending. When its upper mold descends to the bottom, there must be a gap of plate thickness. Otherwise, it will cause damage to the mold machine. The adjustment of the itinerary also has electric quick adjustment.
3. When selecting a bending groove, it is generally necessary to choose a groove with a width 8 times the thickness of the board. If bending a 4mm sheet metal, a slot of about 32 should be selected.
4. Rear gear adjustment generally includes electric quick adjustment and manual fine adjustment, using the same method as a shearing machine.
5. Press the foot switch to start bending. The CNC bending machine mold is different from the shearing machine, it can be released at any time. Release the foot and stop, and continue to descend while pressing.
Common problems and solutions of fully automatic pipe bending machine
Possible faults and troubleshooting methods:
1. Automatic pipe bending machine malfunction: After the piston rod extends a certain length and shakes the handle, the rod extends and retracts.
Cause: The fuel plug was not loosened. Loosen the fuel plug.
Exclusion method: The outlet valve port in the pump body is not sealed, and the outlet valve steel ball is not round. If there is garbage in the oil, clean the engine oil and replace the steel ball.
2. Fault: Oil leakage at the piston rod of the large and small pumps.
Cause: Damaged sealing ring.
Exclusion method: Replace the sealing ring in the spare parts bag.
3. Automatic pipe bending machine malfunction: oil leakage at the switch.
Cause: The pressure ring inside the switch is too loose.
Exclusion method: After removing the limit screw and switch, tighten the pressure ring.
4. The top rod cannot be pushed out and cannot work.
Cause: Poor sealing of the steel ball inside the switch, failure to firmly secure the steel ball at the top of the switch, or steel balls falling off.
Exclusion method: Replace the steel ball and tighten the switch. If there is no steel ball, a steel ball should be added.
5. Oil leakage at the top of the top rod
Cause: The sealing ring at the top of the piston rod is damaged
Exclusion method: Replace the 14 × 2.4 O-ring seal (self provided)
6. Automatic pipe bending machine malfunction: insufficient oil suction of large and small pumps
Cause: There is garbage or insufficient oil on the filter screen inside the filter;
Exclusion method: Unscrew the part, clean the mesh body with gasoline and fill it with oil.
7. Automatic pipe bending machine malfunction: cracked mold installation hole;
Reason for occurrence: There is lateral load when the mold item is taken out, such as: the position of the bent workpiece is not aligned when it is bent again.
Exclusion method: Check if the positions of the two supporting wheels are symmetrical, apply oil to the joint between the supporting wheels and the workpiece, and position it correctly for the second bending.
8. Fault: Pick up pump, also known as overflow pump or return pump
Cause: The steel ball of the oil outlet valve cannot be reset normally.
Exclusion method: Extend the action rod so that there is pressure on the plunger pump. Then, tap the handle seat a few times with a Lang head to reset the valve ball.
