Precautions and operation methods for use of plate cnc press brake bending machine
Precautions for use of plate cnc press brake bending machine
- Strictly observe the safety operation regulations of Primapress machine tool workers, and wear labor protection articles as required.
- Before starting, carefully check whether the motor, switch, circuit and grounding are normal and firm, and check whether all operating parts and buttons of the equipment are in the correct position.
- Check the coincidence and firmness of upper and lower moulds; Check whether the positioning devices meet the requirements for processing.
- When the upper sliding plate and each positioning axis are not at the original point, run the return to the original point program.
- After the equipment is started, it will run without load for 1-2 minutes, and the upper sliding plate will move for 2-3 times at full stroke. If there is abnormal sound or fault, it should stop immediately to eliminate the fault. It can only work after everything is normal.
- During operation, one person shall command in a unified way, so that the operator can closely cooperate with the feeding and pressing personnel, and the bending signal can be sent only when the cooperating personnel are in a safe position.
- The sheet material must be compacted during bending to prevent it from warping and hurting people.
- The power supply must be cut off when adjusting the sheet material and pressing the die, and the operation must be stopped.
- When changing the opening of the variable lower die, no material is allowed to contact the lower die.
- No one is allowed to stand at the rear of the machine tool during operation.
- It is strictly forbidden to press the folded plate at one end.
- If the workpiece or die is found to be out of alignment during operation, it shall be stopped for correction. It is strictly prohibited to correct by hand during operation to prevent hand injury.
- It is forbidden to bend super thick iron plates or quenched steel plates, high-grade alloy steels, square steels and plates beyond the performance of the plate bending machine to avoid damage to the machine tool.
- Frequently check the coincidence of upper and lower moulds; Whether the indication of the pressure gauge meets the requirements.
- Stop the machine immediately in case of abnormality, check the cause and eliminate it in time.
- Before shutdown, place wood blocks on the lower mold below the oil cylinders on both sides to lower the upper sliding plate onto the wood blocks.
- Exit the control system program first, and then cut off the power supply [2].
Operation method of plate cnc press brake bending machine
- First, turn on the power, 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 turning, but the machine does not execute action at this time.
- For stroke adjustment, pay attention to the stroke adjustment when using, and test it before bending. When the upper die descends to the bottom, there must be a clearance of plate thickness, otherwise the die machine will be damaged. The stroke adjustment is also electric quick adjustment.
- For the selection of bending notches, generally, 8 times the width of the plate thickness shall be selected. If the 4mm sheet is bent, a notch of about 32 should be selected.
- The adjustment of rear stopper generally includes electric quick adjustment and manual fine adjustment, and the method is the same as that of plate shears.
- Step down the foot switch to start bending. The mold of the NC bending machine is different from that of the plate shearing machine. It can be released at any time. Release the foot and stop, and then continue to move down [4].
