Teach you how to operate the press brake machine

Anhui Lifu Machinery Technology Co., Ltd
Exit the control system program first, and then cut off the power supply. (the machine does not operate at this time)
 
Stroke adjustment, the use of bending machine must pay attention to the adjustment of stroke, before bending, it must be tested.
 
After the equipment is started, it shall be idled for 1-2 minutes, and the skateboard shall be fully moved for 2-3 times. If any abnormal sound or fault is found, the vehicle shall be parked immediately, and the fault shall be eliminated, and the equipment can only be operated after everything is normal.
 
Check the coincidence and firmness of the upper and lower dies; check whether the positioning devices meet the requirements of being processed.
 
The plate of bending machine must be compacted during bending to prevent the plate from lifting and hurting people.
 
When the upper slide plate and each positioning axis are not at the original point, run the program of returning to the original point.
 
It is forbidden to fold over thick iron plate or quenched steel plate, high-grade alloy steel, square steel and plates beyond the function of plate bending machine to avoid damaging the machine tool.
 
If the workpiece or mold is found to be out of alignment during operation, park it for correction. It is strictly forbidden to use the top hand for correction to prevent hand injury.
 
It is strictly prohibited to press the folded sheet material at one end alone. Today, I will teach you the basic operation methods of the bending machine:
 
First, turn on the power, turn on the key switch on the control panel, and then press the oil pump to start, so you can hear the rolling sound of the oil pump.
 
Bending notch selection, generally 8 times the width of the plate thickness notch.
 
Often check the coincidence of the upper and lower dies; check whether the indication of the pressure gauge conforms to the specification.
 
When the machine tool is working, no one is allowed to stand at the back of the machine tool.
 
Have you learned how to operate the bending machine?.
 
It is necessary to cut off the power supply during the die pressing of the plate adjusting material and carry out after the operation is stopped. When the upper die of bending machine goes down to the bottom, a gap of plate thickness must be ensured.
 
One person shall be responsible for the same command during the work, so that the operator and the material feeding and pressing staff can closely cooperate, and the bending signal can be sent only when all the cooperating staff are in a safe position.
 
When changing the start of the variable lower die, no material is allowed to contact with the lower die.
 
Generally, there are electric quick adjustment and manual fine adjustment for the back baffle adjustment, the method is the same as that of the plate shearing machine.
 
Before shutdown, place wood blocks on the lower die under the oil cylinders on both sides to lower the upper slide plate onto the wood blocks.
 
Maintenance of bending machine:
 
Start the machine every day to remove the foreign matters and metal debris on the machine tool and mold. Check whether the mold is firmly installed. The electrical switch, cable, and fasteners are abnormal and loose. Before the maintenance or cleaning of the machine tool, align the upper mold with the lower mold, and then put down the machine until the work is completed.
Safety operation procedures:
 
Before starting the bending machine, check whether the motor, switch, circuit and grounding are normal and firm, and check whether the operation parts and buttons of the equipment are stuck in the correct position. The adjustment of stroke also includes electric fast adjustment and manual gastric adjustment.
Press the foot switch to start bending, the bending machine is different from the plate shearing machine, it can be released at any time, the foot bending machine will stop when it is released, and it will continue to move downward when it is stepped on.
