What is the principle of a bending machine and how is it used?

Principle: The working process in which the pressure generated by the hydraulic system is transmitted through the mold, and finally the desired shape of the material is obtained.
How to use the bending machine:
1. First, turn on the power supply, turn on the key switch on the control panel, and then press the oil pump to start, so that you can hear the rotation sound of the oil pump.
2. Stroke adjustment, the use of the bending machine must pay attention to the adjustment of the stroke, and be sure to test the car before bending. When the upper die of the bending machine goes down to the bottom, there must be a gap of plate thickness. Otherwise, it will cause damage to the mold and the machine. The adjustment of the stroke also has electric quick adjustment and manual fine adjustment.
3. For the selection of the bending notch, it is generally necessary to select a notch with a width of 8 times the thickness of the plate. For bending 4mm sheet, you need to choose a notch of about 32.
4. The rear gauge adjustment generally has electric quick adjustment and manual fine adjustment, the method is the same as that of the shearing machine.
5. Step on the foot switch to start bending. The bending machine is different from the shearing machine.
