The principle of high quality hydraulic press brake is mainly when the wire is energized with the coil will produce gravity on the pressure plate,
when the gravity can achieve clamping between the pressure plate and the base, so as to achieve the bending of the sheet, the specific operation tutorial is as follows:
1. First, switch on the power supply, turn on the switch on the control panel, and then start the oil pump,
so that you can hear the rotating sound of the oil pump. (The machine does not move at this time)
2, stroke adjustment, use must pay attention to adjust the stroke, must be tested before bending.Its upper die down to the bottom must ensure
that there is a plate thickness clearance. Otherwise it will cause damage to the mould machine. Stroke adjustment is also electric quick adjustment.
3, bending notch selection, generally choose the plate thickness of 8 times the width of the notch. For bending 4mm sheet metal, choose about 32 notches.
4, the rear stopper adjustment generally has electric quick adjustment and manual fine tuning, the method is the same as the shearing machine.
5, step on the foot switch to start bending, CNC bending machine mold and shearing machine is different, can be loosened at any time, loosen the foot will stop, continue to step down.
