Technical parameter of Hydraulic press brake with E21 125T/2500 mm
The Main feature
• The whole machine is in sheet plate welded structure, entire welded frame ,with internal stress eliminated by vibration aging technology ,high strength and good rigidity of machine.
• Double hydraulic oil cylinder is applied for upper transmission, provided with mechanical limit stopper and synchronous torsion bar, typical of stable and reliable operation, as well as high precision.
• Electrical control and manual fine-tuning mode are adopted for distance of rear stopper and stroke of gliding block ,and fitted with digital display device ,easy and quick in use.
• Slider stroke adjusting device and back gauge device: electric quick adjusting ,manual micro adjusting ,digital display ,easy and quick in use.
• The machine has inch, single, continuous mode specifications, commutation, dwell time can be controlled by time relay.
• Safety railing ,door-open power -off device.
• Mechanical synchrony torsion bar, to keep the left -right balance movement.
• Mechanical wedge partial compensation structure.
• Japan NOK original imported master cylinder seals.

Hydraulic System
Hydraulic system is from Bosch -Rexroth, Germany.
When the oil comes out from the pump, all the way into the pressure cylinder first presses the sheet material, and another routing time relay controls the delay to enter the left cylinder upper chamber for about 2 seconds. The oil in the lower cylinder of the left cylinder is forced into the upper cylinder upper chamber and the right cylinder lower chamber. Oil back to the tank. The return stroke is reversed by the solenoid valve
