Feauture of tandem press brake:
1, The tandem press brake uses 2 sets of WC67Y series press brakes of the same type, with duple linked synchronous device;
2, The two machines of the tandem press brake can be used together for processing longe workpiece, and also can be used individually, therefore improve the productivity of manufacture;
3, Deflection compensation unite installed on the top die of the cnc tandem press brake, in order to guarantee the precison of processed work piece;
4, The tandem press brake has mechanical back gauge, torque, with synchronous valve control;
5, The cnc tandem press brake uses cnc system to control back gauge, travel of upper slip ram.
Hydraulic press brakes operate by means of two synchronized hydraulic cylinders on the C-frames moving the upper beam. Servo-electric press brakes use a servo-motor to drive a ballscrew or belt drive to exert tonnage on the ram.
Pneumatic press brakes utilize air pressure to develop tonnage on the ram.
Until the 1950s, mechanical press brakes dominated the world market. The advent of better hydraulic press brakes and computer control press brakes have led to hydraulic press brake machines being the most popular.
Pneumatic and servo-electric press brake machines are typically used in lower tonnage applications. Hydraulic press brakes produce accurate high quality products are reliable, use little energy and are safer because, unlike flywheel-driven press brakes, the motion of the ram can be easily stopped at any time in response to a safety device i.e. a light curtain.
Features of CNC Hydraulic press brake
1,The cnc hydraulic press brake is steel welded structure;
2,The cnc hydraulic press brake eliminates stress by vibration.
3,The cnc hydraulic press brake has high mechanical strength, and exceptional rigidity.
4,The cnc hydraulic press brake uses hydraulic top-drive, steady and reliable.
5,The cnc hydraulic press brake has mechanical stop and steel torsion bar to maintain synchronization and high precision.
6,Thecnc hydraulic press brake electric adjustment, manual fine adjustment, and digital display for backgauge distance and stroke of up ram.
7,Deflection compensation unit installed on the up die or on the down die if the operating pressure is bigger than 250T .
8. Hydraulic system of cnc hydraulic press brake:
- Adopt integrated hydraulic control system, more reliable
- Consist of motor, oil pump and valve groups
- Be installed at the top of the oil box, which can assure that the cylinder is always full of oil when the slide is moving down at high speed
- Complete working cycle can be realized through the control of hydraulic valve.
- The working pressure at the right side of the wall board can be adjusted by the remote adjustment valve
9. Protective fence and the safety interlock of cnc hydraulic press brake :
- Protective fence and the safety interlocker to ensure the operation safety. Power supply switch that is set in the electric box will be automatically turned off when the box's door is opened or the fence is turned up. Protecting barrier with safety interlocker is mounted on the back of the machine. Another, there are travel limit protection and foot pedestal mounted emergency off switch.
