A press brake can be described by basic parameters, such as the press brake force or press brake tonnage and the press brake working length. Additional parameters include the press brake amplitude or press brake stroke, the distance between the press brake frame uprights or side housings, distance to the backgauge, and press brake work height. The press brake upper beam usually operates at a speed ranging from 1 to 15 mm/sec.
There are several types of press brakes as described by the means of applying force: mechanical press brake, pneumatic press brake, hydraulic press brake, and servo-electric press brake.
In a mechanical press brake, energy is added to a flywheel with an electric motor. A clutch engages the flywheel to power a crank mechanism that moves the ram vertically. Accuracy and speed are two advantages of the mechanical press brake.
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.

8. Hydraulic system of cnc press brake/hydraulic press brake/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 press brake/hydraulic press brake/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.

The CNC hydraulic press brake is equipped with new-style man-machine CNC system, which is developed by ourselves. It is easy to master and it may greatly improve the users' productivity. Main feature: The press brake adopts whole steel welded structure. And it has enough intensity and rigidity. Ram synchronization during the stroke is controlled by a mechanical torque synchro system, which is steady and reliable. And the stroke of the ram is adjusted in the inter cylinders. The ram stroke and the back gauge can be adjusted by motor and manual adjustment. And it can be displayed by counters. A hydraulic system is used for the machine. A feeding valve is used to speed up the ram travel to save energy. The operations of the machine are realized by the hydraulic valves A gear pump is used to reduce the noise of the machine, which can achieve the environmental standard. The dies are made of carbon steel, which have good rigidity and durable. And they are equipped with adjusting wedges of high precision. Word-class elements are used for the electric system of the machine, which is safe and reliable. There are multi catenation and interlock in the electric system, which can avoid mistakes. The machine is equipped with fully safety guard and emergency stop which can ensure the safety of the operators. The position of the back gauge can be accurately adjusted by operating the touch screen. The stroke of the ram can be accurately adjusted by operating the touch screen. The CNC system can auto calculate the bending angle. Operators can edit machining programs in advance. And the system will process as the programs require.
