hydraulic press brake

Description

Main application and features

Press Brake is kind of  machine used in cold-forming metal sheet or strip into a desired cross section or structural shape. Normally, with one bending, metal sheet could be bend into cross section. With several bending, it can get complex sectional shaps. It is wildly used in machinery, light industry, automobile, shipbuilding, container, crane, building construction, metal construction, lamppost and electrical post, and so on.
 

Totally European design, streamlined looking
-Frame consists of right and left wall boards, working table, oil tank, slot steel and etc. The stress of the welded parts can be eliminated by vibration. The machine enjoys high accuracy and high     strength and can be transported easily

-Welded structure: the stress of the welded parts can be eliminated by vibration; so this forging press gives high accuracy.
- High accuracy, high efficiency, simple and convenient operation, good performance, favorable price and best service. 

Reliable Hydraulic System

- Adopt integrated hydraulic control system, more reliable and easy for maintenance. The hydraulic system consists of motor, oil pump and valve groups and it is installed at the top of the oil tank.

- Every complete working cycle can be achieved through the control of hydraulic valve.

-Extremely reliable and precise REXROTH or VICKERS or BOSCH valves are used for the regulating circuit.

-There is also a low sound lever pump and a large tank with oil level and temperature gauge on the oil filter.

- Overload overflow protection is outfitted to hydraulic system, which can assure no leakage, and the oil level can be read and seen directly.

Electrical System and Safty Device

-Electrical components are imported or from Sino-foreign joint Venture, in accordance with international standards, reliable safety, long life, good anti-interference ability, a radiation unit is fitted in electrical cabinet.

-Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch, easy to operate.
 

Synchronization Control System:

- PPT series mechanical lever system: A simple, efficient, and accurate mechanical system by means of a torsion bar ensures the parallelism between beams is used for the synchronism.

- SPB series mechanic-hydraulic slide valve system: A complex, efficient and accurate mechanical-hydraulic slide valve is used for the system, with a good synchro-accuracy and protection against one-side loading.
-The worktable adopts particular design, reducing the crowning distortion amount of lower tool effectively. 

-The bending accuracy and consistency of the repeatability are achieved by a simple mechanical system of adjustable depth shops including manual (digit readout) and motorized (LED display) adjustment
