Product Description

Hydraulic Sheet Metal Press Brake Machine

1. High precision, Wide application
2. EU CE Certification
3. CQC, ISO9001: 2008
4. High performance,
5. Easy to operation.

The whole structure of the hydraulic press brake:
– Welded structure: The stress of the welded parts can be eliminated by vibration; So this forging press gives high accuracy.
– Frame: Consists of right and left wall boards, working table, oil box, 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.
– High accuracy, high efficiency, simple and convenient operation, good performance, favorable price and best service.
1. Hydraulic system:
– 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
2. Protective fence and the safety interlock:
– 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.

3. Synchro control system:
– Slide syncho system: Adopt steel torsion bar synchro system, simple in structure and high in accuracy
– 2 ends of slide has 2 synchro fork which make, The system uses upper die compensation to improve the brake precision.
– Adopt upper die compensation to improve the brake precision
4. Sectional RAM Clamp Bars:

-Separate sectional clamping bars are supplied as standard equipment in order to securely fasten short dies, as well as standard length tooling. Unique crown correcting device is standard.
5. Advance technology and procedures:
– This metal machining tool is a kind of steel torsion bar synchro press brake. -Electronic control of back gauges and RAM stroke, data displayed and manual setting
– Process of cylinder and sealing component:
Cylinder: No. 45# steel treated, inner holes fine machined and extruded.
Valve rods: No. 45# steel treated, nickel and phosphorous coated outside.
