100Ton X 2500mm hydraulic metal bending machine hydraulic press brake from Durmapress

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 
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 
Consist of motor, oil pump and valve groups 
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.


1.Main Features
1) hydraulic drive, the machine at both ends of the cylinder placed in the slider, direct

 drive sliding work.
(2) the use of mechanical block structure, stable and reliable.
(3) slider stroke maneuver fast tune, manual fine-tuning, counter display.
(4) the use of all welded structure, with sufficient strength and rigidity.
(5) The slider synchronization mechanism uses the torsion axis forcing synchronization.
(6) wedge-shaped deflection compensation mechanism to ensure a higher bending 

accuracy
