Durmapress Founded in 2006,Maanshan Durmapress CNC Machinery Co.,Ltd is located in

 the Maanshan city ,Dangtu County,close to Nanjing Airport. Our geographical position is 

superior and the transportation is very convenient. Our company covers an area of 160 acres 

with the registered capital of 32,000,000 Yuan. We have more than 320 employees, including 

all types of engineering and technical personnel, serving the company R&D, production, and 

customers' service. At the same time, we have our own sales companies in each major and 

medium city. 
Our main products are:CNC Press Brake,Guillotine Shearing Machine,Ironworker,power press ,

and rolling machine these sheet metal processing equipmments.we are using advanced 

technology from German,Japan,and Italy,France and so on.

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
