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