Sheet 4 Roll Plate Rolling Machine , 4 Roller Bending Machine





1. used to coil plate into different sharps such as cylindrical form, conic form and arc, it

adopted Japan hydraulic technical

2. Top roller can do vertical and level motion, up and down, parallel translation is display

3. Upper roll can move in vertical and level include pre-bending function

3. Adopted many points to lubricate Universal Plate Rolling Machine

4. Mechnical, hydraulic, electricity all system set over loading protect device

5. Fitted quality CNC system fault check itself automatically, error give an alarm, mistake

protection and so on pipe bener

6. Adopt hand switch button box easily operate Universal Plate Rolling Machine

7. Simple foundation equipment, it can move to operate 3 and 4 Roller four roller plate

rolling machine, heavy steel plate roller, metal sheet manufacturer




The 4 roller plate rolling machine has pre-bending function for plate edge, and can bend roll

the plate one time without any thing re-rolling with combined procedure or prebending and

bending roll into shape. The upper roller is the main drive roll, the down roller and two side

rolls up-and-down movement is controlled by hydraulic drive. The up-and-down displacement

of the down and side rollers are controlled by computer. Automatic leveling, display by screen,

high synchronization precision ±0.2MM.Turnover bearing body dumping and reset is done through

hydraulic transmission. The upper roll end has balance equipment to be convenient take of the

rolled cylinder and working pieces.

There are moveable independent operation table for easy moveable operation. The machine has

been equipped with security linked equipment. It is ideal bending roll machine for all kinds of metal

working industry like energy, transportation ,petroleum, chemical, shipping-building, boiler with high

technology, full function, high precision and easy in operation character.

The machine is equipped by four working rollers, left-right machine shaft, basement, cone rolling

equipment, dumping parts, transmission part and relate sensor section, hydraulic system and

electrical system.





Through the Electro-hydraulic directional control valve ,can control the bottom roller up-and-down

movement and also the arc movement of two side rollers. Through hydraulic-control non-return

valve ,the working roller can stay at any position.

Dumping cylinder’s return circuit has one-way throttle valve, can adjustment suitably for the

working structure speed.

The all hydraulic system has reasonable design , reliable in working and equipped with high-precision

oil and oil filter to ensure the clean of the hydraulic system oil. The pipe system is reasonable placed,

convenient in operation and flexible in action to guarantee the non leakage of the system.

The 4 roll plate bending machine is the easiest one, thanks to a frame designed to satisfy every

kind of needs. Advantages are various :

1. Pre-bending is highly reduced because the material gets pinched by in between the two central rolls.

2. Working can be made in one only pass, following the steps here below:

  • Squaring
  • Pre-bending
  • Bending
  • Closing pre-bending

3. The plate is fed into the machine horizontally thanks to the support of the lower roll (B) with the

side roll (D).

4. The plate is squared thanks to the position that the side roll (C) takes.

5. The space to the limit of the machine reduces to one side only, thanks to the possibility of

squaring and bending in one only step.

We advise a 4 roll plate bending machine :

6. For a high and massive production

7. For the possibility to control by NC

8. For the possibility to make conical bendings


Structure :


Totally European design,streamlined looking,frames of our machines are fabricated,

welded steel (ST-52).

Roll shafts, materials and bearings used in production are European quality. Also the torque

limit of the machines is very high.

NC playback and CNC graphic control systems are available as optional accessory.

The main structure of the equipment includes upper roller, lower roller and horizontal movement

mechanism, supporting mechanism,

main drive mechanism,downturn system, left and right machine frame, chassis and balance

mechanism, hydraulic and electrical control systems.

The model MH has both the upper and the lower roll powered with hydraulic motor and planetary

gear box.
