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
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:
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
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
