W12 Double Pinch 4 Roll Plate Bending Machine Sheet Bending Tools

W12 Double Pinch 4 Roll Plate Bending Machine Sheet Bending Tools

Description:

The sheet 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 rollsup-and-down movement is controlled by hydraulic drive. The up-and-down

displacementof 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

machinefor 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

Character:

The rolling machine is computer-controlled four roller bending rolls machine with the

pre-bending function. After the plate loaded, no need to change into another side edge

for the prebending and rolling.

The machine four rollers has been produced by forge, hardening and tempering treatment.

HB220-260 with good mechanical properties, high rigidity, high in anti-abrasion, good for

high-load working and long working lifetime.

Our working roller side gear use ball gear, small in friction and reduce the active power lose

and save the energe.

The bottom roller and side rollers movement are controlled by computer. Automatic-leveling,

digital display screen, the synchronization accuracy ±0.2MM, high in rolling precision and

easy in operation.

The machine down roller, side roller can do one-side inclining, and can make synchronization

movement in inclined position for a better cone rolling working.

The machine has moveable operation table for a convenient worker operation and the touch

screen has the position for the three rollers, easy for you understand the position.

The machine control system adopt Japan OMRON company intelligent PLC programmable

control with fault diagnosis and operation fault intelligent judgment, the all parts inspection

for the machine, logic treatment , power-off memory.

High-voltage parts use SUZHOU electronic, long working lifetime and less fault.

The hydraulic valve in the hydraulic system use Taiwan brand, the valve is casting runner ,

large oil flow ,small resistance, less heat and reliable.

The pipes in all hydraulic system use fast joint, new-technology used in metallurgical mines,

in the connectors, there are reliable seal to ensure no leak out in the hydraulic system.

The hydraulic system has absorption and return oil filter to ensure the clean of the hydraulic

system. And also air filter to guarantee the hydro-cylinder normal absorption and water

evaporation, and in the system there are double-way security protection equipment to ensure

the system safe.

The dumping gear will force on the dumping hydro-cylinder, the head can incline and stand-up,

convenient for take-off the working pieces.

The end of the working roller has balance equipment which will be responsible for the working

roller balance when the dumping gear is working.

Advantages:

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

Control System Function:

To control the working roller synchronization movement automatially

Control the bottom roller vertical movement synchronization, the synchronization

precision is ±0.2MM.

Control two side rollers synchronization movement,the synchronization precision is ±0.2MM.

display real-time date and all rolling information and plate-rolling information.

The bottom roller’s two side has real time date.

The two sides of side rollers has real time date.

control system has warning messenger to timely know what happened for convenient operation

and maintenance.

WUXI JINQIU MACHINERY CO.,LTD was founded in June 1969. it is located in No.99Qianluo road

Qianqiao town Huishan district Wuxi city. It is at Wuxi Vocation park. It mainly produces hydraulic press brake,

hydraulic shear, CNC sheet V grooving machine, allotype surface quick forming machine, CNC hydraulic turret

punching machine and other series products. It is one of the backbone enterprises in the domestic forging

industry with 40 years’ history.

The company covers an area of 62000 square meters with over 50000 square meters construction area.

It have advanced production equipments with imported large CNC gantry milling machine, imported large

CNC boring and milling machine, 100T carriageway and a series of iconic devices.

Company’s excellent design team can make personalized products according to the user’s demands which

to maximize customer value and optimize customer cost performance. Meanwhile, the company have always

stood in the forefront of technological innovation, continued to explore the “JQ”brand products widely and deeply,

and also attached great importance to the research cooperation. it has established long-term cooperative relations
