2500mm Plate Bending Rolling Machine , Tank Rolling Machine 3 / 4 Roller

W12-12*2500 W11 3 4 Roller Plate Bending Machine Cone Rolling Machine Tank Rolling Machine Flange Rolling Machine

 

Main Features:

 

The machine has pre-bending function ,can place the plate one time without any position change and achieve the pre-bending and rolling function together.

 

The machine has been imposed with independent operation panel, and has safe-link-lock system. It has the character of high-technology, integrated-function, high-precision and easy-operation, it is ideal plate-rolling equipment and been widely used in all industrial areas for all plate cylinder, arc and cone rolling required fields.

 

The machine is composed by four working rollers , left-right machine body, basement, dump-part, transmission part, sensor part, hydraulic system and electronical system, tempering treatment after rough production, HB220-260.

 

 

The working roller is the main element of the machine under the material of #45 steel , in the finishing treatment procedure ,we use HRC40-45 intermediate

 

frequency quenching to obey strictly all the technical requirement of the working roller produce to guarantee the integrated quality of the machine.

 

The upper roller and the bottom working roller are well act as main drive. The vertical movement of the bottom roller and two side rollers are all controlled by hydraulic ,the vertical movement is digitally displayed and calculated by CNC, levelly automatically, the synchronization precision is ±0.2MM, The dumping equipped also use hydraulic drive ,in the end of up roller ,there are balance structure , can take out the rolled working pieced easily.

 

The basement and machine body are use wielded structure, and strictly done annealing treatment to reduce the inner stress and has enough strength and rigidity and guarantee the normal working when all full-loaded.

 

 

Hydraulic System

 

The hydraulic system can achieve below function: drive the hydraulic-cylinder to make the bottom roller make vertical movement, and drive two side roller make arc movement, control the dumping cylinder to make up-and-down movement.

 

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 electronic control system

 

 

C.1 Structure

 

The system use touth-screen system and has adopt JAPAN OMRON illigent PLC and the input and output module.After all clients’ usage practice ,they have the good stability and strong anti-interference and anti-seismic ability.

 

The sensor adopt high-precision encode to ensure the position precision and monitor all rollers working position. The high voltage parts adopt all the components from China joint famous enterprise has long-term usage and seldom broken character.

 

 

C.2 Control system function

 

A. 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.

 

B. 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.

 

C. control system has warning messenger to timely know what happened for convenient operation and maintenance.
