            II.The main structure of the device
            The device can pre-bend the sides of plate,feed steel plate just one time,don’t need to return can to pre-bend the sides of plate,and roll the plate. The up roller is the main drive roller,the down rollers and side roller use hydraulic drive to do elevate movement. And controlled by computer to up or down,horizontal adjust automatic,show by screen,the synchromesh accuracy attached ±0.2mm. Turnover and resume of flip-bearing used hydraulic to drive. Installed balance system on the ends of up roller,so it’s easy to unload workpiece. Adopt mobile independence operator table,so can operator at any time and any place,the machine has safety interlock device. For a world it has high technology,overall function,high accuracy and easy to operator. So it’s the model rolling machine,it’s the first choice in energy,transport,fossil oil,chemical,shipbuilding,steel and some other industries.
            This machine composed of four working rollers,left and right rack of machine,base board,rolling rhombus tube function,turnover part,device part,sensor part,hydraulic system,electrical system and so on.

            i.Mechanical part
            Working roller is the main spare of the device. And the material choice steel 42CrMo,and stand some standards very serious to make it. Then can ensure the comprehensive mechanical performance.
            The base board and rock as the main parts of device,use wield structure. Do anneal treatment comply with arts standard,this can eliminate internal stress,so it has enough strength and steel performance. It can work on full load state.
            Up roller is the main drive roller,the motor work with the help of gear box to drive it. The output spindle of motor installed braking device,so it can ensure fixed position accuracy. All above these ensure the whole body has enough strength,the main joints connector with key and melt,so it’s easy to install and repair.
            The down roller and two side rollers do elevate movement drive by the ends oil vat. The ends bearings use axis adjustable roller bearings. Elevating
            synchronization controlled by computer. The turnover side of up roller installed turnover oil vat,the ends of up roller installed balance mechanism,so it’s easy to unload the workpiece.

            ii.Hydraulic system
            The hydraulic system of this device has the following functions: drive oil vat do elevating movement,drive the sides rollers do inclined elevating movement,and drive the turnover oil vat do elevating movement.
            With the help of electrical liquid commutate valve to control the down rollers to do elevating movement and the sides rollers to do inclined elevating movement. So the working rollers can stop on arbitrary position.
            The circuit of turnover oil vat installed one-way throttle valve,it can adjust the speed of executive mechanism.
            The hydraulic system design reasonable,work good and allocate high accuracy filter to ensure oil clear. The system pipeline arrange regularity,operator easy,act flexibility. All above these ensure the system no percolation.
            The main valves of hydraulic system choose from Taiwan. The pump,filter,motor and seal element choose from native and foreign famous company,so all these have high performance and quality. All components done test,sift,lower the breakdown do our best.

            iii.Electrical system
            A.Structure
            Electrical system display by touch screen and adopts Omron product(includes input and output models. this system has some advantages as the example high ability to prevent interference,long life,prevent shock,work  steady and so on.
            Sensor adopts high accuracy optical encoder to ensure position accuracy and monitor the position of all rollers. The main components of high voltage part adopt SIMENS products or some foreign products. So it’s has some advantages like as long life,no breakdown time long.
            B.The function of control system
            a)Automatic control working rollers do synchronization movement
            Control the down roller elevating synchronization,the accuracy attached ±0.2mm.
            Control two side rollers elevating synchronization,the accuracy attached ±0.2mm
            b)Show all actual time data and information of rolling plate.
            Two ends absolutely position show at real time of down roller.
            Two ends absolutely position show at real time of side rollers.
            The ends gradient show at real time of down roller
            The ends gradient show at real time of sides rollers
            c)The control system provide alarm message,it’s help to do some cooperate and maintain.

            III.Main characters of the device
            i.This machine is four rollers rolling machine controlled by computer. It can pr-bend the ends of plate,
            feed plate and don’t return. So it pr-bend the ends of plate and roll shape just one time.
            ii.The four working rollers do forge and material treatment,HB220~260,combination mechanical
            performance is good,the strength is high,friction endurance is high,so it suit high load work and have long life.
            iii.The work roller end bearing adopt roller bearing,so it has small friction coefficient,decrease reactive
            power loss,reduce energy consumption.
            iv.Lifting move of bottom roller and sides rollers controlled by computer,automatic leveling,show as
            figure at the same time. The synchronized precision ±0.2mm. Plate bending high-precision,easy to use
            v.This machine has removable console,the operator more convenient to use,touch-screen display the
            location of three work rollers,so that the operator at a glance. 
            vi.The machine control system using Japan‘s OMRON intelligent high-speed PLC programmable logic
            controller,the system has a fault diagnosis,intelligent judge error,machine tool parts of the monitoring,processing logic,memory,such as power protection; the system with anti-jamming capability Strong,long service life,earthquake,etc. stable.
            vii.The sensors of bottom and side rollers has high accuracy ,to ensure position accuracy and monitor
            the roller position.
            viii.The components choose from SIMENS of the strong power part. So it has some advantages,long 
            life,trouble-free for a long time,and so on.
            ix.The valve block of hydraulic system are selected from north-Taiwan Seiki products.
            This valve block has some advantages,over-charge is big,a small resistance and pressure,hot loss is small,so the function is reliable.
