                          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.
