This machine has a structure of 3 roller symmetrical type, upper roller can go up and down in the symmetric position over the center of both lower rollers and the motion can be obtained through hydraulic oil acting on piston inside hydraulic cylinder called hydraulic drive. Both lower rollers can have a rotating motion, which can provide a torque for rolling plate materials through the meshing between output gear of reducer and gear of lower roller. Under the bottom of both lower rollers, there are several supporting rollers in order to improve the stiffness of lower roller and have a vertical adjustment. On the top of the upper roller there is a rigid crossbeam, there are several supporting rollers between the crossbeam and upper roller that they can improve the stiffness of upper roller, suitable for rolling of super-width, arc type components.Main characteristics:·Superior product’s accuracy·With unique bending technology, high accuracy of pre-bending terminal, continuous bending without back corner and digital control in the process of bending.·Man-machine dialogue control interface with a high-efficient and intelligent operation.·Physical bending process software, man-machine dialogue window, automatic compensation in the process of bending.
