This machine mainly composed by machine frame, top roll part, bottom roll part, nether support roll device, main transmission device, chassis, feeding and correcting device ,hydraulic system, electrical system and other components.
3-1 ,
3-1 machine frame
Machine frame is steel welded box-shaped structure, with good bending rigidity.
3-2 top roll device
Top roll part mainly composed of main cylinder, beam, bearing base, top roll, upper support roll and so on. 1100Tons ,
Two main cylinders provide pressure 1100Tons to bend plate. Cylinders’ working pressure is 19.5MPa. Box-shaped beam structure welded with steel plate, good bending stiffness. 5 groups upper support rolls arranged under the beam prevent top roll having a big deflection in the load condition. The installation of double-row roller bearing double row self-aligning bearings to reduce friction resistance, the position on the roller by the roller bearing mounted on the side of
