Structure type four- roll machine , on the main drive roller through the gear reducer output gear meshing with the roller , to provide torque for the roll sheet ; under the roller moves vertically through the hydraulic cylinder of the hydraulic oil acts on Pistons acquired in order to clamp plate for hydraulic transmission ; the next roll of the sides with side guide rollers and for tilting movement along the rack , through the screw thread female worm drive ; machine advantage of pre- end plate Bending and rolling can be conducted on the same machine .
