4-Rollen-Biegemaschine, Biegemaschine, rol

4-roller bending machine,plate bending machine,rolling machine adopts the the four -roller structre with the upper roller as the main drive,providing the plates bendingwith torque through the engagement between the gear of the moderator and the gear of the upper roller.The lower roller makes vertical movements and imposes a force on the pisiton through the hydraulic oil in the hydraulic cylinder so as to clamp the plate tight.Side rollers are arranged on the two sides of thr lides of the lower roller,and make inclining movement along the guide rail,and provide drive through the screw,the nut,the worm and the lead screw.The advantage of the machine is that the preliminary bending and rolling of the top ends of the plates can be conducted on the same machine.
