3-Roller Symmetry Bending Machine for Shipbuilding Features of 3-Roller Symmetry Bending Machine for Shipbuilding: - The upper roller of this plate bending machine makes vertical lifting movement at symmetry place of two bottom rollers center, through hydraulic oil in the hydraulic cylinder acting on piston pole, so it is hydraulic transmission - Two bottom rollers make rotary movement. Motor joins bottom roller through gear reducer and universal chain coupler, providing torque for rolling plate - Under the two bottom rollers, there are multiple sets of support rollers, which can improve the rigidity of the bottom rollers. - There is a rigid beam on the top of the upper roller. There are many sets of support rollers between the beam and upper roller, thus enhancing the rigidity of the upper roller. - This metal bending machine is applied for making wide arc type work piece. - NC control and CNC control are optional.
