W12-20 x 2500 four-roller plate bending machine

Product Details

The machine features a four-roll structure, with the top roll as the main drive, which can also be driven simultaneously with the bottom roll. Power is supplied by a hydraulic motor to provide torque for rolling sheets. The bottom roll performs vertical lifting and lowering movements, achieved through hydraulic oil acting on the piston within the hydraulic cylinder, enabling sheet clamping for hydraulic transmission. On both sides of the bottom roll are side rolls, which move in an arc along the machine frame's guide rail, powered by hydraulic transmission. A notable feature of this machine is that pre-bending of sheet ends and rolling into a circle can be done on the same unit.
