(1)The structure of this machine has four rollers, the upper roller is main drive, through the hydraulic motor provides the power to provide torque for coiled sheet; lower roller for vertical movement by hydraulic cylinder, to the clamping was coiled sheet, and the realization of non symmetric bending roll system.

(2)This machine is three rollers symmetries rolling mild steel or mild alloy steel under normal temperature condition (such as Q235, Q345, 16MnR, etc.) into cylinders.

(3)The machine is suitable for sheet metal bending, can be rolled round and arc and within a certain range of conical workpiece, and sheet metal bending function, the remaining straight edge, high work efficiency, and can be used crude the metal plate to be leveling.

(4)The upper roller is arranged the side roller device, the side roller is parallel to the roller axis for arc lifting motion, the side roller arc movement by the hydraulic cylinder.
