At present many roller machine problems in rolling process, often encounter the rolling tube appear two small middle, usually we call this phenomenon as barrel distortion. The generation of deformation brings great inconvenience to welding or internal assembly. If the deformation is too large, it is necessary to reshaping the workpiece to meet the requirements of the latter process. The barrel deformation is mainly due to the thicker roll on the roller, the better rigidity, the lower roll, and the rigidity of the roll. The invention proposes that the upper roller, the left roll and the right roll adopt a round roll, and the lower roller adopts an elliptical roll. One end of the lower roller is connected by a coupling with a indexing device, which can rotate the lower roll and the plate according to the hardness of the plate material. When the hardness of the plate is high, the reaction force on the lower roll is larger, so that the long axis busbar with elliptical section can be contacted with the plate under the rotation of the lower roller to reduce the deflection of the lower roll. The indexing turntable is divided into six workstations. When the hardness of the coil material is low, the elliptical short axis busbar can be contacted with the plate, thus expanding the technological range of the four roll bending machine.
