Along with the enhancement of the quality consciousness of products, the precision requirement on a rolled plate is higher and higher, the requirement on the rolling capacity of a plate rolling machine is higher and higher, the thickness of the rolled steel plate is larger and larger, the rolling diameter of some workpieces is smaller, under the condition, the stress of a working roll is large during plate rolling, especially the stress is larger during pre-bending of a plate head, but the diameter of the rolling circle is smaller, and the diameter of an upper working roll cannot be too large according to the calculation result of resilience after the plate is bent during design. In the rolling process, the roller can generate deflection deformation under the action of self gravity and working load, so that rolled workpieces cannot be well closed, the straightness and curvature cannot meet the technical requirements, the rolling quality of the workpieces is directly influenced, if the deformation is too large, the normal work of the roller can be influenced, and the deflection compensation needs to be carried out on the working roller to solve the problems. At present, the deflection compensation of the working roll on the domestic plate bending machine mainly has two forms: firstly, a cross beam is arranged between two gantry frames, and the lower end of the cross beam is provided with an upper roller and a supporting roller, and the compensation mode has the defect that a cylindrical workpiece cannot be rolled due to the limitation of process conditions; the other mode is that a longer upper roller is adopted, and two ends of an upper working roller are respectively applied with a pre-load of reverse deformation.
