Problems solved by technology

When adjusting the bending deformation of the plate, it must be adjusted by turning the large beam to drive the upper leveling work roll and the upper support roll to rotate as a whole at the same time, and the single leveling work roll cannot be adjusted independently
Therefore, after the metal sheet enters the leveling machine, the forward and reverse bending deformations of the upper and lower leveling work rolls to the sheet can only be sequentially and linearly changed, and the optimal unequal nonlinear change cannot be achieved. At the same time, due to the large shape and mass of the large beam, it is difficult to adjust the rotation

Abstract

The invention discloses a working roll adjusting device for a roll leveler. In the invention, each working roll is provided with a wedge I and a wedge II of which the inclined surfaces are matched up and down along the axial direction; a support roll assembly is arranged on the wedge I; a wedge adjusting device is arranged on the end part of the wedge II; the wedge adjusting device is used for driving the wedge II to move transversely; and the wedge II is used for pushing the wedge I upwards and downwards. The work roll adjusting device can be used for independently adjusting the vertical direction of each working roll, so that the leveling quality is improved.

Description

technical field [0001] The invention relates to a metal plate roller leveling machine, in particular to a work roll adjustment device of the roller leveler. Background technique [0002] Roller leveling machine for sheet metal is to carry out multiple forward and reverse bending on the sheet metal through multiple leveling work rolls of the upper leveling roller row and the lower leveling roller row that are actively rotating, and through the gradually changing bending deformation, Work hardening to level metal sheets. According to the leveling principle of the metal sheet, after the metal sheet enters the leveling machine, the bending deformation of the upper and lower leveling work rolls on the sheet should be gradually nonlinear in the direction of sheet metal leveling, according to the material of the metal sheet Different, the original curvature is different, and the leveling process parameters are also different. This change should be adjusted within a certain range. ...
