Abstract

An adjustable roll-bending precision leveling machine relates to a leveling machine, which solves the problem that a common leveling machine cannot level a large or curved plate in the transverse direction. It includes a machine base, a leveling unit installed on the machine base and composed of several leveling rollers, the leveling unit includes work rolls, intermediate rolls and support rolls, and the feature is that the support rolls are fixed in the support roll seat , the bottom surface of the support roller seat is an arc surface and fits the middle inclined block with an arc surface groove on the upper part, there is a groove under the middle inclined block, and a bottom inclined block is arranged in the groove; The shaft sleeve moving along the axial direction is fixed, the two ends of the work roll are fixed on the movable support, and the movable support is fixed on the fixed support through the screw rod and disc spring. The contact surface between the movable support and the fixed support is arc-shaped. In the present invention, by adding a support roller seat with an arc-shaped bottom under the support roller, the camber of the leveling roller can be adjusted at the curved plate to increase the deformation of the plate here, and the internal stress can be eliminated to achieve the effect of leveling the plate. .

Description

technical field [0001] The invention relates to a leveling machine, in particular to an adjustable roll-bending precision leveling machine. Background technique [0002] The leveling accuracy of the leveling machine is closely related to the stiffness of the beam and the flatness of the leveling roller system. Usually the roll system of the leveling machine is not adjustable, so the leveling machine can only level the longitudinal bending and slight transverse bending deformation of the sheet, and the cold-rolled plate, stainless steel plate and aluminum alloy plate with poor rolling quality are prone to transverse deformation. For the problem of large or curved plates, the current leveling machine cannot solve the leveling of large or curved plates in the transverse direction. invention content [0003] The object of the present invention is to provide an adjustable roll-bending precision leveling machine to solve the problem that ordinary leveling machines cannot level ...
