Flattener eliminating residual stress inside composite board

Abstract

The invention discloses a flattener eliminating residual stress inside a composite board, and belongs to the field of composite board flattening machines. The flattener comprises a front flattener body, a rear flattener body, a connection rail between the front flattener body and the rear flattener body, a power transmission system driving the front flattener body and the rear flattener body to operate, and a pressing device adjusting reduction. The flattener is characterized in that working rollers of the front flattener body are arranged in the mode that an upper flattening roller is distributed in the middle of roller shafts, lower flattening rollers on the left and on the right are respectively distributed on the left side and on the right side of the roller shafts, working rollers of the rear flattener body are arranged in the mode that upper flattening rollers on the left and on the right are respectively distributed on the left side and on the right side of the roller shafts, a lower flattening roller is distributed in the middle of the roller shafts, all the flattening rollers can be adjusted horizontally on the roller shafts, and the roller surfaces are composed of a plurality of arches of different kinds of curvature, the arches are matched with the board shape of the composite board after being bent. The flattener has the advantage of being capable of eliminating the residual stress inside the composite board.

Description

technical field The invention belongs to the field of straightening machinery for composite boards, in particular to a straightening machine for eliminating residual stress in composite boards. Background technique At present, most of the composite panels used at home and abroad are made by welding, rolling, etc. However, no matter which method is used to produce the composite panels, they are composed of two different materials, and the expansion of the two materials Different coefficients will lead to residual stress inside the composite board. When the composite board is split, due to the release of the residual stress, the composite board will be longitudinally bent and deformed. This requires straightening before splitting to eliminate the internal stress of the composite board. At present, there is a lack of an effective mechanical device to eliminate the residual stress in the clad plate, which leads to bending deformation of the clad plate after rolling and splitting...

At present, most of the composite panels used at home and abroad are made by welding, rolling, etc. However, no matter which method is used to produce the composite panels, they are composed of two different materials, and the expansion of the two materials Different coefficients will lead to residual stress inside the composite board. When the composite board is split, due to the release of the residual stress, the composite board will be longitudinally bent and deformed. This requires straightening before splitting to eliminate the internal stress of the composite board. At present, there is a lack of an effective mechanical device to eliminate the residual stress in the clad plate, which leads to bending deformation of the clad plate after rolling and splitting.
