Straightening method suitable for composite steel sheet

Abstract

The invention relates to the technical field of machinery, in particular to a straightening method suitable for a composite steel sheet. A bottom plate is included, and a conveying mechanism is fixed to the bottom plate; a fixing mechanism is installed on the conveying mechanism in a matched mode. A guide mechanism slides on the fixing mechanism; a straightening mechanism is mounted on the conveying mechanism; a lubricating mechanism is fixed on the conveying mechanism; after the steel plate is placed on the conveying mechanism, a control switch of the guide mechanism can be turned on, so that the guide mechanism slides in the fixing mechanism, and the steel plate can be conveniently guided when conveyed; a control switch of the conveying mechanism is turned on, so that the steel plate can be conveyed when the conveying mechanism rotates, and meanwhile, the steel plate can be conveniently conveyed into the straightening mechanism; and lubricating oil is injected into the lubricating mechanism, and when the conveying mechanism rotates, the lubricating oil in the lubricating mechanism can lubricate the conveying mechanism, so that the use effect of the conveying mechanism is improved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a method for straightening a composite steel plate sheet. Background technique [0002] Thin steel sheets are steel sheets with a thickness between 0.2 and 4 mm produced by hot rolling or cold rolling. The width of the thin steel plate is between 500 and 2500mm. They are mainly used in the automotive industry, electrical industry, machinery industry and other sectors. When the clad steel plate is manufactured, in order to ensure that the unevenness of the product meets the standards and customer requirements before leaving the factory, it is necessary to cold straighten the clad steel plate. [0003] However, due to the fact that the existing straightening machine has a certain range of straightening thickness, one straightening machine cannot be used for the straightening of all thicknesses of clad steel plates, and the deflection and edge-to-wave ratio of the clad steel pla...

Problems solved by technology

[0003] However, since the existing straightening machines have a certain range of straightening thicknesses, one straightening machine cannot be used for straightening composite steel plates of all thicknesses, and the deflection and edge wave ratio A single carbon steel plate is large and has strong elastic deformation force, so it is not easy to be leveled; in addition, when the steel plate is straightened, because the composite steel plate is relatively curved, the thin plate is displaced during straightening, which is easy to affect the composite steel plate. The straightening effect; and after the straightening machine conveying roller table runs for a long time, the rotation effect becomes worse, which is not conducive to improving the use efficiency of the device
