Abstract

The invention discloses a straightening machine used in the field of aluminum plate production. The straightening machine comprises an upper machine frame and a lower machine frame. An upper roller system is arranged on the upper machine frame. A lower roller system is arranged on the lower machine frame. The upper roller surface of the lower roller system is a plane. The upper roller system is arranged in a V shape in the vertical direction. The upper roller system and the lower roller system are arranged in parallel. According to the straightening machine, the lower roller system is flat, the upper roller system is arranged in the V shape in the vertical direction, and thus, aluminum plates in a wider thickness range can be straightened. A straightening machine in the prior art can onlymachine aluminum plates in the thickness range of 0.3-1.5mm and in the thickness range of 1.5-4.5mm. The straightening machine provided by the invention can machine aluminum plates in the thickness range of 0.3-6mm. Enterprises do not need to introduce production lines for machining aluminum plates within different thickness ranges anymore, the production cost is reduced, and the problem that an existing straightening machine is narrow in straightening range and cannot be used for producing aluminum plates with different thickness requirements is solved.

Description

technical field [0001] The invention relates to the field of aluminum plate production, in particular to a straightening machine. Background technique [0002] Aluminum coils need to be straightened before being cut into rectangular flat plates. At present, in the production of cross-cutting equipment in steel shearing processing centers, the straightening unit generally adopts roller leveling machines. The roller straightening machine uses multiple straightening rollers to continuously produce bending deformation of the aluminum plate to eliminate the uneven curvature of the aluminum plate, so that the bending curvature gradually decreases from large to small, and finally a straight aluminum plate is obtained. The strip is bent repeatedly under the action of a pair of straightening rollers, the outside is stretched, the inside is squeezed, and finally achieves plastic deformation. This process achieves the purpose of eliminating residual internal stress inside the strip, e...
