Description

Technical Field

[0001] The present application relates to the technical field of light alloy rolling, and in particular to a plate adjustment device used in light alloy rolling. Background Art

[0002] Rolling is a metal processing technology that uses the gap between one or more pairs of rollers to compress the metal material to reduce its cross-section while increasing its length. This process is mainly used to reduce the thickness of metals, including steel, magnesium, aluminum, copper and their alloys.

[0003] In the prior art, the methods for correcting the flatness and convexity of the plate include stretch straightening and roller leveling; among them, roller leveling mostly uses a single set of leveling rollers to level the plate, which will cause the plate to be excessively deformed due to the inconvenience of applying tension during the rolling process of light alloys, seriously affecting the production cost and production efficiency of the rolled plate, and the problem of being unable to guarantee the quality of the rolled products.

[0004] Combining the plate leveling technology after plate rolling with a single set of leveling rollers, here we provide a three-set leveling roller leveling device for rolling light alloy plates. Utility Model Content

[0006] The technical scheme of the utility model is as follows: a plate leveling device for light alloy rolling, comprising an upper leveling roller one (1), an upper leveling roller two (2) and an upper leveling roller three (3) located at the upper part, and a lower leveling roller four (4), a lower leveling roller five (5) and a lower leveling roller six (6) located at the lower part, wherein the upper leveling roller one (1) and the lower leveling roller four (4) form a group, the upper leveling roller two (2) and the lower leveling roller five (5) form a group, and the upper leveling roller three (3) and the lower leveling roller six (6) form a group, and the three groups of leveling rollers are arranged in sequence, evenly and closely along the rolling direction of the rolled plate (9).

[0007] Furthermore, each adjustment of the roller spacing of the three groups of smoothing rollers is the same as the adjustment of the spacing between the upper roller (7) and the lower roller (8), the rotation direction and rotation speed of the upper smoothing rollers one (1), two (2), and three (3) are the same as the rotation direction and rotation speed of the upper roller (7), and the rotation direction and rotation speed of the lower smoothing rollers four (4), five (5), and six (6) are the same as the rotation direction and rotation speed of the lower roller (8).

[0008] The purpose of the utility model is: by adopting the above technical scheme, the plate obtained by the flattening device after the light alloy is rolled is flatter, the excessive warping deformation occurring during the rolling process of the plate is effectively controlled, and the quality of the rolled plate shape is improved; at the same time, the operation is convenient and space is saved.
