Description

Technical Field

[0001] The invention relates to the technical field of plate leveling, and in particular to a high-efficiency leveling device and method for special-shaped metal plates. Background Art

[0002] During the leveling process of special-shaped metal sheets, the leveling roller assembly is mainly used to apply pressure to the sheet so that the stress inside the sheet can be redistributed and released. When the sheet enters the leveling roller assembly, the pressure between the upper and lower leveling rollers causes the sheet to undergo a certain plastic deformation, thereby achieving the purpose of leveling. However, during the leveling process of existing special-shaped metal sheets, repeated leveling is usually required before flatness testing can be performed, and the leveling efficiency is low.

[0003] The defects of the existing leveling device are: 1. In the patent document CN222058519U, the main consideration is how to adapt metal sheets of different widths for leveling, but it does not take into account the problem that the existing special-shaped metal sheets usually need to be leveled repeatedly before flatness detection during the leveling process, resulting in low leveling efficiency; 2. In the patent document CN219004156U, the processing efficiency is improved mainly by limiting the stainless steel sheet through a limiting mechanism, but it does not take into account that the existing special-shaped metal sheet cannot be tested for bending deformation during the leveling process, and the practicality is poor; 3. In the patent document CN207899902U, multi-cylinder and multi-pressure head are mainly used to improve the leveling efficiency of metal plates. It does not take into account that the existing special-shaped metal plates need to be leveled by Guoci before the plate is manually tested for flatness, which leads to low leveling efficiency of the plate; 4. In the patent document CN210847726U, the main consideration is how to improve the convenience of adjusting the gap size between the rollers, but it does not take into account that the existing special-shaped metal sheets still need to be manually picked up and placed during the leveling process, and the degree of automation is low.

[0013] Preferably, the leveling method of the special-shaped metal sheet is as follows: S1. First, place the metal sheet to be leveled on the storage table, then use the robotic arm to drive the suction cup close to the metal sheet, and use the suction cup to absorb and lift the metal sheet, and then send it into the main body of the leveling machine for leveling operation; S2. After the special-shaped metal sheet is leveled once, the sheet is sucked up by a suction cup and moved from one set of storage tables to another set of storage tables by a moving component. During the transportation process, the flatness of the bottom of the special-shaped metal sheet is detected by an intelligent sensor array. S3. According to the structure detected by the intelligent sensor array, it is determined whether it is necessary to feed the special-shaped metal sheet into the main body of the leveling machine for secondary leveling operation until the sheet is flat.

[0017] 3. In the process of transporting special-shaped metal plates from one group of storage tables to another group of storage tables, the present invention records the distance from the intelligent sensor array at different positions to the bottom surface of the plate to determine whether the values ​​are the same. If they are different, the bottom of the plate is still uneven and leveling operation needs to be continued. Otherwise, the bottom surface of the plate is flat and it needs to be placed on the storage table and the plate needs to be tested for flatness using a flatness detection component, which can improve the efficiency of plate leveling to a certain extent.
