The low utilization efficiency of the plate when the existing shearing machine is in use is not taken into account; 2. In the patent document CN115870540B, the main method is to load and unload the plates and materials by setting a circular motion component, thereby improving the working efficiency and reducing the labor intensity. However, it does not take into account that the existing shearing machine cannot eliminate the initial deformation and unevenness of the plates when in use; 3. In the patent document CN104117722B, the main consideration is how to improve the precision and efficiency of shearing, but it does not take into account that the existing shearing machine is not convenient for directly performing automatic flatness detection on the sheared plate, and has poor flexibility; 4. In the patent document CN116174791B, the main consideration is how to reduce the damage degree of the blade and improve the safety of use, but it does not take into account the problem of low shearing efficiency of the existing shearing machine when in use.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Furthermore, before using the shearing machine, the distance between the laser distance sensor 3 and the top plane of the feed port of the shearing machine body 1 is recorded as A, the distance between the laser distance sensor 26 and the outer surface of one side of the opposite placement block 5 is recorded as A+, and the length of the plate is B. Then, the plate is transported to the shearing machine body 1 through the feeding table 35.

The automatic centering and correction shearing machine for plates according to claim 3 is characterized in that: The moving assembly 1 comprises a variable frequency motor 1 (18) mounted on the back of the storage box 2 (17); a reciprocating screw 1 (19) is mounted on the output end of the variable frequency motor 1 (18); one end of the reciprocating screw 1 (19) is connected to the front wall of the storage box 2 (17) through a shaft; a slide groove 1 is provided through the top of the storage box 2 (17); a sliding sleeve 1 (20) is sleeved on the outer surface of the reciprocating screw 1 (19); the top of the sliding sleeve 1 (20) passes through the interior of the slide groove 1 and is connected to the bottom of the storage block (21).

8. The automatic centering and correction shearing machine for plates according to claim 4 is characterized in that: The second moving assembly comprises a second protective tube (27) mounted on the front of the first storage box (25); a second variable frequency motor (28) is mounted on the front wall of the second protective tube (27); a second reciprocating screw (29) is mounted on the output end of the second variable frequency motor (28); one end of the second reciprocating screw (29) is connected to the rear wall of the first storage box (25) through a shaft; a second slide groove is provided through the bottom of the first storage box (25); a second sliding sleeve (30) is sleeved on the outer surface of the second reciprocating screw (29); the bottom of the second sliding sleeve (30) passes through the interior of the second slide groove and is connected to the top of the second storage box (31).

9. A method for using a plate automatic centering and correction shearing machine, applicable to the plate automatic centering and correction shearing machine according to any one of claims 1 to 6, characterized in that: How to use the shearing machine: S1. Before using the plate shearing machine, the plate is first conveyed to the plate shearing machine body (1) through the feeding table (35), and then the position and flatness of the plate are determined by the cooperation of the laser distance sensor 1 (3) and the laser distance sensor 2 (6), and the position and flatness of the plate are adjusted by the centering mechanism and the correction mechanism; S2, then start the cylinders (24) arranged in front and back to drive the pressing block (26) and the electric suction cup (32) to fit the plate, and then the plate can be limited; S3, then starting the hydraulic cylinder (33) to drive the cutter head (34) downward to perform a shearing operation on the fixed plate. After the shearing is completed, the plate is moved out of the shearing machine body (1) by moving component 2 so that it can be placed on the storage table (16); S4. In the process of pushing the plate out of the shearing machine body (1), the storage block (21) is moved by the moving component 1, and then the flatness and deformation of the sheared plate can be detected by the laser distance sensor 3 (22), so as to facilitate the corresponding processing operation of the plate according to the use requirements.

10. The method for using the automatic centering and correction shearing machine for plates according to claim 9 is characterized in that: In S1, it also includes: S11, when it is detected that the plate is tilted, the electric push rod (7) is started to drive the two sets of push plates (8) to approach each other, and then the plate can be pushed to be placed in the center under the action of the push plates (8); S21. When it is detected that the plate is uneven, the servo motor 1 (12) and the servo motor 2 are started to drive the upper pressure roller (13) and the lower pressure roller (15) to rotate respectively, and the hydraulic push rod (10) in the storage box 1 (9) is started to drive the upper pressure roller (13) to move downward, so as to adjust the leveling accuracy. Then, the initial deformation and unevenness of the plate can be eliminated by leveling before cutting the plate.
