[0002] With the acceleration of the global industrialization process, the demand for metal sheets continues to grow. Metal sheets are widely used in many fields such as construction, automobiles, machinery manufacturing, and home appliances. In the construction field, metal sheets are used to build roofs, walls, and decorations; in the automotive industry, metal sheets are key materials for manufacturing car bodies and parts; machinery manufacturing and home appliance production are also inseparable from metal sheets of various specifications and performances. In order to meet the diverse needs of different fields for metal sheets, it is necessary to continuously improve processing technology and equipment. Among them, the ginning machine plays an important role in the surface treatment and functional improvement of metal sheets; There are still the following defects in specific use: 1. Plates from different sources have different quality characteristics, such as hardness, toughness, thickness uniformity, etc. This will bring great challenges to the setting of process parameters during the production process. At the same time, in large-scale production, product consistency is a very important quality indicator. The quality differences of plates from different sources will lead to inconsistencies in the appearance and performance of the final product. Secondly, the quality of plates from different sources is unstable, which increases the risk of product quality problems.

[0003] 2. Secondly, during the operation of the equipment, if it is subjected to abnormal loads caused by bending, the various parts of the equipment will be deformed or displaced. This will directly affect the processing accuracy or operation accuracy of the equipment. The equipment load caused by bending will increase the running resistance of the equipment, so that more energy will be consumed to maintain normal operation. This will lead to a decrease in the energy utilization rate of the equipment and a decrease in operating efficiency.

[0022] The complete working principle and steps of the above embodiment are as follows: Initial qualification: Figure 1 As shown, the metal sheet is first fed into the feeding area of ​​the rolling mill body 1 through a conveying device or other feeding system, and then the sheet is compressed and shaped by the working roller 11. The rolling mill body 1 is usually equipped with a working roller 11 and a supporting roller 14 and driven by a chain wheel 12 to rotate at different speeds to generate shearing and compression forces, so that the thickness of the sheet is reduced and the width and length are increased. Finally, in the continuous rolling process, the sheet is continuously rolled multiple times by the working roller 11 and the supporting roller 14 to achieve the desired thickness and shape, and the gap between the working roller 11 and the supporting roller 15 can be manually adjusted to control the thickness of the sheet; When using: End-centering clamping mechanism that ensures uniform flattening of the sheet metal by stabilizing the sheet metal position and thus avoiding deviation 2 steps: like Figures 3 to 5As shown, when the operator puts the metal sheet through the conveying device onto the surface of the sheet material bottom plate 24 and sends it to the working roller 11 for compression and shaping, the operator can first turn the handle 211. Since one end of the handle 211 is fixedly connected to the center of the synchronous belt 210, and the synchronous belt 210 is transmission-connected to the outer wall of one end of the threaded rod 27, the rotation of the handle 211 will drive the synchronous belt 210 to transmit, so the rotation of the synchronous belt 210 will drive the threaded rod 27 to rotate, and the moving block 28 and the threaded rod 27 form a ball screw structure, so that the threaded rod When the moving block 27 rotates, the moving block 28 will move to the left. In addition, two right obstacle columns 29 are symmetrically fixedly installed on the outer wall of the moving block 28, and two left obstacle columns 26 are fixedly installed on both sides of the opening long plate 25. Therefore, when the moving block 28 moves to the left until the two right obstacle columns 29 are in contact with the outer wall of the sheet material bottom plate 24, the two right obstacle columns 29 and the two left obstacle columns 26 are in contact with the sheet material bottom plate 24 through the movement of the moving block 28. In this way, the end of the metal sheet placed on the surface of the sheet material bottom plate 24 is clamped and fixed. In addition, when the moving block 28 moves to the left, the two right obstacle columns 29 and the two left obstacle columns 26 are in contact with the sheet material bottom plate 24. During the side movement, the central bottom end of the moving block 28 is rotatably connected to the rotating rod 213, and the end of the rotating rod 213 away from the moving block 28 is also rotatably connected to the connecting rod 214, and the end of the connecting rod 214 away from the rotating rod 213 is also rotatably connected to the bottom end of the opening long plate 25. Therefore, during the movement of the moving block 28, the rotating rod 213 and the connecting rod 214 shrink inward and deflect. At the same time, a line-fixing pen 215 is fixedly installed at the end of the rotating rod 213 close to the connecting rod 214, and the line-fixing pen 215 is in contact with the bottom end of the plate material bottom plate 24. Therefore, when the connecting rod 214 is moved, the rotating rod 213 and the connecting rod 214 are moved inward and deflected. After the rotating rod 213 is retracted inward, the operator can push the opening long plate 25 to move left and right at the bottom of the plate material bottom plate 24, thereby driving the line-fixing pen 215 to horizontally carve on the surface of the bottom end of the plate material bottom plate 24. If the markings on the bottom of the plate material bottom plate 24 are difficult to observe or the line of sight is limited, auxiliary tools such as flashlights, mirrors, telescopes, etc. can be used to better observe and judge. At the same time, if it is necessary to more accurately observe and measure the markings on the bottom of the plate material bottom plate 24, measuring tools such as calipers and measuring rulers can be used to measure and record; Used to add notches or textures to the surface of a sheet to increase surface roughness. 3 steps of scoring and texturing: like Figure 6 to Figure 7As shown, when the moving block 28 moves to the left, the external push tube 31 fixedly connected to the upper surface of the moving block 28 will push the slider 32 fixedly connected to one end of the external push tube 31 to move to the left inside the slide rail groove 33 as the moving block 28 moves. Then, when the slider 32 moves to the left inside the slide rail groove 33, the transfer rod 34 connected to the bottom end of the slider 32 will be pulled to deflect, and the deflection movement trajectory of the transfer rod 34 is sliding inside the V-shaped groove plate 35. The shape of the V-groove plate 35 is V-shaped, so when the transfer rod 34 performs a V-shaped deflection movement inside the V-groove plate 35, it will pull the crank 36 connected to one end of the transfer rod 34 to deflect and move. In this way, the deflection displacement trajectory of the crank 36 is a heart-shaped curve trajectory, and the connecting pen 37 fixedly connected to the surface of one end of the crank 36 will follow the heart-shaped curve movement trajectory of the crank 36 to carve the lower surface of the plate material bottom plate 24, so that the flatness of the plate can be indirectly judged; The resistance bending mechanism helps keep the plate straight during rolling and prevents the plate from bending or deforming during rolling. 4 steps: like Figures 8 to 9 As shown, when the connecting rod 214 contracts inward and deflects, the small bevel gear 41 that penetrates and rotates and is connected to one end of the connecting rod 214 will rotate synchronously, and then the large bevel gear 42 that meshes with the outer wall will rotate synchronously, thereby the rotation of the large bevel gear 42 will drive the short rod 43 that is connected to one side of the large bevel gear 42 to deflect upward, so the upward deflection of the short rod 43 will pull the long rod 44 that is connected to the outer wall of one side of the short rod 43 to deflect upward, and the upward deflection of the long rod 44 will pull the double-headed rod 45 that is connected to one end of the long rod 44 to deflect downward, so the downward deflection of the double-headed rod 45 will The buckle 46 connected to one end of the double-headed rod 45 is deflected upward, so that the arc surface of one side of the buckle 46 rubs against the outer wall of the friction wheel 48, thereby pushing the friction wheel 48 to rotate. In addition, when the double-headed rod 45 deflects downward, the caliper plate 47 connected to the axis of the outer wall of the double-headed rod 45 pushes the friction wheel 48 connected to one end of the caliper plate 47 to rotate slowly. As a result, the rotation of the friction wheel 48 causes the sandpaper covering the outer wall surface of the friction wheel 48 to rub against the outer wall of the bottom end of the sheet material bottom plate 24, thereby helping the metal sheet to resist bending and warping caused by pressure and temperature changes during rolling. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
