[0002] With the rapid development of the manufacturing industry, the requirements for the quality and efficiency of metal surface processing are getting higher and higher. The Chinese patent application with the application number 202411388114.8 discloses "a surface grinding device for metal sheet processing, including a processing base plate and a first bracket installed at the bottom of the processing base plate for supporting it. The outer surface of the processing base plate is provided with a device main body, and the device main body includes: a conveying device, which is fixedly connected to the left side of the processing base plate. The conveying device is used for transporting metal sheets and can also cooperate with subsequent components to perform secondary grinding processing on the metal sheets to improve the grinding processing quality of the device. A first processing device, which is fixedly connected to the rear end surface of the processing base plate. The first processing device is used for spraying water on the processing surface of the metal sheet. The water fully contacts the oil stains, metal chips, and rust on the surface of the metal sheet, making the subsequent pretreatment of the metal sheet easier. This device has the advantages of improving the grinding processing quality of the device, avoiding secondary damage to the metal sheet, and being convenient for users to use";

[0015] The present invention also provides another technical solution: a processing method for the surface of a metal, including the following steps:

[0016] S1. Start the second motor, drive the transmission rod to rotate through the second motor, drive the material transporting rack to move through the second gear, so that the two translation seats move away from the rotating plate at the same time, drive the two material transporting platforms to move towards both ends of the box body through the two translation seats, place the metal plate to be processed on the plate conveyor belt on the material transporting platform. While driving the metal plate to move through the second motor, drive the plate conveyor belt to rotate to adjust the position of the metal plate, so that the end of the metal plate is close to one end of the material transporting platform close to the rotating plate;

[0017] S2. After the metal plate is placed, start the first motor, drive the rotating rod to rotate through the first motor. At this time, drive the grinding assembly to rotate through the connecting cylinder, so that the grinding assembly passes through the rotating window from outside the box body and enters the box body, drive both grinding assemblies to rotate to be perpendicular to the inner wall of the box body, and drive the grinding assembly to work to grind the metal surface;

[0018] S3. When the material transporting platform moves to the end of the rotating plate, continue to drive the metal plate to move through the plate conveyor belt provided on the material transporting platform. When the metal plate moves, grind the surface of the metal plate through the grinding assembly. The part with the surface ground is gradually fed between the two groups of clamping cylinders, and the metal plate moves to another material transporting platform. Continue to drive the metal plate to move through the plate conveyor belt provided in the other material transporting platform until the end of the metal plate is ground;

[0019] S4. After the end of the metal plate is ground, drive the metal plate to continue to move, so that the end of the metal plate moves between a group of clamping cylinders close to the plate inlet end. Then, pull the connecting plate towards the direction of the third motor through the electric push rod, drive the clamping rack to move through the connecting plate. When the clamping rack moves, drive the threaded rod to rotate through the third gear. When the threaded rod rotates, drive the two sliders on the threaded rod to move towards both ends of the threaded rod at the same time. At this time, drive the clamping plate to move downwards through the connecting arm, so that the two clamping plates between the two groups of clamping cylinders move towards the plate at the same time, and clamp the metal plate through the clamping plate. Adjust the displacement of the electric push rod pulling the connecting plate according to the actual thickness of the metal plate, so that the device is applicable to metal plates of different thicknesses;

[0020] S5. After the metal plate is clamped, start the third motor, drive the rotating plate to rotate through the third motor, so that the clamping cylinder rotates with the rotating plate at the same time, and drive the metal plate to rotate at the same time and rotate half a circle to complete turning over;

[0021] S6. While the metal sheet is rotating, drive the rotating rod to reverse by the first motor, so that the grinding assembly moves out of the box through the rotating window after passing through the box body. And during this process, drive the grinding assembly to rotate through the meshing of the first gear and the toothed plate, so that the grinding assembly rotates while rotating around the rotating rod, and the bottom end of the grinding assembly rotates 90 degrees through its own rotation, so that the bottom end leaves above the material transportation platform, facilitating its passing through the rotating window. After the metal sheet is turned over, adjust the position of the end of the metal sheet through the material transportation platform and the sheet conveyor belt arranged therein, and then grind it through the grinding assembly. After both sides are ground, transport the metal sheet out of the box through the material transportation platform.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The present invention is designed and installed with a grinding mechanism, a material transportation mechanism and a clamping and turning mechanism. The metal sheet is ground by the grinding assembly. After one side is ground, clamp one end of the metal sheet by the clamping plate and drive the rotating plate to rotate to turn over the metal sheet. After turning over, adjust the position of the end of the metal sheet through the material transportation platform, and then grind it through the grinding assembly, realizing the effect of double-sided grinding of the metal sheet. And while the metal sheet is being turned over, drive the grinding assembly to rotate around the rotating rod, so that the grinding assembly does not block the metal sheet from falling on the material transportation platform when the metal sheet is turned over. By adjusting the displacement of the clamping rack, the clamping plate can clamp metal sheets of different thicknesses, so that the device can be applicable to metal sheets of different thicknesses, improving the applicability of the device. By automatically turning over the metal sheet after one side is ground, the surface processing efficiency of the metal sheet is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] S4. After the end of the metal sheet is ground, drive the metal sheet to continue to move, so that the end of the metal sheet moves between a group of clamping cylinders 403 close to the sheet inlet end.

[0048] S6. While the metal sheet is rotating, drive the rotating rod 203 to reverse through the first motor 208, so that the grinding assembly 205 moves out of the box body 1 through the rotating window 201 after passing through the box body 1. And during this process, through the meshing of the first gear 206 and the toothed plate 207, drive the grinding assembly 205 to rotate, so that the grinding assembly 205 rotates while rotating around the rotating rod 203. Through the self-rotation of the grinding assembly 205, the bottom end thereof rotates 90 degrees, so that the bottom end thereof leaves above the material transporting platform 303, facilitating its passing through the rotating window 201. After the turning over of the metal sheet is completed, adjust the position of the end of the metal sheet through the material transporting platform 303 and the sheet conveyor belt arranged therein, and then grind it through the grinding assembly 205. After both sides are ground, transport the metal sheet out of the box body 1 through the material transporting platform 303.
