A support seat 5 is arranged on the base 1, a first telescopic hydraulic cylinder 11 is arranged at the top of the support seat 5, a carrier plate 12 is fixedly installed at the output end of the first telescopic hydraulic cylinder 11, a grinding and leveling assembly is arranged at the bottom of the carrier plate 12, two fixing blocks 6 are arranged on the grinding and leveling assembly, and the grinding and leveling assembly is used for leveling and grinding an iron plate. A spring 7 is fixed at the bottom of the fixing block 6, a carrier block 8 is fixed at the bottom end of the spring 7, a baffle 9 is fixed on the two carrier blocks 8, and the two carrier blocks 8 and the two fixing blocks 6 are both located inside the baffle 9. The baffle 9 is of a square tubular structure. A limiting rod 10 is fixed on the upper surface of the carrier block 8, the spring 7 is sleeved outside the limiting rod 10, and a through hole for the limiting rod 10 to slide is formed in the fixing block 6.

[0023] The iron plate is adsorbed by the electromagnet 4, so that the iron plate can be kept stable during processing, thus facilitating the processing of the iron plate. The first telescopic hydraulic cylinder 11 is used to push the grinding and leveling assembly downward, so that the grinding and leveling assembly drives the two fixing blocks 6 to move downward. The fixing block 6 pushes the carrier block 8 downward by means of the spring 7, thereby driving the baffle 9 to move downward and abut against the support plate 3. The baffle 9 can completely wrap the periphery of the iron plate to be processed. As the first telescopic hydraulic cylinder 11 continuously moves downward, the grinding and leveling assembly contacts the iron plate and processes it. The debris generated during this process can be completely blocked inside the baffle 9, making the application of the baffle 9 more convenient and the chip blocking effect better. The use of the two springs 7 enables the grinding and leveling assembly to still move and be used normally inside the baffle 9 when the baffle 9 abuts against the support plate 3 and remains stationary.

[0024] Among them, the grinding and leveling assembly includes a rectangular frame plate 13, which is fixedly installed at the bottom of the carrier plate 12. Both fixing blocks 6 are fixedly installed on the rectangular frame plate 13, and the two fixing blocks 6 are symmetrically arranged with respect to the rectangular frame plate 13. A threaded lead screw 14 is rotatably connected between the opposite inner walls of the rectangular frame plate 13 through bearings. A slider 15 is threadedly connected to the threaded lead screw 14, and the slider 15 is slidably engaged with the inner wall of the rectangular frame plate 13. A first bevel gear 16 is fixedly sleeved on the outer part of the threaded lead screw 14. A first motor 17 is fixedly installed on one side of the rectangular frame plate 13. A transmission rod 18 is fixed to the output shaft end of the first motor 17, and a second bevel gear 19 is fixed to the other end of the transmission rod 18. The second bevel gear 19 meshes with the first bevel gear 16. A fixing plate 20 is fixed to the bottom of the slider 15. A first U-shaped seat 21 and a second telescopic hydraulic cylinder 22 are arranged on the fixing plate 20. A grinding roller 23 is rotatably connected between the opposite inner walls of the first U-shaped seat 21 through bearings. A second motor 24 is fixedly installed on one side of the first U-shaped seat 21. The grinding roller 23 is driven by the second motor 24. The output end of the second telescopic hydraulic cylinder 22 is fixedly installed with a second U-shaped seat 25. A flattening roller 26 is rotatably connected between the opposite inner walls of the second U-shaped seat 25 through bearings.

[0025] The first motor 17 is used to drive the second bevel gear 19 to rotate. By virtue of the meshing of the second bevel gear 19 and the first bevel gear 16, the threaded lead screw 14 can be driven to rotate, so that the threaded lead screw 14 can traction the grinding roller 23 and the flattening roller 26 to move in a screw drive manner. The second motor 24 drives the grinding roller 23 to rotate, so that the grinding roller 23 can grind the iron plate. The second telescopic hydraulic cylinder 22 can adjust the height of the flattening roller 26, so that when the flattening roller 26 is tractioned by the threaded lead screw 14 to move, the iron plate can be leveled first, and then the grinding roller 23 is used for grinding, avoiding poor grinding effect of the bent iron plate.

[0026] The working principle of this utility model:

[0027] During use, first place the iron plate to be processed on the support plate 3, energize the electromagnet 4, so that the electromagnet 4 can attract the iron plate to ensure that the iron plate cannot shake during subsequent processing. Control the first telescopic hydraulic cylinder 11 to push the rectangular frame plate 13 downward. The rectangular frame plate 13, with the help of the two fixing blocks 6 and the two springs 7, pushes the carrier block 8 and the baffle 9 downward, so that the baffle 9 abuts against the support plate 3 and wraps the iron plate to be processed. As the first telescopic hydraulic cylinder 11 continuously extends, the rectangular frame plate 13 moves downward relative to the baffle 9, and at this time the spring 7 is compressed;

[0028] The second telescopic hydraulic cylinder 22 is controlled to extend, so that the second telescopic hydraulic cylinder 22 pushes the flattening roller 26 downward, forcing the flattening roller 26 to be lower than the grinding roller 23. When the flattening roller 26 moves down to the specified height, the first motor 17 can be controlled to drive the second bevel gear 19 to rotate clockwise. By means of the meshing of the second bevel gear 19 and the first bevel gear 16, the threaded lead screw 14 can be driven to rotate, so that the threaded lead screw 14 pulls the flattening roller 26 to move, flattening the bent iron plate. After the flattening roller 26 is separated from the iron plate, the second telescopic hydraulic cylinder 22 is controlled to contract, so that the flattening roller 26 is higher than the grinding roller 23. The first telescopic hydraulic cylinder 11 is controlled to continue to extend, so that the first telescopic hydraulic cylinder 11 pushes the grinding roller 23 against the iron plate. The first motor 17 is controlled to stop running first, and then the second bevel gear 19 is driven to rotate counterclockwise, so that the threaded lead screw 14 pulls the grinding roller 23 to move along the iron plate. The second motor 24 drives the grinding roller 23 to rotate, so that the grinding roller 23 completes the grinding of the iron plate.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
