Description

Technical Field

[0001] This utility model relates to the field of steel plate processing, specifically a rust removal device for steel plate surfaces. Background Technology

[0002] Steel plates are flat steel products made by casting molten steel and then rolling them. They can be classified into thin plates, medium plates, and thick plates according to their thickness, and into various types according to their material, such as carbon structural steel, alloy structural steel, and stainless steel. They have high strength, good plasticity and weldability, and can be made into various components through cutting, bending, stamping and other processing methods. They are widely used in many fields such as construction, machinery manufacturing, automobiles, ships, and pressure vessels, and are an indispensable basic material in industrial production.

[0003] The processing of steel plates usually begins with heating the steel billet, rolling it multiple times to the target thickness, and then cutting and leveling it after cooling to ensure dimensional accuracy. Subsequently, it can be stamped, welded and assembled according to requirements, or its performance can be enhanced through surface treatments such as rust removal and painting, ultimately becoming an industrial component suitable for different scenarios.

[0004] After the steel plate is processed, it will be stored in a designated location. Long-term storage will cause the steel plate surface to oxidize. Most existing rust removal devices remove rust from one side and then flip it over to remove rust from the other side, resulting in low rust removal efficiency. Therefore, a steel plate surface rust removal device is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] Specific implementation examples are given below.

[0019] like Figures 1 to 5As shown in the embodiment of this utility model, a steel plate surface rust removal device includes a workbench 1; a pair of support rods 11 are fixedly connected to the top of the workbench 1; a support plate 12 is fixedly connected to the top of the support rods 11; a support frame 13 is fixedly connected to the top of the workbench 1; an electric push rod 14 is fixedly connected to the bottom of the support frame 13; a first fixed seat 15 is fixedly connected to the output end of the electric push rod 14; a motor 16 is fixedly connected to the side wall of the first fixed seat 15; a grinding shaft 17 is rotatably connected to the output end of the motor 16; and the electric push rod 14 is fixedly connected to the top of the workbench 1. During operation, the steel plate to be rusted is placed on top of the support plate 12, and then the pair of motors 16 are started to drive the grinding shaft 17 to rotate. The grinding shaft 17 below the support frame 13 and the grinding shaft 17 at the top of the workbench 1 rotate in opposite directions. Then, push the steel plate close to the grinding shaft 17, and push the electric push rod 14 on the support frame 13 to drive the grinding shaft 17 down. The two sides of the steel plate can contact the grinding shaft 17. Continue to push the steel plate, and the grinding shaft 17 can grind the rust on the surface of the steel plate. This means that the steel plate only needs to be pushed once in the middle of the support frame 13 to grind the rust on both sides at the same time. By rotating the grinding shaft 17 below the support frame 13 and the grinding shaft 17 on the top of the worktable 1 in opposite directions at the same time, the steel plate can be pushed once at the top of the support plate 12 to grind the rust on both sides at the same time. This reduces the need to flip the steel plate after grinding one side to process the other side, reducing grinding time. Push the electric push rod 14 on the support frame 13 to drive the grinding shaft 17 down to adjust the height. This can be adapted to steel plates of different thicknesses, reducing the decrease in grinding quality caused by different steel plate thicknesses.

[0020] like Figure 1 and Figure 3 As shown, a pair of fixed rods 2 are fixedly connected to the top of the workbench 1; the fixed rods 2 are located on one side of the support frame 13; a second fixed seat 21 is fixedly connected to the top of the fixed rods 2; a rotating shaft 22 is rotatably connected to the top of the second fixed seat 21; during operation, after the steel plate is ground from the middle of the grinding shaft 17, the bottom of the steel plate can contact the rotating shaft 22, and the rotating shaft 22 supports the ground steel plate, so that the steel plate will not sag due to gravity. When the steel plate is pushed to the top of the rotating shaft 22, the rotating shaft 22 can also rotate; by the rotating shaft 22 supporting the bottom of the steel plate, the steel plate can be kept in a horizontal state, reducing the overall bending of the steel plate caused by gravity, increasing the quality of the steel plate after rust removal, and the rotation of the rotating shaft 22 can also reduce the direct friction between the steel plate and the rotating shaft 22, which would cause wear on the bottom of the steel plate.

[0021] like Figures 4 to 5As shown, a dust pump 3 is fixedly connected to the side wall of the support frame 13; a dust suction pipe 31 is fixedly connected to the top of the dust pump 3; a pair of dust suction ports 33 are fixedly connected to the side wall of the support frame 13; the dust suction ports 33 are located between a pair of grinding shafts 17; a flow divider 32 is fixedly connected to the side wall of the dust suction port 33; the dust suction pipe 31 is connected to the flow divider 32; during operation, when the steel plate is being ground in the middle of the grinding shaft 17, the dust pump 3 can be started, and then the dust suction ports 33 can absorb the grinding residue on both the upper and lower surfaces of the steel plate. The flow divider 32 can disperse the airflow sucked in by the dust pump 3, so only one set of dust pump 3 is needed to absorb the residue on both the upper and lower surfaces of the steel plate; by setting the dust suction ports 33 between a pair of grinding shafts 17, the residue on both the upper and lower surfaces of the steel plate can be absorbed simultaneously, increasing the cleanliness of the steel plate surface after grinding and reducing the need for further processing after rust removal.

[0022] like Figures 1 to 2 As shown, the top of the support plate 12 has multiple sets of grooves 4; a rubber shaft 41 is rotatably connected to the middle of the groove 4; the rubber shafts 41 are arranged in an array at the top of the support plate 12; during operation, when the steel plate is pushed on the top of the support plate 12, the rubber shafts 41 can rotate in the middle of the groove 4, making it easier to push the steel plate on the top of the support plate 12; by rotating the arrayed rubber shafts 41 in contact with the steel plate, the sliding friction between the steel plate and the top surface of the support plate 12 is reduced, which can increase the convenience of rust removal of the steel plate and reduce the direct friction of contaminants between the steel plate and the top of the support plate 12, thus preventing scratches on the bottom of the steel plate.

[0023] like Figure 1 and Figure 3 As shown, a third fixed seat 5 is fixedly connected to the top of the workbench 1; a flexible pad 51 is fixedly connected to the top of the third fixed seat 5; the third fixed seat 5 is located on one side of the fixed rod 2; during operation, the polished steel plate can continue to move from the top of the fixed rod 2 and then contact the flexible pad 51. The tilt angle of the third fixed seat 5 can guide the steel plate to the top of the workbench 1; the tilt angle of the third fixed seat 5 can form a guiding force on the steel plate, which can guide the steel plate to move to the collection area at the top of the workbench 1 by gravity. The flexible pad 51 can also further protect the quality of the bottom of the steel plate.

[0024] like Figure 1 and Figure 4 As shown, a baffle 6 is fixedly connected to the side wall of the first fixed seat 15; the baffle 6 is inclined; during operation, when the grinding shaft 17 grinds and removes rust from the steel plate, the rotational force of the grinding shaft 17 will cause rust to fly. At this time, the baffle 6 can block the iron filings that fly from the grinding shaft 17; by the baffle 6 being inclinedly set on the side wall of the first fixed seat 15, it can block the iron filings that fly from the grinding shaft 17, reduce the spread range of iron filings, and facilitate subsequent centralized cleaning.

[0025] Working principle: The steel plate to be derusted is placed on top of the support plate 12. Then, a pair of motors 16 are started to drive the grinding shaft 17 to rotate. The grinding shaft 17 below the support frame 13 and the grinding shaft 17 on the top of the worktable 1 rotate in opposite directions. The steel plate is then pushed close to the grinding shaft 17, and the electric push rod 14 on the support frame 13 is pushed to drive the grinding shaft 17 to descend. Both sides of the steel plate can contact the grinding shaft 17. The steel plate is continued to be pushed, and the grinding shaft 17 can grind the rust on the surface of the steel plate. This allows the steel plate to be pushed once in the middle of the support frame 13 to grind the rust on both sides at the same time. After the steel plate is ground from the middle of the grinding shaft 17, the bottom of the steel plate can contact the rotating shaft 22. The rotating shaft 22 supports the ground steel plate, preventing it from sagging due to gravity. The steel plate is pushed to the top of the rotating shaft 22. When the steel plate is being ground on the middle of the grinding shaft 17, the dust pump 3 can be started. Then the dust suction port 33 can absorb the grinding residue on the upper and lower surfaces of the steel plate. The flow divider 32 can disperse the airflow sucked in by the dust pump 3. Only one set of dust pump 3 is needed to absorb the residue on the upper and lower surfaces of the steel plate. When the steel plate is pushed on the top of the support plate 12, the rubber shaft 41 can rotate in the middle of the groove 4, making it easier to push the steel plate on the top of the support plate 12. After grinding, the steel plate can continue to move from the top of the fixed rod 2 and then contact the flexible pad 51. The tilt angle of the third fixed seat 5 can guide the steel plate to the top of the worktable 1. When the grinding shaft 17 is grinding and removing rust from the steel plate, the rotation force of the grinding shaft 17 will cause rust to fly. At this time, the baffle 6 can block the iron filings that fly from the grinding shaft 17.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
