Description

[0032] In one embodiment, for the spray box 27, a material storage fixed frame 35 for spraying steel billets is arranged above the spray box 27, a first stirring rod 30 for stirring is arranged inside the material storage fixed frame 35, the first stirring rod 30 is connected to the fourth transmission belt 33 for transmission, and a spray gun 34 for spraying steel billets is arranged below the material storage fixed frame 35.

[0033] In this embodiment, as the main place for steel billet spraying, various spraying-related components are arranged inside, such as filter plate 24, steel billet lower spraying plate 29, etc. It can provide a spraying environment that can be filtered for the steel billet, which is convenient for the recovery of spraying materials.

[0034] In one embodiment, for the above-mentioned support bracket 1, the side is rotatably connected to the second bevel gear 22, the support bracket 1 is rotatably connected to the first bevel gear 21, and the side of the support bracket 1 is provided with a drying plate 32 for drying the steel billet.

[0035] In this embodiment, it serves as the supporting structure of the entire rolling device and provides an installation foundation and a stable working platform for other components.

[0036] In one embodiment, for the above-mentioned symmetrical threaded rod 9, threads in opposite directions are arranged on the surface of the symmetrical threaded rod 9.

[0037] In this embodiment, the surface is provided with threads in opposite directions, which are used to drive the first clamping block 7 and the second clamping block 8 to move relative to or away from each other. The rotation of the clamping blocks can accurately control the position of the clamping blocks, realize the clamping and loosening of the steel billet, and can provide a larger clamping force through the thread transmission.

[0038] In one embodiment, for the spray box 27, the spray box 27 is rotatably connected to a rotating roller 28, a filter layer for filtering billet residue is arranged inside the filter plate 24, a protective plate 18 is fixedly connected above the stabilizing block 19, the side of the protective plate 18 is fixedly connected to the supporting bracket 1, and a cleaning layer for cleaning the filter plate 24 is arranged above the friction block 26.

[0039] In this embodiment, the stirring inside the spray box 27 facilitates uniform spraying, thereby increasing the protection against corrosion of the steel billet.

[0040] The working principle of a high-strength low-alloy steel atmospheric corrosion resistance rolling device in the present invention is to place the steel billet to be rolled above the square fixed frame 3, and then the first push rod 4 will rub against the steel billet to drive it to roll above the second push rod 5, and then by controlling the rotation of the symmetrical threaded rod 9, the first clamping block 7 and the second clamping block 8 move toward each other along the sliding plate 10, and finally clamp the steel billet, and then the cleaning scanning block 16 will record the position of the upper surface of the steel billet, and then the rotating rod 11 will rotate, at this time the square fixed frame 3 drives the steel billet to rotate, and records the uneven positions on the back of the steel billet.

[0041] Then the square fixed frame 3 is controlled to rotate. At this time, the water gun nozzle 6 fixed under the nozzle support frame 15 will use high-pressure water gun to clean the surface of the steel billet. When encountering uneven positions, the cleaning scanning block 16 will clean its surface by adjusting the pressure of the water gun nozzle 6 to prevent changes in the stress structure of the steel billet material. Then the parts blocked by the sliding plate 10 can be blocked by the reverse rotation of the first clamping block 7 and the second clamping block 8, and then the first push rod 4 and the second push rod 5 roll to adjust the position to clean the blocked position. After cleaning both sides of the steel billet, the first push rod 4 and the second push rod 5 will roll to move the steel billet. When moving to the drying plate 32 position, the surface of the steel billet will be dried, and then the next step of silicate coating spraying will be prepared. When spraying the surface of the steel billet, there are an upper nozzle spray gun 34 and a lower nozzle steel billet lower spray plate 29.

[0042] When drying the surface of the steel billet, the rotation of the first stirring rod 30 will stir the inside of the drying plate 32 through the fourth transmission belt 33 to ensure the uniformity of the silicate material spraying, and then the upper and lower surfaces of the steel billet will be sprayed. When the next steel billet material is to be cleaned on the surface, the rotation of the rotating rod 11 will drive the cleaning threaded rod 13 to rotate through the first transmission belt 12. The rotation of the cleaning threaded rod 13 will drive the cleaning block 17 to move, and push the impurities falling from the steel billet until they move to the impurity treatment port 20 for discharge. When cleaning the surface of the steel billet material, the rotating rod 11 will rotate in one direction until the cleaning block 17 slides to the position where the impurities are cleaned and then starts to rotate in the opposite direction.

[0043] When the rotating rod 11 rotates, the cleaning threaded rod 13 is driven to rotate through the first transmission belt 12, and the rotation of the cleaning threaded rod 13 drives the first bevel gear 21 to rotate. The first bevel gear 21 will drive the anti-clogging threaded rod 25 to rotate through the second bevel gear 22 and the third transmission belt 23. When the anti-clogging threaded rod 25 rotates, it will follow the same rotation trajectory of the cleaning threaded rod 13, rotate to one side and then return. The rotation of the anti-clogging threaded rod 25 drives the friction block 26 to clean the filter plate 24, ensuring that the surface of the filter plate 24 will not cause some metal particles to remain due to the spraying of silicate material, thereby avoiding subsequent clogging when circulating to the upper and lower spray guns.

[0044] 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.
