Detailed implementation manner

[0018] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Please refer to Figures 1-8, the present invention provides a technical solution: a high-speed rolling mill for cold-rolled ribbed steel bars, comprising: a bottom plate 1, a diameter-reducing housing 2 and a forming housing 3. When the cold-rolled ribbed steel bars pass through the diameter-reducing housing 2, the surface of the cold-rolled ribbed steel bars is polished to improve the quality of the cold-rolled ribbed steel bars. A plurality of support legs 4 are uniformly and fixedly installed at the lower end of the bottom plate 1, and the support legs 4 support the bottom plate 1. The diameter-reducing housing 2 is fixed to one side of the upper end of the bottom plate 1, and the forming housing 3 is fixed to the other side of the upper end of the bottom plate 1. An outer shell 8 is fixedly installed at the upper end of the bottom plate 1, and the outer shell 8 is located between the diameter-reducing housing 2 and the forming housing 3. The outer shell 8 is U-shaped, and both sides of the bottom end of the outer shell 8 are fixedly installed on the upper end of the bottom plate 1. A rotating cylinder 9 is rotatably connected inside the outer shell 8. Large bearings 10 are fixedly sleeved on the outer walls on the front and rear sides of the rotating cylinder 9. The inner wall of the large bearing 10 is fixedly connected to the outer wall of the rotating cylinder 9. Fixed columns 11 are symmetrically and fixedly installed on the outer walls of the large bearings 10, and the outer ends of the fixed columns 11 are fixed to the inner wall of the outer shell 8. The rotating cylinder 9 can rotate inside the outer shell 8 through the large bearings 10. A toothed ring 25 is fixedly installed on the outer wall of the middle part of the large bearing 10. A protective shell 26 is fixedly installed at the upper end of the outer shell 8 and a rotating hole is provided. The protective shell 26 is located outside the rotating hole and covers the rotating hole. A second gear 28 is rotatably connected inside the rotating hole through a rotating shaft. A first gear 27 is rotatably connected inside the protective shell 26 through a rotating shaft. A second motor 29 is fixedly installed on the outer wall of one end of the protective shell 26. The output end of the second motor 29 is fixedly connected to the rotating shaft on one side of the first gear 27 through a coupling. When the second motor 29 is started, it can drive the first gear 27 to rotate. The lower outer wall of the second gear 28 is meshed with the outer wall of the toothed ring 25, and the upper outer wall of the second gear 28 is meshed with the outer wall of one end of the first gear 27. When the first gear 27 rotates, it will drive the second gear 28 to rotate. When the second gear 28 rotates, it will drive the rotating cylinder 9 to rotate inside the outer shell 8 through the toothed ring 25.

[0020] Specifically, by starting the second motor 29 to drive the first gear 27 to rotate, the first gear 27 drives the toothed ring 25 through the second gear 28 to drive the rotating cylinder 9 to rotate inside the outer shell 8.

[0021] A conveyor belt 14 is installed outside the bottom plate 1, and the conveyor belt 14 passes through the rotating cylinder 9. A debris collection bucket 7 is placed on the lower side of one end of the conveyor belt 14. A first through hole 5 is provided on one side of the upper end of the bottom plate 1, and a second through hole 6 is provided on the other side of the upper end. The aperture of the second through hole 6 is larger than that of the first through hole 5. Support plates 12 are fixedly installed on the front and rear sides of the upper and lower ends of the first through hole 5 and the second through hole 6. The support plates 12 are respectively fixed to the upper and lower ends of the bottom plate 1. Driving rollers 13 are rotatably connected between adjacent two support plates 12. A first motor 15 is fixedly installed on the outer wall of one of the support plates 12. The output end of the first motor 15 is fixedly connected to one end of one of the driving rollers 13. When the first motor 15 is started, it can drive the driving roller 13 to rotate. The conveyor belt 14 is drivingly connected to the outer ends of the four driving rollers 13, and the debris collection bucket 7 is located at the lower end of the second through hole 6.

[0022] Specifically, after the cold-rolled ribbed steel bar passes through the diameter-reducing housing 2, it then passes through the outer housing 8 and the forming housing 3. The cold-rolled ribbed steel bar is located at the upper end of the conveyor belt 14. After being ground and reduced in diameter in the diameter-reducing housing 2, the cold-rolled ribbed steel bar enters the outer housing 8. The debris ground off can fall on the conveyor belt 14. When the first motor 15 starts, it drives the driving roller 13 to drive the conveyor belt 14 to move, and conveys the fallen debris into the debris collection bucket 7.

[0023] The other end of the rotating cylinder 9 is slidably connected with a knocking component. The knocking component includes a first sliding hole 16, a fixing plate 17 and a stop rod 30. The stop rod 30 is in an L shape. One end of the stop rod 30 is fixed on the inner wall of one end of the outer housing 8, and the other end of the stop rod 30 is inserted into the rotating cylinder 9. The end of the stop rod 30 inserted into the rotating cylinder 9 is located on one side of the circular upper end of the rotating cylinder 9. There are two first sliding holes 16, and they are symmetrically arranged on the side wall of one end of the rotating cylinder 9. There are two fixing plates 17, and a second sliding hole 18 is formed on the side wall of each fixing plate 17. The fixing plates 17 are fixed on the outer wall of the rotating cylinder 9 by bolts. The lower port of the second sliding hole 18 coincides with the upper port of the first sliding hole 16, so that the second sliding hole 18 is communicated with the first sliding hole 16.

[0024] A sliding plate 19 is slidably connected in the second sliding hole 18 and the first sliding hole 16. The upper end of the sliding plate 19 is fixedly installed with a top plate 21. The top plate 21 is vertically arranged at the upper end of the sliding plate 19. The top plate 21 and the sliding plate 19 are combined into a T shape. The lower end of the sliding plate 19 slidably passes through the first sliding hole 16 and the second sliding hole 18 and is fixedly installed with an elastic metal plate 20. The elastic metal plate 20 is located inside the rotating cylinder 9. When the sliding plate 19 slides in the first sliding hole 16 and the second sliding hole 18, it drives the elastic metal plate 20 to move inside the rotating cylinder 9.

[0025] Fixed sleeves 23 are fixedly sleeved on the front and rear sides of the left and right ends of the top plate 21. Guide rollers 24 are rotatably connected to the left and right sides of the top plate 21 through shaft rods 22. The shaft rods 22 are in a U shape. The two ends of the shaft rods 22 are respectively fixedly connected to the outer walls of the two fixed sleeves 23, so that the guide rollers 24 are rotatably installed at the left and right ends of the top plate 21. And the radius of the guide rollers 24 is greater than the thickness of the top plate 21. Springs 40 are fixedly installed on the left and right sides of the lower end of the top plate 21. The lower ends of the springs 40 are fixedly installed on the upper end of the fixing plate 17. The top plate 21 can drive the sliding plate 19 to slide in the first sliding hole 16 and the second sliding hole 18 by squeezing the springs 40. When the sliding plate 19 moves, it drives the elastic metal plate 20 to move. When the springs 40 are in a balanced state, the elastic metal plate 20 does not contact the stop rod 30. When the guide rollers 24 are located at the upper and lower ends of the outer housing 8, the guide rollers 24 do not contact the inner wall of the upper end of the outer housing 8 and the upper side wall of the bottom plate 1. When the guide rollers 24 rotate to the left and right ends of the outer housing 8, the guide rollers 24 contact the inner walls of the left and right ends of the outer housing 8, and the springs 40 are in a compressed state. The elastic metal plate 20 passes over the stop rod 30 through elastic deformation.

[0026] Specifically, when the second motor 29 drives the rotating cylinder 9 to rotate, the rotating cylinder 9 drives the elastic top plate 21, the sliding plate 19 and the elastic metal plate 20 to rotate synchronously with the rotating cylinder 9. The guide roller 24 rotates together with the top plate 21. When the top plate 21 rotates to the left and right sides of the outer shell 8, the guide roller 24 is rotatably connected to the inner wall of the outer shell 8 and is pushed inward by the outer shell 8 at the same time. The top plate 21 drives the sliding plate 19 to move inward through the compression spring 40. The distance that the elastic metal plate 20 extends into the rotating cylinder 9 is greater than the radius of the rotating cylinder 9. When the elastic metal plate 20 rotates with the rotating cylinder 9, it will contact one end of the stop rod 30. As the rotation continues, the elastic metal plate 20 crosses the stop rod 30 through deformation. When crossing the stop rod 30, it impacts the cold-rolled ribbed steel bar, and shakes off the debris attached to the surface of the cold-rolled ribbed steel bar onto the conveyor belt 14. The conveyor belt 14 conveys the debris into the debris collection bucket 7. The length of the elastic metal plate 20 is less than the straight-line distance between the edge of the conveyor belt 14 and the inner wall of the rotating cylinder 9. Therefore, after the elastic metal plate 20 crosses the stop rod 30 and impacts the cold-rolled ribbed steel bar, it will not contact the conveyor belt 14.

[0027] One end of the rotating cylinder 9 is fixedly installed with a static elimination component. The static elimination component includes a fixing ring 32 and a static elimination brush 33. The static elimination brush 33 is an ordinary daily static elimination brush. When the cold-rolled ribbed steel bar passes through the static elimination brush 33, the bristles of the static elimination brush 33 sweep across the surface of the cold-rolled ribbed steel bar, thereby sweeping off the powdery debris adsorbed on the surface of the cold-rolled ribbed steel bar. Two support rods 31 are symmetrically and fixedly installed at the outer end of the fixing ring 32. The fixing ring 32 is located inside one end of the rotating cylinder 9, and the end of the support rod 31 away from the fixing ring 32 is fixed on the inner wall of the rotating cylinder 9, fixing the fixing ring 32 on one side of the inner end of the rotating cylinder 9. The static elimination brush 33 is in a circular ring shape. An elastic clamping plate 34 is fixedly installed on the outer wall of one end of the static elimination brush 33. The elastic clamping plate 34 is in an L shape. One end of the elastic clamping plate 34 is fixed on the side wall of the static elimination brush 33, and a limiting block 35 is fixedly installed on the inner side of the other end. The other end of the elastic clamping plate 34 passes through the outer end of the fixing ring 32 and clamps on the outer wall of the fixing ring 32, and the limiting block 35 is clamped on the outer end of the fixing ring 32 to fix the elastic clamping plate 34. At the same time, the static elimination brush 33 is located inside the fixing ring 32. When it is necessary to replace the static elimination brush 33, push one end of the elastic clamping plate 34 upward. One end of the elastic clamping plate 34 drives the limiting block 35 to tilt upward and separates the limiting block 35 from the fixing ring 32, and then the static elimination brush 33 can be taken out of the fixing ring 32, which is convenient for replacing the static elimination brush 33.

[0028] Specifically, the cold-rolled ribbed steel bar passes through the static eliminator brush 33. The cold-rolled ribbed steel bar passes through the knocking component, which can shake off large debris attached to the outer wall of the cold-rolled ribbed steel bar. Under the action of static electricity, there will also be powdery debris adsorbed on the surface of the cold-rolled ribbed steel bar. When the cold-rolled ribbed steel bar passes through the static eliminator brush 33, the bristles of the static eliminator brush 33 sweep across the surface of the cold-rolled ribbed steel bar, thereby sweeping off the powdery debris adsorbed on the surface of the cold-rolled ribbed steel bar.

[0029] On one side of the upper end of the housing 8, a support column 36 is fixedly installed. At the lower end of the support column 36, a mounting plate 37 is fixedly installed. At the lower end of the mounting plate 37, a water spray head 39 is installed through a connecting pipe 38. The water spray head 39 is located above the cold-rolled ribbed steel bar. The connecting pipe 38 is connected to an external water delivery pipe to deliver water source into the water spray head 39 and then spray it onto the cold-rolled ribbed steel bar to clean the surface of the cold-rolled ribbed steel bar.

[0030] During actual use, after the cold-rolled ribbed steel bar passes through the diameter-reducing housing 2, it then passes through the housing 8 and the forming housing 3. The cold-rolled ribbed steel bar is located above the conveyor belt 14. After being ground and reduced in diameter in the diameter-reducing housing 2, the cold-rolled ribbed steel bar enters the housing 8. The debris ground off can fall onto the conveyor belt 14. The first motor 15 starts to drive the driving roller 13 to drive the conveyor belt 14 to move, conveying the fallen debris to the debris collection bucket 7. At the same time, the second motor 29 drives the rotating cylinder 9 to rotate. The rotating cylinder 9 drives the elastic top plate 21, the sliding plate 19, and the elastic metal plate 20 to rotate synchronously with the rotating cylinder 9. The guiding roller 24 rotates together with the top plate 21. When the top plate 21 rotates to the left and right sides of the housing 8, the guiding roller 24 is rotationally connected to the inner wall of the housing 8 and is simultaneously pushed inward by the housing 8. The top plate 21 drives the sliding plate 19 to move inward through the compression spring 40. The distance that the elastic metal plate 20 extends into the rotating cylinder 9 is greater than the radius of the rotating cylinder 9. When the elastic metal plate 20 rotates with the rotating cylinder 9, it will contact one end of the stop bar 30. As the rotation continues, the elastic metal plate 20 passes over the stop bar 30 through deformation. When passing over the stop bar 30, it impacts the cold-rolled ribbed steel bar, shaking off the debris attached to the surface of the cold-rolled ribbed steel bar onto the conveyor belt 14. The conveyor belt 14 conveys the debris to the debris collection bucket 7. The cold-rolled ribbed steel bar passes through the knocking component, which can shake off large debris attached to the outer wall of the cold-rolled ribbed steel bar. Under the action of static electricity, there will also be powdery debris adsorbed on the surface of the cold-rolled ribbed steel bar. When the cold-rolled ribbed steel bar passes through the static eliminator brush 33, the bristles of the static eliminator brush 33 sweep across the surface of the cold-rolled ribbed steel bar, thereby sweeping off the powdery debris adsorbed on the surface of the cold-rolled ribbed steel bar. Finally, the cold-rolled ribbed steel bar passes through the lower end of the water spray head 39, and the water spray head 39 sprays water onto the cold-rolled ribbed steel bar to clean the surface of the cold-rolled ribbed steel bar.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
