Technical Field

[0001] This utility model relates to the field of surface treatment technology for cold-drawn steel, specifically to a shot blasting device for surface treatment of cold-drawn steel. Background Technology

[0002] Shot blasting is a key process in the surface treatment of cold-drawn steel sections. It is usually carried out after the steel sections have been cold-drawn and before subsequent processing steps such as painting and welding. In the production process of cold-drawn steel sections, after the steel is cold-drawn to obtain the required shape and size, impurities such as oxide scale and rust will be generated on the surface. Shot blasting can effectively remove these impurities. However, traditional shot blasting equipment can generally only blast one side of the steel. Usually, all four sides of the steel need to be shot blasted, so the steel needs to be flipped multiple times to complete a set of shot blasting processes, resulting in low processing efficiency.

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1-6 This utility model provides a technical solution: a shot blasting device for surface treatment of cold-drawn steel, including a protective chamber 1, a feeding pipe 2 fixedly connected to the back of the protective chamber 1, a storage box 3 fixedly connected to the bottom of the feeding pipe 2 passing through the protective chamber 1, and a shot blasting machine 4 fixedly installed at the bottom of the storage box 3, with the shot blasting machine 4 built inside the protective chamber 1. A processing chamber 5 is opened on the inner side of the protective chamber 1, and a shot blasting port 6 is opened on the side of the processing chamber 5, which is connected to the output end of the shot blasting machine 4. An inclined groove 9 is provided at the bottom of the processing chamber 5, and a separator 10 is fixedly installed on the back of the processing chamber 5, and the separator 10 is connected to the side of the inclined groove 9. The connection between the inclined groove 9 and the separator 10 can filter and recycle the shot after shot blasting, thereby recycling and reusing the shot, reducing the cost of shot loss, and improving resource utilization.

[0021] A connecting plate 7 is fixedly installed on the side of the processing chamber 5. A chuck 8 is fixedly installed on the side of the connecting plate 7. A rotary traction component is slidably arranged on the inner side of the chuck 8. A drive motor 11 is fixedly installed on the side of the connecting plate 7. An active rotating shaft 12 is fixedly arranged at the output end of the drive motor 11. The active rotating shaft 12 is meshed with the rotary traction component. The rotary traction component includes a rotating wheel 13. Rotating teeth are arranged on the circumferential side of the rotating wheel 13. The rotating wheel 13 is meshed with the active rotating shaft 12 through the rotating teeth. The drive motor 11 drives the active rotating shaft 12 to rotate. The active rotating shaft 12 drives the rotating wheel 13 to rotate in the chuck 8 through the meshing of the rotating teeth. This provides the component rotation function. The structure is simple and the design is reasonable.

[0022] A fixed rod 14 is fixedly connected to the inner circumference of the rotating wheel 13. A movable rod 15 is rotatably connected to the side of the fixed rod 14. A transmission connecting rod 16 is fixedly installed on the side of the movable rod 15. A drive roller 17 is rotatably connected to the bottom of the transmission connecting rod 16. A reduction motor 18 for rotating the drive roller 17 is fixedly connected to the side of the transmission connecting rod 16. A slot 19 is provided on the side of the transmission connecting rod 16. By utilizing the characteristic of the movable rod 15 rotating on the side of the fixed rod 14, the drive roller 17 can complete the lifting and lowering operation in the vertical and horizontal directions. The two sets of drive rollers 17 cooperate to clamp and connect cold-drawn steel of different sizes. The structure is simple and improves the applicability of the equipment.

[0023] A sleeve 20 is fitted onto the side of the fixing rod 14. A retaining ring 21 is fixedly installed on the side of the sleeve 20, and the retaining ring 21 slides in conjunction with the retaining groove 19. A compression spring 22 is fixedly installed at the end of the sleeve 20 away from the retaining ring 21.

[0024] By using the snap ring 21 and the slot 19 to engage, the movable rod 15 with the slot 19 can only rotate in one direction under the restriction of the snap ring 21, which prevents the movable rod 15 from rotating in the opposite direction, thus avoiding loosening or even falling off the clamping steel and improving the stability of the equipment operation.

[0025] A threaded rod 23 is fixedly installed on the side of the rotating wheel 13. A movable rod 24 is slidably arranged on the side of the threaded rod 23. A side pressure plate 25 is fixedly connected to the side of the movable rod 24. A pressure roller 26 is arranged on the side of the side pressure plate 25. An adjusting drum 27 is rotatably connected to the side of the movable rod 24. The adjusting drum 27 is threadedly engaged with the threaded rod 23. Through the engagement with the threaded rod 23, the adjusting drum 27 can drive the side pressure plate 25 to slide on the side of the threaded rod 23, thereby adjusting the distance between the side pressure plates 25. In conjunction with the structure of the drive roller 17, it can perform comprehensive clamping and restriction of the steel profile in all directions, improving the stability of the steel profile conveying process.

[0026] In use, firstly, the steel profile to be processed is inserted into the inlet of the rotating inner ring. Then, utilizing the characteristic of the movable rod 15 rotating on the side of the fixed rod 14, the movable rod 15 drives the drive roller 17 at the bottom of the transmission connecting rod 16 to perform lifting and lowering operations in the vertical and horizontal directions. The two sets of drive rollers 17 cooperate to clamp and connect cold-drawn steel profiles of different sizes. The retaining ring 21 and the retaining groove 19 are engaged, so that the movable rod 15 with the retaining groove 19 can only rotate in one direction under the restriction of the retaining ring 21, preventing the movable rod 15 from rotating in the opposite direction. Then, by rotating the adjusting drum 27, which is engaged with the threaded rod 23, the side pressure plate 25 can be driven to slide on the side of the threaded rod 23, thereby achieving the function of adjusting the distance between the side pressure plates 25. This works in conjunction with the drive roller 17. The structure allows for comprehensive clamping and restriction of the steel profile in all directions. Finally, the drive motor 11 and reduction motor 18 are activated. The reduction motor 18 drives the drive roller 17 to rotate. The drive roller 17, through friction with the surface of the cold-drawn steel profile, moves the cold-drawn steel profile within the working chamber. The drive motor 11 drives the active rotating shaft 12 to rotate. The active rotating shaft 12, through gear meshing, drives the rotating wheel 13 to rotate within the chuck 8, providing the component rotation function and achieving the effect of rotating and traction of the cold-drawn steel profile. Within the working chamber, the cold-drawn steel profile undergoes comprehensive shot blasting treatment by the shot blasting machine 4. Finally, the completed cold-drawn steel profile slides out from the rotating traction component at the other end of the working chamber, and the ejected shot falls into the inclined chute 9 and flows into the separator 10. The shot blasted shot is filtered and recycled, thus enabling shot recycling and reuse.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
