Description

Technical Field

[0001] This utility model relates to the field of extrusion profile technology, specifically to a descaling device for the inner hole of an extruded billet. Background Technology

[0002] Extruded billets refer to the raw materials used in the extrusion forming process of metallic or non-metallic materials. These raw materials are usually pre-processed to form billets of a certain shape and size to facilitate subsequent extrusion processing. During the extrusion production process, due to the interaction of temperature, pressure and materials, rust, oxide film and other defects may appear on the surface of the billet. These defects are collectively referred to as "scales". The presence of these scales not only reduces the mechanical properties of the material, but may also lead to serious problems in subsequent processing, such as cracks or higher processing costs.

[0003] In existing processes for descaling the inner holes of extruded billets, descaling the outer surface of the billet is relatively easy, while descaling the inner holes is more difficult, especially for inner holes with a diameter of less than 400 mm. To date, there is no good method for achieving complete descaling of these inner holes. Typically, manual descaling using cutting tools is employed. This method not only may result in incomplete descaling but also involves high labor intensity, thus reducing the efficiency and quality of inner hole descaling and increasing labor costs. Therefore, we propose a device for descaling the inner holes of extruded billets. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, a descaling device for the inner hole of an extruded billet includes a base plate 1. A support base 2 is fixedly connected to the top of the base plate 1. A first connecting shaft 3 and a second connecting shaft 27 are rotatably connected between the inner walls of the support base 2. Two rollers 4 are fixedly connected to the outer sides of both the first connecting shaft 3 and the second connecting shaft 27. A column 14 is slidably connected to the top of the base plate 1. A displacement assembly is provided on the top of the base plate 1 to drive the column 14 to move. A connecting plate 17 is slidably connected to one side of the column 14. An adjustment assembly is provided on one side of the column 14 to drive the connecting plate 17 to move. A connecting plate 17 is rotatably connected to one side of the connecting plate 17. A descaling assembly is provided on one side of the rotating shaft 12 and the connecting plate 17. The descaling assembly is used to drive the rotating shaft 12 to rotate. A descaling brush 10 and a scraper 11 are fixedly connected to the outside of the rotating shaft 12. The scraper 11 is fixedly connected to one side of the descaling brush 10. A drive motor 28 is fixedly installed on one side of the support base 2. The output end of the drive motor 28 extends into the interior of the support base 2 and is fixedly connected to the first connecting shaft 3. A collection box 5 is fixedly connected to one side of the bottom plate 1. A collection hopper 6 is fixedly connected to the top of the collection box 5. The collection hopper 6 communicates with the collection box 5. A collection groove 23 is opened on one side of the collection box 5. A collection frame 7 is slidably connected between the inner walls of the collection groove 23.

[0024] During descaling of the inner hole of the extruded billet, the extruded billet is first placed on the support base 2. Then, the connecting plate 17 is moved to one side of the column 14 by the adjusting component, so that the height of the descaling brush 10 is adjusted according to the actual billet specifications. Next, the drive motor 28 is started by the external controller. The drive motor 28 drives the first connecting shaft 3 to rotate clockwise between the inner walls of the support base 2, so that the four rollers 4 on the first connecting shaft 3 and the second connecting shaft 27 drive the billet to rotate clockwise. At the same time, the descaling component drives the rotating shaft 12 to rotate counterclockwise on one side of the connecting plate 17, so that the descaling brush 10 and the scraper 11 rotate counterclockwise. Then, the displacement component drives the column 14 to move at a constant speed on the top of the base plate 1, so that the descaling brush 10 performs descaling work on the inside of the extruded billet. At the same time, the scraper 11 pushes the oxide scale out of the inner hole of the extruded billet. Then, the collecting hopper 6 collects the oxide scale into the inside of the collecting box 5, and collects it through the collecting frame 7 inside the collecting trough 23, thereby improving the descaling efficiency and quality of the inner hole of the extruded billet.

[0025] like Figures 1-4 As shown, the displacement assembly includes a displacement groove 8, which is opened on the top of the base plate 1. A displacement threaded rod 9 is rotatably connected between the inner walls of the displacement groove 8. A displacement block 24 is threadedly connected to the outer side of the displacement threaded rod 9. The top of the displacement block 24 is fixedly connected to the column 14. A displacement motor 13 is fixedly installed on one side of the base plate 1. The output end of the displacement motor 13 extends into the interior of the displacement groove 8 and is fixedly connected to the displacement threaded rod 9.

[0026] The displacement motor 13 drives the displacement threaded rod 9 to rotate between the inner walls of the displacement groove 8, which causes the displacement block 24 to drive the column 14 to move on the top of the base plate 1, further improving the descaling efficiency of the inner hole of the extruded billet.

[0027] like Figures 1-4 As shown, the adjustment assembly includes an adjustment groove 15, which is opened on one side of the column 14. An adjustment threaded rod 16 is rotatably connected between the inner walls of the adjustment groove 15. An adjustment block 25 is connected to the outer threaded rod of the adjustment threaded rod 16. One side of the adjustment block 25 is fixedly connected to the connecting plate 17. A turntable 21 is rotatably connected to the top of the column 14. The bottom end of the turntable 21 extends into the interior of the adjustment groove 15 and is fixedly connected to the adjustment threaded rod 16. A handle 22 is fixedly connected to the top of the turntable 21.

[0028] By pushing the handle 22 to drive the turntable 21 to rotate, the adjusting threaded rod 16 is driven to rotate between the inner walls of the adjusting groove 15, and the adjusting block 25 drives the connecting plate 17 to move on one side of the column 14, thereby improving the convenience of the descaling device.

[0029] like Figures 1-4 As shown, the descaling assembly includes a mounting plate 19, which is fixedly connected to one side of a connecting plate 17. A worm gear 18 is rotatably connected to the bottom of the mounting plate 19. One end of a rotating shaft 12 passes through the connecting plate 17 and is fixedly connected to a worm wheel 26, which meshes with the worm gear 18. A descaling motor 20 is fixedly mounted on the top of the mounting plate 19, and the output end of the descaling motor 20 passes through the mounting plate 19 and is fixedly connected to the worm gear 18.

[0030] The descaling motor 20 drives the worm gear 18 to rotate on the top of the mounting plate 19, which in turn causes the worm wheel 26 to drive the rotating shaft 12 to rotate on one side of the connecting plate 17, thereby improving the descaling quality of the descaling device.

[0031] This utility model provides a descaling device for the inner hole of an extruded billet. The specific working principle is as follows: During descaling of the inner hole of the extruded billet, the billet is first placed on the support base 2. Then, by pushing the handle 22, the turntable 21 is rotated, causing the adjusting threaded rod 16 to rotate between the inner walls of the adjusting groove 15. This causes the adjusting block 25 to move the connecting plate 17 to one side of the column 14, allowing the height of the descaling brush 10 to be adjusted according to the actual billet specifications. Next, the drive motor 28 is started using an external controller. The drive motor 28 drives the first connecting shaft 3 to rotate clockwise between the inner walls of the support base 2, causing the four rollers 4 on the first connecting shaft 3 and the second connecting shaft 27 to rotate the billet clockwise. Simultaneously... The descaling motor 20 drives the worm gear 18 to rotate on the top of the mounting plate 19, causing the worm wheel 26 to drive the rotating shaft 12 to rotate counterclockwise on one side of the connecting plate 17, which in turn drives the descaling brush 10 and the scraper 11 to rotate counterclockwise. Then, the displacement motor 13 drives the displacement threaded rod 9 to rotate between the inner walls of the displacement groove 8, causing the displacement block 24 to drive the column 14 to move at a constant speed on the top of the base plate 1, so that the descaling brush 10 can descale the inside of the extruded billet. At the same time, the scraper 11 pushes the oxide scale out of the inner hole of the extruded billet. Then, the collecting hopper 6 collects the oxide scale into the inside of the collecting box 5, and collects it through the collecting frame 7 inside the collecting groove 23. This completes the descaling work of the inner hole of the extruded billet.

[0032] 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.
