Description

Technical Field

[0001] This utility model relates to the field of steel bar production and processing technology, and in particular to a steel bar bending adjuster. Background Technology

[0002] Steel bars are typically made of carbon steel or alloy steel. Carbon steel is mainly composed of carbon and iron, while alloy steel may contain other elements such as chromium, nickel, and molybdenum to give the steel stronger properties. Steel bars are widely used in building structures, bridges, roads, machinery manufacturing, automobile manufacturing, and other fields. In construction, reinforcing bars (a special type of steel bar) are often used in concrete structures to enhance the strength and durability of the concrete. However, reinforcing bars often need to be bent into specific shapes to fit the curves or bends in the structure. This bending can enhance the strength and durability of the concrete structure, but the bending process may cause slight deviations in the dimensions of the steel bars. Adjustment ensures that the bent steel bars meet the design specifications and precision requirements, for which a steel bar bending adjuster is needed.

[0003] A steel bar bending adjuster is a device used to adjust the bending of steel bars during the bending process. In the use of traditional steel bar bending adjusters, most of them cannot be used to bend steel bars of different sizes. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a steel bar bending adjuster, which aims to improve the problem that the steel bar bending adjuster cannot be used for bending different types of steel bars.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel bar bending adjuster, comprising a worktable, a rotating rod rotatably connected inside the worktable, a handle fixedly connected to the bottom end of the rotating rod, a first rotating rod fixedly connected to the top end of the rotating rod, a first rotating shaft rotatably connected inside the first rotating rod, a second rotating rod fixedly connected to the outer wall of the first rotating shaft, a second rotating shaft rotatably connected inside the second rotating rod, a sliding plate fixedly connected to the top end of the second rotating shaft, the lower surface of the sliding plate slidably connected to the upper surface of the worktable, a first support plate fixedly connected to the upper surface of the worktable, a first rotating roller rotatably connected inside the first support plate, a limit post fixedly connected to the inner wall of the first support plate, the sliding plate slidably connected to the outer wall of the limit post, a support column fixedly connected to the upper surface of the sliding plate, a collar fixedly connected to the upper surface of the support column, the inner wall of the collar slidably connected to the outer wall of the first rotating roller, and a fixing component disposed inside the rotating rod.

[0006] Furthermore, the fixing component includes a threaded groove formed inside the rotating rod, and a nut is provided on the outer wall of the rotating rod, with the inner wall of the nut threadedly connected to the inner wall of the threaded groove.

[0007] Furthermore, a second support plate is fixedly connected to the upper surface of the workbench, and a top plate is fixedly connected to the upper surface of the second support plate.

[0008] Furthermore, a first hydraulic cylinder is fixedly connected to the lower surface of the top plate, and a first fixing plate is fixedly connected to the output end of the first hydraulic cylinder.

[0009] Furthermore, a second fixing plate is fixedly connected to the lower surface of the first fixing plate, and a first rotating shaft is rotatably connected inside the second fixing plate.

[0010] Furthermore, a connecting rod is fixedly connected to the outer wall of the first rotating shaft, a third fixing plate is fixedly connected to the outer wall of the connecting rod, and a second rotating shaft is rotatably connected to the inside of the third fixing plate.

[0011] Furthermore, a second hydraulic cylinder is fixedly connected to the outer wall of the first rotating shaft, and the output end of the second hydraulic cylinder is fixedly connected to the outer wall of the second rotating shaft.

[0012] Furthermore, a bracket is fixedly connected to the outer wall of the connecting rod, a fixed column is fixedly connected to the inner wall of the bracket, and a second rotating roller is rotatably connected to the outer wall of the fixed column.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the rotating handle drives the first rotating rod to rotate inside the worktable via the rotating rod. When the first rotating rod rotates, it drives the second rotating rod to rotate via the first rotating shaft. When the second rotating rod rotates, it drives the slide plate to slide on the outer wall of the limiting post via the second rotating shaft. When the slide plate slides, it drives the collar to slide on the outer wall of the first rotating roller via the support post, thereby adjusting the application range of the first rotating roller and achieving the effect of bending different types of steel bars.

[0015] 2. In this utility model, when the second rotating rod drives the second rotating shaft to move inside the worktable, it will cause the slide plate to slide on the outer wall of the limiting post on the inner wall of the first support plate. The movement of the slide plate will cause the support post on the upper surface to drive the collar to slide on the outer wall of the first rotating roller. When it slides to the appropriate position, the rotating nut rotates on the inner wall of the threaded groove, which increases the friction between the rotating rod and the worktable and fixes the rotating rod. This can achieve the effect of fixing the collar on the outer wall of the first rotating roller, preventing the steel bar from shifting during the bending process and causing bending failure.

[0016] 3. In this utility model, starting the second hydraulic cylinder drives the second rotating shaft at the output end to move. When the second rotating shaft moves, the third fixed plate will drive the connecting rod to move simultaneously. When the second rotating shaft moves, it will rotate inside the second fixed plate through the first rotating shaft, causing the connecting rod to drive the bracket to move simultaneously. When the bracket moves, the fixed column will drive the second rotating roller to move simultaneously. By moving the position of the second rotating roller, the bending effect of adjusting the steel bar at different distances can be achieved. Attached Figure Description

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 protection scope of the present utility model.

A first rotating roller 10 is rotatably connected inside a support plate 9. A limit post 11 is fixedly connected to the inner wall of the first support plate 9. The inner wall of the slide plate 8 is slidably connected to the outer wall of the limit post 11. A support post 12 is fixedly connected to the upper surface of the slide plate 8. A collar 13 is fixedly connected to the upper surface of the support post 12. The inner wall of the collar 13 is slidably connected to the outer wall of the first rotating roller 10. A fixing component is provided inside the rotating rod 2. The fixing component includes a threaded groove 14, which is opened inside the rotating rod 2. A nut 15 is provided on the outer wall of the rotating rod 2. The inner wall of the nut 15 is threadedly connected to the inner wall of the threaded groove 14.

[0025] Specifically, rotating the handle 3 can drive the first rotating rod 4 to rotate inside the worktable 1 via the rotating rod 2. When the first rotating rod 4 rotates, it can drive the second rotating rod 6 to rotate via the first rotating shaft 5. When the second rotating rod 6 rotates, it can drive the slide plate 8 to slide on the outer wall of the limiting post 11 via the second rotating shaft 7. The limiting post 11 can prevent the slide plate 8 from deviating during the sliding process. By sliding the slide plate 8, the support post 12 can drive the collar 13 to adjust the application range of the first rotating roller 10. Rotating the nut 15 on the inner wall of the threaded groove 14 can increase the friction between the worktable 1 and the rotating rod 2 to fix the rotating rod 2.

[0026] Reference Figure 4 A second support plate 16 is fixedly connected to the upper surface of the workbench 1, and a top plate 17 is fixedly connected to the upper surface of the second support plate 16; a first hydraulic cylinder 18 is fixedly connected to the lower surface of the top plate 17, and a first fixed plate 19 is fixedly connected to the output end of the first hydraulic cylinder 18.

[0027] Specifically, the second support plate 16 supports the top plate 17, and the top plate 17 fixes the first hydraulic cylinder 18. The first hydraulic cylinder 18 can push the first fixing plate 19 to move downward.

[0028] Reference Figure 4A second fixed plate 20 is fixedly connected to the lower surface of the first fixed plate 19, and a first rotating shaft 21 is rotatably connected inside the second fixed plate 20; a connecting rod 22 is fixedly connected to the outer wall of the first rotating shaft 21, a third fixed plate 23 is fixedly connected to the outer wall of the connecting rod 22, and a second rotating shaft 24 is rotatably connected inside the third fixed plate 23; a second hydraulic cylinder 25 is fixedly connected to the outer wall of the first rotating shaft 21, and the output end of the second hydraulic cylinder 25 is fixedly connected to the outer wall of the second rotating shaft 24; a bracket 26 is fixedly connected to the outer wall of the connecting rod 22, a fixed column 27 is fixedly connected to the inner wall of the bracket 26, and a second rotating roller 28 is rotatably connected to the outer wall of the fixed column 27;

[0029] Specifically, the second hydraulic cylinder 25 can cause the second rotating shaft 24 to move the connecting rod 22 through the third fixed plate 23. When the connecting rod 22 moves, it can rotate inside the second fixed plate 20 through the first rotating shaft 21. When the connecting rod 22 rotates, the use position of the fixed column 27 and the second rotating roller 28 will be adjusted through the bracket 26.

[0030] Working principle: When the device is needed, the steel bar to be bent is placed on the outer wall of the first rotating roller 10. Rotating the handle 3 drives the rotating rod 2 to rotate inside the worktable 1. As the rotating rod 2 rotates, it simultaneously drives the first rotating rod 4 on the upper surface to rotate inside the worktable 1. The rotation of the first rotating rod 4 drives the second rotating rod 6 to move simultaneously via the internal first rotating shaft 5. The movement of the second rotating rod 6 drives the slide plate 8 to slide on the upper surface of the worktable 1 via the internal second rotating shaft 7. The limiting post 11 on the outer wall of the first support plate 9 prevents the slide plate 8 from deviating during sliding. The sliding effect is that when the slide plate 8 slides, the support column 12 on the upper surface drives the collar 13 to rotate on the outer wall of the first rotating roller 10 inside the first support plate 9. By sliding the collar 13, the application range of the first rotating roller 10 can be adjusted according to different types of steel rods. When adjusted to a suitable position, the rotating nut 15 rotates on the inner wall of the threaded groove 14 inside the rotating rod 2, so that the nut 15 can increase the friction between the rotating rod 2 and the worktable 1, thereby fixing the rotating rod 2 to prevent rotation. At the same time, the collar 13 is also fixed on the outer wall of the first rotating roller 10. After being fixed, the collar 13 can also achieve the effect of... During the bending process of the steel bar, to prevent the steel bar from shifting and causing bending failure, the second hydraulic cylinder 25 is activated to move the second rotating shaft 24 at the output end. As the second rotating shaft 24 moves, it drives the connecting rod 22 to move simultaneously via the third fixed plate 23 on the outer wall. While moving, the connecting rod 22 rotates within the second fixed plate 20 via the internal first rotating shaft 21. Simultaneously, the support 26 moves to adjust its position. As the support 26 moves, it drives the second rotating roller 28 to move via the internal fixed column 27, thereby adjusting the bending position and preventing bending failure. To achieve the same bending effect, the first hydraulic cylinder 18 is activated to push the first fixed plate 19 at the output end to move downward, which will drive the second rotating roller 28 to bend the steel bar on the upper surface of the first rotating roller 10. By rotating the second rotating roller 28 on the outer wall of the fixed column 27 and rotating the first rotating roller 10 inside the first support plate 9, the bending work can be made more labor-saving. This device can not only be used for steel bars of different types, but also prevent the steel bar from deviating during use, which would cause errors in the bending work. It can also adjust different positions to achieve different bending effects on the steel bar.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
