[0002] Construction engineering refers to the planning, surveying, design, construction, and completion of various technical work and completed engineering entities for the construction, renovation, or expansion of buildings and ancillary structures and facilities, as well as the installation of supporting lines, pipelines, and equipment. During the construction process, it is necessary to bend the steel bars in the building, so a steel bar bending machine is required.

[0003] Existing rebar bending machines suffer from the problem that the protective coating on the surface of the rebars deforms and peels off after bending. This peeling material accumulates on the processing turntable, affecting subsequent rebar bending. Furthermore, rebars bent at large angles are difficult to remove from the processing table. Therefore, we propose a rebar bending machine to solve the problems mentioned above. Summary of the Invention

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.

[0022] Please see Figure 1-6This utility model provides a technical solution: a rebar bending machine, including a housing 1, a first servo motor 9, and a suction pump 18. Transmission wheel cylinders 2 are installed at both ends of the upper part of the housing 1, and a fixed plate 3 is fixedly installed on one side of the upper part of the housing 1. A limit block 4 is fixed above the middle part of the fixed plate 3. A first groove 5 is formed on the upper surface of one side of the fixed plate 3. A first adjusting screw 6 is rotatably connected inside the first groove 5 on the upper surface of the fixed plate 3, and a first locking block 8 is provided on the first groove 5. The first adjusting screw 6 and the first locking block 8 are connected by a threaded connection, and the first locking block 8 and the first groove 5 on the surface of the limit block 4 form a locking sliding connection. A support plate 7 above the first locking block 8 is parallel to the limit block 4, and the right end face of the limit block 4 is flush with the right end face of the central shaft 11. The lower end face of the support plate 7 is flush with the upper end face of the turntable 10, facilitating the threaded movement of the first locking block 8 by the first adjusting screw 6, so that the first locking block 8 can move on the surface of the fixed plate 3. The first groove 5 slides on the support plate 7, which can adapt to the support of steel bars of different sizes. The support plate 7 is fixed above the first locking block 8. The first servo motor 9 is fixed in the middle of the lower part of the chassis 1. The output end of the first servo motor 9 is fixed to the turntable 10, and the central shaft 11 is fixed in the middle of the turntable 10. The surface of the turntable 10 is provided with a second groove 12, and the interior of the second groove 12 is rotatably connected to a second adjusting screw 13 protruding from the outside of the turntable 10. The surface of the second adjusting screw 13 is provided with a second locking block 14, and the upper part of the second locking block 14 is fixed with a movable extrusion wheel 15. The connection between the second adjusting screw 13 and the second locking block 14 is a threaded connection, and the second locking block 14 and the second groove 12 on the surface of the turntable 10 form a locking sliding connection. The second locking block 14 can be driven by the second adjusting screw 13 to move threadedly, so that the second locking block 14 can drive the movable extrusion wheel 15 to slide on the surface of the turntable 10, which makes it convenient for the device to adapt to steel bars of different sizes.

[0023] Please see Figure 1-6The surface of the turntable 10 has an opening 16, and a guide pipe 17 that penetrates the surface of the turntable 10 is connected inside the opening 16. The other end of the guide pipe 17 passes through the housing 1 and is connected to a suction pump 18 fixed inside the housing 1. The other end of the suction pump 18 is connected to a discharge pipe 19, and the end of the discharge pipe 19 is connected to a collection box 20 fixed inside the housing 1. A waste removal frame 21 located on the surface of the housing 1 is slidably installed inside the collection box 20 to facilitate the absorption of protective layer waste that has fallen from the bent steel bars through the opening 16 and the guide pipe 17, and discharge it into the collection box 20 so that it can be discharged from the waste removal frame 21. A top material assembly 22 is installed inside the housing 1. The top material assembly 22 includes a second servo motor 2201. The motor 2201 is fixed on the upper inner side of the housing 1. The output end of the second servo motor 2201 is fixed with a rotating lead screw 2202. The surface of the rotating lead screw 2202 is threadedly connected to a lifting plate 2203. Movable rods 2204 are fixed at both ends of the lifting plate 2203. A top plate 2205 is fixed above the movable rods 2204, which facilitates the threaded movement of the lead screw 2202 and the lifting plate 2203, so that the lifting plate 2203 drives the movable rods 2204 to slide on the housing 1. The top plate 2205 is U-shaped. The movable rods 2204 below the top plate 2205 are slidably connected to the upper surface of the housing 1, so that when the movable rods 2204 slide, the top plate 2205 can discharge the bent steel bars, so that the device can automatically discharge materials.

[0024] Working principle: First, when in use, the steel bar is placed between the central shaft 11 and the movable extrusion wheel 15 on the turntable 10 and rests on the fixed plate 3. Then, by rotating the first adjusting screw 6, the first adjusting screw 6 moves threadedly with the first locking block 8 inside the first groove 5 on the surface of the fixed plate 3, so that the first locking block 8 drives the upper support plate 7 to slide, so that the support plate 7 cooperates with the limiting block 4 to limit and support the steel bar. Then, by rotating the second adjusting screw 13, the second adjusting screw 13 drives the second locking block 14 to move threadedly on the second groove 12 on the surface of the turntable 10, so that the movable extrusion wheel 15 above the second locking block 14 moves towards the center of the turntable 10, so that the steel bar is limited. When bending, the first servo motor 9 can be turned on, so that the first servo motor 9 drives the turntable 10 to rotate, so that the movable extrusion wheel 15 on the upper surface of the turntable 10 drives the steel bar to bend, so that the steel bar can be bent.

[0025] When the steel bar is bent, the suction pump 18 can be turned on so that the guide pipe 17 and the opening 16 can absorb the debris that falls off the protective layer of the steel bar during the bending process and discharge it into the collection box 20. It is convenient to discharge the waste residue of the protective layer of the steel bar by pulling the dirty frame 21, so as to avoid the waste residue of the protective layer remaining on the turntable 10 and affecting the subsequent processing work.

[0026] When removing the bent steel bar, the second servo motor 2201 on the top material assembly 22 can be turned on, so that the second servo motor 2201 drives the lifting plate 2203 to move threadedly by rotating the lead screw 2202. In this way, the lifting plate 2203 drives the top material plate 2205 to move upward through the movable rod 2204, so that the top material plate 2205 pushes out the bent steel bar. This is the working principle of the steel bar bending machine.

[0027] Although the present invention 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 invention should be included within the protection scope of the present invention.
