DETAILED DESCRIPTION

[0031] The technical scheme in the embodiments of the utility model will be described clearly and completely in connection with the drawings of the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary, and are used for explaining the utility model only, and cannot be understood as the limitation of the utility model.

[0032] The embodiments of the utility model will be described according to the overall structure of the utility model.

[0033] A bending device for welded wire mesh, such as Figures 1-7 As shown, the device includes an operating table 1. A bending structure is provided on one side of the operating table 1, which can be used to bend the welded wire mesh. The bending structure includes connecting rods 3 rotatably connected to both ends of the operating table 1 via rotating shafts 2. A movable block 4 is fixedly connected in the middle of a set of connecting rods 3. The top of the movable block 4 is connected to a bending roller 6 via several support blocks 5. A set of hydraulic cylinders 7 is hinged between the operating table 1 and the movable block 4. The hydraulic cylinders 7 can move the movable block 4 and the bending roller 6 through the rotating shafts 2 and connecting rods 3, thereby achieving precise bending of the welded wire mesh and making the bending process of the welded wire mesh smoother and more controllable.

[0034] Subsequently, several fixing blocks 13 are fixedly connected to the top of the operating platform 1. Each fixing block 13 has a connecting block 14 fixedly connected to its top, and the size of the connecting block 14 is larger than that of the fixing block 13. Therefore, the bottom of the connecting block 14 can limit the position of the welded wire mesh, which helps to increase the stability of the welded wire mesh when bending. Each connecting block 14 is rotatably connected to a connecting shaft 15 near the bending structure, and a movable plate 16 is fixedly connected to the surface of the connecting shaft 15. Thus, the movable plate 16 can rotate on one side of the connecting block 14 through the connecting shaft 15. A coil spring 17 is provided at the connection between each connecting shaft 15 and the corresponding connecting block 14. A set of threaded rods 18 are threadedly connected to the surface of each connecting block 14, and one end of the threaded rod 18 contacts one side of the movable plate 16. Therefore, when the threaded rod 18 is screwed on the connecting block 14, it can rotate through the threaded rod 18. The movable plate 16 is rotated to adjust the angle between it and the bending structure, adapting to different bending requirements of welded wire mesh. Due to the design of the coil spring 17, the movable plate 16 is always in contact with one end of the threaded rod 18. When the movable plate 16 is subjected to external force, the resistance of the threaded rod 18 on one side of the movable plate 16 prevents it from rotating, facilitating better bending of the welded wire mesh. Therefore, when the bending structure generates bending force on the welded wire mesh, the bending of the welded wire mesh can be completed jointly by the bending structure and the movable plate 16, ensuring uniform force distribution during bending and avoiding affecting the bending effect, thereby improving work efficiency. At the same time, a second rubber layer 11 is provided on the surface of each fixed block 13, which increases the friction between the fixed block 13 and the welded wire mesh, thereby better limiting the position of the welded wire mesh.

[0035] When the device is used, the fixed blocks 13 and the connecting blocks 14 are located in the mesh of the reinforcing welded mesh near the bending part, and the adjacent side of the mesh of the reinforcing welded mesh is in contact with the adjacent side of the corresponding fixed block 13, so that the bottom of the connecting block 14 can limit the reinforcing welded mesh, thereby increasing the stability of the bending of the reinforcing welded mesh. Then, the threaded rod 18 is screwed to push the movable plate 16 to rotate, so as to adjust the included angle between the movable plate 16 and the bending structure. Since the design of the coil spring 17 can make one side of the movable plate 16 always in contact with one end of the threaded rod 18, when the reinforcing welded mesh is bent, the bending structure drives the reinforcing welded mesh to bend until the bent reinforcing welded mesh is in contact with the movable plate 16. The bending of different reinforcing welded meshes can be realized by adjusting the included angle between the movable plate 16 and the bending structure. The bending of the reinforcing welded mesh can be realized by the bending structure and the movable plate 16, so that the reinforcing welded mesh is uniformly stressed when it is bent, and the bending effect is not affected, thereby improving the work efficiency.

[0036] In each movable plate 16, a set of limiting blocks 19 are fixedly connected to the side near the threaded rod 18. Each threaded rod 18 is movably arranged in the corresponding limiting block 19, so that the limiting block 19 limits the movement of the corresponding threaded rod 18, thereby increasing the stability of the movement of the threaded rod 18, facilitating the stable rotation of the movable plate 16, so that the bending structure and the movable plate 16 form different included angles, thereby adapting to the bending requirements of different reinforcing welded meshes. Meanwhile, the end of each threaded rod 18 near the movable plate 16 is designed as a rounded structure, which can reduce the friction between the threaded rod 18 and the movable plate 16, thereby better pushing the movable plate 16 to rotate.

[0037] Further, a plurality of sliding blocks 9 are slidably connected to the top of the operation table 1, and each sliding block 9 is connected to the operation table 1 through a spring 10, so that when the reinforcing welded mesh is bent, the surface of the reinforcing welded mesh is abutted against one side of the sliding block 9, thereby pressing the spring 10, and at this time, because the mesh hole of the reinforcing welded mesh close to the bending position is located on the surface of the fixed block 13, the adjacent side of the reinforcing welded mesh is abutted against the adjacent side of the fixed block 13, so that the included angle of the reinforcing welded mesh coincides with the included angle of the side of the fixed block 13 close to the sliding block 9 and the side of the bending structure, and the sliding block 9, the spring 10, the fixed block 13 and the connecting block 14 are used to limit the reinforcing welded mesh of different sizes, thereby increasing the stability of the reinforcing welded mesh during bending, so that the reinforcing welded mesh can be better bent, and the first rubber layer 12 is arranged on one side of the sliding block 9, which protects the reinforcing welded mesh from being abraded during bending, and a plurality of sliding grooves 8 are arranged on the top of the operation table 1, each sliding groove 8 is slidably connected with a sliding block 9 matched with the sliding groove 8, and the spring 10 is arranged between the sliding groove 8 and the sliding block 9, and each sliding block 9 is arranged in a "T" shape.

[0038] In the embodiment, the scale lines are arranged on the surface of the threaded rod 18, so that the movement distances of the plurality of threaded rods 18 are the same, thereby better bending the reinforcing welded mesh, and the bottom of the movable plate 16 is arranged in a rounded corner structure, so that the bending position of the reinforcing welded mesh can form a circular arc, thereby improving the bending effect of the reinforcing welded mesh.

[0039] Although the embodiments of the utility model have been shown and described, the specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and the person skilled in the art can make modifications, replacements and changes of the embodiments without creative contribution after reading the specification without departing from the principles and purposes of the utility model, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
