Description

Technical Field

[0001] This utility model relates to the field of steel bar bending machine technology, and in particular to a steel bar bending machine for truss bars. Background Technology

[0002] In modern architecture, especially in concrete structures, truss reinforcement plays a crucial role. It enhances the load-bearing capacity and shear resistance of concrete slabs, effectively controlling crack development during use. For example, truss reinforcement is increasingly used in the floor slabs of high-rise buildings, basement roof slabs, and roof structures of some large industrial buildings because it improves the overall integrity and stability of the structure, ensuring the building's safety performance.

[0003] During truss construction, steel bars are needed for connection, which requires bending machines to bend the steel bars. However, traditional bending machines are inconvenient to operate on trusses, and they are also not easy to adjust for bending steel bars of different sizes. Therefore, this utility model proposes a steel bar bending machine for truss bars to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steel bar bending machine for truss reinforcement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steel bar bending machine for truss reinforcement includes a fixed plate, a fixed rod fixedly connected to the upper end of the fixed plate, a fixed mold fixedly sleeved on the fixed rod, a rotating plate rotatably sleeved on the fixed rod, a through groove on the rotating plate, a slider slidably connected in the through groove, a mating mold cooperating with the fixed mold rotatably connected to the lower end of the slider, a moving mechanism for moving the mating mold provided in the through groove, a sliding groove provided at the lower end of the fixed plate, a fixing mechanism for fixing the fixed plate provided in the sliding groove, the fixing mechanism including two symmetrically arranged clamping plates slidably connected in the sliding groove, a double-ended threaded rod rotatably connected between the inner walls of the two ends of the sliding groove, the double-ended threaded rod passing through the two clamping plates and threadedly connected to them.

[0007] Preferably, the moving mechanism includes a screw rotatably connected between the inner walls of both ends of the through groove, the screw passing through the slider and threadedly connected thereto, and a rotating block fixedly sleeved on the screw.

[0008] Preferably, one end of the double-ended threaded rod passes through the side wall of the fixed plate and is rotatably connected to it, and a turntable is fixedly sleeved at the end of the double-ended threaded rod.

[0009] Preferably, two limiting blocks are fixedly connected to the upper end of the fixing plate.

[0010] Preferably, a handle is fixedly connected to the end of the rotating plate away from the fixed rod, and a telescopic rod is slidably connected inside the handle.

[0011] Preferably, the telescopic rod has a groove on its side wall, a positioning block is slidably connected in the groove, the handle has a plurality of equally spaced positioning holes, the positioning block cooperates with the positioning holes, and the lower end of the positioning block is elastically connected to the inner wall of the groove by a spring.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting a fixing mechanism, when used on a truss, the turntable can be rotated, thereby driving the double-headed threaded rod to rotate, which in turn drives the two clamps connected to it to move towards the middle. The clamps hold the truss, thereby fixing the fixing plate and bending device, making it easy to use on the truss and greatly improving the convenience of the device.

[0014] 2. By setting up a moving mechanism, when it is necessary to bend steel bars of different diameters, rotating the rotating block drives the screw to rotate, thereby driving the slider connected to it to move. The movement of the slider drives the mating mold to move. By adjusting the distance between the fixed mold and the mating mold, it is possible to bend steel bars of different diameters, which can greatly improve the practicality of the device.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Reference Figure 1-5 A steel bar bending machine for truss reinforcement includes a fixed plate 1, a fixed rod 8 fixedly connected to the upper end of the fixed plate 1, a fixed mold 2 fixedly sleeved on the fixed rod 8, a rotating plate 9 rotatably sleeved on the fixed rod 8, a through groove 13 opened on the rotating plate 9, a slider 12 slidably connected in the through groove 13, a matching mold that cooperates with the fixed mold 2 rotatably connected to the lower end of the slider 12, and two limiting blocks 5 fixedly connected to the upper end of the fixed plate 1. When in use, the steel bar is placed between the two limiting blocks 5 to limit the steel bar and prevent it from rotating during bending.

[0023] The through groove 13 is provided with a moving mechanism for moving the mating mold. The moving mechanism includes a screw 11 rotatably connected between the inner walls of the two ends of the through groove 13. The screw 11 passes through the slider 12 and is threadedly connected to it. A rotating block 10 is fixedly sleeved on the screw 11. Both the screw 11 and the double-ended threaded rod 7 have a self-locking function.

[0024] The lower end of the fixed plate 1 is provided with a sliding groove 6. A fixing mechanism for fixing the fixed plate 1 is provided in the sliding groove 6. The fixing mechanism includes two symmetrically arranged clamping plates 4 that are slidably connected in the sliding groove 6. A double-threaded rod 7 is rotatably connected between the inner walls of both ends of the sliding groove 6. The double-threaded rod 7 passes through the two clamping plates 4 and is threadedly connected to them. One end of the double-threaded rod 7 passes through the side wall of the fixed plate 1 and is rotatably connected to it. A turntable 3 is fixedly sleeved on the end of the double-threaded rod 7. The threads at both ends of the double-threaded rod 7 are in opposite directions.

[0025] A handle 14 is fixedly connected to the end of the rotating plate 9 away from the fixed rod 8. A telescopic rod 15 is slidably connected inside the handle 14. A groove 17 is provided on the side wall of the telescopic rod 15. A positioning block 16 is slidably connected inside the groove 17. A plurality of positioning holes 19 are provided on the handle 14 at equal intervals. The positioning block 16 cooperates with the positioning holes 19. The lower end of the positioning block 16 is elastically connected to the inner wall of the groove 17 by a spring 18. The telescopic length of the telescopic rod 15 can be adjusted by the positioning block 16 and the positioning holes 19. When extended, it is easy to bend. When retracted, it can reduce the space occupied and facilitate storage.

[0026] When this utility model is used on a truss, the turntable 3 can be rotated, thereby driving the double-headed threaded rod 7 to rotate, which in turn drives the two clamping plates 4 connected to it to move towards the center. The clamping plates 4 are used to clamp the truss, thereby fixing the fixed plate 1 and the bending device, which is convenient for use on the truss. When bending, the steel bar is placed between the fixed mold 2 and the mating mold. The telescopic rod 15 is rotated to drive the rotating plate 9 to rotate, which in turn drives the mating mold to rotate, bending the steel bar. When it is necessary to bend steel bars of different diameters, the rotating block 10 is rotated, which drives the screw 11 to rotate, thereby driving the slider 12 connected to it to move. The movement of the slider 12 drives the mating mold to move. Adjusting the distance between the fixed mold 2 and the mating mold can enable bending of steel bars of different diameters. When bending, the positioning block 16 is pressed, and the telescopic rod 15 is pulled outward, so that the positioning block 16 enters the positioning hole 19 away from the rotating plate 9, thereby positioning the telescopic rod 15. Adjusting the length of the telescopic rod 15 can make bending easier.
