Description

Technical Field

[0001] This utility model belongs to the field of highway engineering technology, and in particular relates to a steel bar bending device for highway engineering. Background Technology

[0002] Reinforcing bars have high strength and rigidity, and there are many diameters and types of reinforcing bars depending on the application. Generally, reinforcing bars used in highway engineering need to be bent. In highway construction, bending of reinforcing bars is an important operation, and its quality and efficiency directly affect the overall progress and quality of the project. Because of the high strength of the reinforcing bars themselves, bending is carried out with the help of equipment.

[0003] For example, Chinese Patent (Publication No.: CN218080135U) discloses a steel bar bending device for highway engineering, belonging to the field of highway engineering assembly technology. It includes a workbench, on which a turntable is rotatably mounted. A motor is provided at the bottom of the workbench, and a reduction assembly connected to the top of the motor is connected to the workbench. The motor drives the turntable to rotate at a reduced speed through the reduction assembly. A rotating central shaft is coaxially fixed on the surface of the turntable. A first sliding groove is opened on the surface of the turntable, and a first threaded rod is rotatably mounted in the first sliding groove. A limit shaft is threadedly connected to the first threaded rod. Multiple fixed seats are fixedly provided at one end of the surface of the workbench. A first fixed rotating shaft is installed on one side of the surface of the fixed seat, and a second fixed rotating shaft is connected to the other side of the surface of the fixed seat. This application uses first and second fixed rotating shafts to fix the reinforcing bars during use, preventing them from shifting during bending. However, in practice, the reinforcing bars can only be bent in a two-dimensional plane. When the reinforcing bars need to be bent multiple times to form a three-dimensional shape, it is difficult to use, and the reinforcing bars are prone to rotation during bending, which affects the angle of the second bend, leading to the scrapping of the reinforcing bars, causing certain economic losses, and greatly affecting the practicality of the equipment. Therefore, a reinforcing bar bending device for highway engineering is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a steel bar bending device for highway engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A steel bar bending device for highway engineering includes a workbench, an adjustment assembly connected to the top of the workbench, a displacement sensor connected inside the adjustment assembly, a connecting plate slidably connected to the top of the workbench, a fixing assembly connected to the top of one side of the connecting plate, a limit plate welded to the top of the other side of the connecting plate, and a movable plate welded to one side of the limit plate. The adjustment assembly includes a second motor, the output end of which is connected to a first lead screw. A movable plate is threadedly connected to the outer side of the first lead screw. A spring is embedded inside the movable plate. One end of the spring is connected to a movable block. A sliding groove is provided on one side of the movable plate. A limit rod is connected through the top side of the movable plate.

[0006] In a further technical solution, the number of fixing components is three. Each fixing component includes a knob, a second lead screw welded to one side of the knob, a movable block connected to the outer side of the second lead screw by a thread, a fixed shaft connected to the top of the movable block, a support plate connected to the bottom of the worktable, a first motor connected to the top of the support plate, a turntable connected to the output end of the first motor, one of the fixing components connected to the top of the turntable, and the other two fixing components connected to the top of the connecting plate and one side of the movable plate, respectively.

[0007] A further technical solution is provided, wherein a rotating central shaft is connected through the middle of the turntable, a limiting shaft is welded to the top of the connecting plate and one side of the movable plate, and rubber sleeves are fitted on the outer sides of the fixed shaft, the rotating central shaft and the limiting shaft, and the movable block has a convex design.

[0008] In a further technical solution, the spring is connected to one end of the slide groove, the moving block is located inside the slide groove, the moving block has a convex design, and there are two slide grooves, two moving blocks, and two springs.

[0009] In a further technical solution, the other side of the movable plate is connected to one side of the moving plate, and one side of both the limiting plate and the connecting plate are welded to the moving plate.

[0010] In a further technical solution, the displacement sensor is located on one side of the moving plate, and a protective box is connected to the outside of the second motor, with one side of the protective box connected to one side of the workbench.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a fixing component on top of the turntable and connecting plate to fix the reinforcing bar laterally. A movable plate and its side fixing component fix the bent portion of the reinforcing bar after the first bend. By starting the first motor to rotate the turntable, the reinforcing bar is bent a second time to form a three-dimensional reinforcing bar frame, greatly improving the equipment's practicality. During use, the springs and moving blocks allow users to easily adjust the equipment based on the length of the first bend, further enhancing its applicability. The three fixing components prevent the reinforcing bar from rotating during bending, thus avoiding any impact on the bending angle. This invention features an embedded displacement sensor within the adjustment component, enabling real-time monitoring of the displacement of the moving plate. This allows for precise control of the rebar's position adjustment accuracy during bending. Compared to relying on manual adjustment of the bending position using graduated strips, this design effectively avoids human error and ensures that the rebar bending length parameters meet the requirements of highway engineering construction specifications. It is particularly suitable for rebar processing in critical areas such as roadbed reinforcement and bridge bearings where high precision is required, providing a reliable guarantee for the stability of engineering structures.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] like Figures 1-4As shown, this utility model embodiment provides a steel bar bending device for highway engineering, including a workbench 1, an adjustment component 2 connected to the top of the workbench 1, a displacement sensor 3 connected inside the adjustment component 2, a connecting plate 4 slidably connected to the top of the workbench 1, a fixing component 5 connected to the top of one side of the connecting plate 4, a limiting plate 6 welded to the top of the other side of the connecting plate 4, and a movable plate 7 welded to one side of the limiting plate 6. The adjustment assembly 2 includes a second motor 201, the output end of which is connected to a first lead screw 202. A movable plate 203 is threadedly connected to the outside of the first lead screw 202. A spring 204 is embedded inside the movable plate 203. One end of the spring 204 is connected to a movable block 205. A groove 206 is provided on one side of the movable plate 203. A limit rod 207 is connected through the top side of the movable plate 203.

[0018] In this embodiment, by activating the second motor 201, the first lead screw 202 can be rotated, thereby causing the moving plate 203, which is threadedly connected to the second lead screw 202, to move. The displacement sensor 3 is connected to the second motor 201 via a controller. When the moving plate 203 moves to the preset position of the displacement sensor 3, the controller can stop the second motor 201, thus facilitating the user to adjust the bending position of the reinforcing bar and reducing errors from manual adjustment. Rotating the knob 501 can drive the second lead screw 502 to rotate, thereby moving the moving plate 203, which is threadedly connected to the second lead screw 202. The rod 502 moves via the threaded movable block 503, and can then fix the reinforcing bar via the fixed shaft 504, the rotating central shaft 11, and the limiting shaft 12. When the reinforcing bar needs to be bent a second time, simply place the section of the reinforcing bar to be bent on the turntable 10 and the connecting plate 4, fix it with the corresponding fixing component 5, and then adjust the position of the movable plate 7 via the moving block 205 and the spring 204. Fix the other section of the reinforcing bar with the fixing component 5 on one side of the movable plate 7 to prevent the reinforcing bar from rotating during the second bend, which would affect the bending angle of the reinforcing bar.

[0019] like Figure 2 , Figure 3 and Figure 4 As shown, specifically, there are three fixing components 5. The fixing components 5 include a knob 501, a second lead screw 502 welded to one side of the knob 501, a movable block 503 connected to the outside of the second lead screw 502 by a thread, a fixed shaft 504 connected to the top of the movable block 503, a support plate 8 connected to the bottom of the worktable 1, a first motor 9 connected to the top of the support plate 8, and a turntable 10 connected to the output end of the first motor 9. One fixing component 5 is connected to the top of the turntable 10, and the other two fixing components 5 are connected to the top of the connecting plate 4 and one side of the movable plate 7, respectively. A rotating central shaft 11 is connected through the middle of the turntable 10. A limiting shaft 12 is welded to the top of the connecting plate 4 and one side of the movable plate 7. Rubber sleeves 13 are fitted on the outside of the fixed shaft 504, the rotating central shaft 11 and the limiting shaft 12. The movable block 503 has a convex design. Spring 204 is connected to one end of slide 206, and moving block 205 is located inside slide 206. Moving block 205 has a convex design. There are two slides 206, two moving blocks 205 and two springs 204. The other side of the movable plate 7 is connected to one side of the movable plate 203, and one side of the limiting plate 6 and the connecting plate 4 are both welded to the movable plate 203. The displacement sensor 3 is located on one side of the moving plate 203. The outer side of the second motor 201 is connected to the protective box 14, and one side of the protective box 14 is connected to one side of the workbench 1.

[0020] In this embodiment, after the reinforcing bars are fixed, the first motor 9 can be started to drive the turntable 10 to rotate and bend the reinforcing bars. Rubber sleeves 13 are all fitted on the outside of the fixed shaft 504, the rotating central shaft 11, and the limiting shaft 12. On the one hand, this enhances the friction on the reinforcing bars and prevents them from sliding and shifting during bending. On the other hand, it avoids surface damage caused by direct contact between the reinforcing bars and metal parts, ensuring the mechanical properties of the reinforcing bars and effectively improving the bending quality and consistency. At the same time, the convex design of the moving block 205 and the slide 206, as well as the setting of the limiting rod 207, ensures that the movement process is stable and smooth. In addition, the device can adapt to the processing needs of reinforcing bars of different diameters and lengths by adjusting the spacing of the fixed components 5 and the position of the moving plate 203. There is no need to equip special equipment for reinforcing bars of different specifications, reducing equipment investment costs and construction site occupation, and improving construction efficiency.

[0021] The working principle of this utility model is as follows: First, the reinforcing bar is placed on the turntable 10 and the connecting plate 4, ensuring that one end of the reinforcing bar is connected to the limiting plate 6. Then, by starting the second motor 201, the first lead screw 202 can be driven to rotate, thereby driving the moving plate 203, which is threadedly connected to the second lead screw 202, to move. The displacement sensor 3 is connected to the second motor 201 through a controller. When the moving plate 203 moves to the preset position of the displacement sensor 3, the controller can stop the second motor 201, thus facilitating the user to adjust the bending position of the reinforcing bar. Finally, rotating the knob 501 can drive the second lead screw 502. The rotation causes the movable block 503, which is threadedly connected to the second lead screw 502, to move. The reinforcing bar can then be fixed by the fixed shaft 504, the rotating central shaft 11, and the limiting shaft 12. When the reinforcing bar needs to be bent a second time, simply place the section of the reinforcing bar to be bent on the turntable 10 and the connecting plate 4, fix it with the corresponding fixing component 5, adjust the position of the movable plate 7 with the moving block 205 and the spring 204, and fix the other section of the reinforcing bar with the fixing component 5 on one side of the movable plate 7. After the reinforcing bar is fixed, the first motor 9 can be started to drive the turntable 10 to rotate and bend the reinforcing bar.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
