Description

Technical Field

[0001] This utility model relates to the technical field of rebar bending workbench, and in particular to a dual-station alternating rebar continuous bending workbench. Background Technology

[0002] In the construction industry, steel bar processing is an indispensable and crucial step, with the steel bar bending process having a decisive impact on the shape and mechanical properties of structural components. Traditional steel bar bending workbenches are mostly single-station designs, typically equipped with a fixed bending end. During operation, the steel bar needs to be repeatedly positioned and bent at this single station. After years of development, this type of workbench has, to a certain extent, met routine production needs and has been widely used in small-scale construction projects and in scenarios where the requirements for steel bar bending accuracy and efficiency are not high.

[0003] However, with the continuous development of the construction industry and the increasing complexity of engineering projects, the limitations of traditional single-station rebar bending workbenches have gradually become apparent. Their single-station operation mode leads to low production efficiency, making it difficult to meet construction schedule requirements when faced with large-scale, high-strength rebar processing tasks. Furthermore, during operation, workers need to frequently perform repetitive operations in the same position, resulting in high labor intensity and a high risk of safety accidents due to operator fatigue. Utility Model Content

[0004] In view of this, the embodiments of this utility model provide a dual-station alternating continuous bending workbench for reinforcing bars, which solves the problem that existing reinforcing bar bending mostly adopts single-station bending, which cannot prevent mistakes and is inefficient.

[0005] An embodiment of this utility model provides a dual-station alternating rebar continuous bending workbench, comprising: A workbench includes a table surface and two workstations, the two workstations being symmetrically arranged on the table surface, and each workstation being provided with two pressure columns. A bending structure includes a support rod, a first rotating sleeve and a second rotating sleeve. The first rotating sleeve and the second rotating sleeve are continuously sleeved on the outside of the support rod and can rotate around the support rod in a circular trajectory. The first rotating sleeve is provided with a first bending head, and the second rotating sleeve is provided with a second bending head that is on the same circular trajectory as the first bending head. The drive structure, located below the platform, includes a gear frame, a first gear, a second gear, and a drive component. The movable end of the drive component is connected to the gear frame. The first gear is connected to the first rotating sleeve, and the second gear is connected to the second rotating sleeve. The gear frame meshes with both the first gear and the second gear. The meshing portions of the gear frame, the first gear, and the second gear are symmetrical about the support rod, causing the first gear and the second gear to rotate in opposite directions driven by the gear frame. This controls the first bending head and the second bending head to approach and continuously bend at the two workstations.

[0006] Furthermore, the upper end of the first rotating sleeve is provided with a first extension, and the first bending head is disposed on the first extension; The upper end of the second rotating sleeve is provided with a second extension, and the second bending head is provided on the second extension, and the second bending head and the first bending head are at the same height.

[0007] Furthermore, the height of the second rotating sleeve is lower than that of the first rotating sleeve, and an elevation platform is provided at the end of the second extension. The second bending head is disposed on the elevation platform so that the height of the second bending head and the first bending head are flush.

[0008] Furthermore, the toothed frame includes a rectangular frame, a first toothed rack and a second toothed rack disposed inside the rectangular frame, the first toothed rack and the second toothed rack having different heights; The first rack meshes with the first gear teeth, and the second rack meshes with the second gear teeth.

[0009] Furthermore, the bottom of the tabletop is provided with two slide rails, and the rectangular frame is slidably disposed between the two slide rails.

[0010] Furthermore, the driving component is a hydraulic cylinder, and the direction of movement of the driving component is consistent with the length direction of the slide rail.

[0011] Furthermore, a base is provided at the bottom of the tabletop, and the support rod is disposed on the base.

[0012] Furthermore, a pad is provided on the outer wall of the support rod, and the pad is located between the first gear and the second gear.

[0013] Furthermore, the support rod extends to the same height on the platform as the pressure column.

[0014] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The dual-station alternating continuous rebar bending workbench of this utility model, by setting up dual stations and cooperating with the alternating approach and bending of the first bending head and the second bending head on both sides, can realize the continuous processing of rebar, which greatly improves the efficiency of rebar bending work. Compared with the traditional single-station workbench, it can meet the needs of larger-scale and higher-strength rebar processing tasks, effectively shorten the construction cycle, and reduce labor costs. Secondly, in terms of processing quality, the flush design of the bending head and the stable structural connection ensure the uniformity of the stress on the rebar during the bending process, improve the bending accuracy and quality, and the processed rebar components have better dimensional consistency, which better meets the accuracy requirements of the construction and other fields, and reduces rework and material waste caused by dimensional deviations.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please refer to Figures 1 to 2 The present invention provides a dual-station alternating continuous bending workbench for reinforcing bars, including a workbench, a bending structure and a driving structure.

[0024] The workbench consists of a tabletop 1 and two workstations 2, which are symmetrically arranged on the tabletop 1. The tabletop 1 can be made of high-strength steel to ensure the stability of the overall structure. Each workstation 2 is equipped with two pressure columns 3, which can be fixed to the workstation 2 by means of bolts or other methods to ensure stable positioning and support of the steel bars during bending, preventing displacement of the steel bars during bending.

[0025] The workbench surface 1 is equipped with a base 4 at the bottom. The base 4 and the workbench surface 1 can be connected by welding or bolts to make the entire workbench structure more stable and provide a solid foundation for bending operations.

[0026] Please refer to Figure 3In this embodiment, the bending structure includes a support rod 5, a first rotating sleeve 6, and a second rotating sleeve 7. The support rod 5 is mounted on the base 4 and can be connected to the base 4 by means of bolt fastening or welding to ensure the stability of the support rod 5. The first rotating sleeve 6 and the second rotating sleeve 7 are continuously sleeved on the outside of the support rod 5 and can rotate around the support rod 5 in a circular trajectory.

[0027] Specifically, the inner diameter of the first rotating sleeve 6 corresponds to that of the support rod 5, and the first rotating sleeve 6 is rotatably mounted on the outside of the support rod 5. The inner diameter of the second rotating sleeve 7 corresponds to that of the first rotating sleeve 6, and the second rotating sleeve 7 is rotatably mounted on the outside of the first rotating sleeve 6, so that the first rotating sleeve 6 and the second rotating sleeve 7 are coaxially arranged.

[0028] It is understandable that the connection between the first rotating sleeve 6 and the second rotating sleeve 7 can also be achieved by setting corresponding bearings or rotating pairs on the support rod 5, so that the first rotating sleeve 6 and the second rotating sleeve 7 can rotate flexibly.

[0029] Furthermore, the first rotating sleeve 6 is provided with a first bending head 9, and a first extension 8 is provided at its upper end. The first bending head 9 is installed on the first extension 8 and can be fixed by bolt connection or welding.

[0030] The second rotating sleeve 7 is provided with a second bending head 12. Similarly, the upper end of the second rotating sleeve 7 has a second extension 10, and the second bending head 12 is installed on the second extension 10.

[0031] In order to make the second bending head 12 and the first bending head 9 have the same height, since the height of the second rotating sleeve 7 is lower than that of the first rotating sleeve 6, a raising platform 11 is provided at the end of the second extension 10, and the second bending head 12 is fixedly installed on the raising platform 11.

[0032] In another alternative embodiment, such as Figure 4 As shown, a pad 14 is provided on the outer wall of the support rod 5, and the pad 14 is located between the first gear 13 and the second gear 15.

[0033] The pad 14 can be tightly connected to the support rod 5 by bolts, which serves to support and position the first gear 13 and the second gear 15, and also helps to maintain the stability of the entire bending structure.

[0034] Please refer to Figure 3 The drive structure is located below the platform 1 and includes a gear frame, a first gear 13, a second gear 15 and a drive component. The drive component is a hydraulic cylinder 20, whose direction of movement is consistent with the length direction of the slide rail 16. The movable end of the hydraulic cylinder 20 is connected to the gear frame and can be reliably connected through a connecting rod to ensure that the gear frame can be smoothly driven when the hydraulic cylinder 20 is working.

[0035] Furthermore, the toothed frame is composed of a rectangular frame 17, a first toothed rack 18 and a second toothed rack 19 disposed inside the rectangular frame 17, and the first toothed rack 18 and the second toothed rack 19 are at different heights inside the rectangular frame 17.

[0036] The first rack 18 meshes with the first gear 13, and the second rack 19 meshes with the second gear 15. Two slide rails 16 are provided at the bottom of the platform 1, and the rectangular frame 17 is slidably disposed between the two slide rails 16. This sliding connection can be achieved by setting a slider on the slide rail 16 and fixing the rectangular frame 17 to the slider, so that the rack and frame can slide smoothly on the slide rail 16.

[0037] It should be further explained that the first gear 13 is connected to the first rotating sleeve 6 by means of key connection or other methods, so that the first gear 13 can drive the first rotating sleeve 6 to rotate synchronously; similarly, the second gear 15 is connected to the second rotating sleeve 7 by means of key connection or other appropriate methods, so as to ensure that the second gear 15 drives the second rotating sleeve 7 to rotate.

[0038] It is worth noting that the gear frame is simultaneously engaged with the first gear 13 and the second gear 15, and the meshing parts of the gear frame, the first gear 13, and the second gear 15 are symmetrical about the support rod 5. Thus, when the drive unit drives the gear frame to move, the first gear 13 and the second gear 15 are driven by the gear frame in opposite directions, thereby controlling the first bending head 9 and the second bending head 12 to approach each other at the two workstations 2, thereby realizing continuous bending operation.

[0039] The support rod 5 extends to the same height as the pressure column 3 on the worktable 1. This design helps to ensure the height coordination of all components on the worktable 1, facilitates the placement and bending of steel bars, and also helps to maintain the stability of the center of gravity of the entire equipment, improving the reliability and safety during operation.

[0040] The working principle of the above embodiments is as follows: When the hydraulic cylinder 20 drives the gear frame components, namely the rectangular frame 17, the first rack 18, and the second rack 19, to move along the slide rail 16, the first rack 18 and the second rack 19 mesh with the first gear 13 and the second gear 15, respectively. Since the movement direction and position of the gear frame components are symmetrical to the support rod 5, the first gear 13 and the second gear 15 are driven in opposite directions. This causes the first rotating sleeve 6 and the second rotating sleeve 7 to rotate around the support rod 5 in opposite directions. At this time, the first bending head 9 and the second bending head 12 are driven and move closer to each other at one station 2 to bend the steel bar. The rectangular frame 17 is then controlled to move in the opposite direction, so that the first bending head 9 and the second bending head 12 move closer to each other at another station 2 to bend the steel bar. Through this alternating rotation, the steel bars at the two stations 2 can be continuously bent on both sides, thereby achieving efficient and precise steel bar processing.

[0041] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0042] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0043] 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, 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.
