Description

Technical Field

[0001] This utility model relates to the field of rebar bending machine technology, specifically a rebar bending machine for subway tunnel segment production. Background Technology

[0002] With the acceleration of urbanization, subway construction is in full swing. As the supporting structure of subway tunnels, the quality and production efficiency of subway segments are crucial. As the key skeleton of the segments, steel bars have high requirements for processing precision and speed. Under the wave of large-scale subway construction, the construction industry urgently needs efficient and precise steel bar processing equipment to meet the increasing segment production tasks and promote the smooth progress of subway projects.

[0003] In the current production process of subway tunnel segments, steel bar bending machines are usually used to bend the steel bars to meet the needs of different situations. These machines are specially designed to bend steel bars into the required shape and angle. The main structure of the steel bar bending machine includes a horizontal working disc that rotates on a vertical axis. During operation, the steel bar is placed on the working disc, and through the cooperation of the central pin and the bending pin, as well as the rotational motion of the disc, the steel bar is bent to the required angle.

[0004] Currently, when bending the steel bars produced for subway tunnel segments, the steel bars need to be placed into a disc in sequence. Then, through the cooperation of the central pin and the bending pin, as well as the rotation of the disc, the steel bars are bent to the required angle.

[0005] Currently, in the use of rebar bending machines, because they can only bend one or two or three rebars at a time, the remaining rebars can only be bent after the bending is completed. This results in a slow bending speed for rebars used in subway tunnel segment production, thus reducing work efficiency. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide a steel bar bending machine for subway tunnel segment production, in order to solve the technical problem that the bending speed of steel bars for subway tunnel segment production is slow and thus reduces work efficiency because it can only bend one or two or three steel bars in sequence, and can only bend the remaining steel bars after the bending is completed.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rebar bending machine for subway tunnel segment production, comprising an operating table, a movable block connected to the top of the operating table via multiple telescopic rods, a fixed block fixedly connected to the top of the operating table, a connecting block cooperating with the fixed block rotatably connected to the bottom of the movable block via a shaft, a first rotating shaft rotatably connected to one end of the fixed block, and second rotating shafts cooperating with the first rotating shaft rotatably connected to both sides of the fixed block, a metal synchronous belt mechanism provided between each second rotating shaft and the first rotating shaft, a plurality of baffles fixedly connected to the surface of each metal synchronous belt mechanism, a motor cooperating with the first rotating shaft installed on the top of the operating table, and the output end of the motor connected to one end of the first rotating shaft, the connecting block having an inclined structure, and the end near the second rotating shaft being set at a lower position.

[0008] By adopting the above technical solution, the steel bar to be bent is placed on top of the fixed block, and then the motor is started to drive the first rotating shaft to rotate. Through the first and second rotating shafts, the metal synchronous belt mechanism can drive the baffles to move. This causes a set of matching baffles to move both ends of the steel bar towards the lower part of the connecting block. Therefore, during the movement, the steel bar is bent between the fixed block and the connecting block, ensuring the accuracy and stability of the steel bar bending, which is convenient for the subsequent production of subway segments. This structure can bend multiple steel bars in sequence without waiting for the previous steel bar to be bent before operating on the next steel bar, which can improve the efficiency of steel bar bending.

[0009] The present invention is further configured such that a connecting member is slidably connected to the top of the connecting block, and a movable plate is hinged to the top of the connecting member; the connecting plate is hinged to the bottom of the movable block, and the connecting plate slides within the movable plate.

[0010] By adopting the above technical solution, the connecting plate can slide within the movable plate, thereby adjusting the position of one end of the connecting block. This allows for changes in the tilt angle of the connecting block, making it easier to bend steel bars of different sizes, thus increasing the flexibility of the device.

[0011] The present invention is further configured such that a set of bolts is threadedly connected to both sides of the movable plate, and one end of the bolt is movably connected to the surface of the connecting plate.

[0012] By adopting the above technical solution, the bolts can be tightened to separate them from the connecting plate, thereby adjusting the position of the connecting plate on the movable plate. Alternatively, by tightening the bolts to compress the connecting plate, the position of the connecting plate can be fixed. This structure facilitates precise adjustment of the position of the connecting plate, thereby enabling adjustment of the tilt angle of the connecting block.

[0013] The present invention is further configured such that a groove is provided on the top of the connecting block, and a slider that fits into the groove is slidably connected in the groove. The slider is fixedly connected to the bottom of the connecting member, and the slider is configured as a "T" shaped structure.

[0014] By adopting the above technical solution, the design of the chute and slider can increase the stability of the connecting parts moving on the connecting block, so that the connecting parts can move along a predetermined trajectory, which facilitates the improvement of the stability of the bending machine.

[0015] The present invention is further configured such that the top of the operating table is provided with a set of slots that fit with the metal synchronous belt mechanism and the baffle.

[0016] By adopting the above technical solution, the metal synchronous belt mechanism and the baffle can move within the slot, thereby avoiding affecting the movement of the baffle.

[0017] The present invention is further configured such that a plurality of rollers are provided on the adjacent side of the fixing block and the connecting block.

[0018] By adopting the above technical solution, the friction between the reinforcing bar and the fixed block and connecting block can be reduced, so that when the metal synchronous belt mechanism drives the baffle to move, the reinforcing bar can be pushed to move, so that the reinforcing bar bends on the adjacent side of the fixed block and connecting block.

[0019] The present invention is further configured such that the end of the fixing block near the second rotating shaft is configured as an inclined surface structure.

[0020] By adopting the above technical solution, a guiding function can be achieved. After the steel bar is bent and transported to the corresponding position, it can slide off the fixed block through the inclined structure, thus avoiding the accumulation of steel bars and affecting the use of the device.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention involves placing the steel bar to be bent on top of a fixed block, then starting a motor to rotate the first shaft, which in turn drives a metal synchronous belt mechanism and baffles. This causes a set of matching baffles to move both ends of the steel bar towards the lower part of the connecting block, thus pushing the steel bar to bend. This facilitates the subsequent production of subway tunnel segments. This structure can bend multiple steel bars sequentially without waiting for the previous steel bar to be bent before operating on the next one, thereby improving the efficiency of steel bar bending.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] Although a steel bar bending machine for subway segment production has been shown and described according to this utility model, such as Figure 1-5 As shown, the system includes an operating platform 1. The top of the operating platform 1 is connected to a movable block 3 via multiple telescopic rods 2. The distance between the operating platform 1 and the movable block 3 can be adjusted by the telescopic rods 2. Therefore, in the production of subway tunnel segments, it can adapt to the bending requirements of steel bars of different specifications.

[0032] Subsequently, a fixed block 4 is fixedly connected to the top of the operating platform 1. The bottom of the movable block 3 is rotatably connected to a connecting block 5 that cooperates with the fixed block 4 via a shaft. The bending of the steel bar can be completed by the cooperation of the fixed block 4 and the connecting block 5. A first rotating shaft 6 is rotatably connected to one end of the fixed block 4, and a second rotating shaft 7 that matches the first rotating shaft 6 is rotatably connected to both sides of the fixed block 4. A metal synchronous belt mechanism 8 is provided between each second rotating shaft 7 and the corresponding first rotating shaft 6. Several baffles 9 are fixedly connected to the surface of each metal synchronous belt mechanism 8, and the baffles 9 do not affect the rotation of the metal synchronous belt mechanism 8. A motor 10 that matches the first rotating shaft 6 is installed on the top of the operating platform 1, and the output end of the motor 10 is connected to... Connected to one end of the first rotating shaft 6, the first rotating shaft 6 can be driven to move by the motor 10. Thus, the first rotating shaft 6, the second rotating shaft 7, and the metal synchronous belt mechanism 8 can move, thereby pushing the reinforcing bar. The connecting block 5 has an inclined structure, and the end near the second rotating shaft 7 is set to a lower position. Therefore, when the reinforcing bar enters between the fixed block 4 and the connecting block 5, the metal synchronous belt mechanism 8 can drive the baffle 9 to move. The baffle 9 pushes the reinforcing bar from the height of the connecting block 5 to the lower position, so that the reinforcing bar can be bent. This structure can bend multiple reinforcing bars in sequence without waiting for the previous reinforcing bar to be bent before operating the next reinforcing bar, which can improve the working efficiency of reinforcing bar bending.

[0033] The top of the operating platform 1 is provided with a set of slots 11 that fit with the metal synchronous belt mechanism 8 and the baffle 9, so that the metal synchronous belt mechanism 8 and the baffle 9 can move within the slots 11. This can prevent the operating platform 1 from affecting their movement and thus affecting the use of the bending machine. In addition, several rollers 12 are provided on the adjacent side of the fixing block 4 and the connecting block 5, which can reduce the friction between the steel bar and the fixing block 4 and the connecting block 5, so as to avoid the bending of the steel bar due to excessive friction when bending the steel bar, and also to avoid friction on the surface of the steel bar, thus affecting its use.

[0034] A connector 18 is slidably connected to the top of the connecting block 5, and a movable plate 15 is hinged to the top of the connector 18. A connecting plate 16 is hinged to the bottom of the movable block 3, and the connecting plate 16 slides within the movable plate 15. By adjusting the position of the connecting plate 16 within the movable plate 15, the position of one end of the connecting block 5 can be adjusted, thus changing the tilt angle of the connecting block 5. This allows it to bend steel bars of different sizes, increasing the flexibility of the device. A set of bolts 17 is threaded to both sides of the movable plate 15, and one end of the bolts 17 is movably connected to the connecting plate. The design of bolt 17 on the surface of connecting plate 16 allows for fixing the position of connecting plate 16. Therefore, when bolt 17 is tightened to separate it from connecting plate 16, connecting plate 16 can slide within movable plate 15, thereby adjusting the tilt angle of connecting block 5. When bolt 17 is tightened to press connecting plate 16, the position of connecting plate 16 within movable plate 15 can be fixed, thereby fixing the tilt angle of connecting block 5. This helps users to accurately adjust the position of connecting plate 16, so that the tilt angle of connecting block 5 meets the bending requirements of steel bars in subway tunnel segment production.

[0035] Meanwhile, a groove 13 is provided on the top of the connecting block 5. A slider 14 that matches the groove 13 is slidably connected in the groove 13. The slider 14 is fixedly connected to the bottom of the connecting member 18, so that the connecting member 18 moves along a predetermined trajectory through the groove 13 and the slider 14. The slider 14 is set as a "T" shaped structure, which can increase the stability of the movement of the slider 14 and the connecting member 18, thereby increasing the stability of the rebar bending machine.

[0036] In this embodiment, the end of the fixing block 4 near the second rotating shaft 7 is set as an inclined structure. Therefore, when the baffle 9 pushes the steel bar to move and completes the bending of the steel bar, the steel bar can be guided by the inclined structure to the end of the fixing block 4 near the second rotating shaft 7, so that the bent steel bar can be discharged from the top of the fixing block 4, avoiding affecting the bending of subsequent steel bars and helping to improve work efficiency.
