Technical Field
[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a reinforcing bar bending device for construction engineering. Background Technique
[0002] Reinforcing bars refer to steel bars used in reinforced concrete and prestressed reinforced concrete. Their cross-section is circular and sometimes square with rounded corners. It includes plain round bars, ribbed bars, and twisted bars. The steel bars for reinforced concrete are straight or coiled steel bars used for the reinforcement of reinforced concrete. Their shapes are divided into plain round bars and deformed bars. The delivery states are straight bars and coiled rounds. Plain round bars are actually small round bars and coiled rounds of ordinary low-carbon steel. Deformed bars are ribbed bars on the surface, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length direction. The shape of the transverse ribs is one of spiral, herringbone, and crescent. It is expressed in millimeters of the nominal diameter. The nominal diameter of the deformed bar is equivalent to the nominal diameter of the plain round bar with the same cross-sectional area. The nominal diameter of the reinforcing bar is 8 - 50 millimeters, and the recommended diameters are 8, 12, 16, 20, 25, 32, and 40 millimeters. Steel grades: 20MnSi, 20MnV, 25MnSi, BS20MnSi. Reinforcing bars mainly bear tensile stress in concrete. Due to the effect of the ribs, deformed bars have a greater bonding ability with concrete, so they can better bear the external force. Reinforcing bars are widely used in various building structures, especially large, heavy, light thin-walled, and high-rise building structures.
[0003] In the utility model patent with the publication number CN 214720093 U, a reinforcing bar bending device for construction engineering is proposed, belonging to the technical field of construction engineering equipment. A reinforcing bar bending device for construction engineering includes an operating table. A clamping mechanism is installed at the upper end of the operating table. A first fixing plate is fixedly connected to the upper end of the operating table. The clamping mechanism is located directly in front of the first fixing plate. A threaded rod is threadedly connected to the end of the first fixing plate away from the clamping mechanism. The threaded rod passes through the first fixing plate and extends to the front side of the first fixing plate. A clamping plate is arranged on the side of the threaded rod close to the clamping mechanism. A support frame is fixedly connected to the upper end of the operating table. The support frame is located directly to the right of the first fixing plate. An electric telescopic rod is installed inside the support frame. The lower end of the electric telescopic rod is fixedly connected to a moving block. A toothed plate is arranged at the upper end of the moving block. A through groove is opened at the outer end of the toothed plate. It can achieve more stable clamping of the reinforcing bar, avoid the offset of the reinforcing bar during the bending process, and reduce the processing error of the reinforcing bar.

Detailed implementation manners
[0029] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following further detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings of the specification.
[0030] In the following description, many specific details are set forth in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0031] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. The present utility model provides the following embodiments.
[0032] A steel bar bending device for construction engineering proposed by the present utility model, such as Figure 1 , Figure 2 and Figure 3As shown in the figure, it includes two horizontally movable moving plates 7, a fixed table 1 and a mounting structure 20. One end of the fixed table 1 is fixedly installed with a driving motor 5. A driving screw rod 6 is fixedly connected to the output shaft of the driving motor 5. A groove is formed inside the fixed table 1. The driving screw rod 6 is located inside the groove. The two moving plates 7 are symmetrically threadedly connected to the outside of the driving screw rod 6. When the driving motor 5 is started, the two moving plates 7 can move linearly on the outside of the driving screw rod 6. A convex block is arranged outside the fixed table 1. A hydraulic rod 2 is fixedly installed inside the convex block. The telescopic end of the hydraulic rod 2 is fixedly connected to a top plate 3, which can drive the top plate 3 to move in the vertical direction. A bending roller 4 and a limiting roller 8 are fixedly installed on the outside of the top plate 3 and the tops of the fronts of the two moving plates 7 respectively through the mounting structure 20. The vertical movement of the bending roller 4 can cooperate with the limiting roller 8 to realize the bending of the steel bar.
[0033] As Figure 2 , Figure 3 and Figure 5 shown, the mounting structure 20 includes a first docking shaft 21, a second docking shaft 22, a limiting rod 9, an elastic member 10, a movable plate 11, a pressing block 12 and a limiting block 13. The first docking shaft 21 is rotatably connected to the moving plate 7 or the top plate 3; a roller is rotatably connected to the outside of the second docking shaft 22. A cavity is formed at the docking part of the first docking shaft 21. Limiting grooves are formed at the top and bottom of the cavity. A cavity is also formed at the docking part of the second docking shaft 22. Two limiting rods 9 are fixedly connected inside the cavity. Two movable plates 11 are symmetrically slidably connected to the outside of the two limiting rods 9. Pressing blocks 12 and limiting blocks 13 are fixedly connected to the outside of the top movable plate 11 and the bottom movable plate 11. The opposite surfaces of the top movable plate 11 and the bottom movable plate 11 are fixedly connected through the elastic member 10. The outside of the limiting block 13 is adapted to the inside of the limiting groove. After the first docking shaft 21 and the second docking shaft 22 are docked, one end of the movable plate 11 extends into the first docking shaft 21, and the limiting block 13 is embedded into the limiting groove and is in close fit with the limiting groove. After the fit, the installation of the roller can be realized. The elastic member 10 can be a spring. The number of springs is two. The two springs are respectively sleeved on the outside of the two limiting rods 9. When the two movable plates 11 approach, the springs are compressed. When the pressure applied to the movable plate 11 disappears, the springs rebound to restore the positions of the two movable plates 11. The top and bottom ends of the two springs are respectively fixedly connected to the opposite surfaces of the top movable plate 11 and the bottom movable plate 11. The ends of the two pressing blocks 12 located outside the second docking shaft 22 are both hemispherical, increasing the contact area between the pressing block 12 and the finger.
[0034] As Figure 1 and Figure 4As shown, the front sides of the two movable plates 7 are fixedly connected with connecting blocks 16, the top of the fixed platform 1 is fixedly connected with a connecting rod 14, and the bottom of the connecting block 16 is rotatably connected with a moving wheel 15, and a rolling groove is provided at the top of the fixed platform 1 below the connecting rod 14, and the moving wheel 15 is located inside the rolling groove. When the movable plate 7 moves, it will drive the connecting block 16 to move, and the connecting block 16 will move outside the connecting rod 14 and drive the moving wheel 15 to roll inside the rolling groove, which can evenly distribute the resistance of the movement of the movable plate 7, so that the movable plate 7 can translate more stably.
[0035] like Figure 1 As shown, both sides of the handle 17 are fixedly connected to the bottom of the fixed platform 1 with support plates, the support plates are triangular in shape, and can enhance the supporting performance of the handle 17 on the fixed platform 1. The outside below the handle 17 is fixedly connected with anti-slip grooves 18 to increase the friction between the hand 17 and the palm to prevent slipping. The bottom end of the handle 17 is fixedly connected with a hanging block 19.
[0036] like Figure 1 and Figure 2 As shown, the outer rings of the bending roller 4 and the limiting roller 8 are both provided with "U"-shaped annular grooves. The depths and opening and closing angles of the annular grooves on the outside of the bending rollers 4 and the limiting rollers 8 of different specifications are also different. The bending rollers 4 and the limiting rollers 8 can be disassembled so that the annular grooves of the bending rollers 4 and the limiting rollers 8 are adapted to the specifications of the steel bars currently being bent. When bending, the annular grooves fit the steel bars, thereby increasing the stress-bearing area of the steel bars during bending, thereby ensuring the bending effect and preventing the bending rollers 4 and the limiting rollers 8 from being subjected to excessive stress and cracking.
[0037] The working principle of the utility model is as follows: when it is necessary to bend the steel bar, the top and bottom of the steel bar can be respectively contacted with the bottom of the bending roller 4 and the top of the limit roller 8 by holding the handle, and the hydraulic rod 2 is started to make the bending roller 4 move downward, and the bending roller 4 can cooperate with the limit roller 8 to bend the steel bar. This way of bending steel bars by hand can greatly meet the actual needs of the construction site, improves the practicality of the bending equipment, and is worthy of popularization and use. When it is necessary to bend steel bars of different thicknesses, the transmission motor 5 can be started, so that the transmission motor 5 drives the transmission screw 6 to rotate, so that the transmission screw The movable plate 7 outside the rod 6 drives the two limiting rollers 8 to move outward, thereby increasing the distance between the limiting roller 8 and the bending roller 4, so that the device can accommodate steel bars with larger diameters internally. When bending steel bars with larger diameters, the pressing block 12 in the installation mechanism can be pressed to separate the two docking rods, so that the bending roller 4 and the limiting roller 8 can be replaced, so that the depth and angle of the "U" groove of the outer circle of the bending roller 4 and the limiting roller 8 can be replaced, making them more suitable for the steel bars, thereby increasing the force-bearing area of the steel bars during bending, ensuring the bending effect and preventing the bending roller 4 and the limiting roller 8 from being cracked due to excessive force.
[0038] The above content is a further detailed description of the present utility model in combination with specific implementation manners. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
