[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-6 A steel bar bending device for civil building construction includes a supporting base plate 1. A vertical plate 2 is fixedly connected to one side of the supporting base plate 1. A fixed placement plate 3 and a position-adjustable movable positioning plate 4 are fixedly connected to the vertical plate 2. The fixed placement plate 3 and the movable positioning plate 4 are adapted to each other. A rotating seat 5 adapted to the positions of the fixed placement plate 3 and the movable positioning plate 4 is rotatably connected to one side of the vertical plate 2. A fixed bending column 6 with a fixed position is rotatably connected to one end of the rotating seat 5. A rotating bending column 7 that can rotate and is adapted to the fixed bending column 6 is provided on one side of the rotating seat 5. A rotating shaft 8 that penetrates the vertical plate 2 is fixedly installed on the side of the rotating seat 5 away from the fixed bending column 6. The rotating shaft 8 is concentric with the fixed bending column 6. One end of the rotating shaft 8 extends beyond the vertical plate 2. A bending rod 11 is provided on the side away from the fixed bending column 6. An electric bending unit 13, which can be detached and is used to drive the rotating shaft 8, is provided on the side of the vertical plate 2 away from the fixed bending column 6. A snap ring 10 is fixedly connected to the end of the bending rod 11 near the rotating shaft 8. A polygonal snap block 9 that is adapted to the snap ring 10 is fixedly installed on the end of the rotating shaft 8 that extends beyond the side of the vertical plate 2. The electric bending unit 13 includes a first gear 12 fixedly installed on the side of the rotating shaft 8 that extends beyond the side of the vertical plate 2. A mounting bracket 14 is installed on the side of the vertical plate 2 away from the fixed bending column 6 by fasteners. A drive motor 15 is fixedly installed on the mounting bracket 14. A second gear 16 that meshes with the first gear 12 is fixedly installed on the output end of the drive motor 15.
[0029] Specifically, when bending thinner steel bars, one end of the steel bar is placed between the fixed placement plate 3 and the movable positioning plate 4, with the bending position of the steel bar located between the fixed bending column 6 and the rotating bending column 7. The bending rod 11 is installed by sleeved snap ring 10 on the side of snap block 9. Rotating the bending rod 11 causes the rotating shaft 8 to rotate, which in turn causes the rotating seat 5 to rotate. Since the rotating shaft 8 and the fixed bending column 6 are concentric, when the rotating seat 5 rotates, it causes the rotating bending column 7 to rotate along the fixed bending column 6, thus achieving... For bending of steel bars, if it is necessary to bend thicker steel bars, the mounting bracket 14 is installed on one side of the vertical plate 2 using fasteners. After installation, the second gear 16 meshes with the first gear 12, and the bending position of the thicker steel bar is placed between the fixed bending column 6 and the rotating bending column 7. By starting the drive motor 15, the output end of the drive motor 15 drives the second gear 16 to rotate, the second gear 16 drives the first gear 12 to rotate, and the first gear 12 drives the rotating shaft 8 to rotate, thereby achieving the effect of bending the thicker steel bar and improving the applicability of the overall bending device.
[0030] As a technical optimization of this utility model, a first sliding block 17 is fixedly installed on one side of the movable positioning plate 4, and a first sliding groove 18 adapted to the first sliding block 17 is opened on one side of the vertical plate 2. A first adjusting threaded rod 19 extending into the first sliding groove 18 is rotatably connected through the upper side of the vertical plate 2. The first adjusting threaded rod 19 passes through the first sliding block 17 and is threadedly connected to it. A first limiting nut 20 is threadedly connected to the side of the first adjusting threaded rod 19.
[0031] Specifically, when it is necessary to bend steel bars of different thicknesses, the first adjusting threaded rod 19 is rotated. When the first adjusting threaded rod 19 rotates, it drives the first sliding block 17 to move within the first sliding groove 18. The first sliding block 17 drives the movable positioning plate 4 to move, thereby adjusting the distance between the fixed placement plate 3 and the movable positioning plate 4. Then, the first limiting nut 20 is tightened to limit and fix the position of the first adjusting threaded rod 19. This allows for the placement and clamping of steel bars of different thicknesses, improving the applicability of the overall device.
[0032] As a technical optimization of this utility model, one end of the rotating bending column 7 is rotatably connected to a second sliding block 21, and a second sliding groove 22 adapted to the second sliding block 21 is opened on one side of the rotating seat 5. One end of the rotating seat 5 is rotatably connected to a second adjusting threaded rod 23 extending into the second sliding groove 22. The second adjusting threaded rod 23 passes through the second sliding block 21 and is threadedly connected to it. A second limiting nut 24 is threadedly connected to the side of the second adjusting threaded rod 23.
[0033] Specifically, when different steel bars need to be bent, the second adjusting threaded rod 23 is rotated. When the second adjusting threaded rod 23 rotates, it drives the second sliding block 21 to move in the second sliding groove 22. The second sliding block 21 drives the rotating bending column 7 to move, thereby adjusting the distance between the fixed bending column 6 and the rotating bending column 7. Then, the second limiting nut 24 is tightened to limit and fix the position of the second adjusting threaded rod 23, thereby improving the applicability of the overall device.
[0034] As a technical optimization of this utility model, an elastic frame 25 with elasticity is fixedly installed on the upper part of the vertical plate 2. The elastic frame 25 is adapted to the bending rod 11. The upper end of the bending rod 11 extends beyond the upper side of the vertical plate 2. The elastic frame 25 is elastic and one side of it is adapted to the side of the bending rod 11. It is used to temporarily fix the position of the bending rod 11 to prevent the bending rod 11 from shaking when the operator places the steel bar, so as to facilitate the operator's operation.
[0035] As a technical optimization of this utility model, the bearing base plate 1 is provided with a number of mounting holes. The bearing base plate 1 is installed on the ground through the mounting holes and fasteners. The bearing base plate 1 is fixedly installed on the ground by the cooperation of the fasteners and the mounting holes on the bearing base plate 1, thereby improving the stability of the overall device when bending the steel bars.
[0036] The drive motor 15 mentioned above can be purchased from the market. It is a mature technology that has been fully disclosed, so it will not be repeated in the specification. The drive motor 15 is equipped with a power connection cable, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power connection cable. The main controller can be a conventional known device such as a computer that plays a control role.
