Description

Technical Field

[0001] This application relates to the field of bending technology in building engineering, and in particular to an auxiliary device for bending in building engineering. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. In construction, steel bars are an indispensable building material, and bending them is required during the construction process.

[0003] In the process of bending steel bars in construction projects, the steel bars are usually bent manually by the workers, who then judge whether the bending range meets the requirements by visual inspection. This requires experienced workers to perform the bending work. However, relying on visual inspection for a long time will result in inaccurate bending range and poor bending effect.

[0004] Therefore, those skilled in the art have provided an auxiliary device for bending in building engineering to solve the problems mentioned in the background art. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides an auxiliary device for bending in building engineering.

[0006] The auxiliary device for bending in building engineering provided in this application adopts the following technical solution:

[0007] An auxiliary device for bending in construction engineering includes a workbench, a platform fixed to the upper end of the workbench, and a rotating shaft rotatably connected to the platform. The rotating shaft has a rotating table fixed to its outer wall. A bending head for bending reinforcing bars is fixed to one side of the upper end of the rotating platform. A baffle and a fixed seat are fixed to the upper surface of the workbench. A slider is slidably installed on the upper end of the fixed seat, and a positioning column is rotatably provided on the upper end of the slider.

[0008] The upper end of the fixed base is provided with a sliding groove, the lower end of the slider is slidably connected inside the sliding groove, the fixed base is rotatably connected with a screw, and the lower end of the slider is threadedly connected to the screw.

[0009] The upper end of the slider is fixed with a threaded rod, the upper end of the threaded rod is threadedly connected to a sleeve, and the lower end of the positioning pin is rotatably connected to the sleeve.

[0010] A nut is fixed to the outer wall of one end of the screw, and the outer surface of the nut is provided with a socket.

[0011] Two fixing blocks are fixed at the upper end of the workbench, and a roller for supporting the reinforcing bars is rotatably connected between the two fixing blocks.

[0012] A motor is fixedly installed inside the workbench. A second gear is fixed to the output shaft at the upper end of the motor, and a first gear is fixed to the lower end of the rotating shaft. The first gear and the second gear are meshed together.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. By placing three steel bars between the bending head and the rotating shaft, three steel bars can be bent with one rotation of the bending head, improving the efficiency of steel bar bending. During the bending process, the steel bars stop bending when they contact the positioning post. The positioning post limits the bending range of the steel bars, which is more accurate than the operator's visual judgment and experience. Furthermore, the rotation of the screw causes the slider to slide, adjusting the position of the positioning post on the fixed seat, thereby adjusting the bending range of the steel bars. This is beneficial for obtaining steel bars with different bending ranges according to the steel bar construction needs during the construction process. In addition, the positioning post and the slider can be detached and installed via a threaded rod and sleeve, making it convenient to remove and replace the positioning post.

[0019] 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.

[0020] like Figs. 1-3As shown, this application discloses an auxiliary device for bending steel bars in construction engineering, including a workbench 1, a platform 3 fixed to the upper end of the workbench 1, and a rotating shaft 7 rotatably connected to the platform 3. A rotating table 6 is fixed to the outer wall of the rotating shaft 7. A bending head 8 for bending steel bars 11 is fixed to one side of the upper end of the rotating table 6. A baffle 9 and a fixed seat 4 are fixed to the upper surface of the workbench 1. A slider 14 is slidably installed on the upper end of the fixed seat 4. A positioning post 5 is rotatably set on the upper end of the slider 14. A groove 2 is opened on the upper end of the fixed seat 4. The lower end of the slider 14 is slidably connected to the groove 2. A screw 13 is rotatably connected to the fixed seat 4. The lower end of the slider 14 is threadedly connected to the screw 13. The operator can hold and stack three steel bars 11 at a time, place them between the bending head 8 and the rotating shaft 7, block one side of the steel bars 11 by the baffle 9, and then rotate the shaft 7 to bend the steel bars 11. The shaft 7 rotates counterclockwise, causing the rotating table 6 and the bending head 8 to rotate counterclockwise as well. This causes the bending head 8 to simultaneously compress the three reinforcing bars 11 until they bend and contact the outer surface of the positioning column 5. The positioning column 5 then stops the bending of the reinforcing bars 11. At this point, the rotation of the shaft 7 and the rotating table 6 is stopped, and the bending of the three reinforcing bars 11 is assisted. The positioning column 5 restricts the bending position of the reinforcing bars 11, ensuring that each reinforcing bar 11 has the same bending radius for use in construction. In addition, the operator can rotate the screw 13 to move the slider 14 along the length of the fixed seat 4, thereby moving and adjusting the position of the positioning column 5. This allows for adjustment of the bending radius of the reinforcing bars 11, enabling the bending of the reinforcing bars 11 to be adjusted according to the construction requirements, thus facilitating the bending of the reinforcing bars 11.

[0021] A threaded rod 19 is fixed to the upper end of the slider 14. A sleeve 20 is threadedly connected to the upper end of the threaded rod 19. The lower end of the positioning post 5 is rotatably connected to the sleeve 20. The positioning post 5 is detachably mounted on the threaded rod 19 through the sleeve 20, which facilitates the disassembly and replacement of the positioning post 5. In addition, the positioning post 5 and the sleeve 20 are rotatably set, and the positioning post 5 can be rotated to adjust other surfaces to contact the bent steel bar 11, thereby limiting the bending range of the steel bar 11.

[0022] A nut 18 is fixed to the outer wall of one end of the screw 13. The outer surface of the nut 18 is provided with a hole 21 to facilitate the rotation of the screw 13.

[0023] Two fixed blocks 10 are fixed at the upper end of the workbench 1, and a roller 12 for supporting the steel bar 11 is rotatably connected between the two fixed blocks 10. The roller 12 facilitates the support of the steel bar 11 for bending work, and the rotatable setting of the roller 12 reduces the friction between the roller 11 and the steel bar 11 during the bending process.

[0024] A motor 15 is fixedly installed inside the workbench 1. A second gear 17 is fixed to the output shaft at the upper end of the motor 15, and a first gear 16 is fixed to the lower end of the rotating shaft 7. The first gear 16 and the second gear 17 are meshed together. By controlling the operation of the motor 15, the second gear 17 is driven to rotate, which in turn drives the first gear 16 to rotate, thereby driving the rotating shaft 7 and the rotating table 6 to rotate, so that the bending head 8 rotates to bend the steel bar 11. The gear ratio of the second gear 17 to the first gear 16 is 1:3, which is used to drive the rotating table 6 and the bending head 8 to rotate at low speed. After the steel bar 11 is bent and contacts the positioning column 5, the operation of the motor 15 is stopped.

[0025] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] Working principle: The operator can hold three steel bars 11 stacked together at once and place them between the bending head 8 and the rotating shaft 7. The baffle 9 blocks one side of the steel bars 11. By controlling the motor 15, the second gear 17 is driven to rotate, which in turn drives the first gear 16 to rotate. This causes the rotating shaft 7 and the rotating table 6 to rotate counterclockwise, which in turn drives the bending head 8 to rotate counterclockwise. The bending head 8 simultaneously squeezes the three steel bars 11 until they bend and contact the outer surface of the positioning column 5. Then the rotation of the rotating shaft 7 and the rotating table 6 is stopped, and the bending of the three steel bars 11 is assisted.
