[0001] This utility model relates to the field of steel bar straightening tooling technology, and in particular to a steel bar straightening tooling for construction. Background Technology

[0002] Reinforcing bars refer to a type of steel used in reinforced concrete and prestressed reinforced concrete. Straightening reinforcing bars is an important step in the processing of reinforcing bars, the main purpose of which is to straighten bent or coiled reinforcing bars to meet the requirements of construction projects.

[0003] A search of Chinese patent CN218946208U reveals a rebar straightening machine, comprising a machine body, a propulsion assembly, and a straightening assembly. The machine body includes an operating table, a mounting base, and an adjusting component. The adjusting component includes a rotating rod, an adjusting gear, and an adjusting rack. A limiting groove is formed along the length of the operating table. One end of the mounting base extends into the limiting groove. The adjusting rack is evenly spaced on the surface of the mounting base extending into the limiting groove, and the length direction of the adjusting rack is perpendicular to the length direction of the mounting base. A rotating groove is formed on one side of the limiting groove, and the rotating rod is rotatably connected in the rotating groove. The adjusting gear is spaced along the length of the rotating rod and meshes with the adjusting rack. A handle is provided at one end of the rotating rod. The propulsion assembly and the straightening assembly are spaced along the length of the rotating rod on the mounting base. The propulsion assembly is used to push the rebar to the other end, and the straightening assembly is used to straighten the rebar.

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned straightening machine: the existing technology can only adjust the steel bars in the same direction, resulting in poor adjustment effect. Moreover, the existing technology straightens the steel bars by pressing them with adjusting rollers and fixed rollers. During straightening, the adjusting rollers and fixed rollers are prone to loosening, which affects the straightening effect of the steel bars. Based on this, this utility model designs a steel bar straightening tool for construction to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel bar straightening fixture for construction, comprising a fixed base plate, a fixed column one and a fixed column two respectively installed on the top outer wall of the fixed base plate, a fixed side plate fixedly installed on both the fixed column one and the fixed column two, a supporting side plate installed on one side wall of the fixed side plate, a bidirectional threaded rod rotatably connected to the supporting side plate, a supporting base respectively connected to the outer thread of the bidirectional threaded rod, and a straightening wheel rotatably connected to the supporting base;

[0007] A drive shaft is rotatably connected to the support side plate. A drive gear is installed at one end of the drive shaft, and a driven gear is installed on the side wall of the bidirectional threaded rod. The drive gear and the driven gear are meshed together.

[0008] As a preferred embodiment, a limiting side plate is installed on one side wall of the supporting side plate, and the drive shaft and the bidirectional threaded rod are rotatably connected to the supporting side plate.

[0009] As a preferred embodiment, a threaded sleeve is installed on the side wall of the drive shaft, and an adjusting nut is connected to the thread on the outer surface of the threaded sleeve.

[0012] As a preferred embodiment, guide rods are respectively installed on the support side plates, and the support base is slidably engaged with the guide rods.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By turning the drive shaft, the bidirectional threaded rod can simultaneously drive the support base to move, so that the straightening wheel can abut against the steel bar. When the steel bar moves, the horizontally and vertically placed straightening wheels can effectively straighten the steel bar.

[0021] 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.

[0022] This utility model provides, for example Figure 1-4 The illustrated steel bar straightening fixture includes a fixed base plate 1. Fixed columns 1 and 2 are respectively installed on the top outer wall of the fixed base plate 1. Fixed side plates 4 are fixedly installed on both fixed columns 1 and 2. The fixed side plate 4 installed on the fixed column 2 is parallel to the upper surface of the fixed base plate 1, while the fixed side plate 4 installed on the fixed column 1 is perpendicular to the upper surface of the fixed base plate 1. A supporting side plate 5 is installed on one side wall of the fixed side plate 4. A bidirectional threaded rod 6 is rotatably connected to the supporting side plate 5. Support bases 7 are respectively connected to the threads on the outer surface of the bidirectional threaded rod 6. The threads on the outer surfaces of the two ends of the bidirectional threaded rod 6 are in opposite directions, so that when the bidirectional threaded rod 6 rotates, the two supporting bases 7 can rotate simultaneously, supporting... A straightening wheel 8 is rotatably connected to each base 7. Three straightening wheels 8 are installed on each support base 7. A drive shaft 9 is rotatably connected to the support side plate 5. A drive gear 10 is installed at one end of the drive shaft 9. A driven gear 11 is installed on the side wall of the bidirectional threaded rod 6. The drive gear 10 and the driven gear 11 are meshed together. When it is necessary to straighten the steel bar, the steel bar is first passed through the parallel straightening wheels 8 in sequence, and then passed through the longitudinal straightening wheels 8 in sequence. Then, by turning the drive shaft 9, the bidirectional threaded rod 6 can simultaneously drive the support base 7 to move, thereby driving the straightening wheels 8 to abut against the steel bar. When the steel bar is moved in the future, the horizontally and longitudinally placed straightening wheels 8 can effectively straighten the steel bar.

[0023] In this embodiment, as Figure 4As shown, a limiting side plate 14 is installed on one side wall of the support side plate 5. The drive shaft 9 and the bidirectional threaded rod 6 are rotatably connected to the support side plate 5. A threaded sleeve 12 is installed on the side wall of the drive shaft 9. An adjusting nut 13 is connected to the thread on the outer surface of the threaded sleeve 12. By turning the adjusting nut 13, one end of the adjusting nut 13 can abut against the limiting side plate 14, thereby fixing the drive shaft 9. This helps to further fix the bidirectional threaded rod 6 and prevents the straightening wheel 8 from loosening when straightening the steel bar, thus ensuring the straightening effect of the tool on the steel bar.

[0024] In this embodiment, as Figure 3 As shown, a support fixing plate 15 is installed on one side wall of the support base 7. Two support fixing plates 15 are respectively installed on two longitudinally placed support bases 7. A drive motor 18 is installed on one side wall of one support fixing plate 15. A drive wheel 16 is connected to the output end of the drive motor 18. A driven wheel 17 is rotatably connected to the other support fixing plate 15. When the longitudinally placed support base 7 is moved, the drive wheel 16 and the driven wheel 17 can simultaneously abut against the steel bar. Then the drive motor 18 drives the drive wheel 16 to rotate, thereby pulling the steel bar forward.

[0025] In this embodiment, as Figure 1 As shown, a guide base plate 19 is installed on the top outer wall of the fixed base plate 1, and a guide sleeve 20 is installed on the guide base plate 19. When straightening the reinforcing bar, the reinforcing bar can be guided by passing it through the guide sleeve 20, which helps to prevent the reinforcing bar from falling off the straightening wheel 8.

[0026] In this embodiment, as Figure 2 As shown, guide rods 21 are installed on the support side plate 5 respectively. The support base 7 is slidably engaged with the guide rods 21. The guide rods 21 can guide the support base 7, which helps to improve the stability of the support base 7 when it moves.

[0027] Working principle of this utility model: This utility model is a steel bar straightening tool for construction. The steel bar is passed through the parallel straightening wheels 8 in sequence, and then through the longitudinal straightening wheels 8 in sequence. By turning the drive shaft 9, the bidirectional threaded rod 6 can simultaneously drive the support base 7 to move, so that the straightening wheels 8 can abut against the steel bar. When the steel bar moves, the horizontally and longitudinally placed straightening wheels 8 can effectively straighten the steel bar.

[0028] Furthermore, by turning the adjusting nut 13, one end of it can be pressed against the limiting side plate 14, thereby fixing the drive shaft 9 and further fixing the bidirectional threaded rod 6, which helps to prevent the straightening wheel 8 from loosening when straightening the steel bar.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
