[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example 1

[0023] Reference Figure 1 As shown, a simple structural column stirrup bending machine includes: a workbench 6, a turntable 8 disposed on the workbench 6 and capable of rotation, a support column 11 fixed to the workbench 6 and located at the center of the turntable 8, and a bending structure for bending stirrups, the bending structure including a bending member and a clamping member.

[0024] In this embodiment, multiple support columns are fixedly installed at the bottom of the worktable 6, which positions the worktable 6 at a convenient operating height and improves its stability. The turntable 8 can rotate around the abutment column 11 located at its center.

[0025] The clamping component includes: a mounting frame 14 fixedly installed on the workbench 6 and located on one side of the support column 11; the mounting frame 14 is provided with an internal threaded hole; a screw 13 connected to the internal threaded hole of the mounting frame 14; and a pressure plate 12 fixedly connected to the end of the screw 13 and pressing against the stirrups so that the stirrups abut against the support column 11. The pressure plate 12 is slidably connected to the mounting frame 14. In this embodiment, a rotating handle is provided at the outward end of the screw 13, and the pressure plate 12 is fixedly installed at the inner end of the screw 13. The pressure plate 12 can press against the stirrups so that the stirrups abut against the support column 11. A sliding block 17 is installed on the pressure plate 12, and a limit groove is opened on the mounting frame 14, so that the pressure plate 12 can slide in the direction of approaching or moving away from the support column 11. A rubber pad is installed on the pressure plate 12, so as to protect the stirrups.

[0026] The bending component includes a bending column 15 fixed to the turntable 8 and located on one side of the abutment column 11, and a bending handle 10 fixed to the bending column 15. By pulling the bending column 15 through the bending handle 10, the bending column 15 is rotated, which in turn drives the turntable 8 to rotate, thus saving effort.

[0027] Preferably, in this embodiment, the turntable 8 is located above the fixed plate 7, the fixed plate 7 is located above the workbench 6, and the turntable 8 and the fixed plate 7 are rotatably connected; a scale 9 is provided at the junction of the fixed plate 7 and the turntable 8, and the scale 9 is arranged in a ring, with the center of the ring of the scale 9 being the point where the steel bar and the bending point are located, generally the point where the steel bar and the abutment 11 are tangent. Example 2

[0028] Based on Example 1, such as Figure 1 and Figure 3 As shown, preferably, in this embodiment, the workbench 6 is also provided with a guide structure for guiding the stirrups.

[0029] Preferably, in this embodiment, the guide structure includes: three sets of first guide wheels 1 fixed on the workbench 6 and located on the same horizontal line as the mounting frame 14, connecting rods 3 connecting adjacent first guide wheels 1, and a plurality of second guide wheels 2 arranged at intervals with the plurality of first guide wheels 1, with connecting rods 3 also fixedly connected between adjacent second guide wheels 2.

[0030] The second guide wheel 2 is slidably connected to the workbench 6 and cooperates with the corresponding first guide wheel 1 to guide the stirrups. Example 3

[0031] Based on Example 2, such as Figure 2 and Figure 3 As shown, in this preferred embodiment, the workbench 6 is provided with an adjustment assembly, which includes a sliding groove 16 on the workbench 6, a threaded rod 4 in the sliding groove 16, a sliding block 17 threadedly connected to the threaded rod 4 and slidably connected to the sliding groove 16, and a locking handle 5 on the side wall of the workbench 6 and coaxially connected to the threaded rod 4. The second guide wheel 2 is fixedly connected to the sliding block 17. The threaded rod 4 is rotatably connected to the sliding groove 16. In this embodiment, the threaded rod 4 is provided with two sets of bearings, which are respectively located at both ends of the thread. The outer ring of the bearing is interference-fitted with the sliding groove 16, and the inner ring of the bearing is interference-fitted with the threaded rod 4.

[0032] When the locking handle 5 is rotated, the sliding block 17 moves linearly along the guide groove, and at the same time drives the second guide wheel 2 to move linearly. That is, the second guide wheel 2 can be controlled to move linearly by rotating the locking handle 5. The adjustment component is used to adjust the position of the second guide wheel 2, that is, to adjust the distance between the second guide wheel 2 and the first guide wheel 1 to accommodate steel bars of different diameters.

[0033] In this embodiment, a servo motor can also be used to replace the locking handle 5. The servo motor directly drives the threaded rod 4 to rotate, and the servo motor adjusts the distance between the second guide wheel 2 and the first guide wheel 1 to accommodate steel bars of different diameters.

[0034] When bending the stirrups, the reinforcing bar passes between the first guide wheel 1 and the second guide wheel 2 of the guide structure. Rotating the locking handle 5 or starting the servo motor adjusts the position of the sliding block 17, thereby adjusting the distance between the second guide wheel 2 and the first guide wheel 1 to clamp the reinforcing bar. Rotating the rotating handle at the end of the screw 13 pushes the pressure plate 12 to press the reinforcing bar against the support column 11. The bending handle 10 drives the bending column 15 to rotate, and the turntable 8 rotates synchronously to bend the reinforcing bar. The bending angle of the reinforcing bar is observed through the scale 9, and the bending is complete once it reaches the desired position.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
