[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1: Reference Figures 1-4 The illustrated embodiment shows an angle-adjustable steel bar bending device, comprising a workbench 1 and a turntable 2. The turntable 2 is rotatably connected to the workbench 1 and driven by a bending motor 16. A fixed column 3 and a bending column 4 are provided on the turntable 2. The fixed column 3 is coaxially arranged with the turntable 2. The turntable 2 is also provided with a second adjustment component for adjusting the distance between the bending column 4 and the fixed column 3.

[0022] The workbench 1 is further provided with a control unit, which controls the operation of the bending motor 16 so that the turntable 2 drives the bending column 4 to bend the steel bar according to demand; the control unit adopts a PLC control unit, which can input the bending angle of the steel bar into the control unit and control the turntable 2 to electrically drive the bending column 4 to bend the steel bar;

[0023] The workbench 1 is also provided with a fixed plate 5 and a movable plate 6 for bending the steel bars, and the fixed plate 5 and the movable plate 6 correspond to the positions of the fixed column 3 and the bending column 4 respectively;

[0024] The workbench 1 adjusts the distance between the movable plate 6 and the fixed plate 5 through the first adjustment component. The second adjustment component is connected to the first adjustment component through a gear set. When the first adjustment component is in operation, the gear set drives the second adjustment component to operate, thereby achieving simultaneous movement of the movable plate 6 and the bending column 4. The movable plate 6 limits the position of the steel bar, and the bending column 4 cooperates with the fixed column 3 to improve the bending accuracy of the steel bar.

[0025] First regulating component: Figure 4 As shown, it is used to adjust the position relationship of the movable plate 6 on the workbench 1 so that it cooperates with the fixed plate 5 to limit the bending steel bars;

[0026] The first adjustment component includes a first screw 10, the movable plate 6 is slidably connected to the workbench 1, the first screw 10 is rotatably connected to the workbench 1, and a first threaded hole engaged with the first screw 10 is opened on the movable plate 6. The first screw 10 is driven by a servo motor 13.

[0027] Second regulating component: Figure 3 As shown, it is used to adjust the position relationship of the bending column 4 on the turntable 2 so that the spacing between the bending column 4 and the fixed column 3 is adapted to the diameter of the steel bar to be bent, thereby improving the accuracy of the steel bar bending;

[0028] The second adjustment component includes a second screw 17 and a slider 15. The turntable 2 is provided with a slide groove 8 for the slider 15 to slide. The workbench 1 is also provided with a scale line 9 corresponding to the position of the slide groove 8. The second screw 17 is also rotatably connected in the slide groove 8. The slider 15 is provided with a second threaded hole that engages with the second screw 17.

[0029] The gear set includes a first gear 12, a second gear 11, and a transmission gear 14. The first gear 12 is mounted on the first screw 10, and the second gear 11 is mounted on the second screw 17. The transmission gear 14 is rotatably connected to the workbench 1, and the transmission gear 14 transmits the power from the first gear 12 to the second gear 11. Through the linkage of the gear set, the movable plate 6 and the bending column 4 move synchronously.

[0030] The fixed plate 5 is also hinged with a protective plate 7, and the movable plate 6 is provided with a through hole corresponding to the position of the protective plate 7. In the initial state of the equipment, the protective plate 7 is not in the through hole of the movable plate 6, and the movable plate 6 does not limit the protective plate 7. The staff can rotate the protective plate 7 to load the steel bars to be bent between the movable plate 6 and the fixed plate 5; when the movable plate 6 moves, the protective plate 7 is embedded in the through hole of the movable plate 6. At this time, the protective plate 7, the movable plate 6, the fixed plate 5 and the workbench 1 are enclosed into a rectangular frame to limit the steel bars to avoid prying the steel bars during bending, which may cause injuries to the staff.

[0031] The working principle of the utility model is as follows: when using the device, the device is connected to the power supply, and the angle parameters are input into the control unit according to the required bending angle. The steel bar is passed between the fixed plate 5 and the movable plate 6, and then passed between the fixed column 3 and the bending column 4. The servo motor 13 is started by the control unit, so that the servo motor 13 drives the first screw 10 to rotate. Through the meshing relationship between the first screw 10 and the first threaded hole on the movable plate 6, the movable plate 6 is driven to move toward the fixed plate 5, so that the two are in contact with the steel bar. At the same time, the protective plate 7 on the fixed plate 5 is inserted into the through hole on the movable plate 6;

[0032] As the first screw 10 rotates, it drives the first gear 12 to rotate, and through the transmission gear 14, drives the second gear 11 to rotate, thereby driving the first screw 10 to rotate. Through the relationship between the first screw 10 and the second threaded hole on the slider 15, the slider 15 drives the bending column 4 to move toward the fixed column 3, so that the two are in contact with the steel bar and are ready for bending processing;

[0033] The bending motor 16 is controlled to rotate, driving the turntable 2 to rotate, thereby driving the bending column 4 to bend the steel bars; when the turntable 2 rotates, the second gear 11 is driven to rotate at the same time. Since the gear set has completed the transmission when the turntable 2 rotates, when the turntable 2 is reset, the second gear 11 and the transmission gear 14 will be in a meshing state again, which will not affect the unloading of the steel bars and the next bending process.

[0034] The electromechanical connection involved in the present invention is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments, which belongs to common knowledge.

[0035] Components not described in detail herein are prior art.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
