[0027] A bending device for construction engineering, comprising a bottom plate 1, a semicircular frame 6 is fixedly connected to the top of the bottom plate 1, a sensing mechanism 8 is arranged inside the semicircular frame 6, a bending mechanism 9 is arranged at the bottom of the bottom plate 1, an arc groove 7 is opened at the top of the bottom plate 1, and a limit plate 3 is arranged on the right side of the top of the bottom plate 1;

[0031] Specifically, Figure 1 As shown, a connecting plate 4 is fixedly connected to the right side of the semicircular frame 6 , a bracket 5 is fixedly connected to the front and rear sides of the right side of the connecting plate 4 , and the top of the bracket 5 is fixedly connected to the top of the bottom plate 1 .

[0032] In this embodiment: by sliding the movable column 802 inside the semicircular frame 6 to the tip position pointing to the angle at which the steel bar needs to be bent, then holding the fixed block 18 and the anti-slip strip 19, and then locking the threaded column 801, the top of the fixed plate 803 is in close contact with the bottom of the semicircular frame 6 to increase the friction, the movable column 802, the fixed plate 803 and the sensor 804 can be limited, and the semicircular frame 6 is stably supported on the top of the base plate 1 by the bracket 5.

[0033] Specifically, Figure 4 As shown, the bending mechanism 9 includes a first limit button 901, a first support wheel 902, a first fixed rod 903, a rotating plate 904, a reducer 905 and a servo motor 906. The first support wheel 902 is rotatably mounted on the surface of the first fixed rod 903. The bottom of the first limit button 901 extends to the inside of the first fixed rod 903 and is connected to the internal thread of the first fixed rod 903. The bottom of the first fixed rod 903 is fixedly connected to the top of the rotating plate 904. The bottom of the rotating plate 904 is fixedly connected to the top of the output shaft of the reducer 905. The top of the output shaft of the servo motor 906 is fixedly connected to the input shaft of the reducer 905. The first support wheel 902 is movably arranged inside the arc groove 7.

[0034] Specifically, Figure 2As shown, a second fixing rod 11 is fixedly connected to the top of the base plate 1, a second supporting wheel 12 is fixedly connected to the surface of the second fixing rod 11, a second limit button 13 is arranged on the top of the second fixing rod 11, and the bottom of the second limit button 13 extends to the interior of the second fixing rod 11 and is connected to the internal thread of the second fixing rod 11.

[0035] Specifically, Figure 2 and Figure 3 As shown, a support plate 16 is fixedly connected to the right side of the top of the base plate 1, an electric telescopic rod 15 is fixedly connected to the left side of the support plate 16, a fixing frame 14 is fixedly connected to the left side of the telescopic end of the electric telescopic rod 15, and the right side of the limiting plate 3 is fixedly connected to the left side of the fixing frame 14.

[0036] Specifically, Figure 2 As shown, the bottom of the base plate 1 is fixedly connected with a support leg 2, the number of the support legs 2 is several and evenly distributed at the bottom of the base plate 1, a support plate 10 is provided at the bottom of the base plate 1, and the side of the support plate 10 close to the support leg 2 is fixedly connected to the support leg 2, and the bottom of the servo motor 906 is fixedly connected to the top of the support plate 10.

[0037] In this embodiment: by controlling the servo motor 906 to rotate, the power of the output shaft of the servo motor 906 is transmitted to the reducer 905. After the reducer 905 adjusts the speed and increases the torque, its output shaft drives the rotating plate 904 to rotate, and the first fixing rod 903 on the top of the rotating plate 904 and the first supporting wheel 902 sleeved thereon rotate accordingly, and the first supporting wheel 902 moves in the arc groove 7. Since the steel bar to be bent is located between the first supporting wheel 902 and the second supporting wheel 12, the rotation of the first supporting wheel 902 will push the steel bar to bend around the contact point with the second supporting wheel 12 until the steel bar is bent to the bottom of the sensor 804. The sensor 804 will transmit the signal to the built-in control system. At this time, the control system will control the bending mechanism 9 to stop the bending action according to the preset program, so as to realize precise bending angle control. By controlling the extension of the telescopic end of the electric telescopic rod 15 so that the surface of the limit plate 3 contacts the surface of the steel bar to be bent, the steel bar can be made more stable during the bending process. By removing the first limit button 901 and the second limit button 13, the first support wheel 902 and the second support wheel 12 can be replaced when they are worn. The bottom plate 1 is stably supported by the support leg 2 and contacts the support leg 2 through the support plate 10. The support plate 10 can stably support the servo motor 906.

[0038] Working principle: With the base plate 1 as the basic platform, several legs 2 at the bottom of the base plate 1 provide stable support, and the legs 2 are connected to the support plate 10, so as to conveniently support the servo motor 906. The semicircular frame 6 at the top of the base plate 1 is an important structural component, and its right side is fixedly connected to the base plate 1 through the connecting plate 4 and the bracket 5 to form a stable frame structure, which provides a basic framework for the bending operation. The position of the movable column 802, the fixed plate 803 and the sensor 804 at the bottom of the fixed plate 803 are adjusted according to the bending angle of the steel bar. By observing the scale groove 17 and the position of the tip of the movable column 802 pointing to the angle at which the steel bar needs to be bent, the anti-slip strip 19 and the fixed block 18 are held, and then the threaded column 801 is rotated to move the threaded column 801 upward. The top of the fixed plate 803 is made to be in close contact with the bottom of the semicircular frame 6, so that the movable column 802, the fixed plate 803 and the sensor 804 can be limited, and then the steel bar to be bent is placed between the first support wheel 902 and the second support wheel 12 on the opposite side, so that the steel bar to be bent is in contact with the surface of the second support wheel 12, and then the telescopic end of the electric telescopic rod 15 is controlled to extend to the left, so that the limiting plate 3 can be moved to contact with the steel bar to be bent, and the steel bar to be bent is kept parallel to the bottom plate 1, and then the servo motor 906 is controlled to rotate, and the power of the output shaft of the servo motor 906 is transmitted to the reducer 905. After the reducer 905 adjusts the speed and increases the torque, its output shaft drives the rotating plate 904 to rotate, and the rotating plate 9 04, the first fixed rod 903 at the top and the first support wheel 902 mounted thereon rotate accordingly, and the first support wheel 902 moves in the arc groove 7. Since the steel bar to be bent is located between the first support wheel 902 and the second support wheel 12, the rotation of the first support wheel 902 will push the steel bar to bend around the contact point with the second support wheel 12. When the steel bar moves to the bottom of the sensor 804 at the bottom of the moving column 802 during the bending process, the sensor 804 will transmit a signal to the built-in control system. At this time, the control system will control the bending mechanism 9 to stop the bending action according to a preset program, thereby achieving precise bending angle control. By using a servo motor 906, a reducer 905, an electric telescopic rod 15 and a sensor 80 4 can complete the precise bending of the steel bars of the construction project. It has a simple structure and does not require professional maintenance. It can also reduce the overall weight and the cost of bending the steel bars, thereby reducing the construction cost of the construction project. It avoids the problem that some existing equipment for bending steel bars is driven by a complex hydraulic system. High-quality hydraulic pumps, precision hydraulic valves, and hydraulic cylinders that can withstand high pressure all require high manufacturing costs and require more professional staff for maintenance. In addition, the overall weight is heavy, which affects the mobility and increases the construction cost of small-scale construction sites. It should be noted that the angle value between adjacent scale grooves 17 is 3, and the position of the movable column 802 and the sensor 804 can be adjusted according to needs.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
