DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The following further describes the present utility model in detail with reference to the drawings.

[0020] As Figures 1 - 3 shown, a bending tool for building construction proposed by the present utility model includes a bottom plate 1, and further includes a spacing adjustment mechanism 2 and a supporting and indentation mechanism 3 provided on the bottom plate 1; the supporting and indentation mechanism 3 includes a support frame 4 and a fixed frame 5. The support frame 4 is connected to the spacing adjustment mechanism 2. A swing plate 6 is rotatably provided on the support frame 4. A placement component 7 is provided on the swing plate 6. The fixed frame 5 is provided on the bottom plate 1 and is arranged in an L shape. A hydraulic cylinder 8 is provided on the bottom wall of the fixed frame 5. A pressing block 9 is provided at the end of the hydraulic cylinder 8. By adjusting the spacing adjustment mechanism 2, the distance between the two placement components 7 is changed. The steel bar is placed on the placement component 7. The hydraulic cylinder 8 is started to push the pressing block 9 to move, bending the steel bar deforming. When the steel bar deforms, the middle section of the steel bar moves downward and bends, causing the swing plate 6 to deflect accordingly, so that the placement component 7 always fits with the steel bar, which can avoid the steel bar slipping due to the change of the steel bar support point position and ensure the stable use of the equipment.

[0021] As Figure 2 and 3 shown, the placement component 7 includes a chute 10 and a tray 11. The chute 10 is provided on the swing plate 6. A slider 12 is slidably provided in the chute 10. Springs 13 are provided between the slider 12 and the two side walls at the ends of the chute 10. The tray 11 is provided on the slider 12. During the deformation process of the steel bar, the tray 11 drives the slider 12 to slide on the chute 10 as the steel bar bends and moves. At the same time, the tray 11 drives the swing plate 6 to deflect. During this process, the contact position between the tray 11 and the steel bar always remains unchanged. After the steel bar is bent, when the hydraulic cylinder 8 retracts and the tray 11 is no longer stressed, the spring 13 squeezed by the slider 12 pushes the slider 12 to reset, thereby driving the tray 11 to reset for the next use.

[0022] As Figure 2As shown in the figure, the spacing adjustment mechanism 2 includes an adjustment groove 14 and a connecting block 15. The adjustment groove 14 is provided on the bottom plate 1. A bidirectional lead screw 16 is rotatably provided in the adjustment groove 14. One end of the bidirectional lead screw 16 is axially connected to a motor 17, and the motor 17 is fixedly installed on the side wall of the bottom plate 1. The connecting block 15 is slidably provided at both ends of the adjustment groove 14, and the connecting block 15 is threadedly connected to the bidirectional lead screw 16. The support frame 4 is provided on the top wall of the connecting block 15. Starting the motor 17 drives the bidirectional lead screw 16 to rotate. The bidirectional lead screw 16 drives the connecting block 15 to move, and the connecting block 15 drives the support frame 4 to move, so as to adjust the distance between the swing plate 6 and the support plate 11, facilitating the adjustment of the support positions on both sides when the steel bar is bent, and thus being able to adjust the bending angle of the steel bar.

[0023] A counterweight block 18 is provided on the bottom wall of the swing plate 6, and the center of gravity is biased downward, so that the swing plate 6 can remain horizontal without external force, facilitating the placement of the steel bar.

[0024] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the gist of the present invention, they shall fall within the protection scope of the present invention.
