[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0022] According to Figure 1 , 2 , as shown in FIGS. 1, 2, and 3, a modular steel bar bending device is proposed in this embodiment, including a base 1. A second rocker arm 8 is provided at the upper end of the base 1, a first rocker arm 6 is provided at the upper end of the second rocker arm 8, a first rotating member for controlling the rotation of the second rocker arm 8 is provided at the upper end of the base 1, and a second rotating member for controlling the rotation of the first rocker arm 6 is provided at the lower end of the base 1;

[0023] A bracket 14 is provided above the first rocker arm 6. The bracket 14 is fixedly connected to the upper end of the base 1. Two movable rods 18 are provided at the upper end of the bracket 14, and an adjusting mechanism for adjusting the distance between the two movable rods 18 is provided at the upper end of the bracket 14;

[0024] When bending a steel bar, the steel bar is placed between the two movable rods 18. The adjusting mechanism adjusts the distance between the two movable rods 18 to fix the steel bar placed therein. Then, the second rotating member controls the rotation of the first rocker arm 6, and the first rotating member controls the rotation of the second rocker arm 8 to bend the steel bar from both ends.

[0025] A limiting wheel 20 is sleeved outside the movable rod 18. The limiting wheel 20 is slidably connected to the movable rod 18, and a positioning assembly is provided at the connection between the limiting wheel 20 and the movable rod 18.

[0026] When the steel bar is bent, the limiting wheel 20 on the outer side of the movable rod 18 will limit the steel bar to prevent the steel bar from tilting during the bending process and affecting the bending effect. The limiting wheel 20 is sleeved on the outer side of the movable rod 18 and is detachably connected to the movable rod 18 through a positioning component. The design that the limiting wheel 20 is easy to replace and the control method of the movement of the movable rod 18 enable the bending device to be applicable to steel bars of different diameters, with a wide range of applicability.

[0027] It should be further noted that a first pressing rod 7 is provided at the upper end of the first rocker arm 6, and a second pressing rod 9 is provided at the upper end of the second rocker arm 8. The first pressing rod 7 is fixedly connected to the upper end of the first rocker arm 6, and the second pressing rod 9 is fixedly connected to the upper end of the second rocker arm 8. The heights of the tops of the first pressing rod 7 and the second pressing rod 9 are higher than the height of the top of the limiting wheel 20.

[0028] During the bending process, the two movable rods 18 fix the steel bar in the center of the bending device through the limiting wheels 20. The second pressing rod 9 on the second rocker arm 8 and the first pressing rod 7 on the first rocker arm 6 are against the side of the steel bar. When the first pressing rod 7 on the first rocker arm 6 and the second pressing rod 9 at the upper end of the second rocker arm 8 deflect towards one side of the steel bar, the steel bar will be bent.

[0029] Regarding the adjusting mechanism:

[0030] The adjusting mechanism includes a chute 15 opened at the upper end of the bracket 14. A double-headed screw rod 17 and two nut seats 16 are arranged in the chute 15. The nut seats 16 are sleeved on the outer side of the double-headed screw rod 17 and are threadedly connected to the double-headed screw rod 17. The nut seats 16 are slidably connected to the chute 15. The nut seats 16 are fixedly connected to the lower ends of the movable rods 18. A handle for controlling the rotation of the double-headed screw rod 17 is provided on the outer side of the bracket 14. The outer side of the double-headed screw rod 17 has two sets of threads with opposite directions, and the two sets of threads are respectively matched with the two nut seats 16.

[0031] The working principle of the adjusting mechanism is:

[0032] Rotate the handle, and the handle drives the double-headed screw rod 17 to rotate. The double-headed screw rod 17 cooperates with the two nut seats 16 during rotation. Due to the different helix directions of the threads on the outer side of the double-headed screw rod 17, when the double-headed screw rod 17 rotates, the two nut seats 16 will move in opposite directions along the chute 15 to adjust the distance between the two movable rods 18.

[0033] Of course, in addition to manually controlling the rotation of the double-headed screw rod 17 by the handle, a motor can also be used to control the rotation of the double-headed screw rod 17 to improve the flexibility of controlling the movable rod 18, which will not be elaborated here.

[0034] Regarding the positioning component:

[0035] The positioning assembly includes a fixing bolt 21 , which is assembled on the side of the two limiting wheels 20 that are away from each other. The fixing bolt 21 penetrates into the limiting wheels 20 and is threadedly connected to the positioning groove 19 provided on the outside of the movable rod 18 .

[0036] The outer side of the movable rod 18 has a plurality of positioning slots 19 , and the positioning slots 19 are evenly arranged along the length of the movable rod 18 .

[0037] The positioning assembly adopts a bolt connection method to fix the position of the limiting wheel 20. When the limiting wheel 20 is removed from the movable rod 18 for replacement or height adjustment, the fixing bolt 21 on the outside of the limiting wheel 20 is unscrewed from the positioning groove 19 on the outside of the movable rod 18 to release the fixation between the limiting wheel 20 and the movable rod 18.

[0038] The specific structure of the first rotating member is described below.

[0039] The first rotating part includes a rotating drum 3, a second gear 5 and a first electric push rod 10. The rotating drum 3 is rotatably connected to the upper end of the base 1. The rotating drum 3 is fixedly connected to the second rocker arm 8. The second gear 5 is sleeved on the outside of the rotating drum 3 and fixedly connected to the rotating drum 3. The second gear 5 is engaged with the first gear plate 12 provided on the side of the base 1. The mounting end of the first electric push rod 10 is fixedly connected to the first gear plate 12.

[0040] comprehensive Figure 1 , the working principle of the first rotating part is:

[0041] When the first electric push rod 10 pushes the first gear plate 12, the teeth of the first gear plate 12 facing the second gear 5 will engage with the second gear 5, and the second gear 5 will be turned to rotate. Since the second gear 5 is fixed to the rotating drum 3 and the second rocker arm 8 is fixed to the rotating drum 3, when the second gear 5 rotates, the rotating drum 3 will also rotate with the second rocker arm 8.

[0042] The specific structure of the second rotating member is described below.

[0043] The second rotating part includes a rotating shaft 2, a first gear 4 and a second electric push rod 11. The upper end of the rotating shaft 2 is fixedly connected to the first rocker arm 6, and the lower end of the rotating shaft 2 passes through the rotating drum 3 and the base 1 and is fixedly connected to the first gear 4 provided at the lower end of the base 1. The rotating shaft 2 is rotatably connected to the rotating drum 3 and the base 1, and the first gear 4 is engaged with the second gear plate 13 provided on the side of the base 1. The mounting end of the second electric push rod 11 is fixedly connected to the base 1, and the output end of the second electric push rod 11 is fixedly connected to the second gear plate 13.

[0044] comprehensive Figure 1 , the working principle of the second rotating part is:

[0045] When the second electric push rod 11 pushes the second gear plate 13, the teeth of the second gear plate 13 facing the first gear 4 will engage with the first gear 4, and the first gear 4 will be turned to rotate. Since the first gear 4 is fixed to the rotating shaft 2, and the rotating shaft 2 is fixed to the first rocker arm 6, when the first gear 4 rotates, the rotating shaft 2 will also rotate with the first rocker arm 6.

[0046] How this application works:

[0047] When bending the steel bar, the steel bar is placed between the two movable rods 18, and the adjustment mechanism adjusts the distance between the two movable rods 18 to fix the steel bar placed therein. Then, the second rotating member controls the rotation of the first rocker arm 6, and the first rotating member controls the rotation of the second rocker arm 8 to bend the steel bar from both ends.

[0048] When bending the rebar, a limiting wheel 20 on the outside of the movable rod 18 limits the rebar's position, preventing it from tilting during the bending process and affecting the bending effect. The limiting wheel 20 fits over the outside of the movable rod 18 and is detachably connected to the movable rod 18 via a positioning assembly. The easily replaceable limiting wheel 20, combined with the control method for the movement of the movable rod 18, makes the bending device suitable for rebars of different diameters, providing a wide range of applications.
