Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Reference Figures 1-4 The adjustable angle rebar bending device shown includes a body 1 and a turntable 2. The turntable 2 is rotatably connected to the body 1, and a servo motor that drives the turntable 2 to rotate is also provided inside the body 1.

[0023] The machine body 1 is also provided with a mounting base 4, the center of which coincides with the axis of the turntable 2. The mounting base 4 is provided with a fixed roller 5, which is provided in two sets. Under the action of the drive mechanism, the two sets of fixed rollers 5 can be adjusted to move towards each other or away from each other.

[0024] like Figure 2As shown, the driving mechanism includes a rotating rod 20 and a slider 21. The slider 21 is installed at the bottom of the fixed roller 5. The mounting base 4 has a groove 19 for the slider 21 to slide. The rotating rod 20 is rotatably connected in the groove 19. The two ends of the rotating rod 20 are flush with the end face of the mounting base 4, and one end of the rotating rod 20 has an internal hexagonal groove. The rotating rod 20 is rotated through the internal hexagonal groove. The rotating rod 20 has threaded sections with opposite directions of rotation. The slider 21 has a threaded hole that meshes with the slider 21. Through the meshing relationship between the threaded hole and the threaded section, the two sets of sliders 21 can be driven to move towards or away from each other.

[0025] The turntable 2 is also provided with mounting holes 3 for mounting bending rollers 6, and the mounting holes 3 are provided in multiple sets;

[0026] The machine body 1 is also provided with an end face flushing component and a limiting component. The end face flushing component and the limiting component are located on the left and right sides of the turntable 2, respectively, to assist in bending the reinforcing bars.

[0027] like Figure 3 As shown, the end face flushing assembly includes a support base 7 and an end plate 9. The support base 7 is mounted on the machine body 1 and located on the left side of the turntable 2. A through groove 14 is provided on the support base 7, and a support frame 8 is slidably connected in the through groove 14. The support frame 8 is driven by a cylinder 10. The through groove 14 is provided to ensure that the support frame 8 operates stably under the drive of the cylinder 10 and to avoid deviation. The end plate 9 is provided on the opposite end of the support frame 8 and the turntable 2 for aligning the end faces of the reinforcing bars. The cylinder 10 drives the end plate 9 to move, which can push the end of the reinforcing bars to move, so that multiple sets of reinforcing bars are flush, thereby ensuring the bending accuracy of the reinforcing bars.

[0028] like Figure 4 As shown, the limiting component includes a clamping plate 12 and a telescopic cylinder 13. A pad 11 is installed on the machine body 1. The pad 11 is located on the right side of the turntable 2. The clamping plate 12 is provided on the pad 11. The clamping plate 12 slides on the pad 11 under the drive of the telescopic cylinder 13. There are two sets of clamping plates 12, which are symmetrically arranged.

[0029] The two sets of clamping plates 12 are also provided with receiving grooves 18 on their facing surfaces. A clamping block 15 is slidably connected in the receiving groove 18. A connecting post 16 is provided on the facing surface of the clamping block 15 and the clamping plate 12. The connecting post 16 is T-shaped. The end of the connecting post 16 protrudes from the receiving groove 18 and a spring 17 is provided between it and the clamping plate 12.

[0030] By cooperating with the clamping block 15 and the spring 17, the reinforcing bar can be pre-limited. The positional relationship of the reinforcing bar can be adjusted by the end face flush assembly. The reinforcing bar is always in a limited state, avoiding movement or rolling due to inertia.

[0031] The working principle of this utility model is as follows: When in use, the equipment is connected to power and connected to an external PLC control center. The PLC control center controls the opening and closing of the electrical components in the equipment.

[0032] According to the diameter of the steel bar to be bent, the bending roller 6 is installed in the mounting hole 3 on the turntable 2 and fixed. The distance between the two sets of fixed rollers 5 is adjusted. The rotating rod 20 is rotated through the internal hexagonal groove so that it rotates on the mounting base 4. Through the meshing relationship between the threaded section on the rotating rod 20 and the threaded hole on the slider 21, the two sets of sliders 21 are driven to move towards or away from each other in the slide groove 19, thereby adjusting the distance between the two sets of fixed rollers 5.

[0033] One end of the reinforcing bar is placed on the mounting base 4 and positioned between the two sets of fixed rollers 5. At the same time, the pad 11 supports the reinforcing bar, keeping it horizontal, and pushes the reinforcing bar to the left so that its end contacts the end plate 9. The telescopic cylinder 13 is controlled to extend, driving the two sets of clamping plates 12 to move towards each other. The clamping block 15 on the clamping plate 12 first contacts the reinforcing bar. The telescopic cylinder 13 continues to extend, and the clamping block 15 slides in the receiving groove 18. The spring 17 is stretched. At this time, the clamping plate 12 has not yet contacted the reinforcing bar. With the cooperation of the spring 17 and the clamping block 15, the reinforcing bar is pre-clamped.

[0034] The control cylinder 10 retracts, causing the support frame 8 to slide in the through groove 14 on the support seat 7, thereby moving the end plate 9 and pushing the end face of the reinforcing bar to make the end faces of multiple sets of reinforcing bars flush, while adjusting the bending position of the reinforcing bars; the control cylinder 13 extends, causing the clamping block 15 to retract into the receiving groove 18, the clamping plate 12 to contact the reinforcing bar and clamp and limit it, the control servo motor to rotate, causing the turntable 2 to rotate on the machine body 1, thereby causing the bending roller 6 to rotate, and cooperating with the fixed roller 5 to complete the bending process of the reinforcing bar.
