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.

[0028] Example 1: As Figures 1 to 4 As shown, this embodiment provides a universal wire bending device, comprising: a device base 1, including a fixed column 3 fixedly arranged above it, a wire 4 arranged above the fixed column 3, a rotating pulley 2 rotatably connected to the periphery of the fixed column 3, a limiting block 7 fixedly arranged on the rotating pulley 2 for limiting the position, and a bending drive assembly arranged on one side of the limiting block 7; a sliding assembly, including a groove fixedly arranged above the fixed column 3, and a sliding guide rail 51 fixedly arranged on the groove for adjusting the bending angle of the wire 4 by the bending angle adjustment assembly; and a limiting assembly, including a fixed block 6 arranged above the fixed column 3 for mounting a fastening assembly to limit the bending of the wire 4.

[0029] In this embodiment, the device base 1, rotating ring 5, and fixing block 6 constitute the universal wire bending device involved in this application, realizing a universal wire bending device. In this application, any wire that needs to be bent can use this device, and this application does not limit the specific material category.

[0030] In this embodiment, the device base 1 serves as the foundation of the entire wire bending machine, providing a stable support platform for the various components above. It ensures that the entire device will not shake or shift due to external forces during the bending operation, thus guaranteeing the accuracy and stability of the bending work.

[0031] In this embodiment, the rotating pulley 2 is rotatably connected to the periphery of the fixed column 3. Its rotational characteristics allow the pull wire 4 to move more smoothly during the bending process, reducing the friction between the pull wire and the fixed column 3, avoiding damage to the pull wire due to excessive friction, and also improving the flexibility and smoothness of the bending operation.

[0032] It should be noted that the bending drive component arranged on one side of the limit block 7 makes the entire bending process more convenient. The operator can start the bending action simply by controlling the drive component, without the need for complicated manual adjustments or excessive external tools, thus reducing the difficulty of operation and labor intensity.

[0033] Specifically, the bending drive assembly includes: a bending handle 8, which is fixedly connected to the rotating pulley 2 by a stud 9, and one end of the bending handle 8 is attached to the upper surface of the fixed post 3 and rotates on the fixed post 3.

[0034] In this embodiment, the stud 9 tightly connects the bending handle 8 to the rotating pulley 2. This connection method has high stability and reliability and can withstand greater external forces during long-term and frequent bending operations.

[0035] Specifically, the bending angle adjustment component includes: threaded holes 54, evenly arranged on the sliding guide rail 51; a slider 52, which slides above the sliding guide rail 51, and a rotating ring 5 is fixedly installed above it; and screws 53, which are threaded to both sides of the slider 52 and pass through the threaded holes 54 to fix the slider 52.

[0036] In a preferred embodiment, the slider 52 slides above the sliding guide rail 51, which provides stable guidance for the movement of the slider 52, ensuring that the slider 52 can only move along a predetermined straight line, thus avoiding instability such as shaking or deviation during the adjustment process.

[0037] Example 2:

[0038] In order to further improve the fixed position of the pull wire 4, a rotating ring is arranged on the sliding guide rail 51 to fix the position of the pull wire 4 based on the embodiment 1.

[0041] Specifically, the fixed column 3 is provided with two groups of sliding guide rails 51, and the sliding guide rails 51 are provided with a plurality of groups of threaded holes 54 for adjusting the bending position of the pull wire 4.

[0042] As a preferred embodiment, the two groups of sliding guide rails 51 are fixed on the fixed column 3, which not only provides a movement track for the adjusting component, but also enhances the structure of the fixed column 3 to some extent. During the bending operation, when subjected to external force, the sliding guide rails 51 can share part of the force, reducing the pressure borne by the fixed column 3, avoiding problems such as deformation or damage due to excessive local stress, and ensuring the stability and reliability of the entire device structure.

[0043] Specifically, the rotating ring 5 is located on one side of the fixed block 6, and the pull wire 4 is bent through the gap formed by the rotating ring 5 and the fixed block 6 and the gap formed by the fixed block 6 and the bending handle 8.

[0044] It should be noted that the pull wire 4 is bent through the gap formed by the rotating ring 5 and the fixed block 6 and the gap formed by the fixed block 6 and the bending handle 8. Such gaps play a limiting role, and by reasonably setting the size of these gaps, the bending degree and bending angle of the pull wire 4 during bending can be controlled.

[0045] Specifically, the fixed groove 65 is provided with multiple groups and is distributed on the sliding groove 63, and after bending, one side of the limiting rod 62 abuts against the limiting block 7 for limiting.

[0046] In this embodiment, the multiple groups of fixed grooves 65 are evenly or regularly distributed on the sliding groove 63, so that more precise control can be achieved when adjusting the bending degree. The distance between the fixed grooves 65 can be used as the smallest unit of bending adjustment, and the operator can select appropriate fixed grooves 65 to fix the limiting rod 62 according to the specific bending requirement, to achieve adjustment of the bending degree.

[0047] In use, the pull wire 4 is placed between the rotating ring 5 and the fixed block 6, the bending handle 8 is rotated through the rotating bearing rotating pulley 2, the pull wire 4 can be bent, the sliding block 52 can slide on the sliding rail 51, the screw 53 can be adjusted, the screw 53 is fixed on the sliding rail 51 through the threaded hole 54, the screw 53 is removed, the rotating ring 5 is fixed on the sliding block 52, the sliding block 52 is slid to the appropriate position of the sliding rail 51, the screw 53 is fixed, the pull wire 4 is placed between the rotating ring 5 and the fixed block 6. The bending handle 8 is fixed on the rotating pulley 2 through the stud 9, the rotating pulley 2 can rotate around the fixed column 3, the bending handle 8 is pulled down, the pull wire 4 can be bent, the fixed block 6 is provided with a limiting rod 62, the fixed bolt one 61 and the fixed bolt two 64 are removed, the limiting rod 62 is moved to the angle at which the pull wire 4 needs to be bent, then the fixed groove 65 is fixed, the rotating pulley 2 is provided with a limiting block 7, when the bending handle 8 is bent to a certain angle, the limiting block 7 hits the limiting rod 62, the limiting and bending to the appropriate angle can be achieved.
