When the present invention is in use: first, the bending device of the present invention is composed of a bending seat 2 and a guide seat 1. The guide seat 1 is used to linearly guide and fix the cable and wire. A fixed wire clamp structure and a spring clamp structure are arranged on the guide seat 1, wherein the fixed wire clamp structure mainly fixes the cable to ensure that the front end of the cable can be bent smoothly under force. The fixed wire clamp structure uses the limit seat 4 as the main body, and can adjust the position of the clamping head 6 by rotating the adjusting screw 5 thereon, and the clamping head 6 is used to generate pressure from both sides to fix the cable and wire. The spring clamp structure mainly plays an auxiliary role in the fixed wire clamp structure. When fixing the cable, first place the cable in the middle of the spring clamp structure, and use the elastic force generated by the spring 8 to clamp multiple guide tubes 9 on the cable, which has the effect of preliminary fixing but can also be adjusted, so as to facilitate the final fixation using the fixed wire clamp structure. The bending of the cable and wire is carried out in the bending seat 2, and a center seat 10 is arranged in the middle of the bending seat 2, and a spring clamp structure is arranged on the center seat 10. A bending die structure with adjustable curvature is provided, and the working position of the bending die structure is always kept in a straight line with the center line of the guide seat 1 to ensure that it is just in contact with the side of the cable.

The polygonal bending die 17 is driven to rotate by the adjusting disk, and the cable can be bent and guided by the arc-shaped protrusions with different curvatures to adapt to cables and wires of different thicknesses. The adjusting disk is further divided into a lower adjusting disk 15 and an upper adjusting disk 16. The adjusting shaft 14 can be driven up and down by the first push rod 12, and the polygonal bending die 17 on the lower adjusting disk 15 or the upper adjusting disk 16 is used. Therefore, the present invention can perform bending work on cables and wires of different sizes, and there is no need to manually replace the bending die.

After the adjustment is completed, the lifting disk 19 is pushed up by the second push rod 18, and the positioning rod 20 is inserted into the positioning hole 21 to fix the two adjusting disks. The positioning rod 20 can strengthen the structure of the adjusting disk 16 to prevent the pressure generated when the cable is pressed on the polygonal bending mold 17 from acting on the adjusting shaft 14 to cause it to bend. After the fixing of the cable and the adjustment of the bending mold structure are completed, the bending of the cable and the wire is completed by applying pressure by the pressure rod 24. The central axis 22 drives the rotating rod 23 to rotate so that the pressure rod 24 rotates along the arc groove 25, which can generate pressure on the cable from the side, so that the cable is bent under the guidance of the arc-shaped protrusion of the polygonal bending mold 17. The pressure rod 24 of the present invention does not bend the cable at one time, but is intermittently performed in batches, so that the cable can be bent to 30°, 60° and 90° in turn. The cable and the wire have a certain amount of time to adapt to the bending angle, balance the extrusion force inside it, and prevent the cable from being damaged. 4 is controlled by the central axis 22, and the central axis 22 is driven by a driving structure with a driving angle that increases in sequence. The driving structure takes the back plate 30 as the center. The first rack 34, the second rack 35, and the third rack 36 with increasing lengths are installed on the back plate 30 through the first bottom plate 31, the second bottom plate 32, and the third bottom plate 33. The first rack 34, the second rack 35, and the third rack 36 can be used to mesh with the gear 38 in sequence, drive the gear 38 to rotate different angles, and then rotate the pressure rod 24 to different positions, and complete the bending of the cable and wire in three times. The first rack 34, the second rack 35, and the third rack 36 are meshed with the gear 38 in sequence through the lifting and lowering movement of the back plate 30. The driving screw 29 is used to drive the slide 28 to rise on the guide seat 27, and the back plate 30 is driven to rise, so that the first bottom plate 31, the second bottom plate 32, and the third bottom plate 33 are moved to a height horizontal to the gear 38 in sequence, and the batch driving of the pressure rod 24 is completed.
