Description

Technical Field

[0001] This utility model relates to the technical field of wire pulling devices for cable production, and in particular to wire pulling devices used in cable production. Background Technology

[0002] In cable production, wire drawing devices are mainly used to automate the wire feeding, drawing, and traction processes, reducing manual operation and improving production efficiency and quality. In the wire and cable production process, the wire drawing device (or wire drawing equipment) is the core equipment for realizing the plastic deformation of metal wires. By gradually reducing the cross-sectional area of ​​the metal billet (such as copper or aluminum rods) through multiple die holes, the wire can obtain a precise diameter and circular cross-section, ensuring that the product meets the design specifications. During the stretching process, surface defects of raw materials (such as oxide layers and scratches) are eliminated, forming a smooth and uniform wire surface, which meets the requirements for insulation layer coating or direct use. The cold work hardening effect is used to improve the strength, hardness, and wear resistance of the wire, but the elongation needs to be restored through the annealing process to balance the performance.

[0003] However, while existing cable pulling devices can position the cables during production, they cannot compress the coiled cables tightly. During handling or use, the cables are prone to shifting, causing them to unwind, become knotted, or affect subsequent work. Furthermore, the lack of a guiding mechanism during the pulling process causes the cables to shift and scatter, impacting subsequent work efficiency. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5This utility model provides an embodiment of a wire pulling device for cable production, comprising a wire pulling roller 7, wire reels 6 on both sides of the wire pulling roller 7, and brackets 1 on both sides below the wire pulling roller 7. Each bracket 1 has an internal mounting groove 3, and drive components are installed at both ends of the mounting groove 3. Adjusting components are connected through the front and rear ends between the two brackets 1. An arc-shaped plate is fixedly connected to one side of each bracket 1, and a drive component is installed on one side of one of the arc-shaped plates. The output end of the drive component is connected to a rotating shaft 11 located on one side of the wire reel 6. Multiple positioning grooves 8 are formed on the surface of the wire pulling roller 7. The spiral openings are arranged on the outer surface of the wire pull roller 7, and the spiral positioning grooves 8 are used to limit the cable. A second spring 18 is provided on one side of the wire spool 6. There are four second springs 18 arranged in a ring array. A pressure plate 9 sleeved on the outside of the wire pull roller 7 is fixedly connected to one side of the four second springs 18. An extension plate 5 is fixedly connected to the front end of the two wire spools 6. A support rod 15 is connected through the inside of the extension plate 5. A mounting plate 17 is fixedly connected to the lower end face of the support rod 15. An elastic element is sleeved on the outside of the support rod 15. A first guide is provided inside the mounting plate 17. A second guide is provided inside the extension plate 5, located below the first guide.

[0023] The adjusting component includes an adjusting rod 4, through which two supports 1 slide. By adjusting the distance between the two supports 1, it is suitable for pull rollers 7 of different lengths. The driving component includes a rotating roller 2, with a movable shaft connected through the inside of the rotating roller 2. The two rotating rollers 2 are located at the front and rear ends of the wire spool 6, respectively, to assist the wire spool 6 in pulling and rotating. Both adjusting rods 4 pass through the two supports 1, and the distance between the two supports 1 is adjusted by sliding the two supports 1 outside the two adjusting rods 4. This adjustment is made according to the length of the pull roller 7 and is suitable for pull rollers 7 of different lengths. While the two wire spools 6 are rotating, the pulling efficiency of the pull roller 7 is improved by the auxiliary drive of the two rotating rollers 2.

[0024] The driving component includes a motor 10, the output end of which is connected to a rotating shaft 11. The motor 10 drives the rotating shaft 11 to rotate, and the rotation of the rotating shaft 11 drives the rotation of the wire-pulling roller 7. The elastic component includes a first spring 16, which is sleeved on the outside of the support rod 15 for buffering during the wire-pulling process. The first guide component includes a movable guide roller 13, and the second guide component includes a fixed guide roller 12. The outer surfaces of both the fixed guide roller 12 and the movable guide roller 13 are provided with arc-shaped grooves 14. The outer surface of the fixed guide roller 12 is sleeved with a rubber sleeve. The rubber sleeve is driven by the motor 10 to rotate the shaft 11. The rotation of the shaft 11 drives the rotation of the wire reel 6, which in turn drives the pull roller 7 to rotate. The spiral positioning groove 8 on its surface can limit the cable and improve the stability of the cable pulling. At the same time, the pressure plate 9 and the four second springs 18 work together to press the cable to ensure the stability of its winding and prevent loosening. During the pulling process, the arc groove 14 of the fixed guide roller 12 and the movable guide roller 13 are used to guide the cable.

[0025] During operation, the distance between the two supports 1 and the two adjusting rods 4 is adjusted by sliding the two supports 1 outside the two adjusting rods 4. The adjustment is made according to the length of the pull roller 7, which is suitable for pull rollers 7 of different lengths. While the two coils 6 are rotating, the rotation of the rotating shaft 11 is driven by the motor 10 through the auxiliary drive of the two rotating rollers 2. The rotation of the rotating shaft 11 drives the rotation of the coils 6, and the pull roller 7 is also driven to rotate. The spiral positioning groove 8 on its surface can limit the cable and improve the stability of the cable pulling. At the same time, the cable is pressed by the cooperation of the pressure plate 9 and the four second springs 18 to ensure the stability of its winding and prevent loosening. During the pulling process, the arc groove 14 of the fixed guide roller 12 and the movable guide roller 13 is used to guide the cable.

[0026] Through the above steps, the spiral positioning groove 8 can achieve the positioning effect when the cable is wound. At the same time, the cooperation between the pressure plate 9 and the second spring 18 can fix the cable, prevent the cable from loosening and falling off, and improve stability. This solves the problem that the existing cable pulling device required in the production process can position the cable, but it cannot press the wound cable tightly. During handling or use, it is very easy for the cable to move around, causing the cable to unwind or get knotted. Moreover, there is no guiding mechanism in the pulling process, which causes the cable to deviate and scatter during the pulling process, affecting the efficiency of subsequent work.
