Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a novel copper drawing machine for cable manufacturing. Background Technology

[0002] In the cable manufacturing industry, the copper wire drawing machine is a core piece of equipment, and its performance directly affects the quality and production efficiency of cables. Traditional copper wire drawing machines mostly adopt single-point tension control or simple mechanical structures, which have many drawbacks in practical applications. On the one hand, single-point tension control is difficult to balance the force on the copper wire during the drawing process in real time, which can easily lead to problems such as diameter deviation, surface scratches, or even breakage of the cable, failing to meet the high precision and high stability requirements of high-end cables. On the other hand, the rotating roller is usually passively tractioned, and during long-distance drawing, the tension fluctuates significantly due to factors such as the cable's own weight and friction, which seriously restricts the continuity of production and the yield of finished products. In addition, the adjustment function of traditional equipment is limited, making it difficult to quickly adapt to the drawing process of copper wires of different specifications. Frequent adjustments are required when changing products, which is not only time-consuming and labor-intensive but also increases production costs. With the continuous improvement of the cable industry's requirements for product quality and production efficiency, a new type of copper wire drawing machine that can accurately control tension, stabilize traction, and flexibly adjust is needed to solve the technical bottlenecks of existing equipment. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] Therefore, the purpose of this utility model is to provide a new type of copper tensioning machine for cable manufacturing, which can solve the existing problems of uneven tension and unstable long-distance traction.

[0005] To solve the above-mentioned technical problems, this utility model provides a novel copper drawing machine for cable manufacturing, which adopts the following technical solution: it includes a base plate, and support rods are provided on the upper part of the base plate near both ends. A top plate is fixedly connected to the upper end of the support rods. A bracket is fixedly connected to the upper part of the top plate near the right end.

A large gear is meshed with the outer surface of the small gear. A spacing adjustment mechanism is provided on the upper part of the base plate, and a tension adjustment mechanism is provided on the inner side of the support rods.

[0006] The spacing adjustment mechanism includes a slide rail, a slider, an adjusting roller, and a guide wheel;

[0009] The above technical solution involves a limiting sleeve and a rotating component supporting the rotation of the rotating roller, reducing friction. The rotating roller is linked to the drive motor via a large gear to achieve active traction, thus offsetting the tension loss caused by the weight of the copper wire and friction.

[0010] Optionally, the lower end of the slide rail is located in the middle of the base plate, and the inner wall of the slide rail is slidably connected to the slider.

[0011] The above technical solution, namely the sliding connection between the slider and the slide rail, provides a mechanical basis for adjusting the guide wheel spacing, ensuring a smooth adjustment process.

[0012] Optionally, a first drive motor is fixedly connected to the left end of the slide rail, and a positive and negative threaded rod is fixedly connected to the output end of the first drive motor. The outer surface of the positive and negative threaded rod is threadedly connected to the slider.

[0013] The above technical solution involves a first drive motor that drives a slider to move via a forward and reverse threaded screw, achieving precise control of the guide wheel spacing. The forward and reverse threaded screws allow the two sliders to move synchronously in opposite directions, ensuring adjustment accuracy and adapting to the tension requirements of copper wires of different specifications.

[0014] Optionally, there are two sliders arranged horizontally, and an adjusting roller is fixedly connected to the upper end of each slider. The outer surface of the adjusting roller is rotatably connected to a guide wheel. There are two adjusting rollers and two guide wheels, each corresponding to one slider.

[0015] The above technical solution involves two horizontally distributed sliders, each connected to an adjusting roller and a guide wheel, forming a dual-point tension control structure.

[0016] Optionally, the inner side of the support rod is fixedly connected to the limiting rod, the inner side of the limiting rod is provided with a vertical sliding groove, the outer side of the limiting rod is provided with a horizontal limiting hole, the rear end of the limiting hole is connected to the sliding groove, and the inner wall of the sliding groove and the limiting hole is slidably connected to the limiting component.

[0017] Through the above technical solution, the vertical groove and horizontal limiting hole of the limiting rod provide a path for the movement and fixation of the limiting component, allowing the operator to adjust the height of the tensioning roller according to the specifications of the copper wire.

[0018] Optionally, the mounting bracket has grooves on both sides, a spring is fixedly connected to the bottom of the groove, the front end of the spring is fixedly connected to the limiting block, and the front end of the limiting block is fixedly connected to the limiting member.

[0019] Through the above technical solution: the groove of the mounting bracket, the spring and the limiting block form an elastic buffer structure, and the preload of the spring provides additional tension support for the copper wire.

[0020] Optionally, a tension roller is rotatably connected to the inner side of the mounting bracket.

[0021] The above technical solution involves installing a tension roller inside the mounting frame. Through height adjustment and elastic support, it provides auxiliary tension force on the path of the copper wire from the rotating roller to the outlet hole. Working in conjunction with the double guide wheels and the rotating roller, it further ensures tension uniformity and guarantees the quality of the finished cable.

[0022] In summary, this utility model has at least one of the following beneficial effects:

[0023] 1. Through dual-point tension control with dual guide wheels, the copper wire tension is monitored and dynamically adjusted in real time, effectively avoiding defects such as cable diameter deviation and surface scratches caused by uneven tension, improving cable roundness and surface smoothness.

[0024] 2. The tension adjustment, spacing adjustment and tensioning auxiliary mechanism of the equipment can be flexibly adjusted, and it is compatible with copper wire drawing processes of different diameters and materials. Production tasks can be quickly switched without replacing core components, effectively reducing the company's equipment procurement costs and improving equipment utilization.

[0034] The spacing adjustment mechanism includes a slide rail 4, a slider 7, an adjusting roller 8, and a guide wheel 9. The lower end of the slide rail 4 is located in the middle of the base plate 1. The inner wall of the slide rail 4 is slidably connected to the slider 7. The left end of the slide rail 4 is fixedly connected to a first drive motor 5. The output end of the first drive motor 5 is fixedly connected to a positive and negative threaded rod 6. The outer surface of the positive and negative threaded rod 6 is threadedly connected to the slider 7. There are two sliders 7, which are horizontally distributed. The upper end of the slider 7 is fixedly connected to an adjusting roller 8. The outer surface of the adjusting roller 8 is rotatably connected to the guide wheel 9. There are two adjusting rollers 8 and two guide wheels 9, which correspond one-to-one with the sliders 7.

[0035] The tension adjustment mechanism includes a limiting rod 18, a mounting frame 22, a limiting component 25, and a limiting block 10. The inner side of the support rod 2 is fixedly connected to the limiting rod 18. A vertical sliding groove 19 is provided on the inner side of the limiting rod 18, and a horizontal limiting hole 20 is provided on the outer side of the limiting rod 18. The rear end of the limiting hole 20 communicates with the sliding groove 19. The inner wall of the sliding groove 19 and the limiting hole 20 are slidably connected to the limiting component 25. Grooves 21 are provided on both sides of the mounting frame 22. A spring 23 is fixedly connected to the bottom of the groove 21. The front end of the spring 23 is fixedly connected to the limiting block 10. The front end of the limiting block 10 is fixedly connected to the limiting component 25. A tensioning roller 24 is rotatably connected to the inner side of the mounting frame 22.

[0036] Working principle: When this new type of copper wire drawing machine for cable manufacturing is working, the copper wire is first introduced from outside the equipment and spirally wound on two guide wheels 9 to form an initial guiding path. The two guide wheels 9 not only undertake the function of guiding the cable, but also form a dual-point tension control core through innovative design. Each guide wheel 9 is connected to an independent spacing adjustment mechanism. The spacing is precisely controlled by the first drive motor 5 driving the positive and negative threaded rods 6. The guide wheels 9 have built-in torque sensors to monitor the cable tension in real time. When the copper wire is wound on the guide wheels 9, the two guide wheels form front and rear tension control points. The front guide wheel 9 applies pretension to the copper wire that has just entered the equipment, while the rear guide wheel 9 dynamically fine-tunes the tension according to the torque feedback to ensure that the cable is subjected to uniform force before entering the rotating roller 11.

[0037] The rotating roller 11 is fixedly connected to the large gear 15. The second drive motor 14 drives the small gear 16 and the large gear 15 to rotate, so as to achieve rotation in the same direction as the winding direction of the copper wire and actively assist traction. The surface of the rotating roller 11 is designed with anti-slip texture, which works with the double guide wheels to maintain the stability of tension over long distances. When the copper wire is spirally wound by the rotating roller 11 and extends out from another through hole on the top plate 3, the active traction of the rotating roller 11 can offset the tension loss caused by the weight of the cable and friction, ensuring that the tension fluctuation of the cable is controlled within a very small range during long-distance drawing.

[0038] In addition, the equipment is equipped with a tensioning auxiliary mechanism to enhance tension control. An adjustable tensioning roller 24 is set on the path from the rotating roller 11 to the wire outlet hole. Its height is pre-adjusted by a mechanical structure consisting of a limiting member 25, a limiting rod 18, and a spring 23. According to the specifications of the copper wire, the operator adjusts the height by pressing the limiting member 25 along the slide groove 19 of the limiting rod 18, and then pushes it into the limiting hole 20 to fix it. The pre-tensioning force of the spring 23 provides additional tension support for the cable, further enhancing the stability of the system. Through the real-time tension control of the dual guide wheels, the active unidirectional traction of the rotating roller, and the synergistic effect of the tensioning auxiliary mechanism, this copper wire drawing machine can significantly improve the tension uniformity during the copper wire stretching process, effectively reduce problems such as cable deformation and surface scratches caused by tension fluctuations, and ensure the high precision and consistency of the finished cable.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
