Description
Technical Field
[0001] This utility model relates to the field of high-efficiency copper wire drawing technology, and in particular to a high-efficiency copper wire drawing device. Background Technology
[0002] Copper wire, a fundamental material in industries such as power, electronics, communications, and construction, directly impacts the performance of downstream products. Wire drawing is one of the most critical processes in copper wire production, aiming to stretch the copper wire to the required specifications using dies. However, traditional wire drawing equipment faces numerous technical bottlenecks and challenges in actual production: During high-speed wire drawing, intense friction and impact occur between the copper wire and the die and positioning components, causing high-frequency vibration of the equipment. This vibration not only leads to uneven diameter of the drawn copper wire and scratches or wavy patterns on the surface, seriously affecting product quality, but also accelerates the wear of key equipment components (such as dies, bearings, and transmission mechanisms), shortening the equipment's lifespan. The copper wire needs to maintain stable and appropriate tension during the drawing process. Traditional equipment has relatively crude tension control; when the tension is too high, the copper wire is easily broken, causing production interruptions and material waste; when the tension is too low, the copper wire is prone to vibration, similarly affecting processing accuracy. Furthermore, rigid pressure mechanisms may cause indentations or damage to the copper wire surface during tension fluctuations; the wire drawing positioning block lacks effective buffering and limiting during high-speed reciprocating motion or sudden force changes. This can cause the positioning block to generate a rigid impact at the end of its stroke, producing a lot of noise and causing cumulative damage to the transmission system and frame, reducing the operational stability and reliability of the equipment; If the roller mechanism used to press the copper wire has insufficient rigidity in its installation structure, it is prone to swaying or shaking when subjected to force, which cannot guarantee the application of uniform and stable pressure to the copper wire, thus affecting the consistency of the wire drawing effect.
[0003] To address the above problems, it is necessary to design a high-efficiency copper wire drawing device to overcome them. Summary of the Invention

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] like Figures 1-4 As shown, a high-efficiency copper wire drawing device includes a workbench 1, a first fixed base 2, and a second fixed base 3. A positioning frame 4 is installed at one end of the first fixed base 2 and the second fixed base 3. A pull rod 5 is connected to one end of the inner side of the positioning frame 4 through a movable shaft. A positioning cylinder 6 is connected to the end of the inner side of the positioning frame 4 away from the pull rod 5 through a movable shaft. A positioning rod 7 is connected to the end of the positioning cylinder 6 away from the positioning frame 4. A positioning block 8 is connected to the end of the positioning rod 7 away from the positioning cylinder 6. A reinforcing block 9 is connected to the end of the positioning block 8 away from the positioning rod 7. A support plate 10 is installed on the inner side of the reinforcing block 9. A first telescopic rod 11 is connected to the inner side of the support plate 10. A spring 12 is installed on the outer wall of the first telescopic rod 11. An elastic rod 13 is installed at the end of the two support plates 10 near the first telescopic rod 11. A wire drawing positioning block 14 is connected to the end of the elastic rod 13 away from the support plate 10. The first fixed seat 2 and the second fixed seat 3 are both threadedly fixed to the positioning frame 4. The positioning frame 4 is rotatably connected to the pull rod 5 and the positioning cylinder 6 respectively through the movable shaft. The positioning cylinder 6 is rotatably connected to the positioning rod 7. The positioning rod 7 is rotatably connected to the positioning block 8. The positioning block 8 is fixedly connected to the reinforcing block 9. The reinforcing block 9 is fixedly connected to the support plate 10. The support plate 10 is rotatably connected to multiple first telescopic rods 11. The support plate 10 is rotatably connected to multiple elastic rods 13. The first telescopic rods 11 and the elastic rods 13 are both rotatably connected to the wire-drawing positioning block 14. The elastic rods 13 are fixedly connected to the micro damper 15. Specifically, in this embodiment, at the ends of the first fixed seat 2 and the second fixed seat 3 that are close to each other, a positioning frame 4 is fixedly connected by bolt threads. The interior of the positioning frame 4 constitutes the core motion unit of this device. On the inner side of each positioning frame 4, one end is connected to a pull rod 5 via a movable shaft such as a pin or bearing. The other end of the pull rod 5 is connected to an external driving device, such as a crank-slider mechanism driven by a servo motor or a hydraulic cylinder, to provide power for reciprocating linear motion. On the other end of the inner side of the positioning frame 4, a positioning cylinder 6 is also connected via a movable shaft. The other end of the positioning cylinder 6 is rotatably connected to a positioning rod 7, and the other end of the positioning rod 7 is rotatably connected to a positioning block 8. The positioning block 8 is fixedly connected to a reinforcing block 9 by welding or high-strength bolts, and the reinforcing block 9 is fixedly connected to a support plate 10. This multi-stage rotating connection structure can smoothly transmit the linear motion of the pull rod 5 to the support plate 10. The inner side of the support plate 10 is equipped with a buffer and wire drawing actuator. Specifically, at least two parallel first telescopic rods 11 are rotatably connected to the support plate 10. Each first telescopic rod 11 is fitted with a spring 12. The other ends of the first telescopic rods 11 and springs 12 are connected and fixed to a wire drawing positioning block 14. Furthermore, to increase structural stability and vibration damping, an elastic rod 13 is connected between the support plate 10 and the wire drawing positioning block 14. The center of the wire drawing positioning block 14 has a through hole for clamping copper wire and housing a wire drawing die. During operation… When the pull rod 5 is driven outward, it pushes the support plate 10 and the wire drawing positioning block 14 on it outward through the transmission of the positioning cylinder 6, positioning rod 7, positioning block 8 and reinforcing block 9. When the wire drawing positioning block 14 approaches the end of the stroke, the first telescopic rod 11 is compressed and the spring 12 is compressed sharply, thereby achieving gentle limiting and buffering and avoiding rigid impact. In order to further suppress the high-frequency vibration during the wire drawing process, micro dampers 15 are also fixedly installed at both ends of the wire drawing positioning block 14 by bolts. The micro damper 15 can be a hydraulic damper or a viscous damper, which can effectively absorb the small vibration generated by the friction between the copper wire and the mold and ensure the smoothness of the wire drawing process.
[0018] Both ends of the wire drawing positioning block 14 are connected to miniature dampers 15. The end of the wire drawing positioning block 14 away from the elastic rod 13 is connected to a positioning plate 16. Mounting plates 17 are installed on the inner sides of the two positioning plates 16. A top plate 18 is installed on the top of the mounting plate 17. A second telescopic rod 19 is connected to the bottom of the top plate 18. A limit spring 20 is installed on the outer wall of the second telescopic rod 19. A rounded corner limit block 21 is installed at the bottom of the second telescopic rod 19. A limit frame 22 is installed at the bottom of the rounded corner limit block 21. A movable rod 24 is connected to the inner side of the limit frame 22. A support rod 23 is installed at the end of the limit frame 22 near the mounting plate 17. A universal ball 25 is connected to the outer wall of the movable rod 24. A balance bar 26 is connected to both ends of the universal ball 25. A limit block 27 is sleeved on the outer wall of the two balance bars 26 near the universal ball 25. A pressure roller 28 is connected to the end of the balance bar 26 away from the universal ball 25. Mounting plate 17 is fixedly connected to top plate 18. Top plate 18 is rotatably connected to second telescopic rod 19. Second telescopic rod 19 is rotatably connected to rounded corner limit block 21. Rounded corner limit block 21 is fixedly connected to limit frame 22. Limit frame 22 is rotatably connected to movable rod 24. Movable rod 24 is rotatably connected to universal ball 25. Limit frame 22 is rotatably connected to support rod 23. Movable rod 24 is fixedly connected to two balance rods 26. Two balance rods 26 are rotatably connected to limit block 27 and pressure roller 28 respectively. The outer wall of two pressure rollers 28 can contact the surface of copper wire. Specifically, in this embodiment, a positioning plate 16 is fixedly connected to the outer side of each of the two wire drawing positioning blocks 14. A vertical mounting plate 17 is fixedly installed between the two positioning plates 16, and a horizontal top plate 18 is fixedly connected to the top of the mounting plate 17. A second telescopic rod 19 is connected to the bottom center of the top plate 18 via a movable shaft. A limiting spring 20 is sleeved on the outside of the second telescopic rod 19. The top end of the limiting spring 20 abuts against the top plate 18, and the bottom end abuts against a rounded corner limiting block 21. The bottom of the second telescopic rod 19 is rotatably connected to the rounded corner limiting block 21. A limiting frame 22 is fixedly connected to the bottom of the rounded corner limiting block 21. The limiting frame 22 has a U-shaped or rectangular frame structure. In order to improve the stability of the entire pressing mechanism, the two sides of the limiting frame 22 are fixedly connected to the sides of the mounting plate 17 through support rods 23 to form a stable triangular support structure. Inside the limiting frame 22, there is a movable rod 24. The two ends of the movable rod 24 are rotatably connected to the inner wall of the limiting frame 22 through bearings. A universal ball 25 is fixedly installed in the middle of the movable rod 24. Two balance bars 26 are symmetrically connected to both sides of the universal ball 25. A limit block 27 is fitted in the middle of the balance bar 26 to limit its swing amplitude. The ends of the two balance bars 26 are rotatably connected to a pressure roller 28 through bearings. During operation, the limit spring 20, through the downward preload of the second telescopic rod 19 and the limit frame 22, keeps the two pressure rollers 28 pressed against the copper wire. When the tension of the copper wire changes, it will push up the pressure roller 28, which will then drive the second telescopic rod 19 to extend upward through the balance bar 26 and the movable rod 24, further compressing the limit spring 20. This flexible adaptive process can maintain effective pressure on the copper wire while preventing excessive pressure from damaging the copper wire. The design of the universal ball 25 and the balance bar 26 ensures that even if the force on both sides is uneven, the two rollers can maintain synchronization and balance.
[0019] It should be noted that this utility model is a high-efficiency copper wire drawing device. In use, the copper wire to be processed is first passed through the wire drawing positioning block 14 on one side, between the two pressure rollers 28, and the wire drawing positioning block 14 on the other side, and fixed on the take-up machine. The external drive device is started, and the pull rod 5 begins to reciprocate. Taking the first fixed seat 2 side as an example, when its pull rod 5 is pushed out, it drives the wire drawing positioning block 14 on that side to clamp the copper wire and pull it outward, completing one wire drawing action. At this time, the first telescopic rod 11 and the spring 12 buffer at the end of the stroke, and the micro damper 15 absorbs vibration throughout the entire process. At the same time, the pressure roller 28 adaptively presses the copper wire to ensure its stability. Subsequently, the pull rod 5 retracts, and the pull rod 5 on the second fixed seat 3 side is pushed out to perform the same wire drawing action. This alternating process enables continuous and efficient copper wire drawing. The micro-dampers 15, directly installed at both ends of the drawing positioning block 14, function in real time, rapidly absorbing and dissipating high-frequency vibration energy, much like a car's shock absorber. This ensures the drawing positioning block 14 remains extremely stable throughout the process, guaranteeing a uniform copper wire diameter and a smooth, flawless surface. Under the preload of the limiting springs 20, the two pressure rollers 28 consistently apply a stable downward pressure to the copper wire. When the copper wire pushes up the rollers due to tension fluctuations, the two balance rods 26, connected by the universal balls 25, adjust synchronously to ensure balanced pressure on both sides, preventing the copper wire from being pressed unevenly. If the tension of the copper wire increases instantaneously or a thick node appears, the copper wire will push up the pressure rollers 28 with greater force. At this time, the second telescopic rod 19 extends upwards, further compressing the limiting springs 20. This process is flexible and adaptive, allowing the rollers to "yield" instead of resisting with constant rigid force, thereby effectively preventing damage or even breakage of the copper wire surface due to excessive pressure, achieving excellent protective effect. The mounting plate 17 and the top plate 18 provide a sturdy mounting base for the second telescopic rod 19, and the support rod 23 firmly fixes the limiting frame 22, which bears the main pressure, to the mounting plate 17, forming a high-rigidity closed-loop structure.
