[0002] The high-uniformity annealing furnace for copper wire features a precise temperature control system paired with a uniform heat circulation device, minimizing temperature differences across different areas within the furnace. Parameters can be adjusted according to the specifications of the copper wire, efficiently removing internal stress and softening the material to ensure stable copper wire performance and consistent quality, thereby improving the yield rate of subsequent processing.

[0003] In existing copper wire annealing furnaces, copper wires are guided by a transmission structure into the preheating zone, constant temperature zone, and cooling zone in sequence to achieve the annealing effect.

This leads to uneven microstructure and properties of the annealed copper wire, severely affecting its elongation and product quality, and reducing the processing efficiency of the annealing furnace. Optimization and improvement are necessary to address these issues. Utility Model Content

[0020] Specifically, such as Figure 2 As shown, elastic guide rods 6 are slidably connected to both the front and rear ends of the movable plate 5. A connecting block 7 is fixedly connected to the bottom end of the elastic guide rod 6. An adjusting roller 8 is rotatably connected to the inner side of the connecting block 7. The movable plate 5 and the connecting block 7 are guided and connected by the elastic guide rod 6. A spring is connected to the outer side of the elastic guide rod 6. The spring is fixedly connected between the movable plate 5 and the connecting block 7 to adapt and control the tension during copper wire transmission.

[0021] Specifically, such as Figure 1 As shown, a guide roller 9 is fixedly connected to one side of the adjustment frame 3, and the guide roller 9 guides and transmits the copper wire after the tension is adjusted.

[0022] Specifically, such as Figure 3 As shown, a conduction hole 11 is provided inside the preheating box 10. A guide wheel 16 is provided at one end of the preheating box 10 near the bottom of the conduction hole 11. The guide wheel 16 is used to support and limit the transmission direction of the copper wire to ensure the stability of the transmission.

[0023] Specifically, such as Figure 3 As shown, a connecting plate 13 is fixedly installed at the top of the preheating box 10, and a telescopic rod 14 is fixedly installed on the inner side of the connecting plate 13. The hot pressing plate 15 is connected to the bottom telescopic end of the telescopic rod 14.

[0024] The constant temperature control component includes a constant temperature chamber 17, which is fixedly connected to the middle of the top of the support frame 1 near the preheating box 10. A diversion transmission pipe 20 is connected to the outside of the constant temperature chamber 17.

[0025] Specifically, such as Figure 4 As shown, the constant temperature chamber 17 has a conduction hole 18 inside. The top of the constant temperature chamber 17 is fixedly connected to an exhaust fan 19. The exhaust fan 19 draws air from the front and rear ends of the constant temperature chamber 17 through the exhaust hood 21. There is a certain temperature difference between the front and rear ends of the constant temperature chamber 17. The air is transmitted to the inside of the constant temperature chamber 17 through the diversion transmission pipe 20, which improves the uniformity of the internal temperature of the constant temperature chamber 17. Both ends of the exhaust fan 19 are connected to the exhaust hood 21.

[0026] In this embodiment: when the copper wire is annealed and preheated, an adjustable roller 8 is first set up in conjunction with a guide roller 9 to adjust the tension of the copper wire, ensuring the stability of the copper wire during transmission.

The temperature of the constant temperature chamber 17 is evenly agitated by the diversion transmission pipe 20 to improve the constant temperature maintenance effect.

[0027] Specifically, during the annealing process of the copper wire, the copper wire to be processed is first wound around the transfer roller 2, and then the copper wire rests on the top of the guide roller 9. The guide roller 9 and the hot press plate 15 are at the same horizontal position.

The top of the adjusting roller 8 is also elastically guided by the elastic guide rod 6, and the position is adjusted within a certain range to adapt to the transmission tension of the copper wire. Then, the copper wire is passed through the conduction hole 11 inside the preheating box 10. The outer ring of the conduction hole 11 is wound with a spiral heating ring 12, which can uniformly heat the wire. Before heating, the hot press plate 15 is brought close to the copper wire by the telescopic rod 14 to preheat it and improve the subsequent heating effect. Then, the copper wire is guided through the conduction hole 18 on the inside of the constant temperature box 17 and then kept warm by the temperature control structure inside the constant temperature box 17. At the same time, the exhaust fan 19 drives the exhaust hoods 21 on the front and rear sides of the constant temperature box 17 to exhaust air and distribute it evenly inside the constant temperature box 17 through the diversion transmission pipe 20 to improve the uniformity of heat preservation and further improve the annealing effect. Then, the copper wire passes through the cooling box 22 for cooling and is then wound on the take-up roller 24 for collection.
