Description

Technical Field

[0001] This utility model relates to the field of copper wire annealing technology, specifically to an annealing device for drawing thin copper wires. Background Technology

[0002] Currently, annealing is necessary in the production of copper wire primarily to eliminate internal stress caused by work hardening and restore the material's ductility and conductivity. After stretching, copper wire increases in hardness and strength but decreases in plasticity, making it prone to breakage. Annealing, through heating to an appropriate temperature and then slowly cooling, allows the grains to rearrange, eliminates residual stress, and refines the grains, thereby improving the copper wire's flexibility, fatigue resistance, and conductivity. This ensures that it is less prone to cracking during subsequent processing or use, meeting the high reliability requirements of fields such as power transmission and electronic devices.

[0003] In existing copper wire annealing equipment, the copper wire is first heated above the critical temperature to induce austenitization within the material. It is then held at the heating temperature for a sufficient time to ensure uniform temperature throughout the material and to complete phase transformation or component diffusion. Finally, it is slowly cooled to bring the material closer to pearlite, thereby reducing hardness and improving plasticity. However, when cooling the copper wire with coolant, the coolant is in a fixed container. Prolonged cooling can easily cause the coolant temperature to rise, affecting the subsequent annealing effect. Utility Model Content

[0004] The purpose of this invention is to provide an annealing device for drawing thin copper wires to solve the problems described in the background art.

[0005] The technical solution of this utility model is implemented as follows:

A liquid storage tank is provided on its side, and the top surface of the liquid storage tank is connected to the top surface of the processing tank. A first pipe is provided on the bottom surface and connected to the cooling tank. A one-way valve is provided in the liquid tank and connected to the first pipe.

A third pipe is provided at the output end of the drive pump and connected to the top surface of the cooling tank. The cooling tank contains coolant for cooling the copper wire.

[0010] A further technical solution is that the cooling box is equipped with multiple rollers, which are used to connect the copper wires.

[0011] A further technical solution is that a heat exchange component is provided on the top surface of the liquid storage tank, with the bottom end of the heat exchange component located inside the liquid storage tank and the top end extending through the top wall of the processing tank.

[0012] A further technical solution is that the heat exchange component includes a heat absorption end and a heat dissipation end.

The tension ring then slowly rotates, keeping the copper wire at a constant temperature within the insulation components of the processing chamber. Once the insulated portion of the copper wire passes through the insulation plate, it enters the cooling chamber for cooling, completing the annealing process. After prolonged use, a liquid circulation component is activated, introducing new coolant into the cooling chamber to combine with the old coolant and lower its temperature. As the circulation component continuously introduces liquid, it forces the old coolant into itself, creating a continuous cycle that prevents the liquid in the cooling chamber from overheating. This solves the technical problem of coolant temperature rising and affecting subsequent copper wire annealing if the copper wire is cooled in a fixed container for an extended period.

[0018] 2. A heat exchange component is used to cool the liquid in the storage tank, so that the liquid inside can be continuously replaced in the cooling tank, ensuring that the liquid in the cooling tank never gets overheated.

[0025] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0026] Example 1

[0027] See Figures 1 to 2This utility model provides an annealing device for drawing thin copper wire, including a heating furnace 1, an insulation pipe 2 at the output port of the heating furnace 1, and a processing box 3 at the other end of the insulation pipe 2. The insulation pipe 2 covers the input port of the processing box 3. An insulation plate 4 is provided inside the processing box 3. An insulation component is provided on one side of the insulation plate 4, and a cooling box 5 is provided on the other side of the insulation plate 4. A liquid circulation component is provided above the top surface of the cooling box 5. The input and output ends of the liquid circulation component are both connected to the cooling box 5. The processing box 3 has an output port for outputting copper wire 6. A tension ring 7 is provided on the side of the processing box 3 for winding the copper wire 6.

[0028] In this embodiment, according to GB / T 3953-2008 standard, the heating furnace 1 heats the copper wire 6. After reaching the critical temperature, the tension ring 7 pulls the copper wire 6, causing it to enter the heat preservation component inside the processing box 3. Inside the processing box 3, it passes through the heat insulation plate 4 and enters the cooling box 5 to complete the annealing. The tension ring 7 is a T1180 type for driving.

[0029] The processing box 3 is equipped with two wheels for adjusting the exit direction of the copper wire 6, facilitating the operation of the tension ring 7 and improving the smoothness of the copper wire 6's exit.

[0030] Specifically, firstly, a portion of the copper wire 6 is connected via a tension ring 7. Then, the copper wire 6 to be processed is heated to its critical temperature using a heating furnace 1. The tension ring 7 then slowly rotates, keeping the copper wire 6 at a constant temperature within the insulation component of the processing chamber 3. After the insulated portion of the copper wire 6 passes through the insulation plate 4, it enters the cooling chamber 5 for cooling, completing the annealing process. After prolonged use, a liquid circulation component is activated, introducing new coolant into the cooling chamber 5 to combine with the old coolant and lower the temperature. As the circulation component continuously introduces liquid, it forces the old coolant into itself, creating a continuous cycle that prevents the liquid in the cooling chamber 5 from overheating. This solves the technical problem that if the coolant in a fixed container is used to cool the copper wire 6 for an extended period, the coolant temperature can easily rise, affecting the subsequent annealing effect of the copper wire 6.

[0031] Preferably, the heat preservation component includes a first connecting frame 8 and a second connecting frame 9 that are symmetrical to each other. The top of the first connecting frame 8 is connected to the inner top surface of the processing box 3, and the second connecting frame 9 is connected to the inner bottom surface of the processing box 3. A heating strip 10 is provided on the opposite side of the first connecting frame 8 and the second connecting frame 9. Both the first connecting frame 8 and the second connecting frame 9 are provided with wires that are connected to an external power source. The wires are connected to the heating strip 10.

[0032] In this embodiment, the first connecting frame 8 and the second connecting frame 9 facilitate the installation of the heating strip 10. When the copper wire 6 passes through the corresponding heating strip 10, it can be maintained at the temperature output by the heating furnace 1, which facilitates subsequent high-quality cooling.

[0033] Furthermore, the heating strip 10 is provided with an insulating ceramic strip 11 on its exterior, and the insulating ceramic strip 11 is connected to the first connecting frame 8 or the second connecting frame 9.

[0034] In this embodiment, an insulating ceramic strip 11 is used to prevent the risk of electric shock.

[0035] Preferably, the liquid circulation assembly includes a drive pump 12, which is fixed to the top surface inside the processing tank 3. A storage tank 13 is provided on its side, with the top surface of the storage tank 13 connected to the top surface inside the processing tank 3. A first pipe 14 is provided on the bottom surface and connected to the cooling tank 5. A one-way valve 15 is provided inside the liquid tank and connected to the first pipe 14. The drive pump 12 is connected to the other side of the storage tank 13 through a second pipe 16. A third pipe 17 is provided at the output end of the drive pump 12 and connected to the top surface of the cooling tank 5. The cooling tank 5 contains coolant for cooling the copper wire 6.

[0036] In this embodiment, when the liquid temperature in the cooling tank 5 rises, the drive pump 12 is activated. Low-temperature liquid is drawn from the liquid tank and sequentially introduced into the cooling tank 5 through the second pipe 16 and the third pipe 17. This process consolidates the temperature of the liquid in the cooling tank 5, thus cooling it down. When excess liquid fills the cooling tank 5, it is transferred to the storage tank 13 through the first pipe 14, circulating alternately to consolidate the liquid temperature within the cooling tank 5. This ensures that the low-temperature liquid effectively cools the copper wire 6, improving the annealing effect.

[0037] After the liquid in the cooling tank 5 enters the storage tank 13 through the first pipe 14, its one-way valve 15 can prevent the liquid in the storage tank 13 from flowing back into the cooling tank 5.

[0038] Furthermore, the cooling box 5 is equipped with multiple rollers 18, which are used to connect copper wires 6.

[0039] In this embodiment, multiple rollers 18 are installed inside the cooling box 5 to extend the immersion length of the copper wire 6 and improve the annealing effect. This also facilitates the smooth pulling of the tension ring 7.

[0040] Preferably, a heat exchange component is provided on the top surface of the liquid storage tank 13, with the bottom end of the heat exchange component located inside the liquid storage tank 13 and the top end extending through the top wall of the processing tank 3.

[0041] In this embodiment, the old liquid in the cooling tank 5 enters the storage tank 13, and is cooled by the heat exchange component, so that it can be used for the next time as superheated liquid in the integrated cooling tank 5.

[0042] Furthermore, the heat exchange assembly includes a heat absorption end 19 and a heat dissipation end 20. The heat absorption end 19 is in contact with the liquid in the liquid storage tank 13, and the heat dissipation end 20 is embedded in the top wall of the processing tank 3. The top cover of the heat dissipation end 20 is provided with a heat absorption mechanism.

[0043] In this embodiment, the Peltier effect is utilized to cool the liquid in the liquid tank by the heat absorption end 19, while the heat dissipation end 20 absorbs heat from the heat absorption end 19 and dissipates the heat, thereby cooling the liquid in the storage tank 13 and making it convenient for use as superheated liquid in the next integrated cooling tank 5.

[0044] Example 2

[0045] Please refer to Figure 3 and Figure 4 As a further improvement to Embodiment 1, the heat absorption mechanism includes a first housing 21 and a second housing 22, with the second housing 22 connected to the top surface of the heat dissipation end 20 via a cover 24.

[0046] In this embodiment, the first housing 21 absorbs the heat dissipation end 20 through the cover 24, and then cools down through the first housing 21 to avoid generating a large amount of heat that could affect the normal work of the surrounding staff.

[0047] Preferably, the second housing 22 is equipped with a heat-absorbing fan 23, which is connected to an external power source. The first housing 21 is equipped with a mesh box 25, which contains multiple layered plates 26 for placing cooling media.

[0048] It should be noted that the cooling medium can be ice.

[0049] In this embodiment, the heat absorbed by the heat-absorbing fan 23 enters the second chamber 22. The mesh box 25 contains a cooling medium to consolidate the heat and prevent excessive heat from affecting the normal work of the surrounding staff. Multiple layered plates 26 divide the mesh box 25 into multiple layers, forming a uniform consolidation layer and improving the heat cooling effect.

[0050] Preferably, the mesh box 25 is provided with a notch 27 corresponding to the layered plate 26, and the notch 27 is used to insert the cooling medium.

[0051] In this embodiment, after the ice is used up, new cooling medium can be inserted through the notch 27 to ensure continuous cooling of the heat.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
