[0002] Tin-plated copper-clad steel wire, as a composite metal wire combining electrical conductivity and mechanical strength, is widely used in electronics, communications, and power industries. The core objective of its heat treatment process is to achieve metallurgical bonding between the plating and the base metal through precise temperature field control, thereby improving the wire's conductivity, corrosion resistance, and mechanical properties. However, the heat treatment of wire typically employs a single-sided heating mode, resulting in significant temperature differences between the upper and lower, and front and back areas of the furnace. This leads to inconsistent plating melting effects in different parts of the wire, easily causing quality problems. Utility Model Content

[0003] The purpose of this invention is to provide a heat treatment device for tin-plated copper-clad steel wire, which has the advantage of uniform heating.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device for tin-plated copper-clad steel wire, comprising a heating furnace, a circulating fan fixedly installed on the right side of the heating furnace, an exhaust pipe extending downwards from the outlet of the circulating fan into the interior of the heating furnace, an exhaust head connected to the top of the exhaust pipe, a spiral heating tube installed on the back of the inner cavity of the heating furnace, heat-conducting fins snapped onto the front of the spiral heating tube, a heater fixedly installed at the left end of the spiral heating tube extending to the outside of the heating furnace, an isolation plate installed at the center of the interior of the heating furnace, a drive motor fixedly installed at the bottom of the isolation plate, a rotating disk installed above the isolation plate through the output shaft of the drive motor, limit posts installed on both sides of the top of the rotating disk via connecting plates, and a vertical rod installed on the outer part between the two limit posts.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0020] Please see Figure 1 As shown, this utility model provides a heat treatment device for tin-plated copper-clad steel wire, including a heating furnace 1. A circulating fan 2 is fixedly installed on the right side of the heating furnace 1. The air outlet pipe of the circulating fan 2 extends downward into the interior of the heating furnace 1 and is connected to an exhaust pipe 3. An air outlet 4 is connected to the top of the exhaust pipe 3. A spiral heating tube 5 is installed on the back of the inner cavity of the heating furnace 1. A heat-conducting fin 7 is snapped onto the front of the spiral heating tube 5. A heater 6 is fixedly installed on the left end of the spiral heating tube 5 extending to the outside of the heating furnace 1. An isolation plate 9 is installed at the center inside the heating furnace 1. A drive motor 11 is fixedly installed at the bottom of the isolation plate 9. A rotating disk 12 is installed above the isolation plate 9 through the output shaft of the drive motor 11. Limiting posts 13 are installed on both sides of the top of the rotating disk 12 through connecting plates. A vertical rod 14 is installed on the outer part between the two limiting posts 13.

[0021] This technical solution uses a circulating fan 2 in conjunction with a spiral heating tube 5 and heat-conducting fins 7 to form a hot air circulation system, ensuring a uniform temperature field inside the furnace and avoiding local overheating of the wire. The rotating disk 12, the limiting column 13, and the vertical rod 14 constitute a rotating wire fixing mechanism, which can drive the wire to rotate at a uniform speed to ensure consistent heat treatment. The temperature detector 10 provides real-time feedback of temperature data, and combined with the adjustment of the ventilation opening and the sealing door 15, it achieves precise control of the heat treatment process. Example

[0022] Based on Embodiment 1, this utility model is as follows: Figure 2 As shown, a vent is provided on the top left side of the heating furnace 1, and guide rods 17 are installed on both sides of the vent. A sealing door 15 is slidably installed on the outside of the guide rods 17, and an adjustment knob 16 is locked to the end of the sealing door 15 and corresponding to the surface of the guide rods 17.

[0023] Adopting such Figure 1The technical solution shown allows for stepless adjustment of the opening and closing degree of the sealing door 15 via the guide rod 17 and the adjusting knob 16, precisely controlling the air intake of the vent. For the heat treatment requirements of different wire specifications, the ventilation volume can be dynamically adjusted to optimize the airflow field and temperature distribution inside the furnace. The sliding sealing door 15 can be fully opened without disassembly, facilitating quick cleaning of dust accumulation in the vent or cutting off the air supply during emergency shutdown. The adjusting knob 16 provides stable axial pressure to ensure that the sealing door 15 fits tightly against the edge of the vent, preventing hot gas leakage.

[0024] Secondly, in the technical solution, a bearing seat 8 is fixedly installed on both sides of the inner cavity of the heating furnace 1. The top of the bearing seat 8 is provided with a snap-fit ​​groove, and a snap-fit ​​block is installed inside the snap-fit ​​groove. The upper end of the snap-fit ​​block is connected to the bottom of the isolation plate 9. A positioning frame is fixedly installed on the left side of the inner cavity of the heating furnace 1, and a temperature detector 10 is snap-fitted inside the positioning frame. The temperature detector 10 is electrically connected to an external display screen.

[0025] Its adoption is as follows Figure 1 The technical solution shown allows for boltless and rapid installation of the isolation plate 9 by engaging with the snap-fit ​​slot of the bearing seat 8 via a snap-fit ​​block. The snap-fit ​​slot can be designed as a dovetail or T-slot structure to maintain axial positioning accuracy at high temperatures and prevent the isolation plate 9 from shifting due to thermal expansion. The temperature detector 10 is fixed by snap-fitting with a positioning frame, avoiding the risk of loosening under high-temperature vibration of traditional bolt connections and ensuring that the temperature probe is always in the optimal detection position. A ceramic insulating bushing can be embedded in the snap-fit ​​part to reduce the impact of heat conduction on the detector and extend its service life. Example

[0026] This utility model is as follows Figures 1-4 As shown, the bottom of the rotating disk 12 is embedded inside the partition plate 9. The partition plate 9 has partitions installed at equal intervals inside, and ventilation holes are provided between adjacent partitions. A furnace door is rotatably installed on the left side of the front of the heating furnace 1, and a buckle that matches the front slot of the heating furnace 1 is installed on the left side of the front of the furnace door.

[0027] Using the above technical solution, the bottom of the turntable 12 is embedded inside the isolation plate 9 to form a radial positioning constraint, reduce shaking during rotation, and ensure the stability of wire winding. The embedded design provides sufficient support rigidity while ensuring rotational flexibility.

[0028] The working principle of this utility model is as follows: The heater 6 is started, the spiral heating tube 5 begins to heat up, and the heat-conducting fins 7 evenly diffuse the heat into the interior of the heating furnace 1. Simultaneously, the circulating fan 2 is turned on, drawing air from the heating furnace 1 and blowing it back into the furnace through the exhaust pipe 3 and the air outlet 4, forming a hot air circulation that rapidly raises the furnace temperature to the set value. The furnace door is opened, and the tin-plated copper-clad steel wire is wound around the two limiting posts 13 and the vertical rod 14. The drive motor 11 is started, driving the rotating disk 12 to rotate at a uniform speed, thus making the wire rotate at a uniform speed. During rotation, the wire receives heat from the spiral heating tube 5 and the hot air circulation system in all directions and evenly, achieving uniform heat treatment. The temperature detector 10 monitors the temperature inside the heating furnace 1 in real time and transmits the data to an external display screen. The operator can adjust the air intake of the ventilation opening by adjusting the opening degree of the sealing door 15 according to the displayed temperature, thereby adjusting the furnace temperature. If the temperature is too high, the ventilation volume is increased to accelerate heat dissipation; if the temperature is insufficient, the ventilation volume is reduced to maintain heat.
