It should be understood that the specific implementation examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0037] Currently, the heating technology of the large ten-mode furnace body generally relies on the S-shaped heating resistance wire as the heat source to heat multiple tungsten wires with different diameters in the furnace through a unified system. Although this solution basically meets the heating requirements, it faces challenges due to its design defects. A single S-shaped resistance wire is difficult to accurately control the temperature of each tungsten wire. Coupled with only relying on a single thermocouple for monitoring, it leads to uneven heating, affecting the heat treatment effect of the material and the quality of subsequent processing. The difference in the diameter of the tungsten wire exacerbates this problem, making it difficult to ensure the strength stability and consistency during the drawing process.

[0038] To solve the above problems, please refer to Figures 1 to 3 , the embodiment of the present utility model provides a separate temperature control device for the large ten-mode furnace body, which is used for the heating and drawing process of the tungsten wire 80, and includes:

[0039] Upper furnace chamber 10.

[0040] Lower furnace chamber 20, which is arranged below the upper furnace chamber 10. The lower furnace chamber 20 serves as the main heating cavity, realizes efficient heat retention and transfer through its structure, and cooperates with the upper furnace chamber 10 to play a key role in heat insulation and heat preservation.

[0041] Mounting frame 30, which is used to install and fix the lower furnace chamber 20 to ensure the stability and durability of the overall structure of the furnace body.

[0042] The installation platform 40 is arranged beside the lower furnace chamber 20, and the upper furnace chamber 10 is slidably installed on the installation platform 40 to ensure the smooth movement and precise positioning of the upper furnace chamber 10.

[0043] The heating bus 50 is installed in the lower furnace chamber 20. A plurality of first installation through grooves 221 arranged in parallel are formed on one side of the lower furnace chamber 20 close to the upper furnace chamber 10. Thermocouples 111 corresponding to the plurality of first installation through grooves 221 are also arranged on the upper furnace chamber 10. One end of the thermocouple 111 passes through the upper furnace chamber 10 and extends to the first installation through groove 221 to monitor and feedback the temperature data in the first installation through groove 221 in real time, providing a key basis for precise temperature control.

[0044] The heating wire 60 is arranged above the heating bus 50 and installed in the first installation through groove 221. The heating power is independently adjusted according to the feedback signal of the thermocouple 111 to ensure that each tungsten wire 80 can obtain uniform and precise heating effects. The tungsten wire 80, as the object to be heated, passes through the first installation through groove 221 and is placed above the heating wire 60. By precisely controlling the heating process, efficient heat treatment of tungsten wires 80 with different diameters is realized, ensuring uniform heating and the strength stability and consistency during the drawing process of the tungsten wire 80.

[0045] Here, the setting of the first installation through groove 221 not only provides a precise placement space for the heating wire 60 and the tungsten wire 80, but also optimizes the uniformity of heat distribution.

[0046] In this embodiment, linear guide rails 41 are arranged on both sides of the installation platform 40. An installation plate 42 is slidably installed on the linear guide rails 41. The upper furnace chamber 10 is installed on the installation plate 42 through a fixing frame 70, which not only ensures the structural stability, but also facilitates maintenance and replacement. Among them, the design of the linear guide rail 41 not only ensures the stable sliding of the installation plate 42, but also greatly improves the accuracy and smoothness of the temperature control device during the adjustment process. Through a flexible moving mechanism, precise control of the position of the upper furnace chamber 10 is realized. The upper furnace chamber 10 includes an upper shell 11 and an upper die furnace 12. A first accommodation cavity is formed on one side of the upper shell 11 close to the lower furnace chamber 20. The upper die furnace 12 is installed on the first accommodation cavity, ensuring the compactness and high efficiency of the furnace body structure. In particular, the thermocouple 111 is installed on the side of the upper shell 11 away from the lower furnace chamber 20, effectively avoiding direct high-temperature radiation and ensuring the accuracy and service life of the temperature measuring element. One end of the thermocouple 111 passes through the upper shell 11 and the upper die furnace 12 in sequence and extends to the first installation through groove 221. A first installation through hole 121 adapted to the thermocouple 111 is formed on the upper die furnace 12, which not only ensures the stable installation of the thermocouple 111, but also optimizes the heat transfer efficiency and further improves the temperature control accuracy.

[0047] On one side of the upper housing 11 away from the upper die furnace 12, there are convex mounting blocks 113. The mounting blocks 113 are arranged on both sides of the thermocouple 111. One end of the fixing frame 70 is connected to the mounting block 113, and the other end of the fixing frame 70 is connected to the mounting plate 42, ensuring the stability of the structural connection and enhancing the overall stability of the device. A first gasket 71 is also provided between the fixing frame 70 and the mounting block 113 to further improve the tightness and durability of the connection, ensuring the efficient and stable operation of the temperature control device.

[0048] An operating handle 112 is also provided between the two mounting blocks 113. This design further improves the operation convenience of the temperature control device, facilitating users to perform quick and effective control. The operating handle 112 is installed on the upper housing 11. Through the integrated design, the overall structure stability is enhanced, and at the same time, it is convenient to position and fix the operating handle 112. One end of the operating handle 112 passes through the upper housing 11 and is connected to the upper die furnace 12. This penetrating design ensures the direct linkage between the operating handle 112 and the upper die furnace 12, improving the operation response speed. An installation hole 122 corresponding to the operating handle 112 is also provided on the upper die furnace 12 to ensure the connection stability and avoid operation errors caused by structural looseness or deviation, thus ensuring the reliability and stability of the temperature control device in a complex working environment.

[0049] Further, on the side of the mounting plate 42 close to the mounting table 40, there is a fixed slider 43. The mounting plate 42 is installed on the linear guide 41 through the fixed slider 43, reducing the errors caused by looseness or friction, enabling the upper furnace chamber 10 installed on the mounting plate 42 to slide smoothly on the predetermined path, improving the stability and accuracy of the temperature control device during the adjustment and installation process, and also improving the installation efficiency of the tungsten wire 80. Limit blocks 44 are also provided at both ends of the mounting table 40 along the length direction of the linear guide 41. The limit blocks 44 are used to limit the sliding stroke of the mounting plate 42, ensuring the controllability and accuracy of the temperature control device during the opening and closing adjustment process, and avoiding equipment damage or performance degradation caused by excessive adjustment.

[0050] Both of the two limit blocks 44 are located between the two linear guides 41 and are installed on the mounting table 40. This design not only optimizes the space layout but also ensures that the limit blocks 44 can effectively limit the mounting plate 42 sliding on the linear guide 41, improving the overall structural stability and safety, and ensuring the stable operation and precise control of the temperature control device in a complex working environment.

[0051] The fixing frame 70 is in a "Z" shape, meeting the requirements of a compact structural space layout. Reinforcing ribs 72 are also provided on the fixing frame 70 to enhance the load-bearing capacity and bending resistance of the fixing frame 70, effectively resisting the deformation caused by environmental factors, ensuring the firm connection between the upper furnace chamber 10 and the mounting plate 42, and thus ensuring the accuracy and efficiency of the temperature control process.

[0052] Furthermore, the lower furnace chamber 20 includes a lower housing 21 and a lower die furnace 22. A second accommodation cavity is formed on one side of the lower housing 21 close to the upper furnace chamber 10. The lower die furnace 22 is installed on the second accommodation cavity. The provision of the second accommodation cavity provides a stable and precise installation position for the lower die furnace 22, ensuring a tight fit between the upper furnace chamber 10 and the lower furnace chamber 20. The heating bus 50 is installed on one side of the lower die furnace 22 close to the upper furnace chamber 10. A first installation through groove 221 is formed on one side of the lower die furnace 22 close to the upper furnace chamber 10. The first installation through groove 221 is located above the heating bus 50, enabling heat to be transferred quickly and evenly, thereby improving the temperature control efficiency. A sliding avoidance notch 212 corresponding to the upper furnace chamber 10 is formed on one side of the lower housing 21 close to the installation table 40, providing sufficient opening and closing avoidance space for the sliding of the upper furnace chamber 10 along with the installation plate 42, ensuring a tight fit between the upper furnace chamber 10 and the lower furnace chamber 20, and guaranteeing the smoothness and accuracy of the opening and closing process of the temperature control device. Avoidance slots 213 corresponding to the plurality of first installation through grooves 221 are also formed on the lower housing 21 to facilitate the threading and installation of the tungsten wire 80.

[0053] At both ends of the side of the lower die furnace 22 where the first installation through groove 221 is formed, pad installation grooves 222 are also formed. The pad installation grooves 222 and the sliding avoidance notch 212 are both arranged parallel to the first installation through groove 221. This parallel layout ensures the relative position stability among the components, avoiding performance degradation caused by misalignment or inclination. A second gasket 223 is installed in the pad installation grooves 222, which plays a buffering and supporting role, effectively reducing the friction and wear during the installation process of the upper furnace chamber 10 and the lower furnace chamber 20, extending the service life of the equipment, and ensuring the stability and reliability of the temperature control device during long-term operation.

[0054] An avoidance through hole 211 corresponding to the heating bus 50 is also formed on the lower housing 21, avoiding installation difficulties caused by space limitations.

[0055] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the principles of the present utility model shall be included within the protection scope of the present utility model.
