Description

Technical Field

[0001] The utility model relates to the technical field of tungsten wire processing equipment, in particular to a device for adjusting the height and controlling the temperature of a small ten-mode die. Background Art

[0002] In the highly specialized field of tungsten wire processing, due to the limitations of temperature control and die height adjustment in the traditional small ten-mode die carrier system, it is difficult to meet the current production requirements of high precision and high efficiency. Specifically, traditional die carriers generally rely on a single centralized heating tube to regulate the temperature of the entire die carrier area. This method not only fails to achieve precise independent control of the temperature between dies but also results in uneven temperature distribution, affecting the physical properties of tungsten wire during the wire drawing process, including its microstructure, tensile strength, and dimensional stability, thereby limiting the further improvement of product quality.

[0003] In addition, the height design of traditional dies is often fixed, ignoring the thermal expansion characteristics and stress changes of metal materials in a high-temperature working environment. When the die carrier is heated, different parts will deform in different directions due to material and structural differences. If the die height cannot be adjusted flexibly, these deformations cannot be effectively compensated, resulting in an angle between the tungsten wire and the die, seriously affecting the drawing quality of the tungsten wire, including but not limited to tensile strength, diameter uniformity, and stability, thereby shortening the service life of the die, increasing production costs, and significantly reducing the yield rate.

[0039] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and implementation examples. 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.

[0040] It should be noted that when an element is referred to as "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. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are only for the purpose of illustration.

[0041] In the high-precision field of tungsten wire processing, due to the limitations of temperature control and die adjustment mechanisms, the traditional small ten-die die set system faces performance bottlenecks. Its centralized temperature control strategy cannot meet the requirement of accurately and independently regulating the temperature of each die area, resulting in uneven temperature distribution, damaging the physical properties of tungsten wire such as microstructure, tensile strength and dimensional consistency, and restricting the leap of product quality. At the same time, the fixed design of the die height does not consider the thermal collision effect of materials at high temperatures, making it difficult to compensate for the thermal deformation of the die set by height adjustment after heating, resulting in poor contact between the tungsten wire and the die parts, seriously affecting the drawing quality, such as the decrease of strength, diameter uniformity and stability, shortening the die life, pushing up the production cost, and significantly reducing the production yield.

[0042] To solve the above problems, please refer to Figures 1 to 6 , an embodiment of the present utility model provides a small ten-die die height adjustable and temperature controllable device for tungsten wire 40 drawing process, including:

[0043] A die set support 10, as the basic support structure of the whole device, ensures the overall stability and load-bearing capacity.

[0044] A die carrier 20, installed on the die set support 10. A plurality of polycrystalline dies 30 are adjustably installed on the die carrier 20. The plurality of polycrystalline dies 30 are arranged at intervals in parallel. The polycrystalline dies 30 are used to clamp the tungsten wire 40. The arrangement at intervals in parallel effectively optimizes the space utilization, and at the same time ensures that each tungsten wire 40 can be accurately clamped, ensuring the uniformity of the tungsten wire 40 drawing process. A corresponding heating tube 50 is provided beside each tungsten wire 40. The heating tube 50 is installed through the die carrier 20 to realize precise heating of the environment around the tungsten wire 40, promoting the plasticity and drawing efficiency of the tungsten wire 40. A corresponding thermocouple 60 is also provided beside each heating tube 50. The thermocouple 60 is used to feedback the heating temperature of the heating tube 50, ensuring the accuracy and real-time nature of temperature control, and guaranteeing the stability of the drawing process parameters.

[0045] An adjusting member 70, adjustably installed on the die set support 10, is used to adjust the installation height of the polycrystalline die 30, improving the adaptability and flexibility of the equipment, so as to effectively compensate for the deformation of the die caused by the thermal expansion characteristics and stress changes of the metal material in the high-temperature working environment, avoiding a large angle between the tungsten wire 40 and the die, so as not to seriously affect the drawing quality of the tungsten wire 40, thereby improving the die service life, reducing the cost, and increasing the yield.

[0046] The graphite ash box 80 is detachably installed on the side of the die carrier bracket 10 away from the die holder 20. The graphite ash box 80 is used to collect the graphite ash generated during the drawing of the tungsten wire 40. The detachable design facilitates the treatment and recycling of the graphite ash and keeps the working environment clean.

[0047] The die carrier cover 90 is adjustably installed on the side of the die holder 20 away from the die carrier bracket 10. It not only protects the internal components from external interference but also plays a role in heat insulation, and provides the possibility of further adjusting and optimizing the drawing space, ensuring the sealing and safety of the drawing process.

[0048] In this embodiment, the heating tubes 50 are installed through both sides of the die holder 20 and are located directly below the tungsten wire 40, effectively realizing the uniform radiation and conduction of heat, ensuring the consistency of the heated temperature. The multiple heating tubes 50 are arranged in parallel at intervals, further optimizing the heat distribution, avoiding local overheating, and improving the accuracy of temperature control. The polycrystalline die 30 is arranged between every two heating tubes 50 on the same side of the die holder 20. Such a layout not only optimizes the spatial layout of the device, protects the polycrystalline die 30 from direct high-temperature impact, but also promotes the indirect and uniform transfer of heat to the inside of the die, ensuring the forming quality of the product. The thermocouple 60 is installed through both sides of the die holder 20 and is located directly below the heating tubes 50. This design accurately monitors the real-time temperature of the working area of the die, provides an accurate basis for the feedback adjustment of temperature control, realizes the closed-loop control of temperature, and ensures the constancy and predictability of the working temperature of the device.

[0049] The die carrier 20 includes an installation core 21 and a frame body 22. The installation core 21 and the frame body 22 work together to ensure the stability of the structure and the efficient realization of functions. A first installation cavity 221 is provided on the frame body 22, and the installation core 21 is installed on the first installation cavity 221. The design of the first installation cavity 221 provides an accurate installation position for the installation core 21, ensuring the stability of the structural connection. An installation groove 211 corresponding to the polycrystalline die 30 is provided at one end of the installation core 21 away from the die holder bracket 10, ensuring the stability and alignment accuracy of the installation of the polycrystalline die 30. The polycrystalline die 30 is installed on the installation groove 211 through an installation block 31, realizing fast, convenient installation, replacement and maintenance operations. An avoidance groove 212 corresponding to the tungsten wire 40 is also provided on the installation core 21, and avoidance notches 222 corresponding to the avoidance groove 212 are provided on both sides of the frame body 22. The design of the avoidance groove 212 and the avoidance notches 222 not only provides sufficient space for the drawing of the tungsten wire 40, but also optimizes the heat transfer path, reducing the non-uniformity caused by heat loss. One end of the adjusting member 70 sequentially passes through the die holder bracket 10, the frame body 22, the installation core 21 and the installation block 31, and abuts against the polycrystalline die 30. The design of the adjusting member 70 allows the operator to finely adjust the polycrystalline die 30, ensuring the precise control of the die height and improving the forming accuracy of the product. A dust leakage through groove 215 is also provided on the installation core 21. The dust leakage through groove 215 is located on one side of the installation groove 211 and communicates with the installation groove 211. First dust leakage through holes 224 and second dust leakage through holes 11 corresponding to the dust leakage through groove 215 are respectively provided on the frame body 22 and the die holder bracket 10, effectively removing the graphite dust generated during the drawing of the tungsten wire 40, ensuring the normal progress of the drawing process and prolonging the service life of the device. First installation holes 213 and second installation holes 214 corresponding to the heating tube 50 and the thermocouple 60 are respectively provided on the installation core 21, and first avoidance holes 225 and second avoidance holes 226 corresponding to the heating tube 50 and the thermocouple 60 are respectively provided on the frame body 22. The heating tube 50 passes through the first avoidance hole 225 and is installed on the first installation hole 213, and the thermocouple 60 passes through the second avoidance hole 226 and is installed on the second installation hole 214.

[0050] Here, the precise correspondence between the first installation holes 213, the second installation holes 214 and the first avoidance holes 225, the second avoidance holes 226 provides convenience for the installation of the heating tube 50 and the thermocouple 60, ensuring the precise positioning and efficient operation of the temperature control elements.

[0051] Furthermore, a third mounting hole 12 is provided on the mold frame support 10, and the third mounting hole 12 is located beside the second ash leakage through hole 11. This design further optimizes the overall structural layout of the device, and at the same time provides a positioning point for the installation of the adjustment member 70 to ensure the accuracy of the installation. A first avoidance notch 223 corresponding to the adjustment member 70 is also provided on the frame body 22, and the first avoidance notch 223 is located on one side of the first ash leakage through hole 224 and is connected to the first ash leakage through hole 224, which not only facilitates the smooth passage of the adjustment member 70, but also promotes the internal structure of the device. The circulation of airflow is helpful for the discharge of graphite ash. A second avoidance slot 312 corresponding to the adjusting member 70 is also provided on the mounting block 31 to accurately correspond to the adjusting member 70 to ensure smooth and unobstructed adjustment. At the same time, the supporting and fixing effect of the mounting block 31 on the polycrystal mold 30 is enhanced. The adjusting member 70 passes through the third mounting hole 12, the first avoidance slot 223 and the second avoidance slot 312 in sequence, and is in contact with the polycrystal mold 30, thereby achieving fine-tuning and precise control of the height of the polycrystal mold 30 and ensuring the consistency and stability of the product quality.

[0052] An arc-shaped placement groove 311 is formed at one end of the mounting block 31 away from the frame body 22 , and the polycrystalline mold 30 is mounted on the arc-shaped placement groove 311 .

[0053] The design of the arc-shaped placement groove 311 fully considers the shape characteristics of the polycrystal mold 30, ensures that the polycrystal mold 30 can be stably and accurately installed on the arc-shaped placement groove 311, reduces the position error and additional installation friction during the installation process, and prolongs the service life of the polycrystal mold 30. At the same time, the arc-shaped placement groove 311 also optimizes the internal stress distribution of the polycrystal mold 30, improves the overall strength and stability of the polycrystal mold 30, and provides a solid guarantee for the efficient operation of the tungsten wire 40 drawing process.

[0054] The mold frame cover 90 includes a cover body 91 and an insulating block 92. A second installation cavity 94 is opened on the side of the cover body 91 close to the mold support 20. The insulating block 92 is installed on the second installation cavity 94. The second installation cavity 94 provides precise positioning and stable support for the installation of the insulating block 92. The insulating block 92 effectively isolates the influence of the external environment on the internal temperature of the device, ensuring the temperature stability and accuracy of the device in a complex working environment. The cover body 91 and the insulating block 92 are fixedly connected by a first fastener. This connection method not only enhances the overall strength of the mold frame cover 90, but also further improves the sealing performance of the device.

[0055] An operating handle 93 is also provided on one side of the mold frame cover 90, which facilitates the operator to open and close the mold frame cover 90. The connecting end of the operating handle 93 passes through the cover body 91 and is fixedly connected to the insulation block 92, ensuring the stability and reliability of the operating handle 93 during use.

At the same time, the addition of the handle 93 further enhances the overall structural strength of the mold base cover 90, providing additional guarantee for the stable operation of the device in high-temperature and high-pressure environments.

[0057] Furthermore, insertion slots 13 are provided on the mold frame. Opposite sides of the graphite ash box 80 are convexly provided with insertion strips 82. The graphite ash box 80 is installed on the insertion slots 13 through the insertion strips 82, achieving stable and convenient installation and improving the integration of the device.

[0058] Through the tight fit between the insertion strips 82 and the insertion slots 13, the graphite ash box 80 is firmly installed on the mold frame, effectively preventing loosening or falling off caused by vibration or temperature changes, and ensuring the stability and safety of the device operation. At the same time, this plug-in design also facilitates the maintenance and replacement of the graphite ash box 80, improving the maintenance efficiency and service life of the device.
