[0033] The following combines the attached Figure 1-7 , and further elaborates on the present application.
[0034] The present application provides a high-efficiency annealing device for fine tungsten wire, adopting the following technical solutions:
[0035] Refer to Figure 1, The fine tungsten wire high-efficiency annealing equipment includes a frame 1, a wire feeding assembly 2, an inductive heating assembly 3, a measuring assembly 4, and a wire winding assembly 5. A control panel 11 is installed at the bottom of the frame 1. An MCU (Microcontroller Unit) is installed on the control panel 11 to control various electrical components on the equipment. A digital display screen is also installed on the control panel 11 to display information such as wire feeding speed, die temperature, and measured length. When annealing the fine tungsten wire 10 is required, the fine tungsten wire 10 passes from one end at the top of the frame 1 to the other end at the top of the frame 1. The wire feeding assembly 2, the inductive heating assembly 3, the measuring assembly 4, and the wire winding assembly 5 are sequentially arranged and installed along the threading direction of the fine tungsten wire 10 at the top of the frame 1.
[0036] Referring to Figure 1 and Figure 2 , the wire feeding assembly 2 includes a support base 21 and a loading tray 22. The support base 21 is installed at one end of the top surface of the frame 1. The loading tray 22 is rotatably installed on the side of the support base 21 through a rotating shaft. A tensioning wheel 221 is installed on the rotating shaft. The loading tray 22 is sleeved on the periphery of the tensioning wheel 221. The tensioning wheel 221 expands outwards and abuts against the inner ring of the loading tray 22 to fixedly clamp the loading tray 22, enabling the loading tray 22 to rotate with the tensioning wheel 221. The periphery of the loading tray 22 is wound with a coil of unannealed fine tungsten wire 10. During the annealing process, the fine tungsten wire 10 on the periphery of the loading tray 22 is passed from one end of the frame 1 to the other end of the frame 1.
[0037] Furthermore, referring to Figure 1 and Figure 2 , the wire feeding assembly 2 further includes a magnetic damper 23. The magnetic damper 23 is installed on the side of the support base 21 away from the loading tray 22. The magnetic damper 23 and the loading tray 22 are connected to the same rotating shaft through a coupling. When the loading tray 22 feeds wire, the magnetic damper 23 performs a slight braking on the loading tray 22 to compensate for the tension of the loading tray 22, so that during the process of rotating and feeding wire of the loading tray 22, the tension of the fine tungsten wire 10 is always kept constant, thereby making the wire feeding state of the fine tungsten wire 10 more straight, which is beneficial to improving the uniformity of the annealing process.
[0038] Referring to Figure 3 and Figure 4, the inductive heating component 3 includes a tungsten rod 31 and an induction coil 32. The tungsten rod 31 is fixedly installed on the frame 1. An annealing hole 311 is formed in the center of the tungsten rod 31. The diameter of the annealing hole 311 is the same as the wire diameter of the fine tungsten wire 10. The fine tungsten wire 10 passes through the annealing hole 311 and slides. The circumferential side of the fine tungsten wire 10 contacts the inner wall of the annealing hole 311. The induction coil 32 is evenly wound around the circumferential side of the tungsten rod 31. An alternating current with a high frequency (frequency range: 15 - 30 kHz) is passed through the electromagnetic induction coil. The tungsten rod 31 belongs to a metal rod. Eddy current heating will occur in the metal rod in a rapidly changing magnetic field. In this embodiment, eddy current heating occurs in the tungsten rod 31 in the strong magnetic flux with instantaneously changing polarity generated by the electromagnetic induction coil. The tungsten rod 31 conducts heat to the fine tungsten wire 10 in the annealing hole 311 through sliding contact, so that the fine tungsten wire 10 reaches the process temperature required for annealing. And when the current frequency and current magnitude remain unchanged, the tungsten rod 31 can maintain a constant process temperature, thereby making the annealing temperature of the fine tungsten wire 10 more stable, which is beneficial to making the processing quality of the fine tungsten wire 10 more uniform. In addition, compared with other metal rods, the tungsten rod 31 belongs to the same metal as the annealed fine tungsten wire 10, has the same melting point and hardness, and will not affect the quality of the fine tungsten wire 10 in the annealing process, thereby improving the annealing processing quality of the fine tungsten wire 10.
[0039] Refer to Figure 1 and Figure 3 , a heating machine 37 is installed on the side of the frame 1. Current modulation components such as a transformer and an inverter are installed in the heating machine 37. The induction coil 32 is connected to the heating machine 37, and the heating machine 37 is electrically connected to the control panel 11. The alternating current in the heating machine 37 is modulated by the MCU of the control panel 11 to change the magnitude of the alternating current passed through the induction coil 32, and the process temperature of the tungsten rod 31 can be adjusted. The maximum process temperature of the tungsten rod 31 can be adjusted up to 2500 °C, which is higher than the maximum temperature that a natural gas furnace can reach, and has a larger temperature control range, so as to meet the process requirements of the annealing temperature of more fine tungsten wires 10. At the same time, by changing the frequency of the alternating current passed through the induction coil 32, the heating rate of the tungsten rod 31 can be adjusted, and the preheating time for heating the fine tungsten wire 10 to the process temperature can be reduced, thereby improving the annealing efficiency of the fine tungsten wire 10.
[0040] Furthermore, refer to Figure 3, the inductive heating component 3 further includes a housing 33. The housing 33 covers the outside of the inductive coil 32. The internal space of the housing 33 is an inner cavity 331. The tungsten rod 31 passes through the inner cavity 331, and both ends of the tungsten rod 31 communicate with both side surfaces of the housing 33, so that the inductive coil 32 and the tungsten rod 31 are heated in a closed space, reducing the interference of external factors on the inductive coil 32 and reducing the temperature fluctuation of the tungsten rod 31, thereby improving the uniformity of the annealing temperature of the fine tungsten wire 10. In addition, a clamping cavity 332 is formed on the housing of the housing 33, and two circulation pipes 34 are fixedly connected to the housing of the housing 33. One circulation pipe 34 is used to introduce a coolant into the clamping cavity 332, and one circulation pipe 34 is used to discharge the coolant in the clamping cavity 332. The coolant in this embodiment is cold water. The coolant circulates in the housing 33, which can take away the heat on the housing 33, prevent the housing 33 from overheating, reduce the heat conduction of the housing 33 to other components, thereby protecting other components and improving the safety of the annealing process.
[0041] Furthermore, referring to Figure 3 , the inductive heating component 3 further includes a hydrogen pipe 35. The hydrogen pipe 35 communicates with the top of the housing 33. Hydrogen is injected into the inner cavity 331 of the housing 33 through the hydrogen pipe 35. Hydrogen has strong reducibility, which can reduce the oxidation of the fine tungsten wire 10 and other components during annealing, thereby improving the processing quality of the fine tungsten wire 10 and extending the service life of the equipment.
[0042] In a preferred embodiment of the present application, referring to Figure 3 , heat-insulating fibers 36 are filled inside the inductive coil 32. The heat-insulating fibers 36 can be materials such as asbestos, glass wool, and aluminum silicate fibers. The heat-insulating fibers 36 are wrapped around the circumference of the tungsten rod 31. The heat-insulating fibers 36 can prevent the heat transfer from the tungsten rod 31 to the inductive coil 32, thereby reducing the interference of high temperature on the performance of the inductive coil 32, being beneficial to maintaining the stability of the inductive coil 32, and further improving the stability of the annealing temperature.
[0043] In a preferred embodiment of the present application, referring to Figure 3 and Figure 5 , a support wheel set 6 is installed at both ends of the tungsten rod 31. Each support wheel set 6 includes two guide wheels 61. The fine tungsten wire 10 passes through the middle of the two guide wheels 61, and the circumferences of the two guide wheels 61 abut against the fine tungsten wire 10 from different directions, forming a bite on the fine tungsten wire 10. The support wheel sets 6 at both ends of the tungsten rod 31 respectively bite the two ends of the fine tungsten wire 10, straighten the fine tungsten wire 10 and pass it through the annealing hole 311 of the tungsten rod 31, so that the fine tungsten wire 10 walks along a straight line in the tungsten rod 31 for annealing, so that the surface of the fine tungsten wire 10 is heated more evenly, and further improves the uniformity of the annealing of the fine tungsten wire 10, which is beneficial to improving the processing quality of the fine tungsten wire 10.
[0044] Furthermore, referring toFigure 5 , the support assembly also includes a bracket 62 and a rotating plate 63. The bracket 62 is fixedly mounted on the frame 1, and the support is L-shaped. A rotating plate 63 is mounted on the top of the bracket 62, and a screw is mounted on the rotating center 631 of the rotating plate 63. The rotating plate 63 is fastened to the bracket 62 by the screw, and two guide wheels 61 are mounted on both sides of the rotating center 631. When the screw is loosened, the rotating plate 63 rotates around the screw, and the two guide wheels 61 rotate with the rotating plate 63; when the two guide wheels 61 reach the specified position, the screw is tightened to fix the position of the rotating plate 63 and the two guide wheels 61. In the process of the rotation of the two guide wheels 61, the contact position of the two guide wheels 61 and the thin tungsten wire 10 passing through the middle changes, and the degree of tightness changes. The thin tungsten wire 10 passing through the tungsten rod 31 is made tighter or looser by the two guide wheels 61, and the straight state of the annealed thin tungsten wire 10 is adjusted to meet different annealing process requirements.
[0045] Reference Figure 6 The measuring assembly 4 includes a counting wheel 41 and an encoder 42. The counting wheel 41 is fixedly mounted on the frame 1. The annealed thin tungsten wire 10 abuts against the top peripheral side of the counting wheel 41. The thin tungsten wire 10 drives the counting wheel 41 to rotate, and the length of the annealed thin tungsten wire 10 is measured by the circumference of the counting wheel 41. An encoder 42 is also mounted on the counting wheel 41. The encoder 42 is electrically connected to the control panel 11. The encoder 42 records the angular displacement of the counting wheel 41, transmits the information to the MCU of the control panel 11, and displays it through the digital display screen of the control panel 11, so that the operator can more intuitively count the length of the annealed tungsten wire, which is conducive to improving the efficiency of the annealing process of the thin tungsten wire.
[0046] Further, refer to Figure 6 The measuring assembly 4 further includes a wire pressing wheel 43, which is located on the side of the counting wheel 41 away from the tungsten rod 31. The bottom end of the wire pressing wheel 43 abuts against the thin tungsten wire 10 and presses the thin tungsten wire 10 downward, so that the thin tungsten wire 10 further fits the peripheral side of the counting wheel 41, increasing the friction between the thin tungsten wire 10 and the counting wheel 41, thereby increasing the measurement accuracy of the counting wheel 41.
[0047] Reference Figure 1 , refer to Figure 7, the wire winding assembly 5 includes a material receiving disk 51 and a driving motor 52. The material receiving disk 51 has the same shape and size as the feeding disk 22. The material receiving disk 51 is located on the side of the counting wheel 41 away from the tungsten rod 31. A fine tungsten wire 10 is adhesively bonded to the circumferential side of the material receiving disk 51. The rotation of the material receiving disk 51 can wind the annealed fine tungsten wire 10 and store the annealed fine tungsten wire 10. The driving motor 52 is installed on the frame 1, and a tensioning wheel 221 is installed on the output shaft of the driving motor 52. The material receiving disk 51 is installed on the circumferential side of the tensioning wheel 221. The driving motor 52 is electrically connected to the control panel 11, and the MCU on the control panel 11 controls the rotation speed of the driving motor 52. When the driving motor 52 rotates, the material receiving disk 51 rotates with the driving motor 52. The material receiving disk 51 pulls the fine tungsten wire 10 to wind around the circumferential side of the material receiving disk 51. On the one hand, it pulls the fine tungsten wire 10 on the frame 1 to perform wire feeding and continuous annealing. On the other hand, it stores the annealed fine tungsten wire 10, synchronously performing the wire feeding drive and storage steps of the annealing process, saving the working hours of the annealing process of the fine tungsten wire and being beneficial to improving the efficiency of the annealing process of the fine tungsten wire. When the material receiving disk 51 drives the fine tungsten wire 10 to feed wire, the fine tungsten wire 10 continuously slides in contact with the tungsten rod 31 in the annealing hole 311 for continuous annealing. By adjusting the rotation speed of the driving motor 52 through the control panel 11, the wire feeding speed of the fine tungsten wire 10 can be adjusted, so as to adjust the continuous annealing time of the fine tungsten wire 10, which is beneficial to improving the uniformity of the annealing process of the fine tungsten wire.
[0048] Further, referring to Figure 7 , a linear module 53 is further installed on the wire winding assembly 5. The linear module 53 reciprocates along the direction perpendicular to the threading direction of the fine tungsten wire 10. The driving motor 52 is installed on the top surface of the linear module 53 and slides with the linear module 53. When the material receiving disk 51 winds the fine tungsten wire 10, every time the fine tungsten wire 10 winds one turn around the circumferential side of the material receiving disk 51, the linear module 53 feeds or retreats a certain distance, so that the fine tungsten wire 10 is dispersed along the width direction of the material receiving disk 51, enabling more turns of the fine tungsten wire 10 to be wound on the same thickness layer of the material receiving disk 51, increasing the maximum length of the fine tungsten wire 10 that can be wound on the circumferential side of the material receiving disk 51, thereby increasing the utilization rate of the material receiving disk 51, reducing the working hours of replacing the material receiving disk 51, and being beneficial to improving the efficiency of the annealing process of the fine tungsten wire.
