Description

Technical Field

[0001] This invention belongs to the technical field of straightening processing equipment, specifically, it relates to a continuous straightening processing equipment for tungsten wires. Background Technology

[0002] In the field of tungsten wire cutting, there are requirements for the straightness of tungsten wire. For example, when a 100mm long tungsten wire is placed naturally on a flat plate, the baseline formed by the two ends of the tungsten wire and the fixed height formed by the bend cannot be higher than 3mm. However, in the actual production process of tungsten wire, due to the uncertainty of the mold and other processes, it is difficult to make the straightness of the tungsten wire consistent. Therefore, a device that can straighten and calibrate tungsten wire is needed.

[0003] In the existing technology, as shown in the appendix Figure 11 As shown, the axes of wheels a1 and b are perpendicular to the tungsten wire, and their centers are offset from the tungsten wire, forming a cosine wave arrangement between a1, b, and a2. This reduces and balances the residual stress within the tungsten wire. However, existing straightening methods are limited by the diameter of the guide wheels and the unevenness of the contact surface between the guide wheels and the tungsten wire. They are usually only suitable for thicker tungsten wires (such as 0.2 mm and above) and with a take-up speed of less than 5 m / s. Therefore, we propose a high-speed tungsten wire continuous straightening processing device and method. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a high-efficiency tungsten wire continuous straightening processing device that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a tungsten wire continuous straightening processing device, including a mounting frame, and further including: an internal gear ring rotatably mounted on the mounting frame, wherein a mounting plate is disposed in the internal gear ring, and a second eccentric sleeve is disposed at the eccentric part of the mounting plate; a first cylindrical shaft and a second cylindrical shaft are rotatably connected to the mounting frame respectively via bearings, wherein a first planetary gear set and a second planetary gear set are respectively disposed on the first cylindrical shaft and the second cylindrical shaft, and the first planetary gear set and the second planetary gear set... The components mesh with the internal teeth on both sides of the internal gear ring respectively; the first eccentric sleeve and the third eccentric sleeve are respectively eccentrically set on the first cylindrical shaft and the second cylindrical shaft, and the first eccentric sleeve and the third eccentric sleeve are coaxially set. When the first cylindrical shaft and the second cylindrical shaft rotate in the same direction, the internal gear ring rotates in the opposite direction to the first cylindrical shaft and the second cylindrical shaft, so that the tungsten wire passing through the first eccentric sleeve, the second eccentric sleeve and the third eccentric sleeve in sequence are surrounded by the rotating first eccentric sleeve, the second eccentric sleeve and the third eccentric sleeve and form a continuous cosine wave bend.

[0006] Preferably, both the first planetary gear set and the second planetary gear set include a connecting disc, meshing gears, and planetary gears. Two meshing gears are respectively fixedly connected to one end of the first cylindrical shaft and the second cylindrical shaft. The connecting disc is located on a mounting bracket. The first cylindrical shaft and the second cylindrical shaft are rotatably connected to the connecting disc via bearings. A plurality of planetary gears are circumferentially rotatably connected to the connecting disc. The planetary gears mesh with the internal teeth of the internal gear ring and the meshing gears. When the first cylindrical shaft and the second cylindrical shaft rotate, the planetary gears rotate on their own and simultaneously drive the internal gear ring to rotate.

[0007] Furthermore, a groove is formed on the outer periphery of the internal gear ring.

[0008] Furthermore, the first cylindrical shaft, the second cylindrical shaft, and the mounting plate are all provided with adjustment mounting grooves. One end of the adjustment mounting groove is concentric with the first cylindrical shaft, the second cylindrical shaft, and the mounting plate, respectively, and the other end of the adjustment mounting groove extends outward from the first cylindrical shaft, the second cylindrical shaft, and the mounting plate. The adjustment mounting groove is provided with an arc-shaped limiting groove. Both ends of the first eccentric sleeve, the second eccentric sleeve, and the third eccentric sleeve are respectively installed on the first cylindrical shaft, the second cylindrical shaft, and the mounting plate by locking nuts, so as to adjust the distance between the first eccentric sleeve, the second eccentric sleeve, and the third eccentric sleeve respectively.

[0009] Furthermore, a piston cylinder is fixedly connected to the connecting plate, and a piston rod with a piston at one end is slidably connected in the piston cylinder. The piston cylinder is divided into a first chamber and a second chamber by the piston on the piston rod. It also includes a telescopic nozzle with one end facing one end of the first eccentric sleeve and the third eccentric sleeve, respectively. A fixing ring is fixedly connected to the first cylindrical shaft and the second cylindrical shaft. A rotating groove is opened on the outer circumference of the fixing ring. A rotating ring is rotatably connected in the rotating groove. A telescopic nozzle is fixedly connected to the fixing ring. The telescopic nozzle is connected to the rotating groove. The first chamber, the second chamber and the rotating ring are connected to the rotating ring through a first air outlet pipe and a second air outlet pipe, respectively. A first air inlet pipe and a second air inlet pipe are respectively provided on the first chamber and the second chamber. A one-way valve is provided in the first air outlet pipe, the second air outlet pipe, the first air inlet pipe and the second air inlet pipe, respectively.

[0010] Preferably, a mounting shaft is fixedly connected to the connecting shaft of one of the planetary gears, an eccentric wheel is fixedly connected to the mounting shaft, and one end of the piston rod is slidably connected to the outer circumference of the eccentric wheel.

[0011] Preferably, it further includes a drive component connected to the first cylindrical shaft for driving the first cylindrical shaft to rotate.

[0012] Preferably, it also includes a rotatable pay-off reel, a take-up reel, guide rings located on both sides of the mounting frame, and a tensioning assembly, the tensioning assembly being used to tension the tungsten wire.

[0013] Preferably, a limiting ring is fixedly connected to the outer circumference of the internal gear ring, and the internal gear ring is rotatably connected to the mounting bracket through the limiting ring.

[0014] A method for continuous straightening of tungsten wire mainly includes the following steps:

[0015] S1. Pass the tungsten wire through the first eccentric sleeve, the second eccentric sleeve, and the third eccentric sleeve in sequence. Through the eccentric setting of the first eccentric sleeve, the third eccentric sleeve, and the second eccentric sleeve, a cosine wave shape is formed in the internal gear ring.

[0016] S2. Drive the first eccentric sleeve and the third eccentric sleeve to rotate in the opposite direction to the second eccentric sleeve, so that the tungsten wire passing through the space formed by the first eccentric sleeve, the third eccentric sleeve and the second eccentric sleeve forms a cosine wave shape, and the residual stress of the bending deformation on the surface of the tungsten wire is homogenized by the cosine wave shape, thereby achieving the purpose of straightening.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention forms a cosine wave shape in the internal gear ring by passing the tungsten wire through the first eccentric sleeve, the second eccentric sleeve and the third eccentric sleeve in sequence. The bending deformation of the cosine wave shape realizes the uniform distribution of residual stress of the tungsten wire. Moreover, the cosine wave shape formed in the device can enable the tungsten wire to be straightened and straightened continuously at a higher speed. Compared with the existing straightening method of tungsten wire, the device can further improve the straightening effect and straightening efficiency of ultrafine tungsten wire.

[0018] Furthermore, the lengths of the first, second, and third eccentric sleeves in this device are greater than those of the guide wheels in the prior art, resulting in a larger and more uniform contact surface for the tungsten wire. This allows for further homogenization of the residual stress in the tungsten wire, reducing the uneven distribution of residual stress and thus improving the straightening effect. In addition, the arrangement of the first, second, and third eccentric sleeves can accommodate tungsten wires of different diameters, enabling straightening of tungsten wires of different diameters compared to the prior art.

[0019] Meanwhile, the axial spacing between the first eccentric sleeve, the second eccentric sleeve, and the third eccentric sleeve in this device is adjustable, making it even more suitable for straightening and straightening tungsten wires of different diameters. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] Example: Refer to Figures 1-10 A tungsten wire continuous straightening processing device includes a mounting frame 1, and further includes: a limiting ring 16 fixedly connected to the outer circumference of an internal gear ring 11, the internal gear ring 11 being rotatably connected to the mounting frame 1 via the limiting ring 16; the mounting frame 1 is also provided with a limiting bracket, the internal gear ring 11 being rotatably connected to the limiting bracket for supporting both sides of the internal gear ring 11; a mounting plate 12 is provided in the internal gear ring 11, and a second eccentric sleeve 14 is provided at the eccentric part of the mounting plate 12; a first cylindrical shaft 2 and a second cylindrical shaft 3 are rotatably connected to the mounting frame 1 via bearings, and a first planetary gear set 21 and a second planetary gear set 31 are respectively provided on the first cylindrical shaft 2 and the second cylindrical shaft 3. Gear set 21 and second planetary gear set 31 mesh with the internal teeth on both sides of internal gear ring 11 respectively; first eccentric sleeve 26 and third eccentric sleeve 30 are eccentrically set on first cylindrical shaft 2 and second cylindrical shaft 3 respectively. When first cylindrical shaft 2 and second cylindrical shaft 3 rotate in the same direction, internal gear ring 11 rotates in the opposite direction to first cylindrical shaft 2 and second cylindrical shaft 3, so that the tungsten wire 5 passing through first eccentric sleeve 26, second eccentric sleeve 14 and third eccentric sleeve 30 in sequence is surrounded by the rotating first eccentric sleeve 26, second eccentric sleeve 14 and third eccentric sleeve 30 in a continuous cosine wave shape; it also includes a rotatable wire feeding reel 52, a wire taking reel 53 and guide rings 51 located on both sides of mounting frame 1;

[0035] In use, the tungsten wire 5 on the pay-off reel 52 passes through the guide ring 51 located on the left side of the mounting frame 1, then sequentially passes through the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30, and then passes through the guide ring 51 located on the right side of the mounting frame 1, and is wound onto the take-up reel 53. Both the pay-off reel 52 and the take-up reel 53 are rotated by a motor, which facilitates control of the pay-off and take-up speeds (see reference). Figure 4 , Figure 10 );

[0036] It also includes a drive assembly 4, which is connected to the first cylindrical shaft 2 and is used to drive the first cylindrical shaft 2 to rotate;

[0037] The first cylindrical shaft 2 is driven to rotate by the drive assembly 4. During the rotation of the first cylindrical shaft 2, the first planetary gear set 21 on the first cylindrical shaft 2 drives the internal gear ring 11 to rotate, thereby causing the second cylindrical shaft 3 to rotate in the same direction as the first cylindrical shaft 2. Therefore, the first cylindrical shaft 2 and the second cylindrical shaft 3 rotate in the same direction and at the same speed, while the mounting plate 12 in the internal gear ring 11 rotates in the opposite direction.

[0038] Reference Figure 4 The tungsten wire 5 passes sequentially through the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30, forming a continuous cosine wave shape in a relatively encircling manner. The cosine wave bending deformation achieves the equalization of residual stress in the tungsten wire 5, thereby effectively reducing the uneven distribution of residual stress in the tungsten wire 5. Moreover, compared with the guide wheel in the prior art, the contact method between the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 and the tungsten wire 5 in this device can make the contact surface of the tungsten wire 5 larger, which can further equalize the residual stress in the tungsten wire 5, thereby making the straightening and straightening effect better. At the same time, the setting of the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 can also adapt to tungsten wires 5 of different diameters, and compared with the prior art, it can straighten tungsten wires 5 of different diameters.

[0039] Meanwhile, this device can rotate through the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30, and the first eccentric sleeve 26 and the third eccentric sleeve 30 rotate in opposite directions to the second eccentric sleeve 14. Therefore, it can straighten the tungsten wire 5 in a circular manner and continuously in a cosine wave shape. Compared with the straightening effect of the tungsten wire 5 by the prior art, this device can further improve the straightening effect and efficiency of the tungsten wire 5 (it should be understood that the tungsten wire 5 itself does not rotate).

[0040] In one embodiment, the drive assembly 4 includes pulleys, a timing belt, and a motor. The pulleys are respectively mounted on the first cylindrical shaft 2 and the motor shaft, and are connected by the timing belt. The motor drives the first cylindrical shaft 2 to rotate.

[0041] In another embodiment, the drive assembly 4 includes gears and a motor. The gears are respectively mounted on the outer periphery of the first cylindrical shaft 2 and the motor shaft. The first cylindrical shaft 2 is driven to rotate by the meshing of the two gears.

[0042] Furthermore, referring to Figure 2 , Figure 10 In order to ensure the toughness of the tungsten wire 5, a high-frequency heating device 8 is set up to heat the tungsten wire 5 that is about to enter the first eccentric sleeve 26 before the tungsten wire 5 passes through the first eccentric sleeve 26. This is beneficial to improve the toughness of the straightened tungsten wire 5.

[0043] High-frequency heating equipment 8 is a technology that uses high-frequency electromagnetic fields to heat objects. When a high-frequency current passes through a conductor, an electromagnetic field is generated, and a current is generated inside the conductor, causing the conductor to heat up.

[0044] The high-frequency heating device 8 includes an asbestos insulation tube 81, a central tube 82, and a heating wire 83. The central tube 82 is installed in the asbestos insulation tube 81 through a bracket. The heating wire 83 is wound around the central tube 82. The positive electrode 831 and the negative electrode 832 of the heating wire 83 are both located at the outer end of the asbestos insulation tube 81. The tungsten wire 5 passes through the central tube 82 and is heated by the heating wire 83, thereby performing high-frequency heating on the tungsten wire 5. The asbestos insulation tube 81 is installed on an insulating bracket 84.

[0045] Reference Figure 1 , Figure 5 Both the first planetary gear set 21 and the second planetary gear set 31 include a connecting disc 22, a meshing wheel 24, and planetary gears 23. The two meshing wheels 24 are respectively fixedly connected to one end of the first cylindrical shaft 2 and the second cylindrical shaft 3. The connecting disc 22 is located on the mounting bracket 1. The first cylindrical shaft 2 and the second cylindrical shaft 3 are rotatably connected to the connecting disc 22 through bearings. Multiple planetary gears 23 are rotatably connected to the connecting disc 22 in a circumferential shape. The planetary gears 23 mesh with the internal teeth of the internal gear ring 11 and the meshing wheel 24 respectively. When the first cylindrical shaft 2 and the second cylindrical shaft 3 rotate, the planetary gears 23 rotate on their own and drive the internal gear ring 11 to rotate.

[0046] When the first cylindrical shaft 2 rotates, it will drive the meshing wheel 24 connected to the first cylindrical shaft 2 to rotate. The rotating meshing wheel 24 will drive the three planetary gears 23 meshing with it to rotate. The planetary gears 23 rotate in the opposite direction to the first cylindrical shaft 2. Since the planetary gears 23 are rotatably connected to the connecting plate 22 and the connecting plate 22 is connected to the mounting bracket 1, the planetary gears 23 will only rotate on their own axis. While rotating on their own axis, they will drive the internal gear ring 11 meshing with the planetary gears 23 to rotate. The rotation direction of the internal gear ring 11 is the same as the rotation direction of the planetary gears 23.

[0047] When the internal gear ring 11 rotates, it will drive the second cylindrical shaft 3 to rotate through the second planetary gear set 31. Therefore, the first cylindrical shaft 2 and the second cylindrical shaft 3 can rotate in the same direction through the first planetary gear set 21 and the second planetary gear set 31, while the internal gear ring 11 rotates in the opposite direction.

[0048] Furthermore, the first cylindrical shaft 2, the second cylindrical shaft 3, and the mounting bracket 1 are connected by bearings;

[0049] In one embodiment, the bearing inner diameter is provided with first teeth, and the outer periphery of the first cylindrical shaft 2 and the second cylindrical shaft 3 is provided with second teeth that mesh with the first teeth on the bearing inner diameter.

[0050] Reference Figure 1 , Figure 5 The inner gear ring 11 has a slot 15 on its outer periphery;

[0051] Since the second eccentric sleeve 14 is in the internal gear ring 11, by opening a slot 15 on the internal gear ring 11, it is convenient to insert the tungsten wire 5 that passes through the first eccentric sleeve 26, such as hooks and clips, into the second eccentric sleeve 14, and then pass it from the second eccentric sleeve 14 into the third eccentric sleeve 30.

[0052] Therefore, by opening the slot 15, it is easier to insert the tungsten wire 5.

[0053] Reference Figure 5 , Figure 6 The first cylindrical shaft 2, the second cylindrical shaft 3, and the mounting plate 12 are all provided with adjustment mounting grooves 13. One end of the adjustment mounting groove 13 is concentric with the first cylindrical shaft 2, the second cylindrical shaft 3, and the mounting plate 12 respectively, and the other end of the adjustment mounting groove 13 extends to the outer periphery of the first cylindrical shaft 2, the second cylindrical shaft 3, and the mounting plate 12. The adjustment mounting groove 13 is provided with an arc-shaped limiting groove 131. The two ends of the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 are respectively installed on the first cylindrical shaft 2, the second cylindrical shaft 3, and the mounting plate 12 through locking nuts 25, so as to adjust the distance between the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 respectively.

[0054] The mounting groove 13 is provided with multiple arc-shaped limiting grooves 131. The arc-shaped limiting grooves 131 can limit the position of the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30, and can also facilitate the adjustment of the distance between the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30. This facilitates the adjustment of the cosine wave-shaped top height between the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30, so as to adapt to the straightening requirements of tungsten wires 5 of different diameters.

[0055] This device can continuously and at high speed straighten tungsten wires 5 with a diameter of 0.03mm-0.18mm by adjusting the axial spacing between the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30.

[0056] Furthermore, the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 are made of wear-resistant materials, such as cemented carbide, or are coated with a wear-resistant coating on the inner wall of the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30.

[0057] Meanwhile, this device clamps the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 by using the locking nut 25. It can also adjust the position of the locking nut 25 on the first eccentric sleeve 26, the second eccentric sleeve 14, or the third eccentric sleeve 30, thereby adjusting the distance between the adjacent ends of the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30. This allows for convenient adjustment of the shape of the cosine wave bend, further improving the straightening effect and efficiency of the tungsten wire 5.

[0058] In addition, the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 in this device can also adjust the spacing between them in the horizontal axis to the range of 0.1-0.5mm, thereby satisfying the applicability and versatility of tungsten wire 5 straightening;

[0059] In this device, the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 are all clamped and fixed by locking nuts 25 connected to both ends, which facilitates the replacement of the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 and the adjustment of the spacing.

[0060] Reference Figure 9A piston cylinder 61 is fixedly connected to the connecting plate 22. A piston rod 63 with a piston at one end is slidably connected to the piston cylinder 61. The piston cylinder 61 is divided into a first chamber 601 and a second chamber 602 by the piston on the piston rod 63. It also includes a telescopic nozzle 67 with one end facing the first eccentric sleeve 26 and the third eccentric sleeve 30 respectively. A fixing ring 66 is fixedly connected to the first cylindrical shaft 2 and the second cylindrical shaft 3. A rotating groove 661 is opened on the outer circumference of the fixing ring 66. A rotating ring 662 is rotatably connected in the rotating groove 661. The telescopic nozzle 67 is fixedly connected to the fixing ring 66. The telescopic nozzle 67 and the rotating groove are connected to each other. 661 are connected; the first chamber 601, the second chamber 602 and the rotating ring 662 are connected by the first air outlet pipe 64 and the second air outlet pipe 6021 respectively. The first chamber 601 and the second chamber 602 are respectively provided with the first air inlet pipe 65 and the second air inlet pipe. The first air outlet pipe 64, the second air outlet pipe 6021, the first air inlet pipe 65 and the second air inlet pipe are respectively provided with one-way valves; a mounting shaft 6 is fixedly connected to the connecting shaft 231 of one of the planetary gears 23, and an eccentric wheel 62 is fixedly connected to the mounting shaft 6. One end of the piston rod 63 is slidably connected to the outer circumference of the eccentric wheel 62.

[0061] By setting a piston cylinder 61, this device can reciprocate to pull the piston rod 63 in the piston cylinder 61 while the planetary gear 23 rotates. When the piston rod 63 is pulled, air enters the first chamber 601 through the first air inlet pipe 65, and at the same time, the gas in the second chamber 602 is squeezed into the second air outlet pipe 6021 and sprayed from the telescopic nozzle 67 into the first eccentric sleeve 26 and the third eccentric sleeve 30 respectively.

[0062] When the eccentric wheel 62 pushes the piston rod 63, the second chamber 602 draws gas into the second chamber 602 through the second air inlet pipe. By squeezing the gas in the first chamber 601, the gas enters the telescopic nozzle 67 through the first air outlet pipe 64 and is discharged into the first eccentric sleeve 26 and the third eccentric sleeve 30. When the gas is injected, it can clean the tungsten wire 5 in the first eccentric sleeve 26 and the third eccentric sleeve 30, as well as the debris and foreign matter remaining in the first eccentric sleeve 26 and the third eccentric sleeve 30, so as to avoid the residue in the first eccentric sleeve 26 and the third eccentric sleeve 30 from having an adverse effect on the straightening effect of the tungsten wire 5.

[0063] By setting the fixed ring 66 and the rotating ring 662, it is convenient to supply gas to the telescopic nozzle 67, and it can also prevent the first air outlet pipe 64, the second air outlet pipe 6021 from getting tangled with the first cylindrical shaft 2 and the second cylindrical shaft 3.

[0064] In addition, in another embodiment, the above-described jet cleaning design may not be used; therefore, the device can selectively spray air into the first eccentric sleeve 26 and the third eccentric sleeve 30.

[0065] In one embodiment, the tension of the tungsten wire 5 can be adjusted by utilizing the speed difference between the rotation of the pay-off reel 52 and the take-up reel 53.

[0066] In another embodiment, a tensioning assembly 7 may be used to tension the tungsten wire 5.

[0067] The tensioning assembly 7 is located between the mounting frame 1 and the take-up reel 53. It is used to tension the tungsten wire 5 between the mounting frame 1 and the take-up reel 53 to further prevent loosening. This further tightens the tungsten wire 5, which is in a cosine wave shape between the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30, thereby improving the straightening effect of the tungsten wire 5.

[0068] The tensioning assembly 7 includes a connecting frame, on which guide posts are symmetrically mounted. A mounting plate is slidably connected between the two guide posts. A spring is installed between the mounting plate and the bottom of the guide posts. A counterweight wheel is rotatably connected to the mounting plate. The tungsten wire 5 passes through the counterweight wheel and slides on the guide posts, thereby tensioning the tungsten wire 5.

[0069] The spring on the mounting plate acts as a buffer to prevent the counterweight wheel from falling too fast during tensioning;

[0070] Therefore, this device is suitable for a speed design of 10,000 revolutions per minute, thereby enabling continuous straightening of the tungsten wire 5 at high speed and reducing the unevenness of residual stress on the surface of the tungsten wire 5.

[0071] Example: Refer to Figures 1-10 A method for continuous straightening of tungsten wire mainly includes the following steps:

[0072] S1. Pass the tungsten wire 5 through the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 in sequence. Through the eccentric setting of the first eccentric sleeve 26, the third eccentric sleeve 30 and the second eccentric sleeve 14, a cosine wave shape is formed in the internal gear ring 11.

[0073] S2. Drive the first eccentric sleeve 26 and the third eccentric sleeve 30 to rotate in the opposite direction to the second eccentric sleeve 14, so that the tungsten wire 5 passing through the space formed by the first eccentric sleeve 26, the third eccentric sleeve 30 and the second eccentric sleeve 14 forms a cosine wave shape, and the residual stress of the bending deformation on the surface of the tungsten wire 5 is homogenized by the cosine wave shape, thereby achieving the purpose of straightening.

[0074] This invention forms a cosine wave shape in the internal gear ring 11 by passing the tungsten wire 5 sequentially through the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30. The cosine wave bending deformation achieves a uniform distribution of residual stress in the tungsten wire 5. Compared with the guide wheel in the prior art, the contact method between the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 and the tungsten wire 5 in this device makes the contact surface of the tungsten wire 5 larger and more stable, which can further uniformly distribute the residual stress in the tungsten wire 5, thereby improving the straightening and straightening effect. At the same time, the arrangement of the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 can also accommodate more tungsten wires 5 of different diameters, and compared with the prior art, it can straighten tungsten wires 5 of different diameters.

[0075] Secondly, since the first eccentric sleeve 26, the second eccentric sleeve 14, and the third eccentric sleeve 30 can all rotate, and the first eccentric sleeve 26 and the third eccentric sleeve 30 rotate in opposite directions to the second eccentric sleeve 14, the tungsten wire 5 can be continuously bent and deformed in a cosine wave shape during the winding process, thereby enabling the tungsten wire 5 to be straightened and straightened continuously at a higher speed. Compared with the existing technology for straightening the tungsten wire 5, this device can further improve the straightening effect and efficiency of the tungsten wire 5, and is particularly suitable for straightening ultrafine tungsten wire 5.

[0076] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
