Description

Technical Field

[0001] The present application relates to the technical field of micro metal wire processing, and in particular to a continuous drawing and wire stretching device for special micro metal wires. Background Art

[0002] With the progress of technology and the development of the manufacturing industry, micro metal wire rods are increasingly widely used in multiple fields, such as consumer electronics, new energy vehicles, medical devices, and intelligent robots. These fields have put forward higher requirements for the diameter, precision, and performance of the wire rods, which has promoted the development of the stretching processing technology of micro metal wire rods.

[0003] A Chinese patent with the publication number CN209077446U and the name "A Metal Wire Rod Pretreatment Drawing Device", specifically, by combining a frame, an unwinding mechanism, a cleaning and straightening mechanism, a drawing mechanism, and an oiling and lubricating mechanism, through experimental optimization, the drawing device can pre-clean and straighten the metal wire rod, ensure that the metal wire rod is drawn with a stable appearance, and at the same time can oil and lubricate the metal wire rod during the drawing process, further improving the drawing quality and production efficiency.

[0004] When the above-mentioned existing technology is used, it can also realize the function of stretching the micro metal wire rod. However, during the stretching process of the metal wire rod, it cannot effectively heat the metal wire rod, resulting in poor plastic deformation ability of the metal wire rod, which is not conducive to eliminating or reducing the internal defects and stress concentration of the material, and affecting the subsequent stretching effect of the metal wire rod; secondly, after the metal wire rod is stretched, it cannot accurately wind and divide the metal wire rod, cannot finely control the shape and surface state of the metal wire rod, and cannot reduce the defects such as surface scratches and cracks generated during the stretching process, affecting the surface quality of the metal wire rod; based on this, there is still room for improvement on the basis of the existing micro metal wire rod surface treatment equipment.

Detailed implementation manners

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0034] Please refer to Figures 1-12, A continuous drawing and wire-drawing device for special fine metal wires provided in an embodiment of the present invention includes a frame 1; and a wire winding and unwinding assembly 2, which is installed on the lower left and right sides of the front side of the frame 1. The wire winding and unwinding assembly 2 is used for unwinding and winding the fine metal wire; a wire processing module, including a plurality of stretching assemblies 3 and a plurality of wire dividing assemblies 4. The stretching assemblies 3 and the wire dividing assemblies 4 are installed on the upper front end of the frame 1. The stretching assemblies 3 and the wire dividing assemblies 4 are in one-to-one correspondence. The wire winding and unwinding assembly 2 is used to drive the metal wire to pass through a stretching assembly 3 and a wire dividing assembly 4 in sequence. The stretching assembly 3 is used for layer-by-layer wire drawing of the fine metal wire, and the wire dividing assembly 4 is used for wire winding and guiding of the drawn metal wire; a control panel 5, which is installed on the upper end of the frame 1. The control panel 5 is electrically connected to the wire winding and unwinding assembly 2, the stretching assembly 3 and the wire dividing assembly 4.

[0035] In the above technical solution, the wire winding and unwinding assembly 2 includes a wire feeding frame and a winding frame. A winding motor is connected to the rear end of the winding frame. When processing the fine metal wire, first place the wire reel wound with the fine metal wire on the wire feeding frame, and then pass the end of the fine metal wire through the inside of the stretching assembly 3 and the wire dividing assembly 4 at intervals. The number of times the fine metal wire passes through the stretching assembly 3 and the wire dividing assembly 4 can be set according to the usage requirements, so that the fine metal wire can achieve the function of step-by-step stretching. The stretched fine metal wire is evenly wound by the winding frame. A controller is provided inside the control panel 5. The controller is used to adjust the winding speed of the winding motor, the temperature during stretching of the stretching assembly 3, and the wire dividing distance during wire guiding of the wire dividing assembly 4.

[0036] Refer to Figures 3-4 As shown in the figure, as a preferred technical solution of this embodiment, the stretching assembly 3 includes a mounting plate 31, a guide wheel 32, a wire guiding frame 33, a heating mechanism 34 and a drawing mechanism 35. The mounting plates 31 are evenly installed on the upper end of the front end face of the frame 1. The guide wheels 32 are symmetrically installed on the front end face of the mounting plate 31. The wire guiding frame 33, the heating mechanism 34 and the drawing mechanism 35 are installed on the front end face of the mounting plate 31 in sequence from left to right. The metal wire passes through the inside of the wire guiding frame 33, the heating mechanism 34 and the drawing mechanism 35 in sequence.

[0037] In the above technical solution, when the fine metal wire needs to be stretched, the guide wheel 32 guides the metal wire. The wire guiding frame 33 can ensure that the metal wire is on the same horizontal plane as the heating mechanism 34. The heating mechanism 34 can uniformly heat the fine metal wire. The heated fine metal wire passes through the inside of the drawing mechanism 35. The drawing mechanism 35 can perform stretching processing on the fine metal wire. During the stretching process, parameters such as stretching speed, stretching force and stretching temperature need to be controlled to ensure that the quality of the drawn wire meets the requirements.

[0038] It should be noted that heating the fine metal wire by the heating mechanism 34 helps to achieve uniform deformation of the fine metal wire during the stretching process. In the heated state, the fluidity and deformation ability of the fine metal wire are improved, and it can deform more uniformly along the stretching direction, avoiding material fracture or shape distortion caused by excessive local stress or uneven deformation. At the same time, at high temperatures, the grains of the fine metal wire may recrystallize or grow, which helps to eliminate or reduce internal defects and stress concentration phenomena in the material. This can not only improve the mechanical properties of the material, such as strength, toughness and fatigue resistance, but also reduce the fracture risk of the material during subsequent use.

[0039] Refer to Figures 5-6 As shown, as a preferred technical solution of this embodiment, the heating mechanism 34 includes a connecting frame 341, a cover frame 342, a wire guide wheel 343, a heating part 344 and an adjusting unit 345. The connecting frame 341 is installed at the front end of the mounting plate 31. A rotatable cover frame 342 is installed at the upper end of the connecting frame 341. A rectangular groove is provided inside the connecting frame 341. Rectangular openings communicating with the rectangular groove are provided on both sides of the connecting frame 341. A wire guide wheel 343 is installed in the rectangular groove through a bearing seat. The adjusting unit 345 is installed at the lower end inside the rectangular groove. The heating parts 344 are evenly installed between the upper ends of the adjusting unit 345. The heating part 344 is configured to heat the metal wire guided by the wire guide wheel 343.

[0040] In the above technical solution, when winding the fine metal wire, the adjusting unit 345 drives the heating part 344 to open, and the metal wire is wound through the two wire guide wheels 343. The fine metal wire between adjacent two wire guide wheels 343 is just located at the center position of the heating part 344. Then, the adjusting unit 345 closes the heating part 344, so that the heating part 344 can accurately and uniformly heat the fine metal wire. The cover frame 342 can further play a role in closing to reduce heat dissipation.

[0041] It should be noted that when heating the fine metal wire, multiple heating parts 344 can be used to achieve continuous heating, and the heating temperature of the heating part 344 for the fine metal wire increases sequentially to ensure the uniformity of heating the fine metal wire. At the same time, the heating temperature of the fine metal wire needs to be higher than the temperature during stretching to avoid the temperature of the fine metal wire being lower than the expected temperature during subsequent lubrication, preventing it from affecting the subsequent stretching effect of the fine metal wire.

[0042] Refer to Figure 6As shown, as a preferred technical solution of this embodiment, the heating part 344 includes two symmetrically arranged heating frames 3441. The cross-section of the heating frame 3441 is in a trapezoidal structure. An arc-shaped groove is provided on the inner side surface of the heating frame 3441, and a heat-insulating porcelain sleeve 3442 is installed in the arc-shaped groove. Heating rings 3443 are evenly arranged on the concave surface of the heat-insulating porcelain sleeve 3442.

[0043] In the above technical solution, the heating frame 3441 is connected to the adjusting unit 345. The adjusting unit 345 can drive the two symmetrically arranged heating frames 3441 to move synchronously inward or outward. When the two heating frames 3441 are closed and in close contact, the two heat-insulating porcelain sleeves 3442 are closed to form a closed circular cavity. The heat-insulating porcelain sleeve 3442 can effectively reduce heat dissipation, and the heating ring 3443 can accurately heat the fine metal wire. The heating effect is good, ensuring that the metal wire can be uniformly heated, improving the plastic deformation ability of the metal wire and ensuring the uniformity of the deformation.

[0044] Refer to Figure 5 As shown, as a preferred technical solution of this embodiment, the adjusting unit 345 includes a rectangular frame 3451 and an adjusting rod 3452. The rectangular frames 3451 are symmetrically installed in the rectangular groove. The interior of the rectangular frame 3451 is a hollow structure. The adjusting rod 3452 is installed in the rectangular frame 3451 through bearings. Multiple groups of external threads are provided on the adjusting rod 3452. Each group of external threads includes two oppositely arranged thread grooves. A threaded seat is installed on each thread groove by means of thread fit. The heating frame 3441 is installed at the upper end of the threaded seat.

[0045] In the above technical solution, the end of the adjusting rod 3452 is connected to the output shaft of the motor. When the motor works, the motor drives the adjusting rod 3452 to rotate at a constant speed. The two threaded seats on the same group of the adjusting rod 3452 rotate synchronously inward or outward, and thus the functions of synchronously opening and closing the two heating frames 3441 can be realized.

[0046] Refer to Figure 7 As shown, as a preferred technical solution of this embodiment, the drawing mechanism 35 includes a connecting frame 351, a lubricating unit 352, a drawing die 353 and a collecting frame 354. The connecting frame 351 is installed on the mounting plate 31. The connecting frame 351 is located on the right side of the heating mechanism 34. A rectangular groove is provided at the front end of the connecting frame 351, and the lubricating unit 352 is installed in the rectangular groove. An arc-shaped groove is provided on the lubricating unit 352, and the drawing die 353 is installed in the arc-shaped groove. The drawing die 353 is in a circular ring structure and is replaceably provided. A drawing die hole is provided in the middle of the drawing die 353. The heated fine metal wire is lubricated by the lubricating unit 352 and then drawn through the drawing die hole. A collecting frame 354 is provided at the lower end of the connecting frame 351.

[0047] In the above technical solution, the heated fine metal wire passes through the lubrication unit 352 and the inside of the drawing die 353 in sequence. The lubrication unit 352 first lubricates the heated metal wire. The lubricated fine metal wire passes through the inside of the drawing die 353. Lubrication can form a lubricating film on the surface of the metal wire. This film can significantly reduce the direct contact between the surfaces of the metal wires, thereby reducing the friction coefficient and making the drawing process smoother. At the same time, the lubricant can prevent the surface of the metal wire from being worn and scratched during the drawing process, maintaining the smoothness and integrity of the metal wire. By reducing friction and wear, the lubricant helps to maintain the shape and dimensional accuracy of the metal wire and improve the overall quality of the product. The excess lubricating fluid after lubrication is collected and filtered by the collection frame 354 for subsequent utilization of the lubricating fluid.

[0048] It should be noted that the sizes of the drawing die holes on the drawing die 353 are different, that is, the diameters of the drawing die holes through which the fine metal wire passes gradually decrease, so that the fine metal wire can achieve the function of layer-by-layer drawing and ensure the uniformity of the drawing of the fine metal wire.

[0049] Continue to refer to Figure 7 As shown, as a preferred technical solution of this embodiment, the lubrication unit 352 includes a lubrication frame 3521, a spray nozzle 3522 and a rubber sleeve 3523. The lubrication frame 3521 is in a rectangular structure. The lubrication frame 3521 is installed on a rectangular groove. A conical groove is provided in the middle of the lubrication frame 3521. Spray nozzles 3522 are evenly arranged on the inner side surface of the conical groove. A rubber sleeve 3523 is installed on the left side of the conical groove. An inlet is provided in the middle of the rubber sleeve 3523. Liquid outlet holes are evenly provided at the lower end on the right side of the conical groove. The liquid outlet holes are communicated with the collection frame 354.

[0050] In the above technical solution, the spray nozzles 3522 are evenly arranged on the inner side surface of the conical groove, so that the spray of the spray nozzles 3522 focuses on the same point. The spray nozzles 3522 atomize the lubricating fluid to form a mist curtain, so that the lubricating fluid can accurately contact the surface of the fine metal wire and ensure the uniformity of the lubrication of the metal wire. At the same time, the conical groove and the drawing die hole in the middle of the drawing die 353 form a lubrication interval. The rubber sleeve 3523 can play a role in closing the end of the conical groove to prevent the atomized lubricating fluid from diffusing outwards. The lubricating fluid aggregated after atomization flows into the inside of the collection frame 354 through the liquid outlet holes.

[0051] Refer to Figures 8-10 As shown, as a preferred technical solution of this embodiment, the wire splitting assembly 4 includes a fixing plate 41, an inclination unit 42, a guide wheel 43 and a wire splitting wheel 44. Fixing plates 41 are evenly installed at the front end of the frame 1. An inclination unit 42 is installed on the left side at the front end of the fixing plate 41. A guide wheel 43 is installed at the front end of the inclination unit 42. A wire splitting wheel 44 is installed on the right side at the front end of the fixing plate 41.

[0052] In the above technical solution, the fine metal wire after being stretched by the stretching die 353 is guided by the guide wheel 43 and then wound and divided by the wire dividing wheel 44. Through the process of winding and dividing the wire, the shape and surface state of the metal wire can be controlled more precisely, and defects such as surface scratches and cracks generated during the stretching process can be reduced, thereby improving the surface quality of the metal wire. At the same time, winding and dividing the wire helps to divide the metal wire into fine wires with the same or similar diameters, ensuring the accuracy and consistency of the product size and meeting the requirements of specific applications. The inclination unit 42 can adjust the inclination angle of the guide wheel 43. By changing the inclination angle of the guide wheel 43, the distance between multiple turns of the fine metal wire wound on the wire dividing wheel 44 can be adjusted, preventing the phenomenon of mutual interference between multiple turns of the fine metal wire wound on the wire dividing wheel 44. That is, the function of the inclined guide wheel 43 is to change the distance between the metal wires wound on the wire dividing wheel 44. The larger the inclination angle of the guide wheel 43, the larger the distance between the metal wires wound on the wire dividing wheel 44.

[0053] It should be noted that during the stretching process of the fine metal wire, the diameter of the metal wire can be further reduced through winding and dividing the wire, so as to obtain a finer metal wire product, which is particularly important for precision components in electronic devices. At the same time, through the winding and dividing process, its plasticity can be improved, and its workability and service life can be enhanced.

[0054] Refer to Figure 9 As shown, as the preferred technical solution of this embodiment, the inclination unit 42 includes a bearing seat 421, an arc-shaped slide rail 422, a sliding frame 423, a rectangular bracket 424 and a rotating shaft 425. A through hole is installed on the fixed plate 41, and the bearing seat 421 is installed in the through hole through a pin shaft. A rectangular bracket 424 is provided at the front end of the fixed plate 41, and a round hole matching the bearing seat 421 is provided on the rectangular bracket 424. A rubber layer is installed between the bearing seat 421 and the round hole. The rotating shaft 425 is installed in the bearing seat 421 through a bearing, and the guide wheel 43 is installed at the front end of the rotating shaft 425. The arc-shaped slide rail 422 is installed at the rear side of the fixed plate 41, and the sliding frame 423 is slidably arranged in the middle of the arc-shaped slide rail 422. The middle of the sliding frame 423 is connected to the rotating shaft 425.

[0055] In the above technical solution, when it is necessary to adjust the inclination angle of the guide wheel 43, the rotating shaft 426 can rotate synchronously with the bearing seat 421, and the guide wheel 43 at the end of the rotating shaft 426 can accurately guide the fine metal wire. When the arc-shaped slide rail 422 drives the rotating shaft 425 to adjust the angle through the sliding frame 423, the rotating shaft 425 can drive the guide wheel 43 to adjust synchronously, and thus the inclination angle of the guide wheel 43 can be accurately adjusted.

[0056] Refer to Figures 11-12As shown, as the preferred technical solution of this embodiment, a tensioning mechanism 6 is evenly installed at the front end of the frame 1. The fine metal wire passing through the inside of the stretching assembly 3 needs to be tensioned and adjusted by the tensioning mechanism 6. The tensioning mechanism 6 includes a rectangular plate 61 and a tensioning unit 62. The rectangular plate 61 is installed on the front end face of the frame 1, and the tensioning unit 62 is installed on the front end face of the rectangular plate 61. The tensioning force of the tensioning unit 62 is adjustable.

[0057] In the above technical solution, the tensioning unit 62 is used to adjust the tensioning force of the fine metal wire, so that the fine metal wire can always be in a taut state. The tensioning unit 62 can automatically adjust the tensioning force according to the actual situation to adapt to the change of the load, ensuring the stability and reliability of the fine metal wire during the stretching process.

[0058] It should be noted that the number of the tensioning mechanisms 6 is multiple. When the fine metal wire needs to pass through the inside of a drawing mechanism 35, at this time, the tensioning mechanism 6 is required to tension the metal wire. During the stretching process, the metal wire may undergo small displacements or deformations due to uneven stress or external factors (such as temperature changes, vibrations, etc.).
