Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of non-ferrous metal processing, and particularly relates to a tantalum wire cleaning and winding device and a winding method. BACKGROUND

[0002] Tantalum wire is an important metal material and is widely used in industrial production, such as tantalum wire for capacitors. From tantalum powder raw material to finished tantalum wire, it needs to go through multiple processing procedures, such as sintering, multiple rolling, multiple washing, multiple annealing, multiple drawing, etc. In the intermediate processing of tantalum wire, the tantalum wire with a diameter within a certain range needs to be cleaned and directly coiled, and then the whole coil is put into a vacuum heat treatment furnace for annealing to improve the microstructure of the tantalum wire, so as to provide preparation in terms of organization and performance for subsequent further processing.

[0003] When the tantalum wire is cleaned and wound into a coil, a special metal wire winding device needs to be configured, and the winding process is also a key link of metal wire processing. The existing metal wire winding machine sets the outer side wall of the winding drum as a conical surface, such as the extrusion winding drum disclosed in Chinese Patent CN213595642U, which comprises a drum, a base plate and a metal rod. When winding, due to the existence of the inclination angle, the wire material produced later will extrude the wire material wound previously upward, and then the wire material is wound row by row on the drum and the material rack to complete the winding process. Chinese Patent CN207343483U discloses a steel wire winding drum, the outer side wall of the drum is set as a conical surface, a wire clamping traction guide groove along the generatrix direction is arranged on the conical surface and cooperates with the wire clamping traction, when the winding drum rotates, the wire clamping traction always keeps tangential to the whole winding drum, and as the steel wire is wound on the surface of the winding drum, the wire clamping traction moves automatically along the wire clamping traction guide groove to the small end of the winding drum, so as to avoid the coverage of the wire clamping traction by the steel wire.

[0004] However, the existing metal wire winding drum is only suitable for ordinary metal wire, and is not suitable for tantalum wire with high density and strict requirements on surface quality. For example, the large taper of the drum, the traditional extrusion winding method makes the tantalum wire with high density prone to sliding and stacking, which can easily lead to wire disorder and winding phenomenon during the winding process, and the inner coil size after winding is not uniform, the wire coil is loose and disorderly, and the wire is disorderly during subsequent processing. For example, the anti-wear performance and smoothness of the steel drum surface are not strictly limited, and the rough surface or scratches of the drum surface not only easily scratch the surface of the tantalum wire, but also easily contaminate the tantalum wire with iron rust, which can easily cause the tantalum wire to exceed the standard of iron ions during subsequent heat treatment, and finally seriously affect the quality of the tantalum wire. In addition, if the weight of the single coil of tantalum wire wound is light or a wire arranging device is specially added, the production efficiency will be reduced or the complexity of the process equipment will be increased. SUMMARY

[0005] In view of the above technical problems, the present application provides a tantalum wire cleaning and take-up device and a take-up method to solve at least one of the following technical problems existing in the cleaning and take-up of the tantalum wire: (1) difficulty in winding the tantalum wire, easy tangling of the wire, loose and disordered wire reel, and tangled wire during unwinding; (2) scratching of the tantalum wire surface by the surface of the rotating drum during take-up; and (3) contamination of the tantalum wire by rust on the surface of the rotating drum during take-up.

[0013] Further, the wire unwinding machine comprises a wire unwinding wheel, a magnetic powder tensioner, a magnetic powder tensioner controller and an initial guide wheel.

[0014] In another aspect, the application also provides a wire winding method of the above device, the method being that the tantalum wire wound on the wire unwinding wheel is controlled to be unwound by the magnetic powder tensioner controller and the magnetic powder tensioner, the tantalum wire enters the cleaning unit for cleaning after passing through the initial guide wheel and the incoming wire guide wheel, enters the rinsing unit for rinsing after cleaning, enters the straightener for straightening after rinsing and passing through the outgoing wire guide wheel and the first wire arranging guide wheel, and enters the rotating drum for winding after straightening and passing through the second wire arranging guide wheel.

[0019] Compared with the prior art, the application can at least achieve one of the following technical effects:

[0020] ​(1) The size of the taper angle of the upper drum body and the lower drum body of the present application is adapted to the high density of the tantalum wire, so that the tantalum wire is wound from the root of the lower drum body as the drum rotates, and the layers of the tantalum wire are pressed and gradually move upwards. The upward pressing force generated by the pressing and the gravity of the tantalum wire are relatively balanced, so the tantalum wire is relatively easy and uniform to wind.

[0021] (2) The taper angle of the lower drum body of the present application is slightly smaller than the taper angle of the upper drum body or is 2°, which can make the tantalum wire move upwards smoothly and be wound, and will not fall to the lower drum body due to the increase of the number of turns. The taper angle of the upper drum body is just right to make the winding of the tantalum wire more layered, and will not cause tangled wires due to the change of the diameter of the drum body.

[0022] (3) The lower drum body and the upper drum body of the present application are connected by a 45°×4mm chamfer, which divides the drum into a winding work area of the lower drum body and a winding stable area of the upper drum body. The chamfer step can prevent the tantalum wire turns of the upper drum body from falling to the lower drum body.

[0023] (4) The bottom plate and the lower drum body of the present application are connected by an obtuse angle, which avoids the phenomenon of tangling and overlapping of the tantalum wire when it just enters the drum, so that the winding and take-up can be smoothly carried out.

[0024] (5) The surface coating of the present application has good hardness, smoothness and corrosion resistance, which reduces friction, facilitates the upward movement of the tantalum wire and prevents the tantalum wire from being scratched. It also prevents the drum from rusting and contaminating the tantalum wire due to water stains during cleaning.

[0025] (6) The distance and angle between the straightening rollers of the present application can be adjusted in real time according to the diameter of the tantalum wire to adapt to tantalum wires of different specifications and ensure the straightening accuracy.

[0026] (7) The two rows of straightening rollers of the present application are staggered at a certain angle. When the tantalum wire passes through the staggered straightening rollers, it is forced to bend in the opposite direction several times. This repeated plastic deformation gradually eliminates the internal stress of the tantalum wire caused by rolling and storage, and the diameter of the bent tantalum wire is > 3 meters.

[0027] (8) The present application matches the wire tension and the diameter of the tantalum wire, the take-up speed and the cleaning speed, and the process parameters of the wire unwinding, cleaning, rinsing, drying, straightening and take-up processes are matched and coordinated with each other, ensuring smooth and efficient operation of the entire process.

DETAILED DESCRIPTION

[0037] Figure 1A process flow chart for preparing tantalum wire. After sintering, twice rolling, twice acid water washing, twice annealing, and tantalum wire drawing 1 from raw materials, tantalum wire with a diameter of about 0.3-1.5 mm is obtained, then a tantalum wire cleaning process is carried out, the tantalum wire is cleaned and coiled, and then the whole coil of tantalum wire is placed in a vacuum heat treatment furnace for annealing treatment, i.e. the tantalum wire annealing 2 process. After the tantalum wire annealing 2 process, the tantalum wire improves the structure and performance, and can be subjected to the next tantalum wire drawing 2 process, at this time the whole coil of tantalum wire needs to be unwound and drawn, and tantalum wire with a smaller diameter than that after tantalum wire drawing 1 is obtained, and then cleaning and precision winding are carried out to obtain finished tantalum wire. In the tantalum wire processing, the surface quality, smoothness and the like are strictly required, surface scratches, contamination and straightness deterioration cannot occur in the processing, and in the annealing link of the coiled tantalum wire, adhesion between the tantalum wires is prone to occur, if the wire is tangled and the winding level is chaotic during winding, the adhesion will be more serious after annealing, and in the unwinding process, surface wear or failure to untangle is prone to occur, resulting in a decrease in the tantalum wire yield.

The coiling machine 1 comprises a rotating drum 10 and a wire guiding mechanism 11. The rotating drum 10 comprises a bottom disc 100, a lower drum body 101, an upper drum body 102, an axle hole 103, three wire bundling grooves 104, three vertical rod holes 105 and three vertical rods 106. The wire guiding mechanism 11 comprises a straightener 110, a first wire arranging guide wheel 111 and a second wire arranging guide wheel 112.

[0039] Specifically, the rotating drum 10 is roughly in the shape of a large lower and small upper circular table, and sequentially comprises a bottom plate 100, a lower drum body 101, an upper drum body 102 and a vertical pole 106 from bottom to top. The shaft hole is located at the center of the rotating drum. Three yarn bundling grooves are evenly distributed on the outer surfaces of the upper drum body, the lower drum body and the bottom plate. Three vertical pole holes are evenly distributed on the top surface of the circular ring of the upper drum body, and the vertical pole holes are matched with the vertical poles. In order to connect with other equipment on the production line and match the production capacity, the diameter of the bottom plate 100 of the rotating drum 10 is 250-300 mm, such as 260 mm, and the height is 20-40 mm, such as 30 mm. The maximum diameter of the bottom of the lower drum body 101 is 190-240 mm, such as 200 mm, and the height is 20-30 mm, such as 25 mm. The angle α between the generatrix of the lower drum body and the vertical line of the bottom surface of the rotating drum is 1.5-2.0°. The height of the upper drum body 102 is 150-200 mm, such as 160 mm. The angle β between the generatrix of the upper drum body and the vertical line of the bottom surface of the rotating drum is 2.0-2.5°. The transition angle between the bottom plate 100 and the lower drum body 101 is an obtuse angle, such as 120-150°. The transition angle between the lower drum body 101 and the upper drum body 102 is a 45°×4 mm chamfer. The shaft hole 103 is located at the center of the rotating drum, and the diameter of the shaft hole is about 40-50 mm, such as 45 mm, and the height is 80-120 mm, such as 100 mm. The shaft hole 103 is matched with the shaft of the power traction device to drive the rotating drum 10 to rotate and collect the yarn. In order to reduce the weight of the rotating drum and reduce the energy consumption of rotation, the rotating drum is hollow as much as possible under the premise of maintaining the size of the shaft hole and the normal rotation of the rotating drum, and the thickness of the rotating drum wall is not less than 10 mm. The three yarn bundling grooves 104 are rectangular in cross section and are evenly distributed in the circumferential direction of the outer surface of the rotating drum. The yarn bundling grooves extend along the generatrix of the rotating drum, longitudinally through the outer surfaces of the upper drum body 102 and the lower drum body 101, and extend into the bottom plate 100 by about 5 mm. The opening width of the rectangular yarn bundling groove 104 is about 15 mm, and the depth is about 8 mm. On the top surface of the circular ring of the upper drum body 102, three vertical pole holes 105, such as M5 screw holes with a depth of 10 mm, are evenly distributed vertically to the top surface of the circular ring. The three vertical pole holes 105 and the three yarn bundling grooves 104 are distributed in a staggered manner in the circumferential direction of the rotating drum, and the vertical pole holes 105 are matched with the vertical poles 106. The diameter of the vertical pole 106 is consistent with that of the vertical pole hole, and the length is about 100 mm.

[0040] The material of the rotating drum 10 is steel, such as Q195, Q235 and the like. The outer surfaces of the lower drum body 101 and the upper drum body 102 are plated with chromium or tungsten carbide, the thickness of the coating is 150-200 μm, the hardness of the coating is HRC65±2, and the surface roughness is not greater than 1.6. Because the coating is relatively dense, the corrosion current is less than 10 -7A / cm², the corrosion resistance is about 1000 times of ordinary carbon steel. When chromium plating, the to-be-plated rotating drum is used as the cathode, and the pure chromium plate is used as the anode, and they are immersed in the electrolyte containing chromium acid. After power on, the chromium ions in the electrolyte are reduced to metal chromium on the cathode surface and deposited to form a coating. The pretreatment needs to remove oil, rust and polish the metal surface to ensure that the surface is free of impurities and the adhesion of the coating. The current density, electrolysis time and temperature are controlled during electrolytic deposition, usually at 50-60℃, and the coating thickness is controlled according to the requirements to be 0.15-0.2mm, which can balance the cost and use effect. Finally, cleaning, drying, polishing or passivation are performed to improve the surface finish and corrosion resistance. The rotating drum is a winding mechanism stabilized by tantalum wire, and its smooth surface not only allows the tantalum wire to move up evenly and be wound, but also avoids scratching the surface of the tantalum wire. A small amount of water stains remaining after cleaning and winding will not rust the surface of the coating, thereby affecting the product quality.

[0041] The second wire guide wheel 112 in the rotating drum 10 and the wire guide mechanism 11 is process-connected, the second wire guide wheel 112 and the outgoing end of the straightener 110 are process-connected, and the first wire guide wheel 111 and the incoming end of the straightener 110 are process-connected. The straightener 110 is provided with a plurality of straightening rollers in two rows parallel to each other, and the upper row has one less straightening roller than the lower row. For example, the lower row has 8-12 straightening rollers 1101, and the diameter D of the straightening rollers 1101 is about 10mm. The two rows of straightening rollers are not symmetrically arranged, but are staggered at a certain angle. The spacing and angle between the straightening rollers 1101 can be adjusted in real time according to the diameter of the tantalum wire. Figure 6 The spacing B between the two rows of straightening rollers shown in the assembly diagram, the spacing K between two adjacent straightening rollers, and the angle θ between the axis of the two adjacent straightening rollers and the vertical line can be adjusted in real time.

[0042] The incoming end side of the cleaning unit in the cleaning machine 2 and the incoming guide wheel 24 in the wire guide unit are process-connected, the outgoing end side of the cleaning unit and the incoming end side of the rinsing unit are process-connected, and the outgoing end side of the rinsing unit and the outgoing guide wheel 25 in the wire guide unit are process-connected. The cleaning station 20 in the cleaning unit and the cleaning circulating tank 23 are adjacent to each other, and the cleaning station 20 is located above the cleaning circulating tank 23; the rinsing station 21 in the rinsing unit and the rinsing circulating tank 22 are adjacent to each other, and the rinsing station 21 is located above the rinsing circulating tank 22.

[0043] The cleaning station 20 is in a groove shape, and a water heater is installed inside, and a plurality of ultrasonic vibration plates, such as four ultrasonic vibration plates, are installed around the inside, and the power is 2kW, and the vibration frequency of 28kHz can be generated. A circulating water pump is installed between the cleaning station 20 and the cleaning circulating tank 23, and a 15um high-efficiency filter is additionally installed on the circulating pipeline. The rinsing station 21 is in a double-groove shape, including a rinsing tank and a drying tank, a water heater is installed inside the rinsing tank, and a plurality of ultrasonic vibration plates, such as four ultrasonic vibration plates, are installed around the inside, and the power is 2kW, and the vibration frequency of 28kHz can be generated; a hot air machine, such as a Roots hot air blower, is installed in the drying tank. A circulating water pump is installed between the rinsing tank and the rinsing circulating tank 22, and a 15um high-efficiency filter is additionally installed on the circulating pipeline.

[0044] For the above-mentioned tantalum wire cleaning and winding device, the application also provides a winding method using the above-mentioned tantalum wire cleaning and winding device. The method is as follows: the tantalum wire wound on the unwinding wheel 30 is controlled to be unwound by the magnetic powder tensioner controller 32 and the magnetic powder tensioner 31, enters the cleaning unit for cleaning after the initial guide wheel 33 and the wire guide wheel 24, enters the rinsing unit for rinsing after cleaning, enters the straightener 110 for straightening after the wire guide wheel 25 and the first wire guide wheel 111, and enters the rotating drum 10 for winding after straightening, and the rotating drum 10 rotates to wind the tantalum wire into a roll.

[0045] Specifically, the unwinding wheel 30 is restricted by the magnetic powder tensioner 31, and the magnetic powder tensioner 31 is controlled by the magnetic powder tensioner controller 32, so that the tension f of the tantalum wire unwinding is controlled within a suitable range, such as 10N

[0046] Specifically, the purpose of the cleaning unit is to wash away the drawing oil and other impurities left over from the previous process. The drawing oil is a high-viscosity fluorine oil. The cleaning method is ultrasonic cleaning, with a power of 2kW and a vibration frequency of 28kHz. A cleaning liquid is installed inside the cleaning station 20. The cleaning liquid is prepared according to the volume ratio of high-efficiency cleaning agent to water as 1:20-30, and the high-efficiency cleaning agent is NC-208 high-efficiency oil removal agent. The cleaning liquid is heated to 55-58℃. The cleaning liquid circulates between the cleaning station 20 and the cleaning circulating tank 23, and the high-efficiency filter on the circulating pipeline filters the oil and other impurities removed during cleaning. The cleaning rate is 16-30m / min.

[0047] Specifically, the purpose of the rinsing unit is to wash the cleaning solution remaining on the surface of the tantalum wire after cleaning and to dry it. The rinsing method is ultrasonic rinsing, the power is 2 kW, and the vibration frequency is 28 kHz. Tap water is heated to 55-60℃ and is circulated between the rinsing tank and the rinsing circulating tank 22. The high-efficiency filter on the circulating pipeline filters the water quality. After rinsing, the tantalum wire enters the drying tank and is blown dry by hot air with an air volume of about 1.5-3.0 m 3 / min, an air speed of about 12.8-25.5 m / s, and an outlet temperature of about 40-60℃. The rinsing rate is consistent with the cleaning rate.

[0048] After cleaning, most of the oil stains on the surface of the tantalum wire are removed, and the naked eye can see the brightness. Wiping with a white cloth does not leave oil stains, and a small amount of residual oil stains do not affect the performance of the tantalum wire. In order to further verify the cleaning effect, the cleaned tantalum wire will be cut into pieces, and the surface CHO element will be detected. Usually, it is less than 10 ppm, indicating that it meets the requirements.

[0049] Specifically, the straightener continuously extrudes and bends the tantalum wire through multiple sets of straightening rollers 1101, finally eliminating the internal stress of the tantalum wire, and making it meet the straightness requirement. The tantalum wire is first uniformly fed into the straightener 110 by the first row of wire guide wheels 111. When the tantalum wire passes through the staggered straightening rollers 1101, it will be forced to bend in the opposite direction multiple times, such as bending in one direction first, and then bending in the opposite direction. Through this repeated plastic deformation, the internal stress of the tantalum wire generated due to rolling and storage is gradually eliminated. The spacing and angle between the straightening rollers 1101 can be adjusted in real time according to the diameter of the tantalum wire to adapt to tantalum wires of different specifications and ensure straightening accuracy. Specifically, when the spacing K between two adjacent upper and lower straightening rollers is equal to the diameter d of the tantalum wire, there is a mathematical relationship between the diameter D of the straightening roller, the spacing K between two adjacent upper and lower straightening rollers, the spacing B between the two parallel rows of straightening rollers, and the angle θ between the axis line of the two adjacent upper and lower straightening rollers and the vertical line, which is K = (B + D) / cos θ - D. The spacing B between the two parallel rows of straightening rollers is about 1 / 3 of the diameter d of the tantalum wire. For example, when the diameter D of the straightening roller is 10 mm and the diameter d of the tantalum wire is 1 mm, the spacing B between the two parallel rows of straightening rollers is 0.3366 mm, and the angle θ between the axis line of the two adjacent upper and lower straightening rollers and the vertical line is 20°, so that the spacing K between the two adjacent upper and lower straightening rollers is equal to the diameter d of the tantalum wire. Because of the unique metal properties of the tantalum wire, by adjusting the spacing and angle of the straightening rollers, the internal stress of the tantalum wire is eliminated after straightening and the tantalum wire remains relatively flat. The diameter of the bent tantalum wire is greater than 3 meters, which meets the requirements of tantalum wire winding, makes the elastic recovery force of the wound tantalum wire small and consistent, and reduces the possibility of tangled wire. Finally, the tantalum wire that meets the requirements is uniformly output through the second row of wire guide wheels 112, completing the entire straightening process.

[0050] Specifically, the wire end of the tantalum wire is tied on the vertical pole 106 after entering the rotating drum 10, and the tantalum wire is wound from the root of the lower drum body 101 with the rotation of the rotating drum 10. The second wire guide roller 112 can adjust the tantalum wire to keep the optimal entry position stable. The tantalum wire is pressed layer by layer and gradually moves upward, and the upward pressing force generated by the pressing and the gravity of the tantalum wire are relatively balanced, so the tantalum wire is relatively easy and uniform to wind. In addition, the surface roughness of the drum body is not greater than 1.6, and the good wear resistance and corrosion resistance of the surface coating make the surface of the drum body smooth for a long time. Since the specific gravity of the tantalum wire is large, the taper angle α of the lower drum body and the taper angle β of the upper drum body are designed to be small, not more than 2.5°. When the taper angle of the lower drum body and the taper angle β of the upper drum body are both 2° or α is slightly smaller than β, β-α=0.5° is preferred. In this way, the tantalum wire can smoothly move upward and wind, and will not fall to the lower drum body due to the increase of the number of turns. The taper angle β of the upper drum body can also make the winding of the tantalum wire more layered, and will not cause the tantalum wire to be tangled due to the change of the diameter of the drum body. The take-up tension of the rotating drum is balanced with the pay-off tension, and the linear velocity of the rotating drum is consistent with the cleaning and rinsing speed. Since the coating on the surface of the rotating drum has good hardness, smoothness and corrosion resistance, friction is reduced, the tantalum wire is less likely to be scratched, and the rotating drum is less likely to rust and contaminate the tantalum wire due to water stains during cleaning. In summary, the reasonable design of the structure and surface coating of the rotating drum effectively prevents the tantalum wire from tangling and winding during take-up, ensures uniform winding, and improves product quality.

[0051] Finally, after the tantalum wire is taken up and wound, the binding wire is inserted from the wire binding groove 104 to complete the binding of the tantalum wire coil, and the weight of a coil of tantalum wire is about 4-6 kg. The bound tantalum wire coil enters the next process, and the entire coil is placed in a vacuum heat treatment furnace for annealing treatment.

[0052] The take-up machine of the present application does not cause the tantalum wire to tangle during winding, has a clear layered appearance, has appropriate gaps between the tantalum wires, has less adhesion of the tantalum wire after winding and annealing, and even if there is some adhesion, it can be easily separated without scratching the surface.

The power of the ultrasonic vibration plates is 2 kW, and the vibration frequency is 28 kHz. A Roots hot air blower is installed in the drying groove. A circulating water pump is installed between the rinsing groove and the rinsing circulating tank 22, and a 15 μm high-efficiency filter element is additionally installed in the circulating pipeline.

[0090] The wire winding method using the above tantalum wire cleaning and winding device is as follows. The tantalum wire with a diameter of 1.5 mm wound on the wire unwinding wheel 30 is controlled to be unwound by the magnetic powder tensioner controller 32 and the magnetic powder tensioner 31, enters the cleaning unit for cleaning after the initial guide wheel 33 and the incoming guide wheel 24, enters the rinsing unit for rinsing after cleaning, enters the straightener 110 for straightening after the outgoing guide wheel 25 and the first wire guide wheel 111, and enters the rotating drum 10 after straightening. The rotating drum 10 rotates to wind the tantalum wire into a roll.

[0091] Specifically, the wire reel 30 is restricted by the magnetic powder tensioner 31, and the magnetic powder tensioner 31 is controlled by the magnetic powder tensioner controller 32, so that the tension f of the tantalum wire is controlled at 15 N.

[0092] Specifically, the cleaning mode of the cleaning unit is ultrasonic cleaning, the power is 2 kW, a plurality of ultrasonic vibration plates are installed around the inside of the cleaning station 20 to generate a vibration frequency of 28 kHz, cleaning liquid is filled in the cleaning station 20, the cleaning liquid is prepared according to a volume ratio of 1:25 of high-efficiency cleaning agent and water, the high-efficiency cleaning agent is NC-208 high-efficiency degreasing agent, and the cleaning liquid is heated to 56.5°C. The cleaning liquid is circulated between the cleaning station 20 and the cleaning circulating tank 23, and the high-efficiency filter element on the circulating pipeline filters the impurities such as oil stains removed by cleaning. The cleaning speed is 23 m / min.

[0093] The rinsing mode is ultrasonic cleaning with a power of 2 kW, which can generate a vibration frequency of 28 kHz. Tap water is filled in the rinsing tank of the rinsing station 21, and the water temperature is heated to 58°C. The tap water is circulated between the rinsing tank and the rinsing circulating tank 22, and the high-efficiency filter element on the circulating pipeline filters the water quality. After rinsing, the tantalum wire enters the drying tank and is blown dry by the air blower, with an air volume of 3.0 m / min, an air speed of 19 m / s, and an outlet temperature of 50°C. The rinsing speed and the cleaning speed are consistent. 3

[0094] Specifically, the tantalum wire is first uniformly fed into the straightener 110 by the first wire guide wheel 111, the spacing B between the upper and lower straightening rollers parallel to each other is 0.5 mm, the included angle θ between the axis line of the two adjacent upper and lower straightening rollers and the vertical line is 24.1°, so that the spacing K between the two adjacent upper and lower straightening rollers is equal to the diameter d of the tantalum wire, which is 1.5 mm. Finally, the tantalum wire is uniformly output through the second wire guide wheel 112, and the entire straightening process is completed.

[0095] Specifically, after the tantalum wire enters the rotating drum 10, the wire end of the tantalum wire is tied on the vertical rod 106, the tantalum wire is wound from the root of the lower cylinder body 101 under the rotation of the rotating drum 10, and the tantalum wire is pressed layer by layer and gradually moves upward. The winding force of the rotating drum is balanced with the wire releasing tension, which is 15 N; the linear speed of the rotating drum is consistent with the cleaning and rinsing speed, which is 23 m / min.

[0096] Finally, after the tantalum wire is wound into a roll, the binding wire is inserted into the wire binding groove 104 to complete the binding of the tantalum wire roll. The binding wire used is a special binding tantalum wire, and the weight of one roll of tantalum wire is 5 kg. The bound tantalum wire roll enters the next process, and the whole roll is put into a vacuum heat treatment furnace for annealing treatment.

[0097] ​The surface of the tantalum wire in this embodiment is bright under naked eyes, and no oil stains are found when wiping with white cloth. After straightening, the internal stress of the tantalum wire is eliminated and the tantalum wire is relatively flat. The diameter of the bent tantalum wire is greater than 3 meters. During the winding process, the surface of the tantalum wire is smooth, without scratches and pollution, and there is no disorder of the wire, with clear levels. The gap between the tantalum wires is appropriate, and the tantalum wire is not adhered after being wound and annealed.

[0098] Comparative Example 1

[0099] The difference between this comparative example and Example 1 is that the angle between the generatrix of the lower cylinder and the vertical line of the bottom surface of the rotating drum is 5°, and the angle between the generatrix of the upper cylinder and the vertical line of the bottom surface of the rotating drum is also 5°. The rest of the device and the process parameters of the take-up method are completely the same.

[0100] The surface of the tantalum wire in this comparative example is bright under naked eyes, and no oil stains are found when wiping with white cloth. After straightening, the internal stress of the tantalum wire is eliminated and the tantalum wire is relatively flat. The diameter of the bent tantalum wire is greater than 3 meters. During the winding process, the surface of the tantalum wire is smooth, without scratches and pollution. Since the taper angles of the lower cylinder and the upper cylinder are both large, the tantalum wire slides upward during winding, but the initial diameters of the tantalum wire coils are the same. When the tantalum wire coils gradually move from the lower cylinder to the upper cylinder, the surface of the rotating drum does not have enough friction to support the tantalum wire coils due to the relatively small diameter of the upper cylinder and the relatively large diameter of the tantalum wire coils. As the number of coils increases, the tantalum wire coils in the upper cylinder sometimes fall to the lower cylinder, and the tantalum wire coils in the upper cylinder are relatively loose, which easily causes disorder of the wire.

[0101] Comparative Example 2

[0102] The difference between this comparative example and Example 1 is that the angle between the generatrix of the lower cylinder and the vertical line of the bottom surface of the rotating drum is 1.5°, and the angle between the generatrix of the upper cylinder and the vertical line of the bottom surface of the rotating drum is also 1.5°. The rest of the device and the process parameters of the take-up method are completely the same.

[0103] The surface of the tantalum wire in this comparative example is bright under naked eyes, and no oil stains are found when wiping with white cloth. After straightening, the internal stress of the tantalum wire is eliminated and the tantalum wire is relatively flat. The diameter of the bent tantalum wire is greater than 3 meters. During the winding process, the surface of the tantalum wire is smooth, without scratches and pollution. However, since the taper angles of the lower cylinder and the upper cylinder are equal, the upward movement of the tantalum wire during winding is not smooth, and the winding overlaps and the levels are unclear, which easily causes disorder of the wire.

[0104] Comparative Example 3

[0105] The difference between this comparative example and Example 1 is that the angle between the generatrix of the lower cylinder and the vertical line of the bottom surface of the rotating drum is 1.5°, and the angle between the generatrix of the upper cylinder and the vertical line of the bottom surface of the rotating drum is 3°. The rest of the device and the process parameters of the take-up method are completely the same.

[0106] The surface of the tantalum wire in the present comparative example is bright under naked eyes, and no oil stains are found when wiping with white cloth. There are few water stains on the surface. The internal stress of the tantalum wire is eliminated after straightening, and the tantalum wire is relatively flat. The diameter of the bent tantalum wire is greater than 3 meters. The surface of the tantalum wire is smooth and not scratched and contaminated during winding. The tantalum wire slips upward during winding. Because the taper angles of the lower cylinder and the upper cylinder are quite different, the tantalum wire slips upward during winding. The diameters of the tantalum wire coils are the same at the initial stage. When the tantalum wire coil is gradually moved from the lower cylinder to the upper cylinder, the diameter of the upper cylinder is smaller, and the diameter of the tantalum wire coil is relatively larger. There is not enough friction on the surface of the rotating drum to support it, and the tantalum wire coil on the upper cylinder is relatively loose, which easily causes the tantalum wire to be tangled.

[0107] Comparative Example 4

[0108] The present comparative example and Example 1 differ in that there is no transition chamfer between the lower cylinder and the upper cylinder of the rotating drum, and they are directly connected. The process parameters of the remaining devices and the winding method are completely the same.

There are few water stains on the surface. The internal stress of the tantalum wire is eliminated after straightening, and the tantalum wire is relatively flat. The diameter of the bent tantalum wire is greater than 3 meters. The surface of the tantalum wire is smooth and not scratched and contaminated during winding. The tantalum wire slips upward during winding. Because there is no transition chamfer to connect, the tantalum wire coil on the upper cylinder will fall to the lower cylinder as the number of turns increases, which easily causes the tantalum wire to be tangled.

[0110] Comparative Example 5

[0111] The present comparative example and Example 2 differ in that the transition between the bottom plate and the lower cylinder of the rotating drum is at a right angle. The process parameters of the remaining devices and the winding method are completely the same.

[0112] The surface of the tantalum wire in the present comparative example is bright under naked eyes, and no oil stains are found when wiping with white cloth. There are few water stains on the surface. The internal stress of the tantalum wire is eliminated after straightening, and the tantalum wire is relatively flat. The diameter of the bent tantalum wire is greater than 3 meters. The tantalum wire collides when it enters the rotating drum through the second wire guide roller after straightening. The friction after the collision can scratch the surface of the tantalum wire. The tantalum wire is wound and overlapped as soon as it enters the rotating drum, which makes the winding and winding process unable to proceed normally.

[0114] The present comparative example and Example 2 differ in that the outer surface of the rotating drum has no coating. The process parameters of the remaining devices and the winding method are completely the same.

During the winding process, the surface of the tantalum wire is scratched and contaminated due to the rust on the surface of the rotating drum. The upward movement of the tantalum wire during winding is not smooth, and the winding overlaps and the levels are unclear, which can easily cause tangled wires.
