[0002] Continuous metal extrusion technology is a process that utilizes friction and mechanical pressure to achieve the plastic forming of metals. It enables the efficient production of metal products through continuous feeding and dynamic extrusion.

Detailed Implementation

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Combination Figures 1-3This utility model embodiment provides an online cleaning device 101, including a rotary brush cleaning unit 1 and a brush cleaning unit 2 arranged in sequence.

[0044] The brush cleaning unit 1 includes a base 11, a brush assembly 12, and a brush drive mechanism (not shown in the figure). The base 11 has a first channel for the metal billet to pass through; the brush assembly 12 is disposed on the base 11 and includes two or more rotating brushes 121 arranged around the metal billet; the brush drive mechanism is connected to the brush assembly 12 and is used to drive the brush assembly 12 to rotate, so that the brush assembly 12 can perform coarse brushing on the surface of the metal billet.

[0045] The brush cleaning unit 2 includes a rotating mechanism 21, a brush assembly 22, and a rotating drive mechanism (not shown in the figure). The rotating mechanism 21 has a second channel for the metal blank to pass through; the brush assembly 22 is disposed on the rotating mechanism 21, and the brush assembly 22 includes two or more brush heads 221 arranged around the metal blank; the rotating drive mechanism is connected to the brush assembly 22, and the rotating drive mechanism is used to drive the rotating mechanism 21 and the brush assembly 22 to rotate, and the brush assembly 22 rotates to perform fine brushing on the surface of the metal blank.

[0046] It should be noted that metal billets can be extruded through a continuous extrusion press to prepare metal conductive components. Metal billets can also be extruded through a continuous extrusion coating press to obtain an armor layer that coats the core material to prepare armored conductive components. If the surface of the metal billet has stains, oxide layers, etc., continuous extrusion will affect the product performance.

[0047] In this embodiment, the metal billet is cleaned online by sequentially passing through the first channel and the second channel. During the passage of the metal billet through the first channel, the rotating brush drive mechanism drives the rotating brush 121 to rotate. The rotating brush 121 is a metal brush, and its rotation provides coarse friction to the metal billet, primarily roughening its surface and removing stains and / or oxide scale. During the passage of the metal billet through the second channel, the rotating drive mechanism drives the brush assembly 22 to rotate via a rotating component. Each brush head 221 further polishes the surface of the metal billet and removes large pieces of waste material polished by the brush assembly 12. The rotation of each brush head 221 allows for 360° cleaning of the metal billet surface, resulting in a smooth surface. This embodiment ensures the cleanliness of the metal billet surface through a dual-stage cleaning process using the brush cleaning unit 1 and the brush cleaning unit 2.

[0048] The brush drive mechanism and the rotary drive mechanism are independently controlled. The brush cleaning unit 1 and / or brush cleaning unit 2 can be activated according to the degree of dirt on the surface of the metal billet. The online cleaning device is flexibly adjustable according to actual production.

[0049] In some alternative embodiments, refer to Figure 2The brush cleaning unit 1 also includes a first housing 13. The base 11 and the brush assembly 12 are disposed within the first housing 13, and a first material collection mechanism (not shown in the figure) is provided at the bottom of the first housing 13. Specifically, a waste collection funnel is provided at the bottom of the first housing 13, and the bottom of the funnel is connected to the first material collection mechanism. The top of the first housing 13 also includes a top cover to seal the rotating brush 121 and prevent waste from polluting the air.

[0050] Furthermore, the brush drive mechanism includes a first power source, which can be driven by an electric motor, pneumatically, or hydraulically.

[0051] In one specific embodiment, a first power source is disposed inside the first housing 13, and two first power sources are directly connected to the rotating brush 121 to drive the rotating brush 121 to rotate.

[0052] In another specific embodiment, the brush drive mechanism further includes a first transmission component, which connects the first power source and the brush assembly 12. The first transmission component can be a belt, a gear set, etc. For example, the first power source is located outside the housing, and the rotating brush 121 is rotatably connected to the base 11 via a connecting shaft. A belt is sleeved on the connecting shaft of the two rotating brushes 121 and the drive shaft of the first power source. One first power source drives two rotating brushes 121 to rotate simultaneously via the belt, reducing the number of first power sources.

[0053] In some alternative embodiments, refer to Figure 3 The number of brush components 22 is two or more, and each brush component 22 is arranged sequentially along the transport direction of the metal blank. For example, Figure 3 There are two brush components 22 and two rotating mechanisms 21. Each brush component 22 is connected to one rotating mechanism 21 to improve cleaning efficiency.

[0054] Furthermore, the brush cleaning unit 2 also includes a second housing 23, within which the rotating mechanism 21 and the brush assembly 22 are disposed. A second material collection mechanism (not shown in the figure) is located at the bottom of the second housing 23. By providing the second material collection mechanism, waste is collected, and the sealed second housing 23 prevents waste from polluting the air.

[0055] Furthermore, the rotating mechanism 21 includes a connecting seat 211 and a rotating disk 212. A supporting partition is provided inside the second housing 23, and the connecting seat 211 is disposed on the supporting partition. The connecting seat 211 is rotatably connected to the rotating disk 212, which is connected to a rotating drive mechanism. A second channel passes through the connecting seat 211 and the rotating disk 212. Each rotating mechanism 21 includes two or more connected rotating disks 212, and each rotating disk 212 is equipped with a brush assembly 22. By providing two or more rotating disks 212, the rotating mechanism 21 increases the number of brush heads 221, thereby improving cleaning efficiency.

[0056] Furthermore, the brush drive mechanism includes a second power source, which can be driven by an electric motor, pneumatically, or hydraulically.

[0057] In one specific embodiment, the second power source is disposed inside the second housing 23. The second power source is directly connected to the rotating disk 212 to drive the rotating disk 212 to rotate. In this embodiment, the drive shaft of the second power source is a hollow shaft, which allows metal billets to pass through.

[0058] In another specific embodiment, the rotary drive mechanism further includes a second transmission component, which connects the second power source and the rotating disk 212. The second transmission component can be a belt, a gear set, etc. For example, the second housing 23 is provided with two brush assemblies 22, the second power source is located outside the second housing 23, and a belt is sleeved on the rotating disk 212 of the two brush assemblies 22 and the drive shaft of the second power source. One second power source drives the two rotating disks 212 to rotate simultaneously through the belt, reducing the number of second power sources.

[0059] In some alternative embodiments, the online cleaning device 101 also includes a blower assembly 4.

[0060] Optionally, the blower assembly 4 is disposed between the wheel brush cleaning unit 1 and the brush cleaning unit 2, and / or the blower assembly 4 is disposed after the brush cleaning unit 2.

[0061] In one specific embodiment, reference is made to Figure 3 The blowing assembly 4 includes a ring body located at the outlet of the brush cleaning unit 2. The metal blank passes through the middle of the ring body, which has an internal cavity connected to the blowing device. The inner wall of the ring body has a blowing port connected to the cavity. The blowing port blows away the grinding waste from the surface of the metal blank, further improving the surface cleanliness of the metal blank. The blowing assembly 4 can also be a fan, a multi-nozzle array air knife, etc.

[0062] In some alternative embodiments, refer to Figure 4 The online cleaning device 101 also includes a guide component 5, which is disposed in front of the wheel brush cleaning unit 1, and / or, disposed between the wheel brush cleaning unit 1 and the brush cleaning unit 2, and / or, disposed after the brush cleaning unit 2.

[0063] In one specific embodiment, the guide assembly 5 includes a mounting base 51, a slider 52, a first guide wheel 53, and a second guide wheel 54. The first guide wheel 53 is fixed to the mounting base 51, and the second guide wheel 54 is fixed to the slider 52. The slider 52 is disposed on the mounting base 51. The first guide wheel 53 and the second guide wheel 54 are disposed opposite to each other. The slider 52 drives the second guide wheel 54 to move closer to or away from the first guide wheel 53, and the metal billet passes between the first guide wheel 53 and the second guide wheel 54.

[0064] In this embodiment, the guide component 5 ensures the coaxial transmission of the metal billet, avoiding excessive axial offset, which would affect the concentricity of the metal billet transmission and the cleaning effect.

[0065] In some alternative embodiments, refer to Figure 5 The online cleaning device 101 also includes a water cleaning unit 3, which is disposed after the brush cleaning unit 2.

[0066] The water cleaning unit 3 includes an annular nozzle 31, a support member 32, and a water tank 33. The annular nozzle 31 is used for online spraying and washing of the metal billet passing through it. The annular nozzle 31 is mounted on the support member 32, which has an inlet pipe connected to it. The inlet pipe is used to circulate the cleaning fluid for washing the metal billet. The support member 32 is mounted on the water tank 33, which has an inlet and an outlet on both sides for the metal billet to pass through. The metal billet passes through the inlet, the annular nozzle 31, and the outlet in sequence. The water tank 33 is used to collect the cleaning fluid.

[0067] Specifically, the annular nozzle 31 includes a hollow cavity through which the metal billet passes. The hollow cavity is connected to a water inlet pipe, and the inner wall of the hollow cavity is provided with a water spray nozzle to spray water onto the surface of the metal billet.

[0068] It is understood that in this embodiment, by setting an annular nozzle 31, the metal billet is cleaned online as it passes through the annular nozzle 31, removing stains from the surface of the metal billet. This avoids the impact of stains on the extruded product when the metal billet is continuously extruded to produce conductive parts in the next step.

[0069] Traditional water tank immersion cleaning methods result in a lot of residual liquid on the surface of metal billets, slow drying, and a high risk of oxidation. The annular nozzle 31 in this embodiment uses less water, saving cleaning fluid and reducing the risk of oxidation of metal billets.

[0070] Furthermore, the inlet and / or outlet are also provided with a blower assembly 4. The blower assembly 4 at the inlet can pre-clean the metal billet by blowing it, and the blower assembly 4 at the outlet can dry the residual cleaning liquid on the metal billet.

[0071] In one specific embodiment, the water tank 33 is equipped with a partition (not shown in the figure), which divides the water tank 33 into a first zone and a second zone. The support member 32 is disposed on the first zone. The cleaning solution after the metal billet is sprayed online by the annular nozzle 31 falls into the first zone. The partition is equipped with a filter screen, and the cleaning solution in the first zone is filtered and enters the second zone. A water pump draws the cleaning solution from the second zone and delivers it to the water inlet pipe in the support member 32. The cleaning solution is then used to spray the metal billet online, completing the recycling of the cleaning solution. A blower assembly is installed at the inlet to pre-clean the metal billet, which can further reduce the degree of dirtiness of the cleaning solution after spraying the metal billet and reduce the frequency of filter screen replacement.

[0072] In some alternative embodiments, refer to Figure 5 The number of annular nozzles 31 is two or more, and each annular nozzle 31 is arranged sequentially along the extension direction of the support member 32, thereby improving the cleaning effect.

[0073] In one specific embodiment, the number of support members 32 includes two, the two support members 32 are arranged side by side, and each of the two support members 32 is provided with two or more annular nozzles 31.

[0074] For example, in a production line for armored conductive components, two armored blanks are conveyed to a continuous extrusion coating machine to form an annular armor layer covering the core material, thus obtaining an armored conductive component. The armored conductive component production line can be equipped with two online cleaning devices 101, each with a support member 32. The annular nozzles 31 on the support members 32 clean the two armored blanks respectively. Preferably, the armored conductive component production line can be equipped with only one online cleaning device 101, which has two support members 32. The annular nozzles 31 on the two support members 32 clean the two armored blanks respectively, reducing the number of cleaning devices, reducing the production line floor space, and saving costs.

[0075] In one specific embodiment, the number of support members 32 includes two, which are arranged opposite to each other along the radial direction of the metal billet. An annular nozzle is disposed between the two support members and is connected to the water inlet pipes in the two support members respectively to improve the water inlet efficiency.

[0076] In one specific embodiment, the support member 32 includes an upper support member and a lower support member arranged opposite to each other along the radial direction of the metal billet, and the annular nozzle 31 is connected to the water inlet pipes in the upper and lower support members respectively. By synchronizing water supply to the upper and lower support members, the cleaning efficiency is improved. Figure 5 Only the lower support member is shown as an example.

[0077] Furthermore, the support 32 is an ultrasonic vibration support 32. For example, the ultrasonic vibration support 32 is part of the flow channel by setting a vibrating body (such as a piezoelectric ceramic transducer). When the cleaning fluid flows over the surface of the vibrating body, ultrasonic energy is transferred to the cleaning fluid, generating a cavitation effect (the formation and collapse of tiny bubbles in the liquid), thereby enhancing the penetration and impact of the cleaning fluid and improving the cleaning effect on the oxide scale of the metal billet.

[0078] Reference Figure 6 , Figure 7 This utility model embodiment also provides a conductive component production line, including an online cleaning device 101 as described in any of the above embodiments.

[0079] Furthermore, following the online cleaning device 101 are a continuous production device, an online cooling device 102, and a collection device 103 arranged in sequence.

[0080] Specifically, the continuous production apparatus is used to continuously produce conductive parts from cleaned blanks. The continuous production apparatus includes a continuous extruder 205, an extrusion coating machine 306 or a continuous extrusion coating machine 304. The continuous extruder 205 is used to produce metal conductive parts, the extrusion coating machine 306 is used to produce insulated conductive parts, and the continuous extrusion coating machine 304 is used to produce armored conductive parts.

[0081] The online cooling device 102 cools down the continuously produced conductive parts, and the cooled conductive parts are collected by the collection device 103.

[0082] Specifically, the collection device 103 can be a winding device or an online sawing and collection device.

[0083] The collecting device includes a guide wheel assembly unit and a winding unit. The guide wheel assembly unit includes multiple sets of guide wheels, through which the conductive component is guided into the winding unit for winding, ensuring smooth winding. The winding unit includes a reel and a reel lateral displacement drive, which drives the reel to move back and forth in a lateral direction perpendicular to the direction of movement of the conductive component to wind up the wire. Preferably, the collecting mechanism also includes a refractory paper unwinding reel, through which the refractory paper is unwound and guided by the guide wheels to the reel, so that the refractory paper is placed on the conductive component and wound up synchronously.

[0084] The online sawing and collection device includes a sawing machine, a drive mechanism, and a collection mechanism. The drive mechanism drives the sawing machine to move in the direction of the conductive component. During the movement, the sawing machine completes the cutting of the conductive component to a quantitative length, and the collection mechanism collects the cut conductive component.

[0085] In some alternative embodiments, refer to Figure 6The conductive component production line is used to produce metal conductive components. The conductive component production line includes a billet unwinding device 201, a billet traction device 202, a billet straightening device 203, a billet cleaning device 204, a continuous extruder 205, an online cooling device 102, and a collecting device 103 arranged in sequence. The billet cleaning device 204 includes the online cleaning device 101 described in any of the above embodiments.

[0086] The billet unwinding device 201 unwinds the metal billet, and the billet traction device 202 pulls the metal billet through the billet straightening device 203 for straightening. The metal billet then enters the billet cleaning device 204 to clean its surface. The cleaned metal billet enters the continuous extruder 205 to be extruded to obtain a conductive metal component. The conductive metal component is then collected after cooling. Cleaning the surface of the billet before continuous extrusion prevents impurities from affecting the conductivity.

[0087] Specifically, in this embodiment, the billet traction device 202 is a traction machine, and the continuous extrusion press 205 is a commercially available continuous extrusion press including components such as an extrusion roller, a compaction roller, an extrusion shoe, a plug, and an extrusion die. The extrusion roller has grooves on its circumference to accommodate and transport the metal billet to be extruded. The compaction roller is located on the feed side of the extrusion roller and is used for preliminary compaction and guidance of the metal billet. The extrusion shoe cooperates with the extrusion roller to form an extrusion cavity, and a groove sealing block is installed on the extrusion shoe to seal the concave grooves of the extrusion roller. The plug is fixed to the outlet end of the extrusion cavity to prevent the metal billet from continuing to move forward, forcing it to flow out of the extrusion die. The extrusion die is fixed to the extrusion shoe and may include a circular bar die or a flat strip die, etc., to prepare conductive parts of different shapes.

[0088] Furthermore, the conductive component production line also includes a heating device (not shown in the figure). This heating device is located after the billet cleaning device 204. Heating the metal billet increases its plasticity, reduces its deformation resistance, thereby lowering the hardness requirements of the extrusion die material, increases deformation uniformity to facilitate filling the extrusion die and cavity, and increases the extrusion temperature to increase solid solubility, placing the material in a high-energy state. Subsequent aging facilitates the precipitation of the second phase. The heating device further removes surface moisture from the metal billet, preventing undried moisture from being carried into the extruder, where it evaporates into gas, causing defects such as bulging. The heating device can specifically be an oven, a hot air blower, etc.

[0089] Furthermore, a detection device (not shown in the figure) is included before the collection device 103. The detection device includes one or more of a diameter measuring unit, a meter measuring unit, and a visual inspection unit. The diameter measuring unit detects the outer diameter of the metal conductive component in real time through laser diffraction or CCD imaging; the meter measuring unit accurately measures the length of the armored conductive component; and the visual inspection unit is used to detect surface defects of the metal conductive component.

[0090] Furthermore, an aging device 206 is included after the collection device 103. For example, when the metal conductive component is a pure aluminum conductive component, the pure aluminum conductive component can be directly collected by the collection device 103; when the metal conductive component is an aluminum alloy conductive component, the collected aluminum alloy conductive component needs to be further aged by the aging device 206. The alloying elements are dissolved into the aluminum matrix under continuous extrusion high temperature, and a supersaturated solid solution is formed after rapid cooling. However, the supersaturated state is unstable, and fine and dispersed second phases will precipitate during the aging treatment. These precipitated phases can hinder dislocation movement and improve strength.

[0091] In some alternative embodiments, refer to Figure 7 In this embodiment, the conductive component production line is used to produce armored conductive components. The conductive component production line includes a core material conveying unit 301, two armored billet conveying units 302 arranged in parallel, and a continuous extrusion coating machine 304. The core material conveying unit 301 is used to transfer the core material to the continuous extrusion coating machine 304, and the armored billet conveying unit 302 is used to transfer the armored billet to the continuous extrusion coating machine 304.

[0092] The continuous extrusion coating machine 304 includes an extrusion roller, an extrusion roller shoe, and an extrusion die. The extrusion roller has an extrusion roller groove, and the extrusion roller and the extrusion roller shoe form an extrusion cavity. The extrusion roller shoe has a die opening, and the extrusion roller shoe is connected to the extrusion die. The extrusion die includes an inner die and an outer die fitted outside the inner die. The center of the inner die has a through hole for the core material to pass through. An annular extrusion cavity is provided between the outer die and the inner die. The inlet of the annular extrusion cavity is connected to the die opening, and there is a gap between the outlet of the annular extrusion cavity and the outlet of the through hole. The outlet of the annular extrusion cavity is parallel to the outlet of the through hole. The armored blank is conveyed to the extrusion roller groove, enters the extrusion cavity, is continuously extruded, and passes through the annular extrusion cavity to obtain a closed annular armored layer. The core material is suspended in the closed annular armored layer to obtain the armored conductive component precursor.

[0093] The core material conveying unit 301 includes a core material feeding device 3011, a core material traction device 3012, a core material straightening device 3013, and a core material cleaning device 3014 arranged in sequence.

[0094] Specifically, the core material feeding device 3011 includes a wire reel and a guide wheel assembly. The feeding device continuously and stably releases the core material and adjusts the feeding tension through the guide wheel assembly, ensuring continuous feeding and speed synchronization accuracy at the front end of the production line. The core material traction device 3012 is a traction machine that provides the power for the core material to move forward. The core material straightening device 3013 is a straightening machine, including a transverse straightening device and a longitudinal straightening device, ensuring the straightness of the core material before it enters the continuous extrusion coating machine 304. The core material cleaning device 3014 can be any of the water cleaning units 3 described in the above embodiments.

[0095] The armored billet conveying unit 302 includes an armored billet feeding device 3021, an armored billet traction device 3022, an armored billet straightening device 3023, and an armored billet cleaning device 3024 arranged in sequence. The armored billet cleaning device 3024 can be any of the online cleaning devices 101 described in the above embodiments.

[0096] Specifically, the armored billet feeding device 3021 includes a wire reel and a guide wheel assembly. The feeding device continuously and stably releases the armored billet and adjusts the feeding tension through the guide wheel assembly, ensuring continuous feeding and speed synchronization accuracy at the front end of the production line. The armored billet traction device 3022 is a traction machine that provides the power for the armored billet to move forward. The armored billet straightening device 3023 is a straightening machine, including a transverse straightening device and a longitudinal straightening device, ensuring the straightness of the armored billet before it enters the continuous extrusion coating machine 304.

[0097] Furthermore, the conductive component production line also includes an integration device 303. Before the continuous extrusion coating machine 304 is installed, the integration device 303 includes multiple guide wheels, which guide the armored blank to the core material line.

[0098] Furthermore, the continuous extrusion coating machine 304 also includes an online cooling device 102, an online diameter reduction device 306, a rear traction device 307, and a collection device 103 arranged sequentially.

[0099] The core material suspended in the armor layer is cooled by the online cooling device 102 and then the armor layer is made to adhere to the core material by the online diameter reduction device 306. Then it is pulled into the collection device 103 by the rear traction device 307 for collection.

[0100] In this embodiment, the core material can be a metal conductive component or an insulating conductive component. When the core material is an insulating conductive component, the temperature is high when the armor layer is extruded through the annular extrusion cavity. If it is directly wrapped on the insulating layer, it is easy to burn the insulating layer. In this embodiment, there is a gap between the outlet of the annular extrusion cavity and the outlet of the through hole, and the outlet of the annular extrusion cavity is parallel to the outlet of the through hole. After the armor layer is extruded, the armor layer does not completely adhere to the core material. The core material is suspended in the closed annular armor layer, avoiding the armor layer from contacting the core material and burning the insulating layer.

[0101] After the armor layer and the core material are cooled together in the online cooling device 102, the armor layer is then reduced in diameter by the online diameter reduction device 306. After the armor layer is reduced in diameter, the thickness remains basically unchanged. The reduction in the outer diameter of the armor layer is converted into an increase in the length of the armor layer. After the outer diameter of the armor layer is reduced, the armor layer adheres to the insulation layer.

[0102] A rear traction device 307 is installed after the online diameter reduction device 306. The rear traction device 307 tightens the core material and continuously conveys the core material forward to ensure that the core material moves in a straight line and ensures the concentricity of the core material.

[0103] Furthermore, the online diameter reduction device 306 includes a diameter reduction mold, through which the armor layer is reduced in diameter and then bonded to the core material. The diameter reduction mold has a diameter reduction channel for the armored conductive component to pass through. The diameter reduction channel includes an inlet and an outlet arranged opposite each other. Along the direction from the inlet to the outlet, the inner diameter of the diameter reduction channel gradually decreases, ensuring the armor layer is tightly bonded to the core material. Preferably, there are two or more diameter reduction molds, and along the transmission direction of the armored conductive component, the inner diameter of the diameter reduction channel of each diameter reduction mold gradually decreases. Since heat is generated during the diameter reduction process of the armor layer, by setting two or more diameter reduction molds and performing multiple diameter reduction passes, excessively high temperatures that could lead to grain growth and a decrease in material strength and hardness are avoided.

[0104] Furthermore, the online diameter reduction device 306 includes a cooling water tank, with the diameter reduction mold located inside the cooling water tank. Coolant is placed inside the cooling water tank to cool the diameter reduction mold. By setting up a cooling water tank, the coolant cools the armored conductive components, further preventing the material strength and hardness from decreasing due to excessively high temperatures during the diameter reduction process of the armor layer.

[0105] Furthermore, two extrusion wheel grooves are provided in parallel on the extrusion wheel, and two die openings are provided on the extrusion wheel shoe. The two die openings are respectively connected to the annular extrusion cavity. The two armored billets enter one extrusion wheel groove for continuous extrusion and are extruded into the annular extrusion cavity through one die opening respectively.

[0106] Understandably, compared to a single armored blank, two armored blanks are more likely to form a closed ring after extrusion, reducing the product defect rate. The extrusion roller has two parallel extrusion grooves. Two armored blanks are extruded on one extrusion roller and then enter the annular extrusion chamber through the dies on the extrusion shoe. This eliminates the need for two extrusion rollers to extrude the two armored blanks, reducing the space occupied by the continuous extrusion coating machine 304 and saving costs.

[0107] Furthermore, a detection device (not shown in the figure) is provided between the rear traction device 307 and the collection device 103. The detection device includes one or more of the following: a diameter measuring unit, a meter measuring unit, a thickness measuring unit, and a visual inspection unit. The diameter measuring unit detects the outer diameter of the armor layer in real time through laser diffraction or CCD imaging; the meter measuring unit accurately measures the length of the armor conductive parts; the thickness measuring unit is used to measure the thickness of the armor layer, and its detection source can be ultrasound, X-ray, laser, current, etc.; the visual inspection unit is used to detect surface defects of the armor layer.

[0108] Furthermore, the conductive component production line also includes a self-adjusting guide device 305, which is disposed between the online cooling device 102 and the online diameter reduction device 306. The self-adjusting guide device 305 adjusts the conveying speed of the cooled armored conductive components.

[0109] Specifically, the self-adjusting guide device 305 includes a support frame, a lever arm, and a guide wheel. One end of the lever arm is rotatably connected to the support frame, and the other end of the lever arm is fixed to the guide wheel. The guide wheel has gravity, and under its own weight, it tends to move downwards. When the armored conductive wire is loose, the guide wheel moves downwards; when the armored conductive wire is tight, the guide wheel moves upwards. The self-adjusting guide device 305 then automatically adjusts the transmission speed according to the conveying speed of the armored conductive component. The resistance of the diameter reduction die is relatively large, which will affect the transmission speed of the armored conductive component. Therefore, setting up the self-adjusting guide device 305 before the online diameter reduction device 306 can ensure the smooth operation of the production line.

[0110] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
