[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.

No external heating is required; the material is softened by frictional heat and then continuously extruded from the die orifice after high-pressure forming.

[0003] Before entering the extrusion roller groove for continuous extrusion, the surface of the metal billet is usually contaminated. This contamination will mix into the extruded material during the continuous extrusion process, affecting the morphology and performance of the extruded product. Utility Model Content

Detailed Implementation

[0032] 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.

[0033] Combination Figure 1 , Figure 2 This utility model provides a water washing and cleaning device, including an annular nozzle 1, a support member 2, and a water tank 3.

[0034] An annular nozzle 1 is used for online spraying and washing of the billet passing through it. The annular nozzle 1 is mounted on a support member 2, which contains a water inlet pipe. The annular nozzle 1 is connected to the water inlet pipe, which circulates the cleaning fluid used to wash the billet. The support member 2 is located within a water tank 3, which has an inlet and an outlet on each side for the billet to pass through. The billet passes sequentially through the inlet, the annular nozzle 1, and the outlet. The water tank 3 collects the cleaning fluid.

[0035] Specifically, the annular nozzle 1 includes a hollow cavity through which the 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 and sweep the surface of the billet. The inner wall of the annular nozzle 1 can be circular, oval, or other shapes to accommodate conductive components of different shapes, such as aluminum rods and aluminum bars.

[0036] It is understood that in this embodiment, by setting an annular nozzle 1, the billet is cleaned online as it passes through the annular nozzle 1, removing stains from the surface of the billet. This avoids the impact of stains on the extruded product when the billet is continuously extruded to produce conductive parts in the next step.

[0037] 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 1 in this embodiment uses less water, saving cleaning fluid and reducing the risk of oxidation of metal billets.

[0038] Furthermore, there are two or more annular nozzles 1, and each annular nozzle 1 is arranged sequentially along the extension direction of the support member 2, thereby improving the cleaning effect.

[0039] Furthermore, the number of support members 2 includes two, with the two support members 2 arranged side by side, and each of the two support members 2 is provided with two or more annular nozzles 1.

[0040] For example, in a production line for producing armored conductive components, two armored blanks are conveyed to a continuous extrusion coating machine to form an annular armor layer that is then applied to the outside of the core material to obtain an armored conductive component. The armored conductive component production line can be equipped with two water washing and cleaning devices, each with a support member 2. The annular nozzles 1 on the support members 2 clean the two armored blanks respectively. Preferably, the armored conductive component production line can be equipped with only one water washing and cleaning device, which has two support members 2. The annular nozzles 1 on the two support members 2 clean the two armored blanks respectively, reducing the number of cleaning devices, reducing the production line floor space, and saving costs.

[0041] Furthermore, the support member 2 includes an upper support member and a lower support member arranged opposite each other along the radial direction of the blank. An annular nozzle is disposed between the upper and lower support members, and the annular nozzle 1 is connected to water inlet pipes within both the upper and lower support members. By synchronizing water supply to the upper and lower support members, cleaning efficiency is improved. Figure 2 Only the lower support member is shown as an example.

[0042] In some optional embodiments, the support 2 is an ultrasonic vibration support 2. For example, the ultrasonic vibration support 2 is configured with a vibrating body (such as a piezoelectric ceramic transducer) forming part of the flow channel. 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 billet.

[0043] In some alternative embodiments, refer to Figure 2 The inlet and / or outlet are equipped with a blower assembly 4. The blower assembly 4 at the inlet can pre-clean the billet by blowing it, and the blower assembly 4 at the outlet can dry the residual cleaning liquid on the billet.

[0044] In one specific embodiment, the water tank 3 is equipped with a partition (not shown in the figure), which divides the water tank 3 into a first zone and a second zone. The support member 2 is disposed on the first zone. The cleaning liquid after the billet is sprayed online by the annular nozzle 1 falls into the first zone. The partition is equipped with a filter screen. The cleaning liquid in the first zone is filtered and then enters the second zone. A water pump draws the cleaning liquid in the second zone and delivers it to the water inlet pipe in the support member 2. The cleaning liquid is then used to spray the billet online, completing the recycling of the cleaning liquid. A blower assembly 4 is provided at the inlet to pre-clean the billet, which can further reduce the degree of dirtiness of the cleaning liquid after spraying the billet and reduce the frequency of filter screen replacement.

[0045] Furthermore, the blowing assembly 4 includes a hollow ring body connected to the blowing mechanism. The inner wall of the hollow ring body is provided with a blowing port for blowing the surface of the billet. The blowing assembly 4 can also be a fan, a multi-nozzle array air knife, etc.

[0046] Reference Figures 3-5 This utility model embodiment also provides a conductive component production line, including a water washing and cleaning device 101 as described in any of the above embodiments.

[0047] Furthermore, following the water washing and cleaning device 101, there are also a continuous production device, an online cooling device 102, and a collection device 103 arranged in sequence.

[0048] Specifically, the continuous production apparatus is used to continuously produce conductive parts from cleaned billets. The continuous production apparatus includes a continuous extruder 205, an extrusion coating machine 306 or a continuous extrusion coating machine 404. 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 404 is used to produce armored conductive parts.

[0049] The online cooling device 102 cools down the continuously produced conductive parts, and the cooled conductive parts are collected by the collection device 103.

[0050] Specifically, the collection device 103 can be a winding device or an online sawing and collection device.

[0051] 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.

[0052] 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.

[0053] In some alternative embodiments, refer to Figure 3 The 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 collection device 103 arranged in sequence. The billet cleaning device 204 includes the water cleaning device 101 described in any of the above embodiments.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] In some alternative embodiments, refer to Figure 4 The conductive component production line is used to produce insulating conductive components. The conductive component production line includes a conductive core unwinding device 301, a front tension device 302, a conductive core straightening device 303, a conductive core cleaning device 304, a front preheating device 305, an extrusion coating machine 306, a rear heating device 307, an online cooling device 102, a rear tension device 308, and a collection device 103 arranged in sequence. The conductive core cleaning device 304 is any of the water washing devices 101 described in the above embodiments.

[0060] In this embodiment, the metal conductive core is unwound by the conductive core unwinding device 301, then straightened by the conductive core straightening device 303 to ensure flatness. After straightening, the metal conductive core is pulled by the front tension device 302 into the conductive core cleaning device 304 to clean its surface. After cleaning, the metal conductive core is preheated by the front preheating device 305 and then enters the extrusion coating machine 306 to be coated with an insulating layer. The rear heating device 307 reheats the insulating layer of the insulating conductive part, and then the insulating conductive part is collected after cooling. By setting the front preheating device 305, the metal conductive core preheated can be tightly bonded to the extruded high-temperature insulating layer; by setting the rear heating device 307 to reheat and soften the insulating layer, wrinkles are smoothed, making the surface of the insulating layer smooth and improving product yield; by setting the front tension device 302 and the rear tension device 308 to form a closed-loop tension control, the synchronization error of the linear speed before and after the metal conductive core is coated with the insulating layer is reduced, ensuring the concentricity of the metal conductive core during forward conveying and preventing the problem of uneven thickness caused by eccentricity of the coated insulating layer.

[0061] Specifically, the extrusion coating machine 306 is a commercially available extrusion coating machine 306 that includes components such as a hopper, screw, barrel, die head, and mold. The hopper is used to load the insulating plastic raw material. The screw, through rotation and propulsion, crushes, softens, melts, plasticizes, degasses, and compacts the plastic raw material within the barrel, continuously extruding the plasticized melt. The die head converts the rotating plastic melt into parallel linear motion, uniformly and smoothly guiding it into the die sleeve and applying the necessary molding pressure to the plastic. The mold includes an orifice and a core mold. The orifice forms the outer diameter of the insulating layer, and the core mold forms the inner diameter of the insulating layer. The core mold has a die hole in its center for the passage of a metal conductive core, thus allowing the extrusion coating machine 306 to coat the insulating layer onto the metal conductive core.

[0062] Furthermore, a detection device (not shown in the figure) is provided between the rear traction device 407 and the collection device 103. The detection device includes one or more of the following: an online power frequency spark test unit, a diameter measuring unit, a meter measuring unit, a visual inspection unit, and a thickness measuring unit. The online power frequency spark test unit tests whether the insulation layer of the insulating conductive component is leaking current. The diameter measuring unit detects the outer diameter of the insulation layer in real time through laser diffraction or CCD imaging. The meter measuring unit accurately measures the length of the insulating conductive component. The thickness measuring unit is used to measure the thickness of the insulation 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 insulation layer.

[0063] In some alternative embodiments, refer to Figure 5 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 401, two armored billet conveying units 402 arranged in parallel, and a continuous extrusion coating machine 404. The core material conveying unit 401 is used to transfer the core material to the continuous extrusion coating machine 404, and the armored billet conveying unit 402 is used to transfer the armored billet to the continuous extrusion coating machine 404.

[0064] The continuous extrusion coating machine 404 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 orifice, 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 orifice. 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. 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.

[0065] The core material conveying unit 401 includes a core material feeding device 4011, a core material traction device 4012, a core material straightening device 4013, and a core material cleaning device 4014 arranged in sequence. The core material cleaning device 4014 can be any of the water washing and cleaning devices 101 described in the above embodiments.

[0066] Specifically, the core material feeding device 4011 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 4012 is a traction machine that provides the power for the core material to move forward. The core material straightening device 4013 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 404.

[0067] The armored billet conveying unit 402 includes an armored billet feeding device 4021, an armored billet traction device 4022, an armored billet straightening device 4023, and an armored billet cleaning device 4024 arranged in sequence. The armored billet cleaning device 4024 can be any of the water washing and cleaning devices 101 described in the above embodiments.

[0068] Specifically, the armored billet feeding device 4021 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 4022 is a traction machine that provides the power for the armored billet to move forward. The armored billet straightening device 4023 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 404.

[0069] Furthermore, the conductive component production line also includes an integration device 403. Before the continuous extrusion coating machine 404 is installed, the integration device 403 includes multiple guide wheels, which guide the armored blank to the core material line.

[0070] Furthermore, the continuous extrusion coating machine 404 also includes an online cooling device 102, an online diameter reduction device 406, a rear traction device 407, and a collection device 103 arranged sequentially.

[0071] 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 406. Then it is pulled into the collection device 103 by the rear traction device 407 for collection.

[0072] 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.

[0073] 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 406. 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.

[0074] A rear traction device 407 is installed after the online diameter reduction device 406. The rear traction device 407 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.

[0075] Furthermore, the online diameter reduction device 406 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.

[0076] Furthermore, the online diameter reduction device 406 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 armor layer from overheating during the diameter reduction process, which could lead to a decrease in material strength and hardness.

[0077] 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.

[0078] 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 shoes. This eliminates the need for two extrusion rollers to extrude the two armored blanks, reducing the space occupied by the continuous extrusion coating machine 404 and saving costs.

[0079] Furthermore, a detection device (not shown in the figure) is provided between the rear traction device 407 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.

[0080] Furthermore, the conductive component production line also includes a self-adjusting guide device 405, which is disposed between the online cooling device 102 and the online diameter reduction device 406. The self-adjusting guide device 405 adjusts the conveying speed of the cooled armored conductive components.

[0081] Specifically, the self-adjusting guide device 405 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 405 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 405 before the online diameter reduction device 406 can ensure the smooth operation of the production line.

[0082] 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.
