Description

Technical Field

[0001] This utility model relates to the field of conductive component manufacturing technology, and more specifically, to an online sawing device and a conductive component production line. Background Technology

[0002] Conductive components are a significant portion of the cost of high-voltage connector harnesses in electric vehicles. They are primarily used to connect the battery pack and generator, as well as to charge the battery pack.

[0003] Current technology produces conductive components through continuous extrusion. In a continuous extruder, the extrusion rollers rotate forward under power. When the copper or aluminum rod blank to be extruded enters the groove of the extrusion roller, it is guided into the extrusion chamber formed by the extrusion rollers and the die cavity by the friction of the grooved rollers. Here, a plug prevents the extruded material from advancing further. Under the high pressure and high temperature generated by strong friction, an infinitely long copper or aluminum product is extruded. Currently, the infinitely long extruded product needs to be manually sawed, and automated and efficient online sawing cannot be achieved. The entire production process cannot achieve continuous production, resulting in low production efficiency and high costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned defects in the existing technology and provide an online sawing device and a conductive component production line to realize the continuous production of conductive components.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An online sawing device, comprising:

[0007] Conveyor drive mechanism;

[0008] A support mechanism is connected to the conveying drive mechanism, which drives the support mechanism to reciprocate along a first direction, the first direction being the conveying direction of the product to be sawed.

[0009] A clamping mechanism is disposed on the support mechanism and is used to clamp the product to be sawed;

[0010] A sawing mechanism is disposed on one side of the clamping mechanism along a second direction, and the sawing mechanism is used to saw the product to be sawed, wherein the second direction intersects with the first direction;

[0011] A telescopic drive mechanism is provided, which is connected to the sawing mechanism, and is used to drive the sawing mechanism to reciprocate along the second direction.

[0012] A conductive component production line includes a continuous production device, an online cooling device, a rear traction device, and the aforementioned online sawing device arranged sequentially. The conductive component blank is conveyed to the continuous production device to obtain a conductive component. The online cooling device is used to cool the conductive component. The rear traction device is used to traction the cooled conductive component. The online sawing device is used to saw the cooled conductive component.

[0013] The continuous production apparatus includes a continuous extruder, an extrusion coating machine, or a continuous extrusion coating machine. The continuous extruder is used to continuously extrude metal billets to obtain metal conductive parts. The extrusion coating machine extrudes an insulating layer and coats it onto the metal conductive parts to obtain insulating conductive parts. The continuous extrusion coating machine is used to continuously extrude armored billets to obtain an armor layer and coat it onto the metal conductive parts or insulating conductive parts to obtain armored conductive parts.

[0014] Implementing the embodiments of this utility model will have the following beneficial effects:

[0015] In this embodiment of the invention, the online sawing device includes a conveying drive mechanism, a support mechanism, a clamping mechanism, a sawing mechanism, and a telescopic drive mechanism. The clamping mechanism holds the product to be sawed, and the telescopic drive mechanism moves the sawing mechanism closer to the product for sawing. After sawing, the telescopic drive mechanism moves the sawing mechanism away from the product for retraction. The clamping mechanism, sawing mechanism, and telescopic drive mechanism are integrated into the support mechanism. During sawing, the conveying drive mechanism only needs to control the support mechanism, avoiding the conveying rate errors that can easily occur when controlling the clamping mechanism, sawing mechanism, and telescopic drive mechanism separately, which could lead to inaccurate cutting positions. The conveying drive mechanism drives the support mechanism to move synchronously with the product to be sawed, achieving online sawing and continuous production. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] Reference Figure 1 , Figure 2 This utility model provides an online sawing device 101, including: a conveying drive mechanism 1, a support mechanism 2, a clamping mechanism 3, a sawing mechanism 4, and a telescopic drive mechanism 5.

[0031] The support mechanism 2 is connected to the conveying drive mechanism 1, which drives the support mechanism 2 to reciprocate along the first direction X, where the first direction X is the conveying direction of the product to be sawed. The clamping mechanism 3 is mounted on the support mechanism 2 and is used to clamp the product to be sawed. The sawing mechanism 4 is mounted on one side of the clamping mechanism 3 along the second direction Y and is used to saw the product to be sawed. The second direction Y intersects with the first direction X. The telescopic drive mechanism 5 is connected to the sawing mechanism 4 and is used to drive the sawing mechanism 4 to reciprocate along the second direction Y.

[0032] Understandably, the clamping mechanism 3 clamps the product to be sawed, and the telescopic drive mechanism drives the sawing mechanism 4 to move closer to the product to be sawed for sawing. After sawing is completed, the telescopic drive mechanism drives the sawing mechanism 4 to move away from the product to be sawed for recycling.

[0033] In this embodiment, the clamping mechanism 3, sawing mechanism 4, and telescopic drive mechanism 5 are integrated onto the support mechanism 2. The conveying drive mechanism 1 drives the support mechanism 2 to move synchronously with the product to be sawed, realizing online sawing and continuous production. For example, the sawing device includes an inlet and an outlet. At the inlet, a clamping mechanism clamps the product to be sawed. The conveying drive mechanism 1 drives the support mechanism 2 to move towards the outlet. During the synchronous movement of the support mechanism 2 and the product to be sawed, the sawing mechanism 4 performs sawing. After sawing is completed, the conveying drive mechanism 1 drives the support mechanism 2 to move back towards the inlet to reset for the next sawing. During the sawing process, the conveying drive mechanism 1 only needs to control the support mechanism 2, avoiding the conveying rate errors that can easily occur when separately controlling the clamping mechanism 3, sawing mechanism 4, and telescopic drive mechanism 5, which could lead to inaccurate cutting positions.

[0034] Furthermore, the support mechanism 2 is a box, and the clamping mechanism 3, the sawing mechanism 4, and the telescopic drive mechanism 5 are all set inside the box. The side wall of the box, which is set opposite to each other along the first direction X, has a hollow area for the product to be sawed to pass through (not shown in the figure).

[0035] Furthermore, the sawing mechanism 4 includes a sawing power source 41 and a sawing head 42 connected to each other. The sawing power source 41 is used to drive the sawing head 42 to rotate and saw.

[0036] In some alternative embodiments, refer to Figure 2 The telescopic drive mechanism 5 includes a first slide rail 51 and a telescopic power source 52. The first slide rail 51 extends along the second direction Y and is mounted on the support mechanism 2. The sawing power source 41 is mounted on the first slide rail 51 and is slidably connected to the first slide rail 51. The telescopic power source 52 is connected to the sawing mechanism 4 and is used to drive the sawing mechanism 4 to reciprocate on the first slide rail 51.

[0037] Specifically, the telescopic power source 52 can be electrically driven, pneumatically driven, hydraulically driven, etc. Preferably, the telescopic power source 52 is an electric motor.

[0038] Preferably, there are two or more first slide rails 51, and each first slide rail 51 is arranged sequentially along the first direction X to improve the stability of the sawing power source 41 during movement.

[0039] In some alternative embodiments, refer to Figure 2 The clamping mechanism 3 includes a clamping component 31 and a clamping power source (not shown in the figure).

[0040] The clamping assembly 31 includes an upper clamping member 311 and a lower clamping member 312 disposed opposite each other along a third direction Z. The lower clamping member 312 is fixedly connected to the support mechanism 2. The product to be sawed is clamped between the upper clamping member 311 and the lower clamping member 312. The third direction Z intersects with the first direction X and the second direction Y. A clamping power source is connected to the upper clamping member 311 and is used to drive the upper clamping member 311 to reciprocate along the third direction Z.

[0041] Specifically, the clamping power source can be electric, pneumatic, hydraulic, etc. Preferably, the clamping power source is an electric motor.

[0042] Preferably, the clamping assembly 31 includes two clamping assemblies arranged sequentially along the first direction X, with a gap between the two clamping assemblies 31, through which the sawing head 42 enters to make cuts. By providing two clamping assemblies 31, the sawing head 42 cuts through the gap between the two clamping assemblies 31, thereby improving cutting accuracy.

[0043] In some alternative embodiments, refer to Figure 1 The conveying drive mechanism 1 includes a conveying power source 11, a transmission component 12, and a second slide rail 13.

[0044] The transmission assembly 12 is connected to the power source 11, and the support mechanism 2 is connected to the transmission assembly 12. The power source is used to rotate and drive the transmission assembly 12 to move linearly, and the transmission assembly 12 is used to drive the support mechanism 2 to reciprocate along the first direction X. The second slide rail 13 extends along the first direction X, and the support mechanism 2 is slidably connected to the second slide rail 13.

[0045] Specifically, the power source 11 can be electrically driven, pneumatically driven, hydraulically driven, etc., and the transmission component 12 is a lead screw and a nut sleeved on the lead screw. The lead screw is connected to the power source 11, and the support mechanism 2 is fixedly connected to the nut. Preferably, the power source 11 is a motor.

[0046] Preferably, there are two or more second slide rails 13, and each second slide rail 13 is arranged sequentially along the second direction Y to improve the stability of the support mechanism 2 during movement.

[0047] In some alternative embodiments, refer to Figure 1 The online sawing device 101 also includes a machine base 6, on which a conveying drive mechanism 1 is mounted. Limit sensors 61 and limit switches 62 are respectively provided at both ends of the machine base 6, which are arranged opposite each other along the second direction Y. When the limit sensor 61 senses the support mechanism 2, it controls the conveying power source 11 to stop through the limit switch 62 to prevent the support mechanism 2 from falling off the machine base 6.

[0048] Reference Figures 3-5 This utility model embodiment also provides a conductive component production line, including a continuous production device 102, an online cooling device 103, a rear traction device 104, and an online sawing device 101 as described in any of the above embodiments, arranged in sequence. The conductive component blank is conveyed to the continuous production device 102 to obtain the conductive component. The online cooling device 103 is used to cool the conductive component. The rear traction device 104 is used to pull the cooled conductive component. The online sawing device 101 is used to saw the cooled conductive component.

[0049] The continuous production apparatus 102 includes a continuous extruder 1021, an extrusion coating machine 1022 or a continuous extrusion coating machine 1023. The continuous extruder 1021 is used to continuously extrude metal billets to obtain metal conductive parts. The extrusion coating machine 1022 extrudes an insulating layer and coats it onto the metal conductive parts to obtain insulating conductive parts. The continuous extrusion coating machine 1023 is used to continuously extrude armored billets to obtain an armor layer and coat it onto the metal conductive parts or insulating conductive parts to obtain armored conductive parts.

[0050] In this embodiment, the conductive parts produced by the continuous production devices 102, such as the continuous extruder 1021, the extrusion coating machine 1022, and the continuous extrusion coating machine 1023, are cut online by the online sawing device 101 without stopping the machine, thus achieving continuous production.

[0051] Furthermore, referring to Figure 6 The conductive component production line also includes a collection device 105, which is located after the online sawing device 101. The collection device 105 includes a transfer platform 1051 and a collection frame 1052 arranged adjacent to each other along a second direction. A collection drive 1053 is provided on the transfer platform 1051, which pushes the sawn conductive component products to the collection frame 1052. A soft webbing is provided inside the collection frame 1052 to cushion the conductive component products as they fall into it.

[0052] In some alternative embodiments, refer to Figure 3 The continuous production apparatus 102 includes a billet traction device 202, a billet cleaning device 204 and a continuous extruder 1021 arranged in sequence.

[0053] It should be noted that the conductive component production line in this embodiment is used to produce metal conductive components. The conductive component production line includes a billet traction device 202, a billet straightening device 203, a billet cleaning device 204, a continuous extruder 1021, an online cooling device 103, a rear traction device 104, and an online sawing device 101 arranged in sequence. Furthermore, it also includes a billet unwinding device 201, which is arranged in front of the billet traction device 202.

[0054] The billet unwinding device 201 unwinds the metal billet. After being straightened by the straightening device, the metal billet is pulled into the cleaning device to clean its surface. The cleaned metal billet is then extruded by the continuous pressing device to obtain a conductive metal component. The conductive metal component is cooled and then pulled into the online sawing device 101 for sawing. By setting up the billet cleaning device 204, the surface of the billet is cleaned before extrusion, avoiding impurities from affecting the conductivity.

[0055] Specifically, in this embodiment, the billet traction device 202 is a traction machine, and the continuous extrusion press 1021 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 billet cleaning device 204 includes one or more of a first cleaning unit, a second cleaning unit, and a third cleaning unit. The first cleaning unit is used to roughen the surface of the metal billet, the second cleaning unit is used to smooth the surface of the metal billet, and the third cleaning unit is used to clean the surface of the metal billet.

[0057] Specifically, the first cleaning unit includes a first rotating brush and a second rotating brush located on both sides of the metal billet. The first and second rotating brushes rotate around the metal billet, and can also rotate on their own axes of rotation. The first cleaning unit is used to roughen the surface of the metal billet, removing not only stubborn stains but also surface oxide scale.

[0058] The second cleaning unit includes a rotating disk, brush holders, and brushes. The metal billet passes through the center of the rotating disk, which rotates around it. Two or more brush holders are evenly distributed and fixed around the circumference of the rotating disk, rotating with it. The brushes are fixed to the brush holders and perform a rotating brushing motion on the metal billet. This second cleaning unit smooths the surface of the metal billet, removing powder and solid particles. The smoothing process also prevents solid particles from accumulating in the pores or crevices of the rough surface, thus avoiding impact on the quality of the extruded material.

[0059] The third cleaning unit includes a water tank with an inlet for the metal billet to enter and an outlet for it to exit on its front and rear sides, respectively. Multiple nozzles are arranged inside the water tank along the direction of the metal billet's extension, and these nozzles spray water to clean the surface of the metal billet. Preferably, the third cleaning unit is an ultrasonic water washing unit.

[0060] Preferably, the billet cleaning device 204 further includes a blowing unit, which removes powder or water by blowing after the first cleaning unit, second cleaning unit, or third cleaning unit is provided. When the billet cleaning device 204 includes two or more of the first cleaning unit, second cleaning unit, and third cleaning unit, a blowing unit can be provided after each cleaning unit.

[0061] Preferably, the billet cleaning device 204 further includes a heating unit, which is located after the blowing unit. After the metal billet is heated, the metal plasticity is increased, the deformation resistance is reduced, thereby reducing the hardness requirements of the extrusion die material, increasing the deformation uniformity to facilitate filling the extrusion die and cavity, increasing the extrusion temperature to increase the solid solubility, and putting the material in a high-energy state, which is beneficial for the subsequent aging to fully precipitate the second phase. When the billet cleaning device 204 is equipped with a third cleaning unit, the heating unit is set to further remove the moisture on the surface of the metal billet, so as to avoid the undried moisture being carried into the extruder, where the moisture evaporates into gas and causes defects such as bulging.

[0062] Furthermore, a detection device (not shown in the figure) is provided between the rear traction device 104 and the online sawing device 101. The detection device includes one or more of the following: a diameter measuring unit, a meter counting unit, and a visual inspection unit. The diameter measuring unit detects the outer diameter of the metal conductive part in real time through laser diffraction or CCD imaging; the meter counting unit accurately measures the length of the armored conductive part; and the visual inspection unit is used to detect surface defects of the metal conductive part.

[0063] In some alternative embodiments, refer to Figure 4 The continuous production device 102 includes a front tension mechanism 1024, a front preheating mechanism 1025, an extrusion coating machine 1022 and a rear heating mechanism 1026 arranged in sequence. The front tension mechanism 1024 is used to pull the metal conductive parts, the front preheating mechanism 1025 is used to heat the metal conductive parts, and the rear heating mechanism 1026 heats the insulating conductive parts.

[0064] Furthermore, the conductive component production line also includes a conductive core unwinding device 301 and a conductive core cleaning device 303.

[0065] It should be noted that the conductive component production line in this embodiment is used to produce insulating conductive components. The conductive component production line includes a conductive core unwinding device 301, a front tension mechanism 1024, a conductive core straightening device 302, a conductive core cleaning device 303, a front preheating mechanism 1025, an extrusion coating machine 1022, a rear heating mechanism 1026, an online cooling device 103, a rear traction device 104, and an online sawing device 101 arranged in sequence.

[0066] In this embodiment, the metal conductive component is unwound by the conductive core unwinding device 301, and then straightened by the conductive core straightening device 302 to ensure flatness. After straightening, the metal conductive component is pulled by the first tension mechanism into the conductive core cleaning device 303 to clean its surface. After cleaning, the metal conductive component is preheated by the preheating device and then enters the extrusion coating machine 1022 to be coated with an insulating layer. The rear heating device reheats the insulating layer of the insulating conductive component. Then, the insulating conductive component is cooled and pulled into the online sawing device 101 for sawing. By setting the preheating device, the metal conductive core preheated by the preheating device can be tightly bonded to the extruded high-temperature insulating layer. By setting the rear heating mechanism 1026 to reheat and soften the insulating layer, wrinkles are smoothed, and the surface of the insulating layer is made smooth, improving the product yield. By setting the front tension mechanism 1024 and the rear traction device 104 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.

[0067] Specifically, the conductive core cleaning device 303 includes one or more of a first cleaning unit, a second cleaning unit, and a third cleaning unit, as well as a blowing unit. The first cleaning unit, the second cleaning unit, the third cleaning unit, and the blowing unit have the same structure as those in the blank cleaning device 204, and will not be described in detail here.

[0068] The extrusion coating machine 1022 is a commercially available extrusion coating machine 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 at its center for a metal conductive core to pass through, thus allowing the extrusion coating machine 1022 to coat the insulating layer onto the metal conductive core.

[0069] Furthermore, a detection device (not shown in the figure) is provided between the rear traction device 104 and the online sawing device 101. 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.

[0070] In some alternative embodiments, refer to Figure 5 The conductive component production line also includes an online diameter reduction device 401. The continuous production device 102 is a continuous extrusion coating machine 1023. The continuous extrusion coating machine 1023, online cooling device 103, online diameter reduction device 401, and rear traction device 104 are arranged in sequence. The online diameter reduction device 401 is used to reduce the diameter of the armor layer and bond the armor layer to the core material.

[0071] The continuous extrusion coating machine 1023 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.

[0072] It should be noted that in this embodiment, the conductive component production line is used to produce armored conductive components. The armored blank and the core material are conveyed to the continuous extrusion coating machine 1023. The continuous extrusion coating machine 1023 continuously extrudes the armored blank to obtain an armored conductive component with an armored layer covering the core material and the core material suspended in the armored layer. After cooling, the armored conductive component is made to adhere the armored layer to the core material by the online diameter reduction device 401, and then is pulled into the online sawing device 101 for sawing.

[0073] In this embodiment, the core material enters the continuous extrusion coating machine 1023 through the through hole in the center of the inner die. The armored blank is continuously extruded into the extrusion cavity through the extrusion wheel groove, and then enters the annular extrusion cavity through the die opening. The annular extrusion cavity yields a closed annular armored layer. The core material and the armored blank enter the continuous extrusion coating machine 1023 simultaneously, and the armored layer is obtained through continuous extrusion, thus achieving continuous production.

[0074] 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 chamber. 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 chamber and the outlet of the through hole, and the outlet of the annular extrusion chamber 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, which avoids the armor layer contacting the core material and burning the insulating layer.

[0075] After the armor layer and the core material are cooled together in the online cooling device, the armor layer is then reduced in diameter by the online diameter reduction device 401. 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.

[0076] A rear traction device 104 is installed after the online diameter reduction device 401. The rear traction device 104 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.

[0077] Furthermore, the online diameter reduction device 401 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.

[0078] Furthermore, the online diameter reduction device 401 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.

[0079] 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.

[0080] 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 1023 and saving costs.

[0081] Furthermore, the conductive component production line also includes a core material conveying device 402 and two parallel armored billet conveying devices 403. The core material conveying device 402 is used to transfer the core material to the continuous extrusion coating machine 1023, and the armored billet conveying device 403 is used to transfer the armored billet to the continuous extrusion coating machine 1023.

[0082] Furthermore, the armored billet conveying device 403 includes an armored billet feeding mechanism 4031, an armored billet traction mechanism 4032, an armored billet straightening mechanism 4033, and an armored billet cleaning mechanism 4034 arranged in sequence.

[0083] Among them, the armored billet feeding mechanism 4031 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 to ensure the continuity of material supply and the accuracy of speed synchronization at the front end of the production line.

[0084] The armored billet traction mechanism 4032 is a traction machine that provides the power for the armored billet to move forward.

[0085] The armor blank straightening mechanism 4033 is a straightening machine, which includes a transverse straightening device and a longitudinal straightening device to ensure the straightness of the armor blank before it enters the continuous extrusion coating machine 1023.

[0086] The structure of the armored billet cleaning mechanism 4034 is the same as that of the metal billet cleaning device 204, and will not be described again here.

[0087] Furthermore, the conductive component production line also includes a guiding device 404, which is located after the armored blank cleaning mechanism 4034 and guides the armored blank to the core material line.

[0088] Furthermore, the core material conveying device 402 includes a core material feeding mechanism 4021, a core material traction mechanism 4022, a core material straightening mechanism 4023, and a core material cleaning mechanism 4024 arranged in sequence.

[0089] The core material feeding mechanism 4021 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 to ensure the continuity of material supply and the accuracy of speed synchronization at the front end of the production line.

[0090] The core material traction mechanism 4022 is a traction machine that provides the power for the core material to move forward.

[0091] The core material straightening mechanism 4023 is a straightening machine, which includes a transverse straightening device and a longitudinal straightening device to ensure the straightness of the core material before it enters the continuous extrusion coating machine 1023.

[0092] When the core material is a metallic conductive component, the core material cleaning mechanism 4024 may include one or more of a first cleaning unit, a second cleaning unit, and a third cleaning unit, as well as a blowing unit. The first cleaning unit, the second cleaning unit, the third cleaning unit, and the blowing unit have the same structure as those in the blank cleaning device 204, and will not be described again here. When the core material is an insulating conductive component, the core material cleaning mechanism 4024 is only provided with a third cleaning unit.

[0093] Furthermore, a detection device (not shown in the figure) is provided between the rear traction device 104 and the online sawing device 101. 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.

[0094] Furthermore, the conductive component production line also includes a self-adjusting guide device 405, which is disposed between the online cooling device and the online diameter reduction device 401. The self-adjusting guide device 405 adjusts the conveying speed of the cooled armored conductive components.

[0095] 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 401 can ensure the smooth operation of the production line.

[0096] Furthermore, a detection device (not shown in the figure) is provided between the rear traction device 104 and the online sawing device 101. 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.

[0097] 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.
