Description

Technical Field

[0002] Copper-clad steel bimetallic composite material, also known as copper-coated steel, is a composite conductor made by processing copper and steel through a special process. This conductor combines the high strength, excellent elasticity, high thermal resistance, and high magnetic permeability of steel with the good electrical conductivity and excellent corrosion resistance of copper, and is widely used in the electrical and electronic fields.

[0003] Currently, there are three methods for producing copper-clad steel in China: electroplating, cladding, and horizontal continuous casting cladding. Among them, horizontal continuous casting cladding is more commonly used. Its principle is as follows: a cleaned steel core is passed horizontally through the molten copper in the copper melting furnace, and a certain thickness of copper is continuously cast at the exit through a horizontally installed crystallizer.

[0004] While horizontal continuous casting and cladding methods can solve the problems of thin copper layers in copper-clad steel produced by electroplating and poor adhesion in copper-clad steel produced by cladding, existing copper-clad steel production lines lack auxiliary devices for detecting, limiting, and alarming the dimensions of the workpieces during production.

[0016] The technical solution provided by this invention has the following advantages: 1.

[0017] This copper-clad steel production line features a traction structure that enables it to transport workpieces under external force. A straightening mechanism allows the workpieces to rotate, straightening any defects during rotation. A swing amplitude detection mechanism monitors the swing amplitude of the workpieces, allowing operators to promptly confirm whether to proceed to the next process, thus controlling production costs. A grinding mechanism polishes the surface of the workpieces until their surface finish meets the requirements of subsequent processes. Because the workpiece undergoes the aforementioned straightening mechanism, swing detection mechanism, grinding mechanism, and two-dimensional fine-tuning mechanism, the cross-sectional dimensions of the workpiece along the traction direction can be made more precise, which is beneficial to improving the coaxiality of the copper layer during copper plating, thereby ensuring the uniformity of the copper layer.

In addition, a heating mechanism is set up between the two-dimensional fine-tuning mechanism and the copper plating mechanism, and the heating mechanism is electrically connected to an external switch to preheat the workpiece before it enters the copper plating mechanism. The copper plating mechanism is also set up to perform the copper plating operation on the preheated workpiece. This not only enables the copper-clad steel production line to have the ability to plating copper, but also makes the performance of the finished copper-clad steel superior.

[0018] 2. The copper-clad steel production line provided by the present invention includes a straightening mechanism comprising: a rotating straightening component, the rotating straightening component having a rotating seat and at least one straightening ring, the straightening ring being disposed within the rotating seat, and the straightening ring having a straightening hole that allows the workpiece to be processed to pass through, the rotating seat being adapted to drive the straightening ring to rotate.

[0019] This copper-clad steel production line, with its straightening holes, restricts the workpiece at every point after it passes through them, thus allowing for effective rotational straightening during rotation.

[0020] 3. The copper-clad steel production line provided by the present invention further includes: at least one set of vertical straightening components, disposed at the feed inlet of the rotating straightening components. The vertical straightening components have a vertical mounting base and at least one set of vertical straightening rollers, the vertical straightening rollers being arranged in layers along the height direction between the side walls of the vertical mounting base, and the vertical rollers being suitable for rolling the upper and lower sides of the workpiece along the height direction.

[0021] This copper-clad steel production line, with its vertical straightening components, can straighten the workpiece in the vertical direction, which helps improve the vertical coating effect of the copper layer in the subsequent copper cladding process.

[0022] 4. The copper-clad steel production line provided by the present invention further includes: at least one set of horizontal straightening components, which are disposed at the discharge port of the rotating straightening components. The horizontal straightening components have a horizontal mounting base and at least one set of horizontal straightening rollers. The horizontal straightening rollers are spaced apart on the horizontal mounting base in the horizontal direction. The horizontal straightening rollers are suitable for rolling the left and right sides of the workpiece to be processed in the height direction.

[0023] This copper-clad steel production line, by setting up horizontal straightening components, can straighten the workpiece in the horizontal direction, which is beneficial to improving the horizontal coating effect of the copper layer in the subsequent copper cladding process.

[0024] 5. The copper-clad steel production line provided by the present invention includes a swing detection mechanism comprising: a first base, a rod body, a display element, and an alarm structure. The first base is located at the outlet of the rotating straightening component; the rod body is mounted on the first base and is adapted to fit against the workpiece to be processed; the display element is coated on the rod body and has a detection function to detect if the workpiece falls due to its swing during transport; the alarm structure is located on the rod body and near the end of the display element along the direction of gravity; the alarm structure has a detection function to detect if the workpiece is in contact with the display element.

[0025] This copper-clad steel production line features a display element coated on the outside of the rod body. During the conveying of the workpiece, the workpiece adheres to the rod body. When the workpiece swings, the display element rubs off due to the swing, allowing the swing amplitude of the workpiece to be observed on the rod body. This structure is simple, easy to operate, and facilitates the observation of the swing amplitude by technicians. Furthermore, an alarm structure is included. When the swing amplitude of the workpiece exceeds the range of the display element, it will trigger an alarm, making it easy for technicians to observe whether the swing amplitude of the workpiece exceeds the preset range.

[0026] 6. The copper-clad steel production line provided by the present invention includes a grinding mechanism comprising: a second base, a first grinding component, and a second grinding component. The second base has a second mounting hole adapted to mount a workpiece. The first grinding component is mounted at one end of the second base and includes a first grinding element and a second grinding element, the axis connecting the first grinding element and the second grinding element being a first connecting line.

[0027] This copper-clad steel production line uses a structure where the projections of the lines connecting the axes of the grinding components on the two grinding mechanisms onto the machine frame axis are perpendicular to each other.

[0029] This copper-clad steel production line, by setting up a first platform and a second platform, and setting at least one pair of support rollers on the second platform, enables the workpiece to move along the height direction and along the traction direction when passing through the guide channel, thus reducing the labor intensity of manual operation.

[0030] 8. The copper-clad steel production line provided by the present invention includes a copper cladding mechanism comprising a furnace, the furnace comprising: a first furnace chamber, a second furnace chamber, and a third furnace chamber, the first furnace chamber being provided with a first heating device for melting materials; the second furnace chamber being connected to the first furnace chamber via a first graphite connector; the third furnace chamber being connected to the second furnace chamber via a second graphite connector, and the third furnace chamber being provided with a second heating device for heat preservation of the molten liquid; wherein, the first graphite connector and the second graphite connector are respectively disposed at both ends of the bottom of the second furnace chamber along the height direction.

[0031] This copper-clad steel production line has a second furnace chamber that separates the first and third furnace chambers. The first graphite connector and the second graphite connector are respectively located at the two ends of the bottom of the second furnace chamber along the height direction. This prevents the new material molten in the first furnace chamber from directly entering the third furnace chamber and impacting the molten liquid in the third furnace chamber, which helps to ensure the stability of the temperature and pressure of the molten liquid in the third furnace chamber.

[0032] 9. The copper-clad steel production line provided by the present invention includes a crystallizer assembly adapted to separate the furnace from the outside environment. The crystallizer assembly comprises a first crystallizer and a second crystallizer. The first crystallizer is disposed at the inlet of the furnace, and the second crystallizer is disposed at the outlet of the furnace. The copper cladding mechanism further includes a gas sealing component disposed at the inlet of the furnace, adapted to isolate the furnace from external gases.

[0033] This copper-clad steel production line has a structure where the first crystallizer is located at the feed inlet and the second crystallizer is located at the discharge outlet. This ensures that the molten copper in the furnace does not enter the outside environment, thus saving production costs during the production of the parts to be processed. In addition, by setting a gas sealing device at the feed inlet of the furnace, the interior of the furnace can be isolated from the outside air, which helps to ensure better uniformity of the copper layer after cladding.

Detailed Implementation

[0036] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] Example 1 This embodiment provides a copper-clad steel production line, such as Figures 1 to 14 As shown, it includes: a traction mechanism adapted to traction the workpiece to be processed, and the following components arranged sequentially along the driving direction of the traction mechanism: a straightening mechanism 2, a swing amplitude detection mechanism 3, a polishing mechanism 4, a two-dimensional fine adjustment mechanism 5, a heating mechanism 8, and a copper plating mechanism 6. The system includes: a straightening mechanism 2 with a mounting cavity suitable for inserting the workpiece, the mounting cavity having a corresponding rotational motion state relative to the workpiece; a swing amplitude detection mechanism 3 suitable for detecting the swing amplitude of the workpiece during transmission; a grinding mechanism 4 with at least one grinding component suitable for the workpiece; a two-dimensional fine-tuning mechanism 5 with a support component for supporting the workpiece, the two-dimensional fine-tuning mechanism 5 being able to drive the support component to move horizontally and vertically in a plane perpendicular to the trajectory of the workpiece; a heating mechanism 8 disposed between the two-dimensional fine-tuning mechanism 5 and the copper plating mechanism 6, the heating mechanism 8 having a heating component with a heating cavity through which the workpiece is inserted, the heating component being electrically connected to an external switch; and a copper plating mechanism 6 having a furnace and a crystallizer assembly, the crystallizer assembly being inserted into the furnace, the crystallizer assembly being suitable for forming a uniform copper layer covering the outer surface of the workpiece. In this embodiment, the heating mechanism 8 preheats the workpiece, heating it to 1000°C before it enters the copper plating mechanism 6 for copper plating.

[0041] like Figure 2 As shown, the copper-clad steel production line provided in this embodiment includes a straightening mechanism comprising a horizontal straightening component 23, a rotary straightening component 21, and a vertical straightening component 22 arranged sequentially to straighten the workpiece penetrating through it in different directions. The rotary straightening component 21 includes a rotary seat 211 and multiple straightening rings 212 spaced apart along the axial direction of the rotary seat 211. One side of each straightening ring 212 engages with the rotary seat 211 for modular installation. To facilitate the passage of the workpiece, each straightening ring 212 has a straightening hole with a diameter slightly larger than that of the workpiece. To facilitate adjustment of the bending position on the workpiece, the rotary seat 211 has adjusting plates 215 on both radially sides, corresponding to the straightening rings 212. Each adjusting plate 215 has a through hole allowing an adjusting rod to pass through. The adjusting rod passes through the through hole and abuts against the outer side of the straightening ring 212. Specifically, the adjusting rod is a screw, and the through hole of the adjusting plate 215 is an internally threaded hole adapted to the screw. To facilitate the entry and exit of the workpiece, the rotating seat 211 has an inlet 213 and an outlet 214, both of which are conical openings. In this copper-clad steel production line, by setting a straightening ring 212, the workpiece is uniformly restricted at each point after passing through the straightening ring 212, thus allowing for effective rotational straightening during rotation. Furthermore, by setting a vertical straightening component, the workpiece can be straightened vertically, and by setting a horizontal straightening component, it can be straightened horizontally. This facilitates effective control of the coaxiality of the copper layer in the subsequent copper cladding process, thereby ensuring the uniformity of the copper layer.

[0042] like Figure 1 As shown, the copper-clad steel production line provided in this embodiment further includes a straightening mechanism 2 comprising four sets of vertical straightening components 22 and at least one set of horizontal straightening components 23. In this embodiment, the rotating straightening components 21, vertical straightening components 22, and horizontal straightening components are arranged alternately. Each vertical straightening component 22 has a vertical mounting base and at least one set of vertical straightening rollers. The vertical straightening rollers are arranged in layers along the height direction between the side walls of the vertical mounting base, and are suitable for rolling the upper and lower sides of the workpiece along the height direction. Each horizontal straightening component 23 has a horizontal mounting base and at least one set of horizontal straightening rollers. The horizontal straightening rollers are arranged alternately along the horizontal direction on the horizontal mounting base, and are suitable for rolling the left and right sides of the workpiece along the height direction.

[0043] The copper-clad steel production line provided in this embodiment also includes a condenser. The workpiece to be processed extending from the conveying mechanism passes sequentially through the straightening mechanism 2, the swing amplitude detection mechanism 3 (mentioned below), and the condenser, wherein there is a certain distance between the straightening mechanism 2, the swing amplitude detection mechanism 3, and the condenser.

[0044] like Figure 1 and Figure 3As shown, the copper-clad steel production line provided in this embodiment also includes a swing amplitude detection mechanism 3, comprising a first base 31, a rod body 32, and a display element. The rod body 32 is vertically mounted on the first base 31 and is in contact with the workpiece to be processed. The display element is coated on the outer wall of the rod body 32, and the display element has a detection function to detect when the workpiece to be processed falls due to the swing of the workpiece during transport. For example, in this embodiment, the rod body 32 is not specifically limited. To conform to reality, the rod body 32 adopts a frame structure in this embodiment. In other embodiments, the rod body 32 can also be set as a cylindrical structure. The display element is not specifically limited. To conform to reality, the display element is coal powder in this embodiment. In other embodiments, the display element can also be lime powder, paint, etc. The workpiece to be processed is not specifically limited. To conform to reality, the workpiece to be processed in this embodiment is steel wire. Therefore, in this embodiment, by coating the display element on the outside of the rod body 32, the workpiece is attached to the rod body 32 during the traction process. When the workpiece swings, the display element will be rubbed off by the swing of the workpiece, so the swing amplitude of the workpiece can be observed on the rod body 32. This structure is simple, easy to operate, and easy for technicians to observe the swing amplitude of the workpiece. In addition, by setting an alarm structure, when the swing amplitude of the workpiece exceeds the range of the display element, it will abut against the alarm structure, making it easy for technicians to observe whether the swing amplitude of the workpiece exceeds the preset range.

[0045] The copper-clad steel production line provided in this embodiment also includes an alarm structure installed on the rod body 32. The alarm structure is located on the rod body 32 near the lower end coated with pulverized coal and has a detection state for detecting contact between the workpiece and the coating. The alarm structure includes a swing rod 33 rotatably mounted on a first mounting hole in the rod body 32. The swing rod 33 is flush with the end of the coated pulverized coal. In the detection state, during the swing of the workpiece, if the swing amplitude exceeds a set limit, the swing rod 33 will rotate in the first mounting hole under the drive of the workpiece. The alarm structure also includes a detection element, which, in the detection state, detects the swing angle of the swing rod 33. This mechanism is simple in construction, easy to operate, and allows technicians to easily observe whether the swing amplitude of the workpiece exceeds a preset range.

[0046] The working principle of the swing amplitude detection mechanism 3 is as follows: Coal powder is coated on the outside of the rod body 32. The area of ​​the coal powder coating on the rod body 32 is the area of ​​the swing plane of the workpiece projected onto the rod body 32 along the transmission direction perpendicular to the workpiece. During the production traction process of the workpiece, since the workpiece is in contact with the rod body 32, when the workpiece swings under the driving force of the production line and its own weight, the coal powder coated on the rod body 32 will be rubbed off by the swing of the workpiece, thus forming a bright area on the rod body 32. The swing amplitude of the workpiece can be observed from this. This structure is simple, easy to operate, and easy for technicians to observe the swing amplitude of the workpiece on the production line.

[0047] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the copper-clad steel production line provided in this embodiment includes a grinding mechanism 4 comprising a second base 41, grinding components 42, and a driving component. The second base 41 has a second mounting hole 411 suitable for the workpiece to be processed to pass through. Two grinding components 42 are mounted on both sides of the second mounting hole 411 on the second base 41, and the center of the grinding component 42 and the center of the second mounting hole 411 are arranged on the same axis. The driving component is mounted on the second base 41, and the driving end of the driving component is connected to the grinding component 42 to drive the workpiece to rotate, which is suitable for providing driving force to the grinding component 42. For example, the second base 41 is not specifically limited; to conform to reality, the second base 41 in this embodiment is set to be circular, and the second mounting hole 411 is opened at the center of the circular second base 41. The grinding component 42 is not specifically limited; to conform to reality, the grinding component 42 in this embodiment is a flap wheel. The driving component is not specifically limited; to conform to reality, the driving component in this embodiment is a drive motor. The workpiece to be processed is not specifically limited; to conform to reality, the workpiece to be processed in this embodiment is a steel wire produced in the horizontal continuous casting production system. For example, in this embodiment, the polishing assembly includes a first polishing assembly and a second polishing assembly. Specifically, the first polishing assembly is installed at one end of the second base 41 and includes a first polishing element and a second polishing element. The axis connecting the first polishing element and the second polishing element is a first connecting line. The second polishing assembly is disposed at the other end of the second base 41 relative to the first polishing assembly. The second polishing assembly includes a third polishing element and a fourth polishing element. The axis connecting the third polishing element and the fourth polishing element is a second connecting line, and the second connecting line is spatially perpendicular to the first connecting line.

[0048] The grinding assembly 42, which is installed on the second base 41, is driven by the driving component to grind the workpiece that passes through the second mounting hole 411 of the second base 41. The structure is simple and easy to operate, which reduces the labor intensity of manual grinding, improves the efficiency of work, and can also improve the quality of the workpiece.

[0049] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the copper-clad steel production line provided in this embodiment has two mounting brackets 43 on the second base 41. The mounting brackets 43 are respectively installed between the second base 41 and the mounting end of the drive component, located on both sides of the second mounting hole 411. The mounting brackets 43 are provided with a drive assembly consisting of a first gear 34 and a second gear 35. The drive component drives the first gear 34 to rotate, and the second gear 35 meshes with the first gear 34. The flap wheel is connected to the second gear 35. An adjusting component 36 is installed on the second base 41, with one end connected to the mounting bracket 43. When grinding workpieces of different sizes, the adjusting component 46 can be adjusted to move the mounting bracket 43 closer to or further away from the second mounting hole 411, thereby adapting the contact between the flap wheel and the workpiece. This facilitates grinding of workpieces of different sizes, is easy to operate, reduces the labor intensity of manual grinding, improves work efficiency, and also improves the quality of the produced workpieces.

[0050] like Figure 1 and Figure 7 As shown, the copper-clad steel production line provided in this embodiment includes a two-dimensional fine-tuning mechanism 5 comprising a third base 51, a first platform 52 slidably connected to the third base 51, the first platform 52 being able to move relative to the third base 51 in a vertical direction under drive, a second platform 53 slidably connected to the first platform 52, the second platform 53 being able to move relative to the first platform 52 in a horizontal direction under drive, and a support roller fixed on the second platform 53, thereby being able to move synchronously with the first platform 52 and the second platform 53.

[0051] like Figure 7 As shown, in the copper-clad steel production line provided in this embodiment, the third base 51 is provided with a first driving member 54 suitable for driving the first platform 52 to move, and the first platform 52 is provided with a second driving member 55 suitable for driving the second platform 53. The first driving member 54 and the second driving member 55 are preferably driven by a cylinder. As an alternative implementation, the first driving member 54 and the second driving member 55 can also be driven by an electric push rod or a screw.

[0052] like Figure 7As shown, in the copper-clad steel production line provided in this embodiment, the support rollers on the second platform 53 include two oppositely arranged rollers 56. A guide channel for passing through the workpiece is formed between the two rollers 56. Here, the two rollers 56 are spaced apart along the height direction. The roller 56 located relatively lower supports the workpiece, while the roller 56 located relatively upper provides auxiliary guidance. As an alternative implementation, the two rollers 56 can also be arranged horizontally. Furthermore, the distance between the two rollers 56 is adjustable. Specifically, a support frame is fixed on the second platform 53, and the two rollers 56 are mounted on the support frame. The support frame has two symmetrically arranged strip grooves 57 extending along the line connecting the two rollers 56. The roller 56 located relatively upper is fastened to the strip groove 57 by bolts. The position of the roller 56 in the strip groove 57 is adjusted by adjusting the bolts, thereby adjusting the distance between the two rollers 56. As an alternative implementation, one roller 56 can be fixedly connected to a linear drive cylinder, and the distance between the two rollers 56 can be adjusted by the cylinder's operation. By making the distance between the two rollers 56 supporting the roller adjustable, it can accommodate parts of different diameters to be coated or processed, thereby expanding the applicability of the two-dimensional fine-tuning mechanism 5.

[0053] Working principle of the two-dimensional fine-tuning mechanism: When the workpiece is pulled onto the two-dimensional fine-tuning mechanism 5, it is supported by the support rollers and conveyed to the inlet of the furnace 1. The positions of the first platform 52 and the second platform 53 are adjusted so that the workpiece is coaxial with the inlet of the furnace 1. The workpiece is continuously supported by the two rollers 56. The workpiece product after the copper coating process in the furnace 1 is supported by the two-dimensional fine-tuning mechanism 5 after the outlet. The two-dimensional fine-tuning mechanism 5 before the inlet, the inlet of the furnace 1, the outlet of the furnace 1, and the two-dimensional fine-tuning mechanism 5 after the outlet are all on the same axis, thereby effectively improving the uniformity of the coating of the workpiece.

[0054] like Figure 1 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the copper-clad steel production line provided in this embodiment includes a copper cladding mechanism: a furnace. The furnace has a first furnace chamber 611, a second furnace chamber 612, and a third furnace chamber 613 connected in sequence. The first furnace chamber is provided with a first heating device for melting materials, and the third furnace chamber 613 is provided with a second heating device for keeping the molten liquid warm. The third furnace chamber 613 is provided with an inlet and an outlet for the product to be clad, which are arranged opposite to each other. A first crystallizer 625 for passing the product to be clad is connected to the outlet for the product to be clad.

[0055] Here, by setting up a second furnace chamber 612 to separate the first furnace chamber 611 and the third furnace chamber 613, the newly melted material from the first furnace chamber 611 is prevented from directly entering the third furnace chamber 613 and impacting the molten material in the third furnace chamber 613. This helps to ensure the stability of the temperature and pressure of the molten material in the third furnace chamber 613. The crystallizer is directly connected to the third furnace chamber 613. Since the third furnace chamber 613 maintains the stability of the molten material used to coat the product at all times, the coating effect of the crystallizer can also be guaranteed.

[0056] It should be noted that, for the aforementioned coated products, this embodiment illustrates the production of copper-clad steel bimetallic materials. The production process involves: a clean steel core being horizontally passed through molten copper in a copper melting furnace, and copper of a certain thickness being continuously cast at the outlet using a horizontally installed crystallizer. As an alternative implementation, this furnace can also be used to produce other coated products formed using a hot-dip galvanizing process.

[0057] like Figure 8 As shown, in this embodiment, the first furnace chamber 611, the second furnace chamber 612, and the third furnace chamber 613 are lined with refractory bricks 614, and ramming mix 615 is filled between the furnace chamber and the refractory bricks 614 to provide good insulation and support. Here, the ramming mix 615 can be a readily available and mature refractory unshaped ramming mix 615 material. Furthermore, another layer of refractory bricks 614 is laid between the outer shell of the furnace body and the ramming mix 615. The refractory bricks 614 located on the inner side of the furnace chamber are in direct contact with the molten copper; a layer of asbestos is laid outside the refractory bricks 614 located on the outer side to enhance the insulation effect of the furnace body. Here, the direction outward from the center of the furnace body is the outer direction in this embodiment, and the direction from the outer shell of the furnace body towards the center is the inner direction in this embodiment.

[0058] In this embodiment, the tops of the first furnace chamber 611, the second furnace chamber 612, and the third furnace chamber 613 are all equipped with furnace covers to facilitate the addition of solid copper material or deoxidizing material into the furnace chamber. A first heating device is connected below the first furnace chamber 611 and includes an annular molten groove 617. The annular molten groove 617 is connected to the first furnace chamber 611 through a straight molten groove 618 to facilitate heat exchange between the molten solution and the copper material located in the first furnace chamber 611.

[0059] Still Figure 8 As shown, an electromagnetic induction component is provided in the annular molten groove 617. The electromagnetic induction component includes an iron core 619, an insulating plate 621, and a water jacket 622 arranged sequentially from the inside to the outside. A copper coil 623 passes through the center of the iron core 619 and surrounds the molten groove on both sides. After the copper coil 623 is energized, it is affected by electromagnetic induction, and the molten solution rotates clockwise in the annular molten groove 617 and exchanges heat with the copper material in the first furnace chamber 611.

[0060] Furthermore, the second heating device is connected below the third furnace chamber 613. The second heating device can be configured similarly to the first heating device to heat or maintain the temperature of the molten copper within the third furnace chamber 613. As an alternative implementation, the second heating device can also employ other heating methods, as long as they ensure that the molten copper within the third furnace chamber 613 remains within a stable temperature range.

[0061] like Figure 8 As shown, in this embodiment, the first furnace chamber 611 and the second furnace chamber 612 are connected by a first graphite connector 616, and the second furnace chamber 612 and the third furnace chamber 613 are connected by a second graphite connector 624. Using graphite connectors to connect the first furnace chamber 611, the second furnace chamber 612, and the third furnace chamber 613 can protect the molten copper inside the furnace from oxidation and can reduce copper oxide and cuprous oxide, thereby ensuring the coating effect of the steel core. Here, the first graphite connector 616 and the second graphite connector 624 are respectively located at the bottom of the second furnace chamber 612 to avoid the addition of oxygen-degrading impurities floating on the molten copper.

[0062] In this embodiment, combustible deoxygenating materials, such as charcoal, are placed in the second furnace chamber 612. Setting up the second furnace chamber 612 can prevent the deoxygenating materials placed in the first furnace chamber 611 from interfering with the convection effect of the copper liquid during the heating process. As an alternative implementation, deoxygenating materials can be placed in the first furnace chamber 611, the second furnace chamber 612 and the third furnace chamber 613 to enhance the deoxygenation effect in the furnace chamber.

[0063] like Figures 8 to 11 As shown, in this embodiment, the first crystallizer 625 is connected to the second support member 626. The second support member 626 is a brick structure with a central perforation. The first crystallizer 625 is inserted into the perforation of the second support member 626 and then secured. Specifically, the second support member 626 is embedded in the refractory bricks 614 lining the third furnace chamber 613. Since ramming material 615 is filled between the two layers of refractory bricks 614 in the furnace chamber, the outer wall of the second support member 626 is pressed and held together by the ramming material 615, and the two ends of the second support member 626 are pressed and held together by the refractory bricks 614, thereby forming a fixed state for the second support member 626 in the third furnace chamber 613.

[0064] like Figures 8 to 11As shown, in this embodiment, the first crystallizer 625 and the second support member 626 are connected by a sleeve 631. One end of the sleeve 631 is engaged with the outer boss of the first crystallizer 625. The sleeve 631 and the second support member 626 are interference-fitted, which fixes the first crystallizer 625 and the second support member 626 and prevents the first crystallizer 625 from moving axially inward or outward. Here, the part of the first crystallizer 625 used for the product outlet of the third furnace chamber 613 is fitted with an inner liner 632 to provide protection and heat preservation.

[0065] Based on the structure of the first crystallizer 625, in this embodiment, a second crystallizer 629 for passing through the product to be coated is connected to the inlet of the third furnace 613. The second crystallizer 629 is secured to the third support member 628, which is a brick structure with a central perforation. The second crystallizer 629 is inserted into the perforation of the third support member 628 and then secured. Specifically, the third support member 628 is embedded in the refractory bricks 614 lining the third furnace 613. Since ramming material 615 is filled between the two layers of refractory bricks 614 in the furnace, the outer wall of the third support member 628 is pressed and tightened by the ramming material 615, and the two ends of the third support member 628 are pressed and tightened by the refractory bricks 614, thereby forming a fixed state of the third support member 628 in the third furnace 613.

[0066] It should be noted that the fixing method between the second crystallizer 629 and the third support member 628 can be the same as the fixing method between the first crystallizer 625 and the second support member 626 described above. The second crystallizer 629 can further coat the steel core, thereby improving the uniformity and efficiency of copper coating on the steel core.

[0067] like Figures 8 to 11 As shown, in this embodiment, the second support member 626 and the third support member 628 are spaced apart by a constraint member 627. The constraint member 627 is a shaped brick with limiting steps 331 formed at both ends. Here, the opposite end faces of the second support member 626 and the third support member 628 are both right-angled surfaces. The limiting steps 331 on the shaped brick are respectively engaged with the two right-angled surfaces, so that the shaped brick abuts against the second support member 626 and the third support member 628 respectively. Since the shaped brick itself is a rigid brick body, the second support member 626 and the third support member 628 are constrained by the shaped brick after abutting, thereby preventing relative movement between the two and helping to ensure the fixed state of the first crystallizer 625 and the second crystallizer 629.

[0068] like Figure 1 , Figure 12 , Figure 13 and Figure 14As shown, in the copper-clad steel production line provided in this embodiment, any crystallizer in the copper cladding mechanism includes: a fixed sleeve 6254, a cooling pipe 6253 and a casting mold 6255 that are connected to the first through hole of the fixed sleeve 6254. The cooling pipe 6253 is provided with a channel that allows the steel wire 6262 to pass through, with a first end located in the first through hole and a connector 6258 sleeved on the second end.

[0069] like Figure 12 As shown, part of the casting mold 6255 is located within the first through hole of the fixing sleeve 6254, and another part extends to the outside of the first through hole. The casting mold 6255 has a second through hole that allows the steel wire 6262 to pass through, and a gap is reserved between the steel wire 6262 and the inner wall of the second through hole. In order to allow the molten copper in the copper melting furnace to cover the steel wire 6262 in the cooling pipe 6253, four casting holes 6256 are evenly spaced along the circumferential direction on the exposed side wall of the casting mold 6255. The casting holes 6256 are connected to the second through hole. To be suitable for the high-temperature environment in the copper melting furnace, the casting mold 6255 is made of graphite.

[0070] like Figure 12 As shown, it also includes a core-fixing mold 6257 disposed in the second through hole of the fixing sleeve 6254. The core-fixing mold 6257 has a core-fixing hole, and the core-fixing mold 6257 is clearance-fitted with the steel wire 6262 passing through the core-fixing mold 6257. The inner diameter of the core-fixing mold 6257 is the same as the inner diameter of the cooling pipe 6253. To withstand high temperatures and ensure that the inner diameter remains unchanged, the core-fixing mold 6257 is made of boron nitride ceramic. The core-fixing mold 6257 made of boron nitride ceramic has very high precision, thereby ensuring the coaxiality of the steel wire 6262 entering the furnace and making the copper layer covering the steel wire 6262 more uniform in thickness.

[0071] like Figure 13 and Figure 14 As shown, the cooling pipe 6253 includes an inlet 6251 and an outlet 6252, as well as a cooling water channel connecting the inlet 6251 and the outlet 6252. The inlet 6251 and the outlet 6252 are located at the second end of the cooling pipe 6253. Cooling water entering from the inlet 6251 flows through a "C"-shaped flow channel in the cooling water channel before reaching the outlet 6252. To facilitate the connection of cooling water, a suitable connector 6258 is also fitted onto the second end of the cooling pipe 6253. The connector 6258 has an inlet and an outlet corresponding to the positions of the inlet 6251 and the outlet 6252, respectively. To prevent gases such as oxygen in the air from interfering with the crystallization process, a nitrogen port 6259 is also provided on the side wall of the second end of the cooling pipe 6253.

[0072] The working process of the copper cladding mechanism: In the specific implementation process, charcoal can be added to any furnace chamber to consume the oxygen in that chamber. Electricity is applied to the first heating device to dissolve the copper rod to be melted. Under the influence of electromagnetic induction, the copper rod slowly melts into molten copper. As time progresses, the molten copper travels from the first furnace chamber 611 through the second furnace chamber 612 to the third furnace chamber 613. Because the second heating device is placed in the third furnace chamber 613, the molten copper maintains a stable liquid phase state until the liquid level gradually surpasses the height of the steel wire 6262. Before entering the copper plating mechanism, the steel wire 6262 is preheated to 1000℃. Simultaneously, the steel wire 6262 moves in a step-by-step, intermittent manner, meaning it moves a certain distance at regular intervals to ensure sufficient contact between the molten copper and the steel wire 6262. After entering the second crystallizer 629, nitrogen gas is blown into the cooling pipe 6253 through the nitrogen port 6259. Molten copper enters the gap between the cooling pipe 6253 and the steel wire 6262 through the injection hole 6256. Cold water flows in through the inlet of connector 6258 and flows out along the cold water channel. The molten copper slowly cools in contact with the steel wire 6262, forming a soft, uniformly thick copper layer on the surface of the copper wire. This layer is then pulled out by a drive unit located outside the copper melting furnace and enters the cooling mechanism 9 for further cooling. It is important to note that operators continuously add copper rods, charcoal, and other necessary raw materials to the copper melting furnace to ensure that the content of molten copper and gases in the furnace always meets production standards.

[0073] Furthermore, such as Figure 1 As shown, the copper-clad steel production line provided in this embodiment also includes a wire feeding mechanism 11, a connecting mechanism 7, a cooling mechanism 9, and a take-up mechanism 12. The wire feeding mechanism 11 is suitable for coiling and storing the workpieces to be processed after rolling by the continuous rolling mill; the connecting mechanism 7 is located at the outlet of the wire feeding mechanism 11 and is suitable for fixing the end of the previous coil of workpieces to the beginning of the next coil; the cooling mechanism 9 is located at the outlet of the copper-clad mechanism 6 and performs a cooling operation on the workpieces after copper cladding, ensuring a uniform copper layer texture; the take-up mechanism 12 is suitable for coiling and storing the finished copper-clad workpieces. For example, in this embodiment, the connecting mechanism 7 uses a movable rail welder to weld the end of the previous coil of workpieces to the beginning of the next coil of workpieces into one piece.

[0074] The copper-clad steel production line provided in this embodiment has a traction mechanism adapted to provide the power required for transporting the workpieces to be processed in various stages of the copper-clad steel production line. The traction mechanism includes a first traction unit 131, a second traction unit 132, a third traction unit 133, a fourth traction unit 134, and a fifth traction unit 135. Specifically, the first traction unit 131 is located at the discharge port of the wire feeding mechanism 11; the second traction unit 132 is located at the discharge port of the vertical straightening member 22 of the straightening mechanism 2; the third traction unit 133 is located at the discharge port of the rotary straightening member 21 of the straightening mechanism 2; the fourth traction unit 134 is located between the condenser and the grinding mechanism 4; and the fifth traction unit 135 is located at the discharge port of the cooling mechanism 9. For example, in this embodiment, each traction unit includes a set of drive components, which provide the power for moving the workpieces, enabling continuity between adjacent processes to achieve continuous composite processing.

[0075] Therefore, the workpiece to be processed sequentially passes through the wire feeding mechanism 11, the connecting mechanism 7, the straightening mechanism 2, the swing amplitude detection mechanism 3, the polishing mechanism 4, the two-dimensional fine-tuning mechanism 5, the heating mechanism 8, the copper plating mechanism 6, the cooling mechanism 9, and the wire take-up mechanism 12. That is, the workpiece to be processed enters the connecting mechanism 7 and the straightening mechanism 2 sequentially after passing through the wire feeding mechanism 11. After passing through the straightening mechanism 2, the workpiece enters the swing amplitude detection mechanism 3 for inspection with precise horizontal and vertical alignment. Specifically, the blank areas created by the friction between the workpiece and the display component allow the operator to judge whether to proceed to the next step. If it can proceed to the next process, the workpiece enters the polishing mechanism 4 for polishing, where four polishing components can evenly polish the outer wall of the workpiece. If it cannot proceed to the next process, the workpiece is replaced and the process is repeated. The workpiece is then inspected; after polishing, it enters the two-dimensional fine-tuning mechanism 5 to adjust its coaxiality to ensure it is coaxial with the furnace used later; the adjusted workpiece is heated in the heating mechanism 8 until it meets the conditions for copper plating, and then enters the copper plating mechanism to perform the copper plating operation; the copper-plated workpiece enters the cooling pipe 6253 for cooling, and nitrogen is blown into the cooling pipe 6253 through the nitrogen port 6259 to dry the surface of the copper layer; finally, the copper-clad steel with the copper layer is wound up by the winding mechanism 12.

[0076] The copper-clad steel production line with the above structure, through the setting of a traction structure, enables the production line to transport the workpiece to be processed under the drive of external force; since the straightening mechanism 2 can rotate relative to the workpiece to be processed, it can straighten any defects in the workpiece during the rotation process; a swing amplitude detection mechanism 3 is set up to detect the swing amplitude of the workpiece to be processed, which can allow the operator to confirm whether to proceed to the next process in a timely manner, thereby controlling the production cost of the workpiece to be processed; a grinding mechanism 4 is set up to grind the surface of the workpiece to be processed until the surface accuracy meets the requirements of copper-clad steel composite. Since the workpiece to be processed has passed through the above-mentioned straightening mechanism 2, swing amplitude detection mechanism 3, grinding mechanism 4 and two-dimensional fine adjustment mechanism 5, the cross-sectional dimensions of the workpiece to be processed along the traction direction can be made more accurate, which is beneficial to improving the coaxiality of the copper-clad steel during copper plating, thereby ensuring the uniformity of the copper layer. A two-dimensional fine-tuning mechanism 5 is also provided to recalibrate the levelness and verticality of the workpiece. In addition, a heating mechanism 8 is provided between the two-dimensional fine-tuning mechanism 5 and the copper plating mechanism 6, and the heating element is electrically connected to an external switch to preheat the workpiece before it enters the copper plating mechanism 6. The copper plating mechanism 6 is also provided to perform copper plating on the preheated workpiece, so that the copper-clad steel production line has the ability to plating copper and the finished copper-clad steel has better performance.

[0077] Example 2 This embodiment provides a copper-clad steel production line, which differs from the copper-clad steel production line provided in Embodiment 1 in that the alarm structure includes a guide rail, a slider, and a second detection element. The guide rail is mounted on the rod body 32, the slider is mounted on the guide rail, and the second detection element is mounted on the guide rail. In the detection state, the slider can slide along the extension direction of the guide rail under the drive of the workpiece to be processed. When the swing amplitude of the workpiece to be processed exceeds the lower end of the coal powder coating, the workpiece to be processed touches the slider mounted on the guide rail. The slider slides along the extension direction of the guide rail under the drive of the workpiece to be processed, thereby detecting the position change of the slider on the guide rail. This allows technicians to easily observe whether the swing amplitude of the workpiece to be processed exceeds the preset range, thereby inferring whether the produced workpiece to be processed has broken.

[0078] Example 3 The copper-clad steel production line provided in this embodiment, such as Figures 4 to 6As shown, compared with the copper-clad steel production line provided in Embodiment 1 or Embodiment 2, the grinding mechanism 4 differs in that: the grinding mechanism includes a frame 47, a first grinding mechanism, and a second grinding mechanism. The first grinding mechanism and the second grinding mechanism adopt the grinding mechanism in the above embodiments. The frame 47 is provided with a channel suitable for the workpiece to be processed to pass through. The two grinding mechanisms are respectively fixedly installed at both ends of the frame 47, and the two second mounting holes 411 are on the same axis as the channel on the frame 47. The first grinding mechanism is provided with a first flap wheel and a second flap wheel, and the second grinding mechanism is provided with a third flap wheel and a fourth flap wheel. The axis connecting the first flap wheel and the second flap wheel is the first connecting line, and the axis connecting the third flap wheel and the fourth flap wheel is the second connecting line. The first connecting line and the second connecting line are spatially perpendicular. The two flap wheels on the same grinding mechanism are respectively located on both sides of the second mounting hole 411.

[0079] By arranging the two sets of flap wheels on the two grinding mechanisms perpendicularly to each other in space, when grinding the workpiece, the first and second flap wheels at one end are staggered with the third and fourth flap wheels at the other end. This allows for uniform grinding of the outer wall of the workpiece in all directions, improving work efficiency, reducing the labor intensity of manual operation, and improving the quality of the workpiece.

[0080] In this embodiment, a first support member 48 is installed at the entry point of the workpiece on the frame 47. The first support member 48 is coaxially arranged with the second mounting hole 411. When the workpiece is being polished, it can support the workpiece and make the workpiece more stable during the polishing process.

[0081] As a further variation, the frame 47 is cylindrical, and two grinding mechanisms 4 are respectively installed at both ends of the frame 47. The frame 47 is equipped with a drive mechanism to drive the frame 47 to rotate in the axial direction. During the grinding process of the workpiece, the flap wheel grinds the workpiece while the frame 47 rotates, which allows the flap wheel to grind various positions on the surface of the workpiece, improving grinding efficiency, reducing the labor intensity of manual operation, and improving the quality of the workpiece.

[0082] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
