Description

Technical Field

[0001] This invention relates to the field of wire and cable manufacturing technology, specifically to a special-shaped enameled conductor manufacturing apparatus, method, and system. Background Technology

[0002] As the transmission capacity of high-voltage cables or submarine cables increases, the required cross-sectional area of ​​the cable conductors also increases. Considering the water-blocking requirements of high-voltage cables or submarine cables, split conductors have poor water-blocking performance, and the cross-section of circular monofilament conductors produced by circular compression is generally no more than 2000 mm². 2 Due to their high compression coefficient, good water resistance, and ability to produce large cross-sectional areas, irregularly shaped conductors are increasingly used. Meanwhile, to improve the economics of high-voltage cables, the cable industry is developing low AC resistance conductor technology. Currently, the main methods involve producing conductors with copper / aluminum alloy monofilaments with oxide films or enameled copper / aluminum alloy monofilaments to reduce the skin effect, thereby lowering the AC resistance and increasing the cable's transmission capacity. Conventional conductor production equipment includes stranding machines and compression dies. However, using conventional equipment can easily lead to irregularly shaped monofilaments twisting during production, resulting in an uneven conductor surface and paint peeling after passing through the compression die, failing to meet production requirements. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a production device, method and production system for irregular enameled conductors, which improves the current conductor production equipment and avoids problems such as single wire edge turning and paint peeling that occur in the production process of irregular enameled conductors.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, embodiments of the present invention disclose a production apparatus for irregularly shaped enameled conductors, including a frame stranding machine and a mold located on one side of the frame stranding machine. The frame stranding machine includes two first support seats and a second support seat. The second support seat is located close to the mold. A hollow rotating shaft passes through the first support seat and the second support seat. The hollow rotating shaft is fixed to a wire spool mechanism. Irregularly shaped wire positioning control mechanisms are fixed to the hollow rotating shaft portions on both sides of the second support seat. The irregularly shaped wire positioning control mechanism includes a fixed disk coaxially fixed to the hollow rotating shaft. Multiple control wheel groups are arranged circumferentially on the fixed disk. The control wheel groups include a first control wheel and a second control wheel arranged opposite to each other. The first control wheel and the second control wheel are rotatably connected to the fixed disk, and a threading space matching the cross-sectional shape of the irregularly shaped enameled conductor wire is formed between the first control wheel and the second control wheel to limit the wire.

[0005] Optionally, the fixed disk is provided with multiple control wheel assembly mounting cavities along the circumference. A first wheel axle is provided in the control wheel assembly mounting cavity, and the first control wheel is rotatably connected to the first wheel axle. A second wheel axle is provided in the control wheel assembly mounting cavity, and the second control wheel is rotatably connected to the second wheel axle.

[0006] Optionally, the plane containing the end faces of the first and second control wheels has a set acute angle with the plane perpendicular to the axis of the fixed disk.

[0007] Optionally, along the direction of the silk thread's movement, a tension control mechanism is provided between the irregular thread position control mechanism and the silk reel mechanism located in front of the second support seat. The tension control mechanism includes a fixed cylinder that is sleeved on the outer circumference of the hollow rotating shaft and fixed to the hollow rotating shaft. Multiple fixed seats are arranged circumferentially on the outer side of the fixed cylinder. The fixed seats are provided with a first guide wheel and a second guide wheel that can move towards or away from each other.

[0008] Optionally, the distribution direction of the first guide wheel and the second guide wheel forms a set acute angle with the plane perpendicular to the axis of the hollow rotating shaft.

[0009] Optionally, a wire gathering disk is provided at the end of the hollow rotating shaft near the mold. The wire gathering disk has multiple openings along the circumference for the wires to pass through. The diameter of the circumference where the center of the multiple openings is located is the first diameter, and the diameter of the circumference where the center of the wire-passing space of the multiple first control wheel groups is located is the second diameter. The first diameter is smaller than the second diameter so as to initially gather the multiple wires before they enter the mold.

[0010] Optionally, the opening is provided with multiple guide rollers, which are rotatably connected to the wire gathering disk, and the spatial shape formed by the multiple guide rollers matches the cross-sectional shape of the wire.

[0011] Optionally, the second support base is provided with multiple threading holes along the circumference for the thread to pass through.

[0012] Secondly, embodiments of the present invention disclose a working method of the special-shaped enameled conductor production device described in the first aspect. When the hollow rotating shaft rotates, multiple wires led out by the wire spool mechanism pass through the wire threading space of the control wheel group of two special-shaped wire position control mechanisms in sequence, and then are twisted with the conductor part that has been twisted in the mold to form a new twisted layer.

[0013] Thirdly, embodiments of the present invention disclose a special-shaped enameled conductor production system, including multiple special-shaped enameled conductor production devices as described in the first aspect, wherein the multiple special-shaped enameled conductor production devices are connected in series along the direction of the movement of the special-shaped enameled conductor wires.

[0014] The beneficial effects of this invention are as follows: In the special-shaped enameled conductor production device of the present invention, the hollow rotating shafts on both sides of the second support seat are fixed with special-shaped wire positioning control mechanisms. A threading space matching the cross-sectional shape of the wire of the special-shaped enameled conductor is formed between the first control wheel and the second control wheel of the special-shaped wire positioning control mechanism. The wire can pass through this threading space and is limited by the threading space. The wire is limited by the threading space at two positions, and the wire will not twist, that is, it will not flip over, ensuring the roundness of the conductor surface and guaranteeing the forming quality of the conductor. The irregular enameled conductor production apparatus of the present invention has a wire gathering disk at the end of the hollow rotating shaft. The wire gathering disk has multiple openings. Through the wire gathering disk, multiple wires can be initially gathered before entering the mold, thereby reducing the angle at which multiple wires enter the mold to meet the requirements. This avoids the phenomenon of the enamel film falling off due to the wires being scratched by the mold when entering the mold due to the excessive angle, thus improving the surface quality of the conductor.

[0017] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0018] Irregularly shaped enameled conductors are conductors made of stranded wires. The wires are wires with cross-sections of trapezoidal, rectangular, or square shapes, and their surfaces are uniformly coated with insulating varnish.

[0019] In this embodiment, the cross-section of the wire is trapezoidal, with a shorter base and a longer top. There is a waist between the ends of the top and bottom sides on the same side. When twisting, the shorter base of the trapezoidal cross-section of the wire is oriented inward.

[0020] Example 1 This embodiment provides a production apparatus for irregularly shaped enameled conductors, such as... Figures 1-2 As shown, the device includes a frame stranding machine and a mold 1 located on one side of the frame stranding machine. The mold 1 is fixed on a base 2. The frame stranding machine includes a hollow rotating shaft 3. The hollow rotating shaft 3 has a channel inside for the stranded conductor portion to pass through. The hollow rotating shaft 3 passes through a first support seat 4 and a second support seat 5 in sequence. The first support seat 4 and the second support seat 5 support the hollow rotating shaft 3. The hollow rotating shaft 3 is rotatably connected to the first support seat 4 and the second support seat 5, so that the hollow rotating shaft 3 can rotate around its own axis.

[0021] In this embodiment, the second support seat 5 is positioned closer to the mold 1, that is, along the direction of the silk thread movement, the first support seat 4 is positioned forward and the second support seat 5 is positioned backward.

[0022] A wire spool mechanism is fixed on the hollow rotating shaft 3. The wire spool mechanism is used to set multiple wire spools and drive the wire spools to rotate.

[0023] The silk reel mechanism can be made using existing technology, including multiple support plates 6. The inner edge of the support plate 6 is fixedly connected to the axial surface of the hollow rotating shaft 3. Multiple silk rollers 7 are vertically arranged on the support plate 6. The silk rollers 7 are rotatably connected to the support plate 6 through the silk roller shaft. The silk rollers 7 are used to wind silk threads. The silk rollers 7 can rotate to release the silk threads.

[0024] The two ends of the support plate 6 are fixedly connected to the rotating drive ring 8. The rotating drive ring 8 cooperates with the roller frame 9, and the roller frame 9 is used to support and drive it to rotate, thereby realizing the rotation of the hollow rotating shaft 3 around its own axis.

[0025] The roller frame 9 can be made using existing equipment, and its specific structure will not be described in detail here.

[0026] In this embodiment, the existing technology can be used for the silk reel mechanism, and its further technical details will not be described in detail here.

[0027] In this embodiment, an improvement is made to the structure of the current frame stranding machine. A special-shaped wire position control mechanism is set on both sides of the second support seat 5 and fixedly connected to the hollow rotating shaft. The one closer to the wire spool mechanism is the first special-shaped wire position control mechanism 10, and the one closer to the mold is the second special-shaped wire position control mechanism 11. The special-shaped wire drawn from the wire roller 7 passes through the first special-shaped wire position control mechanism 10 and the second special-shaped wire position control mechanism 11 in sequence to prevent the wire from twisting and causing the overturning phenomenon.

[0028] The first irregular line position control mechanism 10 and the second irregular line position control mechanism 11 have the same structure. The first irregular line position control mechanism 10 will be used as an example for explanation: like Figures 3-4 As shown, the first irregular line position control mechanism 10 includes a support disk 10-1, a hollow rotating shaft 3 passing through the center of the support disk 10-1, the hollow rotating shaft 3 being coaxially and fixedly connected to the support disk 10-1, and multiple control wheel groups being arranged circumferentially on the support disk 10-1. Preferably, the multiple control wheel groups are arranged at equal intervals along the circumferential direction of the support disk.

[0029] The control wheel assembly includes a first control wheel 10-2 and a second control wheel 10-3 arranged opposite to each other. A threading space 10-4 for the thread to pass through is formed between the first control wheel 10-2 and the second control wheel 10-3. The shape of the threading space 10-4 matches the cross-sectional shape of the thread. In this embodiment, the cross-sectional shape of the thread is trapezoidal. Therefore, the threading space 10-4 is a trapezoidal space that matches the cross-section of the thread. After the thread passes through the threading space 10-4, the thread will not twist or turn under the limiting effect of the threading space 10-4.

[0030] In this embodiment, the first control wheel 10-2 includes a cylindrical part, and two ends of the cylindrical part are provided with frustum parts. The smaller end of the frustum part is fixedly connected to the end of the cylindrical part. A space is formed between the two frustum parts to cooperate with the second control wheel. The second control wheel 10-3 is a cylindrical wheel that extends into the space between the two frustum parts. The wheel surface of the cylindrical wheel, the inner side surface of the two frustum parts, and the outer side surface of the cylindrical part form a wire-passing space with a trapezoidal cross-section.

[0031] Specifically, the support plate 10-1 has multiple control wheel assembly mounting cavities at equal intervals along the circumference. The number of control wheel assembly mounting cavities corresponds to the number of control wheels, and the control wheels are installed in the corresponding control wheel assembly mounting cavities.

[0032] The control wheel assembly mounting cavity is provided with a first wheel axle, and the first control wheel 10-2 is rotatably connected to the first wheel axle. The control wheel assembly mounting cavity is provided with a second wheel axle, and the second control wheel 10-3 is rotatably connected to the second wheel axle.

[0033] In this embodiment, the plane containing the end faces of the first control wheel 10-2 and the second control wheel 10-3 has a set acute angle with the plane perpendicular to the axis of the support disk 10-1, so that the wire can be twisted onto the conductor part that has been twisted under the rotation of the hollow rotating shaft 3.

[0034] The second irregular line position control mechanism 11 has the same structure as the first irregular line position control mechanism 10, and will not be described again here.

[0035] In this embodiment, the wire is limited by the threading space at two positions, so the wire will not twist or flip over, ensuring the conductor surface is round and guaranteeing the conductor forming quality.

[0036] The hollow rotating shaft 3 between the first irregular wire position control mechanism 10 and the wire disc mechanism is also fixed with a tension control mechanism 12.

[0037] In this embodiment, as Figures 5-6 As shown, the tension control mechanism 12 includes a fixed cylinder 12-1 that is sleeved on the outer periphery of the hollow rotating shaft 3 and fixed to the hollow rotating shaft 3. Multiple fixed seats 12-2 are arranged circumferentially on the outer side of the fixed cylinder 12-1. The fixed seats 12-2 are provided with a first guide wheel 12-3 and a second guide wheel 12-4 that can move towards or away from each other.

[0038] The first guide wheel 12-3 is rotatably connected to the first wheel seat, the second guide wheel 12-4 is rotatably connected to the second wheel seat, and the first wheel seat and the second wheel seat are connected to the fixed seat.

[0039] In one embodiment, one of the first wheel seat and the second wheel seat is fixedly connected to the fixed seat 12-2, and the other is slidably connected to the fixed seat 12-2 via a guide rail.

[0040] For example, the first wheel seat is fixedly connected to the fixed seat 12-2, and the second wheel seat is slidably connected to the fixed seat 12-2 via a guide rail. A locking component is provided between the second wheel seat and the guide rail to achieve locking and fixing with the fixed seat 12-2. Preferably, the locking component is a locking bolt that is threadedly connected to the second wheel seat. The locking bolt can abut against the guide rail to achieve locking and fixing of the second wheel seat and the guide rail.

[0041] In another embodiment, both the first wheel seat and the second wheel seat are slidably connected to the fixed seat 12-2 via the guide rail. Both the first wheel seat and the second wheel seat are provided with locking components between themselves and the guide rail. The locking components are locking bolts. Both the first wheel seat and the second wheel seat are threadedly connected with locking bolts. The locking bolts can abut against the guide rail to lock and fix the first wheel seat and the second wheel seat.

[0042] In this embodiment, the first guide wheel 12-3 is positioned closer to the wire disc mechanism, and the second guide wheel 12-4 is positioned closer to the first irregular wire positioning control mechanism.

[0043] When threading the wire, it first passes around the first guide wheel 12-3 from the outside, and then passes around the second guide wheel 12-4 from the inside. Adjusting the distance between the first guide wheel 12-3 and the second guide wheel 12-4 can apply tension to the wire. In this embodiment, since the wire has a large cross-sectional area and high rigidity, the smaller the distance between the first guide wheel 12-3 and the second guide wheel 12-4, the greater the change in the wire's extension path and the greater its resistance. Conversely, the greater the distance, the smaller the resistance. Therefore, adjusting the distance between the first guide wheel 12-3 and the second guide wheel 12-4 plays a role in tension adjustment, ensuring that the wire has sufficient tension and preventing the wire from twisting and turning before entering the mold.

[0044] The distribution direction of the first guide wheel 12-3 and the second guide wheel 12-4, i.e. the extension direction of the line connecting the centers of the first guide wheel 12-3 and the second guide wheel 12-4, has a set acute angle with the plane perpendicular to the axis of the hollow rotating shaft 3. In this embodiment, since the cross-sectional area of ​​the single filament of the wire is large and the cavity is rigid, a pre-torque can be applied to the wire drawn out by the wire reel mechanism through the first guide wheel 12-3 and the second guide wheel 12-4, which changes the extension angle of the wire, which is beneficial to the twisting of the wire in the later stage and reduces the difficulty of operation.

[0045] The first guide wheel 12-3 and the second guide wheel 12-4 cooperate with the silk thread through the wheel surface, so that they will not generate scratching force on the surface of the silk thread, thus avoiding the paint film from being scratched off.

[0046] In this embodiment, if the wire directly enters the mold due to the second irregular wire positioning control mechanism, and the angle between the wire and the mold axis is too large, the mold will scrape the wire, causing the paint film on the wire to fall off.

[0047] Therefore, as Figures 7-8 As shown, in this embodiment, a wire gathering disk 13 is provided at the end of the hollow rotating shaft near the mold. The wire gathering disk 13 is coaxially arranged with the hollow rotating shaft 3. Multiple openings 13-1 for the wire to pass through are provided on the wire gathering disk 13 along its circumference. The axis of the opening forms a set acute angle with the plane perpendicular to the axis of the wire gathering disk.

[0048] In this embodiment, the diameter of the circumference of the center of the multiple openings 13-1 on the wire gathering disk is the first diameter, and the diameter of the circumference of the center of the multiple threading spaces of the second irregular wire position control mechanism 11 is the second diameter. The first diameter is smaller than the second diameter, so that multiple wires can be gathered by the wire gathering disk 13. After the wires pass through the wire gathering disk, they enter the mold 1. Since the wire gathering disk 13 gathers the wires, the angle between the wires and the axis of the mold 1 is reduced, and the problem of paint film falling off caused by the mold 1 rubbing against the wires is avoided.

[0049] Furthermore, since the cross-section of the thread is trapezoidal and the cross-section of the opening is circular, in order to avoid the thread from colliding with the side of the opening when passing through it, causing deformation or damage to the thread, multiple guide rollers 13-2 are provided inside the opening. The guide rollers 13-2 are rotatably connected to the wire collecting disk 13 and can rotate around their own axis. The space enclosed by the multiple guide rollers 13-2 matches the cross-section of the thread.

[0050] In this embodiment, since the cross-section of the thread is trapezoidal, four guide rollers 13-2 are provided. The four guide rollers 13-2 form a trapezoidal space for the thread to pass through. The thread contacts the guide rollers 13-2. Since the guide rollers 13-2 can rotate, damage caused by rigid collision between the thread and the inner side of the opening is avoided.

[0051] Furthermore, such as Figure 9 As shown, the second support seat 5 has multiple wire holes 5-1 evenly spaced along the circumference. The position of the wire holes 5-1 matches the wire threading space of the first irregular wire position control mechanism 10 and the second irregular wire position control mechanism 11. The axis of the wire holes 5-1 forms a set acute angle with the plane perpendicular to the axis of the hollow rotating shaft 3.

[0052] By setting the threading hole 5-1, the thread can pass through the second support 5. At the same time, a porcelain sleeve is provided inside the threading hole 5-1. The two sides of the porcelain sleeve adopt an arc structure to increase the smoothness of the thread passing through the threading hole 5-1 and avoid the thread from being scratched.

[0053] In this embodiment, compared with conventional irregular enameled conductor production equipment, only the first irregular wire position control mechanism 10, the second irregular wire position control mechanism 11, the tension control mechanism 12, the wire gathering plate 13, and the wire threading hole 5-1 are added. The remaining structures can adopt the existing technology of current conductor production equipment, and will not be described in further detail here.

[0054] Example 2 This embodiment provides a working method of the special-shaped enameled conductor production device described in Embodiment 1. After the wire is drawn out from the wire roller, it passes around the first guide wheel 12-2 from the inside and the second guide wheel 12-3 from the outside. Then, it passes through the wire threading space through the first special-shaped wire positioning control mechanism 10, through the wire threading hole 5-1 through the second support seat 5, through the wire threading space through the second special-shaped wire positioning control mechanism 11, and through the opening 13-1 through the wire collecting reel 13 before entering the mold 1 to cooperate with the conductor part that has been twisted. Under the drive of the roller frame 9, the hollow rotating shaft 3 rotates, thereby twisting multiple wires on the conductor part that has been twisted using the mold 1 to form a new twisted layer. The conductor part that has been twisted enters the mold after passing through the hollow rotating shaft.

[0055] The method of multiple wires entering mold 1 and twisting them on the surface of the already twisted conductor portion using mold 1 can be achieved using existing technology and will not be described in detail here.

[0056] The subsequent processing steps for the stranded conductors can be carried out using existing technologies, and will not be described in detail here.

[0057] During the stranding process, the threading space acts as a limit for the strands. The strands are limited at two positions by the threading space, preventing them from twisting or turning over. This ensures the conductor surface is round and guarantees the conductor forming quality.

[0058] Example 3 This embodiment provides a special-shaped enameled conductor production system, which includes multiple special-shaped enameled conductor production devices as described in Embodiment 1. The multiple special-shaped enameled conductor production devices are connected in series along the direction of the wire movement, and each special-shaped enameled conductor production device corresponds to the stranding of a layer of stranded wire.

[0059] The remaining structure of the irregular enameled conductor production system can be achieved using existing technology, and will not be described in further detail here.

[0060] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
