Abstract
Description
Technical Field
[0001] This application relates to the field of cable manufacturing, and in particular to a stranding device for producing mining cables. Background Technology
[0002] In cable production, the stranding process is one of the core processes. Its main function is to strand multiple single conductors into a cable core that meets specifications according to a preset stranding pitch and direction. The stranding quality directly determines the electrical performance, mechanical strength, and service life of the cable. The lead reel of the cable stranding machine, as the conductor feeding component, has a conductor guiding accuracy between its discharge port and the stranding die, which is one of the key factors affecting the stranding quality.
[0003] In related technologies, existing cable stranding machines typically use structures such as fixed wire guide holes, simple guide wheels, or rigid guide sleeves to guide the conductors at the lead-in reel outlet. The core design idea is to restrict the conductor's trajectory through a fixed structure, guiding the conductor smoothly from the lead-in reel into the stranding die for stranding. Among these, the fixed wire guide hole structure is the simplest, using only a through-hole on the lead-in reel to limit the conductor's movement; the simple guide wheel structure uses a rotatable guide wheel to change the conductor's direction, reducing friction between the conductor and the guiding structure; and the rigid guide sleeve uses a fixed-shaped sleeve to position and guide the conductor. All three are widely used conventional guiding methods in the industry.
[0004] Regarding the aforementioned technologies, in actual production, due to the requirements of the cable stranding process, the conductors need to be tilted to change their trajectory after exiting the lead reel in order to smoothly enter the paralleling die. The existing guiding structures all have the following technical defects, specifically manifested as follows: Existing fixed wire guide holes, simple guide wheels, or rigid guide sleeves are all fixed structures, unable to adaptively adjust the guide angle and bending radius according to the actual direction and tension of the conductor. Furthermore, during the stranding process of cables of different specifications, the conductor diameter, stranding speed, and entry angle all change. The guide angle and bending radius of existing guide structures are fixed and cannot be adjusted in real time according to these changes in working conditions. This necessitates manual adjustment of the guide structure's position or replacement with guide components of different specifications, which not only increases the labor intensity of operators and reduces production efficiency but also easily leads to decreased guide accuracy due to manual adjustment deviations, further affecting the stranding quality. Summary of the Invention
[0005] In order to enable the adjustment of the guide angle and bending radius of the output conductor of the lead coil, this application provides a stranding device for the production of mining cables.
[0006] The technical solution of the stranding device for producing mining cables provided in this application is as follows: A stranding device for producing mining cables includes a support, a wire feeding turntable, a wire paralleling die, and multiple wire feeding wheels. The wire feeding turntable is rotatably connected to the support, the wire paralleling die is located on the discharge side of the wire feeding turntable, and the multiple wire feeding wheels are evenly spaced along the circumference of the wire feeding turntable. The device is characterized by further comprising: The lead wire reel is coaxially connected to the wire feeding turntable. The lead wire reel is equipped with multiple adaptive wire guiding mechanisms that correspond one-to-one with the multiple wire feeding wheels. The lead wire reel outputs wires to the paralleling die through the adaptive wire guiding mechanisms. The adaptive wire guiding mechanisms can adjust the guide angle and bending radius of the wires.
[0007] Optionally, the lead plate is provided with through holes corresponding to the plurality of adaptive conductor mechanisms, and the adaptive conductor mechanism is disposed in the corresponding through hole; the adaptive conductor mechanism includes; The elastic plate has one end rotatably disposed at the discharge port of the through hole, and the other end bends outward from the discharge port. The elastic plate is provided with multiple limiting rings, which are distributed at intervals along the length of the elastic plate.
[0008] Optionally, the adaptive conductor mechanism further includes; A wire guide ring is coaxially installed inside the wire guide hole; the discharge end of the wire guide ring is provided with a coaxial annular liquid storage tank; Magnetorheological fluid is filled in the annular reservoir. An annular cap, rotatably connected to the wire guide ring, is used to seal the opening of the annular liquid storage tank; An electromagnet, mounted on the wire loop, is used to apply a magnetic field to the magnetorheological fluid; A positioning rod, one end of which is hinged to the elastic plate, the middle part of which is slidably and rotatably connected to the annular cover, and the other end of which is connected to a limiting plate located in the annular liquid storage tank.
[0009] Optionally, the annular cover is provided with a radially arranged groove and a slider slidably connected to the groove; The positioning rod has a slidably connected rotating ball in the middle, and the rotating ball is rotatably connected to the slider; The adaptive guide mechanism also includes; An elastic telescopic cover is connected at one end to the positioning rod and at the other end to cover the slide groove, so that the magnetorheological fluid cannot leak from the slide groove.
[0010] Optionally, the magnetorheological fluid is a lubricating magnetorheological fluid that can lubricate the annular cover, the rotating ball, the slider, and the positioning rod.
[0011] Optionally, there are multiple limiting plates, all of which intersect with the positioning rod.
[0012] Optionally, the end of the positioning rod away from the elastic plate is provided with a coaxial spring rod.
[0013] Optionally, the end of the spring rod away from the positioning rod is provided with a ball bearing.
[0014] Optionally, the positioning rod is not perpendicular to the annular cover.
[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. In this application, under the tension of the conductor, the components work together: the annular cover rotates and adjusts synchronously with the conductor trajectory, and the elastic plate bends flexibly with the conductor trajectory, so that the conductor always maintains a smooth transition with a large radius, and the conductor is not easily damaged by sharp bends with a small radius. Moreover, it can adapt to the bending angle requirements of conductors with different specifications and working conditions without manual adjustment.
[0016] 2. In this application, the electromagnet installed on the guide ring is intermittently activated, intermittently applying a magnetic field to the magnetorheological fluid, causing the fluid to intermittently and instantaneously change from a liquid to a solid state. Multiple limiting plates intersecting with the positioning rod increase the contact area between the positioning rod and the magnetorheological fluid, enabling the fluid to produce a uniform and stable instantaneous damping positioning effect on the positioning rod. This effectively suppresses the shaking of the positioning rod and the oscillation of the elastic plate, thereby suppressing wire swaying and wire skipping, and stabilizing the wire tension. When the magnetorheological fluid is intermittently in a liquid state, it can also intermittently release the limiting effect on the positioning rod and the elastic plate, allowing the elastic plate to adaptively adjust its bending arc according to the wire tension, thus enabling the adaptive wire mechanism to adaptively adjust the guide angle of the wire. Simultaneously, the lubricating magnetorheological fluid continuously lubricates all moving pairs, including the rotating joints of the annular cover and the guide ring, the rotating joints of the rotating ball and the slider, and the sliding joints of the positioning rod and the rotating ball, reducing component friction and wear.
[0017] 3. In this application, the positioning rod end is provided with a spring rod and a ball bearing, which can absorb tension fluctuations and reduce motion resistance; the elastic telescopic cover seals the slide groove to prevent magnetorheological fluid leakage; the positioning rod and the annular cover are arranged in a non-perpendicular manner to avoid motion interference; multiple limiting plates increase the damping area, making the positioning more stable, giving the adaptive conductor mechanism good impact resistance and making it less prone to jamming.
[0018] 4. In this application, each wire feeding reel corresponds to an independent adaptive conductor mechanism, which can guide, adjust the posture and stabilize the tension of a single conductor individually, ensuring that multiple conductors have consistent posture and balanced tension before entering the winding die, effectively improving the uniformity of stranding pitch and the roundness of the cable.

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0023] Reference Figure 1 , Figure 2 and Figure 3This application discloses a stranding device for producing mining cables. The device includes a support 1, a wire feeding turntable 2, a paralleling die 5, and multiple wire feeding wheels 21. The wire feeding turntable 2 is rotatably connected to the support 1. The paralleling die 5 is located on the discharge side of the wire feeding turntable 2. The multiple wire feeding wheels 21 are evenly spaced along the circumference of the wire feeding turntable 2. Specifically, the support 1, wire feeding turntable 2, paralleling die 5, and multiple wire feeding wheels 21 are all existing technologies. Based on production requirements, any existing technology that meets the specified specifications can be selected from the available technologies. The specific models and connection methods of the aforementioned existing technical components, such as the support 1, the wire feeding turntable 2, the paralleling die 5, and the multiple wire feeding wheels 21, can be flexibly selected according to the actual requirements of the cable diameter and stranding speed in the stranding production. Their core function is to realize the wire feeding and initial guidance, providing a foundation for subsequent adaptive guidance and stranding operations. This application does not improve their structure, but only makes reasonable selection and assembly of existing components.
[0024] Reference Figure 1 , Figure 2 and Figure 3 It also includes a lead reel 3, coaxially connected to the pay-off turntable 2. The lead reel 3 is equipped with multiple adaptive conductor mechanisms 4, each corresponding to one of the multiple pay-off rollers 21. The lead reel 3 outputs conductors to the stranding die 5 through the adaptive conductor mechanisms 4. The adaptive conductor mechanisms 4 can adjust the guide angle and bending radius of the conductors. Specifically, the lead reel 3 and the pay-off turntable 2 are coaxially connected through a connecting shaft 22 to ensure that the lead reel 3 and the pay-off turntable 2 rotate synchronously. The adaptive conductor mechanisms 4 are set one-to-one with the pay-off rollers 21, which can realize the independent guidance of a single conductor, ensuring the consistency of the posture of multiple conductors before entering the stranding die 5, and providing a guarantee for the subsequent stranding quality. The adaptive conductor mechanism 4 can adjust the guide angle and bending radius, which can solve the defect of traditional stranding devices that cannot adjust the guide angle and bending radius of the conductors according to the conductor specifications and operating conditions.
[0025] Reference Figure 1 , Figure 2 and Figure 3 The lead plate 3 is provided with through holes 301 corresponding to multiple adaptive lead mechanisms 4, and the adaptive lead mechanism 4 is disposed in the corresponding through hole 301; the adaptive lead mechanism 4 includes: The elastic plate 42 has one end rotatably located at the discharge port of the through hole 301, and the other end bends outward from the discharge port. The elastic plate 42 is provided with multiple limiting rings 421, which are distributed at intervals along the length of the elastic plate 42.
[0026] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the through-hole 301 is used to position and install the adaptive conductor mechanism 4, ensuring that the installation position of each adaptive conductor mechanism 4 corresponds to the corresponding feed roller 21 and the inlet of the parallel die 5, so that the conductor is less likely to deviate during transmission. One end of the elastic plate 42 is rotatably connected to the outlet of the through-hole 301, and can swing flexibly around the rotation point. The design of the other end bending outward can provide a smooth guide trajectory for the conductor in advance. With the help of multiple limiting rings 421 distributed at intervals along the length of the elastic plate 42, the conductor can be limited at multiple points, so that the conductor is less likely to deviate or shake during the guiding process. At the same time, the elastic plate 42 follows the conductor trajectory and bends elastically. Without manual adjustment, the elastic plate 42 can adapt to the bending angle requirements of conductors of different specifications and working conditions when entering the die. Moreover, the conductor always maintains a smooth transition with a large radius through the elastic plate 42, so that the conductor is less likely to be damaged by sharp bends with small radii.
[0027] Reference Figure 1 , Figure 2 and Figure 3 The adaptive conductor mechanism 4 also includes; The wire guide ring 41 is coaxially installed in the wire guide hole 301 to provide initial guidance for the wire; The discharge end of the wire ring 41 is provided with a coaxial annular liquid storage tank 4101, which provides storage space for the subsequent installation of magnetorheological fluid 411. Magnetorheological fluid 411 is filled in an annular storage tank 4101; as the core functional medium, the state of magnetorheological fluid 411 can change rapidly under the magnetic field of electromagnet 412. The annular cover 43 is rotatably connected to the wire guide ring 41 and is used to seal the opening of the annular liquid storage tank 4101. The annular cover 43 and the wire guide ring 41 are rotatably connected, which can not only seal the annular liquid storage tank 4101 to prevent the magnetorheological fluid 411 from leaking, but also rotate synchronously with the guide trajectory of the wire to adapt to the angle adjustment of the wire. An electromagnet 412 is mounted on a wire ring 41 and is used to apply a magnetic field to the magnetorheological fluid 411. A positioning rod 44 is provided, with one end hinged to an elastic plate 42, the middle part of which is slidably and rotatably connected to an annular cover 43, and the other end connected to a limiting plate 441 located within an annular liquid storage tank 4101. The positioning rod 44 can transmit the bending and swinging motion of the elastic plate 42 to the annular liquid storage tank 4101, and, in conjunction with the limiting plate 441, control the attitude of the elastic plate 42. The limiting plate 441 can increase the contact area between the positioning rod 44 and the magnetorheological fluid 411, thereby enhancing the damping effect of the magnetorheological fluid 411 on the positioning rod 44.
[0028] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, when the adaptive conductor mechanism 4 is running, the conductor released by the wire feeding wheel 21 passes sequentially through the inner hole of the wire guide ring 41 and multiple limiting rings 421 before entering the wire-jointing mold 5. Simultaneously, the electromagnet 412 is intermittently activated, causing the magnetorheological fluid 411 to intermittently harden in a magnetic field. The wire guide ring 41 can rotate coaxially, the annular cover 43 can be adjusted circumferentially with the conductor trajectory, and the elastic arc plate can bend elastically. These three components work together to achieve real-time adaptive adjustment of the discharge angle, bending radius, and wire feeding posture. This allows for adaptation to different wire diameters, different stranding speeds, and different mold entry angles without manual adjustment, demonstrating strong versatility. During operation, the intermittent excitation of the electromagnet 412 causes the magnetorheological fluid 411 to intermittently harden, thereby achieving intermittent damped positioning of the positioning rod 44 and the elastic plate 42. This ensures smooth conductor feeding while suppressing tension fluctuations, conductor swaying, and wire skipping, thus stabilizing the wire feeding tension.
[0029] Reference Figure 1 , Figure 2 and Figure 3 The annular cover 43 is provided with a radially arranged sliding groove 4301 and a slider 431 slidably connected to the sliding groove 4301; The positioning rod 44 has a slidably connected rotating ball 45 in the middle, and the rotating ball 45 is rotatably connected to the slider 431. Specifically, the rotating ball 45 has a coaxial sliding hole 4501, and the positioning rod 44 is slidably disposed coaxially in the sliding hole 4501; The adaptive guide mechanism 4 also includes; The elastic telescopic cover 46 is connected to the positioning rod 44 at one end and covers the slide groove 4301 at the other end. The elastic telescopic cover 46 prevents the magnetorheological fluid 411 from leaking from the slide groove 4301.
[0030] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the groove 4301 on the annular cover 43 is arranged radially, and the slider 431 can slide flexibly along the groove 4301. It is rotatably connected to the slider 431 with the rotating ball 45 in the middle of the positioning rod 44, which enables the positioning rod 44 to swing at multiple angles during the sliding process, ensuring that the positioning rod 44 can adapt to the bending trajectory of the elastic plate 42 and is not prone to jamming. The elastic telescopic cover 46 is set to seal the gap between the groove 4301 and the positioning rod 44, preventing the magnetorheological fluid 411 in the annular liquid storage tank 4101 from leaking from the groove 4301. At the same time, the elastic telescopic cover 46 can extend and retract synchronously with the sliding and swinging of the positioning rod 44, without affecting the normal movement of the mechanism, and ensuring the stable operation of the adaptive conductor mechanism 4.
[0031] Reference Figure 1 , Figure 2 and Figure 3 The magnetorheological fluid 411 is a lubricating type magnetorheological fluid 411, which can lubricate the annular cover 43, the rotating ball 45, the slider 431, and the positioning rod 44. In this embodiment, the lubricating type magnetorheological fluid 411 has both magnetorheological and lubricating functions. Compared with ordinary magnetorheological fluid 411, it can not only achieve state switching under the action of a magnetic field and provide damping positioning for the positioning rod 44, but also lubricate all moving pairs such as the rotating joint between the annular cover 43 and the guide ring 41, the rotating joint between the rotating ball 45 and the slider 431, and the sliding joint between the positioning rod 44 and the rotating ball 45, thereby reducing friction and wear between components and extending the service life of the mechanism.
[0032] Reference Figure 1 , Figure 2 and Figure 3 Multiple limiting plates 441 are provided, and all of them intersect with the positioning rod 44. In this embodiment, the multiple limiting plates 441 intersecting with the positioning rod 44 can further increase the contact area between the positioning rod 44 and the magnetorheological fluid 411, making the damping effect of the magnetorheological fluid 411 on the positioning rod 44 more uniform and stable. When the electromagnet 412 is activated and the magnetorheological fluid 411 hardens, the multiple limiting plates 441 can work together to improve the positioning effect on the positioning rod 44, effectively suppress the shaking of the positioning rod 44, and thus ensure the stability of the posture of the elastic plate 42, making it less likely for the wire to swing or skip wires.
[0033] Reference Figure 1 , Figure 2 and Figure 3 The end of the positioning rod 44 furthest from the elastic plate 42 is provided with a coaxial spring rod 442. In this embodiment, the spring rod 442 is coaxially arranged with the positioning rod 44, which can provide a certain elastic buffer when the positioning rod 44 comes into contact with the annular liquid tank 4101 or the magnetorheological fluid 411. When the tension of the wire fluctuates slightly, the spring rod 442 can absorb the tension impact through its own extension and contraction, making it difficult for the tension fluctuation to be transmitted to the elastic plate 42 and the wire, so that the wire is less likely to be thinned or broken due to sudden tension changes. At the same time, the spring rod 442 can also assist the positioning rod 44 in resetting in the magnetorheological fluid 411, improving the response speed of the mechanism.
[0034] Reference Figure 1 , Figure 2 and Figure 3A ball bearing 443 is provided at the end of the spring rod 442 away from the positioning rod 44. In this embodiment, the ball bearing 443 can convert the sliding friction between the spring rod 442 and the inner wall of the annular liquid storage tank 4101 into rolling friction, which greatly reduces the frictional resistance of the spring rod 442 during movement. This makes it less likely for the spring rod 442 to get stuck or wear when it slides relative to the inner wall of the annular liquid storage tank 4101, ensuring that the positioning rod 44 and the spring rod 442 can move flexibly, and further improving the smoothness of the movement of the adaptive guide mechanism 4.
[0035] Reference Figure 1 , Figure 2 and Figure 3 The positioning rod 44 is not perpendicular to the annular cover 43. In this embodiment, the design that the positioning rod 44 is not perpendicular to the annular cover 43 makes the force direction of the positioning rod 44 more reasonable. When the elastic plate 42 bends and drives the positioning rod 44 to move, the positioning rod 44 can smoothly slide and swing within the slide groove 4301, avoiding motion interference caused by the perpendicular setting of the positioning rod 44 and the annular cover 43. This ensures that the adaptive guide mechanism 4 can flexibly adjust the guide angle and bending radius of the guide wire to adapt to different production conditions.
[0036] The implementation principle of a stranding device for producing mining cables according to an embodiment of this application is as follows: The wire feeding reel 21 begins to feed the wire. After being initially guided by the wire feeding turntable 2, the wire enters the wire passing ring 41 in the corresponding wire passing hole 301 on the wire feeding disc 3. The wire passing ring 41 provides initial guidance for the wire to ensure accurate wire direction. Subsequently, the wire passes through multiple limiting rings 421 that are spaced apart along the length of the elastic plate 42. The multiple limiting rings 421 provide multi-point limiting for the wire, making it less likely for the wire to deviate or shake significantly during transmission.
[0037] When the conductor enters the parallel die 5, it needs to tilt and change direction according to the stranding requirements. Under the tension of the conductor, the components work together: the annular cover 43 rotates and adjusts synchronously with the conductor trajectory, and the elastic plate 42 bends flexibly around the conductor trajectory, so that the conductor always maintains a large radius smooth transition and the conductor is not easily damaged by small radius sharp bends. Moreover, it can adapt to the bending angle requirements of conductors entering the die for different specifications and working conditions without manual adjustment.
[0038] Meanwhile, the bending and swinging motion of the elastic plate 42 is transmitted through the hinged positioning rod 44. The rotating ball 45 in the middle of the positioning rod 44 is rotatably connected to the slider 431 in the groove 4301 of the annular cover 43, causing the slider 431 to slide flexibly along the radial groove 4301, realizing the multi-angle swinging of the positioning rod 44. This ensures that the movement trajectory of the positioning rod 44 and the elastic plate 42 are matched. The elastic telescopic cover 46 extends and retracts synchronously with the sliding and swinging of the positioning rod 44, effectively sealing the gap of the groove 4301 and preventing the leakage of the magnetorheological fluid 411. The end of the positioning rod 44 away from the elastic plate 42 drives the limiting plate 441, the spring rod 442 and the ball 443 to float in the magnetorheological fluid 411 in the annular storage tank 4101. The spring rod 442 plays an elastic buffering role, which can absorb the slight fluctuation of the wire tension. The ball 443 converts the sliding friction between the spring rod 442 and the inner wall of the annular storage tank 4101 into rolling friction, reducing the resistance to movement and ensuring the flexible movement of the positioning rod 44 and the spring rod 442.
[0039] During production, the electromagnet 412 installed on the wire guide ring 41 is intermittently activated, intermittently applying a magnetic field to the magnetorheological fluid 411, causing the magnetorheological fluid 411 to intermittently and instantaneously change from a liquid state to a solid state. Multiple limiting plates 441 intersecting with the positioning rod 44 increase the contact area between the positioning rod 44 and the magnetorheological fluid 411, so that the magnetorheological fluid 411 produces a uniform and stable instantaneous damping positioning effect on the positioning rod 44, effectively suppressing the shaking of the positioning rod 44 and the swing of the elastic plate 42, thereby suppressing the wire swing and wire skipping phenomenon, and stabilizing the wire tension. When the magnetorheological fluid 411 is intermittently in a liquid state, it can intermittently release the limiting of the positioning rod 44 and the elastic plate 42, so that the elastic plate 42 can adaptively adjust the bending arc according to the wire tension, thereby enabling the adaptive wire mechanism 4 to adaptively adjust the guide angle of the wire. Meanwhile, the lubricating magnetorheological fluid 411 provides continuous lubrication for all moving pairs, including the rotating pair between the annular cover 43 and the wire ring 41, the rotating pair between the rotating ball 45 and the slider 431, and the sliding pair between the positioning rod 44 and the rotating ball 45, thereby reducing friction and wear of the components. Here, all rotating pairs can be any rotating pairs that meet the production requirements in the existing technology.
[0040] Finally, after the adaptive conductor mechanism 4 adaptively adjusts the guide angle and bending radius of the conductor and stabilizes the tension, multiple conductors simultaneously enter the parallel die 5 to complete the stranding operation. This achieves large-radius, flexible, adaptive-angle, and stable-tension discharge of the conductor, reducing the damage of sharp bends to the conductor, ensuring the stranding quality of mining cables, and the entire process requires no manual intervention. It can adapt to the production needs of different wire diameters, different stranding speeds, and different die entry angles, and has strong versatility.
