Description

Technical Field

[0001] This invention relates to the field of aluminum stranded cable production technology, and in particular to an automatic stranding device for aluminum stranded cables. Background Technology

[0002] In the production of aluminum stranded cables, tubular stranding machines are commonly used to concentrically strand multiple aluminum monofilaments. Before entering the final forming die for stranding, all monofilaments must maintain a precise and consistent radial position and tension. Any momentary imbalance in tension or displacement of any monofilament will lead to structural defects such as "back strands" or "loose strands" in the stranded cable, severely affecting its electrical performance, mechanical strength, and service life.

[0003] Current technologies primarily rely on a tensioning mechanism with consistent pretension at the pay-off reel. However, for complex stranded structures composed of monofilaments of different diameters (e.g., thinner filaments on the inner coil and thicker filaments on the outer coil), a tensioning mechanism with consistent pretension cannot guarantee balanced force on each monofilament. Furthermore, existing equipment lacks automatic and rapid coordinated tensioning capabilities, making machine adjustments difficult. Secondly, during production, instantaneous tension fluctuations caused by factors such as momentary reel jamming, micro-defects on the monofilament surface, or air disturbances cannot be monitored and compensated for in real time. Finally, the guide ring of the wire separator, a critical guiding component, experiences localized groove wear on its inner wall due to friction from the monofilaments in a fixed position over a long period, compromising guiding stability. Traditional solutions require downtime for replacement, leading to frequent unplanned downtime and severely restricting equipment utilization and production continuity.

[0004] Therefore, in order to improve process adaptability, ensure product quality, and guarantee production continuity, this invention provides an automatic stranding device for aluminum stranded cables. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing an automatic stranding device for aluminum stranded cables.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic stranding device for aluminum stranded cables, comprising a frame, a stranding cage mounted on the frame, a forming die located at the right end of the stranding cage, and a tension control system. The right outlet side of the stranding cage is provided with a wire separating plate via a support column, and the wire separating plate is provided with guide rings for each single wire to pass through. The device also includes an online control system for stranding status.

[0007] The online control system for stranded wire status includes a deflection adjustment module and a fluctuation detection module located on the left and right side walls of the splitter plate, as well as an auxiliary tensioning module located on the left side of the splitter plate.

[0008] The fluctuation detection module is used to detect the radial contact state of each monofilament at the corresponding guide ring in real time and generate a detection signal; the auxiliary tensioning module is connected to the fluctuation detection module and is used to apply auxiliary tension to the stranded wire according to the detection signal.

[0009] During the initialization phase, when dealing with the process of twisting together monofilaments of different diameters, such as the inner ring fine filaments and the outer ring coarse filaments, the pressure data fed back by the fluctuation detection module is used to assist the tensioning module in performing batch and coordinated compensation tensioning of the outer ring coarse filaments based on the initial pressure difference caused by the different diameters of the inner and outer ring monofilaments. During the twisting phase, when the pressure abnormality is caused by the wear of the guide ring, the deflection adjustment module drives the guide ring deflection adjustment to switch the unworn arc segment to the working position.

[0010] In the aforementioned automatic stranding device for aluminum stranded cables, the fluctuation detection module includes multiple spring rods fixedly installed on the right side of the splitter plate via a support ring, and a detection arc plate installed on the movable end of the spring rods. A pressure sensor is provided on the side of the detection arc plate away from the spring rods.

[0011] In the above-mentioned automatic stranding device for aluminum stranded cables, the surface of the detection arc plate is perpendicular to the direction of single wire travel, and the detection end of each pressure sensor corresponds one-to-one with the radial inner position of each guide ring.

[0012] In the above-mentioned automatic stranding device for aluminum stranded cables, the auxiliary tensioning module includes a drive unit and a tensioning unit. The tensioning unit includes a support plate fixed on a support column and a disassembly plate installed on the support plate.

[0013] In the above-mentioned automatic stranding device for aluminum stranded cables, multiple tensioning sliders are radially slidable on both the support plate and the disassembly plate. The tensioning sliders are equipped with hooks for hooking the corresponding single wires in the direction away from the center of the support plate. The hooks on the support plate and the disassembly plate correspond to the guide rings set on the inner and outer rings of the wire separating plate, respectively.

[0014] In the above-mentioned automatic stranding device for aluminum stranded cables, the drive unit includes two drive discs that can move independently along the axial direction, and the two drive discs correspond to the support disc and the disassembly disc, respectively.

[0015] In the above-mentioned automatic stranding device for aluminum stranded cables, each drive disc has multiple connecting rods circumferentially distributed on the side facing the tensioning unit. The ends of the connecting rods are provided with wedge-shaped heads, and the sidewall of the tensioning slider is connected with a driven wedge block that cooperates with the inclined surface of the wedge-shaped head.

[0016] In the above-mentioned automatic stranding device for aluminum stranded cables, the deflection adjustment module includes a drive unit and a rotary mounting base. The guide ring is detachably installed in the rotary mounting base, which is rotatably disposed on the left side wall of the splitter plate. The outer peripheral side wall of the rotary mounting base is provided with a first toothed ring.

[0017] In the above-mentioned automatic stranding device for aluminum stranded cables, the drive unit two includes two independently rotatable second toothed rings, which are used to drive the rotating mounting bases of the inner and outer rings respectively, and the second toothed rings mesh with the first toothed rings.

[0018] The aforementioned automatic stranding device for aluminum stranded cables also includes a controller, which is communicatively connected to the fluctuation detection module, the auxiliary tensioning module, and the deflection adjustment module.

[0019] Compared with existing technologies, the advantages of this invention are: this invention achieves intelligent coordinated tensioning and precise online compensation for tension imbalance in the twisting of different diameter monofilaments, and significantly improves product consistency, process adaptability and production continuity through the guide ring self-refreshing mechanism.

[0020] 1. An intelligent collaborative tensioning strategy is provided for stranding monofilaments of different diameters, simplifying the machine setup process and enhancing process adaptability. During the initialization phase, based on pressure data fed back by the fluctuation detection module, the controller identifies the initial pressure difference between the inner and outer monofilaments due to their different diameters. It then instructs the auxiliary tensioning module to perform batch, collaborative compensation tensioning of the outer coarser filament until the pressure of the inner and outer monofilaments on the detection arc plate reaches dynamic equilibrium. This process is automated, eliminating the need for repeated manual trial and error, simplifying the setup of stranding monofilaments of different diameters, shortening changeover time, and enabling the equipment to more flexibly and efficiently adapt to the production needs of various product specifications.

[0021] 2. By installing a fluctuation detection module on the outlet side of the splitter plate, a pressure sensor directly monitors the real-time "wall-attachment" state of each filament before entering the final stranding point, converting tension imbalance into a quantifiable electrical signal. When an abnormality is detected, the auxiliary tensioning module can quickly apply a radial supplementary tension to the filament in the abnormal loop, rapidly restoring it to the correct position. This achieves real-time online detection and precise compensation of tension imbalance, significantly improving product quality and consistency.

[0022] 3. When the controller determines that the abnormal tension is caused by wear of the guide ring, the deflection adjustment module automatically drives the guide to rotate around its axis by a certain angle (such as 90° or 180°), switching the unworn or lightly worn arc segment to the working position, realizing the "self-refreshing" of the guide working surface, extending the life of the guide ring by several times, and transforming unplanned downtime replacement into predictable maintenance operations that can be completed during production breaks, significantly improving the continuity and stability of production.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0033] Reference Figures 1 to 2 An automatic stranding device for aluminum stranded cables includes a frame 1, a stranding cage 2, a forming die 3, a support column 4, a tension control system (not shown in the figure, which is prior art and a conventional configuration in the field), a conductor separator 5, and an online stranding status control system. The online stranding status control system includes a fluctuation detection module 6, an auxiliary tensioning module 7, and a deflection adjustment module 8, which are communicatively connected to the fluctuation detection module 6, the auxiliary tensioning module 7, and the deflection adjustment module 8 via a controller (not shown in the figure).

[0034] Frame 1 serves as the supporting foundation for the entire equipment. The winding cage 2 (i.e., the rotating cage of the tubular stranding machine) is mounted on frame 1, and its interior houses multiple wire feeding reels (see reference). Figure 1 The forming die 3 is fixed to the frame 1 by a die base and is located at the right end of the auger 2 (i.e., the exit direction). A wire separator 5 is fixedly installed on the right exit side of the auger 2 by a support column 4. The wire separator 5 is located on the left side of the forming die 3. The wire separator 5 has multiple rings of through holes arranged in a circular pattern according to the stranded wire structure (such as 6 wires, 12 wires, etc., 12 wires are used in this case). In this case, there are six through holes in the inner ring and six through holes in the outer ring, which are staggered. A guide ring 51 is installed in each through hole. The guide ring 51 is made of ceramic. The position where the guide ring 51 contacts the monofilament is chamfered. After each monofilament is led out from the wire feeding reel of the auger 2, it passes through the corresponding guide ring 51 and finally converges and is stranded at the forming die 3.

[0035] Reference Figure 2 and Figure 6 The fluctuation detection module 6 is located on the right side wall of the splitter plate 5 and includes a support ring (not separately labeled in the figure) fixed to the right side wall of the splitter plate 5. A spring rod 61 is installed on the support ring at a radially inner position corresponding to each guide ring 51. A detection arc plate 62 is installed at the movable end of the spring rod 61, and the surface of the detection arc plate 62 is perpendicular to the travel direction of the monofilament. A miniature pressure sensor (such as a thin-film pressure sensor, not shown in the figure) is attached to the inner side of the arc surface of the detection arc plate 62 (the side attached to the corresponding monofilament). The detection end of each pressure sensor corresponds one-to-one with the radially inner position of each guide ring 51.

[0036] Under ideal conditions, with normal tension and the monofilament tightly adhering to the inner wall of the guide ring 51 (near the center), the monofilament will slightly press against the detection arc plate 62, and the pressure sensor will output a stable reference signal. If a monofilament experiences radial "relaxation" due to tension slack, its pressure on the detection arc plate 62 will decrease or even disappear. The pressure sensor converts this change in contact force into an electrical signal in real time, which is then output as a detection signal.

[0037] Reference Figure 2 The auxiliary tensioning module 7 is mounted on the support column 4 and located to the left of the dividing plate 5. The auxiliary tensioning module 7 includes a drive unit 71 and a tensioning unit 72.

[0038] Reference Figures 2 to 5The tensioning unit 72 includes a support plate 721 fixed to the support column 4 and a disassembly plate 722 mounted on the support plate 721. Both the support plate 721 and the disassembly plate 722 are detachable structures (left cover and right box). Multiple radial grooves are formed on both the support plate 721 and the disassembly plate 722, and a tensioning slider 723 is slidably mounted in each groove via a spring (not shown). A hook 724 for hooking the corresponding monofilament is fixed to the tensioning slider 723 away from the axis of the support column 4. The hook 724 on the support plate 721 corresponds to the guide ring 51 of the inner ring on the dividing plate 5, while the hook 724 on the disassembly plate 722 corresponds to the guide ring 51 of the outer ring. A driven wedge 725 is also fixedly connected to the side wall of the tensioning slider 723.

[0039] Reference Figures 2 to 5 The drive unit 71 includes two drive discs 711 that can slide left and right on the support column 4 via electric sliders. The two drive discs 711 are respectively positioned corresponding to the support disc 721 and the disassembly disc 722. Each drive disc 711 has multiple connecting rods 712 evenly distributed circumferentially on its right side, and a wedge-shaped head 713 is fixed on the connecting rod 712. The inclined surface of the wedge-shaped head 713 cooperates with the inclined surface of the driven wedge 725 on the tension slider 723 to drive the driven wedge 725 and the tension slider 723 to move in a direction closer to the axis of the support column 4.

[0040] Reference Figure 2 and Figure 8 The deflection adjustment module 8 is located on the left side wall of the dividing plate 5. The deflection adjustment module 8 includes a drive unit 81 and a rotary mounting base 82. A guide ring 51 is detachably engaged within the rotary mounting base 82. The rotary mounting base 82 is rotatably fitted into the through hole of the dividing plate 5 via bearings. A first toothed ring 821 is provided on the outer peripheral side wall of the rotary mounting base 82. The drive unit 81 includes two second toothed rings 811. An arc-shaped slide rail (not shown in the figure) is provided on the left side wall of the dividing plate 5. The second toothed rings 811 slide circumferentially within the arc-shaped slide rail via an electric slider. The two second toothed rings 811 respectively drive the inner and outer rings of the rotary mounting base 82, and the second toothed rings 811 mesh with the first toothed rings 821.

[0041] The production stages of aluminum stranded cable strands include the first stage (system initialization and benchmark establishment), the second stage (normal stranding and online monitoring), the third stage (abnormal detection and primary compensation), and the fourth stage (secondary compensation and wear management).

[0042] The specific operation of the first stage (system initialization and benchmark establishment) is as follows: First, threading and pre-tensioning are performed. The operator leads out the single wires on each wire feeding reel and passes them through the corresponding hook 724 on the auxiliary tensioning module 7 and the corresponding guide ring 51 on the wire separating plate 5 in sequence. The single wires are then placed against the detection arc plate 62 of the fluctuation detection module 6. Finally, all the single wires are gathered and introduced into the forming mold 3.

[0043] The device is then started at low speed, and the existing tension control system (located at the pay-off end) provides each monofilament with basic tension. At this time, each monofilament, under tension, adheres tightly to the inner side of its respective guide ring 51 (near the axis of the support column 4). The controller begins to collect signals from the pressure sensors on each detection arc plate 62. This includes the following two cases: For monofilaments of the same diameter: the controller calculates and records the average value of the output pressure of each sensor at this time, sets this value as the reference pressure value for this batch of production, and allows a small tolerance range. It should be noted that when the basic tension of monofilaments of the same diameter is consistent, the output pressure values ​​of each sensor are nearly identical.

[0044] In the case of unequal diameter monofilaments (taking the case where the inner guide ring 51 introduces a thinner filament and the outer guide ring 51 introduces a coarser filament as an example): the controller calculates and records the average output pressure of each sensor in the inner ring and the average output pressure of each sensor in the outer ring at this time. The pressure sensor feeds back to the controller, and the controller issues a command to assist the tensioning module 7 in performing batch circumferential adjustment of the outer ring coarser filament, so as to further compensate for the tension of the coarser filament on the basis of the basic tension, and unify the average pressure of the thinner and coarser filaments.

[0045] Specifically, the drive disc 711 corresponding to the coarse filament moves to the right, pushing the connecting rod 712 and wedge head 713 on it. Through the inclined surface engagement, the wedge head 713 pushes the driven wedge block 725 of the outer ring, thereby driving the corresponding tensioning slider 723 to slide along the groove towards the center. The hook 724 then pulls the hooked outer ring coarse monofilament, applying a radially inward auxiliary tension to keep it in close contact with the inner wall of the guide ring 51 (e.g., Figures 6 to 7 When the pressure of the inner ring fine monofilament is equal to the average pressure, the pulling stops. This eliminates the need for repeated manual trial and error, simplifying the setup of the machine for twisting different diameters, shortening changeover time, and enabling the equipment to more flexibly and efficiently adapt to the production needs of various product specifications.

[0046] When all pressure signals stabilize, the controller determines that the "initial tension equilibrium state" has been established, allowing the device to accelerate to normal production speed.

[0047] The second stage (normal stranding and online monitoring) is as follows: The device enters production mode. The winch 2 rotates, and the traction machine pulls out the strand at a constant speed. Ideally, each monofilament slides stably along the inner wall of the guide ring 51 under the balance of centrifugal force, wire tension, and traction force, maintaining a constant pressure on the detection arc plate 62, and the sensor signal is stable. The controller continuously scans the data stream of all pressure sensors at a millisecond frequency and compares it with the set expected range.

[0048] The third stage (anomaly detection and primary compensation) is as follows: During production, once the controller detects that the signal value of any pressure sensor deviates from its expected range (for example, a sudden drop in pressure indicates that the monofilament has loosened and detached), it immediately determines that the corresponding monofilament has a tension imbalance. Within milliseconds, the controller completes the following actions: based on the sensor number, it determines whether the abnormal monofilament belongs to the inner or outer coil.

[0049] A pulse command is sent to the corresponding drive unit 71 (inner or outer ring drive disk 711) in the auxiliary tensioning module 7. Upon receiving the command, the electric slider drives the corresponding drive disk 711 to move to the right. The connecting rod 712 on the drive disk 711 moves accordingly, and the wedge head 713 pushes the driven wedge block 725 through the inclined surface. The driven wedge block 725 drives the tensioning slider 723 to slide rapidly towards the center along the radial groove of the support disk 721 or the disassembly disk 722. The hook 724 on the slider then hooks the monofilaments of the corresponding outer or inner ring in batches, applying an instantaneous, radially inward additional tension. This action forces the loosened monofilaments to re-adhere to the guide ring 51, realizing real-time online detection and precise compensation of tension imbalance, significantly improving product quality and consistency.

[0050] It is important to note that after the tensioning action is completed, the controller immediately reads the pressure sensor signal at that location again. If the signal returns to the expected range within a short time, the first-level compensation is considered successful. This fine-tuning does not affect the overall production continuity.

[0051] The fourth stage (secondary compensation and wear management) is as follows: If the abnormal signal is still not restored after the first-level auxiliary tension compensation is performed, the controller will determine that the root cause of the problem may be the uneven wear of the inner wall of the guide ring 51 (when the single wire passes through the dividing plate 5, it is in a tapered and gradually narrowing state, which makes it easy to twist the wire into the forming mold 3 and tighten it. However, the tapered and gradually narrowing state will cause the single wire to stick to the local area of ​​the guide ring 51 near the center of the dividing plate 5. Long-term close contact transmission will lead to local wear and grooves), which will cause the single wire to be unable to obtain stable and continuous support.

[0052] The controller then sends a command to the corresponding drive unit 81 (the second gear ring 811 controlling the inner or outer ring) in the deflection adjustment module 8. The electric slider drives the second gear ring 811 to deflect, and through gear meshing, drives the target rotating mounting base 82 and its internal guide ring 51 to rotate around its own axis by a set angle (e.g., 90° or 180°). This displaces the worn groove portion out of the working area and rotates the relatively smooth arc segment to the position of contact with the monofilament, realizing the "self-refreshing" of the guide working surface. After the guide ring 51 rotates, the monofilament can regain stable contact under the new contact surface, and the signal tends to be stable. This restores the uniform guiding effect of the inner wall of the guide ring 51, extends its overall service life, avoids frequent downtime for replacement, and transforms unplanned downtime for replacement into predictable maintenance operations that can be completed during production breaks, significantly improving the continuity and stability of production.

[0053] Ultimately, all the single filaments maintain a precisely designed, consistent radial position and stable tension when entering the forming die 3. This allows them to achieve a perfect geometric fit when stranded in the forming die 3, resulting in aluminum stranded cables with extreme roundness, tight structure, uniform pitch, and high-quality characteristics such as no back strands and no loose strands. At the same time, it significantly reduces downtime and product scrap caused by tension issues.
