Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy conductor stranding processing, in particular to an aluminum alloy conductor stranding and pressing device based on cable production. Background Art

[0002] The significance of twisting aluminum alloy conductors is to twist multiple aluminum alloy single wires according to specific rules, which significantly improves the comprehensive performance of the conductor. The twisted structure can greatly enhance the mechanical strength and flexibility of the conductor, improve the tensile strength to adapt to complex environments, make the conductor structure tight and stable, avoid loose single wires, and ensure the reliability of electrical connections. At the same time, it also improves material utilization by flexibly adjusting the single wire specifications, giving aluminum alloy conductors light weight, corrosion resistance, high strength and other characteristics, and is widely used in power transmission, building wiring and other fields.

[0003] Traditional cable twisting and compacting equipment relies solely on static tension wheels or counterweights for tension control, and is unable to dynamically compensate for changes in cable length during the reciprocating movement of the winding reel, resulting in alternating periodic relaxation and over-tightening. This significantly increases the risk of wire jumpers and requires frequent manual intervention. At the compacting process level, it only provides one-way vertical compression, which cannot cover the entire circumference of the cable, resulting in excessive outer diameter ovality, residual core gaps, and unstable twisting pitch. Furthermore, there is a lack of orderly guidance for the twisted cables, leading to chaotic multi-wire convergence paths. Summary of the Invention

The transverse rail is fixed to the end of the mounting frame, and the sliding frame is slidably connected to the transverse rail via an I-shaped slider fixedly connected at the bottom. The bottom of the I-shaped slider is fixedly connected to a directional column, and a cover is fixedly installed at the bottom of the mounting frame via a pad.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. When in use, the present invention significantly improves the quality and efficiency of cable production through the synergistic effect of the dynamic tensioning control system and the multi-directional dynamic compression assembly. The dynamic tensioning control system uses a worm gear transmission mechanism and a connecting rod swing rail design to convert the motor's rotational motion into reciprocating lateral movement of the sliding frame. The first and second guide wheels compensate for cable slack caused by changes in payout distance in real time, eliminating the risk of wire jumpers and stabilizing tension. This allows precise adjustment of tension without manual intervention, reducing equipment wear and extending maintenance cycles, while also improving the stability and efficiency of the production process. 2. The multi-directional dynamic pressing component converts the motor's rotational motion into a composite trajectory motion of an arc-shaped pressing frame through an eccentric drive and linkage frame mechanism, and performs multi-directional dynamic pressing on the surface of the twisted cable. The component forms a continuous pressing cycle through the superposition of horizontal and vertical movements, effectively eliminating the gaps between the wire cores and optimizing the twisted structure, making the cable surface smooth and the outer diameter roundness significantly improved. The synergistic effect of multiple sets of pressing frames ensures that the pressing force evenly covers the entire circumference of the cable, significantly enhancing the compactness and mechanical strength of the conductor structure, while reducing the risk of insulation layer damage due to stress concentration, ultimately improving the electrical performance of the cable and the qualified rate of finished products.

[0018] Embodiment 2: A cable bundle reel 8, a stranding machine 9, and a vertical support plate 10 are fixedly mounted on the top of the frame. The side walls of the vertical support plate 10 are provided with multiple sets of pressing components. It should be noted that the stranding machine 9 is an existing device. Its main function is to twist multiple metal cables together according to certain rules through rotation and tension control to form a cable core with stable structure and good conductivity.

A material passing groove 1 is provided at the center of the cable bundle drum 8, and a material passing groove 2 corresponding to the number of the mounting frame 3 is provided on the outside of the cable bundle drum 8.

[0020] Combining the first and second embodiments, it can be seen that the working principle of the present invention is as follows: 1. Initial Preparation Phase Before starting the device, the loading and positioning are carried out: the aluminum alloy wire cores are respectively wound on the winding reels 4 of the loading tray 2. The loading tray 2 is provided with multiple sets of mounting frames 3 arranged in a circular array with the center as the axis. The winding reels 4 are installed inside each set of mounting frames 3. The center wire core passes through the center feed slot 1 of the loading tray 2 and the bundled wire tray 8 to ensure that the wire core extends along the central axis of the equipment; Path planning: Two material troughs corresponding to the number of mounting brackets 3 are opened on the outside of the cable tray 8 to guide the cables released by multiple winding reels 4 to converge to the center to avoid cable crossing or entanglement; Equipment standby: The stranding machine 9 is in a stopped state, the pressing assembly on the vertical support plate 10 is not activated, and the entire device enters a standby state; 2. Cable Pay-off and Tension Control All the winding reels 4 actively release the cables under the action of external drive. After being deflected by the guide wheels 1 and 2 7 at the ends of the mounting frame 3, the cables converge toward the center of the cable tray 8. The layout of the guide wheels 1 and 2 7 ensures that the cables remain stable during movement and avoids deviation caused by centrifugal force. 3. Tightness Control Component Dynamically Compensates for Relaxation Once the motor is powered on, it drives the worm 505 to rotate at high speed. The meshing transmission between the worm wheel 504 and the worm 505 converts the high-speed rotation into the low-speed rotation of the worm wheel 504, thereby achieving deceleration and torque increase. Reciprocating motion transmission: The worm gear 504 pushes and pulls the drive plate 508 through the connecting rod 509. The drive plate 508 drives the rotating shaft 506 to swing back and forth in the housing 6. The swing angle of the rotating shaft 506 is determined by the number of teeth of the worm gear 504 and the lead of the worm 505, ensuring that the stroke of the sliding frame 502 matches the maximum slack of the cable; Transverse displacement conversion: The swing rail 507 at one end of the rotating shaft 506 swings with the rotating shaft 506. The swing groove on its outer side cooperates with the protrusion at the bottom end of the directional column 503, forcing the I-shaped slider to slide back and forth along the transverse rail 501. The length of the transverse rail 501 is designed to cover the pay-off distance from the center to the farthest point of the winding reel 4, ensuring sufficient tension adjustment range; Real-time adjustment of the tensioning force: When the sliding frame 502 moves with the I-type slider, a lateral pulling force is applied to the cable through the guide wheel 1 and the guide wheel 2 7. When the wire winding reel 4 is at its farthest position, the guide wheel 2 7 moves toward the midpoint of the transverse track 501 to increase the cable tension. When the wire winding reel 4 moves in the opposite direction, the guide wheel 2 7 moves synchronously to prevent the cable from slacking. This process is dynamically compensated by the closed-loop speed control of the motor 1, ensuring that the cable is always in the optimal tension state. 4. Twisting and pressing to shape Multi-cable stranding and fusion of the center core: After multiple aluminum alloy cables and the center core are combined at the center of the cable bundle 8, they enter the stranding chamber of the stranding machine 9. The stranding machine 9 twists the multiple cores into a compact conductor structure through rotary stranding. The stranding pitch is set by the equipment parameters. At this time, the stranded conductor still has uneven stress and outer diameter deviation, which requires further processing through the compression assembly. 5. Dynamic pressing process of compacted components Eccentric drive mechanism: When the second motor is powered on, it drives the eccentric block 134 to rotate. The eccentric block 134 makes a circular motion in the deflection groove around the fixed axis. The eccentric distance of the eccentric block 134 determines the horizontal stroke of the linkage frame 2 135, ensuring that the pressing force covers the fluctuation range of the cable outer diameter. Horizontal reciprocating motion: The eccentric block 134 pushes the linkage frame 135 through the linkage block 136. The linkage frame 135 drives the frame rail 131 to slide horizontally and reciprocatingly along the slide rod 11. The length of the slide rod 11 is designed to meet the compression requirements of the maximum outer diameter of the cable, ensuring that the compression area is fully covered; Vertical displacement superposition: The swing block 133 drives the linkage frame 132 through the linkage block 1. The linkage frame 132 slides up and down along the vertical rod in the frame rail 131. The height of the vertical rod determines the pressing depth of the arc-shaped pressing frame 137, ensuring that the pressing force is evenly transmitted to the cable surface. Rectangular trajectory movement: The arc-shaped pressing frame 137 forms a rectangular trajectory of "descending → horizontal movement → rising → reverse movement" under the superposition of horizontal and vertical movements. When the cable passes through the pressing area, the arc-shaped pressing frame 137 first presses down on the cable surface, then moves along the cable discharge direction, then rises and separates from the cable, and moves back to the initial position to complete a pressing cycle. Multiple groups of arc-shaped pressing frames 137 are arranged in a circular array to achieve continuous dynamic pressing to ensure the roundness of the cable outer diameter.
