Description

Technical Field

[0001] This invention relates to the field of stranding machine technology, and in particular to a low-torque, high-speed multi-core cable stranding machine. Background Technology

[0002] As a core piece of equipment in the cable processing field, cable stranding machines are mainly used to strand multiple conductor cores to form a cable core, thereby improving the structural strength and electrical performance of the cable. Low-torque high-speed cable stranding machines are an advanced cable manufacturing equipment. Their core design goal is to maximize the protection of the internal structure of the cable and prevent it from being damaged during the production process while maintaining extremely high production efficiency, thereby producing high-quality, high-performance precision cables.

[0003] While existing cable stranding equipment generally has tension adjustment functions, the actual stranding process often involves the mixed use of cores of different materials. Due to the differences in physical properties such as elastic modulus, tensile strength, and coefficient of thermal expansion of different core materials, their sensitivity to tension fluctuations varies. Relying solely on a single overall tension adjustment mechanism makes it difficult to achieve precise matching and differentiated control for the independent tension requirements of each core, thereby affecting the structural uniformity and finished product quality of the stranded cable. Therefore, a low-torque, high-speed multi-core cable stranding machine is proposed. Summary of the Invention

[0006] As a preferred embodiment of the present invention, the adjustment mechanism includes a wire harness disk disposed between the adjustment disk and the guide cylinder, and a reinforcing plate is disposed inside the wire harness disk; An adjusting rod is also fixed to the side of the fixed rod near the adjusting plate, and the middle of the adjusting plate has several spiral grooves to facilitate the movement of the adjusting rod. The output shaft of the servo motor drives the adjustment disk to rotate. The spiral groove in the middle of the adjustment disk cooperates with the adjustment rod, causing the adjustment rod to move from the middle of the adjustment disk to the edge of the adjustment disk. The adjustment rod drives the fixed rod to move from the middle of the adjustment disk to the edge of the adjustment disk. The fixed rod drives the guide block to move away from the adjustment disk. The guide block drives the wire harness tube to move away from the adjustment disk. The wire harness tube adjusts the tension of the wire core passing through the inlet hole.

The outer wall of the limiting rod is also provided with a scale. Rotating the lead screw engages with the threaded hole of the guide block, causing the lead screw to move the wire harness tube vertically up and down, adjusting the distance between the wire harness tube and the guide block. The wire harness tube then moves the wire core passing through the inlet hole vertically up and down, adjusting the distance between the wire core and the guide block, thereby adjusting the tension of a single wire core.

[0010] As a preferred technical solution of the present invention, a plurality of positioning holes for positioning the wire core are also provided at the edge of the wire bundle, and a plurality of wire clamping balls are provided inside the plurality of positioning holes. The clamping ball is rotatably installed inside the positioning hole, and the clamping ball is made of rubber material.

[0011] As a preferred embodiment of the present invention, two inclined plates are also hinged between the transmission ring and the guide cylinder, and a slider is hinged to the end of the inclined plate away from the transmission ring.

Rotating the threaded rod causes it to engage with the threaded hole in the slider, allowing the threaded rod to move laterally along the inside of the groove. The slider drives the transmission ring to move laterally via the inclined plate. The transmission ring drives the positioning ring to move laterally via the extension rod. The positioning ring drives the fixing rod to move laterally. The fixing rod drives the adjusting plate and the guide block to move laterally. The guide block drives the wire harness tube to move laterally, adjusting the distance between the wire harness tube and the wire harness disc, thereby simultaneously adjusting the tension of several wire cores.

[0012] As a preferred technical solution of the present invention, a rod is fixed on one side of the two inclined plates facing each other, and the two rods are connected to a limiting cylinder on the same side. A limiting hole adapted to the rod is opened in the middle of the limiting cylinder. The transmission ring is provided with a main connecting rod on the side near the guide cylinder, and a secondary connecting rod is provided on the outer wall of the slider. The inclined plate is rotatably connected between the main connecting rod and the secondary connecting rod. The end of the insert rod away from the inclined plate is inserted into the limiting hole. The inclined plate is limited by the cooperation of the insert rod and the limiting cylinder, so that the two inclined plates drive the transmission ring to move laterally at the same time.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: This invention, through the cooperation of structures such as a wire harnessing mechanism, servo motor, adjustment disc, fixing rod, guide block, wire harness tube, and positioning ring, can not only set the tension uniformly for multiple wire cores to ensure the consistency and stability of the stranding process, but also make independent fine adjustments for a single wire core, effectively compensating for differences in wire diameter, material, and stress between wire cores, avoiding problems such as wire core stretching, loose strands, and broken strands caused by uneven tension, and significantly improving the roundness and forming quality of cable core stranding; This invention, through the cooperation of structures such as guide blocks, wire bundle tubes, limiting rods, and lead screws, enables precise and quantitative adjustment of tension parameters when adjusting the wire core individually or when performing individual tension adjustment operations on a single wire core, relying on the scale set on the outside of the limiting rod. This further improves the wire core tension adjustment accuracy, ensures that the tension distribution of each wire core is uniform and reasonable, and significantly improves the cable core forming accuracy and product consistency under low torque high speed stranding conditions. This invention utilizes the cooperation of structures such as a fixed rod, guide block, positioning sleeve, connecting rod, and blocking plate to simultaneously enlarge or shrink the ring constraint structure formed by the guide block, positioning sleeve, and connecting rod. This allows for flexible adaptation to the processing requirements of wire cores with different diameters and strand numbers. Specification switching can be completed quickly without changing the corresponding tooling, significantly improving equipment versatility and production changeover efficiency. It also effectively avoids problems such as wire core scratches and stranding eccentricity, thereby improving the quality of cable core forming and processing stability. This invention utilizes the cooperation of structures such as guide blocks, positioning sleeves, connecting rods, and blocking plates. By using the blocking plate and positioning sleeve together to form a limiting constraint on the connecting rod, the movement of the guide blocks during the adjustment process can be effectively limited. This avoids problems such as wire core detachment from constraints and wire deviation caused by excessive adjustment of the guide block spacing. It ensures that the wire core is always within a stable constraint range during the stranding process, further improving the operational reliability of high-speed stranding, reducing faults such as wire core scattering and stranding eccentricity caused by uncontrolled guide block spacing, and ensuring continuous and stable operation of the low-torque high-speed stranding machine. This invention achieves stable clamping and reliable positioning of the wire core through the cooperation of structures such as wire bundle tube, wire bundle disc and wire clamp ball. It can not only ensure smooth and fast movement of the wire core during the stranding process and improve the stranding conveying efficiency, but also effectively suppress the shaking and deviation of the wire core during high-speed stranding, avoid problems such as loose stranding and eccentricity caused by wire core movement, further optimize the routing stability under low torque high-speed stranding conditions, and ensure the stranding quality of the cable core. This invention utilizes a combination of structures such as a guide cylinder, transmission ring, limiting cylinder, threaded rod, slider, inclined plate, and insertion rod to achieve secondary synchronous tension adjustment of multiple wire cores. This forms a two-level coordinated control with the front-end tension adjustment mechanism, further ensuring uniform and consistent overall tension of the multiple wire cores. It effectively compensates for the insufficient precision of single adjustment, making the tension state of the wire cores more stable and controllable before entering the stranding process. This significantly reduces the stress fluctuation of the wire cores during high-speed stranding, better adapts to low-torque high-speed stranding conditions, and improves the straightness of the cable core stranding and the overall performance of the finished cable.
