Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing equipment technology, and specifically to a cable-forming synchronous stranding auxiliary device for providing support and guidance for core wires in the cable-forming process, particularly in multi-section stranding equipment. Background Technology

[0002] With the development of fast charging technology for electric vehicles, high-power liquid-cooled charging cables have been widely used. Compared with traditional cables, liquid-cooled cables, in addition to integrating power lines and signal lines, also require built-in independent cooling pipes. This structure makes the cable core increasingly complex, specifically manifested in a significant increase in the number of core wires, a higher proportion of irregular components (such as liquid-cooled pipes), and special requirements for the spatial arrangement of the core wires.

[0003] In the cabling process, multi-section winch equipment is often used to achieve orderly stranding of the core wires. For liquid-cooled cables with special structures, it is usually necessary to arrange the core wires with large cross-sections and high rigidity, such as power wires and liquid cooling pipes, in the second section of the winch, while the remaining core wires are supplied by the third section of the winch. However, there is a gap of about 10 meters between the synchronization tubes of the second and third sections of the winch, which causes the core wires drawn from the second section of the winch to be in a free and unsupported state within this section.

[0004] When the two sections of the winch rotate synchronously and in the same direction, the core wires (especially the power wires and liquid cooling pipes) in this section naturally sag under gravity and oscillate with the rotation of the equipment, making them extremely prone to interference, entanglement, and even knots. This not only damages the insulation layer or tube body of the core wires, leading to product scrap, but may also cause unplanned equipment downtime due to wire jamming or breakage, seriously affecting production continuity. To solve these problems, the existing process has to rely on operators to manually monitor and intervene in this area, which not only increases labor costs but also makes it difficult to guarantee the stability of production efficiency and quality. Utility Model Content

[0005] The purpose of this invention is to provide a cable-forming synchronous stranding auxiliary device, which provides stable support and guidance for long-distance suspended core wires, effectively avoiding problems such as mutual entanglement, swinging and knotting caused by the free suspension of core wires, thereby improving cable-forming efficiency and product quality.

[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0007] A cable-forming synchronous stranding auxiliary device includes a base, a support rod on the base, a fixing plate at the top of the support rod, a bearing in the through hole of the fixing plate, a wire distributor in the inner ring of the bearing, and a plurality of wire-passing holes for core wires to pass through, the plurality of wire-passing holes being evenly distributed along the circumference of the wire distributor.

[0008] Preferably, the fixing plate includes a detachably connected left housing and a right housing. After the left housing and the right housing are docked, their interiors together form a limiting groove for accommodating the bearing. This structure facilitates the installation, maintenance and replacement of the bearing.

[0009] Preferably, the bearing is a deep groove ball bearing, which can simultaneously withstand radial loads and bidirectional axial loads, and has low frictional resistance, high speed, simple structure, and low manufacturing cost, making it suitable for the application scenarios of this device.

[0010] Preferably, on the inlet side of the distributor plate, the edge of the distributor plate has an outwardly extending limiting protrusion ring, which cooperates with the fixed plate or bearing to axially limit the distributor plate and prevent it from coming off during operation.

[0011] Preferably, the number of wire-passing holes provided on the distribution panel is 18, in order to meet the requirements of most liquid-cooled cable core wires.

[0012] Preferably, the cable distribution panel is also provided with a central through hole to allow filler material (such as filler rope) in the center of the cable to pass through, ensuring the integrity of the cable structure.

[0013] Preferably, the support rod includes an outer tube and a lead screw. The lead screw is disposed inside the outer tube and can extend and retract relative to the outer tube. A limit sleeve is threadedly connected to the lead screw. By rotating the limit sleeve, the length of the lead screw extending out of the outer tube can be adjusted and locked, thereby realizing the height adjustment of the entire device.

[0014] Preferably, an auxiliary rod is fixedly provided on the outer peripheral wall of the limiting sleeve. By operating the auxiliary rod, the operator can directly rotate the limiting sleeve without the need for tools such as wrenches, thus improving the convenience and efficiency of the adjustment operation.

[0015] Preferably, the lead screw has an axial groove extending along its axis, and the outer tube has a locating pin that extends into the axial groove. The engagement of the locating pin with the axial groove restricts the lead screw from rotating, allowing it to move only in a straight line, thus ensuring that the upper fixed plate and distributor plate always maintain their preset positions.

[0016] Preferably, the base is provided with multiple through holes, and bolts can be passed through these through holes to firmly fix the entire device to the ground, maintaining the stability of the device during operation.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. Provides stable support and guidance to prevent tangling and knotting: By setting this device in the long suspension area between the second and third sections of the winding cage, a reliable support and guidance point is provided for the core wires. The distributor reel orderly separates the core wires, effectively suppressing their swaying and mutual interference during rotation, fundamentally avoiding tangling and knotting.

[0019] 2. Protects the core wires and improves product quality: It avoids mutual scratching between core wires and collisions with equipment, significantly reducing the risk of damage to the core wire insulation layer or tube (such as liquid cooling tube), thereby improving the quality and pass rate of the final cable product.

[0020] 3. Ensure uniform tension and improve production efficiency: This ensures that the core wire maintains uniform and controllable tension when entering the third section of the winding cage synchronization tube, reducing problems such as wire breakage and machine stoppage caused by uneven tension or wire jamming, ensuring the continuity and stability of the cabling process, and improving overall production efficiency.

[0021] 4. Reduce labor costs and labor intensity: The application of this device can replace or significantly reduce the manual monitoring and intervention required in this area, thereby reducing the labor intensity of operators and the labor costs of enterprises.

[0022] 5. Simple structure and easy adjustment: The overall structure of the device is reasonably designed and has low manufacturing cost. The height of the support rod is adjustable, which can flexibly adapt to different equipment and process requirements. It is easy to operate and highly practical. Attached Figure Description

Detailed Implementation

[0030] like Figures 1 to 5 As shown, a cable-forming synchronous stranding auxiliary device includes a base 1, a support rod, a fixing plate, a bearing 4, and a cable distribution plate 5.

[0031] The base 1 is a square (or round) plate (10mm thick) with through holes 11 at its four corners, allowing the device to be securely installed on the ground using bolts. A triangular reinforcing member 12 is welded between the base 1 and the support rod to enhance structural stability.

[0032] The support rod consists of an outer tube 21 (outer diameter 60mm, inner diameter 40mm) and a lead screw 22 (outer diameter 40mm). The outer tube 21 is fixed to the base 1, and the lead screw 22 is fitted inside the outer tube 21 and can move up and down. An axial groove 221 is formed on the body of the lead screw 22, and a locating pin 25 is inserted through the outer tube 21, with the inner end of the locating pin 25 extending into the axial groove 221. This structure allows the lead screw 22 to slide up and down along the axial groove 221, but it cannot rotate.

[0033] A limiting sleeve 23 (or nut) is threaded onto the lead screw 22. Two auxiliary rods 24, which serve as operating handles, are welded to the outer wall of the limiting sleeve 23. When the height needs to be adjusted, the limiting sleeve 23 can be rotated by moving the auxiliary rods 24, thereby driving the lead screw 22 to rise or fall. After adjustment, the limiting sleeve 23 is supported at the end of the outer tube 21, thus achieving locking.

[0034] A fixed plate (300mm in diameter, 250mm in inner diameter, and 40mm in thickness) is fixedly mounted on the top of the lead screw 22. The fixed plate is formed by bolting together a left housing 31 and a right housing 32, creating an annular limiting groove 33 between them. A deep groove ball bearing 4 (250mm in outer diameter and 210mm in inner diameter) is installed within this limiting groove 33. This structure facilitates the installation and replacement of the bearing 4.

[0035] The distributor 5 (outer diameter 210mm) is press-fitted into the inner ring of the deep groove ball bearing 4, allowing it to rotate freely relative to the fixed disc. A limiting protrusion 52 is provided along the edge of the distributor 5 on its inlet side (i.e., the side facing the second section of the winch). This limiting protrusion 52 engages with the inner ring side of the bearing 4 to prevent the distributor 5 from axially moving towards the third section of the winch. Alternatively, the distributor 5 can be fixed to the inner ring of the deep groove ball bearing 4 using other common methods, such as adhesive bonding or welding.

[0036] like Figure 1 , 2As described in section 4, the cable distributor 5 has 18 wire-passing holes 51 (20mm in diameter) evenly distributed around its circumference for guiding and separating the core wires. A central through-hole 53 (130mm in diameter) is also provided in the center of the cable distributor 5 for the passage of the cable's central filler rope. The cable distributor 5 is made of nylon PA66, which features high strength, high hardness, low coefficient of friction, and good fatigue resistance.

[0037] The working principle of this utility model is as follows:

[0038] During installation, adjust the total height of the support rod by rotating the limiting sleeve 23 according to the actual height of the production line, so that the distribution plate 5 is at a suitable working height. Fix the device to the ground via the base 1, ensuring that it is located in a suitable working position between the second and third sections of the auger. Then, thread each core wire (such as power wire, liquid cooling pipe, etc.) from the second section of the auger through the corresponding wire holes 51 on the distribution plate 5 according to the preset arrangement, and thread the central filling rope (if any) through the central through hole 53.

[0039] When the cabling equipment starts, the two sections of the winch rotate synchronously in the same direction, pulling the core wire forward and causing it to twist. Because the core wires are effectively separated by the separator 5, they will not contact or tangle with each other over the long suspension section. Simultaneously, the core wires drive the separator 5 to rotate along with them on the bearing 4. This "follow-up" design greatly reduces the relative friction and resistance between the core wires and the device, protecting the surface of the core wires and ensuring the uniformity of the twisting tension.

[0040] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
