Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing technology, specifically to a coaxial cable aluminum foil pressing device for processing the shielding layer of coaxial cables, and in particular to a device that achieves efficient pressing of aluminum foil and cable through multi-stage pressing and modular structure. Background Technology

[0002] In the manufacturing process of coaxial cables, longitudinal braiding of aluminum foil is a key process for forming the cable shielding layer. This process requires the aluminum foil to be wrapped flat and evenly over the cable core, avoiding problems such as wrinkles, unevenness, or loose overlaps. Otherwise, it will directly affect the cable's shielding effectiveness, electrical performance (such as return loss), and long-term reliability.

[0003] The currently widely used aluminum foil longitudinal wrapping technology still has many limitations. For example, taking Chinese utility model patent CN209133268U as an example, it discloses an aluminum foil longitudinal wrapping braiding mold for coaxial cables. The mold body is cylindrical, with an axially penetrating longitudinal wrapping hole in the center. The entrance of the longitudinal wrapping hole has a rounded corner, and the exit has a protruding smooth end. The cross-section of the longitudinal wrapping hole has a tapering angle of 5-10°. This structure wraps the aluminum foil through a single longitudinal wrapping channel, which improves the guidance and exit flatness to some extent, but still has the following obvious defects in use: First, the lamination process is simplistic and lacks deformation buffering and gradual adjustment mechanisms. Current technology employs a single longitudinal perforation structure, where the bending, wrapping, and shaping of the aluminum foil are completed in a single process, lacking gradual guidance and control over the plastic deformation of the aluminum foil. In actual high-speed production, the aluminum foil is highly susceptible to micro-wrinkles, cracks, and even breakage due to sudden stress concentration, especially when processing thicker aluminum foil or core wires with varying diameters.

[0004] Secondly, the monolithic structure leads to poor adaptability and high maintenance costs. The mold is a non-removable, one-piece structure with fixed angles and dimensions of its longitudinal wrapping holes, making it impossible to flexibly adjust to different aluminum foil materials, thicknesses, or wire core diameters. When maintenance is required inside the mold due to wear or accumulation of aluminum foil debris, the entire mold must be replaced, increasing spare parts costs and resulting in longer production downtime.

[0005] Secondly, the installation and positioning method is simple, but its vibration resistance and anti-loosening capabilities are insufficient. The mold relies solely on the threads on the outer periphery and the inner steps for installation and axial positioning, lacking an effective radial locking mechanism. Under the continuous vibration of high-speed braiding equipment, the mold is prone to micron-level displacement or loosening. This micro-movement directly leads to asymmetrical aluminum foil coverage and unstable overlap width, thus severely affecting the uniformity of the shielding layer.

[0006] Finally, there is a lack of independent path guidance for the aluminum foil and wire core before they merge. The existing mold only focuses on the wrapping process after merging, without providing independent positioning and guidance for the aluminum foil and wire core before merging. There may be an initial positional deviation between the two before entering the longitudinal wrapping hole. This inherent misalignment directly leads to the subsequent wrapping skew, affecting the initial roundness of the product.

[0007] In summary, existing aluminum foil longitudinal weaving dies require improvement in terms of structural flexibility, process stability, ease of maintenance, and wrapping accuracy. Therefore, a novel pressing device is urgently needed to address these shortcomings. Utility Model Content

[0008] In view of the shortcomings of the above-mentioned background technology, the technical problem to be solved by this utility model is to provide a coaxial cable aluminum foil pressing device that can realize the progressive, multi-stage pressing of aluminum foil onto the wire core, effectively eliminating wrinkles and stress concentration during the wrapping process; at the same time, the device should have modular and adjustable features to adapt to different process requirements, and have a reliable locking and anti-loosening mechanism to ensure stability and wrapping accuracy in high-speed production.

[0009] To address the aforementioned problems, this utility model provides a coaxial cable aluminum foil pressing device, comprising a fixed base and an aluminum foil cable pressing component, wherein the aluminum foil cable pressing component is rotatably connected to the fixed base, and the aluminum foil cable pressing component includes: A convergence guide mechanism is used to guide aluminum foil and cables to a predetermined path and perform initial pressing; The primary pressing mechanism is fixedly installed at the output end of the converging guide mechanism and is used to perform the initial shaping of the aluminum foil-covered cable. The secondary pressing mechanism is detachably connected to the primary pressing mechanism and is used to perform a secondary pressing on the aluminum foil cable after the initial shaping. A locking and fixing mechanism is sleeved outside the secondary pressing mechanism and is used to lock the aluminum foil cable pressing component as a whole onto the fixing base.

[0010] Preferably, the converging guiding mechanism includes: a tapered aluminum foil channel, the cross-section of which gradually decreases along the aluminum foil's travel direction, used to achieve initial wrapping and pressing of the cable by the aluminum foil; a cable inlet tube, fixedly disposed above the aluminum foil channel, used to guide the cable into the aluminum foil channel; a limiting slot positioning plate, disposed above the front end of the aluminum foil channel, used to limit the position of the aluminum foil; and a snap-fit ​​part, disposed on the lower side of the aluminum foil channel, used to snap-fit ​​with the fixed base. By setting independent tapered aluminum foil channels and cable inlet tubes, the converging guiding mechanism ensures precise path guidance and initial pressing of the aluminum foil and the cable core before converging. This design ensures precise spatial alignment of the two from the outset, effectively solving the problem of wrapping misalignment caused by initial positional deviations in existing technologies, and laying a solid foundation for subsequent high-quality pressing.

[0011] Preferably, the primary pressing mechanism includes: a multi-stage step positioning member, which has a pressing channel communicating with the aluminum foil channel inside; and a first connecting structure disposed on the outer periphery of the pressing channel for detachable connection with the secondary pressing mechanism.

[0012] Preferably, the secondary pressing mechanism includes: a secondary positioning component with a tapered pressing cavity inside; and a second connecting structure disposed at the inlet end of the tapered pressing cavity for connecting with the first connecting structure. The primary pressing mechanism and the secondary pressing mechanism form a detachable modular pressing unit via threads. This structure not only achieves two independent shaping processes in the aluminum foil wrapping process, significantly improving the uniformity and tightness of the wrapping, but also allows users to flexibly replace pressing modules of different specifications according to process parameters such as wire diameter and aluminum foil thickness, greatly enhancing the process adaptability of the equipment and overcoming the inherent defects of traditional integral molds that are one-piece and cannot be adjusted.

[0013] Preferably, the locking and fixing mechanism includes: a card holder body with a through-hole limiting cavity; a third connecting structure located at the front end of the card holder body for threaded connection with the fixed base; and at least one tightening screw locking element located on the side wall of the card holder body for radially tightening the secondary positioning element. The locking and fixing mechanism achieves an axial threaded connection with the fixed base through the third connecting structure, and is further radially locked to the secondary pressing mechanism by the tightening screw, forming a unique "axial-radial" dual locking mechanism. This preferred solution greatly enhances the installation rigidity of the entire pressing component under high-speed vibration conditions, effectively prevents micro-movement and loosening, ensures the long-term stability of the aluminum foil overlap width and coverage symmetry, and solves the problem of unstable positioning caused by traditional molds relying solely on a single threaded installation.

[0014] Preferably, the limiting cavity is provided with an axial abutment surface, and the multi-stage stepped positioning component is supported on the abutment surface. The axial abutment surface in the limiting cavity cooperates with the multi-stage stepped positioning component to provide a stable and reliable axial support reference for the entire primary pressing mechanism. This avoids component movement that may be caused by axial force during the pressing process, ensures the relative positional accuracy between the primary and secondary pressing stations, and further guarantees the smooth transition and consistent forming of the aluminum foil from the initial shaping to the secondary pressing.

[0015] Preferably, a reinforced support structure is provided between the limiting slot positioning plate and the primary pressing mechanism. This significantly enhances the structural rigidity and deformation resistance of the front end of the converging guide mechanism under long-term use. This preferred design effectively resists the periodic stress generated during aluminum foil conveying, prevents minor deformation of the positioning plate due to fatigue stress, and maintains the accuracy of the initial aluminum foil insertion position for a long time.

[0016] Preferably, the fixing base is a braiding machine fixing nut, which has a threaded connection part and a snap-fit ​​groove inside, which respectively cooperate with the third connecting structure and the snap-fit ​​part. The internal structure of the braiding machine fixing nut precisely matches the third connecting structure and the snap-fit ​​part. This allows the modular pressing device of this utility model to be quickly and reliably integrated into existing standard braiding machines as a functional component without structural modification of the main machine, greatly improving the versatility and marketability of this technology.

[0017] Preferably, the primary pressing mechanism and the secondary pressing mechanism are connected by threads to form a detachable pressing unit.

[0018] Preferably, the locking and fixing mechanism secures the aluminum foil cable pressing component to the fixing base through a dual method of radial locking and axial threaded connection. The primary and secondary pressing mechanisms connected by threads, along with the dual locking method employed by the locking and fixing mechanism, together constitute the core modularity and high stability features of this utility model.

[0019] Compared with the prior art, the present invention achieves the following beneficial technical effects: This invention achieves progressive multi-stage pressing, effectively eliminating aluminum foil wrinkles and stress concentration, and improving coating quality and electrical performance. Through multi-stage coordination—the initial forming by the converging guiding mechanism, the initial shaping by the primary pressing mechanism, and the final shaping by the secondary pressing mechanism—the aluminum foil coating process is decomposed into multiple progressive stages. This design allows the aluminum foil to deform smoothly and evenly, fundamentally avoiding surface wrinkles, microcracks, and unevenness caused by sudden stress concentration, thereby ensuring the cable's roundness and significantly improving the product's shielding effectiveness and electrical performance.

[0020] This invention adopts a modular and detachable structure, greatly enhancing the adaptability and ease of maintenance of the device, and reducing overall costs. Addressing the shortcomings of existing technologies with fixed structures and inconvenient adjustments, this invention designs the primary and secondary pressing mechanisms to be detachably connected via threads or other means. Users can quickly replace the corresponding pressing components according to different aluminum foil thicknesses or wire core diameters, achieving "one machine for multiple uses" and greatly expanding the equipment's process applicability. Furthermore, in the event of wear or blockage, it is not necessary to replace the entire device; only local modules need maintenance or replacement, significantly reducing spare parts inventory costs and equipment downtime.

[0021] This invention employs a dual radial and axial locking mechanism to ensure high stability and reliability in the pressing process. Axial tension is provided through the threaded connection of the locking mechanism, and the secondary pressing mechanism is radially tightened using a tightening screw, forming a reliable anti-loosening structure. This dual locking design effectively resists the continuous vibration generated during the operation of high-speed braiding equipment, preventing slight displacement of the pressing components, thus ensuring the symmetry of the aluminum foil covering and the consistency of the overlap width, guaranteeing long-term stable production.

[0022] This invention optimizes the convergence path of the aluminum foil and the wire core, ensuring the alignment and initial roundness of the wrapping from the outset. By setting up independent tapered aluminum foil channels and cable inlet tubes, this invention provides a precise and independent guiding path for the aluminum foil and the wire core before they converge. This design ensures that the two are in the optimal spatial relative position before entering the primary pressing mechanism, eliminating the problem of wrapping misalignment caused by initial misalignment, and laying a solid foundation for subsequent high-quality pressing.

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can clearly understand the technical solution and implementation of the present invention.

[0028] like Figures 1 to 3 As shown, this utility model provides a coaxial cable aluminum foil pressing device, including a fixed base 1 and an aluminum foil cable pressing component 2. In this embodiment, the fixed base 1 uses a standard braiding machine fixing nut, which has internally machined threaded connections and snap-fit ​​grooves. The aluminum foil cable pressing component 2 is connected to the fixed base 1 by rotation, forming a quickly detachable integrated structure.

[0029] The aluminum foil cable pressing component 2 comprises four main components connected in sequence: The converging guide mechanism 21 consists of a tapered aluminum foil channel 210, a limiting slot positioning plate 211, a snap-fit ​​part 212, and a cable guide tube 213. The tapered aluminum foil channel 210 is made of high-quality tool steel, and its cross-section is designed to taper, with an inlet width of 15mm, an outlet width of 8mm, and a contraction angle of 12°. This tapered structure allows the aluminum foil to smoothly and evenly wrap around the cable during passage.

[0030] The limiting slot positioning plate 211 is fixed above the front end of the tapered aluminum foil channel 210 by welding. Its slot width is 2mm, used to precisely limit the entry position of the aluminum foil strip. The cable guide tube 213 is vertically positioned above the tapered aluminum foil channel 210, with an inner diameter of 3mm, and is precisely aligned with the axis of the tapered aluminum foil channel 210. The snap-fit ​​part 212 is located on the lower side of the tapered aluminum foil channel 210, made of spring steel, and can form an elastic fit with the snap-fit ​​groove in the fixing base 1.

[0031] At the connection between the limiting slot positioning plate 211 and the primary pressing mechanism 22, a reinforcing support structure 214 is provided. The thickness of the support structure is 3mm, and it is arranged at a 45° angle, which effectively enhances the rigidity of the connection part.

[0032] The primary pressing mechanism 22 includes a multi-stage step positioning component 221, a pressing channel 222, and a first connecting structure 223. The multi-stage step positioning component 221 employs a three-stage step design, with a height difference of 2mm between each stage, enabling a stable fit with the contact surface within the limiting cavity 244 of the locking and fixing mechanism 24. The pressing channel 222 has an inner diameter of 8mm and a mirror-polished surface with a roughness Ra≤0.2μm, ensuring that the aluminum foil surface is not damaged during the pressing process. The first connecting structure 223 is located on the outer periphery of the pressing channel 222 and uses an M30×1.5 fine thread, enabling a reliable threaded connection with the secondary pressing mechanism 23.

[0033] The multi-stage step positioning component 221 can form a stable fit with the abutment surface within the limiting cavity 244 of the locking and fixing mechanism 24. The inner surface of the pressing channel 222 is mirror-polished to ensure that the aluminum foil surface is not damaged during the pressing process. The first connecting structure 223 is located on the outer periphery of the pressing channel 222 and can form a reliable threaded connection with the secondary pressing mechanism 23.

[0034] The secondary pressing mechanism 23 includes a secondary step positioning member 231, a tapered pressing cavity 232, and a second connecting structure 233. The outer diameter of the secondary step positioning member 231 is 28 mm, and it forms a sliding fit with the limiting cavity 244 of the locking and fixing mechanism 24.

[0035] The tapered pressing chamber 232 has an inlet diameter of 8mm, an outlet diameter of 6mm, and a contraction angle of 8°, enabling further fine pressing of the aluminum foil cable after the initial pressing. The second connecting structure 233 is machined at the inlet end of the tapered pressing chamber 232 and uses an M30×1.5 internal thread that matches the first connecting structure 223, forming a detachable connection with the primary pressing mechanism 22 through a threaded connection.

[0036] The locking and fixing mechanism 24 includes a card holder body 241, a third connecting structure 242, a tightening screw locking element 243, and a limiting cavity 244. The card holder body 241 adopts a split structure for easy installation and maintenance.

[0037] The third connecting structure 242 is located at the front end and uses an M40×2 thread specification, which can reliably connect with the threaded connection part of the fixed base 1. The inner diameter of the limiting cavity 244 is 30mm, and an axial abutment surface is machined inside, which can provide stable axial support for the multi-stage stepped positioning component 221.

[0038] Two locking screws 243 are provided, symmetrically distributed on the side wall of the card holder body 241. They are made of M4×0.7 fine thread screws, which can tighten the secondary step positioning part 231 by rotation, preventing it from rotating or displacing during operation.

[0039] To facilitate understanding of the above technical solutions of this utility model, the following detailed description of the above technical solutions of this utility model is provided through specific usage methods.

[0040] First, the first connecting structure 223 at the front end of the pressing channel 222 of the primary pressing mechanism 22 of the aluminum foil cable pressing component 2 is rotated and fixed to the second connecting structure 233 at the rear end of the secondary pressing mechanism 23, thereby connecting the primary pressing mechanism 22 and the secondary pressing mechanism 23 into a whole.

[0041] Next, the convergence guide mechanism 21 of the aluminum foil cable pressing component 2 is moved downward through the limiting cavity 244 of the locking and fixing mechanism 24 until the multi-stage step positioning component 221 of the primary pressing mechanism 22 contacts the abutment ring on the inner edge of the card holder body 241.

[0042] Then, the top screws 243 on both sides of the rotating locking and fixing mechanism 24 press the secondary step positioning member 231 inward, thereby fixing the components of the aluminum foil cable pressing component 2 together.

[0043] Finally, the third connecting structure 242 at the front end of the locking and fixing mechanism 24 is threadedly connected to the locking thread groove on the inner edge of the fixing base 1, i.e. the fixing nut of the braiding machine, and locked. At the same time, it is ensured that the snap-fit ​​part 212 on the lower side of the converging guide mechanism 21 is snapped into the snap-fit ​​block inside the fixing base 1, thus completing the installation of the entire device.

[0044] In actual use, the aluminum foil and cable are respectively conveyed by the braiding machine and enter the tapered aluminum foil channel 210 and cable inlet tube 213 of the converging guide mechanism 21 of the aluminum foil and cable pressing component 2. The cable enters the tapered aluminum foil channel 210 from the cable inlet tube 213. Since the channel has a tapered structure, the aluminum foil begins to wrap around the cable during this process and completes the initial pressing when it flows into the narrow section of the channel. Subsequently, the initially wrapped aluminum foil cable enters the tapered pressing chamber 232 of the secondary pressing mechanism 23 for secondary pressing and is then output to form a round and smooth aluminum foil shielding layer.
