Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of cable production, and more specifically, to a wire stranding machine for wire processing. Background Technology

[0002] In wire and cable production, stranding machines are key equipment for twisting single wires such as copper and aluminum wires into strands at a specific pitch. They improve the conductivity and mechanical strength of the wires, and their operating efficiency directly determines the overall production capacity of wire processing. As the demand for wires shifts towards smaller diameters and higher flexibility, the requirements for the automation level and process continuity of stranding machines are increasing. However, traditional wire stranding machines have significant shortcomings: the raw material feeding and finished product unloading processes are cumbersome, requiring extensive manual intervention, frequently interrupting production, and severely restricting efficiency. Traditional wire twisting machines are difficult to operate by a single person during feeding, and require precise alignment of the feed spool center; otherwise, uneven tension in the single wire can easily lead to wire breakage during twisting or uneven strand tension. After the finished product is wound up, unloading still relies on manual labor, requiring loosening bolts, removing protective components, and then moving the finished product reel to the storage area. In mass production, inconsistent manual operation can lead to issues such as misaligned loading and unloading, which can scratch the strands or reduce stranding accuracy, increasing the defect rate. Furthermore, high-intensity handling poses safety hazards to operators, including lumbar muscle strain and injuries from impacts. Therefore, developing wire stranding machines that simplify loading and unloading processes and reduce manual intervention has become an urgent need for the industry to improve efficiency and safety.

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] like Figures 1-3 As shown, a wire stranding machine for wire processing according to an embodiment of the present disclosure is illustrated, comprising: A base plate 1 and a support 2, wherein the support 2 is fixed on the base plate 1; Cable laying twisting assembly 4 is disposed on the stand 2 and the base plate 1; The upright plate 3 and the winding assembly 5 are provided on the upright plate 3. The upright plate 3 is fixed to one end of the surface of the base plate 1, and the winding assembly 5 is disposed on the upright plate 3. The cable laying and stranding assembly 4 includes a rotating disk 4-1, which is rotatably fitted into the support 2. The rotating disk 4-1 is electrically driven to rotate. Several mounting posts 4-2 are horizontally fixedly connected to the surface of the rotating disk 4-1. Several positioning sleeves 4-3 are inserted and connected to the surface of the rotating disk 4-1. The positioning sleeves 4-3 are rotatably fitted into one end of the mounting posts 4-2 and are fixedly connected to the surface of the rotating disk 4-1 by bolts. The positioning sleeve 4-3 has a defense hole 4-4 on its surface. The base plate 1 has a column 4-5 on its surface. A clustering disk 4-6 is rotatably connected to the upper end of the column 4-5. A long rod 4-7 is provided on one side of the column 4-5. A cable-forming cover 4-8 is provided at one end of the long rod 4-7. A central rod 4-9 is provided at the center of the side surface of the clustering disk 4-6. A sorting block 4-10 is provided at one end of the central rod 4-9. The outer surface of the sorting block 4-10 is a spherical smooth surface.

[0022] In some examples, in order to achieve stable release and precise twisting of multi-strand wires, while also taking into account the rapid replacement of wires and improving the efficiency of wire stranding, a cable release and stranding assembly 4 is designed. The rotating disk 4-1, which is mounted inside the stand 2 of this assembly, is driven by electricity (such as a motor with belt drive) to rotate around the axis of the stand 2, providing rotational power for wire stranding.

[0023] Several mounting posts 4-2, which are horizontally fixed on the surface of the rotating disk 4-1, are evenly distributed in a ring to provide mounting base points for the positioning sleeve 4-3. The positioning sleeve 4-3 is connected to one end of the mounting post 4-2 by a rotating sleeve and can rotate freely around the mounting post 4-2 to ensure that the positioning sleeve 4-3 can rotate with the wire when the wire is released, thereby reducing wire pulling damage.

[0024] The positioning sleeve 4-3 is fixed to the surface of the rotating disk 4-1 by bolts. Loosening the bolts can adjust the position of the positioning sleeve 4-3 on the rotating disk 4-1 to adapt to the wire laying requirements of different specifications. The anti-line hole 4-4 on the surface of the positioning sleeve 4-3 is adapted to the diameter of the wire and can guide and constrain the wire to prevent the wire from shifting during the laying process.

[0025] The bundling disc 4-6, which is mounted on the upper end of the column 4-5 on the surface of the base plate 1, can initially gather multiple strands of wire. The cable-forming cover 4-8 at one end of the long rod 4-7 on one side of the column 4-5 has a conical structure, which can further sort the gathered wire and ensure that the multiple strands of wire are evenly twisted. The center rod 4-9 at the center of the axis on the side surface of the bundling disc 4-6 is connected to the sorting block 4-10. The spherical smooth surface of the sorting block 4-10 can reduce the friction between the wire and the component, avoid wear on the surface of the wire, and at the same time help keep the wire centered and twisted.

[0026] During operation, multiple strands of wire pass through the anti-line holes 4-4 of different positioning sleeves 4-3, are gathered by the bundling plate 4-6, and combed by the cable forming cover 4-8 before entering the subsequent processing stage; the rotating plate 4-1 rotates, driving the positioning sleeves 4-3 to rotate synchronously, realizing the twisting of multiple strands of wire; when changing wire, the fixing bolts of the positioning sleeves 4-3 can be loosened to quickly remove the positioning sleeves 4-3 and replace the wire roll.

[0027] The rotational engagement of the mounting post 4-2 and the positioning sleeve 4-3 reduces the resistance of wire feeding. The bolt fixing design enables quick assembly and disassembly of the positioning sleeve 4-3. The guiding effect of the spherical sorting block 4-10 and the cable forming cover 4-8 improves the stranding accuracy. The cooperation of all components ensures stable wire feeding, uniform stranding, and convenient wire replacement.

[0028] like Figures 1-3As shown in the figure, the winding assembly 5 in this embodiment includes a rotating shaft 5-1, which is horizontally connected to the side surface of the upright plate 3 by electric drive. A winding reel 5-2 is fitted onto the rotating shaft 5-1. A side support frame 5-3 is provided on the surface of the base plate 1. The side support frame 5-3 is located on one side of the rotating shaft 5-1. A pair of telescopic cylinders 5-4 are horizontally connected to the side surface of the side support frame 5-3. A pressing sleeve 5-5 is provided at the output end of the telescopic cylinder 5-4. A base frame 5-6 is provided on the surface of the base plate 1. A second cylinder 5-7 is vertically installed at the top of the base frame 5-6. A bracket 5-8 is provided at the output end of the second cylinder 5-7. The bracket 5-8 is slidably fitted onto one bottom end of the winding reel 5-2. Both ends of the bracket 5-8 are provided with pulleys 5-9, which are in contact with the outer surface of the winding reel 5-2.

[0029] In some examples, in order to achieve tight winding of the stranded wire and convenient loading and unloading of the winding reel 5-2, and to ensure winding quality and processing continuity, a winding assembly 5 is designed. The rotating shaft 5-1 inside the side surface of the upright plate 3 of this assembly is driven by electricity (such as a servo motor directly connected) to rotate horizontally. The winding reel 5-2 is connected to the rotating shaft 5-1 in a set manner. The rotating shaft 5-1 drives the winding reel 5-2 to rotate synchronously, providing power for winding the wire.

[0030] The combination of the take-up reel 5-2 and the rotating shaft 5-1 facilitates the quick disassembly and reassembly of the take-up reel 5-2. After winding is completed, the take-up reel 5-2 can be directly removed from the rotating shaft 5-1 and replaced with an empty take-up reel 5-2.

[0031] The side support frame 5-3 on the surface of the base plate 1 is located on one side of the rotating shaft 5-1. A pair of telescopic cylinders 5-4 are symmetrically distributed and horizontally connected to its side surface. The output end of the telescopic cylinder 5-4 is fixedly connected to the clamping sleeve 5-5. The inner wall of the clamping sleeve 5-5 is adapted to the outer surface of the take-up reel 5-2. During winding, the telescopic cylinder 5-4 drives the clamping sleeve 5-5 to fit against the surface of the take-up reel 5-2, forming radial pressure on the wound wire to ensure that the wire is tightly wound on the take-up reel 5-2 and to avoid loosening.

[0032] The second cylinder 5-7 is vertically mounted on the top of the base frame 5-6 on the surface of the base plate 1. Its output end is fixedly connected to the bracket 5-8. The bracket 5-8 is fitted to one end of the bottom of the take-up reel 5-2 by a sliding sleeve. Its height can be adjusted according to the diameter of the take-up reel 5-2. The pulleys 5-9 at both ends of the bracket 5-8 are in contact with the outer surface of the take-up reel 5-2. This can reduce the friction between the bracket 5-8 and the take-up reel 5-2 and provide auxiliary support for the take-up reel 5-2 to prevent it from tilting due to the excessive weight of the wire.

[0033] During operation, the second cylinder 5-7 drives the bracket 5-8 to rise, causing the pulley 5-9 to fit against the bottom of the take-up reel 5-2, providing support for the take-up reel 5-2; the telescopic cylinder 5-4 drives the clamping sleeve 5-5 to fit against the side of the take-up reel 5-2, ensuring that the wire is tightly wound; the rotating shaft 5-1 drives the take-up reel 5-2 to rotate, realizing the winding of the wire; after winding is completed, the telescopic cylinder 5-4 drives the clamping sleeve 5-5 to retract, and the second cylinder 5-7 drives the bracket 5-8 to descend, so that the take-up reel 5-2 can be removed.

[0034] The radial pressure of the clamping sleeve 5-5 improves the tightness of winding, the support of the bracket 5-8 and pulley 5-9 enhances the stability of the winding reel 5-2, and the assembly design of the winding reel 5-2 and the rotating shaft 5-1 enables quick loading and unloading. All components work together to improve winding quality and operating efficiency.

[0035] For example, such as Figure 3 As shown, one end of the cable forming cover 4-8 has a flared opening structure, and the inner diameter of the cable forming cover 4-8 matches the diameter of the cable.

[0036] In some examples, the flared opening structure at one end of the cabling cover 4-8 can guide multiple strands of wire into the cabling cover 4-8 more smoothly, avoiding jamming or scraping when the wires converge. The flared opening expands the entry range of the wires, so even if the multiple strands of wires are slightly deviated during the twisting process, they can still be smoothly guided by the opening.

[0037] The inner diameter of the cable cover (4-8) matches the cable diameter, which can precisely constrain the wires after they are gathered, prevent uneven stranding due to looseness during stranding, ensure that the final cable has a consistent diameter and a tight structure, and improve the quality of wire stranding.

[0038] For example, such as Figure 2 As shown, the clamping sleeve 5-5 has an arc-shaped structure, and the inner surface of the clamping sleeve 5-5 is a smooth surface.

[0039] In some examples, the arc-shaped structure of the clamping sleeve 5-5 can fit more closely to the outer surface of the winding reel 5-2, so that the clamping force is evenly applied to the winding wire, avoiding excessive local pressure that could cause wire deformation, or insufficient pressure that could cause loose winding.

[0040] The smooth surface of the inner side of the clamping sleeve 5-5 reduces friction with the wire surface, preventing scratches on the wire insulation layer during winding, ensuring the wire's appearance and performance are intact, ensuring both the tightness of winding and protecting the wire's processing quality, thus improving the practicality and reliability of the winding assembly 5.

[0041] In practical use: The wire coil is installed on the positioning sleeve 4-3 of the cable unwinding assembly 4, and the positioning sleeve 4-3 is fixed in position with bolts. One end of the wire passes through the anti-line hole 4-4, is gathered by the bundling disc 4-6, combed by the cable forming cover 4-8, and the spherical sorting block 4-10 helps to center the wire. The electric drive rotates the rotating disc 4-1 around the stand 2, driving the positioning sleeve 4-3 to rotate synchronously, realizing the twisting of multiple strands of wire. The twisted wire is conveyed to the winding assembly 5. The second cylinder 5-7 drives the bracket 5-8 to rise, the pulley 5-9 fits against the bottom of the winding reel 5-2 to provide support, and the telescopic cylinder 5-4 pushes the arc-shaped pressing sleeve 5-5 to fit against the side of the winding reel 5-2 to ensure that the wire is tightly wound. The electric drive rotating shaft 5-1 drives the winding reel 5-2 to rotate and take in the wire. After winding is completed, the telescopic cylinder 5-4 drives the clamping sleeve 5-5 to retract, and the second cylinder 5-7 drives the bracket 5-8 to descend. The winding reel 5-2 is removed and replaced with a new one. The entire process of cable unwinding, stranding and winding is automated, reducing manual intervention.
