Abstract
Description
Technical Field
[0001] This utility model relates to the field of stranded wire processing technology, and specifically to a stranding device for preventing strand jumps. Background Technology
[0002] Stranded wire is a composite conductor formed by multiple pre-stretched conductors through verification or winding. Stranded wire has a larger total surface area, effectively reducing metal fatigue and stress, and improving current carrying capacity. Its structural characteristics often outperform solid conductors of the same cross-sectional area in terms of flexibility and conductivity. With the rapid development of industrial technology, the demand for wire is also increasing rapidly. Therefore, in wire production, major manufacturers typically use stranding equipment to replace traditional manual stranding, ensuring processing efficiency and stranding quality.
[0003] Currently available stranding equipment can strand wires. For example, Chinese utility model patent application CN202736594 U discloses an automatic stranding machine wire separating device, which includes: a horizontal moving module, a support, and at least two separating cylinders. The support is horizontally movable and mounted on the horizontal moving module. The separating cylinders are all fixed on the support and can extend and retract vertically. Each separating cylinder has a separating tooth at its lower end, and there is a gap between adjacent separating teeth. This utility model can effectively prevent the wire from becoming loose at the alternation position of stranded and straight sections, thereby ensuring the quality of the stranded wire.
[0004] However, this existing automatic stranding machine's wire separating device still has the following shortcomings: In this technical solution, a splitting cylinder drives splitting teeth to twist the wires. However, this method is generally only suitable for twisting two-strand wires. It is difficult to apply to three-strand or more wires that need to be twisted, and it is prone to uneven twisting and strand skipping due to uneven stress on each strand and skewed twisting angles. This is especially true for wires that require multi-layer stacking and twisting, which cannot be twisted at all. Furthermore, uneven twisting and strand skipping seriously affect the electrical performance and mechanical strength of the cable, reduce product quality and reliability, increase the difficulty and cost of subsequent processing, and become a major factor restricting the improvement of cable production quality.
[0005] In view of the above, the inventors propose the following technical solution. Summary of the Invention
[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a mobile phone holder for electric vehicles.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a stranding device for preventing strand jumps, comprising: a first wire distributor, wherein the first wire distributor has several rings of first threading holes for the wire strands to pass through, and a first eyelet for the wire strands to pass through is provided at the center of the first wire distributor; a second wire distributor, wherein the second wire distributor has several rings of second threading holes for the wire strands to pass through, and a second eyelet for bundling the wire strands is provided at the center of the second wire distributor; and a third stranding die, wherein a third eyelet for bundling the wire strands is provided at the center of the third stranding die.

[0010] Furthermore, in the above technical solution, the third stranding die includes a third positioning plate that can be slidably sleeved on the mounting and adjusting part, a third adjusting screw installed on one side of the third positioning plate for adjusting tightness, a third support frame set on the third positioning plate, an eyelet sleeve set on the third support frame, and a third eyelet set inside the eyelet sleeve.
[0011] Furthermore, in the above technical solution, the first threading hole includes a plurality of first inner ring threading holes arranged in a ring on the first disc body and a plurality of first outer ring threading holes arranged in a ring around the first inner ring threading holes, and the number of first outer ring threading holes is greater than the number of first inner ring threading holes; when the strand passes through the first inner ring threading hole and merges into the second eye mold, the second eye mold twists the strand.
[0012] Furthermore, in the above technical solution, the second threading hole on the second splitter is provided in at least one ring, and each ring is composed of multiple second threading holes. When the strands pass through the first outer ring threading hole and converge into the third eye mold, the third eye mold twists the strands together.
[0013] Furthermore, in the above technical solution, the first eye mold has a first through hole at its center for threading strands; the second eye mold has a second twisting hole for twisting strands; and the third eye mold has a third twisting hole for twisting strands.
[0014] Furthermore, in the above technical solution, the second eye mold and the third eye mold are both cylindrical structures, and the first eye mold, the second eye mold and the third eye mold are all made of ceramic material.
[0015] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: In this utility model, the strands are threaded in layers through the first and second dividing discs, and two stranding operations are performed through the second and third eyelets. This allows for stranding of three or more strands, effectively avoiding strand skipping and significantly improving the roundness of the stranded wire. It is suitable for widespread application in various stranding equipment. Furthermore, compared with existing structures, this utility model eliminates the traditional dividing teeth. By setting the first and second threading holes on the first and second dividing discs respectively for strand threading, the stranding speed can be controlled during the stranding process, effectively avoiding uneven force and angle distortion, ensuring a stable stranding process, and guaranteeing the quality of the stranded wire. Attached Figure Description
[0016] Figure 1 This is a three-dimensional structural diagram of the present invention.
[0017] Figure 2 This is a cross-sectional schematic diagram of the present invention. Detailed Implementation
[0018] The present invention will be further described below with reference to specific embodiments and accompanying drawings.
[0019] See Figures 1 to 2 As shown, a stranding device for preventing strand jumps in stranded wire includes: a first wire distributor 1, which has several rings of first threading holes 12 for strands 5 to pass through, and a first eyelet 11 for strands 5 to pass through is provided at the center of the first wire distributor 1; a second wire distributor 2, which has several rings of second threading holes 22 for strands 5 to pass through, and a second eyelet 21 for stranding strands 5 is provided at the center of the second wire distributor 2; and a third stranding die 3, which has a third eyelet 31 for stranding strands 5 at the center of the third stranding die; preferably, the first eyelet 11, the second eyelet 21 and the third eyelet 31 are arranged coaxially.
[0020] In this invention, the strands 5 are threaded in layers using the first dividing reel 1 and the second dividing reel 2, and then bundled twice using the second eyelet 21 and the third eyelet 31. This allows for the bundling of three or more strands, effectively preventing strand skipping and significantly improving the roundness of the stranded wire. It is suitable for widespread application in various stranding equipment. Furthermore, compared to existing structures, this invention eliminates the traditional dividing teeth. First threading holes 12 and second threading holes 22 are respectively provided on the first dividing reel 1 and the second dividing reel 2 for threading the strands 5. This allows for control of the bundling speed during the bundling process, effectively preventing uneven force and angle misalignment, ensuring a stable bundling process, and guaranteeing the quality of the stranded wire.
[0021] Preferably, the first wire splitter 1, the second wire splitter 2, and the third stranding die 3 are arranged at adjustable intervals on a mounting and adjusting part 4.
[0022] Since this utility model aims to achieve an adjustable arrangement of the first wire distributor 1, the second wire distributor 2, and the third stranding die 3 on the mounting adjustment part 4, it is necessary to adjust the interval between the first wire distributor 1 and the second wire distributor 2 to accommodate the stranding of different types of wires (different wires require different intervals when stranding). Specifically, the first wire distributor 1 includes a first positioning plate 101 slidably sleeved on the mounting adjustment part 4, a first adjusting screw 102 mounted on one side of the first positioning plate 101 for adjusting tightness, a first support frame 103 mounted on the first positioning plate 101, a first disc body 104 mounted on the first support frame 103, a first threading hole 12 opened on the first disc body 104 for the wire strand 5 to pass through, and a first eye die 11 located at the center of the first disc body 104 for the wire strand 5 to pass through. The first disc body 104 has a circular disc structure. Here, when the first adjusting screw 102 is tightened, it will cause the first positioning plate 101 to be clamped on the mounting adjustment part 4. The operator can loosen the first adjusting screw 102 to release the first positioning plate 101, and then slide it along the mounting adjustment part 4 for adjustment.
[0023] The second wire splitter 2 includes a second positioning plate 201 slidably sleeved on the mounting adjustment part 4, a second adjusting screw 202 mounted on one side of the second positioning plate 201 for adjusting tightness, a second support frame 203 mounted on the second positioning plate 201, a second disc body 204 mounted on the second support frame 203, and a second eyelet 21 located at the center of the second disc body 204 for allowing the wire strands 5 to pass through. The second disc body 204 has a circular disc structure. The third stranding die 3 includes a third positioning plate 301 slidably sleeved on the mounting adjustment part 4, a third adjusting screw 302 mounted on one side of the third positioning plate 301 for adjusting tightness, a third support frame 303 mounted on the third positioning plate 301, an eyelet sleeve 304 mounted on the third support frame 303, and a third eyelet 31 located inside the eyelet sleeve 304. Here, the sliding method of the second wire splitter 2 and the third stranding die 3 is roughly the same as that of the first wire splitter 1, and can be referred to the first wire splitter 1, without further explanation.
[0024] The first threading hole 12 includes a plurality of first inner ring threading holes 121 arranged in a ring on the first disc 104 and a plurality of first outer ring threading holes 122 arranged in a ring around the first inner ring threading holes 121, and the number of first outer ring threading holes 122 is greater than the number of first inner ring threading holes 121; when the strand 5 passes through the first inner ring threading holes 121 and merges into the second eyelet 21, the second eyelet 21 twists the strand 5. The second threading hole 22 on the second splitter disc 2 has at least one ring, each ring consisting of a plurality of second threading holes 22; when the strand 5 passes through the first outer ring threading holes 122 and merges into the third eyelet 31, the third eyelet 31 twists the strand 5. Wherein, combined with Figure 2 As shown, the wire strand 5 passing through the first inner ring wire hole 121 is first twisted through the second eyelet 21 on the second wire distributor 2; the wire strand 5 passing through the first outer ring wire hole 122 will continue to pass through the second wire hole 22 and be twisted through the third eyelet 31 for a second time to achieve double twisting. In addition, it can be understood that when triple twisting is required, it can be achieved by adding a wire distributor.
[0025] The first eye mold 11 has a first through hole 111 at its center for thread strand 5 to pass through; the second eye mold 21 has a second twisting hole 211 for twisting thread strand 5; and the third eye mold 31 has a third twisting hole 311 for twisting thread strand 5.
[0026] The second eye mold 21 and the third eye mold 31 are both cylindrical structures, and the first eye mold 11, the second eye mold 21 and the third eye mold 31 are all made of ceramic material.
[0027] In summary, this utility model employs layered threading of the strands 5 through the first and second dividing discs 1 and 2, and performs two stranding operations through the second eyelet 21 and the third eyelet 31. This allows for stranding of three or more strands, effectively preventing strand skipping and significantly improving the roundness of the stranded wire. It is suitable for widespread application in various stranding equipment. Furthermore, compared to existing structures, this utility model eliminates the traditional dividing teeth. By providing a first threading hole 12 and a second threading hole 22 on the first and second dividing discs 1 and 2 respectively for threading the strands 5, the stranding speed can be controlled during the stranding process, effectively preventing uneven force and angle distortion, ensuring a stable stranding process, and guaranteeing the quality of the stranded wire. Of course, the above description is merely a specific embodiment of this utility model and is not intended to limit its scope.
