Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable processing technology, and more specifically, to a wire stranding machine for cable processing. Background Technology
[0002] Proper cable processing can reduce material waste and processing time, thereby lowering production costs. At the same time, high-quality processing can reduce cable failure rates during use and improve system operating efficiency.
[0003] In cable processing, the cables are twisted into strands, making them more flexible, bendable, and less prone to breakage, thus suitable for various complex installation environments. This flexibility not only facilitates construction and installation but also improves the cable's durability and extends its service life.
[0004] In contrast to traditional stranding devices, the stranded cable is usually evenly distributed onto the take-up roller. This even distribution is often achieved using a moving structure and a straightening component. However, since the size of the undulating ring is fixed, it cannot accommodate cables of different thicknesses after stranding. If a large diameter ring is used directly, it will affect the uniformity of the winding. Furthermore, friction between the straightening component and the cable will cause some wear on the cable. Therefore, it is necessary to improve and optimize a stranding machine for cable processing. Utility Model Content

[0009] As a preferred technical solution of this utility model: the limiting structure includes a limiting rod fixedly connected to the front surface of the rear correction component, the surface of the lower limiting rod is threaded, the surface of the limiting rod is movably connected to the interior of the front correction component, and a nut is threadedly connected to the surface of the thread.
[0010] As a preferred technical solution of this utility model: a U-shaped frame is fixedly connected to the upper surface of the base plate, a carrier shaft is rotatably connected inside the U-shaped frame, a first bevel gear is fixedly connected to one end of the carrier shaft, a second motor is fixedly connected to the upper surface of the base plate, the output shaft of the second motor is rotatably connected to the inside of the U-shaped frame, a second bevel gear is fixedly sleeved on the output shaft of the second motor, and the second bevel gear and the first bevel gear mesh with each other.
[0011] As a preferred technical solution of this utility model: a third motor is fixedly installed on the upper surface of the left fixed frame, a gear is fixedly connected to the output shaft of the third motor, and a gear ring is fixedly sleeved on the middle surface of the rotating cylinder, and the gear ring and the gear mesh with each other.
[0012] As a preferred technical solution of this utility model: a fixed support plate is fixedly connected to the upper surface of the base plate, a take-up roller is rotatably connected inside the fixed support plate, a fourth motor is fixedly installed on the upper surface of the front fixed support plate, and the output shaft of the fourth motor is detachably installed to the front end of the take-up roller.
[0013] As a preferred technical solution of this utility model: a retaining ring is fixedly connected to the left side surface of the rotating cylinder, and the right side surface of the retaining ring is in contact with the left side surface of the twisted wire.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model uses a rotating knob to drive the bidirectional threaded rod to rotate inside the T-shaped frame. Since the spiral directions of the bidirectional threaded rod are opposite, the distance between the front and rear straightening parts can be adjusted, allowing the straightening parts to adapt to cables of different thicknesses. The rounded corner design prevents excessive wear on the cables. As the straightening parts move back and forth with the moving structure, the cables come into contact with the inner side of the straightening parts. At this time, the threaded connection between the nut and the threaded part prevents the straightening parts from rotating in the opposite direction due to the compression of the cables.
[0018] 2. This utility model achieves the replacement of the twisted wire component by pushing and moving it out from the right end of the rotating cylinder. When the left surface of the twisted wire component is aligned with the right surface of the retaining ring, that is, when the twisted wire component can no longer be pushed, the rotating shaft is rotated inside the rotating cylinder by rotating the fixing bar, preventing it from moving out of the rotating cylinder. When the movable locking pin is rotated to align with the limiting hole groove, it is pushed to the left, thereby fixing the position of the twisted wire component inside the twisted wire component. The movable locking pin is located inside the twisted wire component and perpendicular to the rotation direction of the twisted wire component, thus making this device highly practical. It can replace cables with different numbers of strands for twisting and can also be used to repair the twisted wire component. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] like Figures 1 to 8 As shown, this utility model provides a wire stranding machine for cable processing, including a base plate 1. A movable structure is provided on the upper surface of the base plate 1. A T-shaped frame 2 is movably connected inside the movable structure. A straightening component 3 is movably connected inside the T-shaped frame 2. A bidirectional threaded rod 4 is rotatably connected inside the T-shaped frame 2. The surface of the bidirectional threaded rod 4 is threadedly connected to the inside of the straightening component 3. A knob 5 is fixedly connected to the front surface of the bidirectional threaded rod 4. Rounded corners 6 are provided on both the left and right sides of the straightening component 3. A limit structure is provided on the front surface of the rear straightening component 3.
[0030] The operator places the cable reel that needs to be twisted onto the surface of the carrier shaft 20, and pulls it through the inside of the twisting component 9 and the straightening component 3, finally winding it up from the surface of the take-up roller 28. Then, the operator starts each drive device. Before twisting the cable, the operator turns the knob 5. The rotation of the knob 5 causes the bidirectional threaded rod 4 to rotate inside the T-shaped frame 2, thereby adjusting the distance between the straightening component 3, which is threadedly connected to the bidirectional threaded rod 4. By rotating the nut 18 and stopping the rotation of the knob 5, the position of the straightening component 3 is positioned. At this time, by activating the moving structure, the twisted cable can be evenly distributed on the surface of the take-up roller 28.
[0031] Among them, a fixed frame 7 is fixedly connected to the upper surface of the base plate 1, a rotating cylinder 8 is rotatably connected inside the fixed frame 7, a twisted wire component 9 is movably connected inside the knob 5, a rotating shaft 10 is rotatably connected inside the right end of the rotating cylinder 8, a fixed strip 11 is fixedly connected to the right end of the rotating shaft 10, a movable locking post 12 is movably connected inside the fixed strip 11, and the movable locking post 12 is movably connected to the inside of the twisted wire component 9.
[0032] The operator pushes the twisted wire 9 into the interior of the rotating cylinder 8 from the right end. Simultaneously, due to the limiting effect of the retaining ring 30, the two ends of the twisted wire 9 are aligned with the two ends of the rotating cylinder 8. At the same time, the fixing bar 11 is rotated, causing the rotating shaft 10 to rotate inside the rotating cylinder 8. This aligns the movable locking pin 12 with the position of the limiting hole groove 32, and pushes the movable locking pin 12 to the left, allowing it to enter the interior of the twisted wire 9. The presence of three sets of rotating shafts 10 ensures that the position of the twisted wire 9 is fixed.
[0033] The movable structure includes a limiting groove 13 fixedly connected to the upper surface of the base plate 1. The interior of the limiting groove 13 is movably connected to the lower part of the T-shaped frame 2. A threaded rod 14 is rotatably connected inside the limiting groove 13. The surface of the threaded rod 14 is threadedly connected to the interior of the T-shaped frame 2. A first motor 15 is fixedly installed on the upper surface of the base plate 1. The output shaft of the first motor 15 is fixedly connected to the front end of the threaded rod 14.
[0034] The rotation of the output shaft of the first motor 15 drives the rotation of the limiting groove 13, thereby causing the T-shaped frame 2 to move back and forth inside the limiting groove 13, so that the twisted cable is evenly distributed on the surface of the take-up roller 28.
[0035] The limiting structure includes a limiting rod 16 fixedly connected to the front surface of the rear correction member 3. The surface of the lower limiting rod 16 is provided with a thread 17. The surface of the limiting rod 16 is movably connected to the interior of the front correction member 3. A nut 18 is threadedly connected to the surface of the thread 17.
[0036] By rotating the nut 18, the distance between the front and rear alignment members 3 is limited due to the fit between the nut 18 and the thread 17. This device avoids the phenomenon that the alignment member 3 drives the rotation of the bidirectional threaded rod 4 due to the cable contacting the inside of the alignment member 3, which would cause the alignment member 3 to be unstable in its positioning.
[0037] The upper surface of the base plate 1 is fixedly connected to a U-shaped frame 19, and a carrier shaft 20 is rotatably connected inside the U-shaped frame 19. One end of the carrier shaft 20 is fixedly connected to a first bevel gear 21. The upper surface of the base plate 1 is fixedly connected to a second motor 22. The output shaft of the second motor 22 is rotatably connected to the inside of the U-shaped frame 19. The output shaft of the second motor 22 is fixedly sleeved with a second bevel gear 23. The second bevel gear 23 and the first bevel gear 21 mesh with each other.
[0038] The rotation of the output shaft of the second motor 22 drives the rotation of the second bevel gear 23. Since the second bevel gear 23 and the first bevel gear 21 are divided into three groups, the carrier shaft 20 is driven to rotate inside the U-shaped frame 19. As a result, the cable rolls installed on the surface of the carrier shaft 20 enter the twisted wire part 9 from the right side of the U-shaped frame 19. The number of cable rolls can be placed according to actual needs.
[0039] The upper surface of the left fixed frame 7 is fixedly mounted with a third motor 24, the output shaft of the third motor 24 is fixedly connected with a gear 25, and the middle surface of the rotating cylinder 8 is fixedly sleeved with a gear ring 26, which meshes with the gear 25.
[0040] By starting the third motor 24, the rotation of the output shaft of the third motor 24 drives the rotation of the gear ring 26, which in turn drives the rotating cylinder 8 to rotate inside the fixed frame 7. However, since the twisted wire part 9 is located inside the rotating cylinder 8 and can be disassembled and installed, the cable can be twisted.
[0041] Among them, a fixed support plate 27 is fixedly connected to the upper surface of the base plate 1, and a take-up roller 28 is rotatably connected inside the fixed support plate 27. A fourth motor 29 is fixedly installed on the upper surface of the front fixed support plate 27, and the output shaft of the fourth motor 29 is detachably installed to the front end of the take-up roller 28.
[0042] The fixed support plate 27 provides support to the take-up roller 28 and the fourth motor 29. The rotation of the output shaft of the fourth motor 29 drives the rotation of the take-up roller 28. Since the take-up roller 28 and the output shaft of the fourth motor 29 are detachable, the take-up roller 28 can be replaced from above the fixed support plate 27.
[0043] A retaining ring 30 is fixedly connected to the left side surface of the rotating cylinder 8, and the right side surface of the retaining ring 30 is in contact with the left side surface of the twisted wire 9.
[0044] The design of the retaining ring 30 limits the installation of the twisted wire 9, thereby ensuring that the twisted wire 9 can be smoothly installed inside the rotating cylinder 8.
[0045] Among them, the lower surface of the base plate 1 is fixedly connected with support legs 31, and the support legs 31 are located at the four corners of the lower surface of the base plate 1.
[0046] The support leg 31 provides support to the base plate 1, thereby enabling the wire twisting machine to be installed at the site where wire twisting is required.
[0047] Among them, the right end of the twisted wire component 9 is provided with a limiting hole groove 32, and the shape of the limiting hole groove 32 matches the left end of the movable locking post 12.
[0048] The shape of the limiting hole groove 32 matches the shape of the movable locking post 12, so that when the wire twisting part 9 rotates, the movable locking post 12 rotates with the wire twisting part 9, reducing unnecessary wear on the surface of the movable locking post 12.
[0049] Working principle and usage process of this utility model:
[0050] The operator places the cable reel that needs to be twisted onto the surface of the carrier shaft 20, and pulls it through the inside of the twisting component 9 and the straightening component 3, finally winding it up from the surface of the take-up roller 28. Then, the operator starts each drive device. Before twisting the cable, the operator turns the knob 5. The rotation of the knob 5 causes the bidirectional threaded rod 4 to rotate inside the T-shaped frame 2, thereby adjusting the distance between the straightening component 3, which is threadedly connected to the bidirectional threaded rod 4. By rotating the nut 18 and stopping the rotation of the knob 5, the position of the straightening component 3 is positioned. At this time, by activating the moving structure, the twisted cable can be evenly distributed on the surface of the take-up roller 28.
[0051] The operator pushes the twisted wire 9 into the interior of the rotating cylinder 8 from the right end. Simultaneously, due to the limiting effect of the retaining ring 30, the two ends of the twisted wire 9 are aligned with the two ends of the rotating cylinder 8. At the same time, the fixing bar 11 is rotated, causing the rotating shaft 10 to rotate inside the rotating cylinder 8. This aligns the movable locking pin 12 with the position of the limiting hole groove 32, and pushes the movable locking pin 12 to the left, allowing it to enter the interior of the twisted wire 9. The presence of three sets of rotating shafts 10 ensures that the position of the twisted wire 9 is fixed.
[0052] The rotation of the output shaft of the first motor 15 drives the rotation of the limiting groove 13, thereby causing the T-shaped frame 2 to move back and forth inside the limiting groove 13, so that the twisted cable is evenly distributed on the surface of the take-up roller 28.
[0053] By rotating the nut 18, the distance between the front and rear alignment members 3 is limited due to the fit between the nut 18 and the thread 17. This device avoids the phenomenon that the alignment member 3 drives the rotation of the bidirectional threaded rod 4 due to the cable contacting the inside of the alignment member 3, which would cause the alignment member 3 to be unstable in its positioning.
[0054] The rotation of the output shaft of the second motor 22 drives the rotation of the second bevel gear 23. Since the second bevel gear 23 and the first bevel gear 21 are divided into three groups, the carrier shaft 20 is driven to rotate inside the U-shaped frame 19. As a result, the cable rolls installed on the surface of the carrier shaft 20 enter the twisted wire part 9 from the right side of the U-shaped frame 19. The number of cable rolls can be placed according to actual needs.
[0055] By starting the third motor 24, the rotation of the output shaft of the third motor 24 drives the rotation of the gear ring 26, which in turn drives the rotating cylinder 8 to rotate inside the fixed frame 7. However, since the twisted wire part 9 is located inside the rotating cylinder 8 and can be disassembled and installed, the cable can be twisted.
[0056] The fixed support plate 27 provides support to the take-up roller 28 and the fourth motor 29. The rotation of the output shaft of the fourth motor 29 drives the rotation of the take-up roller 28. Since the take-up roller 28 and the output shaft of the fourth motor 29 are detachable, the take-up roller 28 can be replaced from above the fixed support plate 27.
[0057] The design of the retaining ring 30 limits the installation of the twisted wire 9, thereby ensuring that the twisted wire 9 can be smoothly installed inside the rotating cylinder 8.
[0058] The support leg 31 provides support to the base plate 1, thereby enabling the wire twisting machine to be installed at the site where wire twisting is required.
[0059] The shape of the limiting hole groove 32 matches the shape of the movable locking post 12, so that when the wire twisting part 9 rotates, the movable locking post 12 rotates with the wire twisting part 9, reducing unnecessary wear on the surface of the movable locking post 12.
[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
