Abstract

This invention relates to the field of stranding technology and provides a high-speed stranding machine for multi-strand alloy wires, including a main body assembly and a rotating assembly. The rotating assembly includes a frame installed inside the main body assembly, and electric turntables are installed on both sides of the frame. A first wire tube is connected inside one of the first wire tubes, and a second wire tube is connected inside the other first wire tube. This device solves the problem that existing stranding bows are curved and the wire passage is located on the inner wall, making it inconvenient for workers to thread the wire bundle. This device replaces the traditional wire passage groove with an open U-shaped limiting component, combined with a wire clamping mechanism that slides along the sliding groove of the stranding bow body. After the wire bundle is positioned, it slides through the U-shaped limiting component with the wire clamping mechanism. This solves the problem of limited operation when the stranding bow is far away and avoids blind spots in the wire passage when close, reducing the difficulty of threading and improving the threading efficiency.

Description

Technical Field

[0001] This invention relates to the field of stranding technology, and more specifically, to a high-speed stranding machine for multi-strand alloy wires. Background Technology

[0002] High-speed stranding machines for multi-strand alloy wires are one of the core pieces of equipment in the production of wires, cables, and electronic wires. Through a high-speed rotating stranding mechanism, multiple single wires can be stranded into a stable wire bundle according to a specific pitch and direction. They feature high stranding speed, high precision, and high degree of automation, and are suitable for diverse production needs ranging from fine-gauge electronic wires to medium- and thick-gauge power cables. They are key equipment for improving the quality and efficiency of wire production.

[0003] Currently, when using existing high-speed stranding machines, workers first need to complete the initial threading preparation. After the multi-strand wire bundle has been fed from the reel and preliminarily shaped by the die, it is passed through the wire passage on the stranding bow. Then, the wire bundle is guided through the traction wheel and the wire guide wheel in sequence. Finally, the end of the wire bundle is fixed on the take-up device. After the threading is completed, the stranding bow begins to rotate at high speed. With the continuous traction of the traction wheel and the cooperation of the wire guide wheel, the multi-strand monofilaments are stably stranded into one. At the same time, the take-up device operates synchronously, evenly winding the stranded wire bundle onto the take-up reel, thus completing the entire stranding process of the wire bundle.

[0004] However, since the bow is curved and oriented towards the axis, and the wire passage is located on the inner wall of the bow, if the wire passage is oriented towards the worker for easy positioning, the distance between the bow and the worker will be too far, restricting the worker's hand operation and making it difficult to accurately control the end of the wire harness to prevent it from scattering. If the bow is moved closer to the worker to shorten the operating distance, the wire passage will be in a blind spot due to the structure of the bow, making it difficult for the worker to observe the wire harness threading and thus making it difficult to complete the threading operation smoothly, thereby reducing the efficiency of the threading process. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a high-speed stranding machine for multi-strand alloy wires.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-speed stranding machine for multi-strand alloy wires, comprising a main body assembly.

[0007] A rotating assembly includes a frame installed inside a main body assembly. Electric turntables are installed on both sides of the frame. A first conduit is connected through the interior of one of the electric turntables, and a second conduit is connected through the interior of the other electric turntable. Conical discs are connected to the outer walls of both the first and second conduits.

[0008] A drawbridge assembly includes a drawbridge body connected to the outer walls of two cone discs. A sliding groove is provided on the side wall of the drawbridge body, and both ends of the sliding groove extend to the outer wall of the corresponding cone disc. A wire clamping mechanism is slidably connected in the sliding groove. Multiple U-shaped limiting members are equidistantly connected to the inner side wall of the drawbridge body, and the sliding groove is located at the center of the opening of the U-shaped limiting member.

[0009] The take-up assembly is used to synchronously wind up the stranded alloy wire.

[0010] The present invention is further configured such that: the main component includes a housing, a support rod connected to one side of the housing, a coil and a mold sleeved and connected to the outer wall of the support rod, the coil and the mold, as well as the first and second conduits, are all coaxially arranged, and the rotating component is installed inside the housing.

[0011] The invention is further configured such that: the outer walls of both conical discs are provided with wire grooves, both ends of the bow body are installed inside the wire grooves, and a placement space is provided between the bow body and the inner bottom wall of the corresponding wire groove.

[0012] The present invention is further configured such that: the hoop mechanism includes a slide block slidably connected inside the slide groove, a connecting frame is connected to the bottom of the slide block, a first arc plate is connected to the bottom of the connecting frame, and a second arc plate is rotatably mounted inside the first arc plate.

[0013] The present invention is further configured such that: the opening of the first arc plate is oriented toward the take-up assembly, and one end of the second arc plate is provided with a constriction.

[0014] The present invention is further configured such that: one end of the outer side wall of the first arc plate is rotatably connected to an arc plate, and a pressure roller is installed on the inner wall of the arc plate.

[0015] The invention is further configured such that: the pressure roller is positioned between the constriction of the second arc plate and the first arc plate, and the bottom of the arc plate is provided with an opening.

[0016] The present invention is further configured such that: the outer walls of the first conduit and the second conduit are provided with through holes, and each through hole is rotatably connected to a guide wheel, the outer wall of the guide wheel being arranged opposite to the central axis of the conical disk.

[0017] The present invention is further configured such that: the take-up assembly includes two circular plates, which correspond to two conical discs; one of the circular plates is rotatably connected to the outer wall of the first cable tube via a bearing, and the other circular plate is rotatably connected to the outer wall of the second cable tube via a bearing; a connecting rod is connected between the two circular plates; a steering wheel set and two traction wheels are provided on the side of one of the circular plates away from the corresponding conical disc; and the two traction wheels are rotatably connected to the side wall of the corresponding circular plate.

[0018] The present invention is further configured such that: a guide rail is installed between the two circular plates, a transfer module is slidably connected on the guide rail, a take-up reel assembly is installed on one side of the transfer module, a take-up reel rotates between the two circular plates, and the take-up reel assembly is configured to cooperate with the take-up reel.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] (1) By improving the traditional wire passage groove to an open U-shaped limiting piece and matching it with a wire clamping mechanism that can slide along the groove of the bow body, the wire harness is positioned in the wire clamping mechanism. By sliding the wire clamping mechanism, the wire harness can be driven to pass through the U-shaped limiting piece in sequence. This solves the problem of limited hand operation when the bow body is far away, and avoids the visual blind spot where the wire passage is blocked when the bow body is close. This reduces the difficulty of threading and improves the efficiency of threading the wire harness on the bow assembly.

[0021] (2) By rotating the second arc plate and the first arc plate to form a closed tube, the wire bundle is prevented from falling from below during the wire threading process, thus ensuring the stability of the wire bundle threading. The wire bundle is positioned by using the conical constriction on the second arc plate. That is, after the wire bundle is threaded into the first arc plate, the second arc plate is rotated to move the constriction to the bottom of the wire bundle. The constriction firmly confines the wire bundle inside the first arc plate through the squeezing action, thus avoiding the wire bundle from shifting or loosening during the sliding process. At the same time, the conical constriction can gather the dispersed ends of the wire bundle, further improving the stability of the wire bundle threading and facilitating subsequent stranding operations.

[0022] (3) After the wire harness is threaded onto the bow assembly, it needs to be wound onto the traction wheel and steering wheel. Therefore, the worker rotates the second arc plate so that the opening directions of the first arc plate and the second arc plate are aligned, and the wire harness can quickly detach from the opening.

[0023] (4) By setting an arc plate and pressure roller structure on the outer side wall of the first arc plate, the wire harness is positioned and gathered by the first arc plate and the second arc plate. The pressure roller is moved by the arc plate, so that the tape is wrapped around the wire harness to realize the end wire harness. This not only prevents the end of the wire harness from loosening, but also prevents the tape from falling between the first arc plate and the second arc plate by placing the tape at the constriction position of the first arc plate.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0042] Please see Figures 1-11 The present invention provides the following technical solutions:

[0043] Example 1, see Figure 1 and Figure 2 A high-speed stranding machine for multi-strand alloy wire includes a main component 1. The main component 1 includes a housing 11, a support rod 12 connected to one side of the housing 11, a wire reel 13 sleeved and connected to the outer wall of the support rod 12, and a mold 14. The wire reel 13 and the mold 14 are coaxially arranged. When the alloy wire needs to be stranded, the operator first passes the multi-strand alloy wire through multiple through holes on the wire reel 13, and then strands the alloy wire together and passes it through the mold 14. The stranded alloy wire bundle is then inserted into the housing 11 for stranding.

[0044] See Figures 1-4 The rotating assembly 2 is installed inside the housing 11. The rotating assembly 2 is equipped with a twisting assembly 3. The twisting assembly 3 is used to support the stranded alloy wire bundle. That is, the multi-strand alloy wire bundle that extends into the housing 11 passes through the twisting assembly 3. The rotating assembly 2 is used to drive the stranded alloy wire bundle to swing, so that the multi-strand alloy wire bundle achieves the purpose of twisting by swinging.

[0045] See Figure 11 In actual production, the drawbridge assembly 3 is usually set up in two sets, and one set is used at a time. The two sets of drawbridge assemblies 3 have the same structure. In actual production, the workers will arrange the two sets of drawbridge assemblies 3 symmetrically and use one set at a time to ensure that the dynamic balance is optimized through mechanical structure when the drawbridge assembly 3 is running at high speed.

[0046] See Figure 3 and Figure 4 The rotating assembly 2 includes a frame 21 installed inside the main assembly 1. Electric turntables 22 are installed on both sides of the frame 21. A first conduit 23 is connected through the interior of one electric turntable 22, and a second conduit 25 is connected through the interior of the other electric turntable 22. The coil 13, the mold 14, the first conduit 23 and the second conduit 25 are all coaxially arranged. Through holes are opened on the outer walls of the first conduit 23 and the second conduit 25. A guide wheel 26 is rotatably connected inside each through hole. The outer wall of the guide wheel 26 is opposite to the central axis of the conical disc 24. The outer walls of the first conduit 23 and the second conduit 25 are connected to the conical disc 24. The first conduit 23 and the second conduit 25 are driven to rotate by the corresponding electric turntables 22. The two conical discs 24 are used to install the bow assembly 3, and a take-up assembly 4 is arranged between the two conical discs 24.

[0047] After the multi-strand alloy wire bundle enters the interior of the housing 11, it first passes through the second wire tube 25, and then turns through the corresponding guide wheel 26. The outer walls of the two conical discs 24 are provided with wire grooves 27. Both ends of the bow assembly 3 are installed inside the wire grooves 27, and there is a placement space between the bow assembly 3 and the inner bottom wall of the corresponding wire groove 27. After the alloy wire bundle is turned by the corresponding guide wheel 26, it passes through the interior of the corresponding wire groove 27 and the bow assembly 3 in sequence. Then, it turns again through the guide wheel 26 in the first wire tube 23 to the inner center position of the first wire tube 23. After that, it is picked up and wound up by the take-up assembly 4.

[0048] When the stranding begins, the two electric turntables 22 drive the first wire tube 23 and the second wire tube 25 to rotate, causing the two conical discs 24 and the stranding assembly 3 to rotate synchronously. During this process, the multi-strand alloy wire bundle completes the stranding by swinging. At the same time, the take-up assembly 4 continuously takes up the wire, thereby realizing continuous stranding operation.

[0049] See Figure 5 and Figure 6 The specific structure of the take-up assembly 4 is as follows:

[0050] The take-up assembly 4 includes two circular plates 41, which correspond to two conical discs 24. One circular plate 41 is rotatably connected to the outer wall of the first cable tube 23 via a bearing, and the other circular plate 41 is rotatably connected to the outer wall of the second cable tube 25 via a bearing. A connecting rod 42 connects the two circular plates 41. A steering wheel assembly 44 and two traction wheels 43 are provided on the side of one circular plate 41 away from the corresponding conical disc 24. The two traction wheels 43 are rotatably connected to the side wall of the corresponding circular plate 41. The steering wheel assembly 44 consists of a first steering wheel and a second steering wheel. The first steering wheel is at the same height as the axis of the first cable tube 23 and the bottom of one of the traction wheels 43, while the second steering wheel is at the same height as the top of the other traction wheel 43.

[0051] During threading, the alloy wire bundle that turns to the center of the first conduit 23 first contacts the first steering wheel and turns to the outer wall of the lower traction wheel 43. Then the alloy wire bundle is repeatedly wound on the outer walls of the two traction wheels 43, and finally exits through the upper traction wheel 43 and is turned by the second steering wheel.

[0052] See Figure 5 and Figure 6A guide rail 48 is installed between two circular plates 41. A transfer module 46 is slidably connected to the guide rail 48. A take-up reel group 47 is installed on one side of the transfer module 46. A take-up reel 45 rotates between the two circular plates 41. The take-up reel group 47 is configured to cooperate with the take-up reel 45. The take-up reel group 47 consists of a first take-up reel and a second take-up reel. After the alloy wire bundle is turned out from the second guide wheel, it is picked up by the first take-up reel and turned onto the take-up reel 45 with the assistance of the second take-up reel. The take-up reel 45 is used to take up the twisted alloy wire bundle. During the twisting process, the take-up reel 45 is synchronously driven to rotate by a drive motor, so that the take-up reel 45 synchronously takes up the wire bundle. At the same time, the transfer module 46 moves on the guide rail 48, thereby driving the take-up reel group 47 to move, so that the wire bundle moves outside the take-up reel 45, and thus the wire bundle can be neatly wound on the outer wall of the take-up reel 45.

[0053] In the second embodiment, when using the existing high-speed stranding machine, the operator first needs to complete the preliminary threading preparation. After the multi-strand wire bundle is unloaded by the wire reel 13 and preliminarily shaped by the mold 14, it is threaded into the housing 11 through the second wire tube 25. Then, it passes through multiple wire passages on the stranding assembly 3. Subsequently, the wire bundle is guided through the traction wheel 43, the steering wheel group 44 and the take-up wheel group 47 in sequence, and finally the end of the wire bundle is fixed on the take-up wheel 45.

[0054] Because the bow is curved and oriented towards the axis, and the wire passage is located on the inner wall of the bow, if the wire passage is oriented towards the worker for easy positioning, the distance between the bow and the worker will be too far, restricting the worker's hand operation and making it difficult to accurately control the end of the wire harness to prevent it from scattering. If the bow is moved closer to the worker to shorten the operating distance, the wire passage will be in a blind spot due to the structure of the bow, making it difficult for the worker to observe the wire harness threading and thus making it difficult to complete the threading operation smoothly, thereby reducing the efficiency of the threading process.

[0055] Therefore, further improvements were made to the drawbar assembly 3.

[0056] See Figures 3-8The bow assembly 3 includes a bow body 31 connected to the outer walls of two conical discs 24. The ends of the bow body 31 are placed inside the corresponding wire grooves 27. A sliding groove 32 is provided on the side wall of the bow body 31, and both ends of the sliding groove 32 extend to the outer wall of the corresponding conical discs 24. A wire clamping mechanism 34 is slidably connected inside the sliding groove 32. Multiple U-shaped limiting members 33 are equidistantly connected to the inner side wall of the bow body 31. The sliding groove 32 is located at the middle of the opening of the U-shaped limiting member 33. By setting the existing wire passage groove as a U-shaped limiting member 33, the U-shaped limiting member 33 is in an open state. In the initial state, the clamping mechanism 34 is positioned on the outer wall of the cone 24 corresponding to the second conduit 25. At this time, the operator can pass the wire harness through the clamping mechanism 34 and use the clamping mechanism 34 to clamp the alloy wire harness. Then, the operator slides the clamping mechanism 34, causing the clamping mechanism 34 to pass through the U-shaped limiter 33 and reach the outer wall position of another cone 24, thereby achieving the purpose of quickly threading the wire on the bow body 31. This eliminates the need for the operator to alternately pinch the wire with both hands to pass through multiple wire passages, improving the threading efficiency of the wire harness on the bow body 31.

[0057] Furthermore, since the wire clamping mechanism 34 remains on the cone plate 24 before and after wire threading, the wire clamping mechanism 34 will not affect the operation of the bow body 31 when the bow assembly 3 rotates.

[0058] See Figure 9 and Figure 10 The wire clamping mechanism 34 includes a slide block 341 slidably connected inside the slide groove 32. A connecting frame 342 is connected to the bottom of the slide block 341, and a first arc plate 343 is connected to the bottom of the connecting frame 342. A second arc plate 344 rotates inside the first arc plate 343. When the wire harness passes through the second conduit 25 and is turned by the corresponding guide wheel 26, the wire harness reaches the wire groove 27 on the outer wall of the corresponding cone disc 24. At this time, the end of the wire harness passes through the interior of the first arc plate 343. The operator rotates the second arc plate 344 to below the first arc plate 343. At this time, the first arc plate 343 and the second arc plate 344 cooperate to form a closed tube, such as... Figure 9 As shown, the wire harness will not fall from below the first arc plate 343.

[0059] See Figure 9 and Figure 10 The opening of the first arc plate 343 faces the take-up assembly 4. One end of the second arc plate 344 is provided with a constriction, which is tapered. When the wire harness passes through the inside of the first arc plate 343, the operator pulls the second arc plate 344 to rotate inside the first arc plate 343, causing the constriction of the second arc plate 344 to move below the wire harness. At this time, the wire harness is squeezed inside the first arc plate 343 by the constriction.

[0060] Specifically, by improving the traditional wire passage groove to an open U-shaped limiting member 33, and matching it with a wire clamping mechanism 34 that can slide along the groove 32 of the bow body 31, the wire harness is positioned in the wire clamping mechanism 34. By sliding the wire clamping mechanism 34, the wire harness can be driven to pass through the U-shaped limiting member 33 in sequence. This solves the problem of limited hand operation when the bow body 31 is far away, and avoids the visual blind spot where the wire passage is blocked when the bow body 31 is close. This reduces the difficulty of threading and improves the efficiency of threading the wire harness on the bow assembly 3.

[0061] By rotating the first arc plate 343 and the second arc plate 344 to form a closed tube, the wire harness is prevented from falling from below during the threading process, ensuring the stability of the wire harness threading. The wire harness is positioned by using the conical constriction on the second arc plate 344. That is, after the wire harness is threaded into the first arc plate 343, the second arc plate 344 is rotated to move the constriction to the bottom of the wire harness. The constriction firmly confines the wire harness inside the first arc plate 343 through the squeezing action, avoiding the wire harness from shifting or loosening during the sliding process. At the same time, the conical constriction can gather the scattered ends of the wire harness, further improving the stability of the wire harness threading and facilitating subsequent stranding operations.

[0062] In addition, after the wire harness is threaded onto the bow assembly 3, it needs to be wound onto the traction wheel 43 and the steering wheel assembly 44. Therefore, the operator rotates the second arc plate 344 to make the opening directions of the first arc plate 343 and the second arc plate 344 align. Figure 10 As shown, the wire harness can be quickly detached from the opening.

[0063] In Example 3, after the wire harness passes through the bow assembly 3, it needs to pass through the traction wheel 43 and the steering wheel assembly 44 repeatedly. During this process, the staff still needs to hold the wire harness. If the wire harness becomes loose during this process, the staff needs to reorganize the wire harness.

[0064] See Figure 9 and Figure 10 Therefore, an arc plate 345 is rotatably connected to one end of the outer side wall of the first arc plate 343, and a pressure roller 346 is installed on the inner wall of the arc plate 345. The pressure roller 346 is used to carry the tape, that is, the tape is sleeved and connected to the outside of the pressure roller 346.

[0065] After the wire harness is positioned and gathered using the first arc plate 343 and the second arc plate 344, the worker first pulls out one end of the tape on the pressure roller 346 and sticks it to the wire harness. Then, by rotating the outer wall of the first arc plate 343 by turning the arc plate 345, the pressure roller 346 rotates, and the tape on the pressure roller 346 wraps around the wire harness, thereby achieving the purpose of binding the wire harness at the end. This process can be carried out simultaneously with the threading of the bow assembly 3. After the wire harness is threaded, the worker only needs to cut the tape and then remove the wire harness from the first arc plate 343 and the second arc plate 344.

[0066] By wrapping tape around the ends of the wire harness, not only is the wire harness wrapped to prevent it from loosening, but also, when the wire harness is driven by the hoop mechanism 34 through multiple U-shaped limiting members, the tape is located at the front end of the first arc plate 343 and the second arc plate 344 in the direction of travel. The tape can be blocked at the constriction position of the first arc plate 343, preventing the wire harness from falling off between the first arc plate 343 and the second arc plate 344.

[0067] Specifically, the outer wall of the first arc plate 343 is provided with an arc plate 345 and a pressure roller 346 structure. After the wire harness is positioned and gathered by the first arc plate 343 and the second arc plate 344, the pressure roller 346 is rotated by moving the arc plate 345, so that the tape on the outside of the pressure roller 346 wraps around the wire harness to achieve end wire binding. This not only prevents the end of the wire harness from loosening, but also prevents the tape from falling between the first arc plate 343 and the second arc plate 344 by placing the tape at the constriction position of the first arc plate 343.

[0068] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
