Description

Technical Field

[0001] This application relates to the field of cable stranding technology, and more particularly to a cable stranding device. Background Technology

[0002] A stranding machine is a mechanical device that can be widely used to strand various soft / hard conductor wires, turning multiple single conductors into one strand to meet the process requirements of wire. Stranding machines can generally be classified according to the stranding method into single stranding machines, double stranding machines, high-speed stranding machines, untwisting machines, cage stranding machines, frame stranding machines, tubular stranding machines, and disc stranding machines, etc.

[0003] First, existing aluminum alloy stranded cable stranding devices work by synchronously rotating and regularly arranging multiple conductors or cores, stranding them around the central core in a set direction and pitch to form a high-strength composite cable. However, traditional stranding equipment often uses fixed guide wheels or static clamping mechanisms. During stranding, the cable is prone to direct friction with the edge of the equipment (such as the outer edge of the mounting block) due to height differences. This continuous contact can lead to scratches on the insulation layer, wear on the metal sheath, and even the risk of local exposure, seriously affecting the insulation performance and service life of the product. Second, during cable stranding, the high-frequency vibrations generated by the equipment operation are transmitted to the cable itself along the mechanical structure. Traditional rigid clamping devices lack elastic buffering design and cannot effectively absorb vibration energy, which may cause microscopic vibration marks to form on the cable surface, affecting the appearance smoothness. Irregular displacement between strands due to vibration can also cause uneven stranding pitch and other problems. Summary of the Invention

[0009] Preferably, the adjustment assembly includes a second drive motor, the output end of which is fixedly connected to a second rotating shaft, one end of which is fixedly connected to a transmission gear, an adjustment plate is provided on one side of the transmission gear, a gear ring is fixedly sleeved on the outer side of the adjustment plate, multiple sets of first adjustment grooves are formed inside the adjustment plate, a rotating plate is movably sleeved inside the adjustment plate, a limit plate is fixedly connected inside the rotating plate, and multiple sets of second adjustment grooves are formed inside the limit plate, with the second adjustment grooves and the first adjustment grooves being staggered.

[0010] Preferably, the adjusting assembly further includes a movable column, which is slidably connected to the inside of the first adjusting groove.

[0011] Preferably, the buffer assembly includes a sliding column, which is fixedly connected to the top of the fixed block. A first spring is movably sleeved on the outer side of the sliding column, and one end of the first spring is fixedly connected to the fixed block. A sliding plate is fixedly sleeved on the outer side of the sliding column. Fixed plates are provided on both sides of the sliding plate, and the sliding plate is slidably connected to the inside of the fixed plates. One end of a second spring is fixedly connected to both sides of the top of the sliding plate, and the other end of the second spring is fixedly connected to a rotating plate. Multiple sets of locking bolts are threaded to the outer side of the adjusting plate, and a winding groove is provided inside the fourth mounting block.

[0012] Preferably, a first support plate is fixedly connected to the other side of the top of the support block, and a guide post is fixedly connected to the top of the first support plate.

[0013] Preferably, the wire assembly includes a mounting base, which is fixedly connected to the top side of the base plate. A second support plate is fixedly connected to the top of the mounting base, and a third drive motor is fixedly connected to one side of the second support plate. A guide wheel and a wire wheel are provided inside the second support plate, and a fifth rotating shaft is rotatably connected inside the second support plate. The wire wheel is fixedly sleeved on the outside of the fifth rotating shaft.

[0014] Preferably, the axes of the winding groove, guide post, guide wheel and guide wheel are on the same axis, and the stranded cable is also located on this axis. By having multiple axes of equal alignment, unnecessary wear caused by deviation during the stranding process can be avoided, thereby protecting the cable.

[0015] The beneficial effects of this invention are as follows: In the cable stranding process, multiple strands of cable are led out from the wire holes of the second winding plate and enter the winding groove to complete the rotational stranding into a cable. During this process, the cable makes contact with multiple sets of pressure rollers. When the second drive motor is started, its power is transmitted step by step through the second rotating shaft, transmission gears, and meshing gear rings, driving the adjusting plate to achieve controllable rotation. The adjusting plate forms a composite guiding mechanism through the first adjusting groove inside and the second adjusting groove of the limiting plate, which precisely guides the moving column to move synchronously in the vertical direction. The movement of the moving column directly drives the pressure rollers to apply dynamic pressure to the cable, causing the stranding point to make a controllable offset relative to the fourth mounting block, thereby making the stranding point... Actively offset to the outer edge of the fourth mounting block to minimize direct friction between the cable and the equipment edge, avoiding scratches on the insulation layer or wear on the metal sheath. It can also be reasonably adjusted according to the material of different cables, and the downward pressure of the pressure roller can be precisely controlled by adjusting the rotation level of the adjustment plate. The optimal compression parameters can be set for different cable characteristics. Due to the downward pressure of the fourth mounting block, the tension of the cable can be further guaranteed during operation. This can effectively prevent strand overlap distortion caused by local slackness, and avoid the risk of metal cold work hardening or fatigue fracture caused by excessive tension, significantly improving the mechanical properties of the finished product.

[0016] During the cable stranding process, high-frequency vibrations are generated due to machine operation and other factors. These vibrations are transmitted to multiple strands of cable. During the stranding process, the vibrations are transmitted to the fixed block through the pressure roller. The fixed block is driven by the pressure roller to produce a slight oscillation. The first spring at the top of the fixed block responds first to the low-frequency basic vibration and effectively eliminates the initial impact energy through elastic deformation. When the vibration amplitude exceeds the set threshold, the sliding plate is activated and drives the second spring to intervene, which absorbs the high-frequency residual vibration a second time. This step-by-step processing mechanism effectively avoids the risk of overload failure of a single elastic element. Compared with the defects of traditional rigid clamping method, which is prone to causing local stress concentration in the cable, the dual springs of this system work together to form a dynamic tension control device. Under normal working conditions, the spring group maintains a constant contact pressure through extension and retraction. When encountering a sudden impact, the spring deformation provides a buffer stroke, ensuring that the cable is always in a controllable pre-tension state. This design not only eliminates vibration patterns on the cable surface, but also controls the outer diameter tolerance of the finished product within a precise range, significantly improving the process quality of the formed cable.

[0017] This invention locks the adjusting plate and the rotating plate by rotating the locking bolt. At this time, the speed of the second drive motor is adjusted to be equal to the rotation speed of the second winding plate. During the twisting process, the cable can be kept in continuous contact with the pressure wheel to prevent it from separating from the pressure wheel during the twisting process. The speed of the second drive motor is strictly synchronized with the second winding plate, so that the surface linear speed of the pressure wheel is almost consistent with the cable feed speed, forming a "zero differential" fit. This synchronization relationship ensures that the cable is always in close contact with the groove surface of the pressure wheel during high-speed twisting, minimizing slippage, jumping or intermittent contact.

After the first rotating shaft 6 rotates, it drives the main shaft 5 to rotate through the transmission of the first pulley 7, the second pulley 8, and the transmission belt 9. After the main shaft 5 rotates, the first winding plate 10 rotates. The rotation of the first winding plate 10 drives the U-shaped mounting block 15 to rotate synchronously through the first connecting plate 11. At the same time, the winding wheel 16 follows the first winding plate 10 to rotate synchronously, thereby twisting the cable.

[0024] The winding assembly includes a first winding plate 10, which is fixedly sleeved on the outside of the main shaft 5. One side of the first winding plate 10 is fixedly connected to one end of multiple sets of first connecting plates 11. One end of a connecting post 12 is fixedly connected to the middle of the first winding plate 10. A second winding plate 13 is fixedly connected to the other end of the multiple sets of first connecting plates 11. The other end of the connecting post 12 is fixedly connected to the second winding plate 13. Multiple sets of wire holes are opened inside the second winding plate 13 to facilitate the guidance and twisting of the cable. Rotating wheels 20 abut against both sides of the second winding plate 13. The top of the base plate 1... Both sides are fixedly connected to a third mounting block 19. The rotating wheel 20 is movably sleeved inside the third mounting block 19. The winding assembly also includes multiple sets of fixing posts 14. The multiple sets of fixing posts 14 are fixedly connected to one side of the first winding plate 10. One end of the first winding plate 10 is fixedly connected to a U-shaped mounting block 15.

A rotating plate 42 is movably sleeved inside the adjustment plate 26. A limit plate 29 is fixedly connected inside the rotating plate 42. Multiple sets of second adjustment grooves 30 are opened inside the limit plate 29. The second adjustment grooves 30 and the first adjustment grooves 28 are staggered. The adjustment assembly also includes a moving column 31, which is slidably connected to the inside of the first adjustment groove 28. One end of the moving column 31 is fixedly connected to a fixing block 32. Hinges 33 are hinged on both sides of the fixing block 32. A U-shaped connecting plate 34 is fixedly connected to the bottom of the hinge block 33. A fixing shaft 35 is fixedly connected to the inner side of the U-shaped connecting plate 34. A pressure wheel 36 is movably sleeved on the outer side of the fixing shaft 35. In the cable stranding process, multiple strands of cable are led out from the wire holes of the second winding plate 13 and enter the winding groove 44 to complete the rotational stranding into a cable. During this process, the cable forms contact with multiple sets of pressure rollers 36. When the second drive motor 23 is started, its power is transmitted step by step through the second rotating shaft 24, transmission gear 25 and meshing gear ring 27, driving the adjusting plate 26 to achieve controllable rotation. The adjusting plate 26 forms a composite guiding mechanism through the internal first adjusting groove 28 and the second adjusting groove 30 of the limiting plate 29, accurately guiding the moving column 31 to move synchronously in the vertical direction. The movement of the moving column 31 directly drives the pressure rollers 36 to apply dynamic pressure to the cable, causing the stranding point to be relative to the fourth mounting block 22. The controllable offset allows the stranding point to actively shift to the outer edge of the fourth mounting block 22, minimizing direct friction between the cable and the equipment edge and preventing scratches on the insulation layer or wear on the metal sheath. It also allows for reasonable adjustment based on the material of different cables. Furthermore, the rotation level of the adjustment plate 26 precisely controls the downward pressure of the pressure roller 36, enabling the setting of optimal compression parameters for different cable characteristics. The downward pressure of the fourth mounting block 22 further ensures cable tension during operation, effectively preventing strand overlap distortion caused by excessive looseness and avoiding the risk of metal cold work hardening or fatigue fracture due to excessive tension, significantly improving the mechanical properties of the finished product.

[0025] The buffer assembly includes a sliding column 37, which is fixedly connected to the top of the fixed block 32. A first spring 38 is movably sleeved on the outside of the sliding column 37. One end of the first spring 38 is fixedly connected to the fixed block 32. A sliding plate 39 is fixedly sleeved on the outside of the sliding column 37. Fixed plates 40 are provided on both sides of the sliding plate 39. The sliding plate 39 is slidably connected to the inside of the fixed plate 40. One end of a second spring 41 is fixedly connected to both sides of the top of the sliding plate 39. The other end of the second spring 41 is fixedly connected to the rotating plate 42. Multiple sets of locking bolts 43 are threadedly connected to the outside of the adjusting plate 26. A winding groove 44 is opened inside the fourth mounting block 22. During the cable stranding process, high-frequency vibrations are generated due to machine operation and other reasons. These vibrations are transmitted to multiple strands of cable. During the stranding process, the vibrations are transmitted to the fixing block 32 through the pressure roller 36. The fixing block 32 is driven by the pressure roller 36 to produce a slight oscillation. The first spring 38 at its top responds first to the low-frequency basic vibration and effectively eliminates the initial impact energy through elastic deformation. When the vibration amplitude exceeds the set threshold, the sliding plate 39 is activated and drives the second spring 41 to intervene, achieving secondary absorption of high-frequency residual vibration. This step-by-step processing mechanism effectively avoids the risk of overload failure of a single elastic element. Compared with the defects of traditional rigid clamping method, which is prone to causing local stress concentration in the cable, the dual springs of this system work together to form a dynamic tension control device. Under normal working conditions, the spring group maintains constant contact pressure through extension and retraction. When encountering a sudden impact, the spring deformation provides a buffer stroke, ensuring that the cable is always in a controllable pre-tension state. This design not only eliminates vibration patterns on the cable surface, but also controls the outer diameter tolerance of the finished product within a precise range, significantly improving the process quality of the formed cable.

[0026] Among them, a first support plate 45 is fixedly connected to the other side of the top of the support block 21, and a guide post 46 is fixedly connected to the top of the first support plate 45; By guiding the cable out of the winding groove 44 through the guide post 46, the axial positioning of the cable can be more accurate, so that the cable can avoid positional deviation during the twisting process, which would affect the twisting effect.

[0027] The wire assembly includes a mounting base 47, which is fixedly connected to the top side of the base plate 1. A second support plate 48 is fixedly connected to the top of the mounting base 47. A third drive motor 49 is fixedly connected to one side of the second support plate 48. A guide wheel 50 and a wire wheel 52 are provided inside the second support plate 48. A fifth rotating shaft 51 is rotatably connected inside the second support plate 48. The wire wheel 52 is fixedly sleeved on the outside of the fifth rotating shaft 51. The guide wheel 50 in the wire clamping assembly works with the guide wheel 52 to guide and clamp the cable. The fixed connection between the fifth rotating shaft 51 and the guide wheel 52 ensures that the guide wheel 52 applies uniform pressure to the cable during rotation, avoiding slippage or displacement of the wire core due to uneven stranding tension. The guide wheel 52 dynamically clamps the cable through drive control, thereby reducing friction and relative movement between the wire cores and preventing damage to the surface oxide film and the generation of metal debris. Through mechanical constraints and dynamic pressure adjustment, this assembly maintains the regular arrangement and stable stranding state of the wire cores during stranding, reducing the risk of wire core twisting or breakage due to plastic deformation.

[0028] Among them, the axes of the winding groove 44, guide post 46, guide wheel 50 and guide wheel 52 are on the same axis, and the stranded cable is also located on this axis. By having multiple axes of equal alignment, unnecessary wear caused by deviation during the stranding process can be avoided, thereby protecting the cable.

[0029] Working principle: The first drive motor 2 serves as the core power output component, driving the first rotating shaft 6 to rotate. After the first rotating shaft 6 rotates, it drives the main shaft 5 to rotate through the transmission of the first pulley 7, the second pulley 8, and the transmission belt 9. After the main shaft 5 rotates, the first winding plate 10 rotates. The rotation of the first winding plate 10 drives the U-shaped mounting block 15 to rotate synchronously through the first connecting plate 11. At the same time, the winding wheel 16 follows the first winding plate 10 to rotate synchronously, thereby twisting the cable. In the cable stranding process, multiple strands of cable are led out from the wire holes of the second winding plate 13 and enter the winding groove 44 for stranding, completing the rotational stranding into a cable. During stranding, the cable is brought into contact with multiple sets of pressure rollers 36 (no stranding action occurs during this process). When the second drive motor 23 is started, its power is transmitted step by step through the second rotating shaft 24, transmission gear 25 and meshing gear ring 27, driving the adjusting plate 26 to achieve controllable rotation. The adjusting plate 26 forms a composite guiding mechanism through the internal first adjusting groove 28 and the second adjusting groove 30 of the limiting plate 29, accurately guiding the moving column 31 to move synchronously in the vertical direction. The movement of the moving column 31 directly drives the pressure rollers 36 to apply pressure to the cable, causing the stranding points to be relatively aligned. The fourth mounting block 22 generates a controllable offset, thereby actively shifting the twisting point to the outer edge of the fourth mounting block 22, minimizing direct friction between the cable and the equipment edge, avoiding scratches on the insulation layer or wear on the metal sheath. It can also be reasonably adjusted according to the material of different cables. Furthermore, the downward pressure of the pressure roller 36 can be precisely controlled by adjusting the rotation level of the adjustment plate 26. The optimal compression parameters can be set for different wire characteristics. Due to the downward pressure of the fourth mounting block 22, the tension of the cable can be further guaranteed during operation. This can effectively prevent strand overlap distortion caused by local slackness and avoid the risk of metal cold work hardening or fatigue fracture caused by excessive tension, significantly improving the mechanical properties of the finished product. After adjustment, the adjusting plate 26 and the rotating plate 42 are locked by rotating the locking bolt 43. At this time, the adjusting plate 26 and the rotating plate 42 are a whole. At the same time, the speed of the second drive motor 23 is adjusted to be equal to the rotation speed of the second winding plate 13. During the twisting process, the cable can be continuously in contact with the pressure wheel 36 to avoid the cable from separating from the pressure wheel 36 during the twisting process. The speed of the second drive motor 23 is strictly synchronized with the second winding plate 13, so that the surface linear speed of the pressure wheel 36 is almost consistent with the cable feed speed, forming a "zero differential" cooperation. This synchronization relationship ensures that the cable is always in close contact with the groove surface of the pressure wheel 36 during high-speed twisting, and eliminates slippage, jumping or intermittent contact as much as possible. During the cable stranding process, high-frequency vibrations are generated due to machine operation and other reasons. These vibrations are transmitted to the multi-strand cable through the connecting components. During the cable stranding process, the vibrations are transmitted to the fixed block 32 through the pressure roller 36. The fixed block 32 is driven by the pressure roller 36 to generate a slight oscillation. The first spring 38 at its top responds first to the low-frequency basic vibration and effectively eliminates the initial impact energy through elastic deformation. When the vibration amplitude exceeds the set threshold, the sliding plate 39 is activated and drives the second spring 41 to intervene and absorb the high-frequency residual vibration. This step-by-step processing mechanism effectively avoids the risk of overload failure of a single elastic element. Compared with the defects of traditional rigid clamping method, which is prone to causing local stress concentration in the cable, the dual springs of this system work together to form a dynamic tension control device. Under normal working conditions, the spring group maintains constant contact pressure through extension and retraction. When encountering a sudden impact, the spring deformation provides a buffer stroke to ensure that the cable is always in a controllable pre-tension state. This design not only eliminates the vibration pattern on the cable surface, but also controls the outer diameter tolerance of the finished product within a precise range, significantly improving the process quality of the formed cable. After winding, the conductors that become a single cable are guided and pressed by the guide wheel 50 and the conductor wheel 52 in the wire pressing assembly. The fixed connection between the fifth rotating shaft 51 and the conductor wheel 52 ensures that the conductor wheel 52 applies uniform pressure to the cable during rotation, avoiding slippage or displacement of the wire core due to uneven stranding tension. The conductor wheel 52 dynamically presses the cable through drive control, thereby reducing friction and relative movement between the wire cores and preventing damage to the surface oxide film and the generation of metal debris. Through mechanical constraints and dynamic pressure adjustment, this assembly maintains the regular arrangement and stable stranding state of the wire cores during stranding, reducing the risk of wire core twisting or breakage due to plastic deformation.
