Description

Technical Field

[0001] The present application relates to the technical field of cable stranding equipment, and in particular to a stranding device. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of conductors (at least two in each group). Each group of conductors is insulated from each other and often twisted around a center wire. The entire outside is covered with a highly insulating covering. During the cable processing process, a stranding machine first twists several conductors into a thicker conductor, and then a wrapping machine wraps the insulating cloth around the outside of the thicker cable.

[0003] The utility model patent with authorization announcement number CN209591662U discloses a wire stranding machine, including a base, on which a wire feeding device, a wire stranding device, a wire pressing device, a guiding device and a wire taking-up device are sequentially arranged along the wire transportation direction.

[0004] The wire feeding device feeds the center wire into the wire twisting device. Under the action of the die of the wire pressing device, multiple cables are twisted on the center wire. Finally, the stranded wire is fed into the wire taking-up device through the guide device for taking-up, thus completing the stranding process.

[0005] However, when the stranded wire enters the die in the wire crimping device, friction is generated between the stranded wire and the die. As the stranded wire continues to be pulled forward, not only will the stranded wire be worn, but the stranded wire will also be easily stuck in the wire crimping device. Summary of the invention

[0006] In order to allow the stranded wire to pass through the die smoothly and increase the service life of the stranded wire, the present application provides a stranding device.

[0007] The present application provides a wire stranding device, which adopts the following technical solution:

[0008] A wire stranding device comprises a center line feeding module, a wire stranding module, a die module and a wire take-up module which are arranged in sequence, a receiving tray for installing a lubricant is arranged on the outer peripheral side of the die module, a suction pipe is arranged on the feed side of the die module, the suction pipe is arranged in the receiving tray, a liquid outlet pipe is arranged on one side of the suction pipe, and the suction pipe is provided with a suction mechanism for extracting the lubricant.

[0009] By adopting the above technical solution, when it is necessary to twist the wires, the center wire is transmitted to the twisting module through the center wire feeding module, and then the multiple cables are respectively wound around the center wire through the twisting module, and then the twisted cables are punched through the die module to form the required diameter. During the die forming process, the suction mechanism draws the lubricant onto the suction tube, and the lubricant continues to flow out through the liquid outlet tube toward the feed side of the die module. At this time, the lubricant lubricates the wound cables, and finally the cables are wound up through the take-up module. Under the action of the lubricant, not only can the cables pass through the die smoothly to prevent being stuck, but also the service life of the cables can be extended.

[0010] Optionally, the suction mechanism includes a piston, a feeding pipe is provided at the bottom end of the suction tube, a first material stopper is provided on the inner wall of the bottom end of the suction tube, one end of the first material stopper is fixedly provided on the inner bottom wall of the suction tube, and the other end of the first material stopper covers the top end of the feeding tube, the piston is slidably provided in the suction tube, a through hole is penetrated through the bottom surface of the piston, a second material stopper is provided in the piston, one end of the second material stopper is fixedly provided on the top surface of the piston, and the other end of the second material stopper covers the through hole, and the receiving tray is provided with a driving component for driving the piston to rise and fall.

[0011] By adopting the above technical solution, when the driving assembly drives the piston to rise, under the action of atmospheric pressure, the lubricant is sucked into the suction tube, and then pushes open the first blocking member and enters the suction tube. When the driving assembly drives the piston to descend, the lubricant in the suction tube pushes open the second blocking member and enters above the piston. This is repeated, and finally the lubricant flows out from the liquid outlet pipe, which is beneficial to improve the stability of the lubricant outflow.

[0012] Optionally, the driving assembly includes a turntable, a bracket is arranged on the receiving plate, the turntable is rotatably arranged on the bracket, a connecting rod is eccentrically arranged on one side of the turntable, the end of the connecting rod away from the turntable is hinged to the piston, and the bracket is provided with a transmission part for driving the turntable to rotate.

[0013] By adopting the above technical solution, when the transmission member drives the turntable to rotate, the turntable drives the eccentrically arranged connecting rod to move. Under the guidance of the suction tube, the connecting rod drives the piston to reciprocate and rise and fall in the suction tube, which is beneficial to improve the stability of the reciprocating movement of the piston.

[0014] Optionally, a fixing frame is provided on the discharge side of the die module, the fixing frame is fixedly connected to the inner wall of the receiving tray, a guide ring is provided on the fixing frame, and a scraper is provided on one side of the guide ring.

[0015] By adopting the above technical solution, when the cable is discharged from the discharge side of the die module, the cable is inserted into the guide ring, and when the cable is passed out from the guide ring, the scraper scrapes the lubricant on the cable and collects it in the receiving tray for recycling, which is beneficial to reduce the lubricant dripping on the subsequent processing position and polluting the equipment and the processing environment.

[0016] Optionally, the scraper includes a plurality of plastic sheets, and the plurality of plastic sheets are all arranged on one side of the guide ring, and the plurality of plastic sheets enclose a penetration space, a rubber belt is arranged in the penetration space, a clamping block is arranged on the outer side of the rubber belt, and a clamping groove is opened on the inner side of the plurality of plastic sheets, and the clamping block is clamped in the clamping groove.

[0017] By adopting the above technical solution, when the cable passes through the guide ring, the cable is inserted into the passing space, and at this time, multiple plastic sheets are adaptively adjusted according to the diameter of the cable, which is conducive to adapting to the processing of cable strands with different diameters. Multiple plastic sheets simultaneously open the rubber belt, so that the rubber belt is sleeved on the side wall of the cable. In the process of continuous forward pulling of the cable, the rubber belt scrapes off the lubricant on the cable, which is conducive to improving the stability of scraping off the lubricant. When the rubber belt needs to be replaced, the rubber belt can be replaced by removing the card block from the card slot, which is conducive to improving the removability of the rubber belt.

[0018] Optionally, a connecting frame is provided on the side of the receiving tray facing away from the stranding module, and an adjusting wheel and two positioning wheels are provided on the connecting frame. The two positioning wheels are symmetrically arranged on both sides of the adjusting wheel, and the connecting frame is provided with an adjusting member for cooperating to drive the adjusting wheel to move.

[0019] By adopting the above technical solution, the cable passing through the receiving tray first passes through a positioning wheel, then is wound around the adjusting wheel, and then is wound around another positioning wheel. When the cable becomes loose or tense during the traction process, the cable drives the adjusting wheel to move and adjust under the cooperation of the adjusting member, and finally the cable maintains a moderate tension, reducing the possibility of cable breakage.

[0020] Optionally, the adjusting member is a spring, an adjusting slot is opened in the connecting frame, a wheel seat is movably arranged in the adjusting slot, the wheel seat extends outside the adjusting slot, the adjusting wheel is rotatably arranged in the wheel seat, the spring is arranged in the adjusting slot, one end of the spring is connected to the slot wall of the adjusting slot, and the other end of the spring is connected to the wheel seat.

[0021] By adopting the above technical solution, when the cable is slack, the spring tightens and drives the wheel seat to rise, and the wheel seat thereby drives the cable to rise, thereby tightening the cable. When the cable is over-tightened, the cable drives the wheel seat to descend through the adjusting wheel, and the wheel seat thereby stretches the spring, thereby buffering the tension of the cable, which is beneficial to improving the stability of the cable tension adjustment.

[0022] Optionally, the transmission member includes a first transmission wheel, a second transmission wheel and a transmission belt, the first transmission wheel is coaxially arranged on one side of one of the positioning wheels, the second transmission wheel is coaxially arranged on one side of the turntable, and the transmission belt is simultaneously connected to the first transmission wheel and the second transmission wheel.

[0023] By adopting the above technical solution, when the cable passes through one of the positioning wheels, the cable drives one of the positioning wheels to rotate, and the positioning wheel then drives the coaxial first transmission wheel to rotate. Under the transmission action of the transmission belt, the transmission belt drives the second transmission wheel to rotate, and the second transmission wheel then drives the coaxial rotation, thereby utilizing the traction force of the cable to reduce the use of electrical equipment.

[0024] Optionally, the wire taking-up module includes a wire taking-up frame, a winding roller is rotatably arranged inside the wire taking-up frame, a guide frame is arranged on the front side of the wire taking-up frame, a reciprocating screw is rotatably arranged inside the guide frame, a limit rod is arranged inside the guide frame, and a guide cylinder is threadedly connected to the reciprocating screw.

[0025] By adopting the above technical solution, when the reciprocating screw rotates, the reciprocating screw drives the guide cylinder to move back and forth along the direction of the guide frame. Under the action of the guide cylinder, the cable is evenly wound on the winding roller, which is beneficial to improve the stability and flatness of the winding roller when winding the cable.

[0026] Optionally, a cable straightener is provided between the die module and the wire taking-up module.

[0027] By adopting the above technical solution, after the cable punching is completed, the cable is pulled into the cable straightener. Under the action of the cable straightener, the surface of the cable will be subjected to vertical pressure, which effectively removes the memory of the spool rolled before winding and prevents the twisted cable from loosening.

[0028] In summary, this application includes the following beneficial technical effects:

[0029] When it is necessary to twist the wires, the center wire is transmitted to the twisting module through the center wire feeding module, and then the multiple cables are respectively wound on the center wire through the twisting module, and then the twisted cables are punched through the die module to form the required diameter. During the die forming process, the suction mechanism draws the lubricant onto the suction tube, and the lubricant continues to flow out through the liquid outlet tube toward the feed side of the die module. At this time, the lubricant lubricates the wound cables, and then the cables are pulled out from the receiving tray, and then the cable straightener straightens the cables, and finally the cable is wound through the take-up module. Under the action of the lubricant, not only can the cables pass through the die smoothly to prevent being stuck, but also the service life of the cables can be extended.

[0037] The following is combined with Figure 1-6 This application is described in further detail.

[0038] Example:

[0039] See also Figure 1 A wire stranding device comprises a center wire feeding module 1, a wire stranding module 2, a die module 3 and a wire take-up module 4 which are sequentially arranged in a straight line. The center wire feeding module 1 is used to provide the center wire to be wound to the wire stranding module 2. The wire stranding module 2 is used to place a plurality of wire coils, and simultaneously wind the steel wires on the plurality of wire coils onto the center cable, thereby preliminarily forming a cable. The die module 3 is used to punch the preliminarily formed cable, so that the wound cables are die-processed to the required diameter. The wire take-up module 4 is used to roll up the cable after the die processing, and finally complete the wire stranding processing.

[0040] In the above process, the center wire feeding module 1, the stranding module 2, the die module 3 and the wire taking-up module 4 all belong to the prior art and will not be described in detail here.

[0041] Among them, see Figure 2 The die module 3 includes a feed side and a discharge side, and a receiving tray 5 is arranged on the periphery of the die module 3, and the receiving tray 5 is used to contain lubricant. A suction pipe 6 is fixed in the receiving tray 5, and the suction pipe 6 is vertically arranged, and the suction pipe 6 is located on the feed side of the die module 3. The side wall of the suction pipe 6 is fixedly connected with a liquid outlet pipe 7, and the liquid outlet pipe 7 is aligned with the feed side of the die module 3, and the suction pipe 6 is installed with a suction mechanism, and the suction mechanism is used to suck the lubricant in the receiving tray 5 to the suction pipe 6.

[0042] When the cable enters the die after winding, the lubricant is sucked onto the suction pipe 6 through the suction mechanism, and then flows out to the feeding side of the die module 3 through the liquid outlet pipe 7 and drips onto the cable. Under the lubricating effect of the lubricant, the cable can not only pass through the die module 3 smoothly without being stuck, but also extend the service life of the cable.

[0043] For details, see Figure 3 , the suction mechanism includes a piston 8. The bottom end of the suction pipe 6 is fixedly connected to the feed pipe 9, and the bottom end of the feed pipe 9 extends into the lubricant of the receiving tray 5. A first material stopper 10 is installed on the inner bottom wall of the suction pipe 6, one end of the first material stopper 10 is fixed to the inner bottom wall of the suction pipe 6 by bolts, and the other end of the first material stopper 10 covers the top of the feed pipe 9. The piston 8 is slidably connected in the suction pipe 6, and a through hole 11 is penetrated through the bottom surface of the piston 8. The piston 8 connects the suction pipe 6 as a whole through the through hole 11. A second material stopper 12 is installed in the piston 8, and the second material stopper 12 is located on the top surface of the through hole 11. One end of the second material stopper 12 is fixed to the top surface of the piston 8 by bolts, and the other end of the second material stopper 12 covers the through hole 11.

[0044] It should be noted that the first material stopper 10 and the second material stopper 12 are made of hard colloid material, and the fixed ends of the first material stopper 10 and the second material stopper 12 are both provided with folds to facilitate the first material stopper 10 and the second material stopper 12 to be opened.

[0045] See also Figure 3 In order to facilitate the piston 8 to move up and down in the suction pipe 6, the receiving tray 5 is equipped with a driving assembly, and the driving assembly includes a rotating disk 13. A bracket 14 is fixed on the receiving tray 5, and the rotating disk 13 is located above the suction pipe 6, and the rotating disk 13 is rotatably mounted on the bracket 14. A connecting rod 15 is installed on one side of the rotating disk 13, one end of the connecting rod 15 is eccentrically hinged to the rotating disk 13, and the other end of the connecting rod 15 is hinged to the piston 8.

[0046] When the turntable 13 rotates, the turntable 13 drives the connecting rod 15 to move. Since the connecting rod 15 is eccentrically hinged with the turntable 13, the connecting rod 15 drives the piston 8 to move up and down reciprocatingly under the continuous rotation of the turntable 13. When the piston 8 moves upward, under the action of atmospheric pressure, the lubricant in the receiving tray 5 is first sucked onto the feed pipe 9, and then the lubricant pushes up the first material stopper 10 and enters the suction pipe 6. And when the piston 8 moves downward, the lubricant in the suction pipe 6 squeezes the first material stopper 10 and makes the first material stopper 10 cover the feed pipe 9; at the same time, the lubricant in the suction pipe 6 also pushes up the second material stopper 12, so that the lubricant enters the top of the piston 8. The piston 8 is repeatedly lifted and lowered in this way, and the lubricant finally flows out from the liquid outlet pipe 7 and lubricates the cables on the feed side of the die module 3.

[0047] See also Figure 2 and Figure 4 When the wound cable is processed by the die module 3, the cable is covered with lubricant. In order to reduce the lubricant from dripping on the ground and dripping into the subsequent modules, a fixing frame 16 is installed on the discharge side of the die module 3, and the fixing frame 16 is fixedly connected to the inner wall of the receiving tray 5. A guide ring 17 is fixed to the end of the fixing frame 16 away from the receiving tray 5. The guide ring 17 is horizontally arranged and can be passed through by the cable with the largest diameter. A scraper 18 is fixed to the end of the guide ring 17 away from the die module 3, and the scraper 18 is used to scrape the lubricant on the cable.

[0048] After the wound cable passes through the die module 3, the cable passes through the guide ring 17 and is continuously pulled forward. At this time, the scraper 18 scrapes off the lubricant on the cable, and the scraped lubricant is collected again in the receiving tray 5 for recycling.

[0049] See also Figure 4In order to scrape off lubricants from cables of different diameters, the scraper 18 includes a plurality of plastic sheets 19. In this embodiment, there are three plastic sheets 19, which enclose a through-space for the cable after the die to pass through, and the three plastic sheets 19 and the guide ring 17 are in a cone shape as a whole. A rubber band 20 is installed in the through-space, and a clamping block 21 is fixed to the outer wall of the rubber band 20. A clamping groove 22 is provided on the inner side of the three plastic sheets 19 corresponding to the position of the clamping block 21, and the clamping block 21 is clamped with the clamping groove 22.

[0050] When the cable after the die punching passes through the insertion space, the cable simultaneously stretches the three plastic sheets 19, and the three plastic sheets 19 also simultaneously stretch the rubber belt 20. In the process of the cable being pulled forward, the rubber belt 20 is tightly wrapped around the side wall of the cable, and the rubber belt 20 scrapes off the lubricant on the cable. It should be noted that the lubricant scraped off by the rubber belt 20 drips from the gaps between the plastic sheets 19 under the diversion effect of the plastic sheets 19 and is collected in the receiving tray 5.

[0051] See also Figure 2 and Figure 5 In order to reduce the possibility of cable breakage during the traction process, a connecting frame 23 is fixed on the side of the receiving tray 5 away from the stranding module 2, and an adjusting wheel 24 and two positioning wheels 25 are rotated on the connecting frame 23. The adjusting wheel 24 is located above the two positioning wheels 25, and the two positioning wheels 25 are symmetrically arranged with the adjusting wheel 24 as the center. After the lubricant is scraped off, the cable first passes through the bottom of one of the positioning wheels 25, then is wound on the top of the adjusting wheel 24, and then is wound on the bottom of the other positioning wheel 25, and finally is pulled to the next process.

[0052] See also Figure 5 In order to facilitate the adjustment wheel 24 to adjust the tension of the cable, the connecting frame 23 is provided with an adjustment member, which is a spring 26. An adjustment slot 27 is provided in the connecting frame 23, and a wheel seat 28 is movable in the adjustment slot 27, and the wheel seat 28 extends outside the adjustment slot 27. The adjustment wheel 24 rotates in the wheel seat 28, and the spring 26 is installed in the adjustment slot 27, one end of the spring 26 is fixedly connected to the slot wall of the adjustment slot 27, and the other end of the spring 26 is fixedly connected to the wheel seat 28.

[0053] When the cable is too tight, the cable drives the adjusting wheel 24 down, and the adjusting wheel 24 drives the spring 26 to stretch through the wheel seat 28, thereby alleviating the over-tightening of the cable. When the cable is loose, the spring 26 contracts and drives the wheel seat 28 to retract into the adjusting slot 27, and the wheel seat 28 drives the adjusting wheel 24 to move up, thereby alleviating the loosening of the cable.

[0054] It is worth mentioning that see Figure 2In order to facilitate the rotation of the turntable 13 and reduce the use of electrical equipment, the bracket 14 is equipped with a transmission member. The transmission member includes a first transmission wheel 29, a second transmission wheel 30 and a transmission belt 31. The first transmission wheel 29 is coaxially fixed to one side of one of the positioning wheels 25, the second transmission wheel 30 is coaxially fixed to the side of the turntable 13 away from the connecting rod 15, and the transmission belt 31 is transmission-sleeved on the outer sides of the first transmission wheel 29 and the second transmission wheel 30.

[0055] As the cable continues to be pulled forward, the cable drives one of the positioning wheels 25 to rotate, and one of the positioning wheels 25 drives the coaxially fixed first transmission wheel 29 to rotate. Under the transmission action of the transmission belt 31, the transmission belt 31 drives the second transmission wheel 30 to rotate, and the second transmission wheel 30 thereby coaxially drives the turntable 13 to rotate.

[0056] It should be noted that since the cable has a memory of being wound on the spool before winding, and the cable is also wound around the adjustment wheel 24, the twisted cable is easy to loosen. Figure 1 A cable straightener 38 is installed between the punching die module 3 and the wire taking-up module 4. The principle of the cable straightener 38 is mainly to apply pressure on the top surface of the cable through a pressure wheel to straighten the cable. And the cable straightener 38 is a common device on the market.

[0057] For details, see Figure 1 and Figure 6 The wire-receiving module 4 includes a wire-receiving frame 32, in which a winding roller 33 rotates, and the winding roller 33 is used to reel in the straightened cable. In addition, in order to facilitate the cable to be smoothly reeled on the surface of the winding roller 33, a guide frame 34 is installed in front of the wire-receiving frame 32, in which a reciprocating screw 35 rotates, a limit rod 36 is fixed in the guide frame 34, a guide cylinder 37 is threadedly connected to the reciprocating screw 35, the guide cylinder 37 is slidably connected to the limit rod 36, and the cable is plugged into the guide cylinder 37.

[0058] When the reciprocating screw 35 rotates, under the limiting action of the limiting rod 36 , the reciprocating screw 35 drives the guide cylinder 37 to move back and forth. Under the guiding action of the guide cylinder 37 , the cable is evenly wound on the winding roller 33 .

[0059] Working principle of a wire twisting device:

[0060] When twisting the wires, firstly, the center cable is fed into the twisting module 2 through the center wire feeding module 1, and then the twisting module 2 is started, so that the twisting module 2 winds the other cables around the center cable. The wound cables are then pulled into the feed side of the die module 3. In the process of the cables entering the feed side of the die module 3, the turntable 13 rotates under the transmission action of the first transmission wheel 29, the second transmission wheel 30 and the transmission belt 31, and the turntable 13 drives the piston 8 to rise and fall back and forth through the connecting rod 15. When the piston 8 rises, under the action of the atmospheric pressure, the lubricant is sucked into the feed pipe 9, and the lubricant then pushes the first material stopper 10 upward through the feed pipe 9 and is sucked into the suction pipe 6. When the piston 8 descends, the air pressure closes the first material stopper 10, and the lubricant in the suction pipe 6 pushes the second material stopper 12 open. Repeating this process, more and more lubricants enter the suction pipe 6, and finally flow out from the liquid outlet pipe 7, and finally drip on the cable to lubricate the cable.

[0061] After the cable is pulled out from the discharge side of the die module 3, the cable passes through the guide ring 17 and then passes through the penetration space formed by the three plastic sheets 19. At this time, the rubber belt 20 in the plastic sheet 19 scrapes off the lubricant on the cable and collects it again in the receiving tray 5.

[0062] In summary, dripping lubricant onto the cable can help the stranded wire pass through the die smoothly, thereby increasing the service life of the stranded wire.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
