Description

Technical Field

[0001] This invention relates to the field of wire rope stranding technology, specifically to a wire pressing die for a cable wire rope stranding machine. Background Technology

[0002] In the preparation of cable steel wire rope, multiple steel wires are mainly combined by twisting through a twisting machine. The core working principle of the twisting machine is to rotate the twisting machine and pull it to the pressure die, so that each steel wire is spirally wound around the central axis and twisted into a steel wire rope by the pressure die.

[0003] In traditional twisting processes, high-speed rotating steel wires are prone to localized high temperatures due to intense friction, which leads to accelerated oxidation of the steel wire surface, reduced fatigue life, increased frictional energy consumption, and increased wire breakage rate. Therefore, it is necessary to spray oil on multiple steel wires. However, some of the sprayed oil adheres to the surface of the steel wire, while the rest drips off the surface. The dripping oil cannot be directly reused, resulting in a certain amount of oil waste. Summary of the Invention

[0004] The purpose of this invention is to provide a wire pressing die for a cable wire rope twisting machine, in order to solve the problem mentioned in the background art that in the traditional twisting process, the high-speed rotating steel wire is prone to local high temperature due to severe friction, which leads to accelerated oxidation of the steel wire surface, reduced fatigue life, increased friction energy consumption, and increased wire breakage rate. Therefore, it is necessary to spray oil on multiple steel wires. However, some of the sprayed oil adheres to the surface of the steel wire, while the rest drips off the surface of the steel wire. The dripping oil cannot be directly reused, thus causing a certain amount of oil waste.

[0005] To achieve the above objectives, a wire pressing die for a cable wire rope stranding machine is provided, comprising a base, a conveying mechanism fixedly mounted on one side of the top of the base, the conveying mechanism including a conveying disc fixedly mounted on the top of the base, a support plate fixedly mounted on the side of the top of the base away from the conveying mechanism, a wire pressing mechanism fixedly mounted on the top of the side wall of the support plate, the wire pressing mechanism including a stranding disc fixedly mounted on the top of the side wall of the support plate, an oil spraying mechanism fixedly mounted on the bottom of the side wall of the support plate, the oil spraying mechanism including an oil tank fixedly mounted on the side wall of the support plate, a pump fixedly mounted on the outer wall of the oil tank, an oil suction pipe fixedly mounted on the side end of the pump, the oil suction pipe fixedly penetrating the side wall of the oil tank, a filter cartridge fixedly mounted at the end of the oil suction pipe, an oil delivery pipe fixedly mounted at the output end of the pump, an oil nozzle fixedly mounted at the top of the oil delivery pipe, a recovery port fixedly mounted on the top of the recovery port, and a filter screen snapped into the top of the recovery port.

[0006] By adopting the above technical solution, the pump extracts oil from the oil tank through the oil extraction pipe, and the oil is transported to the oil delivery pipe through the oil extraction pipe, and then to the oil spray nozzle. The oil spray nozzle sprays the oil into the interior of multiple steel wires. This oiling before the steel wires are twisted allows the oil to cover the surface of each steel wire more evenly, effectively solving the problem of insufficient oiling of the inner steel wires and greatly improving the uniformity of oiling. This, in turn, can prevent the steel wire rope from clogging the mold and breaking wires. The dripping oil is collected and filtered through the filter screen. After impurities are removed, the oil falls back into the oil tank through the recovery port. By automatically collecting and filtering the dripping oil, it is convenient to reuse the oil.

[0007] As a further improvement to this technical solution, a plurality of rings are fixedly provided on the outer side wall of the conveyor disk, and guide wheels are fixedly provided on the surface of the plurality of rings respectively. The side wall of the conveyor disk is provided with a plurality of through holes that are respectively connected to the rings.

[0008] By adopting the above technical solution, multiple guide wheels are used to guide and transport multiple steel wires.

[0009] As a further improvement to this technical solution, two support rods are fixedly installed on the side end of the conveyor plate, and limit rings are fixedly installed on the side ends of the two support rods.

[0010] By adopting the above technical solution, the rope core is supported and limited by the limiting ring, so as to prevent the rope core from shifting during transportation.

[0011] As a further improvement to this technical solution, the surface of the twisting disc is provided with a plurality of annularly distributed twisting holes, and a central hole is provided at the center of the twisting disc.

[0012] By adopting the above technical solution, multiple steel wires are passed through multiple twisting holes, and the rope core is passed through the central hole. By bringing multiple steel wires together towards the rope core from different directions, it is easier to twist the wire rope.

[0013] As a further improvement to this technical solution, the side wall of the support plate is provided with a circular groove, the top of the support plate is threadedly connected with a screw rod, including an upper clamping block that is rotatably provided with the bottom end of the screw rod penetrating into the circular groove, a support column is fixedly provided at the bottom of the circular groove, a lower clamping block is fixedly provided at the top of the support column, and a nano-coating is fixedly provided on the inner surface of the upper clamping block and the lower clamping block respectively.

[0014] By adopting the above technical solution, the screw is rotated and moved downwards, which in turn moves the upper clamping block downwards, causing the upper and lower clamping blocks to clamp the wire rope. At this time, the two nano-coatings come into contact with the surface of the wire rope. During the rotation and conveying of the wire rope, the two nano-coatings contact the surface of the wire rope to perform mechanical grinding and polishing, thereby removing scratches on the surface of the wire rope and improving the smoothness of the wire rope surface.

[0015] As a further improvement to this technical solution, an upper protrusion and a lower protrusion are fixedly provided on the side ends of the upper clamping block and the lower clamping block, respectively. A limiting post is fixedly provided on the lower protrusion, and the limiting post slides through the upper protrusion.

[0016] By adopting the above technical solution, the upper protrusion is limited by the limiting post, thereby enabling the upper clamping block to move stably up and down.

[0017] As a further improvement to this technical solution, an installation ring is fixedly provided on the outer edge of the top of the filter screen. The installation ring is located at the top of the recycling port, and the edge of the installation ring extends out of the recycling port.

[0018] By adopting the above technical solution, when it is necessary to clean the filter screen, simply hold the edge of the mounting ring and move the filter screen upwards to easily remove it for cleaning.

[0019] As a further improvement to this technical solution, a filter plate is fixedly installed on the inner side wall of the filter cartridge, and a rotating shaft is rotatably inserted through the center of the filter plate. One end of the rotating shaft extends into the oil extraction pipe and is fixedly installed with an impeller. A scraper is fixedly installed at the end of the rotating shaft away from the impeller, and the scraper is spaced apart from the surface of the filter plate.

[0020] By adopting the above technical solution, the oil is filtered through the filter plate to remove the sediment in the oil, thus preventing the sediment from clogging the fuel injector during oil transport. When the oil flows through the oil extraction pipe, it drives the impeller to rotate, which in turn drives the shaft to rotate. The shaft then drives the scraper to rotate, which removes the sediment adhering to the surface of the filter plate, thereby preventing the filtration speed of the filter plate from decreasing.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting up an oil spraying mechanism, the pump draws oil from the oil tank through the oil extraction pipe. The oil is then transported through the oil extraction pipe to the oil delivery pipe, and then through the oil delivery pipe to the oil spray nozzle. The oil is sprayed into the interior of multiple steel wires through the oil spray nozzle. This oiling before the steel wires are twisted allows the oil to cover the surface of each steel wire more evenly, effectively solving the problem of insufficient oiling of the inner steel wires and greatly improving the uniformity of oiling. This, in turn, can prevent the steel wire rope from clogging the mold and breaking wires. The dripping oil is collected and filtered through a filter screen. After impurities are removed, the oil falls back into the oil tank through the recovery port. By automatically collecting and filtering the dripping oil, it is convenient to reuse the oil.

[0022] 2. By setting up a wire clamping mechanism, the screw is rotated and moved downwards, which in turn moves the upper clamping block downwards, causing the upper and lower clamping blocks to clamp the wire rope. During the rotation and conveying of the wire rope, the two nano-coatings contact the surface of the wire rope for mechanical grinding and polishing, thereby removing scratches on the surface of the wire rope and improving the smoothness of the wire rope surface.

[0027] Please see Figures 1-3 As shown, the purpose of this embodiment is to provide a wire pressing die for a cable wire rope twisting machine, including a base 1. A conveying mechanism 2 is fixedly installed on one side of the top of the base 1. The conveying mechanism 2 includes a conveying disc 21, which is fixedly installed on the top of the base 1. Multiple rings 22 are fixedly installed on the outer wall of the conveying disc 21. Guide wheels 23 are fixedly installed on the surface of the multiple rings 22 respectively. Multiple through holes 24 are provided on the side wall of the conveying disc 21, which are respectively connected to the rings 22. The multiple guide wheels 23 are arranged in a ring array and are adapted to the multiple rings 22 respectively. Two support rods 25 are fixedly installed on the side end of the conveying disc 21. Limiting rings 26 are fixedly installed on the side end of the two support rods 25. The rope core is passed through the limiting rings 26, and the limiting rings 26 support and limit the rope core. Multiple steel wires are passed through the guide wheels 23 into the rings 22 and through holes 24 respectively. During the steel wire conveying process, the corresponding guide wheels 23 are driven to rotate. Multiple guide wheels 23 guide and convey multiple steel wires.

[0028] Please see Figures 2-5As shown, a support plate 3 is fixedly installed on the top of the base 1 away from the conveying mechanism 2. A wire pressing mechanism 4 is fixedly installed on the top of the side wall of the support plate 3. The wire pressing mechanism 4 includes a twisting disc 41, which is fixedly installed on the top of the side wall of the support plate 3. The surface of the twisting disc 41 is provided with multiple annularly distributed twisting holes 411, and a central hole 412 is provided at the center of the twisting disc 41. Multiple steel wires are passed through the multiple twisting holes 411 respectively, and the rope core is passed through the central hole 412. By causing multiple steel wires to pass through different... The wire rope converges towards the core, facilitating wire rope twisting. A circular groove 6 is provided on the side wall of the support plate 3, penetrating the support plate 3 and connecting to the twisting disc 41. A screw 42 is threadedly connected to the top of the support plate 3, including an upper clamping block 43 rotatably mounted on the bottom end of the screw 42, which extends into the circular groove 6. A support column 44 is fixedly mounted at the bottom of the circular groove 6, and a lower clamping block 45 is fixedly mounted at the top of the support column 44. Nano-coatings 46 are fixedly mounted on the inner surfaces of the upper clamping block 43 and the lower clamping block 45, respectively. The wire rope... 6. In the internal twisting process, the screw 42 is rotated and moved downwards, causing the upper clamping block 43 to move downwards, thus clamping the wire rope between the upper clamping block 43 and the lower clamping block 45. At this time, the two nano-coatings 46 come into contact with the surface of the wire rope. During the rotation and conveying of the wire rope, the two nano-coatings 46 mechanically grind and polish the surface of the wire rope, thereby removing scratches on the surface of the wire rope and improving the smoothness of the wire rope surface. As the polishing time increases, the nano-coatings 46 will wear down. At this time, the screw 42 is rotated again and moved downwards, so that the two nano-coatings 46 can effectively contact the surface of the wire rope, thus ensuring the effect of mechanical grinding and polishing. The upper clamping block 43 and the lower clamping block 45 are respectively fixedly provided with an upper protrusion 47 and a lower protrusion 48. A limit post 49 is fixedly provided on the lower protrusion 48. The limit post 49 slides through the upper protrusion 47, limiting the upper protrusion 47, thereby allowing the upper clamping block 43 to move stably up and down.

[0029] Please see Figure 1 , Figure 6 and Figure 7As shown, an oil spraying mechanism 5 is fixedly installed at the bottom of the side wall of the support plate 3. The oil spraying mechanism 5 includes an oil tank 51, which is fixedly installed on the side wall of the support plate 3. A pump 52 is fixedly installed on the outer side wall of the oil tank 51. An oil suction pipe 53 is fixedly installed at the side end of the pump 52, and the oil suction pipe 53 is fixedly installed through the side wall of the oil tank 51. A filter cartridge 531 is fixedly installed at the end of the oil suction pipe 53. An oil delivery pipe 54 is fixedly installed at the output end of the pump 52. An oil spray nozzle 55 is fixedly installed at the top end of the oil delivery pipe 54. The oil spray nozzle 55 is installed on multiple steel wires. Inside and facing the shaft hole 412, during the wire rope twisting process, the pump 52 extracts the oil from the oil tank 51 through the oil extraction pipe 53. The oil is then transported through the oil extraction pipe 53 to the oil delivery pipe 54, and then through the oil delivery pipe 54 to the oil spray nozzle 55. The oil is sprayed into the interior of multiple wires through the oil spray nozzle 55. This oiling before the wires are twisted allows the oil to cover the surface of each wire more evenly, effectively solving the problem of insufficient oiling of the inner wires and greatly improving the uniformity of oiling. This, in turn, can prevent the wire rope from clogging the mold and breaking wires during twisting.

[0030] A recovery port 56 is fixedly installed on the top of the oil tank 51. A filter screen 57 is snapped onto the top of the recovery port 56. An installation ring 571 is fixedly installed on the outer edge of the top of the filter screen 57. The installation ring 571 is located on the top of the recovery port 56, and the edge of the installation ring 571 extends out of the recovery port 56. During the oil spraying process, some oil will drip from the surface of the steel wire. The dripping oil is collected and filtered by the filter screen 57. After impurities are removed, the oil falls into the oil tank 51 through the recovery port 56. By automatically collecting and filtering the dripping oil, it is convenient to reuse the oil. When the filter screen 57 needs to be cleaned, the filter screen 57 can be removed and cleaned by holding the edge of the installation ring 571 and moving it upward.

[0031] Please see Figure 7 As shown, a filter plate 532 is fixedly installed on the inner wall of the filter cartridge 531. A rotating shaft 58 is rotatably inserted through the center of the filter plate 532. One end of the rotating shaft 58 extends into the oil extraction pipe 53 and is fixedly installed with an impeller 581. A scraper 582 is fixedly installed at the end of the rotating shaft 58 away from the impeller 581. A gap is provided between the scraper 582 and the surface of the filter plate 532. The oil enters the oil extraction pipe 53 through the filter cartridge 531 and is filtered by the filter plate 532 to remove sediment from the oil, preventing sediment from being transported with the oil. When the oil is pumped through the oil extraction pipe 53, it drives the impeller 581 to rotate. The impeller 581 drives the shaft 58 to rotate, and the shaft 58 drives the scraper 582 to rotate. The scraper 582 removes the deposits attached to the surface of the filter plate 532, thereby preventing the filtration speed of the filter plate 532 from decreasing. The scraper 582 is 2mm away from the surface of the filter plate 532 to prevent the scraper 582 from directly contacting the filter plate 532 and scraping it, thereby preventing damage to the filter plate 532 and obstruction of the rotation of the scraper 582.

[0032] The working principle of this invention is as follows: The rope core is passed through the limiting ring 26, and then through the shaft hole 412. Multiple steel wires are passed through the guide wheel 23 into the ring 22 and the through hole 24 respectively. The multiple guide wheels 23 guide and transport the multiple steel wires. Then, the multiple steel wires are passed through multiple twist holes 411 respectively. By causing the multiple steel wires to converge towards the rope core from different directions, it is easier to twist the wire rope. The pump 52 draws oil from the oil tank 51 through the oil extraction pipe 53. The oil enters the oil extraction pipe 53 through the filter cartridge 531 and is filtered by the filter plate 532 to remove the sediment in the oil, preventing the sediment from clogging the oil nozzle 55 during oil transportation. The oil is transported through the oil extraction pipe 53 to the oil delivery pipe 54, and then through the oil delivery pipe 54 to the oil spray nozzle 55. The oil is sprayed into the interior of multiple steel wires through the oil spray nozzle 55. This oiling before the steel wires are twisted allows the oil to cover the surface of each steel wire more evenly, effectively solving the problem of insufficient oiling of the inner steel wires and greatly improving the uniformity of oiling. This can prevent the steel wire rope from clogging the mold and breaking wires during twisting. During the oiling process, some oil will drip from the surface of the steel wires. The dripping oil is collected and filtered through the filter screen 57. After impurities are removed, the oil falls into the oil tank 51 through the recovery port 56. By automatically collecting and filtering the dripping oil, it is convenient to reuse the oil.
