[0002] The stranding device is required in the production process of hydraulic hoses. The stranding device includes components such as a stranding machine, a wire distribution disc, a wire crimping die, an oil dripping box, and an oil pump. The stranding machine is responsible for outputting the steel wire, the wire distribution disc is used to separate the steel wire, and the wire crimping die is used for stranding and outputting the steel wire. An oil dripping ring is fixed inside the oil dripping box, on which multiple nozzles are evenly spaced. The spray direction of the nozzle is toward the center of the oil dripping ring. The oil is pumped from the oil storage tank through the oil pump to provide lubrication for the steel wire. However, the position of the nozzle is fixed, which can easily lead to insufficient contact between the oil and the steel wire, reducing the lubrication effect on the steel wire, causing wear when the steel wire is introduced into the wire crimping die for stranding, and reducing the quality of the steel wire stranding processing of the hydraulic hose by the stranding device.

[0003] Example (authorization announcement number CN212052085U) A steel wire stranding equipment for hydraulic hose production, including a stranding machine, a wire dividing disk and a wire crimping die. The steel wire output by the stranding machine passes through the wire dividing disk and the wire crimping die in turn and is stranded and output from the wire outlet end of the wire crimping die as steel wire rope strands; it also includes an oil dripping box and an oil pump. The oil dripping box is arranged between the wire dividing disk and the wire crimping die. The steel wire after wire dividing passes through the interior of the oil dripping box and enters the wire crimping die. An oil dripping ring is fixedly arranged inside the oil dripping box. The oil dripping ring includes a ring body. The steel wire passes through the interior of the ring body. A plurality of nozzles are evenly spaced along the circumference of the ring body on the ring body. The nozzles are connected to the interior of the ring body and the spray direction of the nozzles is toward the center of the ring body.

The wire stranding is achieved by introducing the steel wire into the wire crimping die body 1. A linear motor 3 is installed on the inner top wall of the support plate 2. The fixed end of the linear motor 3 is detachably connected to the inner top wall of the support plate 2 by bolts. The moving part of the linear motor 3 is detachably connected to a movable frame 4 by bolts, so that the movable frame 4 can be driven to move horizontally during the movement of the moving part of the linear motor 3. The inner side wall of the movable frame 4 is movably connected to a movable block 5, so that the movable block 5 can rotate and move relatively along the inner side wall of the movable frame 4.

[0029] The two end surfaces of the movable block 5 are welded with a limit block 6 and a connecting plate 7 respectively. The adjacent sides of the limit block 6 and the connecting plate 7 are in sliding friction contact with the movable frame 4. The limit block 6 and the connecting plate 7 are set to prevent the movable frame 4 from separating from the movable block 5, thereby improving the structural stability of the device parts. The bottom surface of the connecting plate 7 is fixedly connected to an oil delivery ring 8 with an annular inner cavity inside. The inner ring surface of the oil delivery ring 8 is connected to a plurality of nozzles 9 for spraying oil for lubricating the steel wire to be stranded, so that the steel wire of the hydraulic hose passes through the oil delivery ring 8. The oil is sprayed on the surface of the steel wire of the hydraulic hose through a plurality of nozzles 9, thereby providing lubrication for the steel wire, preventing the steel wire from being worn when it is introduced into the inside of the wire crimping die body 1 for stranding processing, and reducing the stranding processing quality of the hydraulic hose steel wire by the stranding device.

[0030] The side of the oil delivery ring 8 is rotatably connected with an arc-shaped limit plate 10, and the arc-shaped notch of the limit plate 10 is smaller than a semicircle, so that the oil delivery ring 8 can be fixed in the longitudinal direction through the limit plate 10.

[0032] The inner wall of the filter frame 16 is fixedly connected to the filter screen 17, and the filter frame 16 is provided to provide support for the filter screen 17. The outer wall of the filter frame 16 is slidably connected to the inner wall of the collection box 14. At the same time, the connection between the filter frame 16 and the collection box 14 is sealed to prevent impurities mixed in the oil from flowing into the collection box 14 through the connection gap, thereby improving the structural stability of the device parts. L-shaped fixing plates 18 are welded at both ends of the top of the filter frame 16, and a magnetic plate 19 is fixedly connected to the inner top wall of the fixing plate 18. The end surface of the magnetic plate 19 extends into The side wall of the collecting box 14 and the top surface of the side wall of the collecting box 14 are provided with grooves, so that the magnetic plate 19 can be extended into the groove of the collecting box 14. At the same time, the collecting box 14 is made of martensitic stainless steel after heat treatment, which is rust-proof and convenient for realizing the magnetic connection between the collecting box 14 and the magnetic plate 19. The side of the magnetic plate 19 is magnetically connected to the collecting box 14, which is convenient for fixing the position of the filter 17 during the transmission process, and convenient for disassembling and cleaning the filter 17 to prevent debris from clogging the filter 17, which makes it inconvenient to recycle and reuse the oil.

[0033] A pump body 13 for extracting oil is installed on the side of the collecting box 14. The fixed end of the pump body 13 is detachably connected to the side of the collecting box 14 by bolts. The output shaft of the pump body 13 is connected to a soft conduit 12. The outer peripheral side of the conduit 12 is connected to the oil delivery ring 8. The input end of the pump body 13 extends into the collecting box 14, so that the input end of the pump body 13 extracts the oil inside the collecting box 14 and introduces it into the conduit 12, and then introduces the oil into the inner cavity of the oil delivery ring 8, and then the oil is sprayed out through a plurality of nozzles 9. The shell side of the wire crimping die body 1 is fixedly connected to the collecting box 14.

[0034] The linear motor 3 and the pump body 13 are both prior arts.

[0036] When the user uses the wire stranding device, the user drives the linear motor 3 to move the movable frame 4, and the limit plate 10 fixes the longitudinal position of the oil delivery ring 8. Then, under the connection between the connecting plate 7 and the movable block 5, the oil delivery ring 8 is driven to rotate back and forth, increasing the area of ​​the oil sprayed by the plurality of nozzles 9, achieving full contact between the wire and the oil, preventing the wire from being worn, and improving the stranding processing quality of the hydraulic hose wire by the stranding device. The limit block 6 is provided to prevent the movable block 5 from detaching from the movable frame 4.

[0037] The oil falling from the oil transfer ring 8 is collected by the set collection box 14, and the set filter assembly 15 filters the oil so that the oil falls to the top surface of the filter screen 17, and the oil flows into the collection box 14. The impurities are retained on the top surface of the filter screen 17 to achieve the filtering effect on the oil. The filter frame 16 provides support for the filter screen 17, so that the magnetic plate 19 extends into the side wall of the collection box 14, and the magnetic plate 19 is magnetically connected to the collection box 14, so as to fix the position of the filter screen 17, and at the same time facilitate the disassembly and cleaning of the filter screen 17, thereby improving the convenience of using the device.
