Description

Technical Field

[0001] The utility model belongs to the technical field of ultrafine silver-plated wire production, and specifically relates to a wire drawing mechanism for ultrafine silver-plated wire production. Background Technique

[0002] Silver-plated wire is sometimes called silver-plated copper wire or silver-plated wire. It is a thin wire made by plating silver on an oxygen-free copper wire or a low-oxygen copper wire and then drawing it thinner by a wire drawing machine.

[0003] The prior art discloses a wire drawing machine for silver-plated soft copper wire production (CN211100827U), which solves the drawback in the prior art that wire drawing needs to be repeated multiple times. It includes a machine case and a wire take-up shaft. A horizontal wire pay-off reel, a first steering shaft, a second steering shaft and a wire take-up reel are rotatably connected to the machine case. The second steering shaft is located below the wire pay-off reel, and the wire take-up reel is located below the first steering shaft. A first wire drawing die bolted to the machine case is arranged between the first steering shaft and the second steering shaft, and the horizontal plane where the lower section of the first steering shaft, the upper section of the second steering shaft and the central axis of the first wire drawing die are located is coplanar. A second wire drawing die bolted to the machine case is arranged below the first wire drawing die.

[0004] After retrieval, it is found that when the device is in use, the distances between the first steering shaft and the second steering shaft cannot be controlled, which results in insufficient steering tension between the first steering shaft and the second steering shaft, thus affecting the uniformity of silver-plated wire drawing and the use of the device. In addition, the wire take-up reel used in this device winds the wire by rotation, which easily causes the deviation of the wire take-up position of the silver-plated wire, and then makes the wire take-up uneven, thus causing the winding of the silver-plated wire and affecting the subsequent use of the silver-plated wire.

There are two sliders 23, the first steering shaft 22 and the second steering shaft 27 are respectively fixedly connected to different sliders 23, the sliders 23 are slidably arranged in the support plate 10, the clamping block 28 is movably connected to one side of the slider 23, and the clamping block 28 is clamped to the support plate 10; a wire take-up structure, the wire take-up structure is fixedly arranged on one side of the support plate 10, and the wire take-up structure includes a fixed plate 14, a fixed rack 15, a crank 17, a gear 18, a connecting rod 19 and a moving block 20. The fixed plate 14 is fixedly connected to the support plate 10 and the fixed rack 15, the connecting rod 19 is rotatably connected to the crank 17 and the gear 18, the crank 17 is rotatably arranged on the same side where the fixed plate 14 is connected to the fixed rack 15, the moving block 20 is slidably arranged inside the fixed plate 14, and both the fixed rack 15 and the moving block 20 are in transmission connection with the gear 18.

[0031] The working principle is as follows. The wire pay-off shaft 21, the first steering shaft 22, and the second steering shaft 27 are similar in shape. Ring openings with gradually decreasing aperture sizes from large to small are provided on the wire pay-off shaft 21, the first steering shaft 22, and the second steering shaft 27, and the sizes of the ring openings on the three are also different, arranged in the form that the wire pay-off shaft 21 is larger than the first steering shaft 22 which is larger than the second steering shaft 27. During use, by setting a distance-adjusting structure, by controlling the movement of the slider 23, the position of the first steering shaft 22 and the second steering shaft 27 is adjusted using the clamping block 28, thereby controlling the distances between the first steering shaft 22, the second steering shaft 27 and the wire pay-off shaft 21, thereby adjusting the steering tension of the silver-plated wire, thereby ensuring the uniformity of the silver-plated wire drawing, and thus ensuring the use of the device; by setting a wire take-up structure, the rotation of the crank 17 is used to drive the rotation of the connecting rod 19, and the connecting rod 19 is used to pull the meshing transmission between the gear 18, the fixed rack 15, and the moving block 20, so that the moving block drives the reciprocating movement of the silver-plated wire, thereby ensuring the stability of the wire take-up position of the silver-plated wire, and further making the wire take-up uniform, thereby avoiding the winding of the silver-plated wire, and further ensuring the later use of the silver-plated wire.

[0032] As Figure 1 and Figure 5 shown, two square chutes are opened inside the support plate 10, and two wire drawing dies 26 are fixedly arranged between the two square chutes. The two wire drawing dies 26 are fixedly connected to the support plate 10. Three through holes are opened at the top of the support plate 10, and an oil dripping pipe 25 is clamped in the through holes. The oil dripping pipe 25 is composed of three round pipes and one square pipe. The three round pipes are respectively clamped in the three through holes, and an oil delivery hose 24 for lubricating oil delivery is fixedly arranged inside the square pipe; As Figure 1 and Figure 2 shown, a wire pay-off shaft 21 is arranged above the oil sump 11. The wire pay-off shaft 21 is fixedly connected to the support plate 10. The fixed plate 14 and the wire pay-off shaft 21 are symmetrically arranged with the wire drawing die 26 as the symmetry point. The wire pay-off shaft 21 is located directly below one of the round pipes of the oil dripping pipe 25; As Figure 1 and Figure 4 shown, a slider 23 is fixedly connected to the same side of the first steering shaft 22 and the second steering shaft 27 close to the support plate 10. The slider 23 slides in the square chute. A bayonet is opened on the side of the square chute away from the oil sump 11. A nail-shaped hole is opened inside the slider 23. A nail-shaped column is fixedly connected to one end of the clamping block 28 close to the slider 23. A spring 29 is fixedly arranged between the nail-shaped column and the nail-shaped hole. The clamping block 28 is elastically connected to the slider 23 through the spring 29. The clamping block 28 slides in the nail-shaped hole through the nail-shaped column, and the clamping block 28 is clamped in the bayonet.

[0033] The working principle is as follows. Multiple nozzles are provided on the curved surface part of the drip oil pipe 25 close to the wire pay-off reel 21, the first steering shaft 22, and the second steering shaft 27. The nozzles correspond to the positions of the annular openings. During use, first adjust the positions of the first steering shaft 22 and the second steering shaft 27 according to the length of the silver-plated wire. Pull the clamping block 28 and the slider 23 apart, and move the positions of the first steering shaft 22 and the second steering shaft 27 to make the slider 23 slide in the square chute. When the first steering shaft 22 and the second steering shaft 27 are in the appropriate positions, release the clamping block 28. The clamping block 28 resets under the action of the spring 29, and then the clamping block 28 is clamped in the corresponding bayonet. At this time, select the appropriate annular opening of the wire pay-off reel 21 according to the diameter of the silver-plated wire, wind the silver-plated wire around the corresponding annular opening of the wire pay-off reel 21, then around the corresponding annular opening of the second steering shaft 27, pass the silver-plated wire through the wire drawing die 26, and then around the first steering shaft 22. Put the winding roller for wire winding on the take-up reel 13, and then wind the drawn silver-plated wire around the winding roller. Start the rotary motor 12 connected to the take-up reel 13, and the take-up reel 13 starts to rotate, thereby driving the silver-plated wire to slide on the wire pay-off reel 21, the first steering shaft 22, and the second steering shaft 27, so as to help wind and take up the silver-plated wire after wire drawing on the winding roller. In this process, an external lubricating oil is connected to the oil delivery hose 24. Through the delivery of the oil delivery hose 24, the lubricating oil reaches the drip oil pipe 25, and the lubricating oil is ejected through several nozzles arranged at the bottom of the drip oil pipe 25, so as to lubricate the silver-plated wire.

[0034] As Figure 1 and Figure 2 shown, a rotary motor 12 is fixedly arranged on the back side of the support plate 10 away from the oil sump 11 through a bracket. A circular hole is opened inside the support plate 10, and the circular hole is arranged opposite to the rotary motor 12. A take-up reel 13 is rotatably connected in the circular hole through a bearing. The output end of the rotary motor 12 is connected to the end face of the take-up reel 13; As Figure 3 shown, a circular through-hole and two chutes of different sizes are opened inside the fixed plate 14. A shaft column is rotatably connected in the circular through-hole through a bearing. Rotation holes are opened at both ends of the crank 17, and short columns are fixedly connected to both ends of the connecting rod 19. One end of the shaft column is rotatably connected to one end of the crank 17. A uniform speed motor 16 is fixedly arranged on the side of the fixed plate 14 away from the fixed rack 15 through a bracket. The output end of the uniform speed motor 16 is connected to the other end of the shaft column. The other rotation hole of the crank 17 is rotatably connected to one rotation column of the connecting rod 19. The other rotation column of the connecting rod 19 is rotatably connected to the center of the gear 18. A T-shaped sliding column is fixedly arranged on the side of the gear 18 away from the connecting rod 19, and the T-shaped sliding column slides in the small chute; As Figure 3As shown, the fixed rack 15 is fixedly arranged directly below the small slideway of the fixed plate 14. The moving block 20 is composed of a T-shaped slider, a rack plate, a circular column, and a square column. The T-shaped slider slides within the large slideway. Both the rack plate and the fixed rack 15 are in meshing transmission with the same gear 18. The circular column is located above the square column, and the square column is located above the top surface of the rack plate.

[0035] The working principle is as follows. When in use, one end of the silver-plated wire is passed through the center of the circular column, and then the silver-plated wire is wound around the winding roller for wire collection. The uniform speed motor 16 is started. The rotation of the shaft column drives the rotation of the crank 17. The crank 17 pulls the movement of the connecting rod 19. While the connecting rod 19 drives the gear 18 to slide within the small slideway, the gear 18 will simultaneously be in meshing transmission with the fixed rack 15. At this time, the transmission of the gear will push the meshing of the rack plate arranged below the moving block 20, thereby pushing the T-shaped slider to slide within the large slideway. When the gear 18 moves towards the shaft column direction, the rack plate will move towards the shaft column direction along with the direction of the gear 18, moving back and forth in this way. At this time, due to the rotation of the wire collection roller 13, the silver-plated wire is wound around the winding roller. At this time, the silver-plated wire is uniformly wound around the winding roller to complete wire collection under the drive of the circular column.
