Abstract
Description
Technical Field
[0001] This invention relates to the field of copper wire drawing technology, and more specifically to a continuous copper wire drawing device. Background Technology
[0002] Copper wire is a type of copper material. Copper wire can be used in industries such as power transmission, electronics, communication and data networks, and industrial manufacturing. A drawing device is a device composed of a roller drum and drawing dies. The roller drum passes the thicker copper wire through the drawing dies multiple times, making the copper wire thinner.
[0003] Chinese patent CN220387488U discloses a high-speed water tank wire drawing machine, relating to the field of wire drawing equipment technology. The prior art includes a machine body, with a first drawing roller, a second drawing roller, and a third drawing roller connected via transmission to the side of the water tank near the drive housing. The first drawing roller includes a drive gear, the end face of which is fixed to the drawing roller body via a connecting rod. A winding groove is formed on the outer side of the drawing roller body, and an extending water hole is formed inside the winding groove. A connecting water pipe and a drain water pipe are movably connected to the drive gear, the connecting rod, and the inside of the drawing roller body. The non-connecting end of the connecting water pipe is fixed to and communicates with the drain water pipe, which has a drain outlet. The prior art utilizes the one-to-one correspondence between the water holes and the winding groove, as well as the fixed-distance openings of the drain outlets on the drain water pipe, to allow water to flow out in a rushing manner onto the drawn wire, reducing water usage. Furthermore, the staggered arrangement between the rollers avoids obstruction between the drawing rollers, facilitating the wire drawing operation.
[0004] However, during use, a lot of oil stains will be generated in the groove of the turret drum. These oil stains will not only cause the wire to sway left and right in the groove of the turret drum, affecting the stability during wire drawing, but also cause the wire to break due to the swaying of the wire in the existing technology. Summary of the Invention
[0005] The purpose of this invention is to address the problems existing in the background art by proposing a continuous copper wire drawing device.
[0006] The technical solution of this invention: A continuous copper wire drawing device includes a liquid storage tank, a wire drawing die, a tower wheel type drum, and a chute; the wire drawing die is installed in the middle of the liquid storage tank, and the tower wheel type drum is installed in the inner cavity of the liquid storage tank; a support telescopic rod is opened on the tower wheel type drum, and the device further includes: a buffer mechanism installed on the liquid storage tank; a cleaning mechanism installed on the drive end of the buffer mechanism; the cleaning mechanism includes a grinding component, a smoothing component, a pushing component, and a grinding cylinder; the grinding cylinder is installed on the drive end of the buffer mechanism; the grinding component is installed at the bottom inside the grinding cylinder and is used for cleaning the chute; the smoothing component is installed at the top inside the grinding cylinder and is used for limiting the wire; the pushing component is installed inside the smoothing component and is used for pushing the grinding component; the buffer mechanism pushes the grinding cylinder towards the chute, the smoothing component contacts the wire, the grinding component contacts the inner wall of the chute, the grinding component grinds the chute, and the smoothing component limits the wire.
[0007] Preferably, the grinding assembly includes an elastic element two and a grinding element; the two ends of the elastic element two are respectively connected to the inner wall of the grinding cylinder and the grinding element; the grinding element is slidably connected to the bottom end of the middle part of the grinding cylinder.
[0008] Preferably, the smoothing component includes an elastic element three and a smoothing element; the two ends of the elastic element three are respectively connected to the inner wall of the grinding cylinder and the smoothing element; the smoothing element is slidably connected to the top end of the middle part of the grinding cylinder.
[0009] Preferably, the pushing assembly includes an elastic element four, an inclined block, a blocking plate, a pushing plate, an elastic element five, and a rolling wheel; the two ends of the elastic element four are respectively connected to the inner cavity of the smooth part and the inclined block; the top of the inclined block is connected to the blocking plate; the blocking plate is sleeved in the inner cavity of the smooth part; the pushing plate is installed at the bottom of the inclined block; the two ends of the elastic element five are respectively connected to the inner cavity of the grinding cylinder and the rolling wheel, and the rolling wheel limits the inclined block.
[0010] Preferably, the buffer mechanism includes a drive component and a buffer component; the drive component is installed outside the liquid storage tank, and the buffer component is installed at the drive end of the drive component.
[0011] Preferably, the drive assembly includes a drive device and a mounting plate; the drive device is installed on the outside of the liquid storage tank, the mounting plate is installed on the output end of the drive device, and the buffer assembly is installed on the mounting plate.
[0012] Preferably, the buffer assembly includes a piston cylinder, a micro gas delivery device, a piston plate, an elastic element, a linkage plate, a connecting plate, and a support telescopic rod; the piston cylinder is mounted on the mounting plate, and the micro gas delivery device is mounted on the piston cylinder; the piston plate is sleeved inside the piston cylinder; the two ends of the elastic element are respectively connected to the piston plate and the linkage plate; the connecting plate is mounted on the linkage plate; the connecting plate is connected to the grinding cylinder; the two ends of the support telescopic rod are respectively connected to the inner wall of the liquid storage tank and the connecting plate.
[0013] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: After the copper wire is fed into the chute, the drive device is started to move the grinding cylinder towards the chute. The grinding cylinder and grinding parts will fit against the inner wall of the chute. At this time, the drive device drives the grinding cylinder to continue to squeeze towards the chute. When the elastic element is compressed to its minimum length, the drive device stops moving. The micro air supply device discharges the air from the inner cavity of the piston cylinder. At this time, the elasticity of the elastic element drives the piston plate to move towards the micro air supply device, thereby allowing the elastic element to unfold. This allows the grinding cylinder to be naturally fitted against the inner wall of the chute without being subjected to external force. This avoids the drive device from making the grinding cylinder fit too tightly against the inner cavity of the chute, which would cause the grinding cylinder and grinding parts to over-grind the chute, resulting in a rough inner wall of the chute.
[0014] Next, the wire is pressed and limited by the grinding and smoothing parts. The thicker the wire, the more the smoothing parts are pushed. The smoothing parts that are not pushed limit the wire from the side. At the same time, when the smoothing parts are pushed, the inclined block moves towards the elastic part five. The elastic part five moves to the blocking plate. At this time, the inclined block loses the limitation of the elastic part five. The elasticity of the elastic part four drives the push plate to push the grinding part towards the elastic part three a distance. At this time, only the smoothing part is in contact with the surface of the wire, while the grinding part is separated from the wire. This achieves the grinding and removal of oil stains and other contaminants from the inner wall of the groove by the grinding cylinder and grinding parts. The smoothing parts limit the wire, minimizing the shaking of the wire and preventing the wire from being ground. Attached Figure Description

[0016] Example 1, as Figures 1-7 As shown, the present invention proposes a continuous copper wire drawing device, comprising a liquid storage tank 1, a drawing die 2, a roller drum 3, and a chute 9; the drawing die 2 is installed in the middle of the liquid storage tank 1, and the roller drum 3 is installed in the inner cavity of the liquid storage tank 1; a support telescopic rod 25 is provided on the roller drum 3, and the device further comprises: a buffer mechanism installed on the liquid storage tank 1; a cleaning mechanism installed on the drive end of the buffer mechanism; the cleaning mechanism includes a grinding component, a smoothing component, a pushing component, and a grinding cylinder 14; the grinding cylinder 14 is installed on the drive end of the buffer mechanism; the grinding component is installed at the bottom inside the grinding cylinder 14 and is used in the chute 9. The internal cleaning process is as follows: a smoothing component is installed at the top inside the grinding cylinder 14 and is used to limit the wire; a pushing component is installed inside the smoothing component and is used to push the grinding component; a buffer mechanism pushes the grinding cylinder 14 towards the slide groove 9, the smoothing component contacts the wire, the grinding component contacts the inner wall of the slide groove 9, the grinding component grinds the inside of the slide groove 9, and the smoothing component limits the wire; limiters 4 are installed on both sides of the liquid storage tank 1, the copper wire passes through one of the limiters 4, and then reciprocates in the slide groove 9 of the tower wheel drum 3 and the wire drawing die 2; the inner cavity of the liquid storage tank 1 is filled with coolant, and the bottom of the tower wheel drum 3 is located in the coolant.
[0017] The grinding assembly includes an elastic element 15 and a grinding element 16. The two ends of the elastic element 15 are respectively connected to the inner wall of the grinding cylinder 14 and the grinding element 16. The grinding element 16 is slidably connected to the bottom end of the middle part of the grinding cylinder 14. The grinding element 16 fits against the inner wall of the groove 9, thereby removing impurities and oil stains from the inner wall of the groove 9.
[0018] The smoothing component includes an elastic element 17 and a smoothing element 18. The two ends of the elastic element 17 are respectively connected to the inner wall of the grinding cylinder 14 and the smoothing element 18. The smoothing element 18 is slidably connected to the top of the middle part of the grinding cylinder 14. The smoothing element 18 is in contact with the copper wire. Because the surface of the smoothing element 18 is smooth, the wire will not be affected when it moves in the inner cavity of the groove 9.
[0019] The pushing assembly includes an elastic element 19, an inclined block 20, a blocking plate 21, a pushing plate 22, an elastic element 23, and a rolling wheel 24. The two ends of the elastic element 19 are connected to the inner cavity of the smooth part 18 and the inclined block 20, respectively. The top of the inclined block 20 is connected to the blocking plate 21. The blocking plate 21 is fitted into the inner cavity of the smooth part 18. The pushing plate 22 is installed at the bottom of the inclined block 20. The two ends of the elastic element 23 are connected to the inner cavity of the grinding cylinder 14 and the rolling wheel 24, respectively. The rolling wheel 24 limits the movement of the inclined block 20. When the smooth part 18 is pushed towards the groove 9 and contacts the wire, the smooth part 18 is pushed towards the grinding cylinder 14. At this time, the inclined block 20 moves towards the rolling wheel 24, causing the elastic element 23 to rise along the inclined surface of the inclined block 20. When the elastic element 23 moves onto the blocking plate 21, the inclined block 20... The surface block 20 is no longer limited by the rolling wheel 24, so the elasticity of the elastic element 4 19 drives the inclined block 20 and the push plate 22 to push the grinding part 16 a certain distance towards the elastic element 2 15, so that only the smooth part 18 contacts the wire; the moving distance of the inclined block 20 is fixed. When the driving device 5 drives the grinding cylinder 14 to leave the slide 9 and the smooth part 18 and the grinding part 16 are reset, the smooth part 18 drives the top of the inclined block 20 to move below the rolling wheel 24. At this time, since the rolling wheel 24 is located at the top of the inclined surface of the inclined block 20, the rolling wheel 24 descends along the inclined surface of the inclined block 20, thereby pushing the inclined block 20 towards the elastic element 4 19. At this time, the push plate 22 also moves towards the inclined block 20, so that the grinding part 16 moves towards the smooth part 18 to reset.
[0020] Example 2, as Figures 1-6 As shown, the copper wire continuous drawing device proposed in this invention, compared with Embodiment 1, has a buffer mechanism that includes a driving component and a buffer component; the driving component is installed outside the liquid storage tank 1, and the buffer component is installed at the driving end of the driving component.
[0021] The drive assembly includes a drive device 5 and a mounting plate 6; the drive device 5 is installed on the outside of the liquid storage tank 1, the mounting plate 6 is installed on the output end of the drive device 5, and the buffer assembly is installed on the mounting plate 6; when the drive device 5 is started, it drives the mounting plate 6 to move towards the slide 9, so that the grinding cylinder 14 fits against the inner wall of the slide 9.
[0022] The buffer assembly includes a piston cylinder 7, a micro gas delivery device 8, a piston plate 10, an elastic element 11, a linkage plate 12, a connecting plate 13, and a support telescopic rod 25. The piston cylinder 7 is mounted on the mounting plate 6, and the micro gas delivery device 8 is mounted on the piston cylinder 7. The piston plate 10 is sleeved inside the piston cylinder 7. The two ends of the elastic element 11 are respectively connected to the piston plate 10 and the linkage plate 12. The connecting plate 13 is mounted on the linkage plate 12 and is connected to the grinding cylinder 14. The two ends of the support telescopic rod 25 are respectively connected to the inner wall of the liquid storage tank 1 and the connecting plate 13. When the grinding cylinder 14 is driven by the driving device 5 and pressed against the inner wall of the slide groove 9, it may cause the grinding cylinder 14 to fit too closely to the inner wall of the slide groove 9, thereby causing the slide groove 9 to rotate and be excessively ground by the grinding cylinder 14. In the initial state, the inner cavity of the piston cylinder 7 is... The miniature gas delivery device 8 is filled with high-pressure gas. When the grinding cylinder 14 is pressed against the inner wall of the slide groove 9, the elastic element 11 is compressed. At this time, the miniature gas delivery device 8 is activated to release the air in the inner cavity of the piston cylinder 7. The elasticity of the elastic element 11 drives the piston plate 10 to move towards the miniature gas delivery device 8. The inner cavity of the piston cylinder 7 can retain some air. After the elastic element 11 is extended, the piston plate 10 maintains stability. Alternatively, the piston plate 10 can be directly attached to the inner wall of the piston cylinder 7. The miniature gas delivery device 8 is installed on the side of the piston cylinder 7. The elastic element 11 is composed of a spring and a pressure sensor. The elastic elements 15, 17, 19, and 23 are all composed of a spring and a telescopic rod. The linkage plate 12 is stably supported by the telescopic rod 25.
[0023] In summary, in this application, the inner cavity of the liquid storage tank 1 is filled with coolant. Then, the wire passes through one of the limiting members 4 into the liquid storage tank 1, is fitted into the inner groove 9 of one of the tower wheel type drums 3, then passes through the drawing die 2, and then is fitted into the groove 9 of another tower wheel type drum 3. This process is repeated so that the wire passes through the drawing die 2 multiple times and is discharged through another limiting member 4. Then, the drive device 5 is started to drive the grinding cylinder 14 to move towards the groove 9, so that the grinding cylinder 14 fits against the inner wall of the groove 9. At this time, the elastic element 11 is compressed to its shortest length. Then, the drive device 5 stops operating, and then the micro air supply device 8 is started to discharge the air in the piston cylinder 7, so that the elastic element 11 releases its elasticity and is in a stretched state, so that the grinding cylinder 14 naturally fits against the inner wall of the groove 9.
[0024] When the smoothing part 18 and the grinding part 16 come into contact with the wire in the groove 9, the grinding part 16 and the smoothing part 18 are pushed into the grinding cylinder 14, causing the rolling wheel 24 to rise along the inclined surface of the inclined block 20 onto the baffle plate 21. This causes the inclined block 20 to lose the restraint of the rolling wheel 24. Subsequently, the elasticity of the elastic element 4 19 drives the grinding part 16 to move a certain distance towards the elastic element 3 17, thus preventing the grinding part 16 from contacting the wire. Afterward, the grinding part 16 and the smoothing part 18 restrain the wire from the side, and the grinding part 16 and the smoothing part 18 then proceed with the process. The grinding cylinder 14 and the grinding piece 16 grind the inner wall of the slide groove 9, and the grinding piece 16 and the smoothing piece 18 fix the wire, reducing the swaying amplitude of the wire in the slide groove 9 and improving stability. Then the driving device 5 drives the grinding cylinder 14 to separate and reset from the slide groove 9. At this time, the inclined block 20 moves back to below the elastic piece 23. Then the elasticity of the elastic piece 23 drives the rolling wheel 24 to move towards the inclined block 20, thereby pushing the inclined block 20 towards the elastic piece 19 along the inclined surface of the inclined block 20, thereby resetting the grinding piece 16.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
