Description

Technical Field

[0001] This invention relates to the field of copper body processing technology, specifically to a wire drawing device for processing copper conductors for high-speed communication. Background Technology

[0002] In the field of high-speed communications, copper conductor processing is crucial. At the outset, high-purity copper must be selected and subjected to smelting and purification processes to ensure the purity of the substrate. Subsequently, the copper is drawn into fine wires of the required diameter using a wire drawing process. This process requires precise control of the drawing die parameters and drawing speed to ensure a smooth surface and accurate dimensions of the copper wire.

[0003] In the typical process of processing copper conductors for communication, a wire drawing device is required to stretch the copper wire to the required size.

[0004] Depending on the required dimensions of the stretched copper conductor, thinner conductors require more passes through the drawing die. Multiple drawing passes effectively control the degree of deformation each time, reducing internal stress. During multiple drawing passes, as the copper conductor becomes thinner, its linear velocity changes. According to the law of constant volume, the cross-sectional area of ​​the copper conductor decreases, its length increases accordingly, and the linear velocity also increases. To ensure stable tension during winding, the diameter of the winding roller needs to be adjusted. If the roller diameter does not increase with the thinning of the copper conductor, uneven layering may occur during winding. Gradually increasing the roller diameter allows the linear velocity of the copper conductor to be coordinated with the drawing speed during winding, preventing the copper conductor from being stretched due to excessive tension. Problems such as breakage or insufficient tension leading to loose strands can occur. Furthermore, during the winding process after copper wire drawing, it's crucial to ensure equal linear speeds at the input and output ends. If the radius of the large spool is larger than the small spool, when their rotational speeds are the same, the winding speed on the large spool will be greater than the winding speed on the small spool. This can cause the wire to accumulate on the small spool, potentially leading to knots, tangles, or even deformation or breakage. Conversely, if the radius of the small spool is larger than the large spool, the winding speed on the small spool will be greater than the unwinding speed on the large spool, resulting in a very tight wire. Prolonged exposure to this tension can also easily cause the wire to break. This makes it difficult to balance the radial dimensions and angular velocities in different drawing modes (multi-parallel and single-parallel), causing inconvenience in use.

[0005] In view of this, we propose a wire drawing device for processing copper conductors for high-speed communication. Summary of the Invention

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1 to 20 The present invention provides a technical solution: a wire drawing device for processing copper conductors for high-speed communication, comprising a device base 1, a reduction gearbox 2 fixedly connected to the top surface of the device base 1, a working box 11 fixedly connected to the top surface of the device base 1, a cooling nozzle 12 fixedly connected to the inner surface of the working box 11, a wire drawing die head 13 fixedly connected to the inner surface of the working box 11, a drive motor 21 fixedly connected to the input end of the reduction gearbox 2, a transmission sprocket 22 fixedly connected to the output end of the reduction gearbox 2, a transmission chain 221 sleeved on the outer surface of the transmission sprocket 22, and an output shaft 23 fixedly connected to the outer surface of the transmission sprocket 22.

[0044] The drive motor 21 adjusts the speed and torque through the reduction gearbox 2, and drives the two output shafts 23 to rotate through the transmission sprocket 22 and the transmission chain 221. The wire drawing die head 13 is used for wire drawing and sprays coolant through the cooling nozzle 12 during the operation.

[0045] An adjustable winding disc 3 is provided on the outer surface of the output shaft 23, and an adjustment control lever 4 is provided on the bottom surface of the adjustable winding disc 3. A linear speed adjustment shaft 5 is provided on the outer surface of the device base 1, and a winding post 6 is provided at one end of the linear speed adjustment shaft 5.

[0046] There are two transmission sprockets 22 and two output shafts 23, with the output shaft 23 extending through to the inner surface of the working box 11.

[0047] The adjustable winding reel 3 includes a reel base 31, which is fixedly connected to the outer surface of the output shaft 23. A reel rib 311 is fixedly connected to the outer surface of the reel base 31, and a straight groove 312 is formed on the outer surface of the reel rib 311. An outer baffle 32 is fixedly connected to the outer surface of the output shaft 23. An expansion shell 33 is slidably connected to the outer surface of the reel base 31, and a positioning post 331 is fixedly connected to the outer surface of the expansion shell 33. The inner surface of the expansion shell 33 is slidably connected to the outer surface of the expansion shell 33. An inner connecting plate 332 is connected to the outer surface of the disk base 31, and an inner turntable 34 is rotatably connected to it. An arc-shaped groove 341 is opened on the outer surface of the inner turntable 34, and a locking block groove 342 is opened on the outer surface of the inner turntable 34. An outer rotating ring 35 is fixedly connected to the outer surface of the inner turntable 34, and an adjustment groove 351 is opened on the outer surface of the outer rotating ring 35. A ring locking block 36 is slidably connected to the outer surface of the disk rib plate 311, and a locking block spring 361 is fixedly connected to the outer surface of the ring locking block 36.

[0048] With the adjustable winding discs 3, during use, each output shaft 23 is equipped with six sets of adjustable winding discs 3. The output shaft 23 drives all the adjustable winding discs 3 to rotate, and the copper conductor passes through the middle drawing die head 13. The difference between single and multiple drawing is that the diameter of the winding roller needs to be gradually increased to match the linear speed for multiple drawing. The copper wire wound on the adjustable winding discs 3 will wrap around the surface of the expansion shell 33. The positioning post 331 on the expansion shell 33 contacts both the straight groove 312 and the arc groove 341, so that it can only move in a straight line in the straight groove 312. By rotating the arc groove 341, the positioning post 331 is moved to move on the straight groove 312. When moving outward, the expansion shell 33 moves away from the center to increase the radial dimension, and the distance between the expansion shells 33 increases. This is filled by the middle inner connecting plate 332, so that the radial dimension of the copper wire wound on the adjustable winding discs 3 can be changed.

[0049] The ring block 36 passes through the disc base 31 and is locked in the locking slot 342 of the inner turntable 34. There are six locking slots 342, which makes the disc base 31 and the inner turntable 34 have six stages, realizing stepped adjustment. When the locking spring 361 is inserted into the locking slot 342, the disc base 31 and the inner turntable 34 are connected, and the inner turntable 34 cannot rotate on the disc base 31, so that the position of the arc groove 341 is locked and the radial dimension of the expansion shell 33 is fixed. After the ring block 36 is lifted, the outer ring 35 is turned to drive the inner turntable 34 to rotate, thereby controlling the radial dimension of the adjustable winding disc 3 winding the copper wire, and locking it after adjustment. The adjustable winding disc 3 rotates with the output shaft 23 and pulls the copper wire through the drawing die head 13 in sequence.

[0050] The adjustable winding discs 3 are six in number on each output shaft 23 and are evenly distributed. There are six straight grooves 312, six expansion shells 33, and six arc grooves 341, which are distributed in a ring on the outer surface of the disc rib plate 311. The two sides of the inner connecting plate 332 are slidably connected to the inner surface of the expansion shell 33. The positioning pins 331 are slidably connected to the inner surfaces of the straight grooves 312 and the arc grooves 341. There are six locking slots 342, which are slidably connected to the ring locking blocks 36. The ring locking blocks 36 penetrate the disc base 31 and are slidably connected to its inner wall. The ring locking blocks 36 are made of iron. The two ends of the locking springs 361 are fixedly connected to the ring locking blocks 36 and the disc rib plate 311, respectively.

[0051] Based on the different internal radial dimensions of the adjustable winding discs 3, there are six stages of stepped adjustment between the disc base 31 and the inner turntable 34. These six stages are labeled as one, two, three, four, five, and six. When the required size of the copper wire is small and six wire drawing steps are required, the six adjustable winding discs 3 on each side are adjusted to one, two, three, four, five, and six, with the radial dimensions increasing sequentially. At this time, the copper wire passes through six drawing dies 13 in sequence and is successively fitted onto the adjustable winding discs 3 with gradually increasing radial dimensions. If the required size of the copper wire is large and six wire drawing steps are not required, such as... With just one wire drawing operation, the six adjustable winding reels 3 are adjusted to a uniform radial size, allowing six groups of copper wires to be drawn simultaneously in parallel. If two wire drawing operations are required to achieve the desired size, then each pair of adjustable winding reels 3 is grouped together and adjusted to the required size, such as 1-2-1-2-1-2, 5-6-5-6-5-6-5, etc., allowing three groups of copper wires to be drawn simultaneously. Similarly, three wire drawing operations can be performed in two parallel operations, such as 1-2-3-1-2-3 or 2-3-4-2-3-4, achieving the effect of adjusting the parallel operation according to the required number of stretching operations for the copper wires.

[0052] The adjustment control lever 4 includes a rotating handle 41, which is rotatably connected to the inner surface of the work box 11. Six equally spaced magnetic blocks 411 are fixedly connected to the outer surface of the rotating handle 41. A lifting cylinder 42 is fixedly connected to the top surface of the device base 1. A bushing 421 is fixedly connected to the output end of the lifting cylinder 42. A control shaft 43 is rotatably connected to the inner surface of the bushing 421. A meshing protrusion 431 is fixedly connected to the outer surface of the control shaft 43. Six equally spaced driven discs 44 are slidably connected to the outer surface of the control shaft 43. A toggle lever 441 is fixedly connected to one end of the driven disc 44, and a toggle groove 442 is fixedly connected to the other end of the driven disc 44. A meshing groove 443 is provided on the inner surface of the driven disc 44.

[0053] The magnetic block 411 is magnetically connected to the ring block 36, the control shaft 43 extends through to the inner surface of the working box 11, and the driven plate 44 engages with the adjustment groove 351;

[0054] By adjusting the settings of the control lever 4, during use, multiple magnetic blocks 411 are installed on the rotating handle 41, all located on top of the ring block 36. Rotating the handle 41 causes the magnetic blocks 411 to face upwards or downwards. When facing downwards, the ring block 36 is lifted, and the ring block 36 no longer holds the inner turntable 34, allowing the inner turntable 34 to rotate freely. In the initial state, the driven disk 44 on the control shaft 43 is away from the adjustment groove 351. The control shaft 43 is lifted by the lifting cylinders 42 on both sides, and the driven disk 44 engages with the adjustment groove 351. At this time, depending on the different engagement states of the control shaft 43 and the driven disk 44, different numbers of driven disks 44 are driven to rotate. The driven disk 44 drives the outer rotating ring 35 to rotate through the adjustment groove 351. For every rotation of the driven disk 44, the outer rotating ring 35 rotates and aligns the ring block 36 with the next or previous locking block groove 342, achieving the effect of polarized adjustment.

[0055] Six driven discs 44 are fitted on the control shaft 43, each corresponding to one of the six adjustable winding discs 3. At the same time, the control shaft 43 has a different number of engaging protrusions 431 for engaging with the driven discs 44. Only when engaged can the control shaft 43 rotate to drive the driven discs 44 to rotate. When not engaged, the driven discs 44 are stuck in the adjustment grooves 351 and cannot rotate. After the driven disc 44 rotates one revolution, the actuating rod 441 will contact the actuating groove 442 of the next driven disc 44, so that the previous driven disc 44 drives the next driven disc 44 to rotate. The same applies to subsequent driven discs 44, but they must first rotate one revolution before they can drive the subsequent driven disc 44 to rotate, so that the rotation of the two driven discs 44 is one revolution apart.

[0056] Depending on the length of the control shaft 43, there are four states, corresponding to the first, second, third, and sixth parallel modes of the adjustable winding disc 3. The number of engaged driven discs 44 varies depending on the engagement protrusion 431. In the first parallel mode, only the first driven disc 44 is engaged. After this driven disc 44 rotates five times, the subsequent driven discs 44 rotate four, three, two, one, and zero times in sequence, so that the adjustable winding disc 3 is in the first, second, third, fourth, fifth, and sixth modes, with the radial dimension gradually increasing to allow the copper wire to be drawn six times. In the second parallel mode, the first and fourth driven discs 44 are engaged, following the control. After shaft 43 rotates two revolutions, driven discs 2 and 5 rotate one revolution, and driven discs 3 and 6 rotate zero revolutions. The adjustable winding disc 3 is in a 1-2-3-1-2-3 mode, which can perform two parallel operations and three wire drawing operations respectively. The same applies to three parallel operations. Driven discs 1, 3, and 5 drive driven discs 2, 4, and 6 to rotate. The adjustable winding disc 3 is in a 1-2-1-2-1-2 mode. In the six parallel operation mode, the meshing protrusion 431 meshes with all driven discs 44, driving all driven discs 44 to rotate. This allows the radial dimension of the adjustable winding disc 3 to be adjusted synchronously according to the required parallel operation.

[0057] The linear speed regulating shaft 5 includes an input pulley 51, which is fixedly connected to the outer surface of the output shaft 23. A first hinge arm 52 is rotatably connected to the other end of the input pulley 51. A hinge seat 53 is hinged to one end of the first hinge arm 52. An intermediate pulley 531 is rotatably connected to the outer surface of the hinge seat 53. A second hinge arm 54 is hinged to the other end of the hinge seat 53. An output pulley 55 is rotatably connected to the outer surface of the second hinge arm 54. One end of the output pulley 55 is fixed. A drive wheel 56 is connected, and a wheel cylinder 561 is slidably connected to the outer surface of the drive wheel 56. A mounting base 57 is fixedly connected to the outer surface of the device base 1. Six matching columns 571 are slidably connected to the inner surface of the mounting base 57. A driven wheel 58 is engaged with the bottom surface of the drive wheel 56. A driven shaft 581 is slidably connected to the inner surface of the driven wheel 58. A return spring 582 is sleeved on the outer surface of the driven shaft 581. An outer bracket 59 is fixedly connected to the outer surface of the mounting base 57.

[0058] The input pulley 51 and the intermediate pulley 531 form a belt drive, the intermediate pulley 531 and the output pulley 55 form a belt drive, the driving pulley 56 passes through the second hinge arm 54 and is fixedly connected to the output pulley 55, the matching column 571 passes through the driving pulley 56 and is slidably connected to its inner wall, the wheel cylinder 561 is fixedly connected to the outer bracket 59, the driven shaft 581 is rotatably connected to the outer bracket 59, there are two driven pulleys 58, and both ends of the return spring 582 are in contact with the driven pulleys 58, the driving pulley 56 drives the driven pulleys 58 to rotate;

[0059] By setting the linear speed adjustment shaft 5, during use, after the radial dimension of the adjustable winding disc 3 is adjusted, the copper wire passes through the adjustable winding disc 3 and the drawing die head 13 in sequence, and is finally sleeved on the matching post 571. There are six matching posts 571. According to the different radial dimensions of the adjustable winding disc 3, the height of the copper wire after it extends is different, and it is sleeved on the matching post 571 of the corresponding height. The matching post 571 is then pushed out. One end of the drive wheel 56 is connected to the matching post 571 of the corresponding height. At the same time, the wheel cylinder 561 rises on the other side to support the drive wheel 56. While the output shaft 23 drives the adjustable winding disc 3 to rotate, it will also send out a part of the power to drive the drive wheel 56 to rotate. According to the different radial dimensions of the adjustable winding disc 3, the height of the drive wheel 56 is different, and the speed of the driven wheel 58 is different, thereby matching the linear speed of the adjustable winding disc 3 and the winding post 6, ensuring that the copper wire is stably wound from the adjustable winding disc 3 to the winding post 6.

[0060] The output shaft 23 first directly drives the input pulley 51 to rotate, the input pulley 51 drives the intermediate pulley 531 to rotate, the intermediate pulley 531 then drives the output pulley 55 to rotate, and finally drives the drive pulley 56 to rotate. The input pulley 51 and the output pulley 55 are respectively mounted on the first hinge arm 52 and the second hinge arm 54. The two hinge arms are hinged together. Due to the different rotation angles between them, the distance between the input pulley 51 and the output pulley 55 is also different. However, the distance from the input pulley 51 and the output pulley 55 to the intermediate pulley 531 remains constant, so that the distance between the input pulley 51 and the output pulley 55 can be adjusted but still maintain synchronous rotation, thereby adapting to different heights of the drive pulley 56.

[0061] When the driving wheel 56 rotates, it drives the driven wheel 58 at the bottom to rotate. The surface of the driving wheel 56 is arc-shaped and contacts the driven wheel 58. When the driving wheel 56 descends, it presses the driven wheel 58 inward, and the contact point also changes. A vertical tangent is made at the contact point, which can be regarded as the pitch circle of the driving wheel 56 during meshing. The closer the tangent is to the apex of the arc surface of the driving wheel 56, the shorter its circumference. The smaller the pitch circle of the driving wheel 56, the smaller the transmission ratio, and the faster the driven wheel 58 moves. When the driving wheel 56 rises, the contact point between the driven wheel 58 and the driving wheel 56 moves outward under the action of the return spring 582. The transmission ratio increases and the speed of the driven wheel 58 decreases. In this way, the transmission speed of the winding column 6 can be adjusted according to the radial dimension of the adjustable winding disc 3, so that the linear speed between the adjustable winding disc 3 and the winding column 6 is always equal. The radial dimension of the adjustable winding disc 3 changes but the speed remains unchanged, and the angular velocity of the winding column 6 changes accordingly but the radial dimension remains unchanged, that is, R3ω3=R6ω6.

[0062] The winding post 6 includes a fixed rotating shaft 61, which is fixedly connected to the driven wheel 58. A movable rotating shaft 62 is slidably connected to the inner surface of the fixed rotating shaft 61. A winding shaft 621 is fixedly connected to one end of the movable rotating shaft 62. A push-pull seat 63 is slidably connected to the outer surface of the winding shaft 621. A contact ball protrusion 631 is fixedly connected to the inner surface of the push-pull seat 63. A winding pulley 64 is rotatably connected to the inner surface of the outer bracket 59. A cylindrical cam 641 is fixedly connected to one end of the winding pulley 64.

[0063] The contact ball cam 631 meshes with the cam groove on the outer surface of the cylindrical cam 641. The cam groove on the outer surface of the cylindrical cam 641 is double helix. The winding pulley 64 is connected to the driven shaft 581. The cylindrical cam 641 passes through the push-pull seat 63.

[0064] With the setting of the winding post 6, during use, the driven wheel 58 drives the fixed rotating shaft 61 to rotate. The fixed rotating shaft 61 is in a fixed position. The fixed rotating shaft 61 drives the movable rotating shaft 62 to rotate. The movable rotating shaft 62 is connected to the fixed rotating shaft 61 through a groove. It can move on the fixed rotating shaft 61 and rotate synchronously. The winding shaft 621 inherits the movable and synchronous rotation effect of the movable rotating shaft 62 and is used for winding. Part of the power of the driven wheel 58 drives the cylindrical cam 641 to rotate through the winding pulley 64. The cylindrical cam 641 is connected to the push-pull seat 63. A cam structure is formed by the contact ball protrusion 631. The cam groove is a double helix. When it rotates to one end, it will enter the other helical groove to achieve reverse movement, so that the push-pull seat 63 moves back and forth. In this way, when winding copper wire, the copper wire can be evenly wound on the surface of the winding shaft 621 to prevent it from piling up in the same position.

[0065] In this embodiment, as Figure 1 , Figure 2 As shown, each component is installed inside the device base 1 and the work box 11;

[0066] In this embodiment, as Figure 3 As shown, the drive motor 21 drives the adjustable winding disc 3 to rotate by adjusting the speed and torque through the reduction gearbox 2;

[0067] In this embodiment, as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the adjustable winding disc 3 moves the expansion shell 33 inward or outward by rotating the inner turntable 34, thereby changing the radial dimension.

[0068] In this embodiment, as Figure 9 , Figure 10 As shown, the top of the adjustment control lever 4 is used to unlock the adjustable winding disc 3, and the bottom is used to control the radial dimension of the adjustable winding disc 3;

[0069] In this embodiment, as Figure 11 , Figure 12 , Figure 13 As shown, depending on the length of the control shaft 43 extending into the shaft, different numbers of driven discs 44 are engaged, and after one rotation of a driven disc 44, it can drive the next driven disc 44 to rotate.

[0070] In this embodiment, as Figure 12 As shown, depending on the length of the control shaft 43, it is divided into four states, respectively engaging with the first, fourth, third, and fifth driven disks 44, and all of them. It also coordinates with the number of rotations between the driven disks 44 to achieve stepped rotation in different ranges.

[0071] In this embodiment, as Figure 15 , Figure 16 As shown, the distance between the input pulley 51 and the output pulley 55 can be adjusted but still maintain synchronous rotation, thereby adapting to different heights of the drive pulley 56;

[0072] In this embodiment, as Figure 17 , Figure 18 As shown, the transmission speed of the winding post 6 is adjusted according to the radial dimension of the adjustable winding disc 3. By using the stepless adjustment between the driven wheel 58 and the driving wheel 56, the linear speeds of the adjustable winding disc 3 and the winding post 6 are made equal.

[0073] In this embodiment, as Figure 19 , Figure 20 As shown, the winding post 6 achieves more uniform winding through the reciprocating movement of the cam.

[0074] The invention provides the following usage method and advantages: A wire drawing device for processing copper conductors for high-speed communication, with the following working process:

[0075] like Figures 1 to 20 As shown, during use, rotating the handle 41 unlocks the adjustable winding disc 3. According to the required parallelism, the control shaft 43 is inserted to different depths and rotated to adjust the radial dimension of the adjustable winding disc 3 to the required value. At the same time, the angular velocity of the winding column 6 is changed by the linear speed adjustment shaft 5. The drive motor 21 adjusts the speed and torque through the reduction gearbox 2. The two output shafts 23 are driven to rotate through the transmission sprocket 22 and the transmission chain 221. The wire drawing die head 13 is used for wire drawing and sprays coolant through the cooling nozzle 12 during the operation to draw the copper wire, thereby achieving the effect of adjusting the parallelism according to the required number of stretching times of the copper wire.
