Description

Technical Field

[0001] The invention relates to the technical field of copper body processing, in particular to a wire drawing device for processing high-speed communication copper conductors. Background Art

[0002] In the field of high-speed communications, copper conductor processing is crucial. Initially, high-purity copper is selected and smelted and purified to ensure the purity of the base material. Subsequently, a wire drawing process is used to draw the copper into fine wires of the required diameter. This process requires precise control of the drawing die parameters and drawing speed to ensure a smooth surface and precise dimensions.

[0003] Typically, during the processing of communication copper conductors, a wire drawing device is required to stretch the copper wire to the required size.

[0004] Depending on the size of the copper conductor after stretching, the thinner the copper conductor, the more times it needs to be drawn through the wire drawing die. Multiple wire drawing can effectively control the degree of deformation each time and reduce the generation of internal stress. During multiple wire drawing, as the copper conductor is stretched thinner, its linear speed will change. During the wire drawing process, according to the law of volume invariance, the cross-sectional area of ​​the copper conductor decreases, the length will increase accordingly, and the linear speed will also increase. In order to ensure the stability of the tension of the copper conductor during the winding process, it is necessary to adjust the diameter of the winding roller. If the roller diameter does not increase as the copper conductor becomes thinner, the copper conductor may be unevenly stacked during winding. Gradually increasing the roller diameter can coordinate the linear speed of the copper conductor with the drawing speed during winding, avoiding the copper conductor from being stretched due to excessive tension. The wire may break or become loose due to too little tension, and the wire must be wound at the same speed on both ends. If the wire is wound after the drawing is completed, the wire speed at the input and output ends must be equal. If the radius of the large reel is larger than that of the small reel, when their rotation speeds are the same, the wire speed of the large reel for winding the wire is greater than the wire speed of the small reel for winding the wire. This will cause the wire to accumulate on the small reel, which may cause knots and confusion, and may even cause the wire to be deformed or broken. On the contrary, if the radius of the small reel is larger than that of the large reel, the wire speed of the small reel for winding the wire is greater than the wire speed of the large reel for unwinding the wire. The wire will be pulled very tight, and staying in this state for a long time may easily cause the wire to be broken. This makes it difficult to balance the radial dimensions and angular velocities in different drawing modes of multi-parallel and single-parallel, resulting in inconvenience in use.

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

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] See also Figures 1 to 20 The present invention provides a technical solution: a wire drawing device for processing high-speed communication copper conductors, 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 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; The driving motor 21 adjusts the speed and torque through the reduction gear box 2, and drives the two output shafts 23 to rotate through the transmission sprocket 22 and the transmission chain 221. The wire drawing die 13 is used for drawing wire and sprays coolant through the cooling nozzle 12 during the operation; The outer surface of the output shaft 23 is provided with an adjustable winding drum 3, the bottom surface of the adjustable winding drum 3 is provided with an adjustment control lever 4, the outer surface of the device base 1 is provided with a line speed adjustment shaft 5, and one end of the line speed adjustment shaft 5 is provided with a winding column 6; There are two transmission sprockets 22 and two output shafts 23 , and the output shafts 23 extend through the inner surface of the working box 11 .

[0022] The adjustable winding drum 3 includes a drum base 31, which is fixedly connected to the outer surface of the output shaft 23. The outer surface of the drum base 31 is fixedly connected to a drum rib 311, and the outer surface of the drum rib 311 is provided with a linear groove 312. The outer surface of the output shaft 23 is fixedly connected to an outer baffle 32. The outer surface of the drum base 31 is slidably connected to an expansion shell 33, and the outer surface of the expansion shell 33 is fixedly connected to a positioning column 331. The inner surface of the expansion shell 33 slides. The outer surface of the disk base 31 is rotatably connected to the inner turntable 34, which has an arc-shaped groove 341 and a clamping block groove 342. The outer surface of the inner turntable 34 is fixedly connected to the outer surface of the inner turntable 34, which has an adjustment groove 351. The outer surface of the outer turntable 35 has an adjustment groove 351. The outer surface of the disk rib 311 is slidably connected to the ring clamping block 36, and the outer surface of the ring clamping block 36 is fixedly connected to the clamping block spring 361. Through the setting of the adjustable winding drum 3, during use, six groups of adjustable winding drums 3 are installed on each output shaft 23, and all the adjustable winding drums 3 are driven to rotate by the output shaft 23, and the copper conductor passes through the middle wire drawing die 13. Different between single and multiple wire drawing, multiple wire drawing requires the diameter of the winding roller to gradually increase to match the linear speed. The copper wire is wound on the adjustable winding drum 3 and wrapped on the surface of the expansion shell 33. The positioning column 331 on the expansion shell 33 is in contact with the straight groove 312 and the arc groove 341 at the same time, so that it can only move straightly in the straight groove 312. By rotating the arc groove 341, the positioning column 331 is moved on the straight groove 312. When moving outward, the expansion shell 33 moves away from the center of the circle to increase the radial size, and the distance between the expansion shells 33 increases, which is filled by the middle inner connecting plate 332, so that the radial size of the copper wire when wound on the adjustable winding drum 3 can be changed; The ring block 36 passes through the disk base 31 and is stuck in the block groove 342 of the inner turntable 34. There are six block grooves 342, so that there are six stages between the disk base 31 and the inner turntable 34, realizing step-by-step adjustment. When the block spring 361 is pressed into the block groove 342, the disk base 31 and the inner turntable 34 are connected, and the inner turntable 34 cannot rotate on the disk base 31, so that the position of the arc groove 341 is locked and the radial size of the expansion shell 33 is fixed. After lifting the ring block 36, the outer rotating ring 35 on the outside is turned to drive the inner turntable 34 to rotate, thereby controlling the radial size of the copper wire wound on the adjustable winding drum 3, and locking it after adjustment. The adjustable winding drum 3 rotates with the output shaft 23 and pulls the copper wire through the wire drawing die 13 in sequence.

[0023] There are six adjustable winding drums 3 on each output shaft 23, and they are distributed equidistantly. There are six linear grooves 312, expansion shells 33, and arcuate grooves 341, each of which is annularly distributed on the outer surface of the disk rib 311. Both sides of the inner connecting plate 332 are slidably connected to the inner surface of the expansion shell 33. The positioning column 331 is slidably connected to the inner surfaces of the linear grooves 312 and the arcuate grooves 341. There are six clamping block grooves 342, which are slidably connected to the ring clamping block 36. The ring clamping block 36 passes through the disk base 31 and is slidably connected to its inner wall. The ring clamping block 36 is made of iron, and the ends of the clamping block spring 361 are fixedly connected to the ring clamping block 36 and the disk rib 311 respectively. According to the different radial dimensions of the inner part of the adjustable winding drum 3, there are six stages between the drum base 31 and the inner turntable 34 to achieve stepless adjustment. These six stages are recorded as one, two, three, four, five, and six. When the required size of the copper wire is small and six wire drawing is required, the six adjustable winding drums 3 on each side are adjusted to one, two, three, four, five, and six, and the radial dimensions increase successively. At this time, the copper wire passes through the six drawing die heads 13 in sequence and is successively sleeved on the adjustable winding drums 3 with gradually increasing radial dimensions. If the required size of the copper wire is large and six wire drawing is not required, as shown in FIG. Only one wire drawing is required, and the six adjustable winding drums 3 are adjusted to a uniform radial size, and six groups of copper wires can be drawn at the same time to achieve six parallels. If two wire drawing operations are required to reach the required size, each two adjustable winding drums 3 are grouped together and adjusted to the required size, such as one-two-one-two-one-two, five-six-five-six-five, etc., and three groups of copper wires can be drawn at the same time. Similarly, three wire drawing operations can be carried out in two parallels, one-two-three-one-two-three or two-three-four-two-three-four, to achieve the effect of adjusting the parallel operation according to the required number of stretching operations of the copper wire.

[0024] The adjustment control lever 4 includes a rotating handle 41, which is rotatably connected to the inner surface of the working box 11, and the outer surface of the rotating handle 41 is fixedly connected to six equidistantly distributed magnetic blocks 411. The top surface of the device base 1 is fixedly connected to a lifting cylinder 42, and the output end of the lifting cylinder 42 is fixedly connected to a shaft sleeve 421. The inner surface of the shaft sleeve 421 is rotatably connected to a control shaft 43, and the outer surface of the control shaft 43 is fixedly connected to an engaging protrusion 431. The outer surface of the control shaft 43 is slidably connected to six equidistantly distributed driven disks 44, one end of the driven disk 44 is fixedly connected to a toggle rod 441, and the other end of the driven disk 44 is fixedly connected to a toggle slot 442. The inner surface of the driven disk 44 is provided with an engaging slot 443.

[0025] The magnetic block 411 is magnetically connected to the ring block 36 , the control shaft 43 passes through the inner surface of the working box 11 , and the driven disk 44 engages with the adjustment groove 351 ; When the handle 41 is turned, the magnetic blocks 411 are positioned upward or downward, and the ring clamping blocks 36 are attracted to the handle 41. At this time, the ring clamping blocks 36 no longer clamp the inner rotary disk 34, so that the inner rotary disk 34 can rotate freely. In the initial state, the driven disk 44 on the control shaft 43 is away from the adjusting groove 351. The lifting cylinders 42 on both sides lift the control shaft 43 and make the driven disk 44 mesh with the adjusting groove 351. At this time, according to the different meshing 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 adjusting groove 351, and every time the driven disk 44 rotates one circle, the outer rotating ring 35 at this location rotates and makes the ring clamping blocks 36 align with the block groove 342 of the next or previous sequence, thereby achieving a stepless adjustment effect. Six driven disks 44 are sleeved on the control shaft 43, corresponding to the six adjustable winding disks 3 respectively. At the same time, different numbers of engaging protrusions 431 are opened on the control shaft 43 for engaging with the driven disks 44. Only when the control shaft 43 is engaged can the driven disks 44 be driven to rotate. When not engaged, the driven disks 44 are stuck in the adjustment slots 351 and cannot rotate. After the driven disks 44 rotate one circle, the toggle rod 441 will contact the toggle slot 442 of the next driven disk 44, so that the previous driven disk 44 drives the next driven disk 44 to rotate. The same applies to the subsequent driven disks 44, but they must first rotate a full circle before they can drive the subsequent driven disks 44 to rotate, so that the rotation of the front and rear driven disks 44 differs by one circle. According to the different lengths of the control shaft 43, there are four states, corresponding to the one, two, three, and six parallel modes of the adjustable winding drum 3. The number of engagement protrusions 431 engaging the driven disks 44 is different. In the one parallel mode, only the first driven disk 44 is engaged. After the driven disk 44 rotates five circles, the subsequent driven disks 44 rotate four, three, two, one, and zero circles in sequence, so that the adjustable winding drum 3 is in the one, two, three, four, five, and six modes, and the radial size gradually increases, so that the copper wire is drawn six times. In the two parallel modes, the first and fourth driven disks 44 are engaged, and the following control After the shaft 43 rotates two circles, the second and fifth driven disks 44 rotate one circle, and the third and sixth driven disks 44 rotate zero circles. The adjustable winding disk 3 is in a one-two-three-one-two-three mode, and two parallel operations can be performed, respectively, for three wire drawing operations. The same is true for three parallel operations. The first, third, and fifth driven disks 44 drive the second, fourth, and sixth driven disks 44 to rotate. The adjustable winding disk 3 is in a one-two-one-two-one-two mode. In the six parallel mode, the engaging protrusion 431 engages with all the driven disks 44, driving all the driven disks 44 to rotate, thereby realizing synchronous adjustment of the radial size of the adjustable winding disk 3 according to the required parallel operation.

[0026] The linear speed adjustment shaft 5 includes an input pulley 51, which is fixedly connected to the outer surface of the output shaft 23. The other end of the input pulley 51 is rotatably connected to a first articulated arm 52. One end of the first articulated arm 52 is hingedly connected to an articulated seat 53. The outer surface of the articulated seat 53 is rotatably connected to an intermediate pulley 531. The other end of the articulated seat 53 is hingedly connected to a second articulated arm 54. The outer surface of the second articulated arm 54 is rotatably connected to an output pulley 55. One end of the output pulley 55 is fixed. It is connected to a driving wheel 56, the outer surface of which is slidably connected to a wheel cylinder 561, the outer surface of the device base 1 is fixedly connected to a mounting base 57, the inner surface of the mounting base 57 is slidably connected to six matching columns 571, the bottom surface of the driving wheel 56 is engaged with a driven wheel 58, the inner surface of the driven wheel 58 is slidably connected to a driven shaft 581, the outer surface of the driven shaft 581 is sleeved with a return spring 582, and the outer surface of the mounting base 57 is fixedly connected to an outer bracket 59.

[0027] The input pulley 51 and the intermediate pulley 531 form a belt drive, and the intermediate pulley 531 and the output pulley 55 form a belt drive. The driving pulley 56 passes through the second articulated 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 the inner wall of the driving pulley 56. 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 pulley 58. The driving pulley 56 drives the driven pulley 58 to rotate. Through the setting of the linear speed adjustment shaft 5, during use, after the radial size of the adjustable winding drum 3 is adjusted, the copper wire passes through the adjustable winding drum 3 and the drawing die head 13 in sequence, and is finally sleeved on the matching column 571. Six matching columns 571 are provided. According to the different radial sizes of the adjustable winding drum 3, the height of the copper wire after being extended is different, and it is sleeved on the matching column 571 of the corresponding height, and the matching column 571 is pushed out. One end of the driving wheel 56 is connected to the matching column 571 of the corresponding height, and at the same time, the wheel cylinder 561 rises on the other side to support the driving wheel 56. While the output shaft 23 drives the adjustable winding drum 3 to rotate, it will also divide a part of the power to drive the driving wheel 56 to rotate. According to the different radial sizes of the adjustable winding drum 3 and the different heights of the driving wheel 56, the speed of the driven wheel 58 is driven to be different, thereby matching the linear speed of the adjustable winding drum 3 and the winding column 6, ensuring that the copper wire is stably wound from the adjustable winding drum 3 to the winding column 6; 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 driving pulley 56 to rotate. The input pulley 51 and the output pulley 55 are respectively mounted on the first articulated arm 52 and the second articulated arm 54. The two articulated arms are hingedly connected. The distance between the input pulley 51 and the output pulley 55 is different due to the different rotation angles between them, while the distance between the input pulley 51 and the output pulley 55 and the intermediate pulley 531 remains unchanged. Therefore, the distance between the input pulley 51 and the output pulley 55 can be adjusted while still maintaining synchronous rotation, thereby adapting to different heights of the driving pulley 56. 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 squeezes the driven wheel 58 inward, and the contact point also changes. A vertical section is made at the contact point. The section can be regarded as the pitch circle of the driving wheel 56 when meshing. The closer the section is to the vertex of the arc surface of the driving wheel 56, the shorter the circumference of the section. The smaller the pitch circle of the driving wheel 56, the smaller the transmission ratio becomes, and the faster the speed of the driven wheel 58, the faster the gear ratio becomes. When the driving wheel 56 rises, the contact point between the driven wheel 58 and the driving wheel 56 moves outward again 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 post 6 can be adjusted according to the radial size of the adjustable winding drum 3, so that the linear speed between the adjustable winding drum 3 and the winding post 6 is always equal, the radial size of the adjustable winding drum 3 changes while the speed remains unchanged, and the angular velocity of the winding post 6 changes accordingly while the radial size remains unchanged, that is, R3ω3=R6ω6.

[0028] The winding column 6 includes a fixed rotating shaft 61, which is fixedly connected to the driven wheel 58. The inner surface of the fixed rotating shaft 61 is slidably connected to the movable rotating shaft 62. One end of the movable rotating shaft 62 is fixedly connected to the winding shaft 621. The outer surface of the winding shaft 621 is slidably connected to the push-pull seat 63. The inner surface of the push-pull seat 63 is fixedly connected to the contact ball protrusion 631. The inner surface of the outer bracket 59 is rotatably connected to the winding pulley 64. One end of the winding pulley 64 is fixedly connected to the cylindrical cam 641.

[0029] The contact ball protrusion 631 engages 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-helical. The winding pulley 64 is connected to the driven shaft 581. The cylindrical cam 641 passes through the push-pull seat 63. Through the setting of the winding column 6, during use, the driven wheel 58 drives the fixed rotating shaft 61 to rotate, the position of the fixed rotating shaft 61 is fixed, and 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, and can move on the fixed rotating shaft 61 and rotate synchronously. The winding shaft 621 inherits the movable and synchronous rotation effects 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, and a cam structure is formed by contacting the ball protrusion 631. The cam groove is a double helix. When it rotates to one end, it will enter the other spiral groove to achieve reverse movement, so that the push-pull seat 63 moves back and forth. In this way, when winding the copper wire, the copper wire can be evenly wound on the surface of the winding shaft 621 to prevent accumulation in the same position.
