Description

Technical Field

[0001] This invention relates to the field of copper wire straightening technology, and more specifically, to a copper wire straightening processing device for processing bundled cables. Background Technology

[0002] In the field of bundled cable manufacturing, copper wire straightening is a crucial process that determines the electrical performance and mechanical strength of the cable. During the unwinding process, copper wires inevitably experience various bends and twists, requiring straightening to eliminate internal stress and achieve a straight state before proceeding to the subsequent stranding process. However, existing copper wire straightening equipment generally suffers from the following technical problems: First, poor equipment versatility. When dealing with copper wires of different diameters, the spacing of the straightening rollers is difficult to adjust quickly, often requiring machine downtime for parts replacement or complex manual adjustments, resulting in low production efficiency. Second, uneven tension control. During straightening, copper wires elongate to varying degrees depending on their degree of bending—severely bent wires elongate significantly and increase in length during straightening, while straighter wires elongate less. However, existing equipment cannot automatically match the traction speed according to the actual elongation of the wire, resulting in inconsistent tension, severely affecting the straightening effect and the surface quality of the copper wire. Third, dead zones exist in straightening. Traditional straightening devices apply straightening force only in limited directions, making it difficult to achieve uniform straightening of the copper wire throughout its entire circumference. The aforementioned problems have hindered further improvements in cable production quality. Therefore, it is necessary to provide a copper wire straightening device for bundled cable processing to solve the problems mentioned in the background art. Summary of the Invention

Two variable diameter straightening devices are provided on the left and right sides, fixed on the workbench, located on the right side of the wire feeding mechanism, and the two sets of variable diameter straightening devices have the same structure. Two height positioning brackets are symmetrically distributed on the left and right sides and are set between the mixed take-up mechanism of the variable diameter straightening device; An adaptive tension compensation device is installed between two height positioning brackets.

[0004] Furthermore, preferably, the variable diameter straightening device includes: The base is fixed to the workbench; Two support components are symmetrically distributed at the front and back and fixed to the base; The guide positioning component is fixed on the base, and the side of the support component is coaxially arranged with the copper wire; The straightening component is fixed to the support member, and its side center is fixedly connected to the guide positioning member; The diameter adjustment component is located on the opposite side of the straightening component, opposite to the guide positioning component.

[0005] Furthermore, preferably, the straightening component includes: The fixed disc is vertically positioned and fixed between the support components; The central channel runs through the center of the fixed disc and corresponds to the guide positioning component. Multiple adjusting slides are arranged in a ring, passing through the fixed disc, with one end facing the center connected to the central channel, and the adjusting slides in the two sets of the variable diameter straightening devices are staggered. The telescopic shaft is set in correspondence with the adjusting slide, with one end fixed to the inner wall of the outer end of the adjusting slide; The U-shaped part is slidably set in the adjusting slide, and the closed end is fixedly connected to the other end of the telescopic shaft. The straightening wheel is rotatably mounted at the open end of the U-shaped part, and fits against the side wall of the copper wire.

[0006] Furthermore, preferably, the variable diameter adjustment assembly includes: The adjusting toothed ring is located on the opposite side of the guide positioning element on the straightening assembly; An arc-shaped slide is set on the adjusting gear ring, corresponding to the adjusting slide; The transmission slider is slidably mounted on the arc-shaped slide rail and is fixedly connected to the side of the U-shaped part in the corresponding adjustment slide rail; The drive gear is located inside the base and meshes with the lower part of the adjusting gear ring; The drive shaft is fixed at the center of the drive gear and is connected to a motor drive. The drive gears in two adjacent sets of diameter-changing straightening devices are driven by the same drive shaft.

[0007] Furthermore, as a preferred embodiment, the height positioning bracket consists of a support column and a positioning bushing fixed to the top of the support column, wherein the center of the positioning bushing is on the same axis as the copper wire.

[0008] Furthermore, preferably, the adaptive tension compensation device includes: The chain conveyor assembly is positioned between two height positioning brackets; Fixed support plate, fixed connection chain conveyor assembly and worktable; The drive motor is fixedly connected to the sprocket shaft in the chain conveyor assembly; The support positioning body is set inside the chain conveyor assembly and is fixedly connected to the worktable, with its top fitting against the top inner wall of the chain conveyor assembly; Tension compensation components are fixed to the chain plates of the chain conveyor assembly.

[0009] Furthermore, preferably, the tension compensation component includes: The connecting groove is fixed to the chain plate of the chain conveyor assembly; The bearing surface is fixed inside the connecting groove; Two sets of elastic clamping mechanisms are symmetrically distributed front and back and are set on the bearing surface.

[0010] Furthermore, preferably, the elastic clamping mechanism includes: The fixing body is fixed above the end of the bearing surface; The elastic telescopic component is connected at one end to the inside of the fixed body; The movable body is slidably mounted on the bearing surface and is fixedly connected to the other end of the elastic telescopic component; A fixed shaft is fixed to the moving body; The compensation wheel is rotatably mounted on a fixed shaft, and the upper and lower edges of the compensation wheel are arc-shaped, with the sidewalls corresponding to the copper wires being higher than the top of the connecting groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are: In this invention, by adjusting the fit between the toothed ring and the arc-shaped slide and driving synchronously with the same drive shaft, multiple straightening wheels can move radially synchronously, achieving the effects of quickly adapting to copper wires of different diameters, eliminating the need to stop the machine to replace parts, and improving versatility and production efficiency. By adjusting the staggered arrangement of the slide rails in the two sets of variable diameter straightening devices, the clamping positions of the front and rear straightening wheels in the circumferential direction of the copper wire are staggered, so as to achieve the effect of straightening and covering the copper wire in the entire circumference without dead angles. The chain conveyor drives the tension compensation component to circulate, and the bearing positioning body keeps the top section horizontal. The speed of the compensation wheel changes automatically with the elongation rate, so as to achieve the effect of automatic matching between traction speed and elongation rate and maintaining constant tension. The fixed body and the moving body are connected by an elastic telescopic component. The compensation wheel is rotatably set on the fixed shaft, so that the passive rotation of the compensation wheel transforms the sliding friction into rolling friction, thereby reducing the surface damage of the copper wire and protecting the surface quality. The curved edges of the compensation wheel ensure a smooth transition in the contact area when the copper wire is inserted and removed. Combined with the precise guidance of the positioning bushing, this allows the copper wire to smoothly enter and exit the elastic clamping mechanism, preventing jamming and machine stoppage.

[0013] Please see Figures 1 to 8 In this embodiment of the invention, a copper wire straightening device for processing bundled cables includes: Workbench 1; The wire feeding mechanism 2 is located on the left side of the workbench 1 and feeds out the copper wire at a constant speed. The take-up mechanism 3 is located on the right side of the workbench 1, corresponding to the pay-off mechanism 2, and adaptively collects the copper wire through speed change; Two variable diameter straightening devices 4 are provided on the left and right sides and fixed on the workbench 1, located on the right side of the wire feeding mechanism 2, and the two sets of variable diameter straightening devices 4 have the same structure. Two height positioning brackets 5 are symmetrically distributed on the left and right sides and are set between the variable diameter straightening device 4 and the mixed take-up mechanism 3. An adaptive tension compensation device 6 is installed between two height positioning brackets 5.

[0014] In this embodiment, the variable diameter straightening device 4 includes: Base 41 is fixed on workbench 1; Two support members 42 are symmetrically distributed at the front and back and fixed on the base 41; The guide positioning component 43 is fixed on the base 41, and the side of the support component 42 is coaxially arranged with the copper wire. The straightening component 44 is fixed on the support 42, and its side center is fixedly connected to the guide positioning component 43; The diameter adjustment component 45 is disposed on the straightening component 44 on the opposite side of the guide positioning component 43.

[0015] In other words, after the copper wire is led out from the wire feeding mechanism 2, it first enters the diameter-changing straightening device 4. Before entering the straightening assembly 44, the copper wire passes through the guide positioning part 43 on the left side of the diameter-changing straightening device 4. The inner hole of the guide positioning part 43 is coaxially set with the copper wire, and its inner diameter is slightly larger than the maximum diameter of the copper wire. It plays a preliminary guiding and limiting role for the copper wire, preventing the copper wire from deviating from the central axis due to the swing during the wire feeding process. Subsequently, the copper wire enters the central area of ​​the straightening assembly 44. The copper wire is clamped by the straightening assembly 44. During the continuous feeding of the copper wire, multiple straightening assemblies 44 apply alternating bending stress to the copper wire, causing the copper wire to undergo plastic deformation, thereby achieving the straightening purpose. After the copper wire is straightened, it is guided out by the guide positioning part 43 on the right side of the diameter-changing straightening device 4. When changing to copper wire specifications of different diameters, the diameter adjustment assembly 45 controls the straightening assembly 44 to adjust, so that the straightening assembly 44 keeps in contact with the side wall of the copper wire.

[0016] In a preferred embodiment, the guide positioning component 43 pre-positions the copper wire before it enters the straightening zone, ensuring that the copper wire is always transported along the central axis, avoiding lateral movement of the copper wire during the straightening process, and improving straightening accuracy. The fixed connection between the base 41 and the worktable 1 ensures the stability of the entire device during high-speed operation. The symmetrically distributed support components 42 at the front and rear ensure that the straightening component 44 is subjected to uniform force, avoiding eccentric load and vibration caused by unilateral support. The variable diameter adjustment component 45 enables the equipment to quickly adapt to copper wires of different diameters without stopping the machine to replace parts, significantly improving the equipment's versatility and production efficiency.

[0017] In this embodiment, the straightening component 44 includes: The fixed disc 441 is vertically positioned and fixed between the support members 42; The central channel 442 passes through the center of the fixed disc 441 and corresponds to the guide positioning element 43. Multiple adjusting slides 443 are arranged in a ring, passing through the fixed disc 441, with one end facing the center connected to the central channel 442, and the adjusting slides 443 in the two sets of the variable diameter straightening device 4 are staggered. The telescopic shaft 444 is correspondingly provided with the adjusting slide 443, and one end is fixed on the inner wall of the outer end of the adjusting slide 443; U-shaped part 445 is slidably disposed in the adjusting slide 443, and its closed end is fixedly connected to the other end of the telescopic shaft 444. The straightening wheel 446 is rotatably mounted at the open end of the U-shaped part 445 and fits against the side wall of the copper wire.

[0018] In other words, the copper wire passes through the central channel 442 and enters the straightening space formed by multiple straightening rollers 446. When the diameter adjustment component 45 is driven, the U-shaped part 445 slides radially within the adjustment slide 443. Specifically, when the U-shaped part 445 slides outward, the telescopic shaft 444 is compressed, the straightening rollers 446 move away from the central channel 442, and the straightening space increases, making it suitable for copper wires with larger diameters. When the U-shaped part 445 slides towards the center, the telescopic shaft 444 extends, the straightening rollers 446 move closer to the central channel 442, and the straightening space decreases, making it suitable for copper wires with smaller diameters. When the copper wire is continuously fed, the straightening rollers 446 are passively rotated under the friction of the copper wire, rolling and straightening the surface of the copper wire. The rotation of the straightening rollers 446 effectively reduces the sliding friction between the straightening rollers and the copper wire, avoiding scratches on the surface of the copper wire.

[0019] In a preferred embodiment, the telescopic shaft 444 plays a dual role in this process. First, as an elastic connecting element, it provides a stable telescopic stroke when the U-shaped part 445 slides, ensuring the smoothness of the position adjustment of the straightening wheel 446. Second, during the straightening process, the telescopic shaft 444 applies a continuous outward pushing force to the U-shaped part 445, which, together with the diameter adjustment component 45, keeps the straightening wheel 446 in contact with the copper wire, ensuring that the straightening wheel 446 is always in contact with the side wall of the copper wire, avoiding poor contact caused by slight fluctuations in the diameter of the copper wire. The adjustment slides 443 in the two sets of diameter straightening devices 4 are staggered, so that the clamping positions of the straightening wheel 446 in the first set of straightening devices and the clamping positions of the straightening wheel 446 in the second set of straightening devices are staggered in the circumferential direction of the copper wire. When the copper wire passes through the two sets of diameter straightening devices 4 in sequence, the straightening wheels 446 in the front and rear sets apply straightening force to the copper wire from different circumferential angles, achieving a larger coverage of the outer wall of the copper wire.

[0020] In this embodiment, the variable diameter adjustment component 45 includes: The adjusting toothed ring 451 is located on the straightening assembly 44 on the opposite side of the guide positioning member 43; The arc-shaped slide 452 is set on the adjusting gear ring 451 and corresponds to the adjusting slide 443; The transmission slider 453 is slidably mounted on the arc-shaped slide rail 452 and is fixedly connected to the side of the U-shaped part 445 in the corresponding adjustment slide rail 443. The drive gear 454 is disposed inside the base 41 and meshes with the lower part of the adjusting gear ring 451; The drive shaft 455 is fixed at the center of the drive gear 454 and is connected to a motor drive. The drive gears 454 in two adjacent sets of diameter-changing straightening devices 4 are driven by the same drive shaft 455.

[0021] In other words, when the position of the straightening wheel 446 needs to be adjusted to accommodate copper wires of different diameters, the motor drives the drive shaft 455 to rotate. Simultaneously, the drive shaft 455 drives the drive gears 454 in the two adjacent sets of variable diameter straightening devices 4 to rotate synchronously. The rotation of the drive gears 454 drives the adjusting gear ring 451, which meshes with it, to rotate. Taking the clockwise rotation of the adjusting gear ring 451 as an example, the arc-shaped slide rail 452 on the adjusting gear ring 451 rotates synchronously with the adjusting gear ring 451. The arc-shaped slide rail 452 is an arc-shaped channel, and its radial distance from the center of the adjusting gear ring 451 gradually changes along the arc length direction. When the arc-shaped slide rail 452 rotates, the transmission slider 453, which is slidably disposed within the arc-shaped slide rail 452, is pushed by the groove wall of the arc-shaped slide rail 452 and moves outward along the adjusting slide rail 443 on the fixed disc 441. Furthermore, due to the interaction between the transmission slider 453 and the U-shaped part 445... With a fixed connection at the side, the movement of the transmission slider 453 drives the U-shaped part 445 to slide outward synchronously along the adjusting slide 443. When the U-shaped part 445 moves outward, the telescopic shaft 444 is compressed, and the straightening wheel 446 moves away from the central channel 442, increasing the straightening space and adapting to larger diameter copper wires. Conversely, when the adjusting gear ring 451 rotates counterclockwise, the arc-shaped slide 452 pushes the transmission slider 453 to move towards the center along the adjusting slide 443, and the U-shaped part 445 slides towards the center accordingly. The telescopic shaft 444 extends, and the straightening wheel 446 moves closer to the central channel 442, reducing the straightening space and adapting to smaller diameter copper wires. At the same time, the drive shaft 455 drives the drive gear 454 in the two adjacent sets of variable diameter straightening devices 4, so that the adjusting gear ring 451 in the two sets of variable diameter straightening devices 4 rotates synchronously, realizing the synchronous adjustment of the front and rear sets of straightening wheels 446.

[0022] In this embodiment, the height positioning bracket 5 consists of a support column 51 and a positioning bushing 52 fixed to the top of the support column 51. The center of the positioning bushing 52 is on the same axis as the copper wire.

[0023] In other words, before entering the adaptive tension compensation device 6, the straightened copper wire first passes through the positioning sleeve 52 of the left height positioning bracket 5. The center of the positioning sleeve 52 is on the same axis as the copper wire, which guides and positions the copper wire, ensuring that the copper wire enters the adaptive tension compensation device 6 at the correct angle and height. After being processed by the adaptive tension compensation device 6, the copper wire passes through the positioning sleeve 52 of the right height positioning bracket 5 again before entering the take-up mechanism 3, ensuring that the copper wire enters the take-up mechanism 3 at the correct angle and height. Under the combined action of the two height positioning brackets 5, the copper wire and the adaptive tension compensation device 6 cooperate with each other to maintain the stability of the copper wire tension and ensure continuous delivery. This effectively prevents the copper wire from drooping due to gravity before entering the adaptive tension compensation device 6 or from swinging after leaving the adaptive tension compensation device 6, ensuring that the copper wire can accurately cooperate and disengage with the tension compensation component 65. This avoids downtime caused by the copper wire getting stuck or failing to disengage, and improves the continuity and reliability of equipment operation.

[0024] In this embodiment, the adaptive tension compensation device 6 includes: The chain conveyor assembly 61 is disposed between two height positioning brackets 5; Fixed support plate 62, fixedly connecting chain conveyor assembly 61 and worktable 1; The drive motor 63 is fixedly connected to the sprocket shaft in the chain conveyor assembly 61; The bearing positioning body 64 is set inside the chain conveyor assembly 61 and is fixedly connected to the worktable 1, with its top abutting against the top inner wall of the chain conveyor assembly 61. Tension compensation component 65 is fixed on the chain plate of chain conveyor assembly 61.

[0025] In other words, the drive motor 63 operates, driving the sprocket in the chain conveyor assembly 61 to rotate via the sprocket shaft. The sprocket drives the annular chain plate to continuously circulate. The tension compensation component 65, fixed on the chain plate, moves with the chain plate, forming a cyclic conveying. The tension compensation component 65, located in the upper part (i.e., the top section) of the chain conveyor assembly 61, is used to contact the copper wire and perform the tension compensation function. When the tension compensation component 65 moves with the chain plate to the top section, the bearing positioning body 64 provides bottom-up support to the chain plate and the tension compensation component 65 on the chain plate in that section. The force keeps the tension compensation component 65 in this section horizontal. The tension compensation component 65 continuously circulates with the chain plate, passing under the left height positioning bracket 5, engaging with the copper wire, carrying the copper wire a distance to the right, and then passing under the right height positioning bracket 5, separating from the copper wire. It then goes around the sprocket and enters the lower section to return, preparing for the next cycle. The cyclic movement structure of the chain plate conveyor component 61 ensures that the tension compensation component 65 can continuously contact and separate from the copper wire, achieving continuous and uninterrupted tension compensation for the copper wire. In this embodiment, the tension compensation component 65 includes: The connecting groove 651 is fixed on the chain plate of the chain plate conveyor assembly 61; The bearing surface 652 is fixed inside the connecting groove 651; Two sets of elastic clamping mechanisms 653 are symmetrically distributed front and back and are set on the bearing surface 652.

[0026] In other words, the connecting groove 651 moves synchronously with the chain plate, driving the entire tension compensation component 65 to move along the circulation path. When the tension compensation component 65 moves to the top section of the chain plate conveying component 61, the bearing surface 652 is in a horizontal state under the support of the bearing positioning body 64. Under the guidance of the left height positioning bracket 5, the copper wire enters the tension compensation component 65 area in the same top section. Two sets of elastic clamping mechanisms 653 are symmetrically distributed front and back and are arranged opposite each other. The copper wire passes between the two sets of elastic clamping mechanisms 653 and is clamped from the front and back sides. In the clamping state, the copper wire moves forward together with the tension compensation component 65. When the tension compensation component 65 moves to the right end of the chain plate conveying component 61, under the guidance of the right height positioning bracket 5, the copper wire disengages from the two sets of elastic clamping mechanisms 653 and continues to be conveyed towards the take-up mechanism 3.

[0027] In this embodiment, the elastic clamping mechanism 653 includes: Fixing body 6531 is fixed above the end of bearing surface 652; The elastic telescopic component 6532 is connected at one end to the inner side of the fixed body 6531; The movable body 6533 is slidably disposed on the bearing surface 652 and fixedly connected to the other end of the elastic telescopic member 6532; The fixed shaft 6534 is fixed on the movable body 6533; The compensation wheel 6535 is rotatably mounted on the fixed shaft 6534, and the upper and lower edges of the compensation wheel 6535 are arc-shaped, with the sidewall corresponding to the copper wire being higher than the top of the connecting groove 651.

[0028] In other words, before the copper wire is inserted, the elastic telescopic member 6532 is in its naturally extended state, and the moving body 6533 is located at one end near the center of the copper wire. The distance between the compensation wheels 6535 in the two sets of elastic clamping mechanisms 653 is the smallest, but this distance is slightly smaller than the diameter of the copper wire, so that the copper wire needs to overcome the elastic force of the elastic telescopic member 6532 to push the compensation wheels 6535 away when it enters. When the copper wire is inserted, the copper wire enters between the two sets of compensation wheels 6535 under the guidance of the left height positioning bracket 5. The copper wire first contacts the arc-shaped edge of the top of the compensation wheel 6535. The contact between the copper wire and the compensation wheel 6535 starts from the outermost edge of the arc surface, and the contact area gradually increases. As the distance between the two sets of compensating wheels 6535 gradually increases, a smooth transition is formed. Driven by the copper wire, the moving body 6533 overcomes the elastic force of the elastic telescopic member 6532 and slides away from the center of the copper wire on the bearing surface 652. The distance between the two sets of compensating wheels 6535 increases. After the copper wire is fully inserted, under the restoring force of the elastic telescopic member 6532, the two sets of compensating wheels 6535 clamp the copper wire from both the front and rear sides. In the clamping and conveying state, the copper wire is clamped between the two sets of compensating wheels 6535 and moves horizontally to the right along with the tension compensation component 65. During this process, friction is generated between the compensating wheels 6535 and the copper wire. Driven by the copper wire, the compensating wheels 6535 rotate around the solid... The rotation of the fixed axis 6534 and the rotation of the compensation wheel 6535 transform sliding friction into rolling friction, effectively reducing damage to the surface of the copper wire. When the copper wire is disengaged, the tension compensation component 65 carries the copper wire to the right end of the chain conveyor component 61. Guided by the right-side height positioning bracket 5, the copper wire is pulled out between the two sets of compensation wheels 6535. The arc-shaped edges on the upper and lower sides of the compensation wheel 6535 also play a smooth transition role during the disengagement process, allowing the copper wire to smoothly disengage from the clamp and avoiding sudden ejection or jamming. After disengagement, under the action of the elastic telescopic component 6532, the moving body 6533 resets, and the two sets of compensation wheels 6535... The spacing between 535 returns to its initial state, preparing for the next cycle of clamping. It should be noted that the elastic telescopic component 6532 in the elastic clamping mechanism 653 only has the ability to clamp and move the copper wire without external force. The clamping force is relatively weak. Under the continuous feeding of the copper wire, the elastic clamping mechanism 653 can drive the copper wire to be continuously fed. When the copper wire is stuck or detached between the tension compensation components 65, it will not affect the copper wire. Furthermore, in order to prevent slight impact on the copper wire, an auxiliary structure can be set. When the copper wire is stuck or detached, the auxiliary compensation wheel 6535 moves to both sides and resets after the copper wire is stuck or detached.

[0029] In a preferred embodiment, when the copper wire has varying degrees of elongation after straightening, it moves under the drive of the tension compensation component 65. The copper wire applies a reverse pulling force to the compensation wheel 6535. Initially, the conveying speed of the chain conveyor component 61 is faster than that of the wire feeding mechanism 2, and the movement speed of the tension compensation component 65 is greater than that of the copper wire. This speed difference causes the compensation wheel 6535 to slide relative to the copper wire as it moves forward with the tension compensation component 65. The rotational speed of the compensation wheel 6535 reflects this relative sliding state. As the elongation and length of the copper wire increase, the copper... When the reverse tension of the wire on the compensation wheel 6535 decreases, the friction between the compensation wheel 6535 and the copper wire decreases, and the rotational speed of the compensation wheel 6535 decreases, the tension compensation component 65 drives the copper wire forward with a greater speed advantage, enabling the copper wire to achieve a faster conveying speed to compensate for the length increase caused by the extension of the copper wire and prevent the copper wire from slack. When the elongation of the copper wire decreases and the tension increases, the reverse tension of the copper wire on the compensation wheel 6535 increases, the friction between the compensation wheel 6535 and the copper wire increases, the rotational speed of the compensation wheel 6535 increases, the dragging effect of the tension compensation component 65 on the copper wire weakens, and the copper wire conveying speed slows down to prevent the copper wire from being over-tensioned.

[0030] In practice, after the copper wire is drawn out by the wire feeding mechanism 2 at a constant speed, it first enters the variable diameter straightening device 4. Before entering the straightening assembly 44, the copper wire passes through the guide positioning piece 43 on the left side of the variable diameter straightening device 4 for pre-positioning. Then, it passes through the central channel 442 at the center of the fixed disc 441 and enters the straightening space formed by multiple straightening wheels 446. When changing to copper wire of different diameters, the motor drives the drive shaft 455 to rotate. The drive shaft 455 drives the drive gears 454 in the two adjacent sets of variable diameter straightening devices 4 to rotate synchronously. The drive gears 454 drive the adjusting gear ring 451 to rotate. The arc-shaped slide 452 on the adjusting gear ring 451 rotates synchronously with the adjusting gear ring 451 and pushes the transmission slider 453 inside it to slide along the adjusting slide 443. The transmission slider 453 drives the U-shaped part 445 to move radially along the adjusting slide 443. When the U-shaped part 445 slides outward, the telescopic shaft 444 retracts and the straightening wheel 446 moves away from the central channel 442, increasing the straightening space. When the U-shaped part 445 slides towards the center, the telescopic shaft 444 extends and the straightening wheel 446 moves closer to the central channel 442, decreasing the straightening space. This automatically adapts to copper wires of different diameters. During the continuous feeding of the copper wire, the adjusting slides 443 in the two sets of variable diameter straightening devices 4 are staggered, so that the front and rear straightening wheels 446 apply alternating bending stress to the copper wire from different circumferential angles for rolling straightening. The straightened copper wire is guided out by the guide positioning part 43 on the right-side variable diameter straightening device 4, and then passes through the positioning bushing 52 of the left-side height positioning bracket 5. Guided to the correct height and angle, the copper wire enters the adaptive tension compensation device 6. The drive motor 63 drives the annular chain plate of the chain plate conveying assembly 61 to continuously circulate through the sprocket shaft. The tension compensation component 65 fixed on the chain plate moves synchronously. The bearing positioning body 64 provides bottom-up support to the chain plate and tension compensation component 65 in the top section to keep them horizontal. Under the combined action of the left height positioning bracket 5 and the adjacent tension compensation component 65, the copper wire enters between the two sets of elastic clamping mechanisms 653. The copper wire first contacts the arc-shaped edge of the top of the compensation wheel 6535 and pushes the moving body 6533 to overcome the elastic force of the elastic telescopic member 6532 and slide outward, increasing the distance between the two sets of compensation wheels 6535. The copper wire is completely... After being engaged, the copper wire is held in place by two sets of compensating wheels 6535 under the restoring force of the elastic telescopic component 6532 from both the front and rear sides. Driven by the copper wire, the compensating wheels 6535 rotate around the fixed shaft 6534. Since the conveying speed of the chain conveyor assembly 61 is faster than that of the wire feeding mechanism 2, a speed difference exists between the tension compensating component 65 and the copper wire, resulting in relative sliding. When the copper wire's elongation increases due to straightening, and its length increases, the reverse tension of the copper wire on the compensating wheel 6535 decreases, and the rotational speed of the compensating wheel 6535 decreases. The tension compensating component 65 then drives the copper wire forward with a greater speed advantage to compensate for the length increase and prevent the copper wire from slackening. Conversely, when the copper wire's elongation decreases and the tension increases, the reverse tension of the copper wire on the compensating wheel 6535 increases, and the rotational speed of the compensating wheel 6535 increases.The tension compensation component 65 reduces the drag force on the copper wire, slowing down the wire's feed speed and preventing excessive tension. This, through automatic changes in the rotational speed of the compensation wheel 6535, automatically matches the traction speed with the copper wire's elongation, maintaining constant tension. After being output by the adaptive tension compensation device 6, the copper wire smoothly disengages from between the two sets of compensation wheels 6535 under the combined action of the right-side height positioning bracket 5 and the adjacent tension compensation component 65. After disengagement, the moving body 6533 resets under the action of the elastic telescopic component 6532, preparing for the next cycle of clamping. Subsequently, the copper wire is guided by the positioning sleeve 52 of the right-side height positioning bracket 5 into the take-up mechanism 3. The take-up mechanism 3 automatically adjusts its collection process according to the copper wire's feed speed, thus completing the entire straightening process.
