Description

Technical Field

[0001] This invention relates to the field of wire production equipment technology, and in particular to a copper wire stranding production equipment and method. Background Technology

[0002] In some copper wire production processes, stranding equipment is used to strand and wire the copper wires. The stranded copper wires have good electrical properties and improved mechanical properties.

[0003] A common stranding method involves stranding multiple continuously rotating copper wires onto the surface of a main cable located in the middle, thus achieving the stranding and wire-winding of multiple copper wires. During the stranding and wire-winding process, the stranding angle between the copper wires and the main cable needs to be adjusted according to the actual production conditions. A relatively large stranding angle results in a softer conductor and better flexibility. If the stranding angle is too small, it may lead to increased resistance and inductance, affecting the current transmission efficiency. Therefore, it is necessary to control the stranding angle within a suitable range.

[0004] Some traditional methods of adjusting the twisting angle are achieved by moving the position of the twisting disc. Moving the twisting disc away from the twisting head can reduce the twisting angle, while moving it closer to the twisting head can increase the twisting angle. However, moving the twisting disc requires extensive adjustment of the twisting equipment and occupies a large volume of space in the production workshop.

[0005] Another method of adjusting the stranding angle involves setting a linearly adjustable guide device on the side wall of the stranding disc. By driving the guide device to move along the radial direction, the stranding angle can be adjusted by adjusting the position of the guide device. However, the above adjustment method is limited by the structure and method of adjustment. In order to avoid bending and damage to the copper wire, the guide device is difficult to move to a more inner or outer position. The range of its adjustment angle is limited by the specific structure and size of the stranding disc, making it difficult to strand different types of copper wires. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a copper wire stranding production equipment and method. This invention can adjust the stranding angle of the copper wire at a position far from the stranding reel, with a large adjustment range and fewer limitations imposed by the stranding reel and related structures. At the same time, it reduces bending damage to the copper wire during the angle adjustment process, satisfying the stranding production and processing needs of different types of copper wires.

When the hydraulic telescopic rod extends, it squeezes control oil into the first drive assembly to control the first drive assembly to drive the first positioning plate to deflect in a first direction. When the hydraulic telescopic rod retracts, it draws out the control oil from the first drive assembly to control the first drive assembly to drive the first positioning plate to deflect in a second direction.

[0011] Preferably, the hydraulic telescopic rod has an arc-shaped cross-section and includes an arc-shaped hydraulic base.

[0013] Preferably, the position control rod is rotatably connected to the winch via a mounting base, and a deflection angle detector is provided on the side wall of the mounting base.

[0014] Preferably, the second guide body further includes a hydraulic control joint connected to the second positioning plate, the hydraulic control joint being connected to the unwinding device for controlling the unwinding state of the unwinding device.

[0015] Preferably, the unwinding device includes an unwinding body and an unwinding drum sleeved on the outside of the unwinding body.

[0018] The beneficial effects of this invention are as follows:

[0019] Compared with existing technologies, the above structural design allows the second drive component to adjust the position control rod to deflect around a predetermined axis, enabling adjustment of the stranding angle of the copper wire at a position far from the stranding disc.

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] To address the problems mentioned in the background art, see Appendix Figure 1 - Appendix Figure 11 A copper wire stranding production device includes a stranding head 100 for stranding copper wires 200 and main cable 700 together, and a stranding disc 800 for guiding the copper wires 200 and main cable 700. Several first guide bodies 300 are provided on the outside of the stranding disc 800. The first guide bodies 300 can guide the moving copper wires 200. The stranding disc 800 can rotate directionally around a horizontal axis. The copper wires 200 can move directionally during the rotation. Multiple copper wires 200 are wound and stranded on the surface of the main cable 700 at the stranding head 100 to realize the stranding production of copper wires 200.

[0034] Specifically, the first guide body 300 includes a first positioning disk 320 and two first guide rollers 330, which are rotatably connected to the first positioning disk 320. The first guide body 300 also includes a first drive assembly 310 for controlling the deflection angle of the first positioning disk 320. The first drive assembly 310 can adjust the deflection angle of the first positioning disk 320 and the first guide rollers 330, and can adjust according to the direction of the copper wire 200 to avoid damage caused by excessive bending angle of the copper wire 200. When the twisting angle of the copper wire 200 changes from a small angle to a large angle, the first drive assembly 310 controls the first positioning disk 320 and the first guide rollers 330 to follow the attached... Figure 2 and attached Figure 4The copper wires 200 on both sides of the first guide body 300 are rotated counterclockwise to adjust them to a relatively symmetrical guiding state, so as to avoid damage caused by different bending angles on both sides of the copper wires 200 due to the constant first guide body 300.

[0035] It should be noted that the first guide roller 330 here can be set to a structure that is thinner in the middle and thicker on both sides, which can effectively limit the copper wire 200 on both sides and enable the high-speed rotation of the twisting disc 800.

[0036] It should also be noted that when the copper wire 200 is at a small twisting angle, the copper wire 200 is in contact with the first guide roller 330 located at the top, and when the copper wire 200 is at a large twisting angle, the copper wire 200 is in contact with the first guide roller 330 located at the bottom. The first guide rollers 330 located on both sides can limit and guide the copper wire 200 in different states, ensuring the stability of the twisting and conveying of the copper wire 200.

[0037] It also includes a position control device 400 that controls the first guide body 300 to deflect around a predetermined axis. The device controls the first guide body 300 to deflect to different angle positions to adjust the twisting angle between the copper wire 200 and the main cable 700. Here, the first guide body 300 can move around a predetermined arc track, which is located on a virtual circumference. By setting the above adjustment method, compared with the traditional linear movement adjustment, the first guide body 300 can be located on the side relatively far away from the twisting disc 800, which can reserve sufficient lateral space for the copper wire 200 between the twisting disc 800 and the first guide body 300. This further effectively avoids the copper wire 200 on both sides of the first guide body 300 from bending at too large an angle, and avoids the copper wire 200 from being pulled and tractioned when the bending angle is too large, thus preventing the copper wire 200 from being damaged by bending.

[0038] Specifically, the position control device 400 includes a position control rod rotatably connected to the twisting disc 800 and a second drive assembly 430 for adjusting the deflection angle of the position control rod. The first guide body 300 is located on the side of the position control rod away from the rotatable connection. The second drive assembly 430 is connected to the first drive assembly 310 for adjusting the deflection angle controlled by the first drive assembly 310. The first drive assembly 310 can adjust the deflection angle of the position control rod, thereby ultimately adjusting the deflection angle of the first guide body 300. By using the position control rod and rotation adjustment, the adjustment range of the first guide body 300 can be expanded, while also effectively preventing the copper wire 200 from being bent and damaged during the adjustment process.

[0039] It should be noted that the second drive component 430 and the first drive component 310 can be adjusted synchronously. When the second drive component 430 drives the position control rod to deflect to the first side, the first drive component 310 can drive the first positioning disk 320 to deflect to the first side; when the second drive component 430 drives the position control rod to deflect to the second side, the first drive component 310 can drive the first positioning disk 320 to deflect to the second side, thus achieving synchronous control when adjusting the twisting angle of the copper wire 200.

[0040] Specifically, refer to the appendix Figure 2 Appendix Figure 4 When the position control lever deflects counterclockwise, the first positioning disk 320 deflects counterclockwise synchronously; when the position control lever deflects clockwise, the first positioning disk 320 deflects clockwise synchronously, which can effectively guide and limit the copper wire 200.

[0041] In summary, through the above structural design, the second drive component 430 can adjust the position control rod to deflect around a predetermined axis, enabling adjustment of the stranding angle of the copper wire 200 at a position far from the stranding disc 800. This adjustment range is large and less restricted by the stranding disc 800 and related structures, allowing for a wide range of stranding angle adjustments. Furthermore, the deflection angle of the first positioning disc 320 can change synchronously with the adjustment of the position control rod's deflection angle, effectively guiding and limiting the copper wire 200 from a distance. This controls the relative consistency of the bending angles of the copper wire 200 on both sides of the first guide body 300, further reducing bending damage to the copper wire 200 during angle adjustment and meeting the requirements for stranding production of different types of copper wires.

[0042] Furthermore, the position control lever includes a first control part 410 and a second control part 420. The first control part 410 and the second control part 420 are fixedly connected and form a predetermined angle between them. The predetermined angle between the first control part 410 and the second control part 420 can be selected as needed, preferably between 60° and 150°, and is specifically determined according to the length relationship between the first control part 410 and the second control part 420 and the range of adjustable hinge angle.

[0043] By setting a predetermined angle between the first control unit 410 and the second control unit 420, when the control rod deflects to the inside, the copper wire 200 can be prevented from contacting the control rod body. The copper wire 200 can be stably pulled and moved within the range of the angle between the two, thus meeting the production requirements of small twisting angles.

[0044] Specifically, both the second drive assembly 430 and the first drive assembly 310 are hydraulic drive assemblies. The second drive assembly 430 and the first drive assembly 310 are connected by a control pipeline, and the flow of oil between the second drive assembly 430 and the first drive assembly 310 can be controlled to achieve synchronous adjustment between the two.

[0045] The second drive assembly 430 is a hydraulic telescopic rod. When the hydraulic telescopic rod extends, it squeezes control oil into the first drive assembly 310, controlling the first drive assembly 310 to drive the first positioning plate 320 to deflect in the first direction. When the hydraulic telescopic rod retracts, it draws out the control oil from the first drive assembly 310, controlling the first drive assembly 310 to drive the first positioning plate 320 to deflect in the second direction. Through the above adjustment method, the angles of the position control rod deflection and the angles of the first positioning plate 320 can be adjusted synchronously while the hydraulic telescopic rod extends and retracts, realizing synchronous linkage between the two, simplifying the internal control structure, and ensuring accurate and fast control.

[0046] The hydraulic telescopic rod here has an arc-shaped cross-section, including an arc-shaped hydraulic base 432. A control piston 433 is slidably connected to the inner wall of the hydraulic base 432. An arc-shaped hydraulic telescopic end 431 is fixed to the side wall of the control piston 433. The hydraulic telescopic end 431 is connected to a position control rod. The control piston 433 divides the hydraulic base 432 into a first control chamber 4301 and a second control chamber 4302. The first control chamber 4301 is connected to the first drive assembly 310, and the second control chamber 4302 is connected to the pumping equipment, thereby realizing the adjustment and control of the position of the control piston 433. Pumping the drive oil into the second control chamber 4302 can push the control piston 433 to move outward, and pumping out the drive oil can attract the control piston 433 to move inward. The second drive assembly 430 can have a built-in elastic reset element to achieve rapid reset.

[0047] The first control chamber 4301 is connected to the first drive assembly 310, and both contain built-in control oil to achieve linkage control. Through the above structural setup, the control oil can be automatically adjusted according to the compression position of the control piston 433, ultimately achieving relative coordination between the extension control of the second drive assembly 430 and the deflection control of the first drive assembly 310. The coordinated adjustment of the two angles is achieved through a pump device, realizing efficient and consistent angle adjustment. While the twisting angle of the copper wire 200 is adjusted, the guide angle of the first positioning plate 320 is quickly and accurately adjusted, ensuring the stability and orderliness of the traction twisting of the copper wire 200.

[0048] An installation notch 810 is provided on the side wall of the stranding disc 800. Inside the installation notch 810, a second guide body 500 and an unwinding device 600 are provided. The second guide body 500 is located between the unwinding device 600 and the first guide body 300. The unwinding device 600 can unwind the long copper wire 200. Here, the second guide body 500 can guide the middle position of the copper wire 200 between the first guide body 300 and the unwinding device 600, so as to avoid the change of the twisting angle of the copper wire 200 from colliding with the surface of the stranding disc 800, and further ensure the stability of the unwinding and twisting of the copper wire 200.

[0049] The second guide body 500 here includes a second positioning disk 530 and two second guide rollers 540. The two second guide rollers 540 are rotatably connected to the second positioning disk 530. A third drive assembly 510 is also provided on the outside of the second positioning disk 530 for adjusting the deflection angle of the second positioning disk 530.

[0050] Similarly, the second guide roller 540 here can be selected with a structure that is concave in the middle and protruding on both sides, which can limit the copper wire 200 in the left and right directions. By setting two second guide rollers 540, the upper and lower sides of the copper wire 200 can be limited, and the copper wire 200 with large twisting angle and small twisting angle can be effectively limited to ensure the stability of the twisting and winding of the copper wire 200.

[0051] The third drive component 510 can adjust the deflection angle of the second positioning disk 530 and the second guide roller 540, and can adaptively adjust the bending state of the copper wire 200 in the middle position, which meets the requirements of bending change during the twisting angle change of the copper wire 200, and further avoids the copper wire 200 bending damage.

[0052] The position control lever is rotatably connected to the winch disc 800 via the mounting base 440. A deflection angle detector 441 is provided on the side wall of the mounting base 440. The deflection angle detector 441 is electrically connected to the third drive assembly 510 to adjust the deflection angle of the second positioning disc 530 controlled by the third drive assembly 510.

[0053] By setting the above structure, the deflection angle of the second positioning disk 530 can be adjusted according to the deflection angle of the position control rod to achieve coordinated control. At this time, the deflection angle of the second positioning disk 530 can be automatically adjusted according to the change in the position of the first guide body 300 at the end, realizing automated control without manual intervention, and with high adjustment efficiency and good adaptability.

[0054] The aforementioned deflection angle detector 441 can be an electrical or optical deflection angle detection element. It detects the magnitude of the deflection angle of the positioning control rod based on the change in resistance or the change in optical sensing, and sends the detected signal to one side of the third drive component 510 to control the third drive component 510 to drive the second positioning disk 530 to deflect towards the predetermined angle.

[0055] The state of copper wire 200 from the attached Figure 2 Small and medium twist angles become attached Figure 4 During the process of medium and large twisting angle, the second positioning disk 530 here deflects clockwise by a predetermined angle (the specific deflection angle is determined according to the distance between the second guide body 500 and the first guide body 300), controlling the two second guide rollers 540 in the middle of the second positioning disk 530 to be able to face the first guide body 300, and adjust the deflection angle as the position of the first guide body 300 changes.

[0056] The second guide body 500 here also includes a hydraulic control joint 520 connected to the second positioning plate 530. The hydraulic control joint 520 is connected to the unwinding device 600 to control the unwinding state of the unwinding device 600.

[0057] The unwinding device 600 here is adjusted and controlled under dual action. With the twisting angle of the copper wire 200 remaining unchanged, the unwinding device 600 can continuously unwind in the left and right directions of the motor, ensuring that the copper wire 200 is always in the predetermined tension state.

[0058] During the process of the stranding angle changing from maximum to minimum, the tension of the copper wire 200 changes from tight to loose and then back to tight. In order to ensure that the copper wire 200 remains in a relatively constant tension state during the change of stranding angle, the unwinding state of the unwinding device 600 can be adjusted by the hydraulic control joint 520. When the copper wire 200 becomes loose, the unwinding device 600 is controlled to partially wind up the copper wire 200, retracting the longer part. When the copper wire 200 becomes tight, the unwinding device 600 is controlled to partially unwind the copper wire 200, controlling the increase of the length of the copper wire 200 between the unwinding device 600 and the stranding head 100. Through the above control method, the tension of the copper wire 200 is kept relatively constant, ensuring that the copper wire 200 can be stranded and wired normally.

[0059] Controlled in the above manner, there is no need to adjust the rotation speed of the motor; it can be unwound at a constant speed. During the change of the twisting angle of the copper wire 200, the unwinding state of the unwinding device 600 can be adjusted by the hydraulic control joint 520, thus achieving adaptive adjustment and control.

[0060] Please refer to the appendix for details. Figure 10 - Appendix Figure 11The unwinding device 600 includes an unwinding body 610 and an unwinding drum 620 sleeved on the outside of the unwinding body 610. An annular hydraulic control groove 640 is formed between the unwinding body 610 and the unwinding drum 620. A first control block 611 located inside the hydraulic control groove 640 is fixed to the side wall of the unwinding body 610. A second control block 621 located inside the hydraulic control groove 640 is fixed to the inner wall of the unwinding drum 620. Both the first control block 611 and the second control block 621 are slidably connected to the hydraulic control groove 640 and a hydraulic control chamber is formed between them. The hydraulic control joint 520 communicates with the hydraulic control chamber.

[0061] The hydraulic control joint 520 can pump control oil into the hydraulic control chamber. By adjusting the amount of oil in the hydraulic control chamber, the positional relationship between the first control block 611 and the second control block 621 can be adjusted, thereby controlling the deflection angle of the unwinding drum 620 relative to the unwinding body 610 and adjusting the unwinding state of the unwinding device 600.

[0062] The unwinding body 610 is connected to the motor to achieve continuous unwinding. The deflection state of the unwinding drum 620 relative to the unwinding body 610 is controlled by the hydraulic control joint 520 to adjust the unwinding and rewinding state of the copper wire 200 and achieve adaptive control.

[0063] After the copper wire 200 is tightened, the control oil in the hydraulic control joint 520 is pumped into the hydraulic control groove 640, where the unwinding drum 620 rotates clockwise to unwind the copper wire 200. Conversely, when the copper wire 200 is slack, the control oil in the hydraulic control groove 640 is drawn out through the hydraulic control joint 520, where the unwinding drum 620 rotates counterclockwise to rewind the copper wire 200. Through the above method, the hydraulic control method can achieve fine adjustment of the unwinding state of the copper wire 200 without affecting the normal unwinding of the copper wire 200, meeting the adjustment and control requirements when adjusting the stranding angle, improving control efficiency, and ensuring the efficiency and quality of copper wire stranding.

[0064] Specifically, a first conveying pipe 612 is provided at the axis of the unwinding body 610, a second conveying pipe 613 is provided on the first side of the first conveying pipe 612 and communicates with the hydraulic control chamber, and a rotating connecting seal 630 is provided on the second side of the first conveying pipe 612 and communicates with the hydraulic control joint 520.

[0065] Through the above structural design, the control oil can enter the first conveying pipe 612 from the outer rotating connection seal 630, and finally enter the hydraulic control tank 640 from the second conveying pipe 613 to achieve adjustment and control. Through the above structural design, while not affecting the normal continuous unwinding of the unwinding body 610, the unwinding drum 620 can be adjusted and controlled to achieve fine adjustment of the unwinding state of the copper wire 200.

[0066] A method for producing copper wire stranding, using the aforementioned copper wire stranding production equipment, includes the following steps:

[0067] S1. Determine the twisting angle between the copper conductor 200 and the main cable 700 according to their specifications. The specifications include the dimensions, material, resistance, and strength of the copper conductor 200 and the main cable 700.

[0068] S2. The first guide body 300 is controlled by the position control device 400 to deflect in a predetermined direction by a predetermined angle, and the twisting angle between the copper wire 200 and the main cable 700 is adjusted to meet the requirements in step S1; at the same time, the first drive component 310 controls the first positioning disk 320 to deflect by a predetermined angle to achieve stable guidance of the copper wire 200.

[0069] The position control device 400 can drive the first guide body 300 to rotate in an arc shape on the side away from the stranding disc 800, which can adjust the stranding angle of the copper wire 200 over a wide range. At the same time, the deflection angle of the first positioning disc 320 can be automatically adjusted as the position of the first guide body 300 changes, controlling the relative consistency of the bending angle of the copper wires 200 on both sides of the first guide body 300, avoiding bending damage of the copper wires 200 under extreme conditions, ensuring normal stranding and winding of the copper wires 200, and meeting the requirements under different conditions.

[0070] This invention is illustrated using the example of twisted and wired copper conductors. Those skilled in the art can twist and wired conductors of different materials without departing from the concept of this invention.
