Description

Technical Field

[0001] This application relates to the field of copper conductor processing equipment technology, and in particular to a traction device for continuous pulling and annealing of copper conductor cables. Background Technology

[0002] In the production and processing of copper conductor cables, the continuous stretching and annealing process is one of the key steps. It involves continuously stretching the copper conductor to achieve the required diameter and simultaneously annealing it to eliminate work hardening, thus ensuring the conductivity and mechanical properties of the cable. The traction device, as the core equipment in this process, is responsible for driving the copper conductor cable through the stretching die and annealing furnace continuously. Its working stability directly affects the processing accuracy and product quality of the cable.

[0003] Existing copper conductor cable traction devices mostly adopt simple roller clamping traction structures, which have the following shortcomings: First, the clamping force adjustment accuracy of the cable is low. When processing cables of different diameters, it is difficult to quickly adjust to the appropriate clamping force. If the clamping is too loose, the cable will slip, affecting the stability of the traction speed. If the clamping is too tight, it may cause damage or deformation to the cable surface. Therefore, a traction device for continuous pulling and annealing of copper conductor cables is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a traction device for continuous pulling and annealing of copper conductor cables, so as to solve the problems mentioned in the background art.

[0005] The traction device for continuous pulling and annealing of copper conductor cables provided in this application adopts the following technical solution:

[0006] A traction device for continuous pulling and annealing of copper conductor cables includes a mounting plate. A traction assembly is installed on the outer wall of the mounting plate. The traction assembly includes a movable plate and a plurality of traction wheels. Two movable plates are symmetrically distributed vertically. The plurality of traction wheels are rotatably connected to the outer walls of the two movable plates at equal intervals.

[0007] A detection assembly is installed on the outer wall of a movable plate located above. The detection assembly includes a pressure sensor and a movable block. The pressure sensor is slidably connected to the inner wall of the middle section of the movable plate. The fixed end of the pressure sensor is fixedly connected to the inner wall of the top of the movable plate, and the force-bearing end is fixedly connected to the top of the movable block. One of the traction wheels is rotatably connected to the outer wall of the movable block.

[0008] Preferably, a traction motor is fixedly installed on the outer wall of the middle section of one of the lower movable plates, and the output shaft of the traction motor is fixedly connected to the axle of one of the traction wheels.

[0009] Preferably, the traction assembly further includes multiple sliders, a bidirectional lead screw, and a stepper motor. Each pair of sliders is fixedly connected to the outer walls of both ends of a movable plate via a connecting post, and a connecting plate is fixedly connected to the outer walls of each pair of sliders.

[0010] Preferably, the two ends of the bidirectional lead screw are rotatably connected to the outer wall of the mounting plate via bearing seats, and the inner walls of the middle sections of the two connecting plates are threaded to the outer wall of the bidirectional lead screw.

[0011] Preferably, the stepper motor is fixedly mounted on the outer wall of the mounting plate by a bracket, and the end of the output shaft of the stepper motor is fixedly connected to the bottom end of the bidirectional lead screw.

[0012] Preferably, the outer wall of the mounting plate has two sliding grooves, and the plurality of sliders are slidably connected to the inner walls of the two sliding grooves respectively. The bidirectional lead screw is located between the two sliding grooves and is arranged parallel to the two sliding grooves.

[0013] Preferably, a guide assembly is installed on the outer wall of the mounting plate near the left side, which includes a guide wheel one, a guide wheel two, and a connecting frame. The guide wheel one and the guide wheel two are symmetrically distributed vertically. The guide wheel two is rotatably connected to the outer wall of the mounting plate, while the guide wheel one is rotatably connected to the inner wall of the connecting frame.

[0014] Preferably, the guide assembly further includes a fixed plate, a slide rod, and a spring.

[0015] Preferably, the outer wall of the mounting plate is rotatably connected to multiple tensioning rollers.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] By combining a traction component with precisely adjustable spacing with a detection component that monitors clamping force in real time, the problem of low precision in adjusting cable clamping force in existing roller clamping traction structures is effectively solved. This not only allows for quick adaptation to the clamping requirements of cables of different diameters, avoiding cable slippage due to excessively loose clamping that affects the stability of traction speed, but also prevents surface damage or deformation of the cable due to excessively tight clamping. At the same time, the guide and tensioning structure further ensures the stability of the traction process, significantly improving the quality and efficiency of continuous drawing and annealing processing of copper conductor cables.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a traction device for continuous pulling and annealing of copper conductor cables. (Refer to...) Figure 1-4 A traction device for continuous pulling and annealing of copper conductor cables includes a mounting plate 1. The mounting plate 1 is made of metal and has a flat outer wall with reserved assembly positions for installing traction components, detection components and guiding components. The mounting plate 1 can be fixed to the designated position of the continuous pulling and annealing production line by bolts to ensure that the whole device is compatible with the feed end of the production line and the outlet position of the annealing furnace, and to provide stable support for the coordinated work of each component.

[0025] The traction assembly includes two movable plates 10 and multiple traction wheels 11. The two movable plates 10 are symmetrically distributed vertically and both mate with the outer wall of the mounting plate 1. Each movable plate 10 has axle mounting holes machined along its length on its outer wall. The multiple traction wheels 11 are rotatably connected to the axle mounting holes via axles, and a clamping traction channel is formed between the upper and lower corresponding traction wheels 11 for the copper conductor cable to pass through. The upper and lower traction wheels 11 respectively abut against the outer wall of the cable from the upper and lower sides, limiting the cable through clamping force to ensure that the cable does not deviate during traction, while providing driving force for the cable movement.

[0026] The traction assembly also includes multiple sliders 9, a bidirectional lead screw 16, and a stepper motor 17. Each pair of sliders 9 forms a group, and the two groups of sliders 9 are respectively fixed to the outer walls of the two ends of the two moving plates 10 through connecting columns. The connecting columns are welded to the moving plates 10 and sliders 9 to ensure connection strength. The two sliders 9 at both ends of the same moving plate 10 are fixedly connected to the outer wall away from the moving plate 10 by a connecting plate 15. The connecting plate 15 is a sheet structure perpendicular to the moving plate 10, and a threaded hole is machined in the middle section for cooperating with the bidirectional lead screw 16.

[0027] The bidirectional lead screw 16 is set along the height direction of the mounting plate 1. Both ends of the bidirectional lead screw 16 are rotatably connected to the outer wall of the mounting plate 1 through seated bearings. The seated bearings are fixed to the mounting plate 1 by bolts to ensure the stability of the bidirectional lead screw 16 when rotating. The threaded holes of the two connecting plates 15 are respectively adapted to the upper and lower reverse threads of the bidirectional lead screw 16, and the two connecting plates 15 are respectively threaded to the upper and lower reverse thread areas of the bidirectional lead screw 16. When the bidirectional lead screw 16 rotates clockwise or counterclockwise, it can drive the two connecting plates 15 to move closer or further away synchronously, thereby driving the two moving plates 10 to move closer or further away synchronously, realizing the adjustment of the clamping traction channel spacing to adapt to copper conductor cables of different diameters.

[0028] The stepper motor 17 is fixedly mounted on the outer wall of the mounting plate 1 by a bracket. One end of the bracket is welded to the mounting plate 1, and the other end is fixed to the stepper motor 17 by bolts to ensure that the stepper motor 17 has no displacement when it is working. The output shaft axis of the stepper motor 17 is collinear with the axis of the bidirectional lead screw 16. The end of the output shaft of the stepper motor 17 is fixedly connected to the bottom end of the bidirectional lead screw 16 by a coupling. The forward and reverse rotation of the stepper motor 17 precisely drives the bidirectional lead screw 16 to rotate, thereby precisely adjusting the distance between the two moving plates 10, providing a structural basis for the precise control of the clamping force.

[0029] Two parallel sliding grooves 8 are formed on the outer wall of the mounting plate 1 along the height direction. The two sliding grooves 8 are located on both sides of the bidirectional lead screw 16. The ends of multiple sliders 9 away from the moving plate 10 are machined with protrusions that are adapted to the sliding grooves 8. The protrusions of the sliders 9 are slidably embedded in the inner wall of the sliding grooves 8 to form a sliding guide fit. When the moving plate 10 moves under the drive of the bidirectional lead screw 16, the sliders 9 slide smoothly along the sliding grooves 8 to avoid the moving plate 10 tilting or jamming, and to ensure that the upper and lower moving plates 10 always remain parallel. This ensures that the clamping force of the upper and lower traction wheels 11 on the cable is uniform and there is no situation where the clamping is too tight or too loose in some areas.

[0030] A traction motor 14 is fixedly mounted on the outer wall of the middle section of a lower movable plate 10 via a bracket. One end of the bracket is welded to the movable plate 10, and the other end is fixed to the traction motor 14 with bolts. The output shaft of the traction motor 14 is fixedly connected to the shaft of one of the traction wheels 11 on the lower movable plate 10 via a coupling. This traction wheel 11 is the active traction wheel, and the other traction wheels 11 are the driven traction wheels. After the traction motor 14 is started, it drives the active traction wheel to rotate. The friction between the active traction wheel and the cable drives the cable to move along the traction direction. At the same time, the driven traction wheels rotate synchronously with the cable to assist in stabilizing the traction. The driving force of the active traction wheel and the clamping force of the upper and lower traction wheels 11 on the cable work together to ensure that the cable moves at a uniform speed and stably, avoiding slippage.

[0031] The detection component is installed on the outer wall of a movable plate 10 located above. Its core function is to detect the clamping force of the upper and lower traction wheels 11 on the copper conductor cable in real time. It includes a pressure sensor 12 and a movable block 13. The middle section of the inner wall of the upper movable plate 10 is provided with a mounting groove adapted to the sliding of the movable block 13. The outer wall of the movable block 13 fits against the inner wall of the mounting groove and can slide vertically along the mounting groove to ensure that the movable block 13 can move flexibly with the change of clamping force.

[0032] Pressure sensor 12 is embedded in the middle inner wall of movable plate 10. The fixed end of pressure sensor 12 is fixedly connected to the top inner wall of the mounting groove of movable plate 10 by bolts. The force detection end of pressure sensor 12 is fixedly connected to the top of movable block 13. The displacement of movable block 13 can be directly transmitted to the force-receiving end of pressure sensor 12. One of the traction wheels 11 is rotatably connected to the outer wall of movable block 13 facing downward movable plate 10 through a rotating shaft. The traction wheel 11 and the corresponding traction wheel 11 on the lower movable plate 10 together clamp the cable.

[0033] When the upper and lower moving plates 10 approach each other and clamp the cable through the traction wheel 11, the cable generates an upward reaction force on the traction wheel 11 on the upper movable block 13. This reaction force pushes the movable block 13 to move upward along the mounting groove, thereby generating pressure on the force detection end of the pressure sensor 12. The pressure sensor 12 converts the pressure signal into an electrical signal and transmits it to the external control system to realize the real-time detection and feedback of the cable clamping force. The operator can intuitively obtain the current clamping force through the control system. If the force is too large (may damage the cable) or too small (may cause slippage), the distance between the moving plates 10 can be adjusted by adjusting the stepper motor 17 until the clamping force reaches the appropriate value.

[0034] The guide assembly is installed on the outer wall near the left side of the mounting plate 1 to guide the cable precisely into the clamping and traction channel. It includes guide wheel 1 2, guide wheel 2 3 and connecting frame 4. Guide wheel 1 2 and guide wheel 2 3 are symmetrically distributed vertically and are used to guide the cable before traction to prevent the cable from deviating. Guide wheel 2 3 is rotatably connected to the outer wall of the left side of the mounting plate 1. The connecting frame 4 has a U-shaped structure and a wheel axle hole is machined on the inner wall of its open end. Guide wheel 1 2 is rotatably connected to the wheel axle hole through a rotating shaft to ensure that guide wheel 1 2 can rotate flexibly with the cable and reduce friction damage between the cable and the guide wheel.

[0035] The guide assembly also includes a fixed plate 5, a slide rod 6, and a spring 7, which are used to adapt to the guiding requirements of cables of different diameters and to buffer the tension fluctuations when the cable is input. The fixed plate 5 is a horizontal sheet structure, which is fixedly connected to the outer left wall of the mounting plate 1 by bolts. The fixed plate 5 is located above the second guide wheel 3. The middle section of the fixed plate 5 is machined with a sliding hole. The slide rod 6 slides vertically through the sliding hole. The bottom end of the slide rod 6 passes through the fixed plate 5 and is welded and fixed to the top of the closed end of the connecting frame 4. The slide rod 6 can drive the connecting frame 4 and the first guide wheel 2 to move up and down synchronously.

[0036] Spring 7 is sleeved on the outer wall of slide rod 6. The top of spring 7 abuts against the bottom of fixed plate 5, and the bottom of spring 7 abuts against the top of closed end of connecting frame 4. Spring 7 is always in a pre-compressed state. The pre-compressed spring 7 pushes connecting frame 4 and guide wheel 2 downward through elastic force, so that guide wheel 2 is always in close contact with the outer wall of cable. When the cable diameter changes, guide wheel 2 can adjust its position up and down with the extension and retraction of spring 7 to ensure that guide wheel 2 and guide wheel 3 always form a stable guide for cable. At the same time, the elastic force of spring 7 can buffer the sudden tension change when cable is input, and avoid the cable clamping force being unstable due to tension fluctuation.

[0037] The outer wall of the mounting plate 1 is connected to multiple tensioning wheels 18 by a wheel frame. The wheel frame is welded or bolted to the mounting plate 1, and the multiple tensioning wheels 18 are located between the traction component and the guide component, forming a transition tensioning channel for the cable from the guide component to the traction component. After the cable is led out from between the guide wheel 2 and the guide wheel 3 of the guide component, it first passes around the multiple tensioning wheels 18 and then enters the clamping traction channel of the traction component.

[0038] The implementation principle of the traction device for continuous pulling and annealing of copper conductor cables in this embodiment is as follows: The copper conductor cable is led out from the feed end of the production line. After the cable is led out between the guide wheel 2 and the guide wheel 3 of the guide assembly, it first passes around multiple tension wheels 18, then enters the clamping traction channel of the traction assembly, and finally enters the annealing furnace. According to the cable diameter, the stepper motor 17 is started to drive the bidirectional lead screw 16 to rotate, which drives the two connecting plates 15 and the moving plate 10 to move closer to each other synchronously until the upper and lower traction wheels 11 are in contact with the outer wall of the cable. At this time, the pressure sensor 12 of the detection assembly detects the clamping force signal and transmits it to the control system. The operator fine-tunes the stepper motor 17 according to the signal feedback until the clamping force reaches the appropriate value.

[0039] The traction motor 14 is started, driving the drive traction wheel 11 on the lower moving plate 10 to rotate. The friction between the drive traction wheel 11 and the cable drives the cable to move along the traction direction. The follower traction wheel 11 rotates synchronously with the cable to assist in stabilizing the traction. During the traction process, the pressure sensor 12 continuously detects the clamping force and feeds it back to the control system. If the clamping force is too large, the control system controls the stepper motor 17 to drive the moving plate 10 slightly away to reduce the force; if the clamping force is too small, the control system controls the moving plate 10 to move slightly closer to increase the force, ensuring that the clamping force is always stable. When the cable is input, the spring 7 of the guide component pushes the guide wheel 2 to press against the cable, guiding the cable to accurately enter the clamping traction channel and preventing the cable from deviating.
