Abstract
Description
Technical Field
[0001] This application relates to the technical field of copper conductor processing equipment, and in particular to a tension adjustment device for continuous pulling and unpulling of copper conductor cables. Background Technology
[0002] During the continuous drawing and unwinding process of copper conductor cables, the stability of the tension directly affects the dimensional accuracy, surface quality, and mechanical properties of the cable. If the tension is too high, the cable is easily pulled thin, breaks, or even undergoes excessive plastic deformation. If the tension is too low, the cable will become loose and deviate during processing, affecting the subsequent annealing effect and the neatness of the winding.
[0003] In existing technologies, tension adjustment in continuous drawing and undrawing production lines for copper conductor cables mostly adopts passive adjustment structures, such as applying preload to the guide wheel through a weight or spring assembly, and using the tension change of the cable to drive the guide wheel to move and achieve tension buffering. However, such passive adjustment methods have slow response speeds and are difficult to adapt to rapid tension fluctuations caused by factors such as changes in cable travel speed and wear of the drawing die. The adjustment accuracy is low and cannot meet the processing requirements of high-precision copper conductor cables. Therefore, a continuous drawing and undrawing tension adjustment device for copper conductor cables is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a tension adjustment device for copper conductor cables that allows for continuous pulling and unpulling, in order to solve the problems mentioned in the background art.
[0005] The copper conductor cable tension adjustment device provided in this application adopts the following technical solution:
[0006] A tension adjustment device for copper conductor cables that allows for continuous pulling and unpulling includes a mounting plate. A tension detection component is mounted on the outer wall of the mounting plate. The tension detection component includes a tension sensor and a detection guide wheel. The fixed end of the tension sensor is fixedly connected to the outer wall of the mounting plate by screws, and its force-bearing end is fixedly connected to a bracket. The detection guide wheel is rotatably connected to the outer wall of the bracket.
[0007] An active adjustment assembly is installed on the outer wall of the mounting plate, which includes a servo electric cylinder, a tensioning wheel one, and a tensioning wheel two. The servo electric cylinder is fixedly installed on the outer wall of the mounting plate, and its output end is fixedly connected to a bracket one. The tensioning wheel one is rotatably connected to the outer wall of the bracket one, and the tensioning wheel two and the tensioning wheel one are distributed alternately in an up-down manner.
[0008] Preferably, the active adjustment assembly further includes a drive arm, a pivot pin, and a slider. The middle section of the outer wall of the drive arm is rotatably connected to the outer wall of the mounting plate. Two movable slots are symmetrically formed on the outer wall of the drive arm, and the two pivot pins are movably connected to the inner walls of the two movable slots.
[0009] Preferably, the outer wall of the mounting plate has two grooves, the two sliders are slidably connected to the inner walls of the two grooves, the tensioning wheel is rotatably connected to the outer wall of one of the sliders, and the bracket is fixedly connected to the outer wall of the other slider.
[0010] Preferably, the outer wall of the mounting plate is further equipped with multiple sets of guide components. Each set of guide components includes fixed wheels and movable wheels. Multiple fixed wheels are rotatably connected to the outer wall of the mounting plate, and multiple movable wheels are rotatably connected to the outer wall of the mounting plate. The movable wheels are located directly above the fixed wheels.
[0011] Preferably, each set of guide components further includes a fixed plate, a guide rod, and a spring. The multiple fixed plates are fixedly connected to the outer wall of the mounting plate and located above the movable wheel. The guide rod is slidably connected to the inner wall of the fixed plate, and its bottom end is fixedly connected to the connector.
[0012] Preferably, the spring is sleeved on the outer wall of the guide rod, with its top end abutting against the fixing plate and its bottom end abutting against the top outer wall of the connector.
[0013] Preferably, the outer wall of the mounting plate has multiple mounting holes, which are evenly distributed at the four corners of the mounting plate.
[0014] In summary, this application includes the following beneficial technical effects:
[0015] A closed-loop control system is constructed by using a tension sensor, external control equipment, and a servo cylinder. The tension sensor captures the tension changes of the copper conductor cable in real time and transmits the signal. The external control equipment quickly analyzes and judges the signal and sends adjustment commands to the servo cylinder. With the linkage structure of the drive arm and the slider, the tension wheel is adjusted synchronously and in reverse with precision. This effectively solves the problems of slow response speed and low accuracy of the existing passive adjustment method. It can quickly adapt to tension fluctuations caused by factors such as changes in cable travel speed and wear of the wire drawing die. It avoids problems such as cable thinning, breakage, and excessive plastic deformation caused by excessive tension, as well as problems such as cable slack, deviation, poor annealing effect, and poor winding regularity caused by insufficient tension. It significantly improves the dimensional accuracy, surface quality, and mechanical properties of copper conductor cables and can meet the processing requirements of high-precision copper conductor cables.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0021] This application discloses a tension adjustment device for copper conductor cables that allows for continuous pulling and unpulling. (Refer to...) Figure 1-3 The tension adjustment device for continuous pulling and unpulling of copper conductor cables includes a mounting plate 1, which is a basic support structure. The outer wall of the mounting plate 1 is integrated with tension detection components, active adjustment components and multiple sets of guide components. Multiple mounting holes 20 are opened at the four corner edges of the mounting plate 1 for fixing the device as a whole to the frame of the continuous pulling and unpulling production line by fasteners.
[0022] The tension detection assembly is installed on the outer wall of the mounting plate 1 and consists of a tension sensor 10, a bracket 11, and a detection guide wheel 12. The fixed end of the tension sensor 10 is fixedly connected to the outer wall of the mounting plate 1 with screws, while the force-bearing end of the tension sensor 10 is fixedly connected to the bracket 11. The detection guide wheel 12 is rotatably connected to the outer wall of the bracket 11 via a bearing. A copper conductor cable can be wound around the groove of the detection guide wheel 12 to realize the real-time transmission and detection of tension. It should be noted that the tension sensor 10 is electrically connected to an external control device via a signal line, which can convert the sensed tension mechanical signal into an electrical signal and transmit it to the external control device in real time, providing data for tension adjustment. This is existing technology and will not be described in detail.
[0023] The active adjustment assembly includes a servo electric cylinder 19, tension wheel 1 7, tension wheel 2 9, drive arm 4, shaft pin 6, slider 3, bracket 1 8, and related auxiliary structures.
[0024] Servo electric cylinder 19 is fixedly installed on the outer wall of mounting plate 1, and its output end is fixedly connected to bracket 8. Tensioning wheel 7 is rotatably connected to the outer wall of bracket 8 through bearing. Tensioning wheel 9 is staggered with tensioning wheel 7, and tensioning wheel 9 is rotatably connected to the outer wall of one of the sliders 3 through bearing. Bracket 8 is fixedly connected to the outer wall of the other slider 3.
[0025] Two grooves 2 are provided on the outer wall of the mounting plate 1. Two sliders 3 are slidably connected to the inner walls of the two grooves 2 respectively, and can move back and forth along the extension direction of the grooves 2. The middle section of the outer wall of the drive arm 4 is rotatably connected to the outer wall of the mounting plate 1 through a rotating shaft, so that the drive arm 4 can rotate around the rotating shaft. Two movable grooves 5 are symmetrically provided on the outer wall of the drive arm 4. Two shaft pins 6 are movably connected to the inner walls of the two movable grooves 5 respectively, and the ends of the two shaft pins 6 away from the movable grooves 5 are fixedly connected to the two sliders 3 respectively, realizing the linkage between the drive arm 4 and the sliders 3. It should be noted that the servo electric cylinder 19 is electrically connected to the external control device through the control line, and can receive the action command issued by the external control device to drive the output end to perform telescopic movement. This is the prior art and will not be described in detail.
[0026] Multiple sets of guide components are installed on the outer wall of the mounting plate 1. Each set of guide components is distributed at intervals along the travel path of the copper conductor cable. Each set of guide components includes a fixed wheel 13, a movable wheel 14, a connector 15, a fixing plate 16, a guide rod 17, and a spring 18.
[0027] The fixed wheel 13 is rotatably connected to the outer wall of the mounting plate 1 via a bearing. The movable wheel 14 is located directly above the fixed wheel 13. The outer wall of the movable wheel 14 is rotatably connected to the connector 15 via a bearing. The fixed plate 16 is fixedly connected to the outer wall of the mounting plate 1 and is located above the movable wheel 14. The guide rod 17 is slidably connected to the inner wall of the fixed plate 16, and its bottom end is fixedly connected to the connector 15. The spring 18 is sleeved on the outer wall of the guide rod 17. The top end of the spring 18 abuts against the fixed plate 16, and the bottom end abuts against the top outer wall of the connector 15. Under the elastic force of the spring 18, the movable wheel 14 can always keep in contact with the copper conductor cable.
[0028] The implementation principle of the copper conductor cable tension adjustment device in this application embodiment is as follows: When the device is working, the copper conductor cable passes through the inlet side guide component, tension detection component, active adjustment component and outlet side guide component in sequence. In the inlet side and outlet side guide components, the movable wheel 14 presses the cable under the action of the spring 18, and cooperates with the fixed wheel 13 to limit the cable's travel trajectory and reduce deviation.
[0029] In the tension detection assembly, the detection guide wheel 12 generates force as the cable tension changes. The tension sensor 10 senses the tension and transmits a signal. When the tension is abnormal, the servo cylinder 19 drives the bracket 8 to move, causing one side slider 3 to slide along the slide groove 2. The slider 3 drives the drive arm 4 to rotate through the shaft pin 6. The drive arm 4 drives the other slider 3 to slide synchronously through the other shaft pin 6, causing the tension wheel 7 and the tension wheel 9 to move in opposite directions, changing the cable wrap angle and tension, and realizing tension adjustment. During the adjustment process, the slider 3 slides along the slide groove 2 to ensure motion stability, and the drive arm 4 ensures that the two sliders 3 are linked and synchronized, improving the adjustment accuracy and efficiency.
