Description

TECHNICAL FIELD

[0001] The present application relates to the field of metal wire drawing processing and industrial automation, and in particular to a copper wire multi-head drawing tension intelligent adjustment method and system. BACKGROUND

[0002] The copper wire drawing process is an important basic process in the field of metal wire processing, and is widely used in the manufacturing process of products such as wire and cable, electronic components, automobile wiring harness, and precision connectors. With the increasing requirements of downstream applications for copper wire diameter consistency, surface quality, and mechanical properties, multi-head drawing and continuous drawing have become important technical means to improve production efficiency and reduce manufacturing costs.

[0003] In existing multi-head drawing equipment, copper wire is processed by gradually reducing the diameter through multiple drawing heads or multi-pass drawing dies. In this process, drawing tension is one of the key process parameters that affect the quality of the finished copper wire. If the tension is too high, it can cause the copper wire to break, surface cracks, or internal stress concentration. If the tension is too low, it can cause slipping, diameter fluctuations, and unstable drawing, which can affect product consistency and production continuity.

[0004] In the prior art, multi-head drawing tension control is usually set by experience or single-point detection. Typically, only the overall drawing speed or the speed of a certain drawing head is simply adjusted, making it difficult to accurately reflect the tension distribution between each drawing head and each drawing pass. When the copper wire specification changes, the material properties fluctuate, or the equipment operating state changes, the existing control method responds slowly and cannot achieve synchronized and fine adjustment of the tension of each drawing head, which can cause tension imbalance and affect the quality of the finished product and the stable operation of the equipment.

[0005] In addition, existing multi-head drawing tension adjustment systems generally lack comprehensive analysis of multi-source operating parameters, making it difficult to effectively integrate tension data with parameters such as wire speed, motor speed, and wire diameter changes. They also lack a closed-loop intelligent adjustment mechanism based on real-time feedback, frequent manual intervention, low automation and intelligence, and are not conducive to achieving efficient, continuous, and high-consistency drawing production.

[0006] Therefore, there is an urgent need for a copper wire multi-head drawing tension intelligent adjustment method and system that can real-time perceive, intelligently analyze, and closed-loop adjust the tension of each drawing head for multi-head drawing conditions, to solve the problems of insufficient tension control precision, slow adjustment response, and poor stability in the prior art. SUMMARY

[0007] To improve the low tension control precision, poor stability, frequent manual intervention, and difficulty in adapting to changes in copper wire specifications and working conditions in the prior art, the present application provides a copper wire multi-head drawing tension intelligent adjustment method and system.

[0008] The copper wire multi-head drawing tension intelligent adjustment method and system provided by the application adopts the following technical scheme: In a first aspect, a copper wire multi-head drawing tension intelligent adjustment method is applied to a multi-head drawing device, and includes the following steps: Step one: real-time collection of drawing tension data of corresponding copper wires at each drawing head and / or each drawing pass of the multi-head drawing device; Step two: synchronous collection of line speed, motor speed and line diameter change parameters corresponding to each drawing head; Step three: fusion analysis of the collected tension data and operating parameters to construct a multi-head drawing tension distribution model; Step four: calculation of a target tension interval corresponding to each drawing head according to copper wire specification parameters and preset drawing process parameters; Step five: generation of a tension adjustment instruction when it is detected that the actual tension deviates from the target tension interval; Step six: adjustment of the driving motor speed and / or drawing speed of the corresponding drawing head according to the tension adjustment instruction; Step seven: feedback of the adjusted tension state to the control system to form a closed-loop control and realize intelligent stable adjustment of the multi-head drawing tension.

[0009] By adopting the above technical scheme, the copper wire multi-head drawing tension intelligent adjustment method can realize real-time, comprehensive and fine control of the tension state of each drawing head and each drawing pass during multi-head drawing. Through synchronous collection and fusion analysis of multiple parameters such as drawing tension, line speed, motor speed and line diameter change, a multi-head drawing tension distribution model is constructed, so that the tension matching relationship between each drawing head and between adjacent passes is clearer and more controllable. On this basis, a target tension interval is dynamically calculated according to the copper wire specification and drawing process parameters, and an adjustment instruction is generated in time when the actual tension deviates from the target range to accurately adjust the driving motor speed and the drawing speed, forming a rapid response closed-loop control mechanism. This method can effectively overcome the problems of tension adjustment relying on manual experience, response lag and insufficient stability in the prior art, improve the uniformity and consistency of tension control during multi-head drawing, and reduce the occurrence of quality problems such as broken wires, surface defects and size fluctuations. At the same time, this method has good self-adaptive ability, can adapt to different copper wire specifications and working condition changes, reduces the frequency of manual intervention, improves the automation level, product yield and overall production efficiency of the production process.

[0010] Optionally, the tension data is collected in real time by a tension sensor arranged at each drawing head.

[0011] By adopting the above technical solution, tension sensors are installed at each drawing head to collect tension data in real time. This allows for direct and accurate acquisition of the actual force state corresponding to each drawing head, enabling highly sensitive monitoring of tension changes in multi-head drawing. It also allows for timely detection of tension fluctuations or abnormalities, providing a reliable data basis for subsequent tension analysis and adjustment, improving the accuracy and response speed of tension control, and enhancing the stability and consistency of the multi-head drawing process.

[0012] Optionally, the tension distribution model is used to characterize the tension matching relationship between each drawing head and between adjacent drawing passes.

[0013] By adopting the above technical solution, a tension distribution model is constructed to characterize the tension matching relationship between each drawing head and between adjacent drawing passes. This model can systematically reflect the tension transmission and coupling characteristics during multi-head drawing, avoiding the tension imbalance problem caused by independent adjustment of a single drawing head. This model helps to achieve overall coordinated control, keeping the tension of each drawing head consistent, thereby reducing the risk of wire breakage and improving drawing quality and production stability.

[0014] Optionally, the target tension range is dynamically set based on the copper wire diameter, material properties, and wire reduction rate.

[0015] By adopting the above technical solution, the target tension range is dynamically set according to the copper wire diameter, material properties and wire drawing reduction rate, so that the tension control parameters can be adjusted in real time according to the working conditions. This avoids the control deviation caused by using a fixed tension threshold, and helps to take into account the stress requirements of copper wires of different specifications at each drawing stage, preventing over-tension or under-tension problems, thereby improving the adaptability, stability and finished product consistency of the drawing process.

[0016] Optionally, the tension adjustment command includes a drive motor speed adjustment command, a pay-off speed adjustment command, or a take-up speed adjustment command.

[0017] By adopting the above technical solution, the drawing tension can be precisely controlled from multiple execution dimensions, enabling rapid response and fine adjustment to tension changes. This effectively avoids the control lag problem caused by a single adjustment method, thereby improving the flexibility, stability and adjustment accuracy of tension control during multi-head drawing.

[0018] Optionally, when an abnormal tension is detected, the method further includes the steps of issuing an alarm signal and recording abnormal operating data.

[0019] By adopting the above technical solutions, operators can be informed of abnormal equipment conditions in a timely manner, preventing wire breakage, equipment damage, or product scrap due to uncontrolled tension. At the same time, the recorded abnormal data can be used for subsequent fault analysis and process optimization, improving the safety, traceability, and long-term stability of the multi-head wire drawing system.

[0020] Secondly, a copper wire multi-head drawing tension intelligent adjustment system includes: A multi-point tension acquisition module is used to acquire the wire drawing tension data corresponding to each wire drawing head in the multi-head wire drawing equipment in real time. The operating parameter acquisition module is used to acquire parameters such as linear velocity, motor speed, and wire diameter variation. The data processing and analysis module is used to fuse tension data and operating parameters and construct a multi-head drawing tension distribution model. The intelligent decision control module is used to generate tension adjustment commands based on the target tension range; An execution control module is used to adjust the drive device of each drawing head according to the tension adjustment command; A feedback control module is provided to feed back the adjusted tension state to the intelligent decision control module to form a closed-loop control.

[0021] By adopting the above technical solution, the tension state, linear speed, motor speed, and wire diameter changes of each drawing head during the multi-head wire drawing process are synchronously and in real time acquired. The data processing and analysis module performs fusion modeling, which can comprehensively reflect the tension distribution and dynamic change characteristics of the multi-head wire drawing system. The intelligent decision control module automatically generates adjustment commands based on the target tension range, and the execution control module precisely adjusts the operating status of each drawing head drive device. At the same time, combined with the feedback control module, a closed-loop control system is formed to achieve rapid correction of tension deviation. This system can effectively solve the problems of inconsistent tension, large fluctuations, and adjustment lag during multi-head wire drawing, improve the stability of the wire drawing process, the consistency of the finished wire diameter, and production efficiency, reduce the risk of wire breakage, and is suitable for continuous and intelligent copper wire drawing production scenarios.

[0022] Optionally, the multi-point tension acquisition module includes tension sensors disposed at each drawing head; The execution control module includes a frequency converter, a servo driver, and / or an electromagnetic braking device.

[0023] By adopting the above technical solutions, the tension status of each drawing head can be collected in real time and accurately, providing a reliable data foundation for tension analysis and adjustment. At the same time, the execution control module uses a frequency converter, a servo driver and / or an electromagnetic braking device, which can quickly and precisely adjust the speed and braking force of the drive motor, making the tension adjustment response more timely and the control more stable, effectively improving the tension control accuracy of multi-head drawing and reducing tension fluctuations and the risk of wire breakage.

[0024] Optionally, the intelligent decision control module calculates the tension adjustment strategy based on preset wire drawing process parameters and historical operating data.

[0025] By adopting the above technical solutions, the tension adjustment strategy is made more in line with the actual working condition changes, improving the foresight and adaptability of control decisions; it can quickly provide reasonable adjustment solutions when working conditions fluctuate or material properties change, reducing reliance on manual experience and improving the stability and consistency of tension control.

[0026] Optionally, the system also includes a human-machine interaction module for displaying the real-time tension status and alarm information of each wire drawing head; The system is suitable for online continuous wire drawing processes, and the copper wire after adjustment can directly enter the subsequent processing steps.

[0027] By adopting the above technical solution, the human-machine interaction module can visualize the real-time tension status and alarm information of each drawing head, making it easy for operators to intuitively grasp the equipment operation status and intervene in abnormalities in a timely manner. At the same time, the system is suitable for online continuous drawing processes, so that tension adjustment can be seamlessly connected with subsequent processing steps, reducing intermediate downtime and manual adjustment time, and improving production continuity, automation level and overall processing efficiency.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. By simultaneously collecting multi-source data such as tension, linear speed, motor speed and wire diameter changes at each drawing head and / or each drawing pass, and performing fusion analysis, the tension distribution state during the multi-head drawing process can be comprehensively and in real time reflected, realizing refined perception and control of tension changes, and achieving real-time and refined control of multi-head drawing tension; 2. By constructing a multi-head drawing tension distribution model and introducing target tension range control, the tension matching relationship between each drawing head and between adjacent drawing passes is made more coordinated, significantly reducing tension fluctuations and inconsistencies, reducing wire breakage, jitter and quality fluctuations, and improving the consistency and stability of multi-head drawing tension; 3. When the tension deviates from the target range, the system can automatically generate adjustment commands and adjust the drive motor speed, wire release speed or wire take-up speed in real time. At the same time, the adjustment results are fed back to the control system to build closed-loop control, which effectively overcomes the problems of slow response and insufficient stability of manual adjustment. 4. The target tension range is dynamically set based on the copper wire diameter, material properties and wire drawing reduction rate, and the adjustment strategy is calculated in combination with historical operating data, so that the system can adapt to different specifications of copper wire and changes in working conditions, thereby improving process flexibility and operational reliability. 5. Through intelligent decision control and automatic execution adjustment, the reliance on human experience is significantly reduced, the labor intensity of operators and human error are reduced, and the automation and intelligence of multi-head wire drawing production lines are improved; 6. Stable and uniform tension control helps improve the consistency of copper wire diameter and surface quality, reduce defective products and rework rate, and supports online continuous wire drawing process, which can be seamlessly connected with subsequent processing steps, thereby significantly improving overall production efficiency and finished product yield.

[0029] 7. When abnormal tension is detected, the system can promptly alarm and record abnormal operating data, facilitating quick handling by operators. It also provides data support for subsequent fault analysis and process optimization, improving the safety and maintainability of system operation, and enhancing the safety and traceability of system operation.

[0033] This application discloses a method and system for intelligent tension adjustment in multi-head copper wire drawing. (Refer to...) Figure 1 A method for intelligent tension adjustment in multi-head copper wire drawing includes the following steps: Step 1: At each drawing head and / or each drawing pass of the multi-head wire drawing equipment, collect the wire drawing tension data of the corresponding copper wire in real time.

When the tension deviates, the system can generate and execute adjustment commands in a timely manner, automatically adjusting the motor speed or linear speed to form a stable closed-loop control mechanism. This effectively avoids problems such as wire breakage and wire diameter fluctuation caused by tension imbalance, and improves the stability, product consistency and production efficiency of the copper wire drawing process.

[0034] This application discloses an intelligent tension adjustment system for multi-head copper wire drawing, referring to... Figure 2 As shown, this system is applied in online continuous wire drawing process to achieve intelligent coordination and stable control of copper wire tension under conditions of multiple drawing heads and multiple passes; The intelligent tension adjustment system for multi-head copper wire drawing includes a multi-point tension acquisition module, an operating parameter acquisition module, a data processing and analysis module, an intelligent decision control module, an execution control module, and a feedback control module. The multi-point tension acquisition module is set at each drawing head of the multi-head wire drawing equipment, and preferably includes multiple tension sensors to collect the copper wire drawing tension corresponding to each drawing head in real time, so as to obtain the tension distribution state of the multi-head wire drawing equipment; the operation parameter acquisition module is used to synchronously collect the operation parameters related to the wire drawing process, including but not limited to line speed, motor speed and wire diameter change parameters, to provide basic operation data support for tension adjustment. The data processing and analysis module is connected to the multi-point tension acquisition module and the operation parameter acquisition module, respectively. It is used to fuse the acquired tension data and operation parameters, and construct a multi-head drawing tension distribution model based on the operation relationship between multiple drawing heads and adjacent drawing passes. This tension distribution model is used to characterize the tension matching state and change trend between each drawing head. The intelligent decision control module is connected to the data processing and analysis module. Based on the obtained tension distribution model, it judges the current wire drawing state according to the preset wire drawing process parameters and historical operating data, and sets the target tension range in combination with the copper wire specification parameters. When the actual tension deviates from the target tension range, it automatically calculates and generates the corresponding tension adjustment command, thereby realizing intelligent decision-making of tension adjustment strategy. The execution control module is connected to the intelligent decision control module and is used to adjust the drive device corresponding to each drawing head according to the tension adjustment command. The execution control module preferably includes a frequency converter, a servo driver, and an electromagnetic braking device to achieve precise control of the drive motor speed, wire feeding speed and wire taking speed. The feedback control module is connected to the execution control module and the intelligent decision control module. It is used to feed back the adjusted tension state to the intelligent decision control module in real time, thereby forming a closed-loop control structure of tension detection-analysis-adjustment-feedback, realizing continuous and stable adjustment of multi-head drawing tension. When abnormal tension or over-limit state is detected, the system can also trigger an alarm mechanism and record abnormal operation data. The system also includes a human-machine interface module, which displays the tension status, operating parameters, and alarm information of each drawing head in real time, facilitating monitoring and management by operators. The adjusted copper wire can then directly enter subsequent processing steps, thereby improving the stability of the continuous drawing process, the consistency of finished products, and overall production efficiency.

[0035] Example 1 This embodiment discloses an intelligent tension adjustment system for multi-head copper wire drawing, applied in multi-head wire drawing equipment, for real-time monitoring and closed-loop stable control of the tension of each drawing head. In this embodiment, the system includes a multi-point tension acquisition module, an operating parameter acquisition module, a data processing and analysis module, an intelligent decision control module, an execution control module, and a feedback control module. The multi-point tension acquisition module includes tension sensors installed at each drawing head to collect the drawing tension data of the corresponding copper wire in real time; the operating parameter acquisition module is used to synchronously collect the linear speed, motor speed and wire diameter change parameters corresponding to each drawing head. The data processing and analysis module integrates the collected tension data and operating parameters to construct a multi-head drawing tension distribution model, which is used to characterize the tension matching relationship between each drawing head and between adjacent drawing passes. The intelligent decision control module calculates the target tension range for each drawing head based on preset wire drawing process parameters and copper wire specification parameters; when the actual tension deviates from the target tension range, it generates a corresponding tension adjustment command. The execution control module adjusts the speed of the drive motor, the unwinding speed, or the winding speed of the corresponding drawing head according to the tension adjustment command; the feedback control module is used to feed back the adjusted tension state to the intelligent decision control module, thereby forming a closed-loop control and realizing stable adjustment of the tension of multi-head drawing. By adopting the technical solution described in this embodiment, problems such as wire breakage and surface defects caused by tension mismatch during multi-head wire drawing are effectively reduced, thereby improving the stability of the wire drawing process and the consistency of finished product quality.

[0036] Example 2 Based on Example 1, this example further discloses an intelligent tension adjustment system for multi-head copper wire drawing suitable for online continuous wire drawing processes. In this embodiment, the intelligent decision control module not only calculates the tension adjustment strategy based on the preset wire drawing process parameters, but also analyzes the tension change pattern under different copper wire specifications, wire drawing passes and operating conditions by combining historical operating data, so as to dynamically optimize the target tension range and adjustment strategy. When the system detects that the actual tension of each drawing head deviates from the target tension range or fluctuates abnormally, the intelligent decision control module generates an adaptive tension adjustment command. The execution control module then coordinates the frequency converter, servo driver, or electromagnetic braking device to achieve rapid and precise adjustment of the tension of multiple drawing heads. Meanwhile, the system also includes a human-machine interaction module, which is used to display the tension status, operating parameters and alarm information of each drawing head in real time; when abnormal tension or over-limit state is detected, the system issues an alarm signal and records abnormal operating data for subsequent analysis and process optimization. In this embodiment, the system is applied to an online continuous wire drawing production line. After adjustment, the copper wire can directly enter subsequent processing steps such as annealing, winding, or finishing without stopping the machine or manual intervention, thereby improving production continuity, reducing downtime, and further enhancing overall production efficiency and automation level.

[0037] The implementation principle of the intelligent tension adjustment method and system for multi-head copper wire drawing in this application embodiment is as follows: During the multi-head copper wire drawing process, the tension states of each drawing head and adjacent drawing passes are coupled with each other. Tension fluctuations of any drawing head may cause tension imbalance and affect the overall drawing stability. This application achieves intelligent and stable control of multi-head wire drawing tension through real-time sensing, comprehensive analysis, and dynamic feedback adjustment of the tension state of multiple drawing heads. Specifically, in practice, copper wire drawing tension data is collected in real-time at each drawing head and / or each drawing pass of the multi-head wire drawing equipment, and operating parameters such as line speed, motor speed, and wire diameter changes are simultaneously acquired. By fusing and analyzing the above multi-source data, a multi-head wire drawing tension distribution model is constructed to characterize the tension matching relationship between each drawing head and between adjacent drawing passes. Based on copper wire specifications and preset drawing process parameters, the target tension range corresponding to each drawing head is dynamically calculated, and the actual tension state is continuously compared with the target tension range. When the actual tension deviates from the target tension range, a corresponding tension adjustment command is automatically generated to intervene and adjust the wire drawing process. Through dynamic adjustment of the drive motor speed, unwinding speed, or take-up speed, the tension state gradually returns to the target range, and the adjustment result is fed back to the control system to form a closed-loop control. This achieves adaptive, continuous, and stable adjustment of multi-head wire drawing tension, improving the stability of the wire drawing process and the consistency of copper wire finished product quality. The intelligent tension adjustment system for multi-head copper wire drawing constructs a closed-loop control system consisting of multi-point tension acquisition, data fusion analysis, intelligent decision control, execution adjustment, and feedback control. This system achieves intelligent coordination and stable control of the tension state of each drawing head in the multi-head wire drawing equipment. During system operation, the multi-point tension acquisition module acquires real-time tension data from tension sensors located at each drawing head. The operating parameter acquisition module simultaneously acquires operating parameters such as linear speed, motor speed, and wire diameter changes, and transmits the acquired data to the data processing and analysis module. The data processing and analysis module then fuses and calculates the tension data and operating parameters. A multi-head drawing tension distribution model is constructed to provide a data foundation for subsequent adjustment decisions. The intelligent decision control module judges the tension state of each drawing head based on the target tension range and the tension distribution model, and generates corresponding tension adjustment commands when the tension is abnormal or deviates. The execution control module adjusts the drive device of the corresponding drawing head according to the tension adjustment commands through a frequency converter, servo driver, or electromagnetic braking device. The feedback control module sends the adjusted tension state back to the intelligent decision control module, forming a stable and reliable closed-loop control mechanism to achieve continuous and stable adjustment of multi-head drawing tension, which is suitable for online continuous drawing production processes.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
