Description

Technical Field

[0001] The present invention relates to the technical field of alloy steel wire production, and in particular to a winding control system and method for an alloy steel wire production line. Background Art

[0002] The alloy steel wire production line is an industrial production line that uses alloy steel wire rod as raw material and produces steel wire through a drawing process. Its main products include galvanized steel wire and electroplated brass steel wire. The winding control of the alloy steel wire production line mainly involves tension control and coil diameter management. For example, closed-loop vector control technology is used to dynamically adjust the motor output torque by providing real-time feedback on coil diameter changes through an encoder, or the coil diameter is calculated in real time through an encoder. Recursive operations and hollow coil diameter activation technology are used to ensure the accuracy of coil diameter calculation.

[0003] The existing winding control methods for alloy steel wire production lines are generally aimed at reducing the friction between the steel wire and the rubber wheel during the winding process, thereby improving the accuracy of tension control during the winding control process. For example, by adding positioning components and winding components, winding reels of different sizes are positioned and the steel wire is wound. Although this improved method can improve the stability of tension control, it cannot effectively control the winding speed during the winding process based on the length of the wound steel wire. As a result, although the tension during winding can be accurately controlled, it can only ensure smooth entry and exit of the steel wire, and the problem of coil shape defects after winding will still occur, affecting the actual steel wire output. For example, in the patent application with publication number CN119797057A, a method for alloy steel wire processing is disclosed. The winding device reduces the friction between the guide and the rubber wheel to zero during the winding process, thereby improving the accuracy of tension control. At the same time, it controls the wire feeding and wire exiting angles between the steel wire and the rubber wheel during the guiding process to ensure smooth wire feeding and wire exiting and maintain the stability of tension control. Other improvements in the winding control of alloy steel wire production lines are usually improvements in the optimization of the winding unit. They are still unable to effectively control the winding speed during the winding process based on the length of the winding steel wire. As a result, although the tension during winding can be accurately controlled, it can only ensure smooth wire feeding and exiting, and will still cause roll shape defects after winding. In view of this, it is necessary to improve the winding control method of the existing alloy steel wire production line. Summary of the Invention

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1, please refer to Figure 1 As shown, the present application provides a winding control method for an alloy steel wire production line, comprising the following steps: Step S1: performing a winding test on the alloy steel wire production line, and obtaining a plurality of tension test points and a winding length of each tension test point based on the test results; performing a speed-tension correlation test on each tension test point, and obtaining a speed-tension test curve for each tension test point based on the results of the speed-tension correlation test; Step S101, the winding test includes: Step S1011, obtaining multiple default gears corresponding to the output speed of the driving motor to the winding drum in the alloy steel wire production line, and recording them as preset gears YD1 to preset gears YD c ; The length of the steel wire that can be wound into the reel is recorded as L; In the specific implementation process, the preset gears can be customized according to the actual speed allowed by the winding reel to ensure that the preset gears are all gears that the winding reel can execute in actual applications, so that the overall analysis of this embodiment is more in line with the actual situation; Step S1012: for any preset gear YD v When there is no steel wire in the reel, the preset gear YD v The steel wire is wound into the reel and the thickness of the steel wire in the reel is obtained in real time until the steel wire of length L is wound into the reel. The data corresponding to the time of winding the steel wire and the thickness of the steel wire are recorded as the steel wire winding data, where v is a positive integer less than or equal to c and greater than or equal to 1; In the specific implementation process, the thickness of the steel wire in this embodiment is the width of the steel wire wound into the winding drum in the cross-sectional direction of the winding drum. Figure 3 As shown, ZZ1 is the cross section of the reel, ZZ2 is the cross section of the reel after the steel wire is wound in, and the thickness of the steel wire is the length of d1; Step S1013: Establish a plane rectangular coordinate system, which is recorded as the involvement analysis coordinate system, wherein the unit of the X-axis of the involvement analysis coordinate system is min, and the unit of the Y-axis is m; draw a corresponding curve in the involvement analysis coordinate system with the time of wire involvement in the wire involvement data as the horizontal coordinate and the thickness of the wire as the vertical coordinate, and record it as the gear involvement curve; except for the leftmost and rightmost points in the gear involvement curve, the point with the smallest slope is recorded as the tension influence point, and the point with the largest slope is recorded as the preferred speed point; the vertical coordinate of the tension influence point is marked as Y1, and the vertical coordinate of the preferred speed point is marked as Y2; In the specific implementation process, due to the consideration of the actual influence of friction and tension, even in the preset gear, there will still be an unstable state of the wound-in wire speed; in the winding-in analysis coordinate system, the point with the largest slope is the point with the fastest wire winding speed, which means that in this preset gear, when the wound-in wire length is at the vertical coordinate of the preferred speed point, the wound-in wire speed is the fastest, and the vertical coordinate of the preferred speed point can be used as the preferred winding length of this gear, providing data support for the construction of the long-speed correlation curve; the point with the smallest slope is the point with the slowest wire winding speed, which means that in this preset gear, the wound-in wire length is affected by friction or tension, resulting in a slow winding speed, and can therefore be used as the target of subsequent analysis to ensure that the winding of wires of different lengths can be performed at the most appropriate speed, to prevent the wound-in wire from being greatly affected by tension, resulting in unstable force on the wire and the existence of winding defects; Step S1014: Obtain a reel without steel wire, wind a steel wire of thickness Y1 into the reel, and record the position of any steel wire in the reel that is farthest from the center of the reel after winding as a tension test point. The length of the steel wire in the reel at this time is recorded as the reeled length at the tension test point. Step S1015: Get a reel without steel wire, wind a steel wire with a thickness of Y2 into the reel, and record the length of the steel wire in the reel as the preset gear position YD. v The preferred winding length; Step S1016, obtaining the tension test points of all preset gears, the winding length of the tension test points, and the preferred winding length.

[0019] Step S102, the speed-tension correlation test includes: Step S1021, for any tension test point: obtain a take-up reel without steel wire, and respectively adjust the reel from the preset gear position YD1 to the preset gear position YD c The steel wire is wound into a reel where no steel wire is present, until the length of the wound steel wire reaches L; Step S1022: For any one time of using the preset gear position YD vWhen the steel wire in the reel reaches the tension test point, a tension sensor is placed at the tension test point and the detection data of the tension sensor is obtained in real time. When the steel wire in the reel stops being wound, the difference between the maximum and minimum tension values ​​in the detection data of the tension sensor is recorded as the winding tension difference. In the specific implementation process, by obtaining the winding tension difference, the tension change at the tension test point when the wire is wound in at the preset gear can be obtained. The larger the winding tension difference, the greater the change in the wire tension at the tension test point when the wire is wound in at this preset gear, and the more likely the problem of wire damage or winding defects will occur; Step S1023, obtaining the winding tension difference corresponding to the tension test point when winding the steel wire into the winding reel without steel wire at all preset gears; establishing a plane rectangular coordinate system, recorded as the speed tension analysis coordinate system, wherein the unit of the X-axis of the speed tension analysis coordinate system is r / min, and the unit of the Y-axis is N; based on the rotation speed corresponding to each preset gear and the winding pressure difference corresponding to the tension test point at each preset gear, mark points in the speed tension analysis coordinate system, and record the curve obtained by fitting all the mark points as the speed tension test curve; Step S1024, obtaining the speed tension test curves corresponding to all tension test points.

[0020] Step S2, performing a winding simulation in the alloy steel wire production line based on the winding length of each tension test point and the speed tension test curve, and obtaining a length-speed correlation curve based on the results of the winding simulation; Step S2 includes: Step S201: performing a winding simulation in the alloy steel wire production line based on the winding length and speed-tension test curve of each tension test point. The winding simulation includes: for any tension test point, marking the point with the lowest vertical coordinate in the speed-tension test curve corresponding to the tension test point as the tension fluctuation valley point, and marking the horizontal coordinate of the tension fluctuation valley point as the stable winding speed; In the specific implementation process, through the above analysis, it can be obtained that in the speed test curve, the smaller the vertical coordinate of a point is, the smaller the speed corresponding to the horizontal coordinate of the point is applied to the actual steel wire reeling, and the smaller the change amplitude of the steel wire tension at the tension test point is, the more it can ensure that the steel wire at the tension test point can be in a stable stress state when the entire steel wire is reeled in. Therefore, the point with the lowest vertical coordinate should be marked, that is, the tension fluctuation valley point is obtained; for example, in a data analysis, the speed test curve obtained is as follows Figure 4 As shown in the figure, through analysis, it can be obtained that the tension fluctuation valley point is ZG, and the stable winding speed is XX1. This means that for the tension test point, when the speed of winding the steel wire is XX1, the steel wire at the tension test point is subjected to the most stable force during the entire steel wire winding process. Step S202: Obtain a reel without steel wire, wind a steel wire of length L1 into the reel at a stable reeling speed, randomly obtain a tension test point in the reel, and place a tension sensor. The detection result of the tension sensor at this time is recorded as N1, where L1 is the reeling length corresponding to the tension test point. Continue to reel the steel wire into the reel and obtain the detection result of the tension sensor in real time until the length of the steel wire in the reel reaches L, at which time the reeling stops. Step S203: After the wire is wound in, the time corresponding to the detection result of the tension sensor with the smallest difference from N1 is recorded as the tension selectable time, and the length of the wire in the winding drum during the tension selectable time during the wire winding process is recorded as the tension preferred length for a stable winding speed, wherein there can be multiple tension selectable times; In a specific implementation process, the minimum value of the difference between the detection data of the tension sensor and N1 can be 0. By obtaining the tension optional time, the winding length of the steel wire that can maintain a stable force at the tension test point while maintaining a stable winding speed can be obtained, so as to facilitate the subsequent acquisition of the long-speed correlation curve, that is, to ensure that the wound steel wire is under a relatively stable tension state. The relationship curve between the length of the wound steel wire and the winding speed is conducive to effectively controlling the winding speed during the actual winding process based on the length of the wound steel wire; Step S204: Analyze all tension test points and obtain the optimal tension length for a stable winding speed corresponding to each tension analysis point based on the analysis results; Step S205: Establish a plane rectangular coordinate system, recorded as the long-speed analysis coordinate system, wherein the unit of the X-axis of the long-speed analysis coordinate system is m, and the unit of the Y-axis is r / min; for the stable winding speed corresponding to any tension analysis point, use the stable winding speed as the vertical coordinate and the preferred tension length at the stable winding speed as the horizontal coordinate to mark the long-speed analysis coordinate system, and use each preset gear and the preferred winding length of the preset gear as the vertical coordinate and the horizontal coordinate to mark the long-speed analysis coordinate system; Step S206: Record the curve obtained by fitting all the punctuation points as a long-speed correlation curve.

[0021] Step S3, when winding the alloy steel wire in the production line, adjusting the speed of the winding reel output by the driving motor in real time based on the long-speed correlation curve; Step S3 includes: step S301, when the steel wire is wound into the winding drum, obtaining the length of the steel wire in the winding drum in real time and recording it as L2; ​​marking the vertical coordinate corresponding to the point with the horizontal coordinate L2 in the long-speed correlation curve as the adjusted speed; In the specific implementation process, the speed can be adjusted in real time according to the change of the actual length of the steel wire in the winding drum, so as to ensure that the steel wire in the winding drum is in a stable stress state when the steel wire is wound; Step S302: Control the driving motor to adjust the output speed of the winding reel to the adjusted speed.
