Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy processing, and in particular to an aluminum alloy profile production and processing optimization control method and system. Background Art

[0002] The production and processing of aluminum alloy profiles is an important application direction in the field of materials science and engineering technology. This field involves the manufacturing and processing of aluminum alloy materials, and the key links include extrusion, cooling and surface treatment processes. Aluminum alloy profiles are widely used in industries such as construction, transportation and aerospace due to their excellent mechanical properties and corrosion resistance. Especially in the extrusion production process of aluminum alloy profiles, how to effectively control and optimize processing parameters to ensure product quality and performance is a core issue in this field. With the advancement of manufacturing technology, the complexity of production processes has increased, and the demand for real-time data collection and processing and dynamic adjustment of process parameters has also increased.

[0003] Although automated control systems have been widely used in the current production process of aluminum alloy profiles, these systems often face the following problems: First, data collection and processing often lag behind, making it difficult to reflect the actual status of the processing process in real time, resulting in an inability to quickly respond to abnormal situations in production. Second, most of the existing process optimization methods are based on historical data and empirical rules, lacking dynamic analysis and adjustment of real-time data, and often unable to effectively respond to new problems that arise during the processing process. Third, the optimization algorithms in existing systems are relatively simple, and fail to comprehensively consider factors such as grain size, stress relaxation, and oxide layer thickness, resulting in limited optimization effects and an inability to comprehensively improve product quality;

[0004] The above problems are mainly caused by the lack of real-time data processing capabilities of traditional systems and the limitations of process optimization algorithms. In the production process, due to the lack of timely data collection, adjustments can only be made based on preset fixed parameters. This makes it difficult to ensure the stability of the processing process and the high quality of the product when facing the ever-changing conditions in actual production. Insufficient process optimization will lead to problems such as uneven grain size, insufficient stress relaxation, and uneven oxide layer of the product, which not only affects the mechanical properties and appearance quality of the product, but may also increase material waste and production costs. Ultimately, these deficiencies may cause the performance of aluminum alloy profiles to fail to meet application requirements, affecting the market competitiveness of the product.

The processing quality evaluation unit provides an intelligent optimization strategy by comparing and analyzing the processing quality threshold. If the product quality meets expectations, the system does not need iterative optimization; otherwise, the system will automatically generate a second iteration mechanism for further optimization and adjustment. This intelligent quality evaluation and optimization mechanism improves the accuracy of the production process and ensures the competitiveness of the product in the market.

[0115] The optimized product quality Qprod is output through the following product quality algorithm formula;

[0116]

[0117] Where Mop represents the target size;

[0118] The comprehensive processing quality analysis unit performs comprehensive calculation on the obtained optimized product quality Qprod, the actual energy consumption Ea, the optimized product defect rate Dde and the initial product defect rate Din in the standard data group to obtain the comprehensive processing score Score;

[0119] The comprehensive processing score Score is calculated by the following algorithm formula;

[0120]

[0121] Where Tres represents the system response time, which is extracted from the processing equipment work log, Qtarget represents the target product quality, represents the defect rate, a1, a2, a3 and a4 represent the preset weight values ​​of product quality, energy efficiency level, system response time and defect rate respectively, and a1+a2+a3+a4=1.

[0122] The processing quality assessment unit presets the processing quality threshold D based on the target processing quality of the aluminum alloy profile, and then conducts a secondary comparative assessment with the obtained comprehensive processing score Score to analyze the product quality status after the processing equipment is optimized;

[0123] When the comprehensive processing score Score>processing quality threshold D, it means that when the initial processing equipment is initially optimized normally, the production and processing quality of aluminum alloy profiles is abnormal. At this time, the iteration mechanism is executed, the system is re-executed, and the processing equipment is optimized and adjusted again;

[0124] When the comprehensive processing score Score ≤ the processing quality threshold D, it means that when the preliminary processing equipment is initially optimized normally, the production and processing quality of the aluminum alloy profile is also normal, and there is no need to generate an iterative mechanism at this time.

[0125] In this embodiment, the processing quality optimization analysis module of the system comprehensively improves the production quality and efficiency of aluminum alloy profiles through the product quality analysis unit, the comprehensive processing quality analysis unit and the processing quality evaluation unit. The product quality analysis unit uses the product quality algorithm formula to integrate the key parameters such as alloy grain size uniformity GL, aluminum alloy profile impact resistance ML, yield strength Tyi, hardness H, surface quality SL and actual size Dop, and accurately calculates the optimized product quality Qprod. This process not only improves the evaluation accuracy of product quality, but also provides a clear quantitative basis for the optimization target. The comprehensive processing quality analysis unit calculates the comprehensive processing score Score by combining the optimized product quality Qprod with the actual energy consumption Ea, the optimized product defect rate Dde and the initial product defect rate Din. This comprehensive scoring system takes into account the weights of product quality, energy efficiency, response time and defect rate, and provides a quantitative reference standard for comprehensively evaluating the processing quality. The processing quality evaluation unit further performs a secondary evaluation based on the comparison between the comprehensive processing score Score and the preset processing quality threshold D to ensure the practical application of the optimization effect. When the comprehensive processing score Score is lower than the processing quality threshold D, the system will trigger the second iterative optimization to continuously improve product quality.
