However, the forming process of aluminum alloy is complex and sensitive to process parameters. Different forming conditions will directly affect the performance and quality of the product. Therefore, it is very important to accurately control the aluminum alloy forming process and perform performance testing.

[0003] The traditional aluminum alloy forming process mainly relies on manual experience and simple monitoring equipment, which has many shortcomings. Manual monitoring makes it difficult to achieve real-time monitoring and precise control of all parameters in the forming process, resulting in unstable product quality and serious material waste. Traditional detection methods mostly rely on manual visual inspection, which is not only inefficient but also easily affected by human factors, resulting in missed defects or misjudgment. In addition, with the continuous development of aluminum alloy forming technology, the complexity of product structure and the requirements for precision are getting higher and higher. Traditional detection methods can no longer meet the needs of modern production. For this reason, we propose a performance detection system for aluminum alloy forming. Summary of the invention

[0041] Storage module, which stores collected data, analysis results, equipment parameters, and operation record information, and backs up and encrypts data;

[0042] Various sensors include temperature, humidity, pressure and displacement sensors. The preprocessing method is to clean and normalize the data. The data acquisition module also includes a sensor scheduling unit, which is used to adjust the position of the sensor in the environment;

[0043] The processing and analysis module includes a data visualization unit, an image preprocessing unit, a feature extraction unit and a defect recognition unit.

The specific method of feature classification is to establish a convolutional neural network model and use a labeled defect image data set for training. The specific method of feature recognition is to use the trained model to detect the image data segmented by the image preprocessing unit and determine the defects in the image.

[0044] Specific work flow: In an automobile parts manufacturing enterprise, the aluminum alloy forming performance detection system of the present invention was introduced;

[0045] The data acquisition module collects data in the production environment in real time through temperature, pressure, displacement and other sensors and monitoring probes. For example, during the die-casting process, the temperature sensor monitors that the mold temperature is around 650°C, and the pressure sensor shows that the die-casting pressure is 120MPa. The sensor scheduling unit adjusts the sensor position according to the production progress to obtain more accurate data.

[0046] The processing and analysis module processes the collected data. The data visualization unit converts the sensor data into numerical format and cleans and aggregates it. A data report is generated every 24 hours. The image preprocessing unit segments the images collected by the monitoring probe. The feature extraction unit analyzes the texture and shape characteristics of the surface of the aluminum alloy parts and determines that it is an aluminum alloy part of the automobile engine cylinder. The convolutional neural network model is used for defect recognition. The trained model detects that the probability of tiny pore defects on the surface is 0.5%.

[0047] The control module generates equipment parameter adjustment instructions based on the analysis results. For example, when it is found that the die-casting pressure is slightly low, the instruction generation unit generates an instruction to increase the pressure, which is transmitted to the actuator control unit through the instruction transmission unit to increase the die-casting pressure to 130MPa. The safety protection unit monitors the equipment status in real time during the entire adjustment process to ensure safety.

[0048] In the molding module, the molding simulation unit uses MAGMAsoft die-casting molding simulation software. The parameter input unit receives aluminum alloy material parameters (such as aluminum alloy grade, composition, etc.), mold parameters (mold size, cooling system, etc.) and molding process parameters (die-casting speed, pouring temperature, etc.). The defect prediction unit predicts that the defect type that may appear under the current parameters is shrinkage cavity, which is mainly located in the thick wall part of the component, and gives an optimization plan, such as adjusting the pouring temperature and die-casting speed. The molding execution unit performs production according to the optimization plan, effectively reducing the occurrence of shrinkage cavity defects.

[0049] The monitoring and feedback module monitors the production process in real time. When the temperature is abnormal, the real-time temperature reaches 680°C, exceeding the preset temperature value of 670°C. The data analysis unit calculates the temperature abnormality value to be 0.08, which is judged as a medium abnormality. A flashing light alarm is issued and related emergency equipment is stopped.

[0050] The performance detection module performs performance detection on the formed parts. The performance detection unit detects that the tensile strength is 350MPa, the fracture toughness is 25MPa·m^(1 / 2), and the corrosion resistance is tested in a simulated corrosion environment with a corrosion rate of 0.05mm / a. The performance judgment unit calculates the performance index C as 0.7 according to the formula, indicating that the performance of this batch of aluminum alloy parts is good.

[0051] The display unit of the display and interaction module displays production data and system operation status in real time, and the voice prompt unit promptly broadcasts when abnormal conditions occur;

[0052] The storage module stores collected data, analysis results, equipment parameters, and operation record information in a classified manner, and regularly backs them up to external storage media. The data is encrypted so that only authorized personnel can access it.

[0053] By using this system, the company's automotive aluminum alloy parts production efficiency increased by 30%, and the defective product rate was reduced from the original 5% to 1%.

[0054] Furthermore, by utilizing image processing and machine learning techniques, the collected data is visualized, image preprocessed, feature extracted, and defect identified, thereby improving the recognition accuracy and efficiency of aluminum alloy surface defects. At the same time, the control module intelligently generates equipment parameter adjustment instructions based on the analysis results, and achieves precise control through the actuator, thereby optimizing the aluminum alloy forming process, reducing material waste and the time cost of subsequent corrections, and thus improving overall production efficiency and product quality.

The defect prediction unit is used to predict the defect type and location that appear in the aluminum alloy forming process and give the corresponding optimization plan. The forming execution unit will generate specific equipment parameter adjustment instructions according to the optimization plan of the forming simulation unit, and transmit them to the actuator of the forming execution unit through the instruction transmission unit;

[0058] The monitoring and feedback module includes a data analysis unit, which can process and analyze the sensor data received in real time, identify the abnormal state and trend of temperature, pressure and displacement during the molding process, determine the type and severity of the abnormal data, and execute the corresponding alarm mechanism according to the severity. The severity is divided into slight abnormality, medium abnormality and severe abnormality, and the severity is determined by the formula. The specific formula is as follows:

The defect recognition unit uses a convolutional neural network model to detect that the probability of surface scratch defects is 0.3%.

[0066] The control module generates equipment parameter adjustment instructions. For example, when it is found that the pressure is unstable during the pressure processing, the instruction generation unit generates an instruction to adjust the pressure, which is transmitted to the actuator control unit through the instruction transmission unit to make the pressure stable within the range of 150 MPa ± 5 MPa. The safety protection unit ensures the safety during the equipment adjustment process.
