With the continuous development of science and technology, the traditional manufacturing field is also constantly introducing intelligent technology. As one of the important production processes, die casting machines are widely used in industrial production, and the requirements for product quality are getting higher and higher. Therefore, the use of intelligent quality analysis and defect prediction technology can help the die casting machine industry to better improve product quality and reduce the generation of substandard products. This article will discuss the application of intelligent quality analysis and defect prediction in the die casting machine industry, including its principles, methods and techniques.
A die-casting machine is a common metal processing equipment that injects molten metal into a mold through high pressure, and then cools and solidifies to form a shape. However, in the die-casting process, there are often some defects, such as thermal cracks, pores, slag inclusions, etc. These defects will directly affect the quality and performance of the product. Therefore, predicting and analyzing these defects in advance is very important for improving the manufacturing process and product quality.
2. Principles of Intelligent Quality Analysis and Defect Prediction
Intelligent quality analysis and defect prediction technology is based on the application of artificial intelligence and data mining technology. Through the analysis and modeling of a large number of production data, it can predict the quality defects that may occur in the die-casting process. Its principle can be divided into the following aspects:
Data acquisition and cleaning: Collect relevant data of the die-casting machine through sensors and instruments, including temperature, pressure, flow and other information, and clean and preprocess the data to ensure the accuracy and integrity of the data.
Feature extraction and selection: Extract meaningful features from the collected data, such as vibration frequency, pressure change, temperature gradient, etc. These features can be used to describe the die casting process and potential defects.
Model building and training: Use machine learning algorithms or deep learning models to train based on the extracted features and defect data to build a defect prediction model. Commonly used algorithms include support vector machines, decision trees, neural networks, etc.
Model evaluation and optimization: Evaluate the trained model through model evaluation indicators (such as accuracy rate, recall rate, etc.) to further optimize the performance and predictive ability of the model.
3. Intelligent quality analysis and defect prediction method
In the die casting machine industry, intelligent quality analysis and defect prediction can adopt a variety of methods and technologies. Common methods include the following:
Rule-based method: manually formulate a series of rules and specifications, match and judge according to real-time collected data, so as to judge whether the product has defects. However, this method often has high requirements for the formulation and update of rules, and it is difficult to deal with complex defect situations.
Method based on statistical analysis: through statistical analysis of historical data, the establishment of probability models and mathematical models to predict the quality and possible defects of the current production status. This method can better adapt to the production changes and diverse defect types in the die casting machine industry.
Machine Learning-Based Approach: Use machine learning algorithms to learn patterns and regularities from a large amount of production data and predict the quality and defects of the current production status. Common algorithms include support vector machines, random forests, neural networks, etc. This approach not only predicts defects, but also uncovers new associations and regularities hidden in the data.
Methods based on deep learning: Deep learning is an important branch of machine learning, which can perform feature extraction and pattern recognition through multi-layer neural networks. In the die casting machine industry, deep learning methods can be used to analyze and predict complex production data to improve the accuracy of defect detection and diagnosis.
