Casting is an important foundation in mechanical manufacturing, and its quality directly affects the performance and service life of the final product. Therefore, strict inspection and control of the casting production process is essential. With the continuous development of science and technology, the application of intelligent detection and control technology in casting production is more and more extensive, which greatly improves the quality and production efficiency of castings. In this paper, the intelligent detection and control technology in casting production will be deeply discussed.
Intelligent detection technology
Radiographic inspection
X-ray inspection is a kind of inspection method to detect the internal defects of castings by irradiating them. In intelligent inspection, X-ray inspection can automatically carry out image acquisition and defect identification, which greatly improves the accuracy and efficiency of detection.
Ultrasonic detection
Ultrasonic inspection uses the characteristics of ultrasonic waves propagating in castings to detect their internal defects. Intelligent ultrasonic detection can achieve accurate detection of internal defects in castings by computer simulation and analysis of ultrasonic propagation path and reflection.
Machine vision inspection
Machine vision inspection is a method of automatic inspection using computer vision technology. Through image acquisition, processing and analysis, the surface defects and size errors of castings can be detected, which has the characteristics of high efficiency and accuracy.
Intelligent control technology
Process parameter optimization
Intelligent control technology can optimize the process parameters according to raw materials, molds and other factors to ensure the stability and quality of casting production. For example, through algorithms such as neural networks, key parameters such as melting temperature and pouring speed can be precisely controlled.
On-line quality monitoring
Online quality monitoring is the real-time monitoring and feedback of key parameters in the production process of castings through sensors and other technologies to achieve real-time adjustment and control of the production process. For example, by measuring the temperature and pressure of the cooling water, the cooling rate and shrinkage of the casting can be determined, so as to adjust the process parameters in time.
Automatic control
Automation control is the use of computers, PLC and other equipment, the casting production process for automatic control. Through automatic control, manual errors can be reduced, and production efficiency and product quality can be improved. For example, the use of PLC programming to achieve automatic control of the pouring process to ensure the stability and accuracy of the pouring process.
