2.3 The Study of Stamping Process
In the study of sheet metal stamping process, the research content mainly involves the mechanical manufacturing mechanism, the physical phenomenon and the exchange of information and energy between the mating part surfaces, and the dissipative phenomenon of heat, noise and vibration.
At the same time, the reliability and rationality of the stamping process design has also become a research point. Through the analysis of the springback of stamping parts, finite element analysis (FEA) has been used to predict the accuracy of the formed parts and the parts strain variation law.
3 Application of Intelligent Control Technology
The application of intelligent control technology in the field of sheet metal stamping has helped to improve production efficiency and produce parts with higher precision. Through the optimization of stamping parameters and the optimization of process planning and control, the stamping efficiency of the parts can be improved, and the quality of the parts can be improved after intelligent detection.
At the same time, intelligent control technology has also been applied to the detection of process parameters and the prevention of defects. With the help of the intelligent measuring system, the process parameters can be adjusted in real time according to the shape of the parts, so as to realize the optimal adjustment of stamping parameters and ensure the quality of the parts.
4 Improvements in Parts Quality and Precision
Due to the continuing development of accurate forming technology, the precision and surface quality of the formed parts have been continuously improved. The optimization of die design and the application of FEA technology have enabled higher forming precision and less stamping defects. At the same time, the application of precision machining tools and the improvement of surface treatment technology have improved surface quality, enabling the production of high-precision and high-quality parts.
5 Development of Advanced Materials and New Technologies
With the development of sheet metal stamping technology, advanced materials have been widely used in the production of metal parts, such as aluminum alloys, stainless steel, titanium alloys, etc. At the same time, the application of advanced technologies such as metal micro-forming, metal forming at low temperature, integrated forming and micro-alloyed forming has also been widely applied in the production of metal parts.
