Industry 4.0 is the representative of intelligent manufacturing, and its concept and technology are driving the intelligent upgrade of aluminum alloy forging production lines. The following are the development trends in several key aspects: 1. Automation: Aluminum alloy forging production is a fully automated process that can be completed without human intervention. Through the use of automated robots and sensors, faster, more accurate and less costly production processes can be achieved. 2. Data analysis: In the production of aluminum alloy forgings, data is very important. Collecting, storing, and analyzing data can help companies obtain real-time performance and reliability information on production lines to make better decisions and plans. 3. Internet and Internet of Things technology: To undertake 2 points, the Internet and Internet of Things technology provide convenient cross-platform communication methods and equipment management methods for the production of aluminum alloy forgings, including the ubiquity of Internet of Things devices and big data processing technology. 4. Integration of digital technology: With the promotion of Industry 4.0 for aluminum alloy forging production lines, digital technology is more and more widely used, such as 3D printing, virtual reality and artificial intelligence will help design optimization, development of new products and optimization of processes. In summary, although there are still challenges in the intelligent upgrading of aluminum alloy forging production line, with the gradual maturity of industry 4.0 technology, it will promote the aluminum alloy forging production line to become more intelligent, automated and efficient. This will help companies improve quality, reduce costs and achieve sustainable and efficient production.
