Analysis on the development trend of precision forging

1. Continuous process innovation. In order to meet the requirements of formed parts and reduce production costs, precision casting needs to continuously develop new precision forging processes with high forming accuracy, long mold life and high production efficiency.

2. Development of composite processes. With the continuous improvement of the process requirements for formed parts, it is difficult for a single precision forging to meet the requirements. This requires the development of composite forming processes, combining forging processes with different temperatures or different process methods, and completing the processing and manufacturing of a part by taking advantage of each other's strengths and weaknesses. Precision forging processes can also be combined with other precision forming processes such as precision casting and precision welding to improve the application range and processing capabilities of precision forming processes.

3. Knowledge-based process design. With the continuous development of precision forging technology, process design is becoming more and more complex. In order to improve the reliability and efficiency of process design, the development of knowledge-based expert systems is an important research direction for future precision forging process design.

From production to invention, creating the value of the entire industrial chain is the theme of this forum. Of course, the competition among modern companies is no longer just a competition of the strength of a single company, but more reflected in the competition of management quality, cost advantage and rapid response of upstream and downstream companies in the entire industrial chain. The success of the entire industrial chain is the foundation for the rapid development of Chinese companies and the code for the transformation and upgrading of China's manufacturing industry. The forging process includes: cutting the material into the required size, heating, forging, heat treatment, cleaning and inspection. In small-scale manual forging, all these operations are carried out by several forgers in a small space. They are all exposed to the same harmful environment and occupational hazards; in large-scale forging workshops, the hazards vary with different jobs. Working conditions Although working conditions vary according to different forging forms, they have certain common characteristics: moderate intensity physical labor, dry and hot microclimate environment, noise and vibration, and air polluted by smoke. Workers are exposed to high temperature air and thermal radiation at the same time, which causes heat accumulation in the body. Heat plus metabolic heat can cause heat dissipation disorders and pathological changes. The amount of sweat produced in 8 hours of work will vary depending on the micro-gas environment, physical exertion and degree of heat adaptability, generally between 1.5 and 5 liters, or even higher. In smaller foundries or farther away from heat sources, the Behavioral Heat Stress Index is usually 55 to 95; but in large foundries, the working point near the heating furnace or the drop hammer may be as high as 150 to 190. It is easy to cause salt deficiency and heat cramps.

Talking about quality and brand issues, Li Yizhong believes that high quality and famous brands should become the symbol of Chinese manufacturing. "Brand is the intersection of material culture, and it is also a symbol of economic development and social progress. Chinese products are inexpensive and popular all over the world, but there are also many problems. The quality-oriented national strategy has not become a fundamental national policy, and there are some shortcomings in the system mechanism. The responsibility of the company is to provide high-quality products and services to the society.
