The main and auxiliary connecting rod forging is the key part in the machinery manufacturing, and its production technology level is directly related to the performance and safety of the machinery. In this paper, the production technology of main and auxiliary connecting rod forging at home and abroad is compared, and its development trend is discussed.
Comparison of forging production technology of main and auxiliary connecting rod at home and abroad
Raw material selection: There are some differences in raw material selection at home and abroad. Domestic mainly uses high-quality carbon structural steel and alloy structural steel, while foreign countries are more inclined to use high-strength lightweight materials, such as titanium alloy, aluminum alloy and so on.
Forging equipment: The domestic main and auxiliary connecting rod forging production mainly adopts free forging and die forging equipment. Free forging equipment is suitable for the production of large forgings, while die forging equipment is suitable for the production of small and medium forgings. Foreign countries pay more attention to the automation and intelligence of equipment, and use high-precision equipment such as CNC machining centers for production.
Heat treatment technology: The heat treatment technology of domestic main and auxiliary connecting rod forgings is gradually improving, but there is still a certain gap. Foreign countries have higher technical levels in heat treatment process, temperature control, cooling speed, etc., which can better improve the mechanical properties of materials.
Surface treatment technology: Surface treatment technology is of great significance to improve the wear resistance, corrosion resistance and beauty of the main and auxiliary connecting rod forgings. Domestic surface treatment technology has made some progress, but there is still a certain gap with foreign countries. Foreign technologies in coating, electroplating, spraying and other aspects are more advanced, and better surface quality can be obtained.
Development trend analysis

In the future, more attention will be paid to the application of environmental protection technologies, such as the emission reduction and treatment of waste gas and waste liquid, to reduce energy consumption and resource consumption, and achieve sustainable development.
Intelligent manufacturing: Intelligent manufacturing is an important trend in the future manufacturing industry. Through the introduction of advanced technologies such as artificial intelligence, big data, and the Internet of Things, automation, information and intelligence in the production of main and auxiliary connecting rod forgings are realized, and production efficiency and product quality are improved.
Application of high-strength materials: The application of high-strength materials is an important means to improve the performance of main and auxiliary connecting rod forging. In the future, more attention will be paid to the development and application of high-strength lightweight materials, such as titanium alloy, aluminum alloy, etc., to meet the high performance requirements of machinery.
Personalized customization: With the diversification of market demand, personalized customization will become an important trend in the production of main and auxiliary connecting rod forging. Through the introduction of customized production mode, to meet the individual needs of different customers, improve the added value of products and market competitiveness.
Industrial upgrading and transformation: With the changes in the domestic and foreign market environment and economic situation, the main and auxiliary connecting rod forging industry will face the pressure of upgrading and transformation. Enterprises need to strengthen technological innovation and brand building, improve independent innovation capabilities, and promote industrial transformation and upgrading to adapt to changes in market demand.
In summary, there are some differences in raw material selection, forging equipment, heat treatment technology and surface treatment technology of main and auxiliary connecting rod forging production technology at home and abroad. In the future, with the improvement of environmental awareness, the development of intelligent manufacturing, the research and development and application of high-strength materials and the growth of demand for personalized customization, the production of main and auxiliary connecting rod forgings will show the development trend of green environmental protection, intelligent manufacturing, high-strength material application and personalized customization. Enterprises need to keep up with market demand and technological development, strengthen technological innovation and industrial upgrading to adapt to future development and change.
