As the key parts of the engine, the production technology of the main and auxiliary connecting rod forging is very important to the quality and performance of the product. There are some differences and gaps in the production technology of main and auxiliary link forging at home and abroad, this paper will compare and analyze the technology at home and abroad.
Technical comparison at home and abroad
Production process: The domestic production process of main and auxiliary connecting rod forging is relatively mature, but it is still dominated by traditional processes, such as free forging, die forging, etc. Foreign countries have a high level of technology in precision forming, heat treatment and surface treatment, and can produce higher quality products.
Equipment and equipment: The production equipment and equipment of the main and auxiliary connecting rod forging in China is relatively old, and the degree of automation is low. In foreign countries, advanced CNC machine tools, industrial robots and other intelligent equipment are generally used to improve production efficiency and product quality.
Material research and development: Domestic research and development of main and auxiliary connecting rod forging materials is still in its infancy, while foreign countries have developed a variety of new high-strength, lightweight materials, improving the performance and competitiveness of products.
Quality control: China has made some progress in the quality control of main and auxiliary connecting rod forgings, but there is still a certain gap compared with foreign countries. Foreign enterprises generally adopt advanced testing equipment and testing methods to ensure product quality.
Environmental protection and sustainable development: foreign countries pay more attention to environmental protection and sustainable development in the production process of main and auxiliary connecting rod forging, the use of green production technology and environmentally friendly materials to reduce energy consumption and emissions. However, domestic efforts in this area still need to be strengthened.
The causes of technological gap
Insufficient research and development investment: Domestic enterprises have relatively little investment in research and development of main and auxiliary connecting rod forgings, and lack of power and financial support for core technology research and development. Foreign enterprises focus on continuous research and development investment to maintain a leading position in technology.
Shortage of technical personnel: there is a relative shortage of technical personnel in the field of domestic main and auxiliary connecting rod forging, and there is a lack of artisans with advanced skills and experience. While foreign countries pay attention to personnel training and technical inheritance.
Imperfect industrial chain supporting: The domestic main and auxiliary connecting rod forging industry chain supporting is not perfect, lack of high-end materials, precision equipment and other key links of support. Foreign countries have formed a complete industrial chain, which is conducive to the continuous innovation and progress of technology.
Innovation environment difference: There are some differences between domestic innovation environment and foreign countries, which pay more attention to the protection of intellectual property rights and the cultivation of innovation culture, which is conducive to the incubation and transformation of technology. At home, we need to further strengthen the construction of innovation environment.
Coping strategy of technology gap
Increase research and development investment: Domestic enterprises should increase research and development investment in the field of main and auxiliary connecting rod forgings, improve independent innovation ability, and break through key technical bottlenecks. At the same time, the government should also give corresponding policy support and financial guidance.
Training of technical personnel: strengthen the training of technical personnel and establish a sound system of technical personnel. Through industry-university-research cooperation, skill training and other means, improve the technical personnel’s skill level and innovation ability.
Improve the industrial chain supporting: strengthen the cooperation and collaborative development of upstream and downstream enterprises in the industrial chain, improve the supporting system of key links such as high-end materials and precision equipment, and enhance the competitiveness of the entire industrial chain.
Optimize the innovation environment: The government should strengthen the protection of intellectual property rights and the cultivation of innovation culture to create a good atmosphere for innovation. At the same time, an innovation service platform will be established to promote cooperation and exchanges between enterprises and scientific research institutions.
Introduction and absorption of international advanced technology: Through the introduction of international advanced technology, accelerate the progress and development of domestic technology. At the same time of the introduction of technology, we should pay attention to the digestion, absorption and re-innovation of technology to form a core technology with independent intellectual property rights.
In summary, there is a certain gap in the production technology of main and auxiliary link forging at home and abroad, but through the implementation of measures such as increasing research and development investment, training technical personnel, improving the industrial chain supporting and optimizing the innovation environment, the gap with the international advanced level is gradually narrowed, and the overall competitiveness of China’s main and auxiliary link forging is improved.
