"The magic weapon for the strength and prosperity of German industry also stems from the solid basic research of research universities and their close integration with enterprises in product application research; from the product and industrialization incubation role played by the enterprises in which the scientific research institutes are located in the process of new product development with their strong engineering technology ability; and from the practical cooperation of value recognition, complementary advantages and efficient coordination among the relevant parties in the industrial chain." recently, Lu Chao, the rotating executive chairman of the gear transmission industry branch of the China Europe Association and the chairman of Tianjin Tianhai synchronous Group Co., Ltd., said at the "2017 China gear industry market demand technical support and industrial and financial cooperation seminar" held in Hanzhong, Shaanxi Province. The participants focused on the theme of "strengthening the foundation and collaborative innovation", and discussed how to develop the traditional gear industry? There was a heated discussion on how to transform the basic industry on which the automobile transmission depends.
Weak industrial infrastructure severely restricts the innovation and development of manufacturing industry
Lu Chao believes that the reason why German industry is strong and prosperous is that it always adheres to the manufacturing industry as the foundation of the country, always adheres to the industrial structure with the manufacturing industry as the main body, and always adheres to the priority of finance to serve the manufacturing industry and its innovation activities. Through exchanges with the German side, we are more aware that additive manufacturing technology can solve large and complex parts.
This is the feeling of Lu Chao who has visited German enterprises for many times and conducted in-depth exchanges in the past two years. He said: "made in China 2025 takes strengthening industrial basic capabilities, that is, strengthening the" four basic "capabilities of core basic parts (components), advanced basic processes, key basic materials and industrial technology, as China's strategic task to achieve a manufacturing power; The weak industrial infrastructure has seriously restricted the innovation and development of China's manufacturing industry and the improvement of product quality. "
The development of high technology and strategic industries needs long-term accumulation
Liupeiwen, Deputy Secretary General of the China Association for European Economic and technological cooperation, said at the meeting: "domestic enterprises should take more strategies to open up a second growth curve to boost the development of high-tech and strategic industries. The development of high-tech industries and strategic industries often requires a long time of experience accumulation. The whole industry and related enterprises need to be patient, inheritance and persistence to maintain the focus on development and patient development."
Liupeiwen said that the development of high-tech and strategic emerging industries shows the following characteristics: first, there are many bright spots in technological innovation, and the improvement of quality and efficiency has been steadily promoted, but the overall innovation ability still needs to be further improved; Second, the differentiation in the industry and field is increasingly prominent, and the differentiation will exist for a long time; Third, there are new ways to support the development of financial industry, but the problems of difficult and expensive financing remain; Fourth, the corresponding international mergers and acquisitions have improved the image of domestic enterprises, and foreign investment has enhanced the development ability of domestic enterprises.
More and more scientific research institutes and enterprises attach importance to basic research and development
Under the leadership of academician wanghuaming, the National Engineering Laboratory for additive manufacturing of large metal components of Beijing University of Aeronautics and Astronautics has won the first prize of the "National Technological Invention Award" and other awards in the application of additive manufacturing (3D printing) technology and high-performance additive manufacturing technology for large metal components. Dr. tanghaibo, who delivered the speech on behalf of Academician Wang, said that from the perspective of the gear and bearing industry, through the 3D printing technology of additive manufacturing, the gear material performance can have high bending fatigue strength and contact fatigue strength, the tooth surface has sufficient hardness and wear resistance, and the core of the part has good strength and toughness. In terms of gear manufacturing technology, the 3D printing of additive can achieve high precision, high quality, high efficiency and green environmental protection. At the same time, the metallurgical defects and properties of the bad materials of large gear castings/forgings can be restricted accordingly, making the tooth surface more bearing capacity and higher reliability. From the perspective of development trend, additive manufacturing solves the problems of large-scale, high-quality and high-performance in traditional metallurgy, which can make multi-material/gradient high-performance, alternate manufacturing and remanufacturing, and integrate structure and function.
