The first group of Chinese Academy of Sciences’ Knowledge Innovation Project major project “Integrated Laser Intelligent Manufacturing and Flexible Processing Research†was presided over by the Institute of Mechanics, Chinese Academy of Sciences. "Integrated laser intelligent manufacturing and flexible processing system", and aimed at the problems of short service life and high maintenance cost of stamping dies that restrict the further development of China's automobile industry, using the principle of interaction between laser and materials and combining intelligent measurement and other technologies on its surface Intensified processing has greatly increased the service life of large-size automotive stamping dies. This technology has been provided to Shanghai Volkswagen Automotive Co., Ltd. and will bring huge economic benefits to the company. On May 18th, an expert group led by Academician Xu Zuyan, Academician Guan Bridge and Academician Zhou Shouyi, and the relevant person in charge of Shanghai Volkswagen Automotive Co., Ltd. heard a report on the appraisal and acceptance of the project at the Institute of Mechanics, and visited the laser. The smart manufacturing system saw a live demonstration of the mold hardening process. Experts agreed that the research results of the project have reached the international advanced level as a whole. Given that the "integrated laser intelligent manufacturing and flexible processing system" has major application prospects, the experts proposed that the project results should continue to be a breakthrough in the field of automobile mold laser surface hardening and other areas, and quickly promoted to other manufacturers to solve the large-scale long-disturbed automotive manufacturers in China Stamping die life problems, and then realize industrialization. The project developed a set of "integrated laser intelligent manufacturing and flexible processing system", integrated CNC kilowatt-class industrial solid-state laser, a wide range of high-precision 5-axis frame robot, rapid and intelligent mold surface measurement and surface reconstruction, molding process parameters Numerical and physical simulation software, space transformation and flexible transmission technology for high-power laser beams, laser surface enhancement technology and physics and mathematics model for automotive molds, bottom layer control, and CAx process database. The project has a combination of basic research and technological development, laser processing robot technology and laser manufacturing process mechanics, and has made a number of important progress and innovation. The system can meet the requirements of 3D laser processing and rapid prototyping, realize the intelligentization, flexibility and modularization of laser robot manufacturing and processing processes, and the digitization of information processes and the integration of control processes; it can provide technologies with independent intellectual property rights And equipment systems provide key technical support for the rapid development of automotive bodies. In the process of project development, the Chinese Academy of Sciences fully utilized its multidisciplinary advantages, extensively absorbed social resources, and conducted extensive and in-depth cooperation and exchanges with domestic and foreign counterparts to jointly overcome a series of difficulties. The project team has established close cooperation with Swedish Leroux University of Science and Technology, Shenyang Automation Institute, LNM, LHD Open Labs and other units, and has conducted basic and key technology research in related international frontier fields. At the same time, in order to meet the actual engineering needs of the stamping die surface strengthening, the project team communicated and closely cooperated with Shanghai Volkswagen Automotive Co., Ltd. to ensure that end-users agree with each stage of project development. As a national research institution, the Institute of Mechanics is aiming at the forefront of international scientific and technological development, conducting forward-looking, basic and strategic research in the field of advanced manufacturing and related mechanics science and technology in China, discovering new mechanical phenomena and accumulating innovative technologies that are urgently needed by the country. The foundation for the exploration and research of laser intelligent manufacturing process mechanics provides a necessary research platform for the leap-forward development of the manufacturing industry.
