The Chinese Academy of Sciences defeats difficult problem of technology of mould of solution car punch

Project of innovation of knowledge of Chinese Academy of Sciences is major project " compositive change laser intelligence to make reach flexible treatment system " make, the project of innovation of knowledge of the first batch of the Chinese Academy of Scienceses that by the the Chinese Academy of Sciences mechanical institute manages is major project " compositive change laser intelligence to make reach flexible treatment studies " , it is the project group of the chief scientist 3 years to tackle key problem assiduously via Yu Gang's researcher, development goes domestic head to cover " compositive change laser intelligence to make reach flexible treatment system " , be aimed at the punch mould service life that restricts industry of our country automobile to develop further short, uphold charge tall this one difficult problem, use laser and material interaction principle to combine intelligence to measure wait for a technology to undertake to its surface aggrandizement is handled, improved the service life of mould of large car punch substantially thereby. This technology already provided limited company of Shanghai masses car, will bring enormous economic benefits for the enterprise. On May 18, the appraisal that chief listened to this project in mechanical institute related the expert group that is a group leader in order to make Zu Yan academician, academician shutting the bridge, Zhou Shouhuan academician and limited company of Shanghai masses car, check and accept a seminar, visited this laser intelligence to make a system, the scene that watched mould aggrandizement process demonstrates. The expert thinks consistently: Whole of achievement of this project research achieved international advanced level. In view of " compositive change laser intelligence to make reach flexible treatment system " have great applied perspective, the expert puts forward project achievement to should continue to be breach with the domain such as aggrandizement of surface of car mould laser, popularize other manufacturer quickly, solve the problem of service life of large punch mould that puzzles manufacturer of our country car for a long time, realize industrialization then. Project development goes " compositive change laser intelligence to make reach flexible treatment system " , compositive laser of solid body of industry of class of numerical control kilowatt, big range high accuracy robot of type of 5 axes frame, fast intelligence measures mould surface to reframe with curved surface, the mould shapes the numerical value of craft parameter and physical simulation software, the space that high power stimulates beam of light alternates and flexible transmission technology, technology of aggrandizement of surface of car mould laser and physical maths model, rock-bottom control and CAx process database. The project has technology of robot of basic research and union of technical development phase, laser beam machining and laser workmanship the distinguishing feature that mechanical photograph combines, obtained multinomial and significant progress and innovation. This system can satisfy the requirement that laser beam machining mixes 3D to shape quickly, implementation laser robot makes the intelligence with treatment process change, flexible change and modular, and the digitlization of information process and those who control a process is compositive change; Can provide the technology that has own intellectual property and equipment system, for car automobile body rapid development provided crucial technology support. In project development process, produced the integrated advantage of across of much discipline of the Chinese Academy of Sciences adequately, absorb social natural resources extensively, had the collaboration of extensive development and communication with domestic and international person of the same trade, captured jointly a series of difficulty. Project group and Sweden strap automation of university of Lv Ao science and technology, Shenyang this place, place LNM, LHD opened the unit such as the lab to build clasp, foundation and crucial technology research were begun in domain of relevant international forward position. In the meantime, to satisfy aggrandizement of punch mould surface this one actual project needs, project group and limited company of Shanghai masses car are communicated at any time, cooperate closely, made sure terminal user develops the self-identity of each phase to the project. Mechanical institute regards national level as the research organization, point the forward position that international science and technology expands, begin our country advanced make the look up before reaching domain of relevant and mechanical science and technology gender, foundation sex and strategical research, discover new mechanical phenomenon accumulates innovation technology, for the laser intelligence workmanship that the country is badly in need of mechanical exploratory study lays a foundation, it is those who realize manufacturing industry to span type development provided necessary research platform.
