板材柔性介质加压成形技术的研究现状

Research Status on the Sheet Flexible Medium Forming Technology

柔性介质成形是指利用如液态的水或油、粘性的高分子聚合物及固态颗粒等作为传力介质使板材加工成形的制造方法 .与传统工艺相比,板料柔性成形技术的工艺灵活度较高,兼具能保证质量、降低成本和缩短工序等优点,成为低塑性、难成形板材提高成形极限的有效途径之一.综述了液压成形、粘性介质成形和固体颗粒介质压力成形等代表性板材柔性介质成形方法近年来国内外的研究及发展现状,为航空航天、汽车制造等领域多品种、大批量、复杂形状零件的加工成形提供了技术指导.

The flexible medium forming is a manufacturing sheet method regarding the liquid water or oil, the viscous polymer or the solid particle, etc as the transmitting force medium. Compared with the traditional technolo- gy, the sheet flexible medium forming is a process that the process flexibility is higher, both to ensure quality, re- duce costs and shorten the process and so on. It becomes one of the effective ways to improve the forming limit of sheet with low plasticity and difficult forming. This paper generalizes the research and development situation of sheet flexible forming, such as hydraulic forming, viscous medium forming and solid particle medium forming in re- cent years, to provide a scientific basis for many varieties, large quantities and complex shaped parts in the field of aerospace, automobile manufacturing and other fields.
