摘　　要：与薄壁回转体零件内压成形方法相对应的外压成形,由于受到失稳起皱的影响很少应用到大变形量零件的成形。粘性介质外压成形利用粘性介质物态特点和力学性能,不仅可以提高筒坯的稳定性,而且还可以适应起皱筒坯形状变化,在一定压力场作用下消除褶皱,从而有效解决失稳起皱对外压成形质量的影响。主要介绍了粘性介质外压成形基本原理,总结了介质性能、加载方式、筒坯尺寸特征等因素对失稳起皱过程的影响,以及在薄壁回转体零件中的应用情况,并对存在的问题及发展趋势进行了总结与展望。The outer pressure forming method corresponding to the inner pressure forming of thin-walled tube parts is rarely applied to the forming of large deformation parts due to the influence of instability and wrinkling.Viscous outer pressure forming uses the physical characteristics and mechanical properties of the viscous media to not only provide the stability of the tube,but also adapt to changes in the shape of the wrinkling tube,and eliminate wrinkles under a certain pressure field,thereby effectively solve the outer pressure influence of instability and wrinkling during forming on the quality of outer pressure forming.This paper mainly introduces the basic principle of viscous outer pressure forming,summarizes the influence of medium properties,loading methods and tube size on the instability wrinkling process,as well as the application of viscous outer pressure forming in thin-walled tube parts,and summarizes and looks forward to the existing problems and development trends.
