Abstract

Abstract: With the increasing demand for personalized customized products and the higher and higher requirements for the speed of product upgrading, metal flexible manufacturing technology, as the cutting-edge technology of manufacturing technologies in the world today, has received more and more attention and promotion from the industry. As an important branch of flexible manufacturing technology, flexible forming technology refers to a certain degree of plastic deformation of the blank in a specific direction by controlling the three-dimensional motion trajectory of the forming tool under the condition of no die or less use of die (only using general die), so as to obtain the required mechanical properties, shape and size. Compared with the traditional plastic forming technology, flexible plastic forming technology has unique advantages in the trial production of new products, the production of multi-varieties and small batch products, and the research of complex metal components. In recent years, with the deepening understanding of flexibility and flexible manufacturing, the connotation of flexible plastic forming technology has been enriched and developed constantly, many new flexible plastic forming technologies and successful application examples have emerged. the state-of-arts of flexible plastic forming technologies have been overviewed from the point of target metal component structure types in this paper. The flexible plastic forming technology is divided into tube, profile and sheet metal flexible forming technology. The application progress, technical principle and latest development of flexible forming technology for each target component type are summarized.

Key words: 3D spatial movement trajectory, flexible forming technology, tube, profile, sheet mental
