带筋薄壁构件成形制造技术的发展与展望

As key structural parts of aerospace and weaponry, the integrated manufacturing of thin-walled components with ribs is an effective method to achieve the lightweight of high-end equipment and improve its performance. According to the development of thin-walled components with ribs, it was classified in this paper. Based on panel and cylindrical/ring parts, the research progress of manufacturing technology of two types of ribbed components were summarized. With regard to the rib-web parts, the development history of traditional forming technology, integral near-net plastic forming technology and local loading near-net plastic forming technology were reviewed. Then, the above three kinds of technology of processing theory, technology and tooling were discussed, and the characteristics of manufacturing and the differences in component performance were compared. For the cylindrical/ring parts with ribs, the latest research progress of extrusion, spinning and envelope forming on component manufacturing were reviewed, and the technical characteristics and development potential of various processes were compared. Based on the analysis of the above research, the development trend and technical challenges of manufacturing technology of thin-walled components with ribs were summarized.
