板材成形中的技術革命

Revolutionary Developments in Sheet Metal Forming Technology

  • 摘要: 提出板材成型技術中存在技術革命。第一次技術革命以板材成形從工場走向工廠為標志;第二次技術革命以實驗成形性評定和實驗變形分析為標志;第三次技術革命以理論成型性評定及成型CAD/FMS的出現為標志,它是原材料工業迎接材料科學技術革命的一條有效途徑。
    板材成型成為一個科學領域必然要與板材生產密切結合,這就提出了發展板材系統工程的需要。板材系統工程的基本內容是:(a)板材生產,(b)板材成型,(c)板材冶金過程與板材成形過程的協同。
    回顧計算機輔助成型性分析和工藝優化的發展,提出了計算機輔助戰形性分析體系、計算機輔助成形工藝優化體系及板材成型學科體系并給出了這三種體系的框圖。

     

    Abstract: The research and development of sheet metal forming is thought as a good way through which metallurgical industry will be developed to meet the needs of the revolution in material science and technology. Three stages of revolutionary developments in sheet metal forming industry have been differenciated. The mark of the first revolution is that sheet metal forming was operated with machines and dies in a factory instead of manual operation in a workshop) the second revolution is indicated by the assessment of process and formability derived from experiment,the study of theoritical formability and the foundation of cAE/FMS are the indications of the third revolutionary development in sheet metal forming. Since sheet metal forming, as a engineeing science, has got to marry sheet metal processing, a concept of SYSTEM ENGINEERING in sheet Metal (SESM) has been put forward,which covers: (a) sheet metal processing; (b) sheet metal forming;(c) coupling between metallugical processing(e.g. make-ing process, rollng process etc.) and forming process of metal.
    Computer-aided analysis of formability and computer-aided optimization and modelling of forming process are reviewed, and their schedules are illustrated. Furthermore, the comprehensive structure of sheet metal forming as a independent subject is presented.
