大型板材离散多点成形工艺及装备研究

摘要

This paper presents a discrete multi-point forming process to deal with the problem occrring in the large-scale sheet metal stamping and introduces the structures of the mold and stamping bars applied in this process. Compared with the existing multi-point forming processes, such as poles flexible forming and misaligned stamping processes with swivel square press heads, the discrete multi-point forming process shows its advantages in the process of the large-scale sheet metal stamping.%针对大型板材的冲压成形问题，提出了一种离散多点成形工艺。介绍了此工艺中模具及柔性杆的结构。与已有的多点成形工艺---杆系柔性成形和活络方形压头非对压技术相比，离散多点成形工艺在大型板材成形过程中有其自身的优势。
