大型板材离散多点成形工艺及装备研究

Analysis and Study of Discrete Multi-point Forming Process for Large-scale Sheet Metal

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。

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.
