板料增量成形的研究进展

板料增量成形是采用简单模具对板料进行逐次塑性加工的一种工艺,不需要专用的模具就可以成形较为复杂的零件,同时还具有成形力小、柔性高的特点,特别适合多品种小批量零件的生产方式,因此得到国内外学者的重视。本文重点从板料的增量压弯成形、增量拉深胀形、增量微成形3个方面对板料增量成形的发展进行综述,还对板料增量成形工艺的发展前景进行了展望,指出进行理论创新、开发新的模拟软件、探索新的成形方案、开发增量成形新设备是发展趋势。

Research development of incremental sheet metal forming

The incremental sheet metal forming process, in which sheet metal is being formed step by step with simple die, is defined as one kind of plastic deformation technology. Without the specific die, a complex shape part can be formed in this method. Its favorable feature is small forming load and high flexibility. This technology is particularly suitable for multi-variety and small-batch production of parts, so that more attentions are paid to it by the international community. The development of incremental sheet metal forming was mainly summed and discussed in the incremental bending forming, incremental forming of deep drawing and bulging shape, as well as incremental micro-forming. Finally the future development on the incremental sheet metal forming process was prospected and it was pointed out that the four areas-theoretical innovation, the development of new simulation software, the exploration of new forming program and the development of new forming equipment are the the developing trends at present.
