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。
Incremental sheet metal forming is a simple plastic mold plate processing one by one plastic, do not need a dedicated mold can be formed more complex parts, but also has a small forming force, high flexibility, especially for multi-species Small batch production methods, it has been the focus of scholars at home and abroad. In this paper, the development of sheet metal incremental forming is summarized in three aspects: incremental bending forming of sheet metal, incremental deep drawing bulging and incremental micro-forming. The development prospect of sheet incremental forming process is also discussed Looking forward, it is pointed out that it is the development trend to carry out theoretical innovation, develop new simulation software, explore new forming schemes and develop new incremental forming equipment.
