摘　　要：介绍不均匀压下各种面内弯曲方式、成形特点、国内外研究现状及其应用前景 ;指出锥棍实现的这一过程具有柔性程度高、能耗低、精密度高、材料成形潜力发挥充分等显著优点 ,为了推动这一过程的研究与发展 ,还有待于对不均匀变形协调机理、过程参数的影响规律与成形极限等问题进行深入系统的研究。In-plane bending of strip metal under unequal compressing is an advanced forming process.The authors presented different kinds of In-plane bending types, process characteristics,research advancements and the perspectives of their applications at home and abroad. It is emphasized that the process execnted with two conical rollers has the marked advantages of good flexibility, low energy consumption, high precision and high material utilization, and can improve the forming limit greatly. In order to promote the research and development of the process,somekey technologies,such as the coordinate mechanism of unequal deformation,the influence of process parameters and the forming limits,will be stuclied continnously and systematically.
