摘　　要：齿形轴类零件是各种机械装备中传动和承载的关键零部件,传统的机械加工制造方法浪费材料、机械性能和表面质量差、生产效率低,采用冷体积精密成形工艺可以克服上述缺点。本文分析了齿形轴类零件各种加工成形工艺;介绍了冷体积成形技术的原理、特点、研究现状和发展趋势;重点探讨了齿形轴类零件冷敲精密成形工艺原理、技术特点和装备研发的最新进展,以利于这种高效少无切削工艺和装备的推广应用。Tooth-like shaft part is an important driving and load carrying element in various equipments. Traditional manufacturing methods used for these parts expose some disadvantages such as wasting materials,low production ef-ficiency,poor mechanical behavior and surface quality. But these shortcomings could be overcome by cold accurate forming technology. In this paper,various methods used for manufacturing tooth-like shaft parts are analyzed. The principle,characteristic,research status and development trend of cold accurate forming technology are introduced. The process principles,technical features and new equipment development of cold striking technology for tooth-like shaft parts are mainly investigated. All of these are beneficial for the application of such advanced technology.
