摘　　要：首先,简要介绍了径向锻造机组的结构特点和工作原理,总结了近半世纪来国外机械驱动、液压驱动、机液混合驱动径向锻造机的锤头驱动方式的主要研发进展,对其典型产品的相关技术特点和产品型谱进行了分析对比。然后,详细介绍了径向锻造机在我国的发展概况和技术现状,指出全液压式径向锻造机及其生产线的全面国产化是我国锻压行业的迫切需要。故障预测与健康管理、智能制造是径向锻造机锤头驱动方式发展的主旋律,薄壁无缝钢管的锻打极限问题和更高锻打频次的追求将促使机械式径向锻造机锤头驱动方式由偏心轴滑块结构向双叶驱动轴结构演变。Firstly,the structural characteristics and working principle of radial forging machine were simply introduced.The main progresses in the research and development of hammer driving methods of mechanical drive,hydraulic drive and mechanical-hydraulic hybrid drive for radial forging machine abroad were summarized in the past half century,and the related technical characteristics and product spectrum of the typical products were analyzed and compared.Then,the development and technical status of the radial forging machine in China were introduced in detail.The results show that the hydraulic drive for radial forging machine and its full localization of production lines is the urgent need of forging industry in China.Fault prognostics,health management and intelligent manufacturing are the main theme of the development of hammer driving mode for radial forging machine.Furthermore,the forging limit problem of thin-walled seamless steel pipe and the pursuit of higher stroke rate can promote the evolution of the hammer driving mode of mechanical radial forging machine from the eccentric shaft slider structure to the double blade drive shaft structure.
