Shaft part rolling is an efficient and green near-net shaping technology offering many advantages, including high production efficiency, high material utilization rate, high product quality, and excellent production environment. In this paper, the features of shaft part rolling are introduced along with the working principles of two main shaft part rolling technologies, namely, cross wedge rolling (CWR) and skew rolling (SR). In relation to this technology, some R&D achievements gained by the University of Science and Technology Beijing are summarized. Finally, the latest developments in shaft part rolling are presented, including SR steel balls, precise forming of camshaft blank by CWR, SR phosphorous copper balls at room temperature, and CWR hollow axle sleeve. Although the shaft part rolling technology has been widely used in China, it only accounts for about 15% of applicable parts at present. Nevertheless, this technology has broad application prospects.

楔横轧齿轮轧制成形是一个全新的课题,在轧制过程中轧件的变形、温度场及力能参数都有待研究。将楔横轧技术与齿轮范成加工原理相结合,设计了楔横轧齿轮轧制的模具,给出了楔横轧齿轮轧制成形热力耦合本构模型,并在SuperForm平台对轧制成形过程进行了有限元模拟,获得了轧件在成形过程中的变形规律、温度场分布及力能参数变化等数据,详细分析了数值模拟结果,为进一步研究齿轮楔横轧制坯提供参考。
