【 摘 要 】

The paper describes cross wedge rolling with upsetting, a process in which axially symmetric parts with steps whose diameters are larger than billet diameters can be formed. Taking advantage of numerical modeling, the effect of such basic geometric parameters of the rolling process as the spreading angle, forming angle, reduction ratio, and rolling length on upsetting (defined by the diameter increase ratio) was determined. The paper also presents the results of experimental tests performed to roll a stepped shaft whose one step had a diameter half as large as that of the billet.
