Abstract Scope |
This paper develops a novel flexible skew rolling (FSR) process to produce step shafts. The process includes four stages: radial rolling, rollers inclining, skew rolling and rollers levelling. Each roller has three freedoms (circle rotation, radial rotation and radial-feeding motion), which can manufacture different axles by programming different rollers’ movements that can achieve flexible rolling with same tools. A flexible skew rolling mill with dual-rotatable-shafts (DRM-80) was invented and manufactured, and feasibility experiments were performed at this mill. A shaft (total length 605 mm, minimum diameter 50 mm) was formed, and has well dimensional accuracy. The main forming defects include knurled pockmarks, helical grooves, side cavity, and diameter tolerance. The experimental FSR part is free from internal cracks by observing the transverse and longitudinal section. The study results verified that the novel flexible skew rolling process is positive and the new type DRM-80 mill is reliable. |
