Abstract
The high flexibility of die-less spinning has great potential for industrial applications. The severe wall thinning of die-less spinning can be suppressed using the ball-crown-shape roller (BCSR). However, the mechanical properties of the spun parts need to be investigated. In view of this, a truncated cone was formed by die-less spinning using the BCSR, and the mechanical performance and microstructure of the spun workpiece were investigated. The micro-hardness distribution on the spun cone was larger than that of the disk blank. The stress-strain curves from the tensile tests also emerged to have greater stress during the engineering strain of 0.05 to 0.225. The spinning results revealed that almost no wall thinning occurred on the die-less spun cone. The processing strengthening effect can be found on the die-less spun cone wall using the BCSR through micro-hardness and tensile tests. However, no grain refinement occurred in thickness direction after deforming. The processing strengthening mechanism was revealed as that the circumferential metal accumulation, which was caused by the unique shape of the BCSR, leading to greater compressive stress.
