Abstract
In-line adjustability of tools for high-volume forming processes could
improve yield while reducing lubricant use. This work presents an
improved design of an ironing punch with adjustable tool diameter and an
experimental study of its performance. Experimental results are
compared with numerical simulations conducted in LS-DYNA. Punch
retraction force of the new design was 68-85% lower than that of a
conventional punch, indicating a lower contact pressure and thus reduced
tool wear. The wall thickness of the ironed cups was adjusted by about
25 µm.
