Research on Single Pass Deep Drawing Spinning Formability of Cup-Shaped Parts

Abstract:

The deep drawing spinning (DDS) formability of metal material refers to the ability to produce an opened hollow part with a circular blank through DDS without fracture or wrinkling defect. The cup-shaped parts of DP600 were selected as the research object, the coefficient m=d/D₀ was put forward as the evaluation index of DDS formability, and the minimum coefficient without the occurrences of wrinkle and fracture is defined as the limit DDS coefficient m_lim. The single pass DDS formability of cup-shaped parts was investigated experimentally and the influences of blank thickness, roller feed rate and roller fillet radius on the DDS formability were discussed in detail. The results show that the DDS coefficient decreases with the increasing of blank thickness; fracture or wrinkling occurs easily when the roller feed rate is excessively large or excessively small; the large roller fillet radius is helpful to improve the DDS formability of metal material.
