Investigation of Thickness Distribution Variation in Deep Drawing of Conical Steel Products

This study investigates the thickness variation behavior of deep drawing conical products under effect different forming parameters such as die wall inclination angle, punch velocity, sheet thickness, and metal type. Two types were used, low carbon (AISI 1008) galvanized steel sheets, 110 mm diameters circular blanks at 0.9 1.2mm formed by tooling set (punch, die, blank holder). The dies angles 70ᵒ, 72ᵒ, 74ᵒ where, velocity was 100, 150, 200 mm/min. Numerical simulation conducted using ABAQUS 6.14 where a dynamic explicit solver used to perform products. results show that maximum thinning occurs nose radius region thickening in sidewall are increased with increasing angle thickness. In regard type, Lankford coefficients r-value shows great role respect rolling (r-values direction). have shown good agreement between experimental numerical work discrepancy 5%.
