Abstract
Deep drawing involves conversion of flat thin sheet metal blanks into parts of desired shape. In the present investigation, the process parameters of warm forming are compared with those of Hydromechanical deep drawing. Warm deep drawing process of circular blanks in Ironing stage is investigated using a 20 T hydraulic press. Hydro-mechanical deep drawing is a process for producing cup shaped components with the assistance of a pressurized fluid. There is an increase in the drawability of low Carbon steel by increasing the oil gap (gap between punch and die) but to make exactly cylindrical shape, the cup is subjected to ironing in the later part of drawing operation. Thickness distribution which describes the quality of the drawn cup is compared in both warm and Hydromechanical deep drawing using experiments and finite element simulations. Keywords- Warm forming,Hydromechanical, deep drawing, Drawability.
