Abstract
Commercially pure titanium (CP Ti) is paid much attention to for its lightness, high specific strength and property of anti-rust. Because of hexagonal close-packed (HCP) crystal structures, CP Ti shows low ductility at room temperature, and requires thermal activation to increase its ductility and formability. In this paper, the FEM soft ware DEFORM-3D is used to simulate the square cup deep drawing of pure titanium metal sheet at elevated temperatures. A finite element method is also used to investigate the effective stress distribution and maximum forming load under various process parameter conditions, including the profile radius of die, the clearance between die cavity and punch and the blank holding force. Furthermore, in order to form a uniform cup height of products, a reverse forming method for obtaining the initial blank’s shape according to the forward square cup drawing simulation is proposed.
