Notes:
Numerical simulation can be successfully applied to evaluate product manufacturabilityand predict, while material wrinkling and splitting are associated with entry angle and pressure-padforce during sheet metal stamping process. In this paper, the influence of entry angle and pressure-padforce on deep-drawing thermal forming of TC1 titanium alloy was analyzed by using explicit dynamicfinite element software STAMPACK, two kinds of main invalidation, including wrinkling andsplitting, and obtained that the entry angle is an important factor for deep-draw thermal forming. Byanalyzing the forming operation and optimizing the entry angle and the pressure-pad force of the die,the best range of the entry angle and the suitable pressure-pad force without wrinkling were obtainedand splitting phenomena were controlled effectively. The researched results of numerical simulationprovided some parameters for die design
