Abstract
In order to reveal flow laws of impeller parts in die forging process, the deformation and flow of different shape blank forming process was studied using the finite element method. The results show that cylindrical shape can be formed more easily; stepped shape billet occurs mainly in the end. Compared with cylindrical shape, the mode cavity of blade parts fills more easily, and the uniformity of metal flow also increases significantly. The dimensional accuracy and performance meet the design requirements using stepped shape to manufacture impeller through experiment process analysis verification.
