| Abstract: | Drawing is an important process of large shaft forgings. Aiming at drawing process in the forging process, a new anvil was designed to to improve the stress and strain state of workpiece in the drawing process, as well as the internal quality of forgings. The effects of anvil＇s angle and anvil width ratio on forging deformation and inner stress were studied by applying finite element analysis software deform-3 D, and the contrast simulation results were listed. Then the basic parameters of the anvil were defined. |
