Abstract: On the basis of the real stress and strain which have been obtained, the distribution and the characteristic of contact stress are first obtained and analyzed according to the force analysis on the every contact region of conical part during deep drawing. Simultaneously, the above results are examined by considering the force equilibrium of the punch and blank holder which are separated respectively. It is of great significance for further creating more accurate models of mathematics and mechanics, discovering the mechanism of conical part press forming, and realizing intelligent control forming process.

Key words: Conical parts, Contact stress, Deep drawing, Intellectualization
