Abstract

Siebel’s analytic-experimental expression is used to determine the blank holder pressure in the process of deep drawing of cylindrical and conical cups. Its application in industry has given good results. This paper presents an adjustment of Siebel’s expression to the purpose of square cups deep drawing in oil hydraulic forming process. The experimental check up has also been performed including the application of this expression to the deep drawing of square cups of both rectangular and square cross section. The values of blank holder pressure obtained by the suggested expression are within the range of boundary limits of a good area.
