文摘

In hydromechanical deep drawing (HDD), a chamber of fluid replaces the matrix and the final form of part is determined based on the form of rigid punch. Allowable working zone in this process indicates the applicable range of chamber pressure versus drawing ratio to achieve a rupture-free drawing. In this article, the HDD of the square parts was studied using the finite element method (FEM) and the effect of different parameters of the process such as pre-bulging pressure, chamber pressure, and friction coefficient on the working zone was investigated. The results showed that increasing of the friction between blank and die or blank and blank-holder confines the working zone, while by increasing of the friction between blank and punch, the working zone becomes larger. A study was also carried out using experimental setup for verifying the FEM results. Finally, the numerical results were compared with experimental ones.
