Sažetak

This paper presents chosen results of theoretical and experimental research works on a new metal forming process of two-rib plates. The first part of the paper deals with forging technology of such products in a three-slide forging press, assuming two variants of the process: semi-open die forming and closed-die forming. In the further part of the paper, applying software simulations and making experiments for lead, the analysis of the assumed variants with consideration of optimal parameters of forming and present limiting phenomena was conducted. The phenomena disturbing the two-rib plates forging process were discussed in details. They include: plate buckling, overlapping and various types of forging deformation.
