Abstract

In order to be able to achieve a high degree of cold deformation in one working stage, the material of a cylindrical blank is forced radially outwards into the cavity of a die (14, 15) with symmetrical flow of the material in relation to its end faces by two rams (12, 13) which move towards one another. The symmetric flow of material is achieved by the fact that the rams are connected to the two die halves by elastic means (16, 17). The method is particularly suitable for the production of journal crosses (22).
