Abstract

1. A method for obtaining by the hydraulic bending process, pieces of such shapes as T, or bulb sections from blanks having the shape of a tubular cross section or a similar shape, wherein one applies mechanical compression in the longitudinal direction of the blank and then hydraulic pressure within the latter so as to obtain a deformation of the blank in the transverse direction, the method being characterized in that it comprises at least one stage consisting in measuring, when the longitudinal compression attains a predetermined value, the corresponding value, the corresponding value of the internal pressure and/or of the transverse deformation of the blank, and in determining, depending on the said corresponding value, the subsequent relationship between the internal pressure and the longitudinal compression.
