Abstract
Method and device for obtaining elbows in tubes, curved in the form of a fork, by means of a punch or die and semi-traits, characterized in that the curve of the tube, preferably heated homogeneously, is sustained, during the shaping operation, by the semimatrices in the inner region of the curve, while the entire external region of the curve and the outside of the rectilinear branches thereof are subject to the action of an animated punch or die of a translation movement in the semimatrix, in such a way that, at the end of this movement, these parts of the curve are surrounded by the punch, and the shaping operation is the result of the translation displacement of the punch in the semimatrices.
