Abstract

Procedure for the manufacture of fittings, of the type characterized in that the end of the fitting that is constituted with a pair of coaxial tubular elements is produced by introducing a preformed block of cold extrudable material, crossed by an axial hole, inside a die closed by one end, introducing into the axial hole of the block a spike that protrudes from the block itself in correspondence with the end of the block that is directed towards the open end of the die and violently hitting said end of the block in the axial direction with a tubular punch having an internal transverse dimension greater than the transverse dimension of the axial hole of the block and an external transverse dimension less than the transverse dimension of the die cavity, so as to cause the cold extrusion of two developing tubular elements, the innermost, between the inner wall of the punch and the protruding part of the to spike and, the most external, between the external wall of the punch and the internal wall of the die.
