Abstract (en)

[origin: EP2974807A1] A method and a machine for cold-forming a metal tubular element(1) for producing an exhaust terminal for burnt gas evacuation systems of internal-combustion engines, by first reducing the diameter of the tubular element (1) at one end and increasing it at the other end and then by using a press having a punch (3) and a die (2), the punch consisting of an inner cylinder (31) and of an outer sleeve (32) coaxial to each other and separated by a space (33) and the die (2) consisting of a cylindrical hollow.
