Abstract (en)
[origin: EP0190636A2] The method of manufacturing sealed hollow male elements for hinge devices comprises the steps of shearing a segment off a drawn rod, and successively causing the material to flow laterally upwards such as by cold impact extrusion by means of a punch, to form a hollow body (5) of constant cross section having an open end. Thereafter, there is performed on said hollow body (5), as by impact with a die, a reduction of one portion at the open end (14), thus defining a hollow pin (8) having an open end (14). The latter is then stopped by press fitting a shaped body (13) thereinto.
