Abstract

Metodo per la realizzazione di un elemento metallico (2) per uno snodo, l'elemento metallico (2) presentando una testa (3) atta ad essere accoppiata ad un relativo corpo dello snodo, ed un gambo (4) integrale alla testa (3) e provvisto di un foro cieco (11) atto ad essere impegnato positivamente da un organo di comando dell'elemento metallico (2); il metodo prevedendo le fasi di realizzare uno spezzone (17) sostanzialmente cilindrico di materiale metallico, di deformare plasticamente a freddo un primo tratto terminale (50) dello spezzone (17), tramite almeno un primo gruppo di formatura (23, 24, 25), in modo da formare la testa (3), e di estrudere a freddo, mediante almeno un secondo gruppo di formatura (26, 27), un secondo tratto terminale (80) dello spezzone (17) per realizzare il gambo (4) ed il foro assiale cieco (11).[Figure 1 e 2]Method for making a metal element (2) for a joint, the metal element (2) having a head (3) adapted to be coupled to a relative body of the joint, and a stem (4) integral with the head (3 ) and provided with a blind hole (11) suitable for being positively engaged by a control element of the metal element (2); the method foreseeing the steps of making a substantially cylindrical piece (17) of metallic material, of cold plastically deforming a first terminal portion (50) of the piece (17), by means of at least a first forming group (23, 24, 25) , so as to form the head (3), and to cold extrude, by means of at least a second forming group (26, 27), a second terminal portion (80) of the piece (17) to make the stem (4) and the axial blind hole (11). [Figures 1 and 2]
