Process (20) for manufacturing a wheel rim (1) in light alloy including the following operations: providing (21) a rough wheel rim in light ally, comprising a wheel disc (2) and an annular portion (3), the annular portion (3) including a first (4I) and a second (4e) bead defining a drop well ( C) having a first profile; processing (23) the rough wheel rim, modifying the first profile in order to obtain a second profile being of a lower thickness than the first profile, at least at an intermediate portion (C1) of the drop well ( C), characterised by including a finishing operation (25) of a surface of the second profile intermediate portion by means of a compression action of said surface, the finishing operation leaving the low thickness substantially unchanged.
L'invention porte sur un procédé (20) de fabrication d'une jante (1) en alliage léger, ce procédé consistant à : produire (21) une ébauche de jante en alliage léger comprenant un disque (2) et une partie annulaire (3), cette partie annulaire (3) étant formée d'une première (4i) et d'une seconde (4e) nervure formant un puits (C) présentant un premier profil ; traiter (23) l'ébauche de jante, modifier le premier profil de façon à obtenir un second profil dont l'épaisseur est inférieure à celle du premier profil, au moins au niveau d'une partie intermédiaire (C1) du puits (C). ce procédé est caractérisé en ce qu'il comprend une opération de finition (25) d'une surface de la partie intermédiaire du second profil par compression de ladite surface, cette opération de finition ne modifiant pratiquement pas le peu d'épaisseur.
