PROCEDE POUR L'EMMANCHEMENT EN CROIX D'UNE PIECE CYLINDRIQUE DANS UNE PIECE TUBULAIRE, OUTILLAGE PROPRE A SA MISE EN OEUVRE, ET ENSEMBLE DE DEUX PIECES CORRESPONDANT

摘要

An assembly (10) formed of two parts pressed together in cruciform arrangement comprises a cylindrical part (11) and a tubular part (12). The tubular part (12) has a transverse hole (14) bordered by rims (18) extending toward each other. A spacer (16) in the form of a ring is inserted between the walls (15) of the tubular part (12), surrounding the region where the hole is to be formed. The rims are then deflected toward each other into engagement with the interior of the ring, the ring having a height equal to the distance between the walls (15). Thus, the ring (16) braces the tubular part (12) internally around the hole (14).
