Method for making wing-shaped parts and resulting parts |
摘要 |
A method including the following successive operations carried out on a tube section: a) swaging one end to form at least two longitudinal strips folded down edge to edge and radially projecting outwards; b) cutting out the external projection of the strips to obtain at least two longitudinally separate tabs; and c) shaping the tabs into wings. The method can be used for making stirrups or fork joints at the end of a tubular part. It can also be used to produce semirigid axles or cradles for motor vehicles.
