METHOD AND DEVICE FOR FORMING, BY FLOSPINNING, A TUBE, IN PARTICULAR A SILENCER OR EXHAUST LINE CATALYST CASING

摘要

The invention concerns a method for forming, by flospinning, a tube, in particular a silencer or exhaust line catalyst casing (1) for a motor vehicle, characterized in that it consists in: moving the casing (1) relative to the flospinning tool (9) along a direction X parallel to the axis (14) of said casing (1), but as well along perpendicular directions Y, Z; then imparting to said casing (1) a first rotation about an axis Y perpendicular to its axis (14), and a second rotation about said axis (14) and/or about an axis Z perpendicular to the plane passing through the axis (14) of said casing (1) and the first rotation axis Y. The invention also concerns a device for implementing said method.
