  • Method for deforming a tube near one of its ends and tool used in this method
    Patent number: 6792782
    Abstract: The invention concerns a method using steps of placing a tube in an opening matrix having an impression corresponding to the desired final external shape; inserting the end of the tube into a cavity of a shaping component, the cavity having a base, a side wall with adapted shape, and an opening opposite the base; pressing the end of the tube against the base of the cavity, leaving a clearance between the opening of the cavity and the matrix; applying an essentially axial force on the end of the tube, the zone application of the force rotating about a longitudinal axis of the tube thereby causing gradual deformation of the tube; withdrawing the end of the deformed tube outside the cavity of the shaping component and outside the matrix.
