FLANGE-FORMING SYSTEM FOR TUBE AND RELATED METHODS

摘要

In one embodiment, a system is provided for forming a flange at an end of a tube. The system includes a collar that is configured to surround the tube, and a first roller engaging the collar. A second roller is configured to cooperate with the first roller to rotate the collar and the tube and includes a depression configured to receive a radially inwardly protruding portion of the tube therein. A rotatable cam cooperates with the second roller and includes a cam surface configured to bend the end of the tube to thereby form the flange. The depression may be configured to restrict axial movement of the tube relative to the collar. The depression may include an annular recess that is circumferentially disposed about the second roller.
