An apparatus for forming a flange has a laminate component and a drum supporting the laminate component. A forming tool selectively engages the laminate component. A diaphragm member extends between the drum and the laminate component and selectively engages the forming tool. Movement of the diaphragm member deforms the laminate component away from the drum about an edge of the forming tool, and the laminate component maintains a substantially uniform thickness.

A working element operable to expand an end of a tube includes a main body configured to rotate about an axis, a plurality of roller supports movably coupled to the main body, the roller supports movable relative to the main body between a retracted position and an expanded position, and a plurality of rollers coupled to the roller supports such that a distance between a first roller of the plurality of rollers and a second roller of the plurality of rollers increases when the roller supports move toward the expanded position. The rollers are configured to be inserted into the end of the tube when the roller supports are in the retracted position, and the rollers are engageable with an inner circumference of the tube when the main body rotates about the axis to expand the end of the tube.

An expansion tool includes a housing, a motor supported by the housing and including a motor, a mandrel, and a drive mechanism configured to convert a rotational input from a motor shaft into translational movement of the mandrel. The expansion tool includes a first operating mode and a second operating mode. When the expansion tool is operated in the first operating mode, the drive mechanism is configured to reciprocate the mandrel between a retracted position and a first extended position. When the expansion tool is operated in the second operating mode, the drive mechanism is configured to reciprocate the mandrel between the retracted position and a second extended position different than the first extended position.

A pipe end processing device includes a female die and a male die. The female die has a through hole with one side thereof being radially increased, the through hole having the molding surface for forming the protrusion formed on an inner circumference on the one side of the through hole. The male die includes a metal core passed through the through hole of the female die and configured to be axially moved, and a tubular elastic body fitted on one end part of the metal core and protruding from the one side of the female die. The tubular elastic body is configured to be axially compressed by a movement of the metal core to radially expand by deformation thereby to press the surface to be processed of the pipe against the molding surface of the female die.
