  • ZONING CLOSED-DIE EXTRUDING DEVICE AND METHOD
    Publication number: 20120090375
    Abstract: A zoning closed-die extruding device comprises a closed female die and a male die. which is disposed in a longitudinal direction and configured to be mated with a closed cavity of the closed female die to extrude a blank. The male die comprises an extruding shaft portion and a stamp-extruding head portion, which is connected with the extruding shaft portion and disposed below the extruding shaft portion. A cross-sectional area of the stamp-extruding head portion perpendicular to a longitudinal axis of the closed female die is smaller than that of the extruding shaft portion perpendicular to the longitudinal axis of the closed female die. The male die is configured to rotate about the longitudinal axis of the closed female die so that the blank is sequentially and zonally deformed by the stamp-extruding head portion inside the closed cavity of the closed female die.
