1. a kind of magnesium alloy auto hub molding machine, it is characterised in that:

  • the carrying mould machine including carrying wheel hub semi-finished product blankStructure, roller disk group, speed control system and the heating system that carrying mold mechanism periphery is set;

    The carrying mold mechanism includes mouldCore, the pressure-bearing pallet for carrying wheel hub semi-finished product blank, the carrying driving spindle for driving pressure-bearing pallet and for wheel hub halfThe pressurization disk of finished product blank application axial compressive force;

    The roller disk group includes at least one roller disc mechanism;

    The roller disc mechanism includesThe servo mechanism that outer edge is laterally and axially moved in the platen and driving platen of circular arc;

    Roller disc mechanism further includes driven rollerThe free-wheeling system of platen rotation makes platen squeeze digging on wheel hub semi-finished product blank and forms a positioning groove by the free-wheeling system;

    The speed control system includes for the linear velocity angular rate control unit of platen in roller disc mechanism and for driving spindleStrain rate controller;

    The control precision of linear velocity angular rate control unit is 10-5~10-3, the control of strain rate controllerPrecision is 10-3~10-2S-1

    The outer edge circular arc of each platen in the roller disk group be in different size, circular arc respectively with finished productEach circular arc of the shape of automotive hub is consistent;

    Roll-in disk diameter according to finished automotive hub diameter choose, adjusting range be ¢

    100 ~¢

    450mm;

    Heating system is far infrared heating system, including additional hot systems and interior heating system.
