1. a manufacture method for Al-Mg-Si alloy wheel hub, is characterized in that, comprises the following steps:

  • The first step, gets the raw materials ready;

    By the alloy hot rolled disc-shaped blank of making of Al-Mg-Si;

    Second step, preheating;

    Disc-shaped blank is preheated to 450 ℃



    500 ℃

    ;

    The 3rd step, forge hot;

    At 450 ℃



    500 ℃

    temperature, by forging press, disc-shaped blank is carried out to forge hot, form plate-like blank, make wheel hub preliminarily forming;

    The 4th step, quenches;

    Plate-like blank through forge hot is carried out to Quenching Treatment;

    The 5th step, mould pressing;

    Plate-like blank through quenching is shaped by spinning machine shear spinning, forms hollow rotary body wheel hub blank;

    The 6th step, solid-solution and aging heat treatment;

    By through the wheel hub blank heating to 500 of mould pressing ℃



    580 ℃

    , be incubated quenching after 1~

    4 hour, then put into aging furnace and be heated to 120 ℃



    220 ℃

    , be incubated 2~

    8 hours;

    The 7th step, machined and surface treatment;

    Wheel hub blank through solid-solution and aging heat treatment is carried out to machined and surface treatment, obtain aluminium alloy wheel hub finished product.
