Abstract:
     The invention relates to a method for shaping the vehicle hub and relative device. Wherein, it comprises following steps that casting blank; uniform processing; pre-shaping blank; compressing; compressing the front rim; expanding opening and folding the edge at the back rim. The invention is characterized in that: the casting blank via pre-shaping is made into hollow blank; the concave and convex moulds in the compressing step and the compressing front rim step are integrated, while the convex mound contains core axle; the compressing step compresses the hollow blank in the mould via core axle to obtain the cylinder element whose bottom has holes; the step that compressing front rim uses metal diversion to stuff and shape; the step that expanding opening and folding the edge of back rim uses integrated convex mould and separated concave mould to expand opening, fold edge an shape the back rim. The invention can simplify the process, reduce device number, reduce the shaping force, reduce the energy consumption, and reduce the producing cost. The invention is mainly used to produce aluminum and magnesium alloy hub.
