发明名称 PROCESSO APERFEICOADO DE FABRICACAO DE RODAS METALICAS MONOBLOCO PARA VEICULOS
摘要 A process for manufacturing monobloc wheels for vehicles from a roughly shaped article having the shape of a cylindrical disc. A sequence of die stamping and rotary extrusion operations is carried out on the disc to arrive at the definitive shape, which does not require more than a few finishing operations by mechanical machining. These wheels which may in particular be made of light, aluminum-based alloys, are especially suitable for large tanker vehicles equipped with tubeless tires.
