Abstract

Patente de Invenção: <B>"PROCESSO PARA A FABRICAçãO DE UM CORPO OCO OBLONGO E SUA APLICAçãO"<D>. A invenção refere-se a uma processo para a fabricação de um corpo oco oblongo de alumínio de dureza natural, como por exemplo AlMgMn, ou de uma liga de alumínio temperável por precipitação, como por exemplo AlMgSi1, assim como à aplicação de tais corpos ocos como parte integrante de suportes de mecanismos de translação na construção de veículos. Por ocasião da fabricação são ajuntadas pelo menos duas chapas de espessuras diferentes de parede a uma platina. Em seguida, esta platina está sendo transformada em um corpo oco e sua arestas longitudinais são unidas pela técnica de ensamblamento. A configuração definitiva do corpo oco efetua-se por remodelação de alta pressão interna hidráulica.Invention Patent: <B> "PROCESS FOR THE MANUFACTURING OF A HOLY OBLONG BODY AND ITS APPLICATION" <D>. The invention relates to a process for the manufacture of an oblong hollow aluminum body of natural hardness, such as for example AlMgMn, or of a precipitated aluminum alloy, such as for example AlMgSi1, as well as for the application of such hollow bodies as an integral part of supports of translation mechanisms in vehicle construction. At the time of manufacture, at least two plates of different wall thickness are attached to a platinum. Then, this platinum is being transformed into a hollow body and its longitudinal edges are joined by the assembly technique. The final configuration of the hollow body is carried out by remodeling the hydraulic high pressure inside.
