Abstract
Patente de Invenção:<B>"PROCESSO E DISPOSITIVO PARA A FABRICAçãO DE EIXOS DE CAMES"<D>. Para uma fabricação com baixos custos de componentes oblongos de corpos ocos (5), especialmente eixos de cames, não só com economia de ferramentas e passos de trabalho mas também com aumento da produção, são deformados em uma só peça abaulamentos, respectivamente cames (6) com a deformação de alta pressão interna de um eixo oco (5) de tal maneira que os abaulamentos (6) quando à sua deformação e/ou posição podem ser deformados em vários passos.Invention Patent: <B> "PROCESS AND DEVICE FOR THE MANUFACTURE OF CAMS AXLES" <D>. For low-cost manufacturing of oblong hollow body components (5), especially cam shafts, not only with economy of tools and work steps but also with increased production, bulges are deformed in one piece, respectively cams (6 ) with the internal high pressure deformation of a hollow shaft (5) in such a way that the bulges (6) when deformed and / or positioned can be deformed in several steps.
