Abstract

<B>MéTODO DE HIDROFORMAçãO DE UM COMPONENTE DE CHASSI DE VEìCULO<D> Um método de hidroformação de um elemento de canaleta (10) fechado que permite que o perímetro para seja aumentado, mas que mantém uma espessura de parede uniforme de um extremo ao outro, inclui a etapa inicial de empregar um elemento de canaleta fechado (10), tal como um tubo, dentro de uma primeira matriz de hidroformação (11) definindo uma primeira cavidade de matriz (12a, 13a). A superfície interna da primeira cavidade de matriz (12a, 13a) corresponde na forma transversal à superfície externa do tubo em parte ou em todo seu comprimento. Uma operação de hidroformação preliminar é realizada a uma pressão alta para expandir o tubo de acordo em conformidade com a primeira cavidade de matriz. O tubo expandido preliminarmente é disposto dentro de uma Segunda matriz de hidroformação (15) definindo uma segunda cavidade de matriz(16a, 17a). A superfície interna da segunda cavidade de matriz (16a, 17a) corresponde em forma transversal à forma final desejada para o tubo. Quando a segunda matriz de hidroformação é fechada, uma operação de hidroformação final é realizada a uma pressão baixa para deformar o tubo em conformidade com a segunda cavidade de matriz.
