Abstract
Patente de Invenção para "PROCESSO DE HIDROFORMAçãO COMPRESSIVA DE UMA PEçA DE TRABALHO TUBULAR". A invenção se refere à formação de uma peça de trabalho tubular (19) por meio da aplicação de pressão de fluido (21) ao interior da peça de trabalho (19) e encerramento da peça de trabalho pressurizada (19) em uma matriz (11, 12) que tem uma cavidade da matriz (18). Uma porção de toda cavidade (18) tem sua periferia interna menor do que a periferia externa da peça de trabalho (19). Isto sujeita a peça de trabalho (19) à formação compressiva.
