Abstract

Patente de Invenção: <B>"TUBOS E FORMAS"<D>. A invenção tem como objeto um processo de realização por hidroconformação de uma picagem inclinado a partir de um tubo (3) metálico, no qual coloca-se o tubo (3) em uma matriz (10) que possui uma impressão equipada com uma derivação (13) que corresponde à forma desejada da dita picagem, injeta-se no tubo um fluido sob alta pressão e simultaneamente exerce-se uma impulsão sobre cada extremidade do dito tubo para forçar o metal a fluir dentro dessa derivação. Desde o início da realização da picagem, retém-se sua superfície frontal (3a) na derivação de acordo com uma superfície paralela ao eixo do tubo (3) e, em um momento escolhido no decorrer da formação da picagem, orienta-se a superfície frontal da picagem de acordo com uma superfície perpendicular ao eixo dessa picagem. A invenção também tem como objeto um dispositivo para a execução desse processo.
