Abstract

patente de invenção: método e aparelho para a fabricação de um membro dobrado. um membro dobrado possuindo excelente precisão dimensional é fabricado através de formação estável possuindo uma parte de temperatura elevada uniformemente na direção circunferencial de um tubo de aço e em uma região estreira na direção do tubo de aço usando um aparelho de fabricação do documento de patente 1. um membro dobrado é fabricado através do apoio de um tubo de aço 1 em uma primeira posição enquanto o alimenta, desempenhado aquecimento por indução do tubo de aço em uma segunda posição b com uma bobina de aquecimento por indução 14, o resfriamento do tubo de aço 1 em uma terceira posição c para formar uma parte da temperatura alta que se move na direção axial de tubo de aço 1, e variar tridimensionalmente a posição de um mecanismo de fixação 15 para o tubo de aço 1 em uma região d para aplicar um momento de dobradura à parte da temperatura alta 1a. quando a espessura da parede do tubo de aço 1 é de pelo menos 2,0 mm, a velocidade de alimentação v do tubo de aço 1 é feita de 5 a 150 mm/s, e uma corrente alternada de 5 a 100 khz é fornecida a uma bobina de aquecimento por indução 14 possuindo 1 enrolamento. quando a espessura da parede do tubo de aço 1 é maior que 2,0 mm e pelo menos 3,0, uma bobina de aquecimento por indução 14 possuindo 2 enrolamentos é usada, e a frequência da corrente f (khz) da corrente alternada fornecida para a bobina de aquecimento por indução 14 e a velocidade de alimentação v (mm/s) do tubo de aço 1 são ajustadas de modo a satisfazer f < 3000/v e f > 0,08 v, em que 5 khz <f< 100 khz, 5 mm/s <v<150 mm/s.
