Abstract
"PROCESSO E DISPOSITIVO PARA O ENTALHE DE TUBOS E TUBO OBTIDO PELO EMPREGO DO PROCESSO". A invenção relata um método de entalhe de tubos. O método inventivo é caracterizado pelo fato de que compreende um movimento para frente e para trás de pelo menos um cilindro de prensa. Durante o referido movimento, o cilindro acima mencionado aplica pressão localmente na parede do tubo (1) e deforma plasticamente o mesmo. O movimento do cilindro de pressão é produzido por uma combinação de pelo menos dois outros movimentos, a saber: um primeiro movimento para frente e para trás essencialmente retilíneo, durante o qual o cilindro rola contra a parede do tubo (1); e um segundo movimento para trás, a resultante do qual é essencialmente perpendicular à direção do primeiro movimento. Deste modo, O tubo (1) é plasticamente deformado em pelo menos dois movimentos do cilindro de prensa.
