Abstract

LA INVENCION CONSISTE EN UN PROCEDIMIENTO DE FABRICACION DE MUELLES HELICOIDALES CURVOS A PARTIR DE MUELLES HELICOIDALES RECTOS, QUE COMPRENDE EN ESPECIAL UNA FASE DE CURVADO DE LOS MUELLES RECTOS DURANTE UN PERIODO DE TRATAMIENTO TERMICO. EL PROCEDIMIENTO SE CARACTERIZA POR EL HECHO DE QUE, PARA CURVAR LOS MUELLES, ESTOS SE MANTIENEN ALABEADOS DANDOLES SENSIBLEMENTE LA FORMA DE UNA PORCION DE ESPIRA DE HELICE A FIN DE PROPORCIONAR AL MUELLE UN CONTRADEFECTO ANTES DE REALIZAR LAS OPERACIONES ULTERIORES DE ACABADO. LA INVENCION ESTA RELACIONADA ASIMISMO CON LOS MUELLES FABRICADOS DE ACUERDO CON ESTE PROCEDIMIENTO Y CON LOS DISPOSITIVOS DE APLICACION DEL MISMO, QUE COMPRENDEN MEDIOS DE BLOQUEO DE POR LO MENOS LAS ESPIRAS DE EXTREMO DE LOS MUELLES, SUSCEPTIBLES DE PERMITIR UN BLOQUEO DIFERENCIADO DE DICHAS ESPIRAS, EN FORMA, POR EJEMPLO, DE UN SOPORTE (D SUB,2}) PROVISTO DE MEDIOS DE FIJACION (5A, 5B, 6A, 6B, 10A, 10B, 11A, 11B) PARA LAS ESPIRAS DE EXTREMO DE LOS MUELLES (R SUB,2}).
