Abstract

UNA CARCASA DE DOBLE PARED, ESPECIALMENTE PARA CONVERTIDORES CATALITICOS DE VEHICULOS A MOTOR, DISPONE DE UNA CARCASA INTERIOR (1) Y UNA CARCASA EXTERIOR (2) QUE RODEA LA CARCASA INTERIOR (1) CONCENTRICAMENTE, ENCAJANDO LA CARCASA INTERIOR (1) Y LA CARCASA EXTERIOR (2) DE MANERA ESTANCA EN AMBAS CARAS, QUEDANDO SUJETA LA CARCASA INTERIOR (1) BAJO DEFORMACION POR COMPRESION POR UNAS CONSTRICCIONES DE LA CARCASA EXTERIOR (2) EN AL MENOS DOS REGIONES (4,5) EXTREMAS Y TENIENDO LA CARCASA EXTERIOR (2) UNOS REBAJES (11) HACIA LA CARCASA INTERIOR (1). PARA OBTENER UNA DISPOSICION DE CARCASAS DE ESTE TIPO, LA CARCASA INTERIOR (1) SE FORMA POR LAMINACION DE UNA CHAPA METALICA EN FORMA CILINDRICA O CONICA MIENTRAS SE MANTIENE UNA LINEA (8) DE SEPARACION, FORMANDOSE LA CARCASA EXTERIOR (2) POR LAMINACION DE UNA CHAPA METALICA EN FORMA CONICA O CILINDRICA Y UNIENDO LOS DOS BORDES (6,7) ENFRENTADOS PARA FORMAR UNA COSTURA, COLOCANDOSE LA CARCASA INTERIOR (1) DENTRO DE LA CARCASA EXTERIOR (2) Y DEFORMANDOSE PLASTICAMENTE LA CARCASA EXTERIOR (2) HACIA EL INTERIOR EN AMBAS CARAS SOBRE SU CIRCUNFERENCIA DE TAL FORMA QUE LA CARCASA INTERIOR (1) SE SOMETE A DEFORMACION POR COMPRESION, AL MISMO TIEMPO QUE LOS REBAJES (11) DE LA CARCASA EXTERIOR (2) ENCAJAN EN LA CARCASA INTERIOR (1).
