Abstract

PROCEDIMIENTO PARA CONFORMAR PIEZAS DE EMPALME, DE ELEMENTOS TERMOPLASTICOS. BASADO EN QUE LA PARTE TERMINAL ESTRECHADA DE LA PIEZA DE EMPALME PRECONFORMADA ES POSCONFORMADA EN LA FORMA FINAL DESEADA, TRAS LA DEFORMACION ELASTICA Y ANTES DEL ENFRIAMIENTO TOTAL. PARA LO CUAL EL ELEMENTO DE POSCONFORMACION ESTA EQUIPADO CON UNA CAMARA INTERNA DE ENFRIAMIENTO, PARA OBTENER UN DESCENSO DE TEMPERATURA RAPIDO Y ACORTAR EL PROCESO; EL DISPOSITIVO INCLUYE UN MACHO DE CONFORMACION DE FORMA CILINDRICA CON UN NERVIO PERIFERICO, UN CASQUILLO DE CONFORMACION Y UN ANILLO DE CIERRE, DESPLAZABLES ENTRE ELLOS Y RESPECTO A UN BAJO; TAMBIEN DISPONE DE CAMARAS DE CALDEO Y REFRIGERACION EL MACHO DE CONFORMACION, EN EL ELEMENTO DE POSTCONFORMACION Y EN EL ANILLO DE CIERRE. USADO EN EL EMPALME DE MATERIAL TERMOPLASTICO.
