Abstract

LA INVENCION SE REFIERE A UN CILINDRO DE EXTRUSION, CONSTITUIDO POR UNA ENVOLVENTE DE ACERO Y CASQUILLOS DE METAL DURO O MATERIALES COMPARABLES COLOCADOS EN AQUEL. CON LA INVENCION SE CONSIGUE CREAR UN CILINDRO DE EXTRUSION DEL TIPO DESIGNADO EN DETALLE AL PRINCIPIO, QUE PRESENTA UNA LARGA ESTABILIDAD, SIN QUE SE PRODUZCAN LAS AVERIAS INDICADAS. SEGUN LA INVENCION, ESTA PREVISTO QUE ESTEN DISPUESTOS VARIOS CASQUILLOS RETRAIDOS EN LA ENVOLVENTE DE ACERO, QUE EL PRIMER CASQUILLO ESTE AMARRADO AXIALMENTE ADICIONALMENTE AL AMARRE QUE RESULTA DE LA RETRACCION, Y QUE LOS OTROS CASQUILLOS ESTEN TENSADOS AXIALMENTE CONTRA EL PRIMER CASQUILLO. COMO VENTAJA ESENCIAL RESULTA QUE SE CREA UN CILINDRO DE EXTRUSION QUE TIENE UNA LARGA DURACION DE USO Y SE PUEDE EMPLEAR RAPIDAMENTE PARA DIFERENTES PROCESOS DE EXTRUSION, POR EJEMPLO EN EXTRUSIONADORAS DE PLASTICOS DE DIFERENTE COLOR.
