Abstract

EN UN DISPOSITIVO DE LAMINACION DE IMPACTO SE DISPONEN LOS EJES (2'',3'') DE LOS CABEZALES (2,3) DE RODILLO DE FORMA ESENCIALMENTE PARALELA CON RESPECTO AL EJE (1'') LONGITUDINAL DE LA PIEZA DE TRABAJO. CON ELLO SE CONSIGUE UN DESPLAZAMIENTO DE MATERIAL EN LA PIEZA (1) DE TRABAJO DE FORMA PRINCIPALMENTE PERPENDICULAR, TANGENCIAL CON RESPECTO AL EJE (1'') LONGITUDINAL DE LA PIEZA DE TRABAJO, SIENDO PREDOMINANTE A TRAVES DEL EFECTO (S{SUB,1}, S{SUB,2}) DE IMPACTO DE LOS RODILLOS (4,5) DE IMPACTO APLICADOS EN LOS CABEZALES (2,3) DE LAMINACION. A TRAVES DE ESTA DISPOSICION DE LOS CABEZALES (2,3) DE LAMINACION PUEDEN SER REALIZADOS LOS PROCESOS DE LAMINACION DE IMPACTO HASTA FORMAS DE ESCALONAMIENTO (1'''''') MARCADAS EN UNA ESPALDILLA (1'''') DE LA PIEZA (1) DE TRABAJO BAJO MANTENIMIENTO DE LAS VENTAJAS DE LOS PROCESOS DE LAMINACION DE IMPACTO CONOCIDOS, EN LOS CUALES SE CONSIGUE EL DESPLAZAMIENTO DE MATERIAL EN PARTICULAR EN EL EJE (1'') LONGITUDINAL DE LA PIEZA DE TRABAJO.
