Selecci\u00f3n de acero para herramientas para matrices de conformado de rollos<\/h1>\n\n\n\n

El conformado por laminaci\u00f3n es un proceso continuo de trabajo en fr\u00edo en el que una tira o l\u00e1mina se dobla progresivamente a trav\u00e9s de varias estaciones de laminaci\u00f3n. La herramienta permanece en contacto constante con el material, y la deformaci\u00f3n se distribuye en lugar de concentrarse.<\/p>\n\n\n\n

Esta condici\u00f3n de operaci\u00f3n determina c\u00f3mo fallan las matrices de conformado por rodillos. El mecanismo dominante no es el impacto ni la fractura, sino la degradaci\u00f3n de la superficie bajo contacto y deslizamiento sostenidos. El desgaste abrasivo altera gradualmente el perfil del rodillo, lo que provoca una desviaci\u00f3n dimensional en la secci\u00f3n conformada. Al mismo tiempo, el desgaste adhesivo \u2014que generalmente se observa como rozamiento o rayaduras superficiales\u2014 da\u00f1a tanto la superficie de la herramienta como el acabado del producto.<\/p>\n\n\n\n

Por lo tanto, la selecci\u00f3n del material est\u00e1 determinada por la eficacia con la que el acero para herramientas controla estos dos mecanismos durante largos ciclos de producci\u00f3n.<\/p>\n\n\n\n

L\u00f3gica de selecci\u00f3n<\/h2>\n\n\n\n

El requisito principal es una resistencia al desgaste estable bajo contacto deslizante continuo. En aplicaciones con alta tensi\u00f3n de la banda o fuerte resistencia al conformado, la superficie del rodillo debe mantener su geometr\u00eda a lo largo del tiempo. Esto lleva a seleccionar aceros para herramientas con alto contenido de carburo cuando el desgaste abrasivo es el factor limitante.<\/p>\n\n\n\n

Sin embargo, una mayor resistencia al desgaste reduce la resistencia al astillamiento bajo carga. Si bien el conformado por laminaci\u00f3n no se basa principalmente en impactos, la presi\u00f3n localizada, la desalineaci\u00f3n o la variaci\u00f3n de la banda pueden generar concentraciones de tensi\u00f3n. Si el material carece de la tenacidad suficiente, pueden producirse astillamientos en los bordes o agrietamiento superficial antes de que el desgaste se vuelva cr\u00edtico.<\/p>\n\n\n\n

Al conformar aceros inoxidables, materiales de alta resistencia o tiras recubiertas, la fricci\u00f3n aumenta y el desgaste adhesivo se vuelve predominante. En estas condiciones, la resistencia al agarrotamiento adquiere mayor importancia que la dureza m\u00e1xima.<\/p>\n\n\n\n

En condiciones de conformado con precalentamiento, tambi\u00e9n debe tenerse en cuenta la resistencia al agrietamiento t\u00e9rmico, aunque no sea el factor principal en la mayor\u00eda de las aplicaciones de conformado por rodillos.<\/p>\n\n\n\n

La maquinabilidad y la respuesta a los tratamientos superficiales afectan directamente la frecuencia de reafilado y el costo de las herramientas. Muchos troqueles de conformado por rodillos dependen de la nitruraci\u00f3n o el cromado duro para controlar el da\u00f1o superficial, y el material base debe permanecer estable durante estos procesos.<\/p>\n\n\n\n

Aceros para herramientas recomendados<\/h2>\n\n\n\n
\n

Acero para herramientas AISI D2 | 1.2379 | SKD11<\/h3>\n\n\n\n

El acero D2 se utiliza en aplicaciones donde el desgaste abrasivo limita la vida \u00fatil de la herramienta. Su alto contenido de carburo proporciona una gran resistencia a la degradaci\u00f3n superficial, lo que permite que el perfil del rodillo se mantenga estable durante largos ciclos de producci\u00f3n.<\/p>\n\n\n\n

Su rendimiento es \u00f3ptimo en procesos estables con carga constante. Cuando la alineaci\u00f3n est\u00e1 controlada y la variaci\u00f3n de la tensi\u00f3n es limitada, el D2 prolonga la vida \u00fatil al reducir el mantenimiento derivado del desgaste. Sin embargo, su menor tenacidad lo hace menos fiable en condiciones de tensi\u00f3n localizada o inestabilidad.<\/p>\n\n\n\n

\n

Acero para herramientas AISI O1 | 1.2510 | SKS3 y acero para herramientas AISI L6 | 1.2714 | SKT4<\/h3>\n\n\n\n

Las aleaciones O1 y L6 se seleccionan cuando la estabilidad del proceso es menor o cuando las condiciones de carga var\u00edan. En comparaci\u00f3n con las aleaciones con alto contenido de cromo, ofrecen una mayor resistencia al astillamiento bajo tensiones fluctuantes.<\/p>\n\n\n\n

Su resistencia al desgaste es menor, lo que aumenta la frecuencia de mantenimiento en entornos de alta fricci\u00f3n. En la pr\u00e1ctica, suelen combinarse con tratamientos superficiales como el cromado duro para reducir el desgaste adhesivo.<\/p>\n\n\n\n

Estos grados se suelen utilizar en producciones de tiradas medias o en configuraciones donde el estado y la alineaci\u00f3n de la banda no est\u00e1n totalmente controlados.<\/p>\n\n\n\n

\n

Acero para herramientas AISI M42 | 1.3247 | SKH59<\/h3>\n\n\n\n

Al conformar materiales de ultra alta resistencia, los aceros convencionales para herramientas de trabajo en fr\u00edo pueden fallar debido a la r\u00e1pida degradaci\u00f3n de la superficie y la concentraci\u00f3n de carga.<\/p>\n\n\n\n

El M42 mantiene su dureza y resistencia en estas condiciones y mejora su resistencia al desgaste adhesivo. Se utiliza cuando los grados est\u00e1ndar no logran mantener la vida \u00fatil de la herramienta bajo carga y fricci\u00f3n combinadas.<\/p>\n\n\n\n

La selecci\u00f3n debe basarse en el mecanismo que limita la vida \u00fatil de la herramienta en la producci\u00f3n.<\/p>\n\n\n\n

    \n
  • Si el fallo se produce como una p\u00e9rdida gradual del perfil, se debe priorizar la resistencia al desgaste, y el D2 suele ser eficaz.<\/li>\n\n\n\n
  • Si aparecen desconchones o inestabilidad antes de un desgaste significativo, los grados m\u00e1s resistentes, como el O1 o el L6, son m\u00e1s fiables.<\/li>\n\n\n\n
  • Si el desgaste por fricci\u00f3n o los da\u00f1os superficiales limitan la vida \u00fatil de la herramienta, los aceros A6 o los aceros de baja aleaci\u00f3n con tratamiento superficial son m\u00e1s adecuados.<\/li>\n\n\n\n
  • Si los materiales de alta resistencia provocan una r\u00e1pida degradaci\u00f3n, se hacen necesarios aceros de alta velocidad como el M42.<\/li>\n<\/ul>\n\n\n\n

    La elecci\u00f3n correcta viene determinada por el mecanismo de fallo dominante, no por la dureza m\u00e1xima.<\/p>\n\n\n\n
