Selecci\u00f3n de aceros para herramientas para el conformado en fr\u00edo de tuercas hexagonales<\/h1>\n\n\n\n

El conformado en fr\u00edo de tuercas hexagonales es un proceso de varias etapas que se realiza bajo altas cargas de compresi\u00f3n e impactos repetidos, generalmente por debajo de los 200 \u00b0C. La falla de la herramienta no se debe al ablandamiento t\u00e9rmico, sino a la sobrecarga mec\u00e1nica y al da\u00f1o superficial.<\/p>\n\n\n\n

En la pr\u00e1ctica, las herramientas fallan principalmente debido al desgaste abrasivo, al desgaste adhesivo (agarrotamiento) y a la deformaci\u00f3n pl\u00e1stica bajo una tensi\u00f3n de contacto excesiva. Los modos de falla secundarios incluyen el astillamiento de los bordes y el agrietamiento por fatiga bajo carga c\u00edclica.<\/p>\n\n\n\n

Factores de selecci\u00f3n<\/h2>\n\n\n\n

La selecci\u00f3n del acero para herramientas en la conformaci\u00f3n de tuercas hexagonales es fundamentalmente un equilibrio entre la resistencia al desgaste y la tenacidad bajo altas tensiones de compresi\u00f3n.<\/p>\n\n\n\n

Una alta dureza mejora la resistencia al desgaste y la deformaci\u00f3n, lo cual es fundamental para mantener la geometr\u00eda de la matriz durante largos ciclos de producci\u00f3n. Sin embargo, un aumento en la dureza y el contenido de carburo reduce la tenacidad, incrementando el riesgo de astillamiento de los bordes o fractura fr\u00e1gil ante impactos repetidos.<\/p>\n\n\n\n

Debido a que las temperaturas de conformado son relativamente bajas, las propiedades t\u00e9rmicas como la dureza en caliente y la resistencia al agrietamiento por calor no son determinantes. La selecci\u00f3n del material debe centrarse en controlar el desgaste, mantener la estabilidad dimensional y prevenir la fractura bajo cargas c\u00edclicas.<\/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 material D2 se utiliza en aplicaciones donde el desgaste abrasivo y la estabilidad dimensional son los requisitos principales, y la carga de impacto es limitada.<\/p>\n\n\n\n

Con una dureza de trabajo de 58\u201360 HRC, el acero D2 ofrece una gran resistencia al desgaste superficial, manteniendo la precisi\u00f3n durante el tratamiento t\u00e9rmico. Sin embargo, su menor tenacidad lo hace menos adecuado para condiciones que impliquen impactos repetidos o cargas inestables.<\/p>\n\n\n\n

El material D2 es el m\u00e1s adecuado para matrices de precisi\u00f3n donde la resistencia al desgaste es fundamental y las condiciones de carga est\u00e1n bien controladas.<\/p>\n\n\n\n

\n

Acero de alta velocidad M4 (HSS)<\/h3>\n\n\n\n

El acero M4 se utiliza cuando el desgaste es el principal mecanismo de fallo y el volumen de producci\u00f3n es elevado. Su rendimiento es \u00f3ptimo en condiciones de carga estables, donde el astillamiento de los bordes no es el factor limitante.<\/p>\n\n\n\n

Rendimiento: En producci\u00f3n, las herramientas M4 pueden superar el mill\u00f3n de piezas cuando el desgaste controla la vida \u00fatil de la herramienta.
Mejora: Con un tratamiento t\u00e9rmico optimizado o un endurecimiento superficial a 63\u201365 HRC, la vida \u00fatil puede alcanzar aproximadamente 2,4 millones de piezas.<\/p>\n\n\n\n

El M4 es la opci\u00f3n preferida para la producci\u00f3n de volumen ultra alto, donde la m\u00e1xima resistencia al desgaste determina directamente la vida \u00fatil de la herramienta.<\/p>\n<\/div>\n\n\n\n

\n

Acero r\u00e1pido de tungsteno T1<\/h3>\n\n\n\n

Se selecciona el acero T1 cuando se presentan tanto desgaste como impacto, pero ninguno de ellos es extremo. En comparaci\u00f3n con los aceros r\u00e1pidos de aleaci\u00f3n superior, ofrece una respuesta m\u00e1s equilibrada bajo condiciones de carga mixtas.<\/p>\n\n\n\n

Con un tratamiento t\u00e9rmico est\u00e1ndar (temple en aceite a 1270 \u00b0C y doble revenido a 595 \u00b0C), el T1 suele producir alrededor de 350.000 piezas.<\/p>\n\n\n\n

El material T1 es adecuado para la producci\u00f3n de volumen medio a alto, donde se requiere una mayor resistencia para reducir el riesgo de astillamiento.<\/p>\n<\/div>\n\n\n\n

\n

Acero para herramientas al carbono (varilla de perforaci\u00f3n tipo W)<\/h3>\n\n\n\n

Para componentes no cr\u00edticos, como pasadores gu\u00eda o porta-matrices, donde el desgaste directo y el impacto son m\u00ednimos, el acero para herramientas al carbono ofrece una soluci\u00f3n rentable.<\/p>\n\n\n\n

Con una dureza de 58-60 HRC, ofrece suficiente resistencia a la compresi\u00f3n y rigidez sin el coste de los aceros de alta aleaci\u00f3n.<\/p>\n<\/div>\n\n\n\n
