Selecci\u00f3n de acero para herramientas para matrices de encabezado en fr\u00edo<\/h1>\n\n\n\n

El encabezado en fr\u00edo es un proceso de conformado masivo utilizado para producir componentes de gran volumen, como sujetadores, mediante deformaci\u00f3n pl\u00e1stica a temperatura ambiente. Las matrices est\u00e1n sometidas a cargas de impacto c\u00edclicas y tensiones de compresi\u00f3n de hasta aproximadamente 2413 MPa (350 ksi).<\/p>\n\n\n\n

Aunque se clasifica como un proceso en fr\u00edo, las temperaturas localizadas en la interfaz matriz-pieza pueden aumentar varios cientos de grados Celsius debido a la energ\u00eda de deformaci\u00f3n y la fricci\u00f3n. Esto afecta la dureza superficial y acelera el desgaste.<\/p>\n\n\n\n

En estas condiciones, la falla de la matriz est\u00e1 gobernada principalmente por desgaste abrasivo, agarrotamiento adhesivo y agrietamiento por fatiga. En aplicaciones de alta carga, una tenacidad insuficiente provoca desportillado de bordes o fractura fr\u00e1gil repentina.<\/p>\n\n\n\n

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

La selecci\u00f3n de acero para herramientas para matrices de encabezado en fr\u00edo est\u00e1 determinada por la interacci\u00f3n entre resistencia al desgaste, tenacidad y resistencia a la compresi\u00f3n.<\/p>\n\n\n\n

Se requiere alta dureza superficial para resistir abrasi\u00f3n, adhesi\u00f3n y deformaci\u00f3n pl\u00e1stica. En la mayor\u00eda de las aplicaciones, la dureza de trabajo var\u00eda de 56\u201362 HRC. Sin embargo, aumentar la dureza reduce la tenacidad, lo que incrementa el riesgo de agrietamiento bajo impacto c\u00edclico.<\/p>\n\n\n\n

Como resultado, las matrices de encabezado en fr\u00edo no se dise\u00f1an como componentes con dureza uniforme. En cambio, el rendimiento depende de un gradiente de dureza: una superficie dura y resistente al desgaste respaldada por un n\u00facleo m\u00e1s tenaz que absorbe la tensi\u00f3n de impacto.<\/p>\n\n\n\n

Este requisito se logra mediante dos enfoques:<\/p>\n\n\n\n

Los aceros de temple superficial desarrollan una superficie dura con un n\u00facleo relativamente tenaz durante el tratamiento t\u00e9rmico. Son adecuados para matrices macizas bajo alto impacto.<\/p>\n\n\n\n

Los aceros de temple profundo y alta aleaci\u00f3n proporcionan alta dureza uniforme y, por lo tanto, se utilizan como insertos, donde una carcasa exterior m\u00e1s tenaz soporta la carga mec\u00e1nica.<\/p>\n\n\n\n

Por lo tanto, la selecci\u00f3n no se basa solo en el material, sino que tambi\u00e9n depende de si la matriz est\u00e1 dise\u00f1ada como herramienta maciza o como inserto.<\/p>\n\n\n\n

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

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

El D2 se utiliza en aplicaciones donde el desgaste abrasivo es el mecanismo de falla dominante y la carga de impacto es moderada.<\/p>\n\n\n

Su alto contenido de carbono y cromo produce un gran volumen de carburos duros, lo que proporciona una fuerte resistencia al desgaste a 58\u201360 HRC. Sin embargo, su tenacidad relativamente baja lo hace inadecuado para matrices macizas bajo impacto severo.<\/p>\n\n\n

Por esta raz\u00f3n, el D2 se utiliza t\u00edpicamente como inserto, donde la estructura circundante de la matriz absorbe la carga.<\/p>\n\n\n

\n\n

S1 y S7 (aceros para herramientas resistentes al impacto)<\/h3>\n\n\n

S1 y S7 se seleccionan cuando la fractura inducida por impacto es el modo de falla dominante.<\/p>\n\n\n

El S7 se usa ampliamente debido a su comportamiento de temple al aire y tenacidad estable. Se utiliza t\u00edpicamente a 56\u201358 HRC para reducir el riesgo de agrietamiento inducido por impacto. En comparaci\u00f3n con aceros de mayor dureza, proporciona menor resistencia al desgaste pero una resistencia significativamente mayor a la fractura por fatiga.<\/p>\n\n\n

El S1 se prefiere en matrices con concentraci\u00f3n de tensiones, donde debe controlarse la iniciaci\u00f3n de grietas.<\/p>\n\n\n

Estos aceros son adecuados para matrices macizas que operan bajo condiciones de impacto severo, donde el desgaste no es el factor limitante principal.<\/p>\n\n\n

\n\n

Acero para herramientas AISI M2 | 1.3343 | SKH51<\/h3>\n\n\n

El M2 se utiliza en aplicaciones de alta carga que implican desgaste severo, alta tensi\u00f3n de contacto o materiales que endurecen por deformaci\u00f3n.<\/p>\n\n\n

Ofrece mayor resistencia a la compresi\u00f3n y resistencia al desgaste que el D2 y se utiliza t\u00edpicamente a 62\u201364 HRC. A diferencia de los aceros convencionales para trabajo en fr\u00edo, el M2 mantiene la dureza a temperaturas elevadas, lo que ayuda a prevenir el ablandamiento superficial y la deformaci\u00f3n pl\u00e1stica durante el conformado a alta velocidad.<\/p>\n\n\n

Debido al costo, el M2 se utiliza principalmente como inserto en zonas cr\u00edticas de desgaste.<\/p>\n\n\n

W1 y W2 (aceros para herramientas de temple en agua)<\/h3>\n\n\n

W1 y W2 son aceros de temple superficial utilizados para punzones y matrices macizas bajo alta carga de impacto.<\/p>\n\n\n

Pueden alcanzar una dureza superficial superior a 60 HRC mientras mantienen un n\u00facleo m\u00e1s tenaz, debido a su templabilidad limitada. Esta estructura permite que la matriz absorba el impacto sin agrietarse.<\/p>\n\n\n

Sin embargo, el temple en agua introduce un alto riesgo de distorsi\u00f3n y agrietamiento, lo que limita su uso a geometr\u00edas simples y secciones m\u00e1s peque\u00f1as.<\/p>\n\n<\/div>\n\n\n\n
