En la fabricaci\u00f3n moderna, la extrusi\u00f3n en fr\u00edo es un proceso fundamental para la producci\u00f3n en masa de componentes de precisi\u00f3n en los sectores automotriz, aeroespacial y de maquinaria industrial. La vida \u00fatil de las matrices de extrusi\u00f3n en fr\u00edo suele determinar directamente la rentabilidad de una empresa. Seleccionar el acero para herramientas m\u00e1s adecuado para punzones y matrices representa una decisi\u00f3n estrat\u00e9gica crucial para la rentabilidad.<\/p>\n\n\n\n

La extrusi\u00f3n en fr\u00edo, tambi\u00e9n conocida como forjado en fr\u00edo o extrusi\u00f3n por impacto en fr\u00edo, se realiza normalmente a temperaturas inferiores a 200 \u00b0C (390 \u00b0F). El proceso general consiste en colocar una pieza met\u00e1lica en bruto dentro de una matriz fija, donde un punz\u00f3n de alta velocidad fuerza al metal a fluir pl\u00e1sticamente, logrando finalmente la forma deseada.<\/p>\n\n\n\n

Este proceso impone requisitos extremadamente exigentes a los materiales de las herramientas y matrices. El acero para matrices debe soportar esfuerzos de compresi\u00f3n extremos, un desgaste abrasivo severo y cargas de fatiga din\u00e1mica en un plazo de tiempo extremadamente corto.<\/p>\n\n\n\n

El acero de uso general ya no cumple con los requisitos anteriores; se debe utilizar acero para herramientas y matrices tratado t\u00e9rmicamente. La raz\u00f3n fundamental para seleccionar acero para herramientas y matrices es lograr un equilibrio entre alta dureza y alta tenacidad.<\/p>\n\n\n\n

Las exigencias cr\u00edticas de las herramientas de extrusi\u00f3n en fr\u00edo<\/h2>\n\n\n\n

Las matrices de extrusi\u00f3n en fr\u00edo se enfrentan a tres desaf\u00edos fundamentales.<\/p>\n\n\n\n

1. Presi\u00f3n extrema y esfuerzo de compresi\u00f3n<\/h3>\n\n\n\n

La extrusi\u00f3n en fr\u00edo funciona induciendo el flujo pl\u00e1stico en el metal a temperatura ambiente. Para forzar el metal a trav\u00e9s de una cavidad espec\u00edfica de la matriz, esta debe soportar una enorme fuerza de reacci\u00f3n. Los punzones y matrices de calidad deben soportar presiones m\u00e1ximas de hasta 2415 MPa (350 ksi). Bajo tal presi\u00f3n, el acero com\u00fan se deforma como la arcilla. La resistencia a la compresi\u00f3n es la consideraci\u00f3n principal para el acero de herramientas y matrices, ya que garantiza que la matriz no sufra deformaci\u00f3n pl\u00e1stica ni colapse bajo presi\u00f3n extrema.<\/p>\n\n\n\n

2. Resistencia al desgaste<\/h3>\n\n\n\n

Bajo alta presi\u00f3n, las superficies de la pieza met\u00e1lica en bruto y del troquel experimentan un intenso deslizamiento relativo, lo que provoca desgaste abrasivo y adhesivo. La resistencia al desgaste determina directamente la vida \u00fatil del troquel y la precisi\u00f3n dimensional del producto final. Por ello, los aceros para herramientas con alto contenido de carbono y cromo, como la serie D, se utilizan ampliamente en este sector.<\/p>\n\n\n\n

3. Resistencia y fatiga<\/h3>\n\n\n\n

Para soportar altas presiones y desgaste, es necesario aumentar la dureza; sin embargo, una dureza excesiva vuelve el acero quebradizo. La extrusi\u00f3n en fr\u00edo es un proceso c\u00edclico din\u00e1mico. En particular, para punzones delgados con una elevada relaci\u00f3n longitud-di\u00e1metro, una tenacidad insuficiente ante impactos repetidos los hace altamente susceptibles a la fractura por fatiga o al astillamiento prematuro.<\/p>\n\n\n\n

Principales categor\u00edas de aceros para herramientas utilizados en la extrusi\u00f3n en fr\u00edo.<\/h2>\n\n\n\n

En resumen, los requisitos para la selecci\u00f3n de materiales en los procesos de extrusi\u00f3n en fr\u00edo son alta dureza, alta resistencia al desgaste y suficiente tenacidad.<\/p>\n\n\n\n

1. Aceros de alta velocidad (HSS)<\/h3>\n\n\n\n

El acero de alta velocidad no solo se utiliza para herramientas de corte; tambi\u00e9n destaca en matrices de extrusi\u00f3n en fr\u00edo, en particular en punzones e insertos de matrices.<\/p>\n\n\n\n

El acero r\u00e1pido (HSS) presenta una dureza excepcional en caliente, manteniendo una alta dureza hasta los 600 \u00b0C. Durante la extrusi\u00f3n a alta velocidad, donde se producen altas temperaturas instant\u00e1neas, los bordes de trabajo de las matrices de HSS no se ablandan.<\/p>\n\n\n\n

Ejemplo: El acero M2 es la opci\u00f3n est\u00e1ndar para punzones de extrusi\u00f3n en fr\u00edo. Tiene una resistencia al desgaste de 7 y una tenacidad de 3.<\/p>\n\n\n\n

El acero M4 es adecuado para aplicaciones de extrusi\u00f3n en fr\u00edo que requieren una mayor resistencia al desgaste. Tiene una clasificaci\u00f3n de resistencia al desgaste de 9 y una clasificaci\u00f3n de tenacidad de 3.<\/p>\n\n\n\n

T15 steel is suitable for cold-extrusion applications that require higher wear resistance. It has a wear resistance rating of 9 and a toughness rating of 1. T15 offers top-tier wear resistance, but this comes at the expense of toughness. It is suitable for precision dies operating under extremely stable conditions with minimal lateral forces but experiencing severe wear.<\/p>\n\n\n\n

2. Aceros para herramientas de trabajo en fr\u00edo (series D y A)<\/h3>\n\n\n\n

Para los compradores e ingenieros en el campo del conformado en fr\u00edo, las opciones m\u00e1s comunes suelen girar en torno a tres materiales: AISI D2 (1,2379), AISI A2 (1,2363) y AISI O1 (1,2510).<\/p>\n\n\n\n

El acero AISI D2 (1.2379) es un acero para herramientas de trabajo en fr\u00edo con alto contenido de carbono y cromo, que se distingue por su excepcional resistencia al desgaste y al reblandecimiento. Obtiene una calificaci\u00f3n de 8 en resistencia al desgaste y 2 en tenacidad. El D2 es la opci\u00f3n \u00f3ptima para matrices de producci\u00f3n de alto volumen y larga duraci\u00f3n. Se utiliza ampliamente en matrices de extrusi\u00f3n en fr\u00edo, matrices de punzonado y diversas cuchillas de corte.<\/p>\n\n\n\n

Cuando los troqueles D2 presentan astillamiento o fractura durante su uso, el acero AISI A2 suele ser la alternativa \u00f3ptima. Obtiene una puntuaci\u00f3n de 6 en resistencia al desgaste y 5 en tenacidad, ofreciendo una combinaci\u00f3n equilibrada de estas propiedades. El A2 es un acero vers\u00e1til para conformado en fr\u00edo que conserva una buena resistencia al desgaste y una resistencia al impacto superior a la del D2, lo que lo hace adecuado para aplicaciones ligeramente m\u00e1s exigentes.<\/p>\n\n\n\n

El acero para herramientas AISI O1, de bajo costo y endurecible al aceite, sigue disponible en el mercado. Obtiene una calificaci\u00f3n de 4 en resistencia al desgaste y 8 en tenacidad. Si bien su resistencia al desgaste es menor que la del D2, su tenacidad es excepcional. Si sus matrices fallan principalmente por fractura en lugar de desgaste, o si necesita un material para herramientas de bajo costo, el O1 ofrece una opci\u00f3n muy rentable.<\/p>\n\n\n\n

3. Aceros para herramientas de trabajo en caliente (serie H)<\/h3>\n\n\n\n

En aplicaciones de extrusi\u00f3n en fr\u00edo, la dureza es crucial, pero no el \u00fanico factor. Cuando las matrices se enfrentan a entornos de tensi\u00f3n extremadamente complejos o extruyen aceros de alta resistencia, una dureza excesivamente alta puede provocar una fractura fr\u00e1gil instant\u00e1nea. En tales casos, se requiere una estrategia de selecci\u00f3n de materiales diferente. Para lograr la resistencia a la fractura necesaria, aunque se sacrifique algo de resistencia a la compresi\u00f3n, recomendamos encarecidamente el uso de H11 o H13. Estos aceros absorben la energ\u00eda del impacto como resortes, en lugar de romperse como el vidrio. Los aceros para herramientas de trabajo en caliente de carbono medio, como el H11\/H13, alcanzan una tenacidad de 9.<\/p>\n\n\n\n

El H11\/H13 tambi\u00e9n cumple otra funci\u00f3n. Para evitar la rotura de costosos insertos de carburo o acero para herramientas de alta dureza dentro de la matriz, se pueden colocar uno o m\u00e1s anillos de contracci\u00f3n de H11 o H13 (1.2344) alrededor del exterior de los insertos. Esta configuraci\u00f3n se denomina matriz compuesta pretensada. Aprovechando la expansi\u00f3n y contracci\u00f3n t\u00e9rmica, los anillos de H11\/H13 se calientan y se colocan sobre el inserto. Al enfriarse, esto crea una importante pretensi\u00f3n interna. Esta fuerza contrarresta la tensi\u00f3n de tracci\u00f3n externa durante la extrusi\u00f3n en fr\u00edo, evitando el agrietamiento del inserto. Para esta aplicaci\u00f3n, el H11\/H13 no requiere una dureza extremadamente alta; un tratamiento t\u00e9rmico a 46-48 HRC suele ser suficiente. Este rango de dureza garantiza una excelente tenacidad y estabilidad estructural.<\/p>\n\n\n\n

Acero para herramientas H11 | 1.2343 | SKD6<\/h4>\n\n\n\n

El acero al cromo para trabajo en caliente H11 es un material complementario fundamental para matrices de extrusi\u00f3n en fr\u00edo, ya que su alta tenacidad previene eficazmente la fractura fr\u00e1gil repentina de la matriz. Este grado de acero se utiliza com\u00fanmente para fabricar anillos de contracci\u00f3n y marcos de matriz con una dureza de 46 a 52 HRC. Su alta ductilidad le permite soportar presiones de ruptura inmensas. En componentes sometidos a altas tensiones que requieren una resistencia superior al impacto, el H11 garantiza la integridad estructural general de las herramientas, superando la fragilidad inherente a los materiales de alta dureza.<\/p>\n\n\n\n

 Tratamiento t\u00e9rmico y mejora de la superficie<\/h2>\n\n\n\n

Our customers have encountered this situation: dies pass hardness tests during factory inspection, yet suddenly crack shortly after machine operation begins. This is most likely due to retained austenite. During quenching, if the austenite in the steel is not fully transformed into martensite, the remaining portion is called retained austenite. This phase is unstable and spontaneously transforms into brittle martensite during die service, especially under high stress or high-speed impact. This transformation involves volume expansion, generating immense internal stresses within the die that ultimately lead to fatigue fracture.<\/p>\n\n\n\n

Para aplicaciones de alta exigencia, como las matrices de extrusi\u00f3n en fr\u00edo, nunca se deben realizar solo uno o dos ciclos de revenido para ahorrar costes. La pr\u00e1ctica est\u00e1ndar en la industria es el triple revenido. Esto garantiza que la mayor parte de la austenita retenida se transforme correctamente, eliminando la inestabilidad interna de la matriz.<\/p>\n\n\n\n

Una vez que el material base alcanza la resistencia y tenacidad suficientes, debemos aplicar una capa protectora al troquel para que resista el desgaste extremo. La nitruraci\u00f3n es el m\u00e9todo de endurecimiento superficial m\u00e1s com\u00fan. Mediante este proceso, se forma una capa de compuesto extremadamente duro en la superficie del troquel, lo que mejora a\u00fan m\u00e1s su resistencia al desgaste.<\/p>\n\n\n\n
