The Best Tool Steel for Coining Dies Depends on the Failure Mode<\/h1>\n\n\n\n

Los troqueles de acu\u00f1aci\u00f3n de precisi\u00f3n trabajan bajo una carga de compresi\u00f3n extremadamente alta. El material de la pieza de trabajo queda totalmente confinado dentro de la cavidad del troquel, por lo que este debe forzar el flujo del material hacia detalles finos como bordes afilados, peque\u00f1as cavidades, texturas y patrones decorativos.<\/p>\n\n\n\n

Para este tipo de herramientas, la selecci\u00f3n del material no puede basarse \u00fanicamente en la dureza o la resistencia general. El acero para herramientas seleccionado debe ser compatible con el principal riesgo de fallo: desgaste, deformaci\u00f3n pl\u00e1stica, agrietamiento, astillamiento o distorsi\u00f3n por tratamiento t\u00e9rmico.<\/p>\n\n\n\n

Un acero con excelente resistencia al desgaste puede agrietarse si la matriz tiene detalles afilados o un soporte deficiente. Un acero m\u00e1s resistente puede soportar mejor los impactos, pero puede desgastarse o deformarse demasiado r\u00e1pido en series de producci\u00f3n largas. La elecci\u00f3n correcta depende del modo de fallo que determine la vida \u00fatil de la herramienta.<\/p>\n\n\n\n

Need Help Selecting Tool Steel for Your Coining Die?<\/a><\/div>\n<\/div>\n\n\n\n

\u00bfPor qu\u00e9 fallan los troqueles de acu\u00f1aci\u00f3n de precisi\u00f3n?<\/h2>\n\n\n\n

Las fallas en los troqueles de acu\u00f1aci\u00f3n de precisi\u00f3n generalmente se deben a cuatro causas principales: desgaste superficial, deformaci\u00f3n pl\u00e1stica, agrietamiento e inestabilidad dimensional. Cada modo de falla indica una direcci\u00f3n diferente para la selecci\u00f3n del material.<\/p>\n\n\n\n

1. Desgaste y p\u00e9rdida de detalles<\/h3>\n\n\n\n

El desgaste se produce cuando el contacto repetido a alta presi\u00f3n da\u00f1a gradualmente la superficie de la matriz. En el acu\u00f1ado de precisi\u00f3n, esto conlleva la p\u00e9rdida de detalles finos, bordes redondeados, una reproducci\u00f3n deficiente de la superficie y una menor precisi\u00f3n dimensional.<\/p>\n\n\n\n

Si el desgaste es el principal modo de fallo, el acero para matrices necesita mayor dureza, mayor soporte de carburo y mejor resistencia a la abrasi\u00f3n. Los aceros para herramientas D2, D3, D4, PM o los insertos de carburo suelen ser m\u00e1s adecuados que los aceros tenaces de baja aleaci\u00f3n.<\/p>\n\n\n\n

2. Deformaci\u00f3n pl\u00e1stica y hundimiento<\/h3>\n\n\n\n

La deformaci\u00f3n pl\u00e1stica se produce cuando la superficie del molde no puede resistir la carga de compresi\u00f3n aplicada. La superficie comienza a hundirse, a agrandarse o a perder su geometr\u00eda original.<\/p>\n\n\n\n

Este problema es frecuente cuando la presi\u00f3n es alta, la superficie de contacto es grande o el material del molde no es lo suficientemente duro despu\u00e9s del tratamiento t\u00e9rmico. En este caso, conviene optar por aceros con mayor dureza y resistencia a la compresi\u00f3n, como los grados D2, D3 o grados PM adecuados.<\/p>\n\n\n\n

3. Agrietamiento, astillamiento y divisi\u00f3n<\/h3>\n\n\n\n

El agrietamiento suele deberse a la concentraci\u00f3n de tensiones combinada con una tenacidad insuficiente. Las esquinas afiladas, las hendiduras profundas, las nervaduras delgadas y las secciones con soporte deficiente pueden generar picos de tensi\u00f3n localizados. Bajo cargas repetidas, las grietas pueden iniciarse en estas zonas y progresar hasta el astillamiento o la fractura completa.<\/p>\n\n\n\n

Si el agrietamiento es el principal modo de fallo, los aceros de alta resistencia al desgaste, como el D2 o el D3, podr\u00edan no ser la opci\u00f3n m\u00e1s segura. Los aceros m\u00e1s resistentes, como los de la serie S, L6, H11, H12 o H13, podr\u00edan ofrecer una vida \u00fatil m\u00e1s prolongada, aunque su resistencia al desgaste sea menor.<\/p>\n\n\n\n

4. Distorsi\u00f3n por tratamiento t\u00e9rmico<\/h3>\n\n\n\n

Los troqueles de acu\u00f1aci\u00f3n de precisi\u00f3n suelen requerir un control dimensional estricto. Si el troquel cambia de tama\u00f1o o forma durante el endurecimiento, incluso una peque\u00f1a deformaci\u00f3n puede inutilizarlo.<\/p>\n\n\n\n

Para matrices de mayor tama\u00f1o, formas complejas o herramientas de alta precisi\u00f3n, a menudo se prefieren los aceros de endurecimiento al aire, como el A2 o el A6, porque proporcionan una mayor estabilidad dimensional que los aceros de endurecimiento al agua o al aceite.<\/p>\n\n\n\n

Selecci\u00f3n de aceros para herramientas de troqueles de acu\u00f1aci\u00f3n seg\u00fan la condici\u00f3n de producci\u00f3n.<\/h2>\n\n\n\n

El material adecuado depende del volumen de producci\u00f3n, el material de la pieza, la geometr\u00eda del troquel y los requisitos de fabricaci\u00f3n. Estos factores determinan si se debe priorizar la resistencia al desgaste, la tenacidad, la resistencia a la compresi\u00f3n o la estabilidad dimensional.<\/p>\n\n\n\n

Cu\u00e1ndo NO utilizar ciertos aceros para herramientas<\/h2>\n\n\n\n

1. No utilice aceros de alta resistencia al desgaste cuando el agrietamiento controla la falla.<\/h3>\n\n\n\n

Los materiales D2, D3 y D4 son excelentes opciones cuando la resistencia al desgaste y la resistencia a la compresi\u00f3n son los requisitos principales. Sin embargo, no son ideales cuando el troquel tiene cavidades profundas, detalles afilados, secciones delgadas sin soporte o est\u00e1 sometido a cargas de impacto repetidas.<\/p>\n\n\n\n

Su alto contenido de carburos mejora la resistencia al desgaste, pero reduce la tenacidad. En matrices propensas a agrietarse, estos carburos pueden actuar como puntos de inicio de grietas. Si la matriz se astilla, se raja o se fractura repetidamente, conviene optar por aceros m\u00e1s resistentes, como los de la serie S, L6, H11, H12 o H13.<\/p>\n\n\n\n

2. No utilice aceros de baja aleaci\u00f3n resistentes cuando el desgaste o la deformaci\u00f3n pl\u00e1stica controlan la falla.<\/h3>\n\n\n\n

Los aceros resistentes son \u00fatiles cuando el principal riesgo es el agrietamiento, pero es posible que no ofrezcan suficiente resistencia al desgaste o a la compresi\u00f3n para series de producci\u00f3n largas.<\/p>\n\n\n\n

Si la matriz pierde detalle, se desgasta r\u00e1pidamente o se hunde bajo presi\u00f3n, la tenacidad por s\u00ed sola no resolver\u00e1 el problema. En este caso, son m\u00e1s adecuados los aceros de mayor dureza y con mayor contenido de carburo, como los aceros para herramientas D2, D3, D4 o PM, o las plaquitas de carburo.<\/p>\n\n\n\n

3. No conf\u00ede en un solo tipo de acero cuando se requiera tanto resistencia al desgaste como tenacidad.<\/h3>\n\n\n\n

Algunas aplicaciones de acu\u00f1ado de precisi\u00f3n requieren tanto alta resistencia al desgaste como alta resistencia a la fractura. Un solo tipo de acero puede no satisfacer ambos requisitos.<\/p>\n\n\n\n

En estos casos, una soluci\u00f3n estructural suele ser la mejor opci\u00f3n. Un inserto resistente al desgaste, fabricado en acero D2, PM o carburo, puede apoyarse sobre un soporte m\u00e1s robusto de acero H11, H13 o L6. Esto permite que la superficie de trabajo resista el desgaste, mientras que la estructura de soporte reduce el riesgo de fractura.<\/p>\n\n\n\n

Tambi\u00e9n se pueden utilizar tratamientos o recubrimientos superficiales cuando un acero resistente necesita una mayor resistencia al desgaste superficial, pero el acero base debe seguir teniendo la resistencia y estabilidad suficientes para la aplicaci\u00f3n.<\/p>\n\n\n\n

L\u00f3gica de selecci\u00f3n pr\u00e1ctica<\/h2>\n\n\n\n

Si la matriz falla por desgaste o p\u00e9rdida de detalle, elija un acero con mayor dureza, mayor soporte de carburo y mejor resistencia a la abrasi\u00f3n. Los aceros para herramientas D2, D3, D4, PM o los insertos de carburo suelen ser adecuados.<\/p>\n\n\n\n

Si el troquel falla debido a deformaci\u00f3n pl\u00e1stica o hundimiento, el material carece de la resistencia a la compresi\u00f3n suficiente para soportar la presi\u00f3n aplicada. La soluci\u00f3n consiste en aumentar la dureza o utilizar aceros como el D2, el D3 o grados PM adecuados.<\/p>\n\n\n\n

Si la matriz falla por agrietamiento, astillamiento o rotura, el material es demasiado fr\u00e1gil para la geometr\u00eda o las condiciones de carga. Se deben considerar aceros m\u00e1s resistentes como el A2, los aceros de la serie S, el L6, el H11, el H12 o el H13.<\/p>\n\n\n\n

Si la matriz no puede mantener la precisi\u00f3n dimensional despu\u00e9s del tratamiento t\u00e9rmico, la estabilidad dimensional se convierte en la prioridad. Los grados A2 o A6 pueden ser mejores que los grados de endurecimiento por agua o aceite.<\/p>\n\n\n\n

Si el troquel requiere alta resistencia al desgaste y alta tenacidad, no se base \u00fanicamente en la selecci\u00f3n del grado del material. Utilice un dise\u00f1o de inserto adecuado, un soporte apropiado y un tratamiento t\u00e9rmico apropiado para controlar tanto el desgaste superficial como el riesgo de fractura.<\/p>\n\n\n\n

\u00bfA\u00fan no est\u00e1 seguro de qu\u00e9 acero para herramientas es el adecuado para su matriz de acu\u00f1aci\u00f3n? \u00a1Cont\u00e1ctenos ahora!<\/a><\/div>\n<\/div>\n\n\n\n

Preguntas frecuentes<\/h2>\n\n\n\n
\u00bfCu\u00e1l es el factor m\u00e1s importante a la hora de seleccionar acero para herramientas destinado a matrices de acu\u00f1aci\u00f3n de precisi\u00f3n?<\/strong>

El factor clave no es solo la dureza, sino el modo de fallo predominante. El acero para herramientas debe seleccionarse en funci\u00f3n de si la matriz falla por desgaste, deformaci\u00f3n, agrietamiento o distorsi\u00f3n.<\/p> <\/div>

\u00bfQu\u00e9 acero para herramientas es el mejor para series de producci\u00f3n largas?<\/strong>

Para ciclos de funcionamiento prolongados con alto desgaste y presi\u00f3n, generalmente se prefieren los tipos D2, D3 y D4 debido a su alto contenido de carburo y su fuerte resistencia al desgaste.<\/p> <\/div>

\u00bfPor qu\u00e9 se agrietan los troqueles de acu\u00f1aci\u00f3n de precisi\u00f3n incluso cuando se utilizan aceros de alta resistencia?<\/strong>

El agrietamiento suele deberse a la concentraci\u00f3n de tensiones y a una tenacidad insuficiente, no a la falta de resistencia. Los aceros de alta resistencia al desgaste, como el D2 y el D3, son fr\u00e1giles y pueden fallar en matrices con detalles afilados o soportes d\u00e9biles.<\/p> <\/div>

\u00bfCu\u00e1ndo debo elegir acero para herramientas A2?<\/strong>

El acero A2 es adecuado cuando la estabilidad dimensional durante el tratamiento t\u00e9rmico es fundamental, especialmente para series de producci\u00f3n medianas y matrices de precisi\u00f3n que no toleran la deformaci\u00f3n.<\/p> <\/div>

\u00bfPor qu\u00e9 mi dado pierde detalle o se redondea con el tiempo?<\/strong>

Esto se debe al desgaste superficial. La soluci\u00f3n consiste en utilizar aceros con mayor dureza y contenido de carburo, como los aceros para herramientas D2, D3 o PM.<\/p> <\/div>

\u00bfQu\u00e9 causa la deformaci\u00f3n pl\u00e1stica (hundimiento) en los troqueles de acu\u00f1aci\u00f3n?<\/strong>

La deformaci\u00f3n pl\u00e1stica se produce cuando el material carece de suficiente resistencia a la compresi\u00f3n. Es necesario aumentar la dureza o seleccionar aceros de mayor resistencia, como los de grados D2 o PM.<\/p> <\/div>

\u00bfQu\u00e9 aceros son mejores para matrices con bordes afilados o cavidades profundas?<\/strong>

Para zonas de alta concentraci\u00f3n de tensiones, utilice aceros m\u00e1s resistentes, como los de la serie S, L6 o H11\/H13, para reducir el riesgo de agrietamiento y astillamiento.<\/p> <\/div>

\u00bfPuede un solo tipo de acero cumplir con los requisitos de resistencia al desgaste y tenacidad a la vez?<\/strong>

En muchos casos, no. Cuando se requieren ambos, es mejor un enfoque de dise\u00f1o combinado, como por ejemplo:
Inserto resistente al desgaste (D2, acero PM, carburo)
Material de soporte resistente (H11, H13, L6)<\/p> <\/div>

\u00bfCu\u00e1ndo debo evitar usar D2 o D3?<\/strong>

El troquel tiene secciones delgadas o caracter\u00edsticas afiladas.
El modo de fallo es agrietamiento o astillamiento.
La aplicaci\u00f3n implica carga de choque<\/p> <\/div>

\u00bfCu\u00e1ndo debo evitar el uso de aceros resistentes de baja aleaci\u00f3n como el O1 o el W1?<\/strong>

El volumen de producci\u00f3n es alto.
El desgaste o la deformaci\u00f3n es el problema principal.
Carecen de suficiente resistencia al desgaste y a la compresi\u00f3n.<\/p> <\/div>

\u00bfC\u00f3mo influye el material de la pieza de trabajo en la selecci\u00f3n del acero para herramientas?<\/strong>

Metales blandos \u2192 O1, W1 son suficientes
Acero bajo en carbono \u2192 O1, A2, D2 dependiendo del volumen
Acero inoxidable o aleaciones de alta resistencia \u2192 Series S, series H para mayor tenacidad<\/p> <\/div>

\u00bfPor qu\u00e9 es importante la deformaci\u00f3n causada por el tratamiento t\u00e9rmico en los troqueles de acu\u00f1aci\u00f3n?<\/strong>

Incluso peque\u00f1os cambios dimensionales pueden hacer que los troqueles de precisi\u00f3n queden inservibles.
Para herramientas que requieren tolerancias estrictas, se prefieren los aceros de endurecimiento al aire (A2, A6) por su mayor estabilidad.<\/p> <\/div>

\u00bfCu\u00e1l es la mejor soluci\u00f3n para una demanda de producci\u00f3n muy alta?<\/strong>

Utilice aceros para herramientas de metalurgia de polvos o insertos de carburo, a menudo combinados con un sistema de soporte estructural para mayor durabilidad.<\/p> <\/div>

\u00bfLa dureza es siempre la prioridad a la hora de seleccionar un troquel para acu\u00f1ar monedas?<\/strong>

No. La dureza mejora la resistencia al desgaste, pero una dureza excesiva reduce la tenacidad.
La selecci\u00f3n debe equilibrar la resistencia al desgaste, la tenacidad y la resistencia a la compresi\u00f3n.<\/p> <\/div>

\u00bfCu\u00e1l es el m\u00e9todo pr\u00e1ctico para seleccionar los troqueles de acu\u00f1aci\u00f3n?<\/strong>

Desgaste \u2192 aumenta la dureza y el contenido de carburo.
