En comparaci\u00f3n con las m\u00e1quinas de plegado y corte, la tolerancia de la m\u00e1quina perfiladora ser\u00e1 algo mayor. Sin embargo, dada su velocidad, los usuarios finales tambi\u00e9n la preferir\u00e1n.<\/p>\n

<\/p>\n

Tolerancia de la secci\u00f3n transversal<\/strong><\/h2>\n

El cliente, el dise\u00f1ador del producto y el dise\u00f1ador del rodillo deben acordar la interpretaci\u00f3n de las dimensiones y tolerancias especificadas en los dibujos antes de comenzar el dise\u00f1o del rodillo. <\/span>Las tolerancias del producto afectar\u00e1n el dise\u00f1o del rodillo, la cantidad de soportes y, por lo tanto, los costos de herramientas. <\/span>\u00a0Como regla general, cuanto m\u00e1s estrictas sean las tolerancias del producto, mayor ser\u00e1 el n\u00famero de soportes de perfilado. <\/span>La infinita variedad de secciones transversales y combinaciones de tolerancias hacen imposible poner un valor num\u00e9rico exacto al mayor n\u00famero de pasadas requeridas, pero los dise\u00f1adores de rodillos experimentados tienen una idea de cu\u00e1ntos soportes adicionales se necesitan para lograr las tolerancias requeridas.<\/span><\/p>\n

Desviaci\u00f3n de las tolerancias de rectitud y planitud<\/strong><\/h2>\n

La naturaleza del perfilado provocar\u00e1 combas, curvaturas, torceduras, arcos transversales, efectos de espiga, ondulaciones en los bordes o en el centro, as\u00ed como imperfecciones en el material, el equipo y la configuraci\u00f3n. <\/span>Las herramientas tienen una gran\u00a0<\/span>influencia en las tensiones residuales, que crean desviaciones de la rectitud y planitud. <\/span>Un buen dise\u00f1o de m\u00e1quina perfiladora los elimina o minimiza, mientras que\u00a0<\/span>El mal dise\u00f1o crea o exagera estos problemas.<\/span><\/p>\n

Tolerancia de la ubicaci\u00f3n de los orificios y las muescas de la m\u00e1quina formadora de rollos\u00a0<\/strong><\/h2>\n

El dise\u00f1ador de la m\u00e1quina perfiladora debe dictar la secuencia de operaciones si la secci\u00f3n transversal especifica los orificios, muescas, relieves u otros cambios en la superficie de la tira. <\/span>Durante el proceso de perfilado, ciertas partes del producto est\u00e1n bajo tensi\u00f3n, mientras que otras se comprimen. El dise\u00f1o de la m\u00e1quina perfiladora debe influir en...<\/span>La diferencia entre la longitud total de la pieza antes y despu\u00e9s del conformado.\u00a0<\/span>En algunos casos, el dise\u00f1ador puede proceder a perforar previamente el producto, utilizando las dimensiones finales o estimadas. <\/span>Con base en las mediciones de la ubicaci\u00f3n de los orificios antes y despu\u00e9s del perfilado, se puede ajustar el patr\u00f3n de prepunzonado. En ocasiones, para establecer las dimensiones finales del prepunzonado, el dise\u00f1ador debe repetir algunos pasos.<\/span>\u00a0<\/span>Sin embargo, es importante realizar la prueba con la misma presi\u00f3n de rodillo. <\/span>Una presi\u00f3n excesiva puede adelgazar el material y alargar el producto, arrojando as\u00ed resultados de prueba falsos en las ubicaciones de los orificios.<\/span><\/p>\n

En comparaci\u00f3n con la longitud de la banda antes del conformado, la mayor profundidad de la secci\u00f3n, menos pasadas, mayores radios de curvatura y relaci\u00f3n de espesor, y un mayor aumento del di\u00e1metro del rodillo de soporte, prolongar\u00e1n la longitud del producto. <\/span>Si la relaci\u00f3n entre el \u00e1rea total de los elementos doblados y el \u00e1rea total de los elementos rectos es alta, y la secci\u00f3n se forma con un n\u00famero adecuado de pasadas, entonces la longitud del producto terminado ser\u00e1 igual a la longitud de la tira inicial.<\/span><\/p>\n

Tolerancia de longitud de la m\u00e1quina formadora de rollos<\/strong><\/h2>\n

El m\u00e9todo de medici\u00f3n de longitud, el sistema de aceleraci\u00f3n de la matriz y la prensa tienen la mayor influencia en la tolerancia de longitud. <\/span>Adem\u00e1s, otros factores como el dise\u00f1o del rodillo tambi\u00e9n pueden influir en la tolerancia de longitud. <\/span>La diferencia de velocidad superficial en las superficies de conducci\u00f3n puede provocar una velocidad de conformado desigual. <\/span>Una gran diferencia entre las velocidades de la superficie del rodillo superior e inferior impulsados puede aumentar la tolerancia de longitud de 8 a 10 veces.<\/span><\/p>\n
