Factor de corrección Fe

Frecuencia de alimentación alternativa:Obtener el factor de corrección Fs de lo siguiente:1- Calcular X usando la siguiente formula:� � � f= Nueva frecuencia de alimentación, Hz� � � A= Área de la barra, mm2

� � � Ts= Nueva temperatura de la barra, ºC2- Localizar la línea de relación de aspecto para el tamaño de barras (usar AR=1 para barras redondeadas)3- Localizar el valor del cálculo de X en el eje X4- Leer el factor de corrección Fs del eje Y5- Usar Fs con los valores computados de Iacie Nuevo Iac= Idc para condiciones X Fs

Condiciones alternativas de emisividad:Obtener el factor de temperatura k de la siguiente forma:1- Si los parámetros de temperatura no cambiaron, k=12- Si cambiaron, localizar el isotermal para la nueva temperatura ambiente3- Ubicar la nueva temperatura de funcionamiento de barras en el eje X4- Leer el factor de temperatura k del eje Y5- Calcular el factor k por altura de la barra

Obtener el factor de corrección Fe de lo siguiente:1- Localizar la línea de la constante de emisividad para la nueva condición2- Localizar k.h en el eje X3- Leer el factor de corrección Fe del eje Y

Recommendations

Recomendaciones para el curvado, taladrado, punzonado y corteLas barras de Cuponal pueden ser facilmente dobladas, normal al plano o en el borde.Cuponal tiene menos memoria que el cobre, y como resultado una curva resulta más fácil de lograr. Sin embargo, se requiere un gran radio de cobre para permitir las siguientes características de acoplamiento entre el cobre y el aluminio. Las barras de Cuponal no deben doblarse alrededor del borde de un cuchillo.Los radios de curvatura recomendados para los tamaños estándar de barras rectangulares de cuponal se detallan en la tabla.La formación de la presión debe ser gradual y no por impacto.La perforación y el punzado se debe realizar después que el pliego se ha completado.

Punzado:La herramienta de punzado debe ser diseñada de la misma manera que para su uso con barras de cobre planas. Es importante que la matriz debe dar soporte adecuado lo más cerca posible al borde de cizallamiento.

Corte:Cuponal puede ser cortado usando los métodos que se aplicaron al alimunio. La alternativa con molienda de dientes de sierra con forma trapezoidal da buenos resultados y no es necesario desbarbar

Perforado:
