Abstract
Procedimiento para la regulación de la dosificación de metal en la fabricación de una multiplicidad de piezas de fundición (3) con una celda de fundición a presión, en el que una cantidad de metal líquido, determinada en cada caso a través de su peso de dosificación, se introduce en una cámara de llenado y con un émbolo de presión (2) se presiona al interior de un molde de fundición (1) y en el molde de fundición (1) se solidifica formando una de las piezas de fundición (3), comprendiendo el procedimiento una regulación de una longitud de residuo de prensado (5) con los siguientes pasos: a) la medición continua de la longitud de residuo de prensado (5) como longitud de un residuo de prensado (4) de las piezas de fundición (3) fabricadas; b) la determinación de una diferencia de regulación mediante la comparación de la longitud de residuo de prensado (5), o de una magnitud derivada a partir de ello, con un valor promedio de un intervalo de tolerancia; c) el ajuste de un parámetro de ajuste de la celda de fundición a presión que influye en el peso de dosificación en función de la diferencia de regulación determinada, de tal forma que se minimiza la diferencia de regulación, siendo compensado automáticamente un cambio de la cantidad de dosificación resultante de una corrección de dosificación sistemática predefinida.Procedure for the regulation of metal dosing in the manufacture of a multiplicity of castings (3) with a die-cast cell, in which a quantity of liquid metal, determined in each case through its dosing weight , it is introduced into a filling chamber and with a pressure plunger (2) it is pressed into a casting mold (1) and in the casting mold (1) it solidifies forming one of the castings (3) , the method comprising a regulation of a length of pressing residue (5) with the following steps: a) the continuous measurement of the length of pressing residue (5) as the length of a pressing residue (4) of the pieces of cast iron (3) manufactured; b) the determination of a regulation difference by comparing the length of the pressing residue (5), or of a magnitude derived therefrom, with an average value of a tolerance range; c) the adjustment of a setting parameter of the die-casting cell that influences the dosing weight based on the determined regulation difference, such that the regulation difference is minimized, a change in the compensation being automatically compensated dosage amount resulting from a predefined systematic dosage correction.
Description
de efecto tardío. Al realizar un procedimiento según la invención con detección de residuo de prensado, por lo tanto, los valores de corrección n y Reducción_kg pueden ser optimizados automáticamente, en lugar de variar directamente el peso de dosificación ajustado. of late effect. When performing a method according to the invention with detection of pressing residue, therefore, the correction values n and Reduction_kg can be optimized automatically, instead of directly varying the adjusted dosing weight.
5 La figura 6 muestra en una representación esquemática una regulación de los pesos de dosificación ajustados en función de los pesos de dosificación reales de las piezas de fundición 3 fundidas. En la figura 6a) está representada la evolución de los pesos de dosificación ajustados durante la realización de la regulación, mientras que la figura 6b) muestra los pesos de las piezas de fundición 3 fundidas, calculados a partir del residuo de prensado 4, así como los límites 9 del intervalo de tolerancia. Dentro de los límites 9 superior e inferior varía el peso real de las piezas de 5 Figure 6 shows in a schematic representation a regulation of the adjusted dosage weights based on the actual dosage weights of the castings 3 castings. In figure 6a) the evolution of the adjusted dosing weights during the regulation is shown, while figure 6b) shows the weights of the castings 3 cast, calculated from the pressing residue 4, as well as the limits 9 of the tolerance interval. Within the upper and lower limits 9 the actual weight of the pieces of
10 fundición 3, calculado a partir del residuo de prensado 4. El valor promedio 10 de los pesos de pieza de fundición reales se mantiene en el centro del intervalo de tolerancia por la regulación de los pesos de dosificación. Dado que todos los pesos de pieza de fundición pueden mantenerse dentro de los límites 9 del intervalo de tolerancia, en el caso representado en la figura 6 no se producen piezas de desecho. Las diferencias de peso entre el peso de dosificación ajustado y el peso calculado de las piezas de fundición fundidas resultan por ejemplo por metal que se 10 foundry 3, calculated from the pressing residue 4. The average value 10 of the actual foundry weights is kept at the center of the tolerance range by regulating the dosing weights. Since all weights of cast iron can be kept within the limits 9 of the tolerance range, in the case shown in Figure 6 no scrap parts are produced. The weight differences between the adjusted dosing weight and the calculated weight of the castings are, for example, by metal which is
15 ha depositado dentro del tubo de dosificación o que se queda en la acanaladura. Este metal, a pesar de haber sido dosificado, no ha llegado a la cámara de fundición. Los depósitos de óxido en el canto de paso del tubo de dosificación cambian el nivel de presión hidrostática de referencia e igualmente repercuten en el peso de dosificación. También sería posible que se está usando un nuevo tubo de dosificación con medidas distintas o que se está produciendo una mezcla de la nueva masa fundida introducida y la que aún permanece en el sistema, lo que 15 has deposited inside the dosing tube or remains in the groove. This metal, despite having been dosed, has not reached the casting chamber. The oxide deposits in the passage of the dosing tube change the reference hydrostatic pressure level and also have an impact on the dosing weight. It would also be possible that a new dosing tube with different measures is being used or that a mixture of the new melt introduced and the one that still remains in the system is being produced, which
