Abstract

Procedimiento y dispositivo para la detección de fisuras en la deformación por embutición profunda de piezas de trabajo metálicas (4) en una prensa de estirado (1) mediante captación de los ruidos producidos durante la deformación por medio de sensores (7, 8) de sonido corporal. Para ello, durante el proceso de embutición profunda se efectúa en la pieza de trabajo (4), en paralelo en el tiempo, una captación directa del sonido corporal en la zona de deformación y fuera de la zona de deformación (VZ). Mediante comparación de las señales de sonido corporal captadas se determinan señales con amplitud y frecuencia aproximadamente iguales, como señales de ruido de perturbación, y se eliminan por filtrado. Las señales de sonido corporal captadas en la zona de deformación (VZ) son analizadas con supresión de las señales de perturbación y utilizadas para la detección de fisuras.
