Abstract

Dispositivo para amortiguar fuerzas que aparecen de repente en máquinas, tales como el choque o impacto de corte en cizallas y estampas, en las cuales un útil movible es guiado frente a un útil fijo en el bastidor de la máquina y el pistón amortiguador de un cilindro amortiguador fijamente unido con el útil estacionario es desplazable dentro del cilindro amortiguador con desplazamiento de un medio de presión desde este cilindro, en donde con carga creciente, un paso de medio de presión entre un pistón de control y su cilindro de control a través de un movimiento relativo conseguido por la carga de la pieza de trabajo a trabajar, disminuye hasta un valor mínimo en un momento de máxima carga, y después de ello el medio de presión puede ser evacuado a través de una estrangulación, caracterizado porque el pistón amortiguador es movible en la línea de acción del útil movible y contiene en dirección axial el cilindro de control, cuyo pistón de control está fijo en el fondo del cilindro amortiguador, pero está dispuesto de modo ajustable por todo el camino de carrera del útil movible , desembocando una conducción de aportación de medio de presión a través del pistón de control dentro del cilindro de control y siendo cerrable mediante una válvula de retención.
