Abstract

An impact device and a turning device are arranged with a sound-insulating cabin and are operatively connected with one another through roller conveyors and lifting tables. Castings conveyed into the decoring station by means of conveyor pallets are clamped in a clamping frame. An impact device for decoring the casting imparts percussions on the clamping frame. Subsequently, the loosened core sand is removed from the casting in a turning device.
