Centrifugal jet machine

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.

Apparatus for the decoring of castings

A holding device for workpieces, which is rotatably mounted in the side-walls of a centrifugal blasting machine, including a support member and holding member. Both members are pivotably mounted diametrically opposed with respect to the axis of rotation. By means of a pivot drive, both members can be simultaneously moved toward one another and away from one another. Through this, the holding device can be adjusted in each given case in such a manner, so that workpieces of different height can be retained in a centralized position with respect to the axis of rotation, in order to subject them in a rotating manner to a uniform centrifugal blasting treatment.

Centrifugal blasting machine having a rotatable workpiece holder

A rotatable drum having a plurality of receiving stations for loading workpieces to be processed is rotated about a horizontal central axis through a plurality of work stations including at least one blasting station and a loading and unloading station. Each receiving chamber forms a sealed blasting chamber in the area of the blasting process station and flow off of the blasting medium and the blasted particles occurs by an arrangement of flow off channels defined between each of the receiving chambers and connected with the chambers in a labyrinthine manner in the central area of the drum.
