R.Scheuchl GmbH: News + Job offer

The R. Scheuchl GmbH with registered office in Ortenburg (near Passau) has produced a highly flexible and fully automatic casting finishing line for cylinder heads for a Bavarian automotive manufacturer.

With this installation three different cylinder head types can be decored, sawed, freed of chips and they are provided with a data-matrix-code. A maximum of flexibilty is thereby of highest importance. Thus, the R. Scheuchl GmbH has realised a concept where three different casting types can be treated without changeover measures.

The cylinder heads from the gravity casting line are put into casting pallets. Afterwards they are led towards the casting finishing line by means of a tooth belt conveyor. In order to compensate production differences between the foundry line and the casting finishing line, the R. Scheuchl GmbH has installed a buffer in which 60 castings can be stored temporarily.

In the casting finishing-line the position coordinates of the casting are determined by means of an innovative laser-identification-system. Then they are forwarded directly to the decoring robot. Before the casting is put into one of the two decoring machines, the front intake is sawed off in a robot-sawing-unit. The decoring machines consist of oscillation decoring machines type Shake Champion SC 320 with integrated pre-decoring. Firstly the casting is hammered up with decoring hammers. Afterwards the sand is jolted out of the castings by oscillation with high frequency and especially high osciallation amplitude. The result is a complete and reliable removal of sand of the castings within the requested cycle time.

After the decoring process the castings are checked for core-breaking with different sensors. Depending on the result, the front side as well as the inlet- and outlet side are sawed in a robot sawing process.

The valve side and the combustion chamber side are both treated with a flexible tri-axial-circular saw. Depending on the casting type, different, freely programmable sawing parameter sets are available.

After the sawing process the casting is freed from saw dust in a blowing-jolting-station. By using the blowing-jolting-station it has been accomplished to meet the especially ambitious aim of the customer concerning the tolerable content of rest-sand within the casting.

After all handling steps the casting is labelled with a data-matrix-code in a separate laser embossing station. With a buffer-conveyor the casting is fed a following x-ray-unit.

The arising core sand is transported into a sand conditioning plant over a jolting channel and a belt-conveyor. Chips and sawed aluminium parts are conveyed into a collecting container.
