Description

Ausschn:ieden und Tiefen von Kupferscheiben o. (lgl. Das Ausschmieden und Tiefen von Kui)ferscheiben zii Schalen o. dgl. erfolgte bisher in der Weise, daß die Kupferscheibr im Ofen warm gemacht, sodann unter den Hammer gebracht und so lange ausgeschmiedet wurde, bis das Werkstück erkaltet und hart war. Dann wurde es von neuem im Ofen erwärmt, unter den Hammer gebracht und wieder bis zum Erkalten geschmiedet und getieft. Das wiederholte sich acht- bis zwölfmal. Für verhältnismäßig starkwancligc@ Schalen wird das Ausschmieden und Tiefen mit nur je einer Kupferscheibe vorgenommen. Sollen dünnwandige Kupferschalen hergestellt werden, so werden mehrere (etwa zwölf) Scheiben, nachdem sie zuvor einzeln ausgeschmiedet sind, zu einem Paket vereinigt und -eineinsam getieft.Cutting out and depths of copper washers or the like (lgl and depths of Kui) ferscheiben zii bowls o. the like. So far took place in the way, that the copper disc warmed up in the furnace, then put under the hammer and Forged until the workpiece was cold and hard. Then became reheat it in the oven, put it under the hammer and then cool it down again forged and deepened. This was repeated eight to twelve times. For proportionately starkwancligc @ shells are forging and deepening with just one copper washer each performed. If thin-walled copper shells are to be produced, several (about twelve) discs, after they have previously been individually forged, into a package united and deepened.

Die angegebene lange Bearbeitungszcit wird gemäß der vorliegenden Erfindung dadurch wesentlich abgekürzt, daß der Kupferscheihe bzw. den zu einem Paket vereinigten Kupferscheiben «ährei:d des Ausschmiedens und Tiefeis Wärnie zugeführt wird, z. B. mittels eines Gasbrenners, dessen Flamme die Kupfersüheibe bespült.The specified long processing time is in accordance with the present Invention significantly shortened by the fact that the copper sheet or to one Package of unified copper washers "egg: d of forging and deep ice supplied will, e.g. B. by means of a gas burner, the flame of which flushes the copper surface.

Eine zur Ausführung des Verfahrens dienende Einrichtung ist auf der Zeichnung schematisch vc#ranschaulicht.A facility that is used to carry out the procedure is available on the Drawing schematically illustrates.

Auf dem Amboß a ruht die Kupferscheibe c. die von dein Hammer L ausgeschrnif det wird. Neben ciern Anil:oß ist ein Gasbrenner d angeordnet, dessen Flamme elir- Scheibe c während der Bearbeitung bespült. Wenn bei dünnwandigen Kupferscheiben mehrere Stücke zugle:cli bearbeitet «erden sollen, werden statt einer Kupferscheibe c die zu einem Paket vereinigten Scheiben zugleich ausgeschmic det lind getieft. Versuche haben gezeigt, daß es nicht nötig ist, daß das oder die Werkstücke rotwarm bleiben, es genügt vielmehr, daß sie blauwarm bleiben, da sie auch dann noch genügend weich und dehnbar sind, um geschmiedet werden zu können. Auf diese Weise gelingt cs, Kupferschalen o. dgl. statt in acht bis zwölf in einer bis zwei Hitzen vollständig auszuschmieden und zu tiefen, so daß hierbei wesentlich an Herstellungskosten lind Zeit gespart wird.The copper washer c rests on the anvil a. those cut out by your hammer L will be. Next to the anil: a gas burner is arranged, the flame of which is Washer c washes during processing. If with thin-walled copper washers several pieces at the same time: cli processed «are to be grounded instead of a copper washer c the panes combined to form a package are simultaneously cut out and deepened. Tests have shown that it is not necessary for the work piece or work pieces to be red-hot stay, it is rather enough that they remain warm blue, since they are still sufficient are soft and ductile to be forged. In this way it succeeds cs, copper bowls or the like. Instead of eight to twelve in one or two heats completely forged out and too deep, so that this lind substantially in manufacturing costs Time is saved.

Ebenso wie Kupferscheiben kennen natürlich auch Scheiben und sonstige Werkstücke aus anderen Metallen oder Legierungen bearbeitet werden.Just like copper washers, of course there are also washers and others Workpieces made of other metals or alloys are processed.
