Description

Verfahren zum Warmtiefziehen Zusiitz zum Patent 677 9z Im Hauptpatent ist ein Verfahren angegeben worden, mittels dessen Bleche aus Magnesiumlegierungen tiefgezogen werden können mit Hilfe eines Schmiermittels, bestehend aus mittels Gelatine o. dgl. wassergebundenem, zweckmäßig kolloidalem Graphit unter Vermeidung von Öl und Fett, wobei die Geschwindigkeit des zunächst auf das Werkstück aufgesetzten Ziehstempels, vom Ruhezustand ausgehend, allmählich gesteigert wird und wobei z@@,eckmäßig ein beheizter Faltenlialterring mit einem der Abrundung der Ziehkante der Ziehmatrize entsprechend abgerundeten, dem zu ziehenden Blech zugekehrten Wulstrand verwendet ist, so daß beim Niedergehen des Stempels auf (las Ziehblech dieses unter Wärmezufuhr über einen Teil der Ziehkante geführt wird.Process for hot deep drawing Zusiitz for patent 677 9z in the main patent a method has been specified by means of which sheets of magnesium alloys can be deep drawn with the help of a lubricant consisting of means Gelatine or the like water-bound, expediently colloidal graphite, avoiding it of oil and grease, the speed of which is initially placed on the workpiece Drawing punch, starting from the state of rest, is gradually increased and where z @@, angular a heated fold ring with one of the rounded edges of the drawing edge of the drawing die appropriately rounded beaded edge facing the sheet to be drawn is used is, so that when the punch goes down on (read the draw sheet this with the supply of heat is guided over part of the pulling edge.

Neuere Untersuchungen haben gezeigt, daß dieses Ziehverfahren nicht nur für Bleche aus Magnesiuinlegierungen, sondern auch für solche aus Aluminiumlegierungen, insbesondere mit hohem Magnesiumgehalt, sehr gut geeignet ist und es dadurch möglich macht, aus Blechen aus den ,bekanntlich schwer ziehbaren Aluminiumlegierungen tiefe Hohlkörper zu ziehen. Dadurch ist den Aluminiumlegierungen ein Anwendungsgebiet eröffnet worden, das ihnen bisher verschlossen. war.Recent research has shown that this drawing process does not only for sheets made of magnesium alloys, but also for those made of aluminum alloys, especially with a high magnesium content, is very suitable and thus possible makes deep sheet metal from aluminum alloys, which are known to be difficult to draw To pull hollow body. This makes aluminum alloys an area of application which has been closed to them until now. was.

Die Einzelheiten des neuen Tiefziehverfahrens sind im wesentlichen dieselben, wie im Hauptpatent angegeben.The details of the new deep drawing process are essential the same as stated in the main patent.
