Description

Verfahren zur Herstellung von Tuben und anderen zylindrischen Behältern aus Blei, Zinn, Kupfer und anderen metallen und Legierungen, insbesondere aus Reinaluminium, nach dem als Spritzen bezeichneten Preßverfahren. Tuben und andere zylindrische Behälter aus Metallen, wie Zinn, Blei, Aluminium, werden bekanntlich durch eine als Spritzen bezeichnete Kaltumformung hergestellt. Als Ausgangsmaterial wurden bisher teils kreisrunde Scheiben, welche aus gewalzten Blechen des betreffenden Metalls ausgestanzt wurden, teils quadratische Platten, welche aus gepreßtem Flachkantmaterial abgeschnitten wurden, verwendet.Process for the production of tubes and other cylindrical containers made of lead, tin, copper and other metals and alloys, especially pure aluminum, according to the compression process known as spraying. Tubes and other cylindrical Containers made of metals such as tin, lead, aluminum, are known to be by a cold forming known as injection molding. As starting material were hitherto partly circular disks, which are made from rolled sheets of the relevant Metal were punched out, partly square plates, which were made of pressed flat edge material were cut off.

Bei dem weniger leicht formbaren Aluminium werden diese kreisrunden Scheiben oder quadratischen Platten nicht unmittelbar »gespritzt«, sondern erst vorgepreßt, d. h. in eine Form gebracht, welche der der Spritzmatrize entspricht. Das unmittelbare Spritzen der Scheiben und Platten wäre beim Aluminium nur mit einem erheblichen Werkzeugverbrauch und großem Ausschuß zu erkaufen. Nach den bisherigen Anschauungen konnte für eine so schwierige Umformung nur ein Metall in Frage kommen, das durch eine geeignete Vorbehandlung, wie es das Walzen und Pressen darstellt, genügend verfeinert ist.In the case of aluminum, which is less easily malleable, these become circular Panes or square plates are not "sprayed" immediately, but first pre-pressed, d. H. brought into a shape that corresponds to that of the injection mold. The direct spraying of the panes and plates would only be possible with aluminum to buy considerable tool consumption and large rejects. According to the previous ones Only one metal could be considered for such a difficult forming, through a suitable pretreatment, such as rolling and pressing, is refined enough.

Die Erfindung besteht darin, daß sie als Ausgangsmaterial runde Scheiben, quadratische Platten oder Vorpreßlinge aus gegossenem Material verwendet.The invention consists in the fact that they use round disks as the starting material, square plates or preforms of cast material are used.

Es hat sich gezeigt, daß gegossenes Material sich leichter spritzen läßt wie das durch Walzen oder Pressen vorbehandelte Material.It has been shown that cast material spatter more easily leaves like the material pretreated by rolling or pressing.

Die Erfindung ist von hervorragender technischer Bedeutung. Sie vereinfacht die Herstellung von Tuben und Behältern, insbesondere aus Aluminium, in erheblichem Maße, indem sie das Auswalzen der Bleche, das Pressen des Flachkantmaterials, das Ausstanzen der Ronden, das Abschneiden der Platten und das kostspielige Vorpressen überflüssig macht.The invention is of outstanding technical importance. You simplified the production of tubes and containers, in particular made of aluminum, in considerable Measure by rolling out the sheets, pressing the flat edge material, the Punching out the round blanks, cutting off the plates and costly pre-pressing makes redundant.

Das Gießen dichter und glattwandiger runder Scheiben und Platten als Preßlinge bietet beim Blei und Zinn keinerlei, beim Aluminium keine das Verfahren in Frage stellenden Schwierigkeiten. Jede der bekannten Gießarten, wie Kokillen-, Schleuder- und Spritzgut, führt zum Ziel.The casting of dense and smooth-walled round disks and plates as With lead and tin, no compacts are available, and the process does not offer any for aluminum questioning difficulties. Any of the known types of casting, such as mold, Centrifugal and sprayed material, leads to the goal.

Die Bruchflächen, welche beim Ausstanzen der runden Scheiben und Abscheren der Platten entstehen, verursachen bei der alten Herstellungsweise das Auftreten poröser und dadurch unbrauchbarer Tuben. Bei Verwendung dichter Preßlinge aus Gutmaterial treten poröse Tuben überhaupt nicht auf.The fracture surfaces that occur when the round disks are punched out and sheared off of the panels are caused by the old production method porous and therefore unusable tubes. When using dense compacts made of good material porous tubes do not appear at all.
