Description

Verfahren zur Herstellung nahtloser Zinkbecher Durch Patent 584 o62 ist ein Verfahren zur Herstellung nahtloser Zinkbecher für Trockenbatterien geschützt, bei welchem zunächst aus einer Zinkblechscheibe durch Umbördeln ein Napf gebildet . und die Wand dieses Napfes durch Auswalzen auf Fertiglänge zur Becherwand weiterverarbeitet wird. Die Erfindung betrifft eine Weiterbildung dieses Verfahrens in der Weise, daß als Ausgangsmaterial an Stelle von mechanisch durchgearbeitetem Zink (Zinkblech) gegossenes Zink verwendet wird. Die Erfindung beruht auf der Erkenntnis, daß das mechanische Durcharbeiten der Zinkrohlinge entbehrt werden kann, wenn bei der Formgebung des Zinkbechers selbst wie bei dem Verfahren nach dem Hauptpatent ein Stauchen und Walzen des Materials stattfindet. Der Wegfall eines Arbeitsganges ist aber gerade bei der Fabrikation einer Massenware, wie sie Zinkbecher für Trockenbatterien darstellen, von größter Bedeutung.Method of Making Seamless Zinc Cups By Patent 584o62 is a method of making seamless zinc cans for dry battery protected, in which a bowl is initially formed from a sheet zinc disc by flanging . and the wall of this cup is further processed by rolling to the finished length to form the cup wall will. The invention relates to a further development of this method in such a way that that as a starting material instead of mechanically worked zinc (zinc sheet) cast zinc is used. The invention is based on the knowledge that Mechanical work through of the zinc blanks can be dispensed with when shaping of the zinc cup itself, as in the method according to the main patent, a upsetting and Rolling of the material takes place. The elimination of a work step is just now in the manufacture of mass-produced goods, such as the zinc cups for dry batteries, of highest importance.

Es ist zwar bekannt, Tuben und ähnliche Behälter aus Metallen, wie Blei, Zinn, Kupfer und Aluminium, nach dem als Spritzen bezeichneten Preßverfahren aus gegossenen Blöckchen herzustellen. Es handelt sich jedoch hierbei nicht wie beim Erfindungsgegenstand um die Herstellung von Zinkbechern für Trockenelemente, bei welchen es in erster Linie auf das elektrochemische Verhalten des Materials im Element ankommt. Auch ist der Werkstoff des angemeldeten Verfahrens, das Zink, als mechanisch schwerer verarbeitbar bekannt als die genannten geschmeidigen Metalle; auf die sich das bekannte Verfahren bezieht.Although it is known, tubes and similar containers made of metals, such as Lead, tin, copper and aluminum, using the pressing process known as spraying made from cast blocks. However, this is not how in the subject matter of the invention to the production of zinc cups for drying elements, in which it is primarily due to the electrochemical behavior of the material arrives in the element. The material of the registered process, zinc, is also known to be more difficult to process mechanically than the aforementioned malleable metals; to which the known method relates.

Die Herstellung eines nahtlosen Zinkbechers erfolgt nach obiger Erfindung in der Weise, daß von einer gegossenen. Zinkscheibe ausgegangen wird, aus dieser durch einen Stauchvorgangr ein gegebenenfalls in mehreren Stufen erfolgendes Umbördeln, ein Napf gebildet und alsdann die Wand dieses Napfes auf die endgültige Höhe und Wandstärke des fertigen Bechers ausgewalzt wird. Der fertige Zinkbecher kann rund oder unrund sein.A seamless zinc cup is produced according to the above invention in such a way that from a cast. Zinc disc is assumed from this by means of an upsetting process, possibly in several stages, a cup is formed and then the wall of this cup to the final height and Wall thickness of the finished cup is rolled out. The finished zinc cup can be round or be out of round.
