Description
Verfahren zur Herstellung von Ziüerndruckacheiben für Büromaschinen und Registrierkassen. Bis jetzt wurden solche Ziffernscheiben, bei denen die Ziffern wie bei Sehreibmaschi- nenty pen erhaben sein mussten, für kleinere Serien graviert oder, wenn sich die Herstel lung einer Gussform lohnte, in Spritzguss her gestellt oder, wenn die Rollen von Stahl sein mussten, im Gesenk gepresst. Das erste Ver fahren ist nicht rationell,
während die an dern mit erheblichen Werkzeugkosten ver bunden sind.
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung solcher Ziffern scheiben mittels Walzen, das eine rationelle Arbeitsweise ermöglicht.
In der Zeichnung ist die Wirkungsweise beispielsweise dargestellt. Fig. 1 ist ein sche matischer Grundruss, Fig. 2 eine Seiten ansicht der bei der Herstellung verwendeten Scheiben. Die zu prägende Scheibe 1 ist zwi- ehen zwei Stahlscheiben 2 durch .Schrauben auf einem Zahnrad 3 festgepresst. In einer Stahlscheibe 4, welche auf dem zweiten Zahn rad 5 festsitzt, sind die zu prägenden Zei chen 7 negativ eingraviert.
Durch ein Zahn rad 9 kann das eine Zahnrad 5 in Drehung versetzt werden, wodurch sich die beiden Scheiben 1 und 4 aufeinander abwälzen. Mit- tels der exzentrisch gelagerten Welle ö kann die Mutterscheibe 4 durch Drehen des Hebels 8 unter allmählichem Kleinerwerden des Achsabstandes der sich abwälzenden Schei ben gegen die zu prägende Scheibe 1 gepresst werden. Das: Material, welches dadurch auf der Scheibe 1 verdrängt wird, füllt die in der härteren Mutterscheibe 4 vertieft eingravier ten Zeichen aus, wodurch dieselben auf der zu prägenden Scheibe 1 in positiver Form entstehen.
Process for the production of Ziüerndruckacheiben for office machines and cash registers. Up until now, such dials, where the digits had to be raised like typewriters, were engraved for smaller series or, if the production of a mold was worthwhile, made by injection molding or, if the rollers had to be made of steel, in Die-pressed. The first procedure is not rational
while others are associated with considerable tool costs.
The present invention relates to a method for the production of such numeric disks by means of rollers, which enables efficient operation.
In the drawing, the mode of operation is shown for example. Fig. 1 is a schematic plan view, Fig. 2 is a side view of the discs used in the manufacture. The disc 1 to be embossed is pressed firmly between two steel discs 2 by means of screws on a gear 3. In a steel disk 4, which is stuck on the second gear wheel 5, the characters to be embossed 7 are negatively engraved.
A gear wheel 9 can set a gear 5 in rotation, whereby the two disks 1 and 4 roll on each other. By means of the eccentrically mounted shaft 6, the nut disk 4 can be pressed against the disk 1 to be embossed by turning the lever 8 while the axial distance between the rolling disks gradually decreases. The: Material, which is thereby displaced on the disk 1, fills the indented characters in the harder mother disk 4, whereby the same arise on the disk 1 to be embossed in positive form.
