Description
Verfahren zur Herstellung von verchromten Uhrgehäusen Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von verchromten Uhrgehäusen mit Mehrfarbenwirkung auf galvanischem Wege.Process for the manufacture of chrome-plated watch cases The invention relates to a process for the production of chrome-plated watch cases with a multicolor effect by galvanic means.
Es ist bekannt, bei Uhrgehäusen die Lünette ohne Glasansatz herzustellen. Dieser beispielsweise verchromte Lünettenteil weist sodann eine Ringausdrehung auf, in welche der besonders, z. B. aus einer Goldlegierung gefertigte Glasrand mittels Ansatz eingesprengt oder eingelötet ist. Hierdurch wurde eine aus zwei Metallen gebildete Lünette mit Mehrfarbenwirkung geschaffen; die besondere Anbringung des Glasansatzes an der Lünette, insbesondere die Lötung, ist fabrikationstechnisch umständlich und zeitraubend. Diese Uhrgehäuse sind somit auch verhältnismäßig teuer.It is known to produce the bezel without a glass attachment in watch cases. This, for example, chrome-plated bezel part then has a ring recess, in which the particularly, z. B. made of a gold alloy by means of glass rim Approach is blown in or soldered in. This made one of two metals formed bezel created with multicolor effect; the special attachment of the The glass attachment on the bezel, especially the soldering, is manufacturing technology cumbersome and time consuming. These watch cases are therefore also relatively expensive.
Es ist ferner bekannt, bei Metallgeräten die Mehrfarbenwirkung durch Teiltauchung oder Aussparlacke zu erzielen. Aus diesen bekannten Verfahren wurde nun ein für verchromte Uhrgehäuse mit Mehrfarbenwirkung besonders zweckmäßiges Verfahren entwickelt, welches sich entgegen jeglichen Vorurteilen als einfacher und billiger erwies als die bekannten Verfahren.It is also known to use multi-color effects in metal devices To achieve partial immersion or recess varnishes. From these known processes became now a particularly useful process for chrome-plated watch cases with a multicolored effect which, contrary to all prejudices, turns out to be simpler and cheaper proved to be the known method.
Das neue Verfahren ist nun dadurch gekennzeichnet, daß zunächst die nicht zu vergoldenden Oberflächenteile der vorgedrehten Lünette, und zwar entweder die Hornpartie oder der Glasrand, glanzgedreht werden, daß anschließend die ganze Lünette galvanisch verchromt wird, daß dann nacheinander die ganze Oberfläche des Uhrgehäuses abgedeckt wird, die zu vergoldenden Flächenteile glanzgedreht und galvanisch mit Gold überzogen werden, worauf die Lünette nach Entfernen des Abdeckmittels glanzpoliert wird. Dadurch wird erreicht, daß nur ein einfaches Tauch- oder Spritzverfahren erforderlich ist und nur an den zu vergoldenden Oberflächenteilen Gold abgeschieden wird.The new method is now characterized in that initially the surface parts of the pre-turned bezel that are not to be gold-plated, namely either the horn part or the edge of the glass, be polished, that then the whole Bezel is galvanically chrome-plated, so that one after the other the entire surface of the Watch case is covered, the surface parts to be gilded are polished and electroplated be coated with gold, whereupon the bezel is polished to a shine after removing the covering agent will. This means that only a simple immersion or spraying process is required and gold is only deposited on the parts of the surface to be gold-plated.
Durch diese erfindungsgemäße Reihenfolge der einzelnen Arbeitsgänge wird das Verfahren zur Erzeugung von Uhrgehäusen mit Mehrfarbenwirkung besonders wirtschaftlich gestaltet.Through this sequence of the individual operations according to the invention the process for the production of watch cases with a multicolored effect becomes special economically designed.
Um in besonderen Fällen eine Beschädigung des Abdecklackes an den Schnittkanten beim Glanzdrehen der zu vergoldenden Flächenteile zu vermeiden, können auch nach dem Verchromen zunächst die zu vergoldenden Oberflächenteile glanzgedreht und dann nach dem Glanzdrehen und Abdecken der verchromt bleibenden Oberflächenteile vergoldet werden.In order to avoid damage to the masking varnish in special cases Avoid cutting edges when turning the surface parts to be gilded with a gloss finish even after chrome-plating, the surface parts to be gold-plated are turned with a high-sheen finish and then after the gloss turning and covering of the remaining chrome-plated surface parts to be gold-plated.
