Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines wenigstens zweiteiligen Schmuckringes nach dem Oberbegriff des Anspruchs 1 sowie einen in einem entsprechenden Verfahren hergestellten Schmuckring. Der Schmuckring weist dabei einen Trägerring und wenigstens eine darin eingelassene Ausnehmung auf, die zur Aufnahme eines Einlageringes dient. Dieser wenigstens eine Einlagering besteht beispielsweise zur Erzeugung einer optischen Abstufung gegenüber einer Oberfläche des Trägerringes aus einem anderen Material wie dieser oder weist gegenüber dessen Oberfläche eine andere Farbgebung oder Oberflächenbeschaffenheit auf. Zur Herstellung des Ringes wird der wenigstens eine Einlagering zunächst auf den Trägerring aufgezogen. Hierzu weist der Einlagering einen Innendurchmesser auf, der minimal größer ist als ein Außendurchmesser des Trägerrringes. Mittels Aufbringung einer Ringspannung wird dann die Größe des Einlageringes an die Größe der Ausnehmung angepasst wodurch der Einlagering in der Ausnehmung positioniert wird.The invention relates to a method for producing an at least two-part jewelry ring according to the preamble of claim 1 and a jewelry ring produced in a corresponding method. The jewelry ring has a support ring and at least one recessed recess therein, which serves to receive a Einlageringes. This at least one insert ring, for example, to produce an optical gradation with respect to a surface of the support ring of a different material such as this or has with respect to the surface of a different color or surface finish. To produce the ring, the at least one insert ring is first drawn onto the carrier ring. For this purpose, the insert ring to an inner diameter which is minimally larger than an outer diameter of the Trägerrringes. By applying a ring tension then the size of the insert ring is adapted to the size of the recess whereby the insert ring is positioned in the recess.

Bei den bekannten Herstellungsverfahren solcher Ringe ist es üblich, den Einlagering von vornherein im Wesentlichen in der gewünschten Endgröße zu verwenden und diesen auf den Trägerring aufzuziehen. Der Trägerring liegt hierzu dagegen zunächst in einer Größe vor, die deutlich kleiner ist als die gewünschte Endgröße, so dass der Innendurchmesser des Einlageringes ausreichend groß ist, um über den Außendurchmesser des Trägerringes und geschoben werden zu können, um ihn über der Ausnehmung zu platzieren. Anschließend wird der Trägerring beispielsweise mittels eines Eisendoms aufgespreizt, wobei sich dessen Innen- und Außendurchmesser derart vergrößert, dass einerseits der Einlagering in der Ausnehmung aufgenommen ist und andererseits die gewünschte Endgröße des Innendurchmessers im Wesentlichen erreicht ist.In the known production method of such rings, it is customary to use the insert ring from the outset substantially in the desired final size and to raise this on the support ring. For this purpose, the carrier ring is initially in a size that is significantly smaller than the desired final size, so that the inner diameter of the insert ring is sufficiently large to be pushed over the outer diameter of the support ring and to place it over the recess. Subsequently, the carrier ring is spread open, for example by means of an iron dome, wherein the inner and outer diameter is increased such that on the one hand the insert ring is received in the recess and on the other hand, the desired final size of the inner diameter is substantially achieved.

Nachteilig an den bekannten Herstellungsverfahren ist, dass die dabei verwendeten Trägerringe bei den üblicherweise verwendeten Gold- oder Silberlegierungen nur in einem sehr begrenzten Maße aufgespreizt werden können. Folglich beträgt die Tiefe der Ausnehmung in der der Einlagering aufgenommen wird, üblicherweise höchstens 1,0 mm. Diese geringe aufnehmbare Materialstärke des Einlageringes reicht jedoch in vielen Fällen nicht aus, um im Bereich des Einlageringes beispielsweise eine Fassung für einen Edelstein herstellen zu können. Vielmehr kommt es beim Einlassen von Fassungen in derartige Einlageringe häufig zu Verformungen oder gar zu einem Bruch. Zudem kann bei den bekannten Herstellungsverfahren ein ausreichender Kraftschluss, der ein Verdrehen des Einlageringes gegenüber dem Trägerring verhindert, häufig nur durch einen zusätzlichen Glühvorgang gewährleistet werden, durch den jedoch wiederum die Materialhärte reduziert wird.A disadvantage of the known production method is that the support rings used in the case of the gold or silver alloys usually used can only be spread to a very limited extent. Consequently, the depth of the recess in which the insert ring is received is usually at most 1.0 mm. However, this low ingestible material thickness of the insert ring is in many cases not sufficient to be able to produce, for example, a socket for a gemstone in the region of the insert ring. Rather, it often comes when inserting versions in such Einlageringe deformations or even a break. In addition, in the known manufacturing process sufficient frictional connection, which prevents rotation of the insert ring relative to the support ring, often be ensured only by an additional annealing, by which, however, the material hardness is reduced.

Die Aufgabe der Erfindung ist es, bei einem gattungsgemäßen Herstellungsverfahren die genannten Nachteile zu vermeiden und die Verwendung von stärkeren Einlageringen zu ermöglichen.The object of the invention is to avoid the disadvantages mentioned in a generic manufacturing method and to allow the use of stronger Einlageringen.

Diese Aufgabe wird durch ein Verfahren zur Herstellung eines Schmuckringes mit den Merkmalen des Anspruchs 1 gelöst. Dabei wird die plastische Verformung mittels einer ringförmigen Druckspannung erzeugt, die an einer Außenseite des wenigstens einen Einlageringes aufgebracht wird und dabei radial nach innen gerichtet ist. Durch diese spezielle "Insert-Technik" erfolgt die Verbringung des Einlageringes in die Ausnehmung des Trägerringes durch plastische Verformung des Einlageringes, während die Größe des Trägerringes hierfür nicht geändert werden muss. Eine derartige Stauchung des Einlageringes kann dabei für übliche Gold-oder Silberlegierungen für Schmuckringe bis zu einer Materialstärke des Einlageringes von 1,6 mm durchgeführt werden. Bei dieser Materialstärke können in den Einlagering problemlos auch größere Fassungen für Steine, wie insbesondere Edelsteine, eingelassen werden. Zudem bewirkt die Stauchung des Einlageringes an diesem eine gewisse Querschnittsaufweitung, mittels der sich dieser sehr stabil in der Ausnehmung festklemmen kann. Hierdurch wird ein relativ hoher Kraftschluss zwischen dem Einlagering und dem Trägerring hergestellt durch den unerwünschte Relativbewegungen zwischen beiden Ringen verhindert werden können, ohne dass es eines zusätzlichen Glühvorganges bedarf.This object is achieved by a method for producing a decorative ring with the features of claim 1. In this case, the plastic deformation is generated by means of an annular compressive stress, which is applied to an outer side of the at least one insert ring and is directed radially inwardly. By this special "insert technique", the transfer of the insert ring into the recess of the carrier ring by plastic deformation of the insert ring, while the size of the support ring does not need to be changed for this purpose. Such a compression of the insert ring can be carried out for conventional gold or silver alloys for jewelry rings up to a material thickness of the insert ring of 1.6 mm. With this material thickness larger inserts for stones, in particular gemstones, can be easily embedded in the insert ring. In addition, the compression of the insert ring causes this at a certain cross-sectional widening, by means of which it can clamp very stable in the recess. As a result, a relatively high adhesion between the insert ring and the carrier ring is produced by the undesirable Relative movements between the two rings can be prevented without the need for an additional annealing process.

Vorteilhafterweise erfolgt die Aufbringung der ringförmigen Druckspannung dabei durch Einpressen des Trägerringes mit dem aufgezogenen Einlagering in eine zylindrische Stauchform mit konischem Eintrittsbereich. Hierdurch kann mit einfachen Mitteln eine gleichmäßige ringförmige Druckspannung auf die Außenseite des Einlageringes aufgebracht werden, durch die dieser über seinen Umfang hinweg gleichmäßig gestaucht wird, wobei sich sein Material bei der damit in Verbindung stehenden plastischen Verformung gleichmäßig in der Ausnehmung des Trägerringes verteilt.Advantageously, the application of the annular compressive stress is carried out by pressing the carrier ring with the mounted insert ring in a cylindrical compression shape with a conical inlet region. As a result, a uniform annular compressive stress can be applied to the outside of the insert ring by simple means by which it is evenly compressed over its circumference, with its material being distributed uniformly in the recess of the carrier ring during the plastic deformation associated therewith.

Dabei ist es günstig, wenn das Einpressen des Trägerringes mit wenigstens zwei aufgezogenen Einlageringen erfolgt, die jeweils über einer entsprechenden Ausnehmung positioniert sind. Hierdurch kann der Schmuckring zur Erzielung eines besonderen optischen Effekts mit mehreren Einlageringen versehen werden. Dabei ist die mögliche Zahl von an einem Trägerring einstauchbaren Einlageringen nach oben in soweit offen, als dass diese lediglich durch die Breite des Trägerringes und die Breite der Einlageringe beziehungsweise der entsprechenden Ausnehmungen sowie die benötigten Mindestrand- und Mindestzwischenabstände begrenzt ist.It is advantageous if the pressing in of the carrier ring takes place with at least two mounted Einlageringen, which are each positioned over a corresponding recess. As a result, the jewelry ring to achieve a special visual effect can be provided with several Einlageringen. In this case, the possible number of plug-in on a support ring Einlageringen upwards in extent open as that this is limited only by the width of the support ring and the width of the Einlageringe or the corresponding recesses and the required Mindestrand- and minimum clearances.

Vorteilhafterweise wird der Trägerring vor dem Einpressen in die Stauchform zunächst geringfügig aufgespreizt, wodurch der wenigstens eine aufgezogene Einlagering relativ stabil und exakt in radialer Richtung über der Ausnehmung festgelegt werden kann bevor der Einpressvorgang vorgenommen wird. Hierdurch kann sichergestellt werden, dass der Einlagering ohne zu verkanten in die für ihn vorgesehene Ausnehmung verbracht wird. Das geringfügige Aufspreitzen des Trägerringes kann dabei beispielsweise mittels Eintrieb eines Spreizdornes erfolgen.Advantageously, the carrier ring is first spread slightly before being pressed into the compression mold, whereby the at least one mounted insert ring can be fixed relatively stable and exactly in the radial direction over the recess before the press-fitting is carried out. This can ensure that the insert ring is spent without tilting in the recess provided for him. The slight Aufspreitzen the carrier ring can be done for example by means of input of an expanding mandrel.

Zudem ist es günstig, wenn der Trägerring nach Verbringen des Einlageringes in die Ausnehmung in einem nachfolgenden Schritt in axialer Richtung gestaucht wird. Auf diese Weise kann ein besonders hoher Kraftschluss zwischen dem Einlagering und dem Trägerring erzielt werden.Moreover, it is favorable if the carrier ring is compressed in the axial direction after the insert ring has been moved into the recess in a subsequent step becomes. In this way, a particularly high adhesion between the insert ring and the carrier ring can be achieved.

Vorteilhafterweise wird nach Verbringen des Einlageringes in die Ausnehmung in einem nachfolgenden Schritt eine spanabhebende Überarbeitung vorgenommen. Auf diese Weise können Unebenheiten, die beim Einstauchen des Einlageringes insbesondere an den Übergängen zwischen der Oberfläche des Einlageringes und der Oberfläche des Trägerringes auftreten können, entfernt werden.Advantageously, after removal of the insert ring in the recess in a subsequent step, a machined revision made. In this way, unevenness that can occur during insertion of the insert ring in particular at the transitions between the surface of the insert ring and the surface of the support ring can be removed.

Ferner wird die Aufgabe durch einen in einem der oben genannten Verfahren hergestellten Schmuckring gelöst, wobei dieser wenigstens einen Einlagering aufweist, der über eine Querschnittstiefe von wenigstens 1,4 mm in die Ausnehmung verbracht ist. Hierdurch ist es möglich, auch im Bereich des Einlageringes größere spanabhebende Nachbearbeitungen vorzunehmen, ohne dass es zu Verformungen oder gar einem Bruch an dem Einlagering kommt.Furthermore, the object is achieved by a jewelry ring produced in one of the abovementioned methods, wherein the latter has at least one insertion ring which is brought into the recess over a cross-sectional depth of at least 1.4 mm. This makes it possible to make even in the field of Einlageringes major machinable reworking without causing deformation or even a break on the insert ring.

Dabei ist es günstig, wenn in den Einlagering wenigstens eine Fassung zur Aufnahme eines Steines eingelassen ist. Wegen der relativ großen Tiefe des Einlageringes können dabei auch größere Steine problemlos gefasst werden.It is advantageous if at least one socket for receiving a stone is embedded in the insert ring. Because of the relatively large depth of the Einlageringes larger stones can be taken easily.

In einer weiteren vorteilhaften Ausführungsform des Schmuckringes nach einem der oben genannten Verfahren weist dieser wenigstens vier Einlageringe auf, wodurch insbesondere bei unterschiedlichen Oberflächen der Einlageringe ein besonderer optischer Effekt des fertigen Schmuckringes erzeugt werden kann.In a further advantageous embodiment of the jewelery ring according to one of the above-mentioned methods, the latter has at least four insert rings, whereby a particular optical effect of the finished jewelery ring can be produced, in particular with different surfaces of the insert rings.

Fig. 1 zeigt einen mit einem erfindungsgemäßen Verfahren hergestellten zweiteiligen Schmuckring 2, der einen Trägerring 4 und einen Einlagering 6 aufweist. Fig. 1 shows a two-part jewelry ring 2 produced by a method according to the invention, which has a support ring 4 and a bearing ring 6.

Wie aus Fig. 2 zu entnehmen ist, ist in eine Außenseite 8 des Trägerringes 4 eine Ausnehmung 10 in Form einer ringförmigen Nut eingelassen, die zur Aufnahme des Einlageringes 6 dient. Die Ausnehmung 10 weist hierzu eine Tiefe tN auf, die in etwa einer Stärke dE des Einlageringes 6 entspricht und beispielhaft 1,4 mm beträgt.How out Fig. 2 can be seen, a recess 10 is recessed in the form of an annular groove in an outer side 8 of the support ring 4, which serves to receive the Einlageringes 6. For this purpose, the recess 10 has a depth t N which corresponds approximately to a thickness d E of the insert ring 6 and is 1.4 mm by way of example.

In dem in Fig. 2 dargestellten Ausgangszustand weist der Einlagering 6 einen Innendurchmesser DiE auf, der geringfügig größer ist als ein Außendurchmesser DaT des Trägerringes 4.In the in Fig. 2 illustrated initial state, the insert ring 6 has an inner diameter DiE, which is slightly larger than an outer diameter DaT of the support ring 4th

Zur Herstellung des Schmuckringes 2 gemäß Fig. 1 wird der Einlagering 6 in einem ersten Schritt zunächst auf die Außenseite 8 des Trägerringes 4 aufgezogen und bezüglich einer Hauptachse A des Trägerringes 4 exakt in einen radialen Projektionsbereich der Ausnehmung 10 verschoben, wie in Fig. 3 dargestellt. Zur sicheren vorrübergehenden Festlegung des Einlageringes 6 in dieser Position kann der Trägerring 4 dann in einem zweiten Schritt beispielsweise mittels eines Spreizdomes 12 geringfügig aufgespreizt werden, wie durch strichpunktierte Linien dargestellt.For the production of the jewelry ring 2 according to Fig. 1 the insert ring 6 is first mounted in a first step on the outer side 8 of the support ring 4 and with respect to a main axis A of the support ring 4 exactly in a radial projection region of the recess 10 is displaced, as in Fig. 3 shown. For safe temporary fixing of the insert ring 6 in this position, the carrier ring 4 can then be slightly expanded in a second step, for example by means of a Spreizdomes 12, as shown by dotted lines.

Anschließend wird der Trägerring 4 zusammen mit dem aufgezogenen Einlagering 6 in einem dritten Schritt mittels eines Einpresskörpers 14 in eine zylindrische Stauchform 16 eingepresst, wie in Fig. 4 dargestellt. Hierbei wird eine Außenseite 18 des Einlagering 6 an eine konisch geformte Begrenzungsfläche 20 eines Eintrittsbereiches 22 angelegt, wie durch strichpunktierte Linien dargestellt, wobei eine nach innen gerichtete, ringförmige Druckspannung D erzeugt wird, die auf die Außenseite 18 einwirkt. Durch diese wird der Einlagering 6 plastisch verformt und in die Ausnehmung 10 verbracht bis der Einlagering 6 vollständig in dieser aufgenommen ist, wie ebenfalls durch strichpunktierte Linien dargestellt.Subsequently, the carrier ring 4 is pressed together with the mounted insert ring 6 in a third step by means of a press-fit body 14 in a cylindrical compression mold 16, as in Fig. 4 shown. In this case, an outer side 18 of the insert ring 6 is applied to a conically shaped boundary surface 20 of an entry region 22, as shown by dashed lines, wherein an inwardly directed, annular compressive stress D is generated, which acts on the outer side 18. Through this, the insert ring 6 is plastically deformed and spent in the recess 10 until the insert ring 6 is completely received in this, as also shown by dotted lines.

In einem fünften Schritt kann dann zur Erhöhung des Kraftschlusses zwischen dem Einlagering 6 und dem Trägerring 4 noch eine zusätzliche Axialstauchung des Schmuckringes 2 parallel zur Hauptachse A vorgenommen werden, die beispielsweise mittels zweier Stauchkörper 24 erfolgt, wie in Fig. 5 dargestellt.In a fifth step can then be made to increase the frictional connection between the insert ring 6 and the support ring 4, an additional axial compression of the jewelery ring 2 parallel to the main axis A, for example, by means of two compression body 24, as in Fig. 5 shown.

An dem Schmuckring 2 kann anschließend noch eine weitere Bearbeitung vorgenommen werden, wie beispielsweise mittels einer spanabhebenden Oberflächenbearbeitung, wodurch dieser schließlich eine Form entsprechend Fig. 6 annimmt. In einem weiteren Schritt kann noch eine Fassung 26 für einen Stein 28 in den Einlagering 6 eingebracht werden, wie in Fig. 7 dargestellt.On the jewelry ring 2 can then be made a further processing, such as by means of a machining surface treatment, whereby this finally a shape accordingly Fig. 6 accepts. In a further step, a socket 26 for a stone 28 can be introduced into the insert ring 6, as in FIG Fig. 7 shown.

Fig. 8 zeigt eine weitere Ausführungsform des Schmuckringes 2 die in gleicher Weise wie oben beschrieben hergestellt ist. Der Schmuckring 2 weist hierbei mehrere Ausnehmungen 10 auf, in die beim oben beschriebenen Stauchvorgang jeweils ein eigener Einlagering 6 eingestaucht worden ist. Die Anzahl von vier Einlageringen 6 beziehungsweise Ausnehmungen 10 ist hierbei lediglich beispielhaft zu verstehen. Fig. 8 shows a further embodiment of the jewelry ring 2 which is made in the same manner as described above. The jewelery ring 2 in this case has a plurality of recesses 10, in each case a separate insert ring 6 has been dipped in the upsetting process described above. The number of four Einlageringen 6 or recesses 10 is to be understood merely as an example.
