Abstract
Mit einem Verfahren zum Fassen vom Edelsteinen, insbesondere von Brillanten in Edelmetallen oder deren Legierungen, wobei der Edelstein von dem die Fassung bildenden Metall wenigstens bereichsweise umgriffen wird soll eine Lösung geschaffen werden, mit der auf maschinelle Weise Edelsteine, insbesondere Brillanten, gefaßt werden können, wobei die maschinellen Vorbereitungen auf ein Mindestmaß reduzierbar und damit der Fassungsvorgang beschleunigbar ist.With a method for setting gemstones, in particular diamonds in precious metals or their alloys, whereby the gemstone is at least partially encompassed by the metal forming the setting, a solution is to be created with which gemstones, in particular diamonds, can be mechanically set. whereby the machine preparations can be reduced to a minimum and thus the mounting process can be accelerated.
Dies wird dadurch erreicht, daß der Edelstein (3) unter Druck in eine Bohrung (2) eingepreßt wird, deren Durchmesser (b) geringfügig kleiner ist als der Außendurchmesser (a) des zu fassenden Edelsteines, und daß nach Eintreiben der äußeren Randbereiche des Edelsteines in das Bohrloch unter das Oberflächenniveau des Fassungsmetalles von oben Metallmaterial über die äußeren Randbereiche des zu fassenden Steines gerieben wird. This is achieved in that the gem (3) is pressed under pressure into a bore (2), the diameter (b) of which is slightly smaller than the outside diameter (a) of the gem to be set, and after driving in the outer edge areas of the gem into the borehole below the surface level of the socket metal from above metal material is rubbed over the outer edge areas of the stone to be gripped.
Description
Die Erfindung ist hier auf ein Verfahren und eine Vorrichtung zum Fassen von Edelsteinen, insbesondere von Brillanten und Edelmetallen oder deren Legierungen, wobei der Edelstein von dem die Fassung bildenden Metall wenigstens bereichsweise umgriffen wird.The invention here relates to a method and a device for setting precious stones, in particular diamonds and precious metals or their alloys, the precious stone being encompassed at least in regions by the metal forming the setting.
Es sind eine Reihe von Verfahren bekannt, Edelsteine zu fassen, etwa durch Einsetzen in vorbereitete kronenförmige Fassungselemente, die nach außen weisende Krampen tragen, die nach Fassung des Edelsteines diesen bereichsweise außen umgreifen, wie dies beispielsweise in der US-PS 2 533 870 beschrieben ist. Eine im wesentlichen maschinelle Art der Vorbereitung derartiger Kronen zeigt die DE-OS 32 37 490, eine im Prinzip gleiche Fassungsart ist in der FR-A- 2 579 428 beschrieben.A number of methods are known for setting gemstones, for example by inserting them into prepared crown-shaped setting elements which carry outwardly facing cramps which, after setting the gemstone, grasp the outside thereof in regions, as is described, for example, in US Pat. No. 2,533,870 . DE-OS 32 37 490 shows an essentially mechanical way of preparing such crowns; a basically identical type of version is described in FR-A-2 579 428.
Die FR-A- 2 428 990 zeigt ein zur maschinellen Fassung von Edelsteinen geeignetes Verfahren bei dem eine querschnittlich im wesentlichen U-förmige Schiene mit Aufnahmenuten für Randbereiche der geschliffenen Edelsteine aufweist. Die Edelsteine werden in dieser Schiene hintereinander aufgereiht, maschinell wird dann das durch die Nut geschwächte Material um die Randbereiche der zu fassenden Edelstei ne herumgebogen. Die Fassung eines Einzelsteines in ähnlicher Ausgestaltung zeigt die alte französiche Patentschrift 450 811.FR-A-2 428 990 shows a method suitable for the mechanical setting of gemstones, in which a cross-sectionally substantially U-shaped rail with receiving grooves for edge areas of the cut gemstones. The gemstones are lined up one behind the other in this rail, the material weakened by the groove is then machined around the edge areas of the gemstone to be grasped ne bent around. The version of a single stone in a similar design shows the old French patent specification 450 811.
Das Fassen eines Edelsteines mittels eines Gesenkes in einen vorbereiteten Sitz bei dem dann später auch über ein Gesenk die oberen geschlitzten Randbereiche des Fassungsmateriales umgebogen werden zeigt die DE-OS 19 64 487. Eine ähnliche Fassungsart zeigt die US-4 761 865.DE-OS 19 64 487 shows the grasping of a gemstone by means of a die in a prepared seat, in which the upper slotted edge areas of the setting material are then later bent over a die. A similar type of setting is shown in US Pat. No. 4,761,865.
Gegenüber diesen bekannten Verfahren zeigt die EP-A 0 221 248 der Anmelderin ein weiter entwickeltes Verfahren zur Fassung von Edelsteinen in Rohrabschnitten. Bei diesem bekannten Verfahren wird ein Edelstein in einen Rohrabschnitt eingesetzt, der im Innendurchmesser geringfügig größer ist, als der Außendurchmesser des Edelsteines. Nunmehr wird über ein Gesenk das Rohrmaterial in sich verjüngender Weise verformt, derart, daß es um die Randbereiche des zu fassenden Edelsteines herum gequetscht wird, wodurch der Stein sicher und fest in dem Rohrabschnitt gehalten wird.Compared to these known processes, the applicant's EP-A 0 221 248 shows a further developed process for setting gemstones in pipe sections. In this known method, a gemstone is inserted into a pipe section which has a slightly larger inside diameter than the outside diameter of the gemstone. Now the pipe material is deformed in a tapered manner via a die, in such a way that it is squeezed around the edge regions of the gem to be gripped, as a result of which the stone is held securely and firmly in the pipe section.
Es gibt Einsatzgebiete in denen rohrförmige Fassungen weniger geeignet sind, etwa Fassungen in Aufnahmebohrungen von Ringschienen oder insbesondere in dünnen Schmuckmetalbechen. Hier läßt sich eine Gesenkverformung nicht mehr vornehmen. Aus der DE 33 07 817-A1 ist es bekannt, einen Edel stein in eine besonders gestaltete Bohrung eines Zifferblattes einzusprengen, in der Weise, daß sich das Randmetall federnd um den zu fassenden Brillanten legt. Dort ist allerdings nicht erkannt worden, daß der Edelstein selbst ein Werkzeug darstellen kann.There are areas of application in which tubular sockets are less suitable, such as sockets in receiving bores of ring rails or in particular in thin jewelry metal cups. It is no longer possible to deform the die here. From DE 33 07 817-A1 it is known a noble stone into a specially designed hole in a dial, in such a way that the edge metal resiliently wraps around the brilliant-cut diamond. However, it was not recognized there that the gem itself can be a tool.
Aufgabe der Erfindung ist daher Schaffung einer Lösung mit der auf maschinelle Weise Edelsteine, insbesondere Brillanten, gefaßt werden können, wobei die maschinellen Vorbereitungen auf ein Mindestmaß reduzierbar und damit der Fassungsvorgang beschleunigbar ist.The object of the invention is therefore to create a solution with which gemstones, in particular diamonds, can be set in a mechanical manner, the machine preparations being reduced to a minimum and the setting process thus being accelerated.
Mit einem Verfahren der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, daß der Edelstein unter Druck in eine Bohrung eingepreßt, deren Durchmesser geringfügig kleiner ist als der Außendurchmesser des zu fassenden Edelsteines, wobei vom Edelstein dabei das Bett selbst geformt wird, und daß nach Eintreiben der Außenrandbereiche des Edelsteines in das Bohrloch unter das Oberflächenniveau des Fassungsmetalles von oben Metallmaterial über die äußeren Randbereiche des zu fassenden Steines gerieben wird.With a method of the type mentioned, this object is achieved according to the invention in that the gemstone is pressed under pressure into a bore whose diameter is slightly smaller than the outside diameter of the gemstone to be grasped, the bed itself being formed by the gemstone, and that after driving the outer edge areas of the gemstone into the borehole below the surface level of the setting metal, metal material is rubbed from above over the outer edge areas of the stone to be gripped.
Mit diesem Verfahren wird z. B. die Vorbereitung eines Bettes für den Edelstein entbehrlich gemacht, da dieser beim Eindrückvorgang in das Edelmetall sich sein Bett selber schafft. Dabei wird Material von der Bohrlochinnenwand vor dem sich eindrückenden Edelstein hergetrieben, derart, daß ein Auflagewulst entsteht, der exakt den Außenkonturen des jeweils individuellen Edelsteines entspricht. Wird nun im zweiten Arbeitsgang von oben Material über Randbereiche des Edelsteines gerieben, so sitzt der Edelstein völlig fest in seiner Fassung. Dabei kann erreicht werden, daß nur ganz minimale Randbereiche vom Fassungmetall übergriffen werden, so daß optisch praktisch der gesamte Stein zur Wirkung kommt.With this method z. B. the preparation of a bed for the gem made unnecessary, since this creates its own bed during the pressing process into the precious metal. In doing so, material is placed in front of the inner wall of the borehole driven the impressing gemstone, such that a support bead is created that corresponds exactly to the outer contours of each individual gemstone. If material is rubbed over edge areas of the gemstone from above in the second step, the gemstone sits completely firmly in its setting. It can be achieved that only very minimal edge areas are covered by the frame metal, so that optically practically the entire stone comes into effect.
In Ausgestaltung sieht die Erfindung vor, daß in ein Schmuckblech eine Mehrzahl von Löchern eingebracht wird, deren Durchmesser geringfügig kleiner ist als der Außendurchmesser der zu fassenden Steine, diese danach gemeinsam in die Löcher über einen Preßstempel eingetrieben und die freien oberen Bereiche der äußeren Kontur nachfolgende angerieben werden. Damit lassen sich maschinell eine Vielzahl von Schmucksteinen fassen, insbesondere in dünnen Blechen, ohne daß es dazu spezieller Fassungselemente bedarf, etwa kleiner zylindrischer Zusatzfassungen.In an embodiment, the invention provides that a plurality of holes are made in a jewelry sheet, the diameter of which is slightly smaller than the outside diameter of the stones to be grasped, these are then driven together into the holes by means of a press ram and the free upper regions of the outer contour are following be rubbed. This means that a large number of gemstones can be grasped by machine, in particular in thin sheet metal, without the need for special socket elements, such as small cylindrical additional frames.
In Ausgestaltung sieht die Erfindung vor, daß Edelsteine unterschiedlicher Schliffarten, wie beispielsweise Brillant, Baguette, Navette und Carré in die Schmuckmetalle eingepreßt und nachfolgend verrieben werden.In an embodiment, the invention provides that gemstones of different types of cut, such as, for example, brilliant, baguette, navette and carré, are pressed into the jewelry metals and then triturated.
Die Erfindung sieht auch eine Vorrichtung zur Lösung der Aufgabe vor, die sich dadurch auszeichnet, daß sie als eine Auflage für das mit einer Bohrung versehene Schmuckmetall gebildet ist, mit einem dieser Auflage gegenüberliegenden Preßstempel.The invention also provides a device for solving the problem, which is characterized in that it is formed as a support for the jewelry metal provided with a bore, with a press ram opposite this support.
Um ein möglichst gleichmäßiges Eindrücken und damit eine genaue exakte, ebene Fassung des jeweiligen Schmuckstückes zu erreichen sieht die Erfindung in Ausgestaltung vor, daß die ebene Preßstempelfläche, die sich an der Tafel des zu verpressenden Edelsteines anlegt, größer ist, als der größte Außendurchmesser des Schmucksteines.In order to achieve as even a pressing as possible and thus an exact, exact, level setting of the respective piece of jewelry, the invention provides in an embodiment that the flat punch surface that bears against the table of the gem to be pressed is larger than the largest outside diameter of the gem .
Mit dieser Gestaltung läßt sich zusätzlich erreichen, daß der Preßstempel sich bei dem Einpressen auf dem Schmuckmetall abstützt, so daß dessen Eindrücktiefe genau definierbar ist etwa in der Weise, daß die Tafel des Schmucksteines im gefaßten Zustand später mit der Außenoberfläche des Schmuckmetalles fluchtet.With this design it can also be achieved that the ram is supported during the pressing on the jewelry metal, so that its indentation can be precisely defined, for example, in such a way that the table of the jewelry stone later aligns with the outer surface of the jewelry metal in the set state.
Um eine Mehrzahl von Schmucksteinen in beispielsweise Blechen gleichzeitig fassen zu können, sieht die Erfindung auch vor, daß der Preßstempel zur Verpressung einer Mehrzahl von Schmucksteinen in einem Arbeitshub ausgebildet ist.In order to be able to grasp a plurality of gemstones in sheet metal at the same time, the invention also provides that the press ram is designed for pressing a plurality of gemstones in one working stroke.
Ein Merkmal in Ausgestaltung der Erfindung besteht bei dem gleichzeitigen Fassen einer Mehrzahl von Edelsteinen darin, daß die Vorrichtung eine Auflage mit einer Mehrzahl von Bohrungen aufweist, deren Durchmesser größer ist als der Durchmesser des jeweils zu fassenden Edelsteines.A feature in an embodiment of the invention in the simultaneous setting of a plurality of gemstones is that the device has a support with a plurality of bores, the diameter of which is larger than the diameter of the gemstone to be grasped in each case.
Mit dieser Gestaltung wird erreicht, daß beim Einpressen des Edelsteines in das Edelmetallblech zunächst ein Unterbereich des Edelmetalles durch den Edelstein selbst umgebördelt wird um so den unteren Teil des Fassungsbettes zu bilden. Danach kann dann der Stein von oben angerieben werden.With this design it is achieved that when the gem is pressed into the noble metal sheet, a sub-area of the noble metal is first flanged by the gem itself in order to form the lower part of the frame bed. Then the stone can be rubbed from above.
