Description

State of the art

Goldsmiths usually work with old and proven craft techniques. These techniques are used in the manufacture of unique pieces, to do so include forging, sawing, soldering, driving, pulling, rolling, filing etc.

To make a ring band, the goldsmith first saws a strip of down a sheet of silver or gold and work it with the above Techniques until he has the right strength, width and length. Then the Sheet metal strips bent or forged around a ring bar and then soldered.

Goldsmiths rarely work with casting techniques. This is because that the production of a mold for one-off production is currently still too is "time consuming" and "inaccurate". This in turn is due to the fact that the Manufacturing, a casting mold material is wax. There are soft ones Wax varieties that are processed by hand warmth alone or by slight pressure is bent = not dimensionally stable, on the other hand hard, brittle Wax types are dimensionally stable but break easily, so it's a problem to manufacture individual rings using conventional casting techniques.

Goldsmiths lose the time and accuracy they gained from the old ones Achieve crafting techniques with no difficulty, consequently this way On the other hand, not often worked for the serial production of industrial jewelry or Goldsmith series is only cast. Here is a prototype made of metal, with old handicrafts, which is then manufactured in a foundry Silicone casting is reproduced.

In these silicone casts (up to a hundred or more identical hollow forms of the prototype are in such a silicone cast) wax is now injected. After that, the Wax rings that are now strung together, like a string of pearls, embedded, the wax burned out and the resulting cavity with gold or silver poured out. Then the rings are freed from the investment, from Casting channel separated and worked out.

Description of the invention

The stated invention is based on the problem of a system for time-saving and exact production of an individual plastic or Show wax ring band for later casting.

This problem is solved with those listed in the independent claims Features resolved.

1. Ringinnendurchmesser,

2. Ringaussendurchmesser und

3. Ringbreite

The system allows three parameters to be combined, which uniquely describe a ring. These parameters are:

1. inner ring diameter,

2. Ring outer diameter and

3. Ring width

With the invention it is achieved that by the combination of base plate, Threaded rod, cylinders, sleeve and ring width determiner individual ring rails can be manufactured for later casting, which can be produced quickly and precisely can be reproduced as often as required.

1. Keine Lötstelle => (auf gegossenen Ringschienen kann mit einem höher schmelzenden Lot weiter gearbeitet werden, da keine Lötstelle an der Ringschiene ist. Gegossene Ringe haben keine Lotstelle, können somit problemlos geweitet oder verkleinert werden => keine "Sollbruchstelle".

2. Ein Wachs- bzw. Kunststoffring lässt sich so lange bearbeiten bis er "gefällt", bevor er gegossen wird.

3. Wenig Metallverlust da Arbeitsgänge wie z. B. sägen oder feilen weitestgehend wegfallen, diese können nämlich schon größten Teils in Wachs bzw. Kunststoff erledigt werden.

4. Wachs bzw. Kunststoffringe lassen sich leicht bearbeiten = weicheres Material als Metall = Sägen, Feilen, und Schleifkörper halten länger.

5. Auf Wachs bzw. Kunststoffringe kann mit Wachs modelliert werden = individuelle und schnelle Formgebung.

Using the cast for single-piece production makes sense for the following reasons:

1. No solder joint => (on cast ring rails you can continue to work with a higher melting solder, since there is no solder joint on the ring rail. Cast rings have no solder joint, can therefore be easily expanded or reduced => no "predetermined breaking point".

2. A wax or plastic ring can be worked on until it "falls" before it is cast.

3. Little metal loss because operations such. B. saw or file as far as possible, because they can be largely done in wax or plastic.

4. Wax or plastic rings are easy to work = softer material than metal = sawing, filing, and grinding tools last longer.

5. Wax can be modeled on wax or plastic rings = individual and quick shaping.

Thus, the molding is made by this invention for the user to manufacture Individual castings more interesting, since he is now without solder, without metal loss, without filing, sawing, forging, rolling, pulling, bending etc. and with little time required an individual, exact and reproducible wax or plastic ring band is able to reach, on which he then without "manual limits" by modeling with wax, design every conceivable shape individually and for as long can change until he likes it.

A further embodiment of the invention are the subject of the dependent claims. An advantageous equipment of the invention is specified in claim 2. The development according to claim 2 enables the user to produce eccentric ring rails instead of simple, evenly round ring rails.
Another advantageous feature of the invention is specified in claim 3 or 5. The development according to claim 3 or 5 enables the user to produce rings with different shapes.
Another advantageous equipment of the invention is given in claim 7. The development according to claim 7 enables the user to continuously increase or decrease the ring width by the ring width determiner having an adjusting screw or other adjusting means in order to be able to individually adjust its width (or height).
The development of the invention according to claim 8 gives the user the opportunity to save metal by gluing the cavity templates onto the cylinder or sleeve, which determines the inner diameter of the ring.
The development of the invention according to claim 9 gives the user the ability to easily and quickly design the surface of the ring by gluing the surface templates onto the sleeve, which determines the outer diameter of the ring.
The development of the invention according to claim 10 provides the user with a ring casting system that is easy to transport and space-saving.

Description of the embodiments

A first exemplary embodiment of the invention is illustrated in FIGS. 1 to 9 explained.

The system essentially comprises a base support, consisting of base plate 1 with threaded rod 4, a cylinder 5 for each standard ring size with a matching outer sleeve 7, and several ring width determiners in different widths.
First you screw the threaded rod 4 into the threaded hole 3 of the base plate 1 (Figures 1, 2, 3 and 6). Now the ring size of the customer is determined using the "ring game". The cylinder 6 suitable for the ring size of the customer is now selected, pushed out of its sleeve and set aside. The determination of the inner ring diameter has been completed.

From a table, the larger the customer's ring size can be, a larger one Cylinder 5 are selected, which determines the outer ring diameter.

Now the just selected cylinder 5 with its sleeve 7 on the threaded rod 4th inserted (Figure 7).

Now, according to FIG. 8, the smaller cylinder 6, which has the inside diameter of the ring is determined, also be placed on the threaded rod 4.

After this has been done, according to FIG. 9, a selection of Ring width determiners 8 of different widths can be taken from the desired one and pushed into the groove 2 of the base plate 1. Now the sleeve 7 of the Larger cylinder 5 raised and the ring width determiner 8 in the groove 2 further pushed up to the larger cylinder 6. Then the sleeve 7 again pushed down until it rests on the ring width determiner 8. Now he can thus created cavity 9 can be filled with wax or plastic in any order to get the desired ring band.

After cooling or polishing the wax or plastic, the The equipment can be taken apart and the individual ring band is ready on which you can continue to work comfortably.

A further exemplary embodiment of the invention is illustrated in FIGS. 10-15 explained.

The system essentially comprises a base support consisting of base plate 1 with threaded rod 4, a socket set 11, each with a sleeve for each Standard ring size, and several ring width determiners 12 in different Lengths.

First you screw the threaded rod 4 into the threaded bore 3 of the base plate 1 (Figures 11-14).
Now the ring size of the customer is determined using the "ring game".
The desired ring width determiner 12 is then inserted into the bore 10, which is suitable for the customer's ring size, in the base plate 1. The base plate 1 contains a corresponding bore 10 for each ring size. The length of the ring width determiner 12 determines the width of the ring. (Determination of the inner ring diameter and the ring width)

Then a ring width determiner 12 of the same length is inserted into one on the base plate 1 hole 10 located further out. (Determination of the Outer ring diameter)

Now, according to FIG. 15, the socket set 11, consisting of a plurality of the cylindrical sleeves, placed over the threaded rod 4 and on the base plate 1 pushed, thereby the sleeves 13 and 14, the inside and Determine the outer diameter of the ring to be produced, slide it out and in such a way that a cavity 15 is created, which exactly the desired ring describes. Now the resulting cavity 15 can be made with wax or Plastic be filled up.

After cooling or polishing the wax or plastic, the The equipment can be taken apart and the individual ring band is ready on which you can continue to work comfortably.
