Definitions
- the present invention relates to a die for coins or medals, comprising a hardened surface in which a motif is produced.
- a die is known from DE 19741998 Al .
- grey tinting is achieved by making indentations by means of radiation with a laser beam.
- Such indentations are of varying depths, for the purpose of obtaining a more or less dark effect subsequently on the coin.
- Grey tints can be achieved in this way.
- the die costs for such dies are considerable, since, apart from the machining with the laser beam, the conventional techniques for manufacturing the die are still necessary. Two methods are generally used in this case.
- the grey tint obtained by means of a pattern of indentations not only is the grey tint obtained by means of a pattern of indentations, but so is the entire motif, in other words its penpheral boundary is too Furthermore, the indentations are no longer of a greater or lesser depth, but are all produced with substantially the same measurement
- the degree of compactness in other words the number of indentations per unit area, a certain image or grey tint is obtained Owing to the particularly small diameter, lying between 0 1 and 3 ⁇ m, a very sharp image can be obtained.
- the indentations descnbed above, with a depth between 1 and 50 ⁇ m, and preferably a depth of approximately 10 ⁇ m, can be produced in a manner known in the pnor art
- the indentations are preferably produced by means of laser technology This means that it is possible to provide a very large number of indentations on a very small surface area. For instance, it is possible to make between 40 and 1,600 indentations per linear inch (2 54 cm) If the laser compnses a CNC-controlled laser, it is possible to control the latter in a simple manner by a central processing unit such as a computer
- the desired picture can be stored and converted into a pixel image
- the indentations in the die are all of the same depth, and a certain image is obtained through vanation of the concentration of indentations
- the picture in the computer can be obtained by scanning a photograph or the like, combined with possibly further processing of this picture It is, of course, also possible to generate the picture in an entirely artificial manner on a computer or the like
- the generated picture can be converted into an indentations structure by means of a relatively simple programme Through the use of laser technology, it is possible to make indentations even in hardened surfaces, with the result that it is possible to harden the die beforehand.
- the cost of the die can be reduced considerably by carrying out these steps in advance.
- the pattern according to the present invention is particularly wear-resistant, unlike lacquer coatings.
- the wear resistance depends on the height of the projecting parts which constitute the mirror image of the indentations in the die.
- the surface of the die for coins or medals can be comb-like.
- it is provided with a series of adjacent ridges, which are always provided with a different pattern, i.e. a different image can be obtained when light is incident upon it from different visual angles.
- a security feature can be provided.
- certain types of holographic images can be achieved in this way.
- the invention also relates to a method for manufacturing a die for coins or medals, comprising starting from a hardened metallic surface and producing in said surface at least part of a motif by making indentations by laser technology, all indentations having substantially the same height and diameter, and a full motif being applied to a surface part solely by a series of indentations.
- the invention further relates to a coin/medal, in which said series of elevations in certain areas comprise 40 - 1,600 projecting parts per linear inch (2.54 cm).
- Fig. 1 shows very diagrammatically the production of a die according to the invention
- Fig. 2 shows the use of a die according to the invention
- Fig. 3 shows in perspective a coin or token produced with the die according to Fig. 2;
- Fig. 4 shows section IV-IV from Fig. 3.
- a die blank or die slug is indicated by 1.
- the die blank has a hardened die surface that is otherwise completely finished. However, no pattern is yet present in this die surface. All that is achieved in the manner shown diagrammatically in Fig. 1.
- An image 8, such as a photograph, is placed in a scanner 7
- the signal coming from the scanner is fed to a central processor such as a computer 5.
- This image can be read off screen 6, and corrections can be made in this picture or further details added to it with the aid of means not shown, such as a mouse and keyboard.
- the picture thus generated is fed to a control unit 4 of a CNC machine, which controls a laser head 3.
- indentations are made in the surface of the die blank by means of a laser 3. Such indentations all have substantially the same depth and shape (diameter).
- the depth lies between 1 and 50 ⁇ m, and is preferably approximately 10 ⁇ m.
- the diameter preferably lies between 0.1 and 3 ⁇ m.
- the die blank is made of a steel matenal.
- the number of indentations made depends on the desired image. All this will be explained in greater detail with reference to Fig. 4.
- the die surface can be provided with a further relief structure in the usual manner, for example by milling. This applies in particular to the penpheral edge if, for example, coins or tokens have to be struck.
- Other examples are a combination of a relief structure with a pattern structure, as is obtained according to the present invention. The die thus obtained is used for the production of coins or medals.
- a die unit is shown in a very diagrammatic way in Fig. 2.
- the unit is indicated in its entirety by 11 and is composed of a top die 2 that is produced after the treatment of the die blank descnbed with reference to Fig 1.
- the bottom die is indicated by 12, and a com or token blank is indicated by 13.
- the final coin or token 14 is produced by a stamping action.
- the com or token is shown in detail in Fig. 3, from which it can be seen that a view like a photograph is produced.
- IV-IV indicates a cross-sectional area of a detail, which is clanfied further with reference to Fig. 4. It can be seen from the latter figure that at least a part of the surface of the coin 14 has a structure with projecting parts 16.
- the projecting parts 16 correspond to the indentations made earlier m the die blank 1 by means of the laser unit 3
- the density of the projecting parts 16 relative to the base 17 determines the tint. Images can be produced in this way. If more raised parts are present, a lighter tint will be obtained.
- Fig. 4 that all raised parts are of substantially the same height. Only the density of the raised parts determines the tint. In fact, this is a case of a relief with two levels, namely base level 17 and the top side of each of the raised parts. It will be understood that the wear resistance of such raised parts is many times greater than that of lacquers, and that the effect obtained is
