Oblasť technikyTechnical field
Vynález sa dotýka dvojdieIného polotovaru pre mince, medaile, cenné známky, hracie známky a podobné, pozostávajúci z vnútorného kotúča z prvého kovu alebo zliatiny kovu, ktorý je zalisovaný do stredového otvory vonkajšieho krúžku z druhého kovu alebo druhej zliatiny kovu.The invention relates to a two-piece blank for coins, medals, tokens, tokens and the like, consisting of an inner disk of a first metal or metal alloy which is pressed into the central holes of the outer ring of the second metal or second metal alloy.
Doterajší stav technikyBACKGROUND OF THE INVENTION
V minulosti boli mince vyrábané hlavne z jedného kusu z masívneho kovu jednotného s1 oženía. Okrem toho sa mince vyrábali i z rôznych kovov a zliatin kovov. Jedná sa pri tom prevažne o vrstvené sendvičové materiály, ktoré sa vyrábajú napríklad plátovaním válcovaním oceľového jadra s obojstranným povlakom z mosadze. Skôr sa pre výrobu mincí používali stále častejšie aj také spojenia materiálu, ktoré pozostávali z vnútorného kotúča z jedného kovu, okolo ktorého bol uložený vonkajší krúžok z iného kovu alebo inej zliatiny kovu. Tak napríklad talianská 500 lírová minca pozostáva s do zlata zafarbenej zliatiny medi. Koncentricky okolo tohoto vnútorného kotúča je nalisovaný vonkajší krúžok z namodralo trblietajúcej sa striebrošedej chrómovej ocele. Rýchlobežné raziace stroje podľa dnešnej strojnej techniky, pomocou ktorých sa vyrábajú tieto spojenia materiálov s únosaným nákladom aj v prípade veľkého počtu kusov, vyžadujú pri výrobe zložiek takéhoto koncentrického spojenia materiálu obzvláštnu pozornosť. Sú preto nevyhnutné zvláštné opatrenia, aby sa dosiahlo pri razení spojenie vnútorného kotúča a vonkajšieho krúžka, ktoré by na sebe dobre drža1o.In the past, the coins were mainly made of one piece of solid metal with a single grain. In addition, coins were also made from various metals and metal alloys. These are predominantly laminated sandwich materials, which are produced, for example, by rolling the steel core with a double-sided brass coating. Rather, such material junctions have increasingly been used to produce coins, which consisted of an inner disk of one metal around which an outer ring of another metal or another metal alloy was placed. For example, the Italian 500-liter coin consists of a gold-colored copper alloy. Concentrically around this inner disc is an outer ring made of blue glittering silver-gray chrome steel. High-speed embossing machines according to today's machine technology, by means of which these load-bearing material joints are produced even in the case of a large number of pieces, require special attention in the manufacture of the components of such concentric material joints. Therefore, special precautions are necessary in order to achieve a fitting connection of the inner disc and the outer ring, which would adhere well to each other.
V US-A- 3 499 739 sa navrhuje, aby sa vonkajší krúžok zvolil o niečo hrubší ako vnútorný kotúč. Tým sa má pri lisovaní vonkajší krúžok natlačiť cez hrany vnútorného kotúča, a tým sa má dosiahnúť tvarového styku spojenia kotúča a krúžku. JP-A- 58-3743 obsahuje návrh opatriť vnútorný kotúč alebo alternatívne vonkajší krúžok obvodovou okrajovou drážkou. Pre spojenie sa obe zložky vložia do seba, a pomocou špeciálneho nástroja sa materiál vnútorného kotúča nalisuje do drážky vo vonkajšom krúžku alebo obrátene.It is proposed in US-A-3 499 739 that the outer ring be selected somewhat thicker than the inner disc. As a result, the outer ring is to be pressed over the edges of the inner disc during the pressing, and thus a positive fit of the disc-ring connection is achieved. JP-A- 58-3743 contains a proposal to provide an inner disk or alternatively an outer ring with a peripheral groove. For coupling, the two components are inserted into each other, and by means of a special tool, the material of the inner disc is pressed into a groove in the outer ring or vice versa.
Z EPA-A-0 080 437 je známe, že sa vnútorný okraj, vonkajšieho krúžkuí vytvorí klinovitý a vnútorný kotúč sa opatrí s okrajovým vymačknutým valom. Pri lisovaní môže potom materiál z tohoto valu tiecť cez zúžený vnútorný okraj vonkajšieho krúžku. Súčasne sú na vnútornom okraji vonkajšieho krúžku usporiadané ešte početné vystupujúce zuby, ktoré sa pri razení majú vtlčiť do vnútorného kotúča. Tým sa vylúči možnosť vzájomného pootočenia vonkajšieho krúžku a vnútorného kotúča po zlisovaní.It is known from EPA-A-0 080 437 that the inner edge of the outer ring is wedge-shaped and the inner disc is provided with an edge squeezed roll. In the molding, the material from this wall can then flow through the tapered inner edge of the outer ring. At the same time, a plurality of protruding teeth are also provided on the inner edge of the outer ring, which are to be inserted into the inner disc during shifting. This eliminates the possibility of rotating the outer ring and the inner disc relative to each other after compression.
EP-A-0 160 343 sa chápe tejto myšlienky s veľmi podobne vytvoreným vonkajším krúžkom. IJ mince známej z EP-A-0 280 615 sa do vonkajšieho krúžku zavádza kôpka a potom sa plasticky pretvaruje na vnútorný kotúč. U EP-A- 0 415 892 sa vnútorný okraj vonkajšieho krúžku opatrí prerušovanou obvodovou drážkou, do ktorej potom pri lisovaní tečie materiál vnútorného kotúča.EP-A-0 160 343 understands this idea with a very similarly formed outer ring. An IJ coin known from EP-A-0 280 615 is introduced into the outer ring by a pile and then plastically formed into an inner disc. In EP-A-0 415 892, the inner edge of the outer ring is provided with a discontinuous circumferential groove, into which the material of the inner disc flows during pressing.
Zatiaľ čo sa náuka podľa US-A- 3 499 739 ukázala byť pre praktické použitie nepostačujúca, a náuka podľa vyššie uvedenej JP-A vyžaduje pre spojenie špeciálny nástroj, majú náuky podľa EP-A- 0 080 437, 0 160 343 a 0 415 892 ten nedostatok, že sa vnútornej strane krúžku musí dať komplikovaný geometrický tvar.While teaching according to US-A-3 499 739 has proved to be inadequate for practical use, and teaching according to the above JP-A requires a special tool for connection, they have teaching according to EP-A-0 080 437, 0 160 343 and 0 415 892 the drawback that a complicated geometric shape must be given to the inner side of the ring.
Podstata vynálezuSUMMARY OF THE INVENTION
Nečakane sa teraz ukázalo, že sa pomocou jednoducho vykonateľného a jednoduchého tvarovania vonkajšieho okraja vnútorného kotúča bezpečne zabráni pretočeniu oboch dielov a vypadnutie vnútorného kotúča z vonkajšieho krúžku po lisovaní. K tomu účelu postačí, ak sa vonkajší okraj vnútorného kotúča opatrí vybraniami prebiehajúcimi vo vzájomne šikmo smerujúcom usporiadaní. Tieto vybrania môžu byť vytvorené aj ako špirálová drážka. Tým sa uľahčí tečenie materiálu vonkajšieho dielca do vybrania vnútorného dielca.Unexpectedly, it has now been shown that by simply executing and simple shaping the outer edge of the inner disc, the twisting of both parts and the falling off of the inner disc from the outer ring after pressing are safely prevented. For this purpose, it is sufficient if the outer edge of the inner disk is provided with recesses running in an obliquely directed configuration. These recesses can also be designed as a spiral groove. This facilitates the flow of material of the outer panel into the recess of the inner panel.

Pip-i--ďalšom 'vytvoron í--vynálosú je--to vyrie-šonó--Vaky- že elektrická vodivosť vonkajšieho krúžku a vnútorného kotúča koncentrického mincového spojenia materiálov je veľmi odlišná.The further development of the invention is that the electrical conductivity of the outer ring and the inner disk of the concentric coin bonding of the materials is very different.
To sa najlepšie dosiahne tým, že sa pre elektricky dobre vodi vý diel trickým použije medený mincový materiál so odporom maximálne 25 μ Ω .cm. Pre špec i f i ckým elektricky zle elekvodivý diel sa má zvoli ť chrómová oceľ alebo chromniklová oceľ so špecifickým elektrickým odporom minimálne μ Ω.This is best achieved by using copper coin material with a resistance of not more than 25 μ Ω cm for electrically well conductive tric. For a specific electrically poorly conductive part, chrome steel or chromium-nickel steel with a specific electrical resistance of at least μ Ω should be selected.
cm.cm.
Elektricky horšie vodivý diel môže byť tiež vrstvený spoj z fer i tickej alebo austenitickej ocele.The electrically inferior conductive part can also be a laminated joint of ferrous or austenitic steel.
Tým sa dosiahne nasledujúce = dnešné elektronické skúšobné prístroje pre mince využívajú rôznym spôsobom princíp elektromagnetického vzájomného pôsobenia medzi elektromagnetickými poľami s rôznou frekvenciou a mincovými kov «q»’ . Pri priechode mincí systémom cievok mincových skúšobných prístrojov sa dajú dosiahnúť charakteristické dvojsignály, pokiaľ značne lepšie vodivý diel materiálového spojenia tvorí vonkajší krúžok alebo alternatívne jednotlivý signál s charakteristickou formou krivky, keď značne lepšie vodivý diel tvorí vnútorný kotúč.This achieves the following = today's electronic coin tester uses the principle of electromagnetic interaction between electromagnetic fields at different frequencies and coin coins in different ways. When passing coins through the coil system of coin tester, characteristic double signals can be obtained if the significantly better conductive part of the material connection forms the outer ring or alternatively a single signal with the characteristic form of the curve when the significantly better conductive part forms the inner disc.
