Description

Vynález sa týká spůsobu zhotovovania ohybného pracovného nástroja na elektrochemické vytváranie znakov.The invention relates to a method of making a flexible working tool for electrochemical character generation.

Elektrochemické vytváranie znakov, či už na hotových výrobkoch, polotovaroch, alebo materiáloch sa v technologickej praxi vykonává v niekotko variantách. V prevažnej miere sa jedná o povrchové znaky to je, vytvořený znak zasahuje len povrchová vrstvu materiálu. Elektrochemický sposob označovanía je vysoko produktívny, preto je vhodný pre ozňačovanie najmá hromadné vyrábaných výrobkov.Electrochemical character creation, whether on finished products, semi-finished products or materials, is performed in several variants in technological practice. They are mostly surface features, that is, the formed feature only affects the surface layer of the material. The electrochemical labeling process is highly productive, therefore it is suitable for labeling especially bulk products.

Doteraz používané spósoby elektrochemického označovanía sa vykonávajú cez šablony z elektroizolačnej hmoty s papierovou, alebo textilnou páskou navlhčenou elektrolytom. Tento spůsob označovanía dovoluje označovat len rovné povrchy s málo výrazným znakom, pretože malé množstvo elektrolytu v tenkej páske nie je schopné vytvořit výraznější znak. Nevýhodou týchto sposobov je malá životnost' šablon a prácne ich zhotovovanie. Sú známe aj elektroizolačné vrstvy nástrojov pre elektrochemické obrábaníe do ktorých sa vytváranie znakov vykonává známými mechanickými spůsobmi velmi obťažne, pretože sa jedná o velmi tenké ohybné pracovně nástroje.The electrochemical marking methods used hitherto are carried out by means of electro-insulating material templates with a paper or textile tape moistened with an electrolyte. This method of marking makes it possible to mark only flat surfaces with little prominent feature, since a small amount of electrolyte in the thin tape is not capable of producing a more prominent feature. The disadvantage of these methods is the low lifetime of the templates and the laborious manufacture thereof. Electro-insulating layers of tools for electrochemical machining are also known, in which the character formation is very difficult to perform by known mechanical means, since they are very thin flexible working tools.

Vyššie uvedené nevýhody podstatné zmierňuje spůsob zhotovovania ohybného pracovného nástroja na elektrochemické vytváranie znakov podía vynálezu, ktorého podstatou je, že najprv sa zo strany elektrovodivej vrstvy mechanicky vytvoria znaky do híbky vSčšej ako je požadovaná hrúbka elektroizolačnej vrstvy. Potom sa elektrovodivá vrstva spájkovaním upevní na nosnú fóliu. Nakoniec sa mechanicky opracuje elektroizolačná vrstva na hrůbku od 0,2 do 0,3 mm.The abovementioned disadvantages are substantially reduced by the method of making a flexible working tool for the electrochemical generation of features according to the invention, which essentially consists in that the features of the electro-conductive layer are first mechanically generated to a depth greater than the required thickness of the electro-insulating layer. Then, the electroconductive layer is brazed to the carrier film. Finally, the electrical insulating layer is mechanically machined to a thickness of 0.2 to 0.3 mm.

Spósobom zhotovovania ohybného pracovného nástroja na elektrochemické vytváranie znakov sa docieli zhotovenie výrazného znaku 1'ubovol'ného tvaru a velkosti a to i na různé tvarové povrchy obrobkov. Výhodou vynálezu je aj to, že umožňuje zhotovovanie znakov na velké obrobky.By producing a flexible working tool for electrochemical character generation, a distinctive feature 1 'of arbitrary shape and size is achieved, even on different shaped workpiece surfaces. It is also an advantage of the invention that it enables the production of features on large workpieces.

Na pripojenom výkrese je znázorněné příkladné riešenie sposobu zhotovovania ohybného pracovného nástroja na elektrochemické vytváranie znakov, kde na obr. 1 je nakreslená doska s elektronevodivou a elektrovodivou vrstvou v řeze, na obr. 2 je nakreslená uvedená doska po mechanickom zhotovení znakov v řeze, na obr. 3 je nakreslená doska prispájkovaná na nosnú fóliu v řeze a na obr. 4 je pracovný nástroj po dohotovení v řeze.In the accompanying drawing, an exemplary embodiment of a method for producing a flexible working tool for electrochemical character generation is shown. 1 is a cross-sectional view of a board with an electrically conductive and an electroconductive layer; 2 is a cross-sectional view of the plate after mechanical production of the features; FIG. 3 is a sectional view of a drawing plate soldered to a carrier film; and FIG. 4 is a sectional view of the working tool after finishing.

Spósob zhotovovania ohybného pracovného nástroja na elektrochemické vytváranie znakov je nasledovný: Do kuprextitovej došky o hrúbke 1 mm, ktorá má elektrovodivú vrstvu 2 hrubú 0,02 mm sa zo strany elektrovodivej vrstvy 2 vygravírujú znaky 4 do hlbky 0,5 mm. Takto zhotovená doska sa prispájkuje elektrovodivou vrstvou 2 na nosnú fóliu 1 o hrúbke 0,1 mm. Potom sa prebrúsi elektroizolačná vrstva 3 na hrůbku 0,2 mm, čím sa vygravírované znaky 4 otvoria.The method of making a flexible working tool for electrochemical character generation is as follows: In a 1 mm thick crepextite that has a 0.02 mm thick conductive layer 2, the characters 4 are engraved on the side of the conductive layer 2 to a depth of 0.5 mm. The plate thus produced is soldered by an electroconductive layer 2 to a carrier film 1 having a thickness of 0.1 mm. The electro-insulating layer 3 is then ground to a depth of 0.2 mm, thereby opening the engraved features 4.

Ohybný pracovný nástroj sa predtvaruje podía tvarovej plochy, na ktorej má byť zhotovený znak 4 a může sa začat vykonávat vlastná operácia elektrochemického značenia.The flexible working tool is preformed according to the shape area on which the feature 4 is to be produced and the actual electrochemical marking operation can be performed.
