Abstract

Podstata vynálezu spočívá v tom, že v elektronevodivom puzdre je uložená pevne elektronevodivá šablona zasahujúca svojou činnou častou před činnú plochu elektrovodivej časti.The essence of the invention lies in the fact that an electrically non-conductive template is firmly placed in an electrically non-conductive housing, its active part extending in front of the active surface of the electrically conductive part.

Description

Vynález sa týká riešenia nástroja pre elektrochemické značkovanie, najmá pre vytváranie farebne odlišných značiek na kovových povrchoch súčiastok.The invention relates to a solution for an electrochemical marking tool, in particular for producing color-coded markings on metal surfaces of parts.

Elektrochemické povrchové značkovanie pomocou šablon s výrezmi v tvare značiek sa v súčasnosti vykonává přiložením šablony na značený povrch nanesením elektrolytu priamo, alebo prostredníctvom posiča do výrezov šablony a následným přitlačením činnej plochy nástroja na povrch šablony. Sú známe aj nástroje, u ktorých je časť šablony pevne, alebo tesne spojená s činnou plochou nástroja a značkovanie sa vykonává namáčaním šablony v elektrolyte a následným pečiatkovaním na posobenia elektrického prúdu. Pri malej velkosti znakov a tenkej hrúbke čiar sú tieto sposoby nespolahlivé, lebo sa nedá zaistiť pri opakovanom značkovaní zatečenie elektrolytu do všetkých výrezov. Výřezy šablony sa zle čistia od elektrochemických reakčných produktov a nie je možné bez poškodenia nástroja obnovovat jeho činnú plochu, z ktoré pri značkovaní striedavým elektrickým prúdom, ubýva.Electrochemical surface marking using stencil-shaped templates is currently accomplished by applying the stencil to the labeled surface by applying electrolyte directly or through a slider to the stencil slots and then pressing the tool's active surface onto the stencil surface. Tools are also known in which a portion of the template is firmly or closely connected to the active surface of the tool and the marking is performed by dipping the template in the electrolyte and then stamping it to energize the current. Due to the small size of the characters and the thin line thickness, these methods are unreliable, since the leakage of the electrolyte into all cut-outs cannot be ensured by repeated marking. The template cut-outs are poorly cleaned from electrochemical reaction products and it is not possible to restore the active surface from which the AC-marking is lost without damaging the tool.

Vyššie uvedené nedostatky zmierňuje a technický problém rieši nástroj pre elektrochemické značkovanie podlá vynálezu, ktorého podstatou je, že v elektronevodivom puzdre je uložená pevne elektronevodivá šablona zasahujúca svojou činnou častou před činnú plochu elektrovodivej časti. Do podstaty vynálezu patří aj to, že činná časť elektronevodivej šablony je před činnou plochou elektrovodivej časti uložená odpružené vo vzdialenosti od 0,1 do 5 mm.The above-mentioned drawbacks are alleviated and the technical problem is solved by the electrochemical marking tool according to the invention, which is based on the fact that the electrically conductive sleeve is embedded in a solid electro-conductive template extending with its active part in front of the active surface of the electroconductive part. It is also an object of the invention that the active portion of the electro-conductive template is spring-loaded at a distance of 0.1 to 5 mm in front of the active surface of the electroconductive portion.

Nástrojom pre elektrochemické povrchové značkovanie sa docieli zvýšenie spolehlivosti pri vytváraní menších a tenších značiek, zjednodušenie čistenia šablony, možnost širšieho využívania striedavého elektrického prúdu pre značkovanie a jednoduchej obnovy činnej plochy nástroja.The electrochemical surface marking tool will increase the reliability in creating smaller and thinner marks, simplify the template cleaning, the possibility of wider use of the alternating current for marking and easy tool surface renewal.

Na pripojenom výkrese je znázorněné příkladné riešenie nástroja podlá vynálezu v řeze.The accompanying drawing shows an exemplary embodiment of a tool according to the invention in cross-section.

Nástroj pre elektrochemické povrchové značkovanie pozostáva z elektrovodivej časti 2 v tvare hranola ukončenej činnou plochou 21. Elektrovodivá časť 2 je posuvné a tesne uložená v elektronevodivom puzdre 4. Elektronevodivá šablona 3 pozostáva z fólie a má tvar L. Jedno rameno elektronevodivej šablony 3 je zasunuté do drážky 1 vytvorenej v jednej stene elektronevodivého puzdra 4 a je zaistené upevňovacou skrutkou 6. Druhé rameno elektronevidovej šablony 3, v ktorom sú vytvořené výřezy, tvoří jej činnú časť 31 a zasahuje šikmo před činnú plochu 21 elektrovodivej časti 2. Najváčšia vzdialenosť pružnej činnej časti 31 elektronevodivej šablony 3 od činnej plochy 21 elektrovodivej časti 2 je 5 mm a je pružná.The electrochemical surface marking tool consists of a prism-shaped electrically conductive part 2 terminated with an active surface 21. The electrically conductive part 2 is slidable and tightly housed in the electro-conductive housing 4. The electro-conductive template 3 consists of an L-shaped foil. groove 1 formed in one wall of the electrically conductive housing 4 and is secured by a fastening screw 6. The second leg of the electrodevide template 3, in which the slots are formed, forms its active part 31 and extends obliquely in front of the active surface 21 of the conductive part 2. The electrically conductive template 3 from the active surface 21 of the conductive part 2 is 5 mm and is flexible.

Funkcia nástroja pre elektrochemické povrchové značkovanie je následovně: Činná časť 31 elektronevodivej šablony 3 a činná plocha 21 elektrovodivej časti 2 sa namočí do elektrolytu, ktorý sa zadrží jednak vo výrezoch činnej časti 31 elektronevodivej šablony 3 a jednak na činnej ploché 21 elektrovodivej časti 2 a prilahlým povrchom. Pri vlastnom značkovaní sa přitlačí činná časť 31 elektronevodivej šablony 3 na značkovaný povrch súčiastky, čím sa táto přitlačí na činnú plochu 21 elektrovodivej časti 2 a tým sa zaistí spolehlivé zaplnenie výrezov činnej časti 31 elektronevodivej šablony 3 elektrolytom. Potom sa zapne elektrický prúd a vykoná sa vlastně značkovanie.The function of the electrochemical surface marking tool is as follows: The active portion 31 of the electroconductive template 3 and the active surface 21 of the electroconductive portion 2 are soaked in an electrolyte which is retained both in the slots of the active portion 31 of the electroconductive template 3 and surface. During self-marking, the active portion 31 of the electroconductive template 3 is pressed onto the surface of the component to be marked, thereby pressing it onto the active surface 21 of the electroconductive portion 2 and thereby reliably filling the cut-outs of the active portion 31 of the electroconductive template 3 with electrolyte. The electric current is then switched on and the marking is actually carried out.

Činnú časť 31 elektronevodivej šablóny 3 je možné tvarovat i do zložitejších tvarov, ako například do tvaru U s upevněním oboch koncov činnej plochy 31 elektronevodivej šablóny 3. Výhody nástroja sa prejavia vždy, ak elektrolyt pri nanášaní nástroja má možnost vniknúť medzi činnú časť 31 elektronevodivej šablóny 3 a činnú plochu 21 elektrovodivej časti 2.The active portion 31 of the electro-conductive template 3 can also be shaped into more complex shapes, such as a U-shape, with both ends of the active surface 31 of the electrically conductive template 3 fixed. 3 and the active surface 21 of the conductive part 2.
