Abstract

Inventia se refera la domeniul prelucrarii electrochimice dimensionale, in particular la un electrod-scula si un procedeu de perforare electrochimica a orificiilor, poate fi utilizata in industria constructoare de masini la confectionarea imbinarilor articulate. Electrodul-scula, conform inventiei, include un corp cav executat in forma de T, a carui parte dielectrica este jumatatea superioara a electrodului, de care este fixat organul cu o suprafata de lucru electroconductoare executata dintr-un material elastic, de exemplu cauciuc metalizat, avand sectoare cu elasticitate diferita si fiind dotata cu ghimpi izolatori dielectrici, la capatul inferior al suprafetei de lucru este fixata o parte din material dielectric, iar in interiorul corpului, in partea centrala este instalata o despartitura transversala cu orificii pentru fixarea canalului de debitare a electrolitului, care este executat in partea lui inferioara in forma de silfon flexibil, corpul in partea superioara este dotat cu un racord pentru debitarea unui gaz in cavitatea interna. Procedeul, conform inventiei, include executarea pe suprafata unei piese metalice conectate la polul pozitiv al sursei de curent prin metoda dizolvarii anodice, a unei cavitati conice, apoi perforarea piesei pe axa de simetrie a cavitatii conice cu formarea unui canal cilindric si prelucrarea electrochimica dimensionala a canalului cu electrodul-scula mentionat in revendicarea 1, cu formarea unei cavitati necesare datorita presiunii din cavitatea corpului, care modifica dimensiunea si forma suprafetei de lucru, depunerea catodica pe suprafata de lucru a electrodului-scula a unui strat de metal cu inlaturarea ulterioara a suprafetei de lucru initiale prin tratare chimica, umplerea cavitatii electrodului cu masa plastica sau metal lichid, iar in spatiul dintre piesa si suprafata cuprinsa se introduce un agent antifrictiune.The invention relates to the field of dimensional electrochemical processing, in particular to an electrode-tool and a process of electrochemical perforation of the holes, which can be used in the machine building industry when making articulated joints. The tool electrode, according to the invention, includes a T-shaped hollow body, the dielectric part of which is the upper half of the electrode, from which the body is fixed with an electroconductive work surface made of an elastic material, for example metallic rubber, having sectors with different elasticity and being equipped with dielectric insulating spikes, at the lower end of the work surface is fixed a part of dielectric material, and inside the body, in the central part is installed a transverse partition with holes for fixing the electrolyte cutting channel. , which is executed in its lower part in the form of a flexible whistle, the body in the upper part is equipped with a connection for the flow of gas in the internal cavity. The process, according to the invention, includes the execution on the surface of a metal piece connected to the positive pole of the current source by the method of anodic dissolution, of a conical cavity, then perforating the piece on the axis of symmetry of the conical cavity with the formation of a cylindrical channel and the dimensional electrochemical processing of the tool electrode channel mentioned in claim 1, with the formation of a necessary cavity due to the pressure in the body cavity, which changes the size and shape of the working surface, the cathodic deposition on the working surface of the tool electrode of a metal layer with subsequent removal of the surface initial work by chemical treatment, filling the electrode cavity with plastic or liquid metal, and in the space between the piece and the surface covered, an antifriction agent is introduced.
