Abstract

Inventia se refera la domeniul prelucrarii electrochimice dimensionale, in particular la un electrod-scula si un procedeu de perforare electrochimicaa orificiilor si poate fi utilizata in industria constructoare de masini. Electrodul-scula include o portiune de lucru (11) din material magnetic moale, ce reprezinta o sfera cava cu orificii (12), pe suprafata ei externa sunt executati ghimpi izolatori (17), in interiorul portiunii de lucru este amplasat un ecran mobil (15) in forma de semisferacu posibilitatea de deplasare, totodata de ecranul (15) este fixat un magnet (14) cu un orificiu central, portiunea de lucru este conectata la catod printr-un conductor electric, iar prin intermediulunui racord cu un tub flexibil (13) pentru evacuarea electrolitului. Raportul dintre diametrul orificiului magnetului catre diametrul orificiilor de pe suprafata de lucru este de 1,0 : 1,0…2,5. Procedeul de perforare electrochimica a orificiilor consta in amplasarea piesei intr-o camera inchisa, conectarea piesei la polul pozitiv al sursei de curent, iar a electrodului-scula, definit in revendicarea 1, la polul negativ, electrolitul este debitat prin canalul piesei spre portiunea de lucru, iar electrolitul uzat se evacueaza prin orificiile portiunii de lucru, orificiul central al magnetuluisi tubul flexibil, totodata pozitia ecranului mobil se schimba cu ajutorul unui magnet amplasat in exteriorul camerei pentru obtinerea traiectoriei necesare a canalului.The invention relates to the field of dimensional electrochemical processing, in particular to an electrode-tool and a process for electrochemical hole drilling and can be used in the machine building industry. The tool electrode includes a working portion (11) of soft magnetic material, which represents a hollow sphere with holes (12), on its external surface insulating spikes (17) are executed, inside a working screen is placed a movable screen ( 15) in the form of a hemisphere the possibility of movement, at the same time the screen (15) is fixed a magnet (14) with a central hole, the working portion is connected to the cathode by an electrical conductor, and through a connection with a flexible tube ( 13) for electrolyte evacuation. The ratio of the diameter of the magnet hole to the diameter of the holes on the work surface is 1.0: 1.0 ... 2.5. The process of electrochemical perforation of the holes consists in placing the part in a closed chamber, connecting the part to the positive pole of the current source, and of the tool electrode, defined in claim 1, to the negative pole, the electrolyte is cut through the part channel to the portion of the source. work, and the spent electrolyte is evacuated through the holes of the working portion, the central hole of the magnetuluisa flexible tube, at the same time the position of the mobile screen is changed with the help of a magnet located outside the chamber to obtain the necessary channel trajectory.
