Description

Vynález sa týká přívodu elektrického prúdu najma pri elektrochemickom obrábaní viacerých plechových obrobkov rovnakej hrábky.The invention relates to the supply of electric current, in particular in the electrochemical machining of several sheet metal workpieces of the same rake.

Pri elektrochemickom obrábaní tenkých obrobkov ako sú například neprofilované plechy, je technickým problémom zaistenie spolehlivého upnutia týchto obrobkov a súčasne ich rýchleho pripojenia na zdroj elektrického prúdu.In the electrochemical machining of thin workpieces, such as non-profiled sheets, the technical problem is to ensure a reliable clamping of these workpieces and at the same time their fast connection to the power source.

Doteraz sa upnutie tenkých obrobkov uskutočňovalo mechanicky, elektromagnetickým upínacím zariadením, pri ktorom sa pracovný elektrolyt dostával i na povrch upínacieho zariadenia, a to i medzi upínací povrch a obrobok, čím v důsledku elektrolytických dejov dochádzalo k poškodzovaniu povrchu upínacieho zariadenia.To date, clamping of thin workpieces has been performed mechanically, by an electromagnetic clamping device, in which the working electrolyte has also reached the surface of the clamping device, even between the clamping surface and the workpiece, thereby damaging the surface of the clamping device due to electrolytic events.

Tento nedostatok je možné odstrániť použitím ochrannej fólie umiestnenej medzi upínacím povrchom zariadenia a obrobkom. Pri použití ochrannej fólie z umelej hmoty, alebo kovověj odolávajúcej elektrochemickým účinkom vznikajú problémy s prívodom elektrického prúdu na obrobok, pretože pri doteraz používaných sposoboch uchytenia prívodnej podložky na obrobok, napr. upínkami je pomalé, technicky náročnejšie a může dojsť k poškodeniu ochrannej fólie. Tieto problémy sa ešte stupňujú so zvyšováním počtu súčasne obrábaných súčiastok.This drawback can be overcome by using a protective foil located between the clamping surface of the device and the workpiece. The use of a protective foil made of plastic or of metal resistant to electrochemical effects causes problems with the supply of electric current to the workpiece. clamps are slow, technically demanding and can damage the protective film. These problems are exacerbated by the increase in the number of parts machined simultaneously.

Uvedený technický problém rieši a nevýhody zmierňuje přívod elektrického prúdu na tenký obrobok najma pri obrábaní viacerých plechových obrobkov rovnakej hrůbky podlá tohoto vynálezu, ktorého podstatou je, že na povrchu obrobkov nestýkajúcom sa s ochrannou fóliou je uložená feromagnetická, elektricky vodivá príložka připojená na zdroj jednosměrného elektrického prúdu.This technical problem solves and disadvantages alleviates the supply of electric current to the thin workpiece, in particular when machining multiple sheet metal workpieces of the same depth according to the invention, which is based on a non-protective film non-contacting workpiece surface attached to a DC source. current.

Přívod elektrického prúdu na tenké obrobky je příkladné znázorněný na pripojenom výkrese, kde obr. 1 je nárys a obr. 2 podorys zariadenia.The power supply to the thin workpieces is exemplified in the attached drawing, where FIG. 1 is a front view and FIG. 2 is a plan view of the device.

Přívod elektrického prúdu na sedem plechových obrobkov rovnakej hrůbky je převedený následovně. Tenké plechové obrobky 2 sú umiestnené na povrchu elektromagnetického upínacieho stolíka 3, ktorého upínací povrch je chráněný tenkou ochrannou fóliou 4. Na povrchu obrobkov 2 nestýkajúcom sa s ochrannou fóliou 4 je uložená feromagnetická, elektricky vodivá príložka 5, připojená na kladný pól zdroje jednosměrného elektrického prúdu 7.The power supply to the seven sheet metal workpieces of the same depth is converted as follows. Thin sheet workpieces 2 are located on the surface of the electromagnetic clamping table 3, the clamping surface of which is protected by a thin protective film 4. On the surface of the workpieces 2 not contacting the protective film 4 is a ferromagnetic electrically conductive shim 5 connected to the positive pole of the direct current source. 7th

Pri uvedení elektromagnetického upínacieho stolíka 3 do činnosti, sa působením magnetického póla tak na tenké obrobky, ako i na feromagnetickú príložku zaistí rovnoměrná, čo do velkosti opakovatelná upínacia sila, pridržujúca tenké obrobky 2 súčasne s feromagnetickou elektricky vodivou príložkou 5, ktorá zaisťuje přívod prúdu zo zdroja jednosměrného elektrického prúdu 7 rovnoměrně na všetky tenké obrobky 2.Upon actuation of the electromagnetic clamping table 3, a uniform, large repeatable clamping force holding the thin workpieces 2 simultaneously with the ferromagnetic electrically conductive clamp 5 is provided by the magnetic pole to both the thin workpieces and the ferromagnetic clamp 5 to provide power to the workpiece. a source of direct current 7 evenly across all thin workpieces 2.
