Abstract

Podstatou riešenia je, že na čele oproti upínacieho otvoru sú vytvořené aspoň dva odstupňované strediace otvory, ktoré sú po obvode přerušované.The essence of the solution is that at least two stepped centering holes are formed on the face opposite the clamping hole, which are interrupted along the circumference.

Description

Vynález sa týká riešenia upínacieho kotúča prstencových obrobkov, například na elektroiskrových drotových řezačkách.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamping disc for annular workpieces, for example on electro-spark drill cutters.

Doteraz sa delenie prstencových kotúčov roznych priemerov na rozdielne počty rovnakých dielcov· šikmými rezmi o hrúbke maximálně 0,30 mm vykonává pomocou šablón a opátovným přepínáním rozřezaného prstencového obrobku na stol elektroiskrovej řezačky po každom odrezanom dielci. Nevýhodou tohoto postupu sú velmi dlhé medzioperačné časy a vznik častých nepodarkov z dóvodov uvolneniá vnútorného pnutia prstencových obrobkov.Until now, the division of the annular discs of different diameters into different numbers of equal parts by oblique cuts with a maximum thickness of 0.30 mm is performed by means of stencils and repeated switching of the cut annular workpiece on the table of the electro-spark cutter after each cut piece. The disadvantage of this process is the very long inter-operative times and the occurrence of frequent failures due to the releasing of the internal tension of the annular workpieces.

Vyššie uvedené nedostatky odstraňuje a technický problém rieši upínací kotúč prstencových obrobkov, najma na elektroiskrových drotových řezačkách pódia vynálezu, ktorého podstatou je, že na čele oproti upínacieho otvoru sú vytvořené aspoň dva odstupňované strediace otvory. Po vonkajšom obvode upínacieho kotúča sú vytvořené najmenej dve vybrania prerušujúce strediace otvory.The above-mentioned drawbacks are solved by a technical problem solved by a clamping disk of annular workpieces, in particular on electro-spark drill cutters according to the invention, the principle of which is that at least two graduated centering holes are formed on the face of the clamping hole. At least two recesses interrupting the centering holes are formed along the outer periphery of the clamping disk.

Upínacím kotúčom prstencových obrobkov podta vynálezu sa docieli sproduktívnenie procesu rezania a podstatné sa zlepší operativnost pri výměně prstencových obrobkov rozdielných priemerov. 4According to the invention, the clamping disc of the annular workpieces achieves the production process of the cutting process and the operability to change the annular workpieces of different diameters is substantially improved. 4

Na pripojenom výkrese je znázorněné příkladné riešenie upínacieho kotúča prstencového obrobku na elektroiskrovej drotovej rezačke, kde na obr. 1 je nakréslený v náryse a na obr. 2 je nakreslený upínací kotúč v řeze.In the accompanying drawing, there is shown an exemplary embodiment of an annular workpiece holding disc on an electro-spark drill cutter, wherein in Fig. 1 it is sketched in a front view and in Fig. 2, a clamping disc in section is drawn.

Upínací kotúč 1 má pa jednom čele vytvořený upínací otvor 4 á na druhom čele tri stupně strediacich otvorov 2. V upínačom otvore 4 sú vytvořené štyri otvory 3 pre skrutky. Po obvode upínacieho kotúča 1 je vytvořených šest vybraní 5, ktoré prerušujú strediace otvory 2. Na dne najmenšieho strediaceho otvoru 2 je vytvořených'šest otvorov 6 pre skrutky přítlačného prostriedku (na obr. nezakreslenom).The clamping disc 1 has a clamping hole 4a formed at one face and three stages of centering holes 2 at the other face. Four screw holes 3 are provided in the clamping hole 4. Six recesses 5 are formed around the circumference of the clamping disc 1, which interrupt the centering holes 2. Six holes 6 for the presser means (not shown in the figure) are formed on the bottom of the smallest centering hole 2.

Upínací kotúč 1 sa najskor upevní upínacím otvorom 4 a otvorom 3 na eíektroiskrovú drotovú řezačku. Potom sa prstencový obrobok (na obr. nezakreslený) určený k rozrezaniu zasunie do' příslušného strediaceho otvoru 2 a pevne sa uchytí přítlačnými prostriedkami připevněnými k upínaciemu kotúču 1 pomocou skrutiek umiestnených v otvoroch 6. Pri rozřezávaní prstencového obrobku, drót elektroiskrovej řezačky prechádza cez vybranie 5.The clamping disk 1 is fastened first by the clamping hole 4 and the hole 3 to the electro-sparking wire cutter. Then, the annular workpiece (not shown in the figure) to be cut is inserted into the respective centering hole 2 and fixedly fixed by the pressing means fixed to the clamping disk 1 by means of screws located in the holes 6. When cutting the annular workpiece, the wire of the electro-spark cutter passes through the recess 5 .
