Abstract

Inventia se refera la prelucrarea metalelor prin presare. Dispozitivul de stantare a sinmifabricatelor prin rulare include un corp cav cu un capac, in care este amplasata o portscula cu suprafata de reazem sferica, imbinata cu suprafata sferica a unui reazem fixat rigid in corp si un mecanism de actionare a portsculei, ce contine o roata dintata conducatoare. Noutatea inventiei consta in aceea ca reazemul este executat in forma unei roti centrale dintate cu dinti laterali, pe suprafata exterioara laterala a butucului caruia este instalata, cu posibilitatea rotirii, roata dintata conducatoare a mecanismului de actionare a portsculei, care se afla in angrenare cu roata dintata de actionare, amplasata radial in corp. In capac este montat cu posibilitatea rotirii un element opritor fixat rigid pe butucul rotii dintate conducatoare, totodata suprafetele lor laterale inversate sunt executate inclinate si paralele, iar in interstitiul dintre ele este amplasata flansa portsculei. Portscula este executata ca un satelit cu dinti in forma unor role rotitoare, ce angreneaza cu dintii rotii centrale dintate. La periferia ambelor suprafete ale flansei sunt executate caneluri inelare, in care sunt amplasate corpuri de rulare ce contacteaza cu suprafetele inclinate corespunzatoare ale rotii dintate conducatoare si ale elementului opritor. ŕThe invention relates to the processing of metals by pressing. The stamping device for rolling mills includes a hollow body with a lid, in which is located a spacer with a spherical support surface, combined with the spherical surface of a support fixed rigidly in the body and a mechanism for actuating the spindle, which contains a wheel. tooth gear. The novelty of the invention consists in that the support is executed in the form of a central gear toothed with lateral teeth, on the outer outer surface of the hub which is installed, with the possibility of rotation, the gear tooth driving the mechanism of actuation of the carrier, which is in gear with the wheel actuation tooth, radially located in the body. In the lid is mounted with the possibility of rotating a stiffening element fixed rigidly on the hub of the gear tooth, at the same time their inverted lateral surfaces are executed inclined and parallel, and in the interstitial between them is located the flange of the port. The portscula is executed as a satellite with teeth in the form of rotating rollers, which engages with the teeth central gear wheels. At the periphery of both surfaces of the flange ring grooves are executed, in which rolling bodies are located which contact the corresponding inclined surfaces of the driving gear wheel and of the stopping element. à
