Abstract

Narzedzie wielozwojne do walcowania skosnego wielokrotnego wyrobów typu kula skladajace sie ze stopniowego walca, w sklad którego wchodzi czop napedowy, czopy lozyskowe oraz walec roboczy charakteryzuje sie tym, ze na walcu roboczym od strony przeciwnej do czopa (1) napedowego znajduje sie powierzchnia (4) wejsciowa, która posiada stozkowy ksztalt redukujacy srednice pólfabrykatu, nastepnie za powierzchnia (4) wejsciowa na walcu roboczym znajduje sie walcowa powierzchnia (5) kalibrujaca i podajaca pólfabrykat, zas za powierzchnia (5) kalibrujaca i podajaca znajduje sie powierzchnia (6) wcinania o dlugosci (L1), na której wykonane sa czterozwojne wystepy (9a) srubowe o ksztalcie klinów, rozmieszczone symetrycznie co dziewiecdziesiat stopni na obwodzie walca roboczego, stopniowo zwiekszajace swoja wysokosc i szerokosc, przy czym kat rozwarcia i kat pochylenia klinowych powierzchni bocznych jest staly, zas za powierzchnia (6) wcinania znajduje sie powierzchnia (7) ksztaltowania o dlugosci (L2), w której wykonane sa czterozwojne wystepy (9b) srubowe tworzace wykrój o ksztalcie walcowanych kul o promieniu równym ksztaltowanej kuli, natomiast za powierzchnia (7) ksztaltowania znajduje sie powierzchnia (8) kalibrowania i rozcinania o dlugosci (L3), w której czterozwojne wystepy (9c) srubowe tworzace wykrój zwiekszaja swoja wysokosc i szerokosc, rozdzielajac walcowane kule i kalibruja ich ksztalt, na wystepach (9c) srubowych umieszczone sa noze (10) rozcinajace.Multi-tool for multi-skew rolling of ball type products consisting of a step roller, which includes the drive pin, bearing pins and work roller is characterized by the surface (4) on the work roller from the opposite side to the drive pin (1) The entrance, which has a conical shape reducing the diameter of the blank, then behind the surface (4) on the work cylinder there is a cylindrical surface (5) calibrating and feeding the blank, while behind the surface (5) the calibrating and feeding surface (6) has a cutting length (L1), on which four-protruding projections (9a) are made, wedge-shaped, symmetrically distributed every ninety degrees around the circumference of the work cylinder, gradually increasing its height and width, with the opening angle and the angle of inclination of the wedge side surfaces fixed. indentation surface (6) there is a surface (7) shaping from length (L2), in which four-turn projections (9b) are made, forming a pattern with the shape of rolled balls with a radius equal to the shaped sphere, while behind the surface (7) of the shape there is the surface (8) of calibration and cutting length (L3), whose four-pronged projections (9c) forming the pattern increase its height and width, separating rolled balls and calibrating their shape, on the projections (9c) there are cutting knives (10).
