Abstract

Sposób kształtowania odkuwek kul drążonych, zwłaszcza metodą obciskania obrotowego trzema narzędziami walcowymi, charakteryzuje się tym, że półfabrykat w kształcie odcinka rury o średnicy zewnętrznej mniejszej od średnicy kształtowanej kuli (7) oraz o średnicy wewnętrznej większej od średnicy trzpienia (2), umieszcza się na trzpieniu (2) między trzema jednakowymi walcami (1a), (1c) roboczymi, następnie wprawia się w ruch obrotowy walce (1a), (1c) robocze w tym samym kierunku i ze stałą prędkością (n1) i jednocześnie przemieszcza się walce (1a), (1c) robocze ze stałą prędkością w kierunku osi trzpienia (2), po czym wprawia się półfabrykat w ruch obrotowy ze stałą prędkością (n2) w kierunku przeciwnym do kierunku obrotów walców (1a), (1c) roboczych, a następnie zagłębia się pierścieniowe występy (4a), (4c) o wklęsłych powierzchniach (5a), (6a), (5c) i (6c) bocznych w półfabrykat i kształtuje się na powierzchni półfabrykatu przewężenia oraz oddziela się półfabrykat na stałe objętości materiału równe objętości kształtowanych kul (7), następnie zgniata się półfabrykat pierścieniowymi występami (4a) i (4c) o wklęsłych powierzchniach (5a), (6a), (5c) i (6c) bocznych i stopniowo redukuje się średnicę przewężeń oraz kształtuje się na trzpieniu (2) kule (7).The method of shaping hollow ball forgings, especially by rotary crimping with three cylindrical tools, is characterized by the fact that a semi-finished product in the shape of a pipe section with an external diameter smaller than the diameter of the shaped ball (7) and an internal diameter larger than the diameter of the shank (2) is placed on mandrel (2) between three identical working rolls (1a), (1c), then the working rolls (1a), (1c) are set in rotation in the same direction and at a constant speed (n1) and at the same time the rolls (1a) are moved ), (1c) working at a constant speed towards the axis of the pin (2), then the semi-finished product is set in rotation at a constant speed (n2) in the direction opposite to the direction of rotation of the working rolls (1a), (1c), and then ring projections (4a), (4c) with concave side surfaces (5a), (6a), (5c) and (6c) are formed into a semi-finished product, and constrictions are formed on the surface of the semi-finished product, and the semi-finished product is separated into constant volumes of material equal to the volume of the shaped balls (7), then the semi-finished product is crushed with ring projections (4a) and (4c) with concave side surfaces (5a), (6a), (5c) and (6c), and the diameter of the constrictions is gradually reduced and shaped on the mandrel (2). balls (7).
