Abstract
Sposób obciskania obrotowego odkuwek wałów stopniowanych, zwłaszcza drążonych i pełnych wałów bimetalowych charakteryzuje się tym, że półfabrykat, składający się z tulei zewnętrznej wewnątrz której umieszczona jest tuleja wewnętrzna wprowadza się między trzy jednakowe walce (4a, 4b i 4c) w kształcie stopniowanych tulei, które umieszczone są symetrycznie co 120° względem osi walcowania, następnie wprawia się trzy walce (4a, 4b i 4c) w ruch obrotowy w tym samym kierunku i ze stałą prędkością (n1), oraz wprawia się trzy walce (4a, 4b i 4c) w ruch postępowy i przemieszcza się trzy walce (4a, 4b i 4c) ze stałą prędkością (V) w kierunku osi półfabrykatu, następnie oddziałuje się na półfabrykat powierzchniami roboczymi walców (4a, 4b i 4c) i wprawia się półfabrykat w ruch obrotowy w kierunku przeciwnym do kierunku obrotu walców (4a, 4b i 4c), po czym redukuje się kolejne średnice odkuwki (5) i jednocześnie zgrzewa się wewnętrzną ściankę tulei zewnętrznej z zewnętrzną ścianką tulei wewnętrznej i uzyskuje się bimetalową odkuwkę (5) wałka stopniowanego, w której powłoka zewnętrzna (6) wykonana jest z innego materiału niż drążony rdzeń (7) odkuwki (5).The method of rotary crimping of stepped shaft forgings, especially hollow and solid bimetallic shafts, is characterized by the fact that the blank consisting of an outer sleeve inside which an inner sleeve is placed is inserted between three identical rolls (4a, 4b and 4c) in the shape of stepped sleeves, which are placed symmetrically at 120 ° in relation to the rolling axis, then three rolls (4a, 4b and 4c) are rotated in the same direction and at a constant speed (n1), and three rolls (4a, 4b and 4c) are set in translational movement and three rollers (4a, 4b and 4c) are moved at a constant speed (V) towards the axis of the blank, then the blank is influenced by the working surfaces of the rolls (4a, 4b and 4c) and the blank is set in a rotating motion in the opposite direction to the direction of rotation of the rollers (4a, 4b and 4c), then the subsequent diameters of the forging (5) are reduced and the inner wall of the outer sleeve is welded to the outer wall of the inner sleeve and a bimetallic stepped shaft forging (5) is obtained, in which the outer shell (6) is made of a material other than the hollow core (7) of the forging (5).
