Abstract
Sposób walcowania skośnego, zwłaszcza prętów o przekroju kołowym z główek złomowanych szyn kolejowych charakteryzuje się tym, że półfabrykat w kształcie odcinka główki odciętej od złomowanej szyny kolejowej umieszcza się w tulei (3) prowadzącej, znajdującej się w przestrzeni wejściowej dwóch walców (1a) i (1b) roboczych oraz dwóch prowadnic (2a) i (2b), po czym wprawia się w ruch obrotowy walce (1a) i (1b) robocze w tym samym kierunku i z taką samą prędkością (n1), a następnie wprowadza się w ruch postępowy popychacz (5) i przemieszcza się półfabrykat ze stałą prędkością (V) między obracające się walce (1a) i (1b) oraz dwie prowadnice (2a) i (2b), następnie zagłębia się kołnierze (9a) i (9b) śrubowe o zarysie klinowym, które znajdują się na powierzchniach (8a) i (8b) cylindrycznych walców (1a) i (1b) w półfabrykat wprawia się półfabrykatów ruch obrotowy ze stałą prędkością (n2) w kierunku przeciwnym do kierunku obrotów walców (1a) i (1b) roboczych, oraz jednocześnie przemieszcza się półfabrykat między obracającymi się walcami (1a) i (1b) roboczymi i kształtuje się na powierzchni półfabrykatu pierścieniowe przewężenia, które następnie stopniowo zgniata się śrubowymi występami (9a) i (9b) i redukuje się przekrój poprzeczny półfabrykatu.The method of oblique rolling, especially bars with a circular cross-section from the heads of scrapped railway rails, is characterized by the fact that a semi-finished product in the shape of a section of the head cut off from a scrapped railway rail is placed in the guide sleeve (3), located in the input space of two rolls (1a) and ( 1b) working and two guides (2a) and (2b), then the working rollers (1a) and (1b) are set in rotation in the same direction and at the same speed (n1), and then the pusher is set in translational motion (5) and the semi-finished product moves at a constant speed (V) between the rotating rollers (1a) and (1b) and two guides (2a) and (2b), then the wedge-shaped screw flanges (9a) and (9b) are inserted , which are located on the surfaces (8a) and (8b) of cylindrical rolls (1a) and (1b), the semi-finished products are rotated at a constant speed (n2) in the direction opposite to the direction of rotation of the working rolls (1a) and (1b). , and at the same time, the semi-finished product moves between the rotating working rolls (1a) and (1b) and annular constrictions are formed on the surface of the semi-finished product, which are then gradually crushed by the screw protrusions (9a) and (9b) and the cross-section of the semi-finished product is reduced.
