Abstract

Przedmiotem zgłoszenia jest sposób cięcia wzdłużnego szyn, zwłaszcza szyn złomowanych, który polega na tym, że odcinek złomowanej szyny (12) umieszcza się na rolkach podporowych (1) oraz (2) w ten sposób, że środnik złomowanej szyny (12) styka się z powierzchniami zewnętrznymi rolek podporowych (1) i (2), następnie wprawia się rolki podporowe (1) oraz (2) w ruch obrotowy w tym samym kierunku i ze stałą prędkością (n1) i przemieszcza się odcinek złomowanej szyny (12) ze stałą prędkością (V) w kierunku pierwszej pary stożkowych rolek nagniatających (3) oraz (4), następnie wprawia się stożkowe rolki nagniatające (3) i (4) w ruch obrotowy z jednakowymi prędkościami (n2) w przeciwnych do siebie kierunkach, po czym chwyta się środnik szyny złomowanej szyny (12) w pobliżu stopy złomowanej szyny (12) kołnierzem nagniatającym o stożkowych powierzchniach bocznych rolki nagniatającej (3), znajdującej się poniżej złomowanej szyny kolejowej (12) oraz kołnierzem nagniatającym o stożkowych powierzchniach bocznych rolki nagniatającej (4) znajdującej się powyżej złomowanej szyny kolejowej (12) i nagniata się po obu stronach środnika złomowanej szyny kolejowej (12) w pobliżu stopy złomowanej szyny kolejowej (12) wzdłużne bruzdy na głębokość (g), która jest mniejsza od połowy grubości środnika złomowanej szyny kolejowej (12).The subject of the application is a method of longitudinal cutting of rails, especially scrapped rails, which consists in placing a section of the scrapped rail (12) on the support rollers (1) and (2) in such a way that the web of the scrapped rail (12) is in contact with external surfaces of the support rollers (1) and (2), then the support rollers (1) and (2) are set in rotation in the same direction and at a constant speed (n1), and the section of the scrapped rail (12) is moved at a constant speed (V) towards the first pair of conical burnishing rollers (3) and (4), then the conical burnishing rollers (3) and (4) are set in rotation with equal speeds (n2) in opposite directions, and then gripped rail web of the scrapped rail (12) near the foot of the scrapped rail (12) with a burnishing flange with conical side surfaces of the burnishing roller (3) located below the scrapped railway rail (12) and a burnishing flange with conical side surfaces of the burnishing roller (4) located above the scrapped railway rail (12) and longitudinal grooves are burnt on both sides of the web of the scrapped railway rail (12) near the foot of the scrapped railway rail (12) to a depth (g) that is less than half the thickness of the web of the scrapped railway rail (12). .
