Abstract

Sposób kucia kul w wykroju zamkniętym, zwłaszcza kul o dużych wymiarach z główek złomowanych szyn, charakteryzuje się tym, że wsad w kształcie główki złomowanej szyny nagrzewa się do temperatury kształtowania na gorąco, która wynosi od 1000°C do 1250°C, następnie od nagrzanego wsadu odcina się półfabrykat (8) na długość h > dk, przy czym długość (h) półfabrykatu (8) określa się w ten sposób, aby masa półfabrykatu (8) była równa masie kształtowanej kuli (9), następnie półfabrykat (8) umieszcza się w zamkniętym wykroju, który znajduje się w dzielonej matrycy (2a) lewej oraz dzielonej matrycy (2b) prawej, po czym dzieloną matrycę (2a) lewą oraz dzieloną matrycę (2b) prawą zaciska się na powierzchniach (5a i 5b) stożkowych w otworze stożkowym pierścienia (1) oporowego, po czym wprawia się stempel (6) w ruch roboczy i przemieszcza się stempel (6) ze stałą prędkością (V) w otworze cylindrycznym, znajdującym się w górnej części dzielonej matrycy (2a) lewej oraz w górnej części dzielonej matrycy (2b) prawej w kierunku półfabrykatu (8), po czym oddziaływuje się sferyczną powierzchnią (7) stempla (6) na półfabrykat (8) i spęcza się półfabrykat (7), po czym wypełnia się dolną część zamkniętego wykroju o sferycznych powierzchniach (4a i 4b) roboczych i kształtuje się kule (8).The method of forging balls in a closed pattern, especially bullets with large dimensions from the heads of scraped rails, is characterized by the fact that the head-shaped charge of the scraped rail is heated to the hot forming temperature, which is from 1000 ° C to 1250 ° C, then from heated the charge is cut off the blank (8) to the length h> dk, whereby the length (h) of the blank (8) is determined in such a way that the weight of the blank (8) is equal to the weight of the shaped ball (9), then the blank (8) places in a closed pattern, which is located in the left split matrix (2a) and the right split matrix (2b), then the split left matrix (2a) and the split right matrix (2b) are clamped on the conical surfaces (5a and 5b) in the hole conical stop ring (1), after which the punch (6) is set in motion and the punch (6) moves at a constant speed (V) in the cylindrical hole in the upper part ci of the split matrix (2a) left and in the upper part of the split matrix (2b) right towards the blank (8), after which the spherical surface (7) of the punch (6) acts on the blank (8) and the blank (7) swells, then the lower part of the closed pattern with spherical surfaces (4a and 4b) is filled and the spheres (8) are formed.
