Abstract

Przedmiotem wynalazku jest sposób kształtowania pierścieni bezszwowych w procesie walcowania i zespół do kształtowania pierścieni bezszwowych w procesie walcowania na gorąco, gdzie pierścienie walcowe mają zastosowanie w produkcji wielkogabarytowych elementów łożysk ślizgowych, łożysk tocznych, w tarczach turbin lub w półfabrykatach do produkcji przekładni. Sposób polega na tym, że walcem głównym jako narzędziem kształtującym, o budowie segmentowej w postaci walcowego segmentu bazowego (1) i walcowego segmentu wymiennego (2) centrowanego w swojej dolnej części na powierzchni cylindrycznej lub stożkowej walcowego segmentu bazowego (1), które to segmenty (1, 2) łączy się za pomocą połączenia kształtowego o przekroju wielokąta foremnego (12) współosiowo w środkowej części walcowego segmentu bazowego (1), kształtuje się poprzez walcowanie na walcarce zewnętrzny zarys pierścienia (4), podczas gdy trzpień (5) tworzy zarys wewnętrzny pierścienia (4), gdzie zmniejszając grubość ścianki i wysokość pierścienia (4), średnica pierścienia (4) zwiększa się przy zachowaniu stałej objętości, przy czym proces walcowania kończy się, gdy pierścień (4) osiągnie pożądany kształt i średnicę. Zespół charakteryzuje tym, że walec główny jest narzędziem kształtującym o budowie segmentowej, który składa się z walcowego segmentu bazowego (1), osadzonego na wale napędowym (3) walcarki, gdzie przeniesienie momentu z wału napędowego (3) na segment walca bazowego (1) następuje za pomocą prostokątnych wpustów (8); oraz z walcowego segmentu wymiennego (2), którego dolna część osadzona jest współosiowo i centrowana na cylindrycznej lub stożkowej powierzchni walcowego segmentu bazowego (1), natomiast jego górna część połączona jest kształtowo ze środkową częścią walcowego segmentu bazowego (1) poprzez wzajemnie ukształtowane powierzchnie obu walcowych segmentów: bazowego (1) i wymiennego (2) w postaci wielokątów foremnych (12), ponadto na walcowym segmencie bazowym (1) i czołowej górnej powierzchni walcowego segmentu wymiennego (2) umiejscowiony jest osiowo pełny pierścień (9), natomiast w walcowym segmencie bazowym osiowo umiejscowiony jest pierścień dzielony (10) z obejmą (13) do demontażu i  wymiany walcowego segmentu wymiennego (2).The subject of the invention is a method of shaping seamless rings in the rolling process and a unit for shaping seamless rings in the hot rolling process, where cylindrical rings are used in the production of large-size elements of slide bearings, rolling bearings, in turbine discs or in semi-finished products for the production of gears. The method consists in the fact that the main roller as a shaping tool, with a segment structure in the form of a cylindrical base segment (1) and a cylindrical replaceable segment (2) centered in its lower part on the cylindrical or conical surface of the cylindrical base segment (1), which segments (1, 2) are joined by a form fit with a regular polygon cross-section (12) coaxially in the central part of the cylindrical base segment (1), the outer contour of the ring (4) is formed by rolling on a rolling mill, while the mandrel (5) forms the contour the inner ring (4), whereby by reducing the wall thickness and the height of the ring (4), the diameter of the ring (4) increases while maintaining a constant volume, the rolling process terminating when the ring (4) reaches the desired shape and diameter. The unit is characterized by the fact that the main roll is a shaping tool with a segmental structure, which consists of a cylindrical base segment (1), mounted on the drive shaft (3) of the rolling mill, where the torque transmission from the drive shaft (3) to the base roll segment (1) is performed by means of rectangular keys (8); and a cylindrical exchange segment (2), the lower part of which is mounted coaxially and centered on the cylindrical or conical surface of the cylindrical base segment (1), while its upper part is positively connected with the middle part of the cylindrical base segment (1) through mutually shaped surfaces of both cylindrical segments: base (1) and exchangeable (2) in the form of regular polygons (12), moreover, on the cylindrical base segment (1) and the front upper surface of the cylindrical replaceable segment (2), a full ring (9) is axially located, while in the cylindrical In the base segment, the split ring (10) is axially located with a clamp (13) for disassembling and replacing the cylindrical replaceable segment (2).
