Abstract

Narzędzie klinowe do dwuetapowego walcowania odkuwek, zwłaszcza do walcowania poprzeczno - klinowego odkuwek osiowosymetrycznych stopniowanych osi i wałów w kształcie dwóch walców o klinowych powierzchniach roboczych charakteryzuje się tym, że składa się z walca roboczego (1) do kształtowania w pierwszym etapie oraz walca roboczego (2) do walcowania w drugim etapie, przy czym obwód walca roboczego (1) do kształtowania w pierwszym etapie jest podzielony kolejno na strefę załadunkowo-wyładunkową strefę kształtowania stopnia środkowego oraz strefę kalibrowania, zaś obwód walca roboczego (2) do walcowania w drugim etapie jest podzielony kolejno na strefę załadunkową, strefę pozycjonowania półwyrobu, strefę kształtowania stopni stożkowych (VI), strefę kształtowania skrajnych stopni (VII), strefę kalibrowania oraz strefę wyładunkową. Na walcu roboczym (1) do kształtowania w pierwszym etapie znajduje się strefa załadunkowo-wyładunkowa, która ma kształt powierzchni cylindrycznej (3) pokrywającej się z powierzchnią walca roboczego, następnie za strefą załadunkowo-wyładunkową znajduje się strefa kształtowania (II) stopnia środkowego, w której na powierzchni cylindrycznej (3) znajduje się centralny występ klinowy (4) o stałym kącie rozwarcia klina.The wedge tool for two-stage rolling of forgings, especially for cross-wedge rolling of axial-symmetrical forgings of stepped axes and shafts in the shape of two cylinders with wedge-shaped work surfaces is characterized by the fact that it consists of a work cylinder (1) for shaping in the first stage and a work cylinder (2 ) for rolling in the second stage, where the circumference of the work roll (1) for shaping in the first stage is divided successively into the loading and unloading zone, the middle stage shaping zone and the calibration zone, while the circumference of the work roller (2) for rolling in the second stage is divided in succession to the loading zone, the positioning position of the blank, the conical stage shaping zone (VI), the extreme stage shaping zone (VII), the calibration zone and the unloading zone. On the work roll (1) for shaping in the first stage there is a loading-unloading zone, which has the shape of a cylindrical surface (3) coinciding with the surface of the work roll, then behind the loading-unloading zone there is a shaping zone (II) of the middle stage, in on the cylindrical surface (3) there is a central wedge projection (4) with a fixed wedge angle.
