Abstract
Głowica wytłaczarska, zwłaszcza do wytłaczania przewodów z tworzyw polimerowych z kanałami funkcjonalnymi posiadająca korpus w kształcie wydrążonego walca, element w części wejściowej w kształcie tulei prowadzący tworzywo, element prowadzący tworzywo w kształcie stożka ściętego w części środkowej oraz rdzeń formujący, wraz z dyszą formującą w części wyjściowej, charakteryzuje się tym, że rdzeń (1) formujący o zarysie walca składa się z od dwóch do czterech trzpieni (2), których przekrój poprzeczny stanowi symetryczna figura geometryczna zaś w rdzeniu (1) formującym oraz elemencie (3) prowadzącym w kształcie stożka ściętego znajduje się kanał (4) o przekroju poprzecznym w kształcie symetrycznej figury geometrycznej, przy czym trzpienie (2) rozmieszczone są symetrycznie względem siebie.Extrusion head, in particular for extruding polymer plastic pipes with functional channels, having a body in the shape of a hollow cylinder, a sleeve-shaped element guiding the material in the input part, a material guiding element in the shape of a truncated cone in the central part and a forming core, together with a forming nozzle in the part output, is characterized by the fact that the forming core (1) with a cylindrical outline consists of two to four pins (2), the cross-section of which is a symmetrical geometric figure, and in the forming core (1) and the guide element (3) in the shape of a cone truncated, there is a channel (4) with a cross-section in the shape of a symmetrical geometric figure, with the pins (2) arranged symmetrically to each other.
