Abstract

Narzędzie do wyciskania stopnia wału drążonego charakteryzuje się tym, że posiada stempel z trzpieniem (1) umieszczony współosiowo w otworze (2) pojemnika górnego (3a) w kształcie pierścienia. Stempel z trzpieniem (1) jest usytuowany współosiowo z wyrzutnikiem (4), który posiada wzdłuż własnej osi symetrii otwór przelotowy (5). Wyrzutnik (4) jest umieszczony współosiowo w otworze (6) pojemnika dolnego (3b) w kształcie pierścienia. Pomiędzy pojemnikiem górnym (3a), a pojemnikiem dolnym (3b) umieszczona jest matryca (7) w kształcie pierścienia, która zamocowana jest do pojemnika górnego (3a). Otwór (8) matrycy (7) w pierwszej strefie (Ia) od strony pojemnika górnego (3a) posiada większe pole przekroju poprzecznego niż w drugiej strefie (IIa), która znajduje się od strony pojemnika dolnego (3b). Otwór (8) matrycy (7) w drugiej strefie (IIa) posiada większe pole przekroju poprzecznego niż otwór (2) pojemnika górnego (3a) i otwór (6) pojemnika dolnego (3b). Otwór (8) matrycy (7) jest współosiowy do otworu (2) pojemnika górnego (3a) i otworu (6) pojemnika dolnego (3b).
