Abstract

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