Abstract

Przedmiotem zgłoszenia jest narzędzie do wyciskania stopni wału pełnego, które charakteryzuje się tym, że posiada stempel górny (1), który umieszczony jest współosiowo w otworze (2) pojemnika górnego (3a) w kształcie pierścienia. Stempel górny (1) jest usytuowany współosiowo ze stemplem dolnym (4). Stempel dolny (4) jest umieszczony współosiowo w otworze (5) pojemnika dolnego (3b) w kształcie pierścienia. Pomiędzy pojemnikiem dolnym (3b), a pojemnikiem górnym (3a) umieszczona jest matryca dzielona (6) w kształcie pierścienia, której otwór (7) jest współosiowy do otworu (5) pojemnika dolnego (3b) i otworu (2) pojemnika górnego (3a). Pomiędzy pojemnikiem górnym (3a), a matrycą dzieloną (6) umieszczona jest matryca górna (8a) w kształcie pierścienia, która zamocowana jest do pojemnika górnego (3a). Otwór (9) matrycy górnej (8a) w pierwszej strefie (Ia) od strony pojemnika górnego (3a) posiada większe pole przekroju poprzecznego niż w drugiej strefie (IIa), która znajduje się od strony matrycy dzielonej (6). Otwór (9) matrycy górnej (8a) w drugiej strefie (IIa) posiada większe pole przekroju poprzecznego niż otwór (2) pojemnika górnego (3a). Pomiędzy pojemnikiem dolnym (3b), a matrycą dzieloną (6) umieszczona jest matryca dolna (8b) w kształcie pierścienia, która zamocowana jest do pojemnika dolnego (3b). Otwór (10) matrycy dolnej (8b) w pierwszej strefie (Ib) od strony pojemnika dolnego (3b) posiada większe pole przekroju poprzecznego niż w drugiej strefie (IIb), która znajduje się od strony matrycy dzielonej (6). Otwór (10) matrycy dolnej (8b) w drugiej strefie (IIb) posiada większe pole przekroju poprzecznego niż otwór (5) pojemnika dolnego (3b). Otwór (9) matrycy górnej (8a) i otwór (10) matrycy dolnej (8b) są współosiowe do otworu (7) matrycy dzielonej (6).The subject of the application is a tool for extruding stages of a solid shaft, which is characterized by having an upper punch (1), which is placed coaxially in the hole (2) of the upper ring-shaped container (3a). The upper punch (1) is located coaxially with the lower punch (4). The lower punch (4) is placed coaxially in the ring-shaped opening (5) of the lower container (3b). Between the lower container (3b) and the upper container (3a) there is a ring-shaped split die (6), the opening (7) of which is coaxial to the opening (5) of the lower container (3b) and the opening (2) of the upper container (3a). ). Between the upper container (3a) and the divided matrix (6) there is an upper matrix (8a) in the shape of a ring, which is attached to the upper container (3a). The opening (9) of the upper die (8a) in the first zone (Ia) on the side of the upper container (3a) has a larger cross-sectional area than in the second zone (IIa), which is located on the side of the divided die (6). The opening (9) of the upper die (8a) in the second zone (IIa) has a larger cross-sectional area than the opening (2) of the upper container (3a). Between the lower container (3b) and the divided matrix (6) there is a lower matrix (8b) in the shape of a ring, which is attached to the lower container (3b). The opening (10) of the lower die (8b) in the first zone (Ib) on the side of the lower container (3b) has a larger cross-sectional area than in the second zone (IIb), which is located on the side of the split die (6). The opening (10) of the lower die (8b) in the second zone (IIb) has a larger cross-sectional area than the opening (5) of the lower container (3b). The opening (9) of the upper die (8a) and the opening (10) of the lower die (8b) are coaxial to the opening (7) of the split die (6).
