Abstract
Narzędzia do wyciskania stopnia wału drążonego charakteryzują się tym, że stempel z trzpieniem (1) jest usytuowany współosiowo ze stemplem rurowym (4), który posiada wzdłuż własnej osi symetrii otwór przelotowy (5). Stempel rurowy (4) jest umieszczony współosiowo w otworze tulei dolnej (3b) w kształcie pierścienia, której otwór w pierwszej strefie (Ib) od strony stempla rurowego (4) posiada mniejsze pole przekroju poprzecznego niż w drugiej strefie (IIb), zaś powierzchnia czołowa (Y) tulei dolnej (3b) od strony drugiej strefy (IIb) otworu jest prostopadła do osi tulei dolnej (3b) i współpłaszczyznowa z powierzchnią czołową (X) tulei górnej (3a). Sposób wyciskania stopnia wału drążonego charakteryzuje się tym, że do współosiowo umieszczonych tulei górnej (3a) i tulei dolnej (3b) wprowadza się wsad rurowy (7), po czym od strony tulei górnej (3a) wprowadza się stempel z trzpieniem (1), a od strony tulei dolnej (3b) wprowadza się stempel rurowy (4). Następnie wprawia się w ruch postępowy stempel z trzpieniem (1) z prędkością od 0,001 do 1000 mm/s i stempel rurowy (4) z prędkością od 0,001 do 1000 mm/s w kierunku wsadu rurowego (7).The tools for extruding the hollow shaft step are characterized by the fact that the punch with the mandrel (1) is coaxial with the tubular punch (4), which has a through hole (5) along its symmetry axis. The tubular punch (4) is arranged coaxially in the bore of the ring-shaped lower sleeve (3b), the bore of which in the first zone (Ib) on the side of the tubular punch (4) has a smaller cross-sectional area than in the second zone (IIb), and the face surface (Y) of the lower sleeve (3b) from the side of the second zone (IIb) of the opening is perpendicular to the axis of the lower sleeve (3b) and coplanar with the face (X) of the upper sleeve (3a). The method of extrusion of the hollow shaft step is characterized by the fact that a tube charge (7) is introduced into the coaxially placed upper sleeve (3a) and the lower sleeve (3b), and then a punch with a mandrel (1) is inserted from the side of the upper sleeve (3a), and a tubular punch (4) is inserted from the side of the lower sleeve (3b). The punch with the mandrel (1) is then set in translation at a speed of 0.001 to 1000 mm / s and the tubular punch (4) at a speed of 0.001 to 1000 mm / s in the direction of the tubular charge (7).
