Abstract
Sposób obciskania obrotowego uzebien wewnetrznych, zwlaszcza wyrobów drazonych z wewnetrznymi wystepami w ksztalcie wielowypustów, wielokarbów i uzebien charakteryzuje sie tym, ze pólfabrykat w ksztalcie tulei umieszcza sie miedzy trzema jednakowymi narzedziami (1a), (1b) i (1c) w ksztalcie rolek, natomiast wewnatrz pólfabrykatu umieszcza sie trzpien (2) ksztaltowy, na powierzchni którego znajduje sie uzebienie zewnetrzne, nastepnie narzedzia (1a), (1b) i (1c) wprawia sie w ruch obrotowy w tym samym kierunku i z taka sama predkoscia (n1) oraz ruch postepowy w kierunku osi pólfabrykatu ze stala predkoscia, w wyniku czego wprawia sie pólfabrykat oraz umieszczony wewnatrz niego trzpien (2) ksztaltowy w ruch obrotowy ze stala predkoscia n2 w kierunku przeciwnym do ruchu obrotowego narzedzi (1a), (1b) i (1c) i redukuje sie srednice zewnetrzna pólfabrykatu, w wyniku czego ksztaltuje sie wewnetrzne uzebienie w pólfabrykacie na trzpieniu (2), po osiagnieciu przez narzedzia (1a), (1b) i (1c) polozenia koncowego wylacza sie ich ruch postepowy, zas narzedzia (1a), (1b), (1c) obracaja sie ze stala predkoscia (n1), w wyniku czego, kalibruje sie uksztaltowane uzebienie wewnetrzne w wyrobie (4), nastepnie uruchamia sie ruch postepowy trzpienia (2) ksztaltowego ze stala predkoscia V0 wzdluz jego osi i wysuwa sie trzpien (2) ksztaltowy z wyrobu (4) z uzebieniem wewnetrznym.The method of rotary crimping of internal teeth, especially for hollow products with internal projections in the shape of splines, notches and teeth, is characterized by the fact that the blank in the shape of a sleeve is placed between three identical tools (1a), (1b) and (1c) in the shape of inside the blank there is a mandrel (2) shaped, on the surface of which the external teeth are located, then tools (1a), (1b) and (1c) are set in rotational motion in the same direction and with the same speed (n1) and towards the axis of the blank with a constant speed, as a result of which the blank and the mandrel (2) placed inside it rotate with constant speed n2 in the opposite direction to the tool (1a), (1b) and (1c) rotation and reduce external diameter of the blank, as a result of which the internal teeth are formed in the blank on the shank (2), after reaching by the tools (1a), (1b ) and (1c) their final position, their progress is switched off, while the tools (1a), (1b), (1c) rotate at a constant speed (n1), as a result of which the shaped internal teeth in the product are calibrated (4), then the forward movement of the shank (2) with constant speed V0 is started along its axis and the shank (2) with the internal teeth is extended (2).
