Abstract
Sposób obciskania obrotowego trzema rolkami wyrobów z gwintami wewnetrznymi, zwlaszcza drazonych odkuwek osiowosymetrycznych z wewnetrznymi wystepami w ksztalcie linii srubowej charakteryzuje sie tym, ze pólfabrykat (3) w ksztalcie tulei umieszcza sie przed trzema jednakowymi narzedziami (1a), (1b) i (1c) w ksztalcie rolek oraz przed trzpieniem (2) gwintowanym, na powierzchni którego znajduja sie srubowe wystepy, przy czym trzpien (2) gwintowany znajduje sie pomiedzy trzema narzedziami (1a), (1b) i (1c), nastepnie narzedzia (1a), (1b) i (1c) wprawia sie w ruch obrotowy w tym samym kierunku i z taka sama predkoscia (n1), zas pólfabrykat (3) wprawia sie w ruch postepowy ze stala predkoscia (V) w kierunku narzedzi (1a), (1b) i (1c) oraz trzpienia (2), w wyniku czego wprawia sie pólfabrykat (3) w ruch obrotowy ze stala predkoscia (n2) w kierunku przeciwnym do ruchu obrotowego narzedzi (1a), (1b) i (1c) i redukuje sie srednice zewnetrzna pólfabrykatu (3), w wyniku czego ksztaltuje sie wewnetrzne wystepy srubowe w pólfabrykacie (3) na trzpieniu (2), przy czym stosunek predkosci (V) postepowej pólfabrykatu (3) do jego predkosci obrotowej (n2) jest równy skokowi ksztaltowanego gwintu, nastepnie po osiagnieciu przez pólfabrykat (3) polozenia koncowego, wylacza sie ruch postepowy pólfabrykatu (3) i jednoczesnie przelacza sie na przeciwny kierunek obrotów narzedzi (1a), (1b), (1c), w wyniku czego wprawia sie uksztaltowany wyrób w ruch obrotowy ze stala predkoscia (n2) oraz ruch postepowy ze stala predkoscia (V).The method of rotary crimping with three rolls of products with internal threads, in particular with axial symmetrical forgings with internal projections in the shape of a screw line, is characterized by the fact that the blank (3) in the shape of a sleeve is placed in front of three identical tools (1a), (1b) and (1b) and in the shape of rollers and in front of the threaded spindle (2), on the surface of which there are screw projections, the threaded spindle (2) is located between three tools (1a), (1b) and (1c), then the tools (1a), ( 1b) and (1c) are set in a rotational motion in the same direction and with the same speed (n1), while the blank (3) is set in progressive motion with a constant speed (V) towards the tool (1a), (1b) and (1c) and the mandrel (2), as a result of which the blank (3) is put into rotation with a constant speed (n2) in the opposite direction to the tool (1a), (1b) and (1c) and the outer diameter is reduced blank (3), as a result of which it is shaped e internal screw protrusions in the blank (3) on the spindle (2), whereby the ratio of the speed (V) of the progressive blank (3) to its rotational speed (n2) is equal to the pitch of the shaped thread, then after reaching the blank (3) the final position , the progress of the blank (3) is switched off and at the same time it switches to the opposite direction of rotation of the tool (1a), (1b), (1c), as a result of which the shaped product is put into rotation at a constant speed (n2) and the progress of movement with constant speed (V).
