Description

Przedmiotem wynalazku jest glowica do radelkowania prostego powierzchni przedmiotu, szczególnie przydatna do obróbki dlugich walków dla których wymagana jest prostolinio- wosc wygniatanego ksztaltu.Znane narzedzia do radelkowania prostego maja postaó rolki na obwodzie której na¬ niesiony jest pelny zarys ksztaltowanej powierzchni. Radelkowanie powierzchni na dlugich walkach odbywa sie przez obtaczanie sie rolki po powierzchni walka wzdluz linii srubo¬ wej poprzez nadanie jej posuwu wzdluznego wzgledem obracajacego sie przedmiotu.Istota wynalazku polega na tym, ze glowica ma stos segmentów umieszczony wspólosiowo pomiedzy pierscieniami i polaczony w sztywna calosc kolkami dystansowymi. Segmenty obró¬ cone sa wzajemnie wokól osi glowicy o kat odpowiadajacy podzialce radelkowania. W kazdym segmencie osadzone sa co najmniej dwie rolki ksztaltujace pojedynczy zarys radelkowane- go wglebienia.Zaleta rozwiazania wedlug wynalazku jest mozliwosc obróbki powierzchni przez prze¬ ciaganie lub przepychanie i tym samym otrzymania powierzchni o wyzszej dokladnosci ksztal¬ tu jak liniowosc i owalnosc. Zastosowanie glowicy do obróbki dlugich walków znacznie skraca czas obróbki.Przedmiot wynalazku jest przedstawiony w przykladzie wykonania na zalaczonym rysun¬ ku, na którym fig. 1 przedstawia glowice w przekroju wzdluznym, fig. 2 glowice w widoku czolowym z czesciowym przekrojem. Stos segmentów 1 umieszczony jest wspólosiowo pomie¬ dzy pierscieniami 3 i polaczony w sztywna calosc kolkami dystansowymi 4. Segmenty 1 obrócone sa wzajemnie wokól osi glowicy o kat odpowiadajacy podzialce radelkowania. W segmencie osadzone sa obrotowo rolki ksztaltujace 2 pojedynczy zarys radelkowanego rowka• 148 7982 148 798 Alternatywnym rozwiazaniem rozszerzajacym zakres obrabianych srednic jest osadzenie rolek ksztaltujacych 2 przesuwnie w segmencie 1 z mozliwoscia regulacji nastawy doosiowe- go wysuwu rolek 2.Dzialanie glowicy polega na tym, ze dla wykonania radelkowanej powierzchni nadaje sie glowicy-narzedziu ruch wzdluzny wzgledem przedmiotu.Zastrzezenie patentowe Glowica do radelkowania prostego z rolkami ksztaltujacymi znamienna tym, ze posiada stos segmentów /l/ umieszczony wspólosiowo pomiedzy pierscieniami /3/ polaczonymi w sztywna calosc kolkami dystansowymi /4/f przy czym segmenty /l/ obrócone sa wzajemnie wokól osi glowicy o kat odpowiadajacy podzialce radelkowania, a w kazdym segmencie /l/ sa osadzone co najmniej dwie rolki ksztaltujace /2/ pojedynczy zarys rodel- kowanego wglebienia.Pracownia Poligraficzna UP PRL. Naklad 100 egz.Cena 400 zl PLThe subject of the invention is a head for straight knurling of an object surface, especially useful for processing long rolls for which straightness of the embossed shape is required. Known tools for straight knurling have the form of a roll on the circumference of which a complete contour of the shaped surface is provided. The knurling of the surface on long battles is carried out by rolling the roller on the surface of the roller along the bolt line by giving it a longitudinal feed relative to the rotating object. The essence of the invention consists in the fact that the head has a stack of segments coaxially located between the rings and connected in a rigid whole with rings spacers. The segments are rotated to each other around the axis of the head by an angle corresponding to the pitch of the knurling. In each segment are embedded at least two rollers shaping a single contour of the knurled indentation. An advantage of the solution according to the invention is the possibility of surface treatment by pulling or pushing, and thus obtaining a surface with higher accuracy of shape, such as linearity and ovality. The use of the head for machining long rolls considerably reduces the processing time. The subject of the invention is illustrated in an exemplary embodiment in the accompanying drawing, in which Fig. 1 shows the heads in longitudinal section, Fig. 2 shows the heads in a partial sectional view. The stack of segments 1 is arranged coaxially between the rings 3 and connected to a rigid whole with distance pins 4. The segments 1 are rotated around the axis of the head by an angle corresponding to the pitch of the knurling. In the segment there are rotatingly mounted forming rollers 2 single contours of the knurled groove • 148 7982 148 798 An alternative solution extending the range of machined diameters is to mount the forming rollers 2 slidably in segment 1 with the possibility of adjusting the axial extension of the rollers 2. The head operation consists in the fact that for the execution of the knurled surface, the head-tool is longitudinally moved in relation to the object.
