Description

Przedmiot wynalazku niniejszego doty¬ czy przyrzadu, który sluzy do ostrzenia konca srubek i który sklada sie z trzech lub wiecej nozy tnacych, ulozonych w ten sposób, ze przy pracy noze te jednocze¬ snie centruja obrabiane srubki, nawet wów¬ czas, jezeli ich os obrotu nie lezy na jed¬ nej linji z osia obrotu nozy.Przyrzad wykonany w mysl wynalazku niniejszego jest przedstawiony jako przy¬ klad na rysunku, na którym fig, 1 wskazu¬ je przyrzad zaostrzajacy w widoku zboku; fig. 2 — ten sam przyrzad w widoku zprzo- du; fig. 3 — przyrzad zaostrzajacy widzia¬ ny zboku w innym kierunku, anizeli przed¬ stawiono na fig. 1 i fig. 4 — trzy przekroje a, b i c po lin j ach a—a, b—6 i c—c noza tnacego, uwidocznionego na fig. 3. Noze tnace 1 do zaostrzenia konców srubek sa w odpowiedni sposób umieszczone w glowicy 2 i zaostrzone tylko w bliskosci osi obrotu obrabianych srubek, reszta ostrza jest za¬ okraglona. Dzieki temu, gdy obrabia sie niezupelnie okragla albo nieprawidlowo wirujaca srubke, wtedy dotyka ona do za¬ okraglonych czesci ostrzy nozów, co po¬ woduje centryczne ustawienie jej, dzieki czemu koniec tej srubki zaostrza sie na¬ stepnie prawidlowo. PLThe subject matter of the present invention relates to an apparatus which serves for sharpening the ends of screws and which consists of three or more cutting knives, arranged in such a way that, during operation, these knives simultaneously center the processed screws, even if their axis rotation is not in line with the axis of rotation of the knives. An example of the present invention is shown as an example in the drawing, in which Fig. 1 shows the sharpening device in a slope view; Fig. 2 is a front view of the same device; Fig. 3 shows the sharpening device of the slope in a different direction than that shown in Fig. 1 and Fig. 4 - three sections a, b and c along the lines a-a, b-6 and c-c of the cutting knife, shown in Fig. 3. The cutting knives 1 for sharpening the ends of the screws are properly positioned in the head 2 and sharpened only in the vicinity of the axis of rotation of the screws to be processed, the rest of the blade is rounded. Thus, when an incompletely round or improperly rotating screw is machined, it touches the rounded portions of the blades, which causes it to be centered so that the tip of the screw sharpens correctly.
