Description
Przedmiotem wynalazku jest rolka prowadzaca do prowadnic rolkowych przeznaczonych dla prowadzenia szybko walcowanych materialów, zawierajaca kólko biezne. Prowadnica rolkowa zawiera dwia takie rolki prowa¬ dzace. Prowadnice takie sa znane.The subject of the invention is a guide roller for roller guides intended for guidance rapidly rolled stock, including a running wheel. The roller guide includes two such guide rollers plots. Such guides are known.
W nowoczesnych urzadzeniach do walcowania drutów i pretów, wykonczany produkt przesuwa sie z predkoscia okolo 25 do 30 m/sekunde. Z tego powodu bardzo jest wazne, aby walcowany material wchodzacy do wykroju zespolu walcarek wykonczajacych zachowywal kierunek calkowicie poprawny, zarówno pionowo jak i poziomo, bowiem w przeciwnym przypadku istnieje niebezpieczenstwo zniszczenia materialu walcowanego.In modern wire and rod rolling equipment, the finished product moves at a speed of approximately 25 to 30 m / second. For this reason it is very important that the rolled material comes in to the cut of a set of finishing mills, they kept the direction completely correct, both vertically and horizontally, otherwise there is a risk of the rolled material being damaged.
Z tego powodu przed wykrojem umieszcza sie prowadnice dla walcowanego materialu. W przypadku duzej predkosci walcowania, a zwlaszcza, gdy wymagana jest wysoka jakosc walcowania, stosuje sie tak zwane prowad¬ nice rolkowe, to znaczy powierzchnie ustawiajace zlozone z obrotowych rolek prowadzacych o odpowiedniej budowie.For this reason, guides for the rolled material are provided in front of the blank. In the event of a large rolling speeds, and especially when high-quality rolling is required, so-called guides are used roller screens, that is to say setting surfaces composed of pivoting guide rollers of suitable type construction site.
Rolki sa poddawane poteznym naprezeniom i silnemu zuzyciu. W celu zmniejszenia zuzycia kólko biezne wykonuje sie ze spiekanego weglika. Spiekany weglik jest materialem drogim. Zadaniem zatem wynalazku bylo opracowanie takiej konstrukcji rolki prowadzacej, aby kólko biezne wymagalo zuzycia jak najmniejszej ilosci materialu, a jednoczesnie mialo wytrzymalosc wystarczajaca do pokonania powstajacych naprezen. W zwiazku z tym, aby kólko biezne mialo pewna minimalna grubosc.The rollers are subjected to extreme stresses and high wear. In order to reduce wear the running wheel made of sintered carbide. Sintered carbide is an expensive material. The task of the invention was therefore developing such a structure of the guide roller so that the running wheel requires as little consumption as possible material, and at the same time it has a strength sufficient to overcome the resulting stresses. In relation with provided that the running wheel has a certain minimum thickness.
Wedlug wynalazku rolka prowadzaca, podtrzymywana na nieruchomej cylindrycznej osi zawiera dwa obro¬ towe elementy lozyskujace o ksztalcie scietego stozka, których górne powierzchnie sa skierowane na wzajem ku sobie, a wewnetrzna powierzchnia kólka bieznego, ustawionego na elementach lozyskujacych, ma ksztalt odpo¬ wiednio uzgodniony ze stozkowatoscia elementów lozyskujacych.According to the invention, a guide roller supported on a stationary cylindrical axis comprises two turns these bearing elements in the shape of a conical cone, the upper surfaces of which are directed towards each other itself, and the inner surface of the running wheel, set on the bearing elements, has a shape corresponding to appropriately agreed with the conicity of the bearing elements.
Dzieki takiej konstrukcji uzyskuje sie rolke tania i wytrzymala. Przez zastosowanie wewnetrznej powie¬ rzchni kólka bieznego o ksztalcie stozkowym, obciazenie jest rozlozone w sposób bardziej dogodny, co zmniej¬ sza niebezpieczenstwo tworzenia sie pekniec kólka bieznego ze spiekanych weglików.Thanks to this construction, a cheap and durable roll is obtained. By using the inner air on the cone-shaped running wheel, the load is distributed more conveniently, which reduces There is a greater danger of the formation of cracks in the guide pulley from sintered carbons.
Poza zaleta polegajaca na zmniejszeniu ilosci potrzebnego materialu, uzyskuje sie dalsza zalete, polegajaca na obnizeniu kosztów dzieki temu, ze powierzchnie stozkowe trzeba obrabiac z mniejsza precyzja, niz powie¬ rzchnie walcowe.2 89 324 Rolka wedlug wynalazku jest uwidoczniona w przykladzie jej wykonania na rysunku, na którym fig. 1 przedstawia rolke prowadzaca wedlug wynalazku w przekroju utrzymywana w prowadnicy rolkowej, fig. 2 — rozklad cisnienia w rolce wedlug wynalazku, zas fig. 3 — rozklad cisnienia w rolce konwencjonalnej.Besides the advantage of reducing the amount of material needed, a further advantage is obtained, consisting of lower costs due to the fact that the tapered surfaces have to be processed with less precision than air rollers. 2 89 324 The roller according to the invention is shown in an example of its embodiment in the drawing in which Fig. 1 shows the guide roller according to the invention, in cross-section, held in a roller guide, Fig. 2 shows the pressure distribution in the roller according to the invention, and Fig. 3 shows the pressure distribution in the conventional roller.
Rolka prowadzaca 1 (fig. 1) jest podtrzymywana na nieruchomej osi 2 za pomoca dwu lozysk 3 w postaci scietych stozków. Os 2 jest unieruchomiona w uchwycie rolki 4. Pomiedzy elementami lozyskujacymi 3 jest zacisniety pierscien 5, wyposazony w powierzchnie reakcyjne (nie pokazane na rysunku).The guide roller 1 (Fig. 1) is supported on the fixed axle 2 by means of two bearings 3 in the form cut cones. The axis 2 is fixed in the roller holder 4. There is between the bearing elements 3 clamped ring 5, equipped with reaction surfaces (not shown).
Rolka jest obracana przez dostarczany osrodek napedzajacy i smarujacy, podawany przez przelot 6 w uchwycie rolki i kanaly 7 i 8 w nieruchomej osi. Poniewaz naped i smarowanie nie stanowia przedmiotu wynalazku, szczególy urzadzen napedzajacych i smarujacych nie zostana pokazane. Osrodek napedzajacy po przejsciu przez kolo turbiny 5 jest wydalany przez kanaly 9.The roller is rotated by the supplied drive and lubricant, which is fed through the passage 6 in the roll holder and channels 7 and 8 in the fixed axis. Because drive and lubrication are not a concern of the invention, the details of the driving and lubricating devices will not be shown. Driving center after after passing through the wheel of the turbine 5 is expelled through the channels 9.
Lozysko jest wyposazone w kolowe tarcze 10.The bearing is equipped with 10 discs.
Kólko biezne 11 rolek ma wewnetrzna powierzchnie stozkowa z dwu kierunków, przy czym kat stozka jest taki sam, jak elementów lozyskujacych 3.The track wheel of 11 rollers has an internal conical surface in two directions, with a cone angle it is the same as the bearing elements 3.
Jak przedstawia fig. 2, w kólku bieznym 11 wedlug wynalazku panuje równomierny rozklad cisnienia, co wynika ze stozkowatosci powierzchni wewnetrznej.As shown in Fig. 2, according to the invention, in the track pulley 11 there is a uniform pressure distribution, which it results from the conicity of the inner surface.
Na fig. 3 przedstawiono znane kólko biezne 12. Rozklad cisnienia w tym kólku bieznym nie jest równo¬ mierny, wskutek czego latwo pojawiaja sie pekniecia 13.3 shows a known running wheel 12. The pressure distribution in this running wheel is not equal to mediocre, making it easy to crack 13.
