Description

Przedmiotem wynalazku jest urzadzenie do plyn¬ nej regulacji docisku rolek oporowych do rolek ro¬ boczych prostujacych w prostownicy. Prostownica posiada w kasetach górnej i dolnej rolki oporowe, których oprawy lozysk osadzone sa w prowadni¬ cach slizgowych.Znane prostownice posiadaja oprawy lozysk ro¬ lek oporowych podparte klinami nastawczymi. Oba kliny, na których oparte sa te oprawy osadzone sa w prowadnicach slizgowych i przesuwane za po¬ moca znanego mechanizmu nastawy poprzez srube ^ciagnaca. Wzajemne zblizenie sie lub oddalenie kli¬ nów powoduje przesuwanie sie rolki oporowej pros- topadle do jej osi i regulacje jej docisku do rolki -roboczej.Rozwiazanie takie stwarza mozliwosc nierównor leglego podnoszenia lub opuszczania rolki oporo¬ wej. W krancowym przypadku nierównolegly prze¬ suw rolki powoduje zakleszczenie jednej lub obu opraw w prowadnicy. Nieprawidlqwy docisk lub nawet brak styku rolki oporowej z robocza powo¬ duje szybsze zuzycie rolki oporowej, zas rolka ro¬ bocza moze w takim przypadku ulec peknieciu i .zniszczeniu a lozyska rolek prostujacych roboczych ulegaja przedwczesnemu zuzyciu.Istota wynalazku jest oddzielenie oprawy lozysk rolki oporowej od klina nastawczego przez kon¬ strukcje spelniajaca role przegubu.Pomiedzy podstawa oprawy lozysk rolki oporo- -wej osadzonej w prowadnicy z klinem nastawczym u 15 osadza sie wedlug wynalazku plytke klinowa z wyzlobionym cylindrycznym wglebieniem. Podob¬ ne wglebienie posiada podstawa oprawy lozysk.W tych wglebieniach osadzone sa elementy toczne, które w tym ukladzie kinematycznym pelnia role przegubów.Wzajemne zblizanie lub rozsuwanie klinów po¬ woduje przesuw plytki klinowej i poprzez element toczny przesuw oprawy lozysk rolki oporowej. Prze¬ suw rolki oporowej jest plynny i eliminuje mozli¬ wosc zakleszczenia opraw w prowadnicach. Styk rolek oporowej i roboczej jest zawsze stykiem linio¬ wym nawet, gdy powierzchnie tych rolek nie sa walcowe. Element toczny ma najkorzystniej ksztalt waleczka, co pozwala na przenoszenie duzych na¬ cisków powierzchniowych.Przedmiot wynalazku zostal w przykladowym wykonaniu pokazany na rysunku, przedstawia sche- 20 matyczny widok jednej pary rolek: oporowej i ro¬ boczej w prostownicy.Oprawy 1 lozysk oporowej rolki 2 osadzone sa w slizgowych prowadnicach 3. Podstawy opraw 1 posiadaja cylindryczne wglebienie 4, którym opie- » raja sie o toczne elementy w ksztalcie waleczków 5. Waleczek 5 osadzony jest w cylindrycznym wgle¬ bieniu 6 klinowej plytki 7, która opiera sie swa przeciwlegla powierzchnia o znany nastawczy klin 8. Oba nastawcze kliny 8 osadzone sa na ciagna- M cej srubie 9 znanego mechanizmu nastawy. Obrót -141909141 909 sruby 9 powoduje wzajemne zblizanie sie lub od¬ dalanie klinów 8.Waleczek 5 osadzony w cylindrycznych wglebie¬ niach 4 i 6 spelnia funkcje przegubu i umozliwia równomierny przesuw w pionie oporowej rolki 2 5 dla osiagniecia jej styku liniowego z robocza rol¬ ka 10.Zastrzezenia patentowe 1.

Urzadzenie wedlug zastrz. 1 znamienne tym, ze toczny element <5) ma postac waleczka.WZGraf. Z-d 2 — zam. 670/87 — 90 Cena 130 zl PLThe subject of the invention is a device for smooth adjustment of the pressure of the support rollers to the working rollers of the straightening machine. The straightener has support rollers in the upper and lower cassettes, the bearing housings of which are mounted in sliding guides. Known straighteners have support roller bearings supported by setting wedges. Both wedges on which these housings are based are embedded in slideways and moved by means of a known adjusting mechanism through a tensioning screw. The mutual approach or distance of the wedges causes the thrust roller to move perpendicularly to its axis and the adjustment of its pressure to the work roller. Such a solution allows for unequal lifting or lowering of the resistance roller. In the extreme case, the non-parallel movement of the roller causes one or both of the housings to jam in the guide. Incorrect pressure or even lack of contact between the resistance roller and the working roller causes faster wear of the supporting roller, while the working roller may crack and deteriorate in this case, and the bearings of the working straightening rollers are subject to premature wear. The essence of the invention is to separate the supporting roller bearing from According to the invention, a wedge plate with a hollow cylindrical recess is seated between the base of the stop roller bearing housing, which is mounted in the guide with the adjusting wedge. The base of the bearing housing has a similar indentation. In these indentations, the rolling elements are embedded, which in this kinematic system play the role of joints. When the wedges are brought closer together or apart, the wedge plate moves and the thrust roller bearing moves through the rolling element. The movement of the thrust roller is smooth and eliminates the possibility of jamming the housings in the guides. The contact of the support and working rollers is always linear, even if the surfaces of these rollers are not cylindrical. The rolling element preferably has the shape of a roller, which allows for the transfer of large surface pressure. The subject of the invention has been shown in the exemplary embodiment in the drawing, it shows a schematic view of one pair of rollers: support and working rollers in the straightener. 2 are embedded in sliding guides 3. The bases of the fixtures 1 have a cylindrical recess 4, which rests against the rolling elements in the shape of a roller 5. The roller 5 is embedded in a cylindrical recess 6-wedge plate 7, which rests on its opposite surface o the known adjusting wedge 8. The two adjusting wedges 8 are seated on a tensioning bolt 9 of a known adjusting mechanism. The rotation of the bolt 9 causes the wedges to approach or move away from each other. The roller 5, embedded in the cylindrical recesses 4 and 6, performs the function of a joint and allows for a uniform vertical movement of the support roller 2 5 to achieve its working contact with the roller. ka 10.
