fy &/cb Wynalazek niniejszy dotyczy walcarek, w których walec górny obraca si& stale, dol¬ ny zas sprzega sie z górnym tylko przejscio¬ wo i po kazdym obrocie tego ostatniego sa¬ moczynnie powraca do stanu pierwotnego.Wynalazek polega na tern, ze glówki ma¬ tryc obu walców jak równiez, sprzegajace chwilowo walce, dzwona zebate, sa wymien¬ ne; rzeczone glówki moga byc /zastapione pierscieniami o wyciskach nakladanych na walce, zas dzwona zebate przez pelne, ewen¬ tualnie, równiez, z kilku czesci zlozone kolo zebate. " .Takie udoskonaleinie walca ma ten sku¬ tek, ze jedna i ta sama maszyna moze byc uzyta raz z ruchem zwrotnym walca dolne¬ go, a innym razem z ciaglym ruchem obro¬ towym obu walców, co umozliwia lepsze, ekonomiczniejsze wyzyskanie walcarki.Zalaczony rysunek przedstawia w postaci przyklada wzór wykonania wynalazku, a mianowicie fig. 1 walce z ruchem obroto¬ wym ciaglym ziprzodu, fig. 2 — te saime walce w widoku bocznym, wzglednie w prze¬ kroju wzdluz linji A—B na fig. 1, fig. 3 iA— odpowiednie walce w wykonaniu dotychcza- sowem z ruchem zwrotnym walca dolnego, po kazdym obrocie maszyny.Litery a i b oznaczaja walce maszyny, umieszczone jeden nad drugimi w stojakach c i d, przyczem walec górny a obraca; sie sta¬ le, bedac porusizany sposobem znanym. Zgod¬ nie z doitychciziasowiem zwyklem wykonaniem (fig. 3 i 4) walec górny a posiada dwie glów¬ ki matryc e i /, lezace wzgledem siebie sred¬ nicowo' przeciwlegle i polaczone z matryca, osadzona siwa glówka g w walcu dolnym b.Odpowiednio walec górny a zaopatrzony jestw dwa dzwona zebate h i ?', osadzone jedna¬ kowo 'w'zipede'M" powek matryc e i f, oraz walec dolny b, z dzwonem zebatern k, osa- dizcmem równiez jednakowo, w-stosunku-do glówki matrycy g. Na osi walcia dolnego b jeBt z zewnatrz stoj&lka c umocowana dzwi¬ gnia z przeciwwaga l, wywolujaca ruch zwrotny walca b, po kazdym cibrccie ma¬ szyny.Proste to urzadzenie dziala w ten spo¬ sób, ze podczas/kazdego obrotu w^alca gór¬ nego a powstaja -dwa biegi, a mianowicie wspóldzialaja raz'glówka; matrycy e, drugi raz glówka matrycy f walca górnego- z glów¬ ka g matrycy walca: dolnego, zas podczas calego obrotu maszyny dzwona zebate // i k sprzegaja oba walce. Po kazdym biegu, jak to juz zaznaczono, walec dolny b wraca do stanu pierwotnego pod wplywem przeciw¬ wagi.W mysl wynalazku, matryce e, /, {//.osa¬ dzaja sie na walcach wymiennie. W tym celu sa one, w danym przykladzie, osadzone kazda swym dolnym wystepem m w klino¬ watym kanale podluznym walca i zamoco¬ wane klinem, po którego zluzowaniu matry¬ ce mozna usunac. Równiez walec dolny po¬ siada dwa naprzeciwlegle sobie kanaly po¬ dluzne n. Umieszczone nazewnatrz ramy dzwona zebate h i k sa zamocowarne na osiach walców wymiennie zapoimoca gwintów.Chcac, aly maszyna pracowala ruchem cia¬ glym obu walców, nakladamy na oba walce i mocujemy wza.mi.an matryc dwa pólpier- scienie q, i ewent. s, t, tworzac razem pier¬ scien z wyciskami. Mocujemy je na walcu tafle sarnio, jalk i1 matryce, mianowicie zapo- moca wystepu m, wchodzacego w podluzny kaaal n walca, i klina o. Tak samo mozna zas.apic oba dzwona zebate calkowitemi la- c^acemi -sie z soba kolami zebatemi u, v.Wreszcie dzwignia obciazona Z, zamocowana, w przykladzie, na osi walca sruba zaciskowa W, zostaje przez odsrubowanie tejze obluzo¬ wana, ewent. wylaczona, skutkiem czego nie moize juz wywolywac ruchu powrotnego dol¬ nego walca. Po uskutecznieniu powyzszych manipulacyj maszyna moze pracowac, jak zwykla, obracajaca; sie ruchem ciaglym, wal¬ carka! W razie potrzeby mozna umiescic dzwo¬ na zebate e, f, g, ewent. pierscienie zebate u9 v równiez wewnatrz stojaków c, d. Wów¬ czas pierscienie zebate u, v skladaja sie z dwu pólpierscieni i mocuja na walcach w ten sposób, jak pólpierscieinie q, r, s, t.Próciz tego, naziewnarbriz stojaków na osiach walców, moiznaby umocowac jeszcze jedne walce' czolowe. PLfy & / cb The present invention relates to rolling mills in which the upper roll rotates continuously, while the lower one engages with the upper one only temporarily, and after each rotation of the latter, it automatically returns to its original state. the matrix of both rollers as well as the temporarily engaged toothed bells are interchangeable; said heads can be replaced by rings with impressions placed on the rollers, and the toothed bell by a complete, possibly also a folded gear wheel in several parts. "This improvement to the roll has the effect that one and the same machine can be used once with the lower roll return and another time with the continuous rotation of both rollers, which allows a better, more economical use of the mill. The drawing shows an example of an embodiment of the invention in the form of the invention, namely Fig. 1 of the rollers with continuous rotation from the front, Fig. 2 - these saime rollers in the side view, or in section along the line A-B in Fig. 1, Fig. 3 iA - appropriate rollers in the previous execution with the return movement of the lower roller, after each revolution of the machine. The letters a and b denote the machine rolls placed one above the other in the stands c and d, with the upper roller a rotating; it is constantly being moved by the method. In accordance with the presently common design (Figs. 3 and 4) the upper roll a has two die heads ei /, facing each other diametrically opposite and connected to the die, a gray head is embedded in the lower roll b. shaft c the upper a is equipped with two toothed bells hi? ', seated equally in the' zipede'M 'matrix cover eif, and the lower cylinder b, with a gear bell k, also with the same settlement, in relation to the matrix head g. On the axis of the lower roller b there is a stand on the outside of the stand c a lever with a counterweight l which causes a reverse movement of the roller b after each stroke of the machine. This simple device operates in such a way that during / each rotation in the upper alca and there are two gears, namely the head joint; of the die e, the second time the die head f of the upper roll - from the die head g of the lower roll, and during the entire rotation of the machine, the toothed bell // and k connect both rolls. After each run, as already indicated, the lower roll b returns to its original state under the influence of the counterweight. In the context of the invention, the dies e, /, are mounted interchangeably on the rolls. For this purpose, they are, in the present example, embedded with each of their lower protrusions m in a wedge-shaped longitudinal channel of the roller and fixed with a wedge, after which the matrices can be removed by loosening. The lower roller also has two opposite longitudinal channels n. The toothed bell hik located on the outside of the frame is fixed on the axes of the rollers interchangeably, preventing the threads. for example, two half rings q, and possibly s, t, together forming an impression ring. We fix them on the roller panes of deer, jalk and 1 matrices, namely with the help of the protrusion m, entering into the longitudinal channel n of the cylinder, and the wedge o. u, v. Finally, the load lever Z, which is fixed, in the example, on the axis of the roller, is loosened by unscrewing this, or possibly. deactivated, so that the lower roll can no longer be retracted. After the above manipulations are effective, the machine can run as a normal turning machine; in continuous motion, waltz! If necessary, you can place a toothed bell e, f, g, possibly. Toothed rings u9 v also inside the racks c, d. Then the toothed rings u, v consist of two half rings and are fastened to the rollers in the same way as a half breastplate q, r, s, t. After that, the ribbons of the racks on the roll axes one more face rollers could be attached. PL
