Description
Richtrolle für flachgewalzte, bezw. flachgezogene 1VIetalldrähte. Zum Geraderichten flachgewalzter bezw. flachgezogener Metalldrähte, zum Beispiel solcher für Blattzähne, verwendet man zuein ander versetzte und regelbar gegeneinander gepresste, um eine vertikale Axe drehbare Richtrollen 1 (Fig. 1) mit Umfangsrinne 2, wobei der zu richtende, flach gewalzte Me talldraht \3' in diesen Rinnen zwischen den Richtrollen hindurchgezogen und hierdurch geradegerichtet -wird.
Das Einstechen der Riemen in die Richt- rollen bietet nun in anbetracht der sehr kleinen Breite derselben (0,1 bis 0,5 mm) er hebliche Schwierigkeiten. Ein anderer Übel stand der bisher üblichen Rollen liegt darin, dass die zu richtenden flachgewalzten Metall drähte den Grund der Rinnen der Richtrollen stark abnützen und so nach Abnutzung einer Rinne gleich die ganze Rolle ausgeschaltet werden muss, was einen starken Materialver schleiss und Arbeitsverlust hervorruft.
Diese Nachteile werden bei der den Gegenstand der vorliegenden Erfindung bil denden Richtrolle für flachgewalzte bezw. flachgezogene Metalldrähte dadurch besei tigt, dass die Rinne der Rolle durch zwei axial relativ zueinander bewegliche, die Sei tenwände der Rinne bildende. zylindrische Teile und einen in den einen dieser Teile aus wechselbar eingesetzten, den Grund der Rinne bildenden Ring aus hartem Material gebildet wird.
In der Zeichnung sind durch Fig. 2 und 3 zwei Ausführungsbeispiele des Erfin dungsgegenstandes im Axialschnitt darge stellt; Fig. 4 ist ein Grundriss zu Fig. 3.
Beim Beispiel nach Fig. 2 bezeichnet 4 ei nen zylindrischen, axial durchbohrten Teil mit Flansche 5, in welche eine Vertiefung 6 eingedreht ist. In dieseVertiefung ist ein Ring 7 aus hartem Material, zum Beispiel Hart bronze, Glas etc., unbeweglich, aber auswech selbar eingesetzt. Auf den mit Aussenge winde 8 versehenen zylindrischen Teil 4 ist ein ebenfalls zylindrischer, ringförmiger Teil 9 mit Aussparung 10 zur Aufnahme des obern Teils des Ringes 7 geschraubt und durch eine Stellschraube 11 am Teil 4 ge sichert.
Die einander zugekehrten schmalen Randflächen 12 und 13 der Teile 4 und 9 bilden nun die Seitenwandungen der Richt- rinnen und die Aussenwand des Ringes 7 den Grund derselben. Durclh Höher- oder Tiefer schrauben des Ringteils 9 kann die Breite der Richtrinne bestimmt werden. In der ein gestellten Lage wird der Ring 9 durch die Schraube 11 bleibend festgestellt.
Der Ring 7 nützt sich infolge seiner Härte nur sehr wenig ab und kann nötigenfalls leicht ausgewechselt werden.
Beim Beispel nach Fig. 3 und 4 ist der zylindrische Teil 41 der Richtrolle länger als in Fig. 2 und trägt eine Schraubenmutter 14, mittelst welcher der gegenüber Fig. 2 eben- falls länger ringzylindrische Teil 91 gegen den Teil 41 bewe(rt werden kann. Eine zwischen dem Ring 7^und dem Boden des Teils 9' eingesetzte Feder 15 ist bestrebt, den Teil 91 vom Teil 41 wegzubewegen lind an die Mutter 14 zu pressen.
Durch die Mutter 14 kann nun die Breite der Richtrinne ent sprechend der Dicke des geradezurichtenden, flachgewalzten Metalldrahtes 3 verändert werden, wobei eine an der obern Fläche der 'Mutter 14 (Fig. 4) vorgesehene Skala 16 zusammen mit einer auf der obern Rand fläche des Teils 41 angebrachten Strichmarke 17 Breitenänderungen der Rinne in Zehntels- iTillimeter anzeigt. Ein Querstift 18 des Teils 4' greift in eine Nut 19 des Teils 91 und nimmt letztere bei der Drehung mit.
Straightening roll for flat-rolled, resp. Flat-drawn 1V metal wires. For straightening flat-rolled or Flat-drawn metal wires, for example those for blade teeth, are used to one another offset and controllably pressed against each other, about a vertical axis rotatable straightening rollers 1 (Fig. 1) with circumferential groove 2, the to be straightened, flat-rolled Me talldraht \ 3 'in these grooves is pulled through between the straightening rollers and thereby straightened.
In view of the very small width of the belts (0.1 to 0.5 mm), piercing the belts into the straightening rollers presents considerable difficulties. Another problem with the roles that have been customary up to now is that the flat-rolled metal wires to be straightened wear down the bottom of the grooves of the straightening rolls and so the entire roll has to be switched off immediately after one groove has been worn, which causes heavy material wear and loss of work.
These disadvantages are in the bil Denden straightening roller for flat rolled BEZW. Flat-drawn metal wires are eliminated by the fact that the channel of the roller is formed by two axially relative to one another, which form the side walls of the channel. cylindrical parts and one in one of these parts from replaceably inserted, the bottom of the channel forming ring is formed from hard material.
In the drawing, two embodiments of the invention are in axial section through Fig. 2 and 3 provides Darge; FIG. 4 is a plan view of FIG. 3.
In the example of FIG. 2, 4 denotes a cylindrical, axially pierced part with flanges 5 into which a recess 6 is screwed. A ring 7 made of hard material, for example hard bronze, glass, etc., is inserted immovably into this recess but can be replaced. On the threaded with Aussenge 8 cylindrical part 4 is also a cylindrical, annular part 9 screwed with recess 10 for receiving the upper part of the ring 7 and secured by a screw 11 on part 4 ge.
The mutually facing narrow edge surfaces 12 and 13 of the parts 4 and 9 now form the side walls of the straightening channels and the outer wall of the ring 7 the base of the same. By screwing the ring part 9 higher or lower, the width of the straightening channel can be determined. In the one set position, the ring 9 is permanently determined by the screw 11.
The ring 7 wears only very little due to its hardness and can easily be replaced if necessary.
In the example according to FIGS. 3 and 4, the cylindrical part 41 of the straightening roller is longer than in FIG. 2 and carries a screw nut 14 by means of which the annular cylindrical part 91, which is also longer than in FIG. 2, can be moved against the part 41 A spring 15 inserted between the ring 7 ^ and the bottom of the part 9 'tries to move the part 91 away from the part 41 and to press it against the nut 14.
Through the nut 14, the width of the straightening channel can be changed accordingly to the thickness of the straightened, flat-rolled metal wire 3, with a on the upper surface of the 'nut 14 (Fig. 4) provided scale 16 together with a surface on the upper edge of the Partly 41 attached line mark 17 shows changes in width of the channel in tenths of a millimeter. A transverse pin 18 of part 4 'engages in a groove 19 of part 91 and takes the latter with it when it rotates.
