KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. und ähnliche Teile.and similar parts. Das Befestigen von Metallringen in den Gehäusen von Dampf- und Wasserschieberventilen und den dazu gehörigen Dichtungskeilen o. dgl. wurde bisher nur durch Einhämmern bewirkt. Der betreffende Körper wurde aufgespannt, eingedreht, dann von der Drehbank abgespannt und die Ringe festgehämmert, um dann nochmals aufgespannt und fertiggedreht zu werden. Durch den Walzapparat nach vorliegender Erfindung ist der schon lange gesuchte Vorteil geschaffen, daß ein Körper bei nur einmaligem Aufspannen mit Rillen versehen, die Ringe festgewalzt und fertiggedreht werden können, und daher das öftere Auf- und Abspannen wegfällt. Ein anderer Vorteil in dem Einwalzen statt Einhämmern der Ringe . besteht in einer ganz bedeutenden Metallersparnis. Durch das Einwalzen wird nämlich eine gerade glatte Fläche erzielt, welche sehr leicht durch einen feinen Span sauber zu drehen ist, hingegen entstehen durch das Einhämmern tiefe Beulen in den Ringen, die Dichtfläche ist nur durch mehrmaliges Abdrehen sauber zu bringen, und es müssen die Ringe demnach im Rohguß nicht nur bedeutend dicker sein, sondern das Metall ist auch sehr leicht der Gefahr ausgesetzt, durch vieles Hämmern rissig und dadurch unbrauchbar zu werden.The fastening of metal rings in the housings of steam and water slide valves and the associated sealing wedges o. The like. Has so far only been effected by hammering. The body in question was clamped, turned in, then tensioned from the lathe and the rings are hammered into place, only to be stretched and finished turning. By the rolling apparatus according to the present Invention, the long-sought advantage is created that a body at Provided with grooves only once clamping, the rings rolled down and finished turned can be, and therefore the frequent tensioning and unclamping is no longer necessary. Another advantage in rolling in instead of hammering in the rings. consists in a very significant metal saving. By rolling in, a straight, smooth surface is achieved, which can be easily cleaned with a fine chip turning, while hammering in causes deep dents in the rings, which The sealing surface can only be brought clean by twisting it off several times, and the Rings are therefore not only significantly thicker in the raw casting, but the metal is also very easily exposed to the risk of through a lot of hammering to become cracked and useless. Der Apparat besteht aus dem Stahlkörper a, dem äußeren Ring b, den Rollen c, den Schrauben d und dem Halter e. The apparatus consists of the steel body a, the outer ring b, the rollers c, the screws d and the holder e. Die Eindrehung des Werkstückes zur Aufnahme des Metallringes wird durch -einen in den Stahlkörper α einzuführenden Fassonstahl bewirkt. Nach Entfernung des letzteren wird der wie Fig. 1 gedrehte Metallring' auf folgende Art festgewalzt:The turning of the workpiece to accommodate the metal ring is effected by a shaped steel to be introduced into the steel body α. After removing the latter, the metal ring turned as in Fig. 1 is rolled down in the following way: Der im Support der Drehbank eingespannte Halter e drückt den Körper α mit den in ihm befindlichen Rollen c gegen den in drehender Bewegung befindlichen Metallring, dadurch nimmt dieser die in Fig. 2 dargestellte Form an. The holder e clamped in the support of the lathe presses the body α with the rollers c located in it against the rotating metal ring, which takes on the shape shown in FIG. Um dabei das Material des Ringes in die unterschnittene Nut des Schiebers zu drängen, sind die Wälzen mit schraubengangartigen Eindrehungen auf ihrem Umfange versehen.In order to push the material of the ring into the undercut groove of the slide, the rollers are provided with helical indentations on their circumference.
