Verfahren zur Herstellung von Röhrenapparaten.Process for the manufacture of tube apparatus.
Patentiert im Deutschen Reiche vom 8. März 1905 ab.Patented in the German Empire on March 8, 1905.
Der Gegenstand der Erfindung betrifft Neuerungen in dem Verfahren zur Herstellung von Röhrenapparaten, wie Kühlern, Kondensatoren, Heizkörpern und Kesseln durch Umgießen der Enden der zu einem Block zusammengesetzten und in die Gußform in einem bestimmten Abstand vom Boden der Gußform eingesetzten Hohlelemente.The subject matter of the invention relates to innovations in the method of manufacture of tube apparatus such as coolers, condensers, radiators and boilers by casting around them the ends of the assembled into a block and into the mold at a certain distance from the bottom of the mold inserted hollow elements.
Bei der Herstellung solcher aneinandergereihten Elemente, wie z. B. bei hohlbandförmigen flachen Messingrohren für Kühler, erhält man durch das Zugießen der Enden nach der Erfindung zugleich mit der Kopfplatte das Zu- und Abflußgefäß für das kühlende bzw. zu beheizende Mittel, wenn man die einzelnen Hohlelemente miteinander durch seitliche öffnungen bzw. Durchbohrungen verbindet oder gleich Zu- und Abflußgefäß mitangießt, so daß das Anschließen solcher Zu- und Abflußgefäße durch Anschrauben, Anlöten o. dgl. Mittel vermieden wird. Damit sämtliche Elemente, welche an den Kopfenden geschlossen sind, miteinander verbunden sind, kann man dies durch Bohren von der Seite her quer durch die untersten Teile der Kopfenden bewirken oder auch unter Umständen durch Drehen, Hobeln, Sägen o. dgl. die unteren Enden der Rohre wieder freilegen.In the production of such lined up elements, such as. B. with hollow belt-shaped Flat brass tubes for radiators are obtained by casting the ends according to the invention at the same time as the top plate the inflow and outflow vessel for the cooling or heating medium, if the individual hollow elements are connected to one another through lateral openings or through bores, or connects the inlet and outlet vessels pours, so that such inflow and outflow vessels can be connected by screwing on, Soldering or similar means is avoided. So that all elements, which are closed at the head ends, with each other are connected, you can do this by drilling from the side across the bottom Part of the head ends or, under certain circumstances, by turning, planing, sawing or the like. Uncover the lower ends of the tubes again.
Andererseits kann man aber auch durch Benutzung mehrteiliger, oben offener Gußformen ohne weiteres besondere Hohlgefäße beim Angießen der Kopfplatten zugleich mitangießen. On the other hand, you can also use multi-part, open-top molds Without further ado, special hollow vessels should be poured onto the top plates at the same time.
Beim Angießen der geschlossenen Kopfplatten verfährt man folgendermaßen: When casting on the closed head plates, proceed as follows:
Die nebeneinandergestellten Hohlelemente werden nicht bis auf den Boden der Gießplatte herabgesetzt, sondern so in den Gießrahmen eingebracht, daß ihre Enden noch einen bestimmten Abstand von der Gießfläche j haben. ■ ·The juxtaposed hollow elements are not down to the bottom of the casting plate reduced, but so introduced into the casting frame that their ends are still a certain distance from the casting surface j have. ■ ·
Schwieriger gestaltet sich das Verfahren, wenn man die gegossenen Kopfplatten gleich zu Hohlgefäßen für Zu- und Abfluß des durchströmenden Mittels ausgestalten will. In diesem Falle müssen entsprechende zwei- oder mehr als zweiteilige Gußformen benutzt werden. Die Hauptschwierigkeit liegt in diesem Falle darin, genügend schwache Wandungen für das Kopfgefäß zu erhalten. Es können daher nur verhältnismäßig dünnflüssige und dichten Guß ergebende Metalle oder Legierungen benutzt werden.The process is more difficult if the cast head plates are the same wants to design hollow vessels for the inflow and outflow of the medium flowing through. In in this case, corresponding two-part or more than two-part molds must be used. The main difficulty in this case is to obtain sufficiently weak walls for the head vessel. It can therefore only relatively thin and dense cast metals or alloys to be used.
Fig. ι und 2 stellen eine durch Gießen vereinigte Batterie von zylindrischen Röhren dar. Fig. 2 ist Schnitt A-B der Fig. 1. Die einzelnen Röhren α haben durch Gießen die Kopfplatten c, c erhalten, um die noch die Gießrahmen b, b liegen.1 and 2 represent a battery of cylindrical tubes combined by casting. FIG. 2 is section AB of FIG. 1. The individual tubes α have received the top plates c, c by casting, around which the casting frames b, b are still located .
Statt runder Röhren kann man auch andere Hohlkörper beliebigen Querschnitts, z. B. ovalen Querschnitts, wie Fig. 3 andeutet, benutzen; insbesondere wird man zur Erzielung großer Kühl- oder Heizfläche profilierte Röhren, wie solche jetzt vielfach hergestellt werden, oder Hohlkästen aus glattem oder aus Wellblech benutzen.Instead of round tubes, you can also use other hollow bodies of any cross-section, e.g. B. oval Use cross-section, as Fig. 3 indicates; in particular, one is going to achieve great Tubes profiled for cooling or heating, as are now often produced, or Use hollow boxes made of smooth or corrugated sheet metal.
