Das bisher übliche Herstellungsverfahren von Bufferkreuzen für Eisenbahnfahrzeuge erfordert umständliche und theureSchmiede- und Schweifsarbeit. Meistens werden die vier Streben einzeln ausgeschmiedet, dann zusammengestellt und mit einer Büchse verschweifst.The previously common manufacturing process of buffer crosses for railway vehicles requires cumbersome and expensive blacksmithing and tailing work. Most often the four struts are individual forged out, then put together and welded with a can.
Bei dem vorliegenden Herstellungsverfahren kommt jedoch die eigentliche Schmiedearbeit ganz in Wegfall.In the present manufacturing process, however, the actual forging work comes entirely in omission.
Der nach dem Profil Fig. 3 gewalzte Träger (Fig. 1) wird in Stücke von entsprechender Länge geschnitten und dann werden die in Fig. 2 schraffirt gezeichneten Theile ausgestanzt oder auf der Heifseisensäge ausgeschnitten. Das so erhaltene Stück rollt man nun um einen Dorn und schweifst dasselbe bei α zusammen. Die Streben oder Füfse werden hierauf nach auswärts gebogen und das fertige Bufferkreuz durch Eindrücken in ein Gesenk (wie. auch bisher üblich) in die endgültige Form gebracht.The beam (Fig. 1) rolled according to the profile of Fig. 3 is cut into pieces of appropriate length and then the parts shown hatched in Fig. 2 are punched out or cut out on a hot iron saw. The piece obtained in this way is now rolled around a mandrel and tied together at α. The struts or feet are then bent outwards and the finished buffer cross is brought into its final shape by pressing it into a die (as was the case up to now).
Die bis jetzt gebräuchlichen Bufferkreuze sind ferner durch das stete Arbeiten der Bufferstangen in den Führungen starkem Verschleifs ausgesetzt, so dafs schon nach verhältnifsmäfsig kurzer Betriebsdauer die Bohrung nachgedreht und ausgebuchst werden mufs.The buffer crosses that have been used up to now are also due to the constant working of the buffer rods exposed to strong wear in the guides, so that afterwards relatively short operating times, the bore must be re-turned and bushed out.
Um auch diesen Uebelstand zu vermeiden und den verschlissenen Theil jederzeit leicht auswechseln zu können, wird das Kreuz nicht mehr geschweifst, sondern erhält die in Fig. 5 angegebene Form. Die geschlossene Verbindung erfolgt durch eine oder mehrere Schrauben b, welche gleichzeitig die auswechselbare Büchse c festhalten.In order to avoid this inconvenience and to be able to easily replace the worn part at any time, the cross is no longer curved, but has the shape shown in FIG. The closed connection is made by one or more screws b, which hold the replaceable sleeve c at the same time.
Ist dann nach einer gewissen Zeit die Bohrung der Büchse durch Verschleifs zu weit geworden, so werden die Schrauben gelöst, die alte Büchse entfernt, die neue eingesetzt und durch Anziehen der Schrauben befestigt.If after a certain time the bore of the bush has become too wide due to wear, so the screws are loosened, the old sleeve removed, the new one inserted and fixed by tightening the screws.
Schliefslich kann auch das Profil des zur Anfertigung der Bufferkreuze erforderlichen Trägers den in Fig. 6 angegebenen Querschnitt erhalten, ohne dafs an dem Verfahren etwas geändert würde.Finally, the profile of the required for the production of the buffer crosses can also be used Carrier obtained the cross-section indicated in Fig. 6, without anything in the process would be changed.
Beim Rollen des die StangenWhen rolling the the poles
führung bildenden Theiles bleiben dann die vier Streben in einer Ebene (Fig. 7) und müssen in die punktirt gezeichnete Lage gebogen werden (Fig. 6).Leading part then remain the four struts in one plane (Fig. 7) and must be bent into the position shown in dotted lines (Fig. 6).
