Description

Die Erfindung betrifft die Lösung -der Aufgabe, durch sparlose Formung die form- und kraftschlüssige Verbindung eines Hohlkörpers aus Metallblech, vorzugsweise eines Stahlrohrs, mit einem an dessen Innen- oder Außenwand anliegenden Füllstück herzustellen. Die Verbindung soll wesentlich fester sein, als sie durch lehrerhaltigen Paßsitz, z. B. Preßsitz, erreicht werden kann, während außerdem die Bedingung gestellt ist, daß die auf dem und im Füllstück befindlichen Teile des hohlen Blechkörpers nicht bearbeitet sein sollen.The invention relates to the solution of the task by economical shaping the positive and non-positive connection of a hollow body made of sheet metal, preferably a steel pipe, with a filler piece resting against its inner or outer wall to manufacture. The connection should be much stronger than it is through the teacher Snug fit, e.g. B. interference fit, can be achieved while also making the condition is that the parts of the hollow sheet metal body located on and in the filler piece should not be processed.

In der Zeichnung ist die Erfindung an Hand eines Ausführungsbeispiels dargestellt. , Fig. i ist die Seitenansicht der fertigen Verbindung; Fig. a ist ein Schnitt nach Linie II-II der Fig. i; Fig. 3 und q. zeigen Einzelheiten in vergrößertem Maßstab; aus Fig. j, 6, 7 geht die Stufenfolge der hauptsächlichen Verfahrensschritte hervor.In the drawing, the invention is based on an exemplary embodiment shown. Fig. I is the side view of the completed joint; Fig. A is a section along line II-II of Fig. i; Fig. 3 and q. show details in enlarged Scale; j, 6, 7 shows the sequence of the main process steps emerged.

Die durch sparlose Formung erreichte Verbindung eines in einem Rohr i eingesetzten Füllstükkes z wird danach auf folgende Weise erreicht: Das Füllstück 2 erhält eine Eindrehung 3 von rechteckigem Querschnitt. In diese Eindrehung wird Werkstoff des Rohres in Form einer nach innen gerichteten Sicke q. eingepreßt oder eingewalzt. An geeigneten, etwa einander gegenüberliegenden Stellen wird die Sicke glattgedrückt, wobei die Randpartien 6 eingeschert werden. Bei diesem Vorgang wird durch Strecken der vorherigen Wölbung der Werkstoff gegen die Ränder 7 der Eindrehung 3 gepreßt und somit ein fester Halt des Füllstückes im Rohr unter Form- und Kraftschluß erreicht.The connection of one in a pipe achieved through economical shaping i inserted filler piece z is then achieved in the following way: The filler piece 2 receives a recess 3 with a rectangular cross-section. In this turning is Material of the pipe in the form of an inwardly directed bead q. pressed in or rolled in. The bead is at suitable, approximately opposite points pressed flat, the edge portions 6 being reeved. During this process, by stretching the previous curvature of the material against the edges 7 of the recess 3 pressed and thus a firm hold of the filler in the pipe with form and force fit achieved.

Die in der Zeichnung dargestellten kleinen Bohrungen 8 werden angewendet, um die Einscherungsstelle einwandfrei abzugrenzen. Sie sind nicht unbedingt erforderlich.The small holes 8 shown in the drawing are used in order to clearly delimit the place of reeving. They are not absolutely necessary.

Die form- und kraftschlüssige Verbindung kann nach dem Verfahren für die Verbindung von Füllstücken mit Blechrohren von beliebiger Länge und von beliebigem Querschnitt angewendet werden. Wenn diese Verbindung auch für geschlossene Profile besonders vorteilhaft ist, so zeigt sich ihr Nutzen in einem gewissen Grade auch bei geschlitzten Profilen. Ein wesentlicher Vorteil liegt ferner darin, daß weder das Blech noch das daran zu befestigende Füllstück paßgerecht zu sein braucht, noch einer besonderen Vorarbeit bedarf.The form-fitting and force-fitting connection can according to the method for the connection of filler pieces with sheet metal pipes of any length and any Cross-section can be applied. If this connection also for closed profiles If it is particularly advantageous, its utility also shows itself to a certain extent with slotted profiles. Another major advantage is that neither the sheet metal still needs to be properly fitted with the filler piece to be attached to it requires special preparatory work.

Das Verfahren kann auch mit Nutzen verwendet werden, um zwei Hohlkörper z. B. gleichachsig ineinander zu befestigen und durch Verbindungsstücke als Abstandhalter in ihrer Lage gegeneinander zu sichern, die in diesem Fall' innen und außen mit Eindrehungen versehene Ringkörper sind. Das Verfahren wird in solchen Fällen zweimal nacheinander angewendet. Von Nutzen kann schließlich das Verfahren auch sein, um Verstärkungsstücke, Ansätze od. dgl. außen auf Hohlrohren anzubringen.The method can also be used with benefit to two hollow bodies z. B. to fasten coaxially into each other and by connecting pieces as spacers in their position to secure against each other, in this case 'inside and outside with Annular bodies provided with indentations are. The procedure is twice in such cases applied one after the other. Finally, the procedure can also be of use in order to Reinforcement pieces, approaches or the like to be attached to the outside of hollow tubes.
