Description

Blechverbindung zur Ermöglichung von Dichtigkeitsproben Die Erfindung betrifft eine Einrichtung zur Ermöglichung von Dichtigkeitsproben bei Blechverbindungen nach Patent 450941 in Anwendung auf dicke Bleche und besteht darin, daß die Bleche durch überblattung miteinander verbunden sind und der Zwischenraum zum Prüfen der Dichtheit der Verbindung in den Blättern, mindestens jedoch in einem Blatt, ausgespart ist. Durch diese Ausbildung wird bezweckt, bei dicken Blechen eine Umbördelung des Blechrandes zu vermeiden.Sheet metal connection to enable leak tests. The invention relates to a device for enabling leak tests with sheet metal connections according to patent 450941 in application to thick sheets and consists in that the sheets are connected by overlapping and the space for checking the Tightness of the connection in the leaves, but at least in one leaf is. The purpose of this training is to flanging the thick sheet metal To avoid the edge of the sheet.

Auf der Zeichnung sind als Ausführungsbeispiele des Erfindungsgegenstandes einige Blechverbindungen im Schnitt dargestellt.The drawing shows exemplary embodiments of the subject matter of the invention some sheet metal connections shown in section.

a und b sind die miteinander verbundenen Bleche. Die Blechränder sind durch überblattung zum Übergreifen gebracht und durch Verschweißung der Blattränder c mit dem Gegenstück verbunden. a and b are the sheets connected to one another. The sheet edges are made to overlap by lapping and connected to the counterpart by welding the sheet edges c.

Zum Prüfen der Dichtigkeit der Verbindung ist in den Blätternd ein Hohlraum e ausgespart, der am besten durch entsprechendes Hobeln der Blechränder im flachen Zustand des Bleches hergestellt wird. Der Hohlraum kann entweder durch Aussparen nur des einen Blattes, wie in Abb. 3 und 4 gezeigt, oder durch Aussparen beider Blätter, wie in Abb. I, 2, 5 und 6 gezeigt, entstehen, wobei natürlich auch noch andere Profile als die gezeichneten möglich sind. Das Druckmittel wird durch die öffnung f in den Hohlraum eingeführt.To check the tightness of the connection is in the sheets Recessed cavity e, which is best done by planing the sheet metal edges accordingly is made in the flat state of the sheet. The cavity can either go through Cut out only one sheet, as shown in Figs. 3 and 4, or by cutting out both leaves, as shown in Fig. 1, 2, 5 and 6, arise, of course also Profiles other than those shown are also possible. The pressure medium is through the opening f is introduced into the cavity.

Mit einer derartigen Verbindung wird das besonders bei dicken Blechen sehr schwierige Einbördeln eines Hohlraumes in dem Blechrand vermieden.With such a connection, this is particularly important with thick metal sheets very difficult crimping of a cavity in the sheet metal edge avoided.
