Description
Einrichtung bei Verbindungen von dicken Blechen zum Prüfen ihrer Dichtheit. Gegenstand der Erfindung des Haupt patentes ist eine Einrichtung bei Blechver bindungen, bei welchen die miteinander ver bundenen Bleche einen Zwischenraum ein schliessen, in den zum Prüfen der Dichtheit der Verbindung Druckflüssigkeit hineingepresst werden kann. Gegenstand vorliegender Er findung ist eine Einrichtung bei Verbindungen von dicken Blechen zum Prüfen ihrer Dicht heit, gemäss der Erfindung sind die Bleche durch Überblattung miteinander verbunden und der Zwischenraum zum Prüfen der Dicht heit der Verbindung ist in mindestens einem Blatt ausgespart.
Auf der Zeichnung sind als Ausführungs beispiele des Erfindungsgegenstandes einige Blechverbindungen im Schnitt zur Darstellung gebracht.
a und b sind die miteinander verbundenen Bleche. Die Blechränder sind durch Über- blattung zum Übergreifen gebracht und durch Versehweissungen c an den Blatträndern c miteinander verbunden. Zum Prüfen der Dichtheit der Verbindung ist in den Blättern d 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 Fig. 3 und 4 gezeigt, oder durch Aussparen beider Blätter, wie in Fig. 1, 2, 5 und 6 gezeigt, entstehen; natürlich sind auch noch andere Profile als die gezeichneten möglich. Das Druckmittel wird durch die Öffnung f in den Hohlraum eingeführt. Mit einer der artigen Verbindung wird das besonders bei dicken Blechen sehr schwierige Einbrödeln eines Hohlraumes in den Blechrand ver mieden.
Device for joining thick metal sheets to check their tightness. The subject of the invention of the main patent is a device in Blechver connections, in which the interconnected sheets include a space into which hydraulic fluid can be pressed to check the tightness of the connection. The present invention is a device for connections of thick sheets to test their tightness, according to the invention, the sheets are connected by overlapping and the space to test the tightness of the connection is cut out in at least one sheet.
In the drawing, some sheet metal connections are shown in section as execution examples of the subject invention.
a and b are the sheets connected to one another. The sheet metal edges are made to overlap by overlapping and connected to one another by welded joints c on the sheet edges c. To check the tightness of the connection, a cavity e is cut out in the leaves d, which is best produced by planing the sheet metal edges when the sheet metal is flat.
The cavity can either be created by cutting out only one sheet, as shown in FIGS. 3 and 4, or by cutting out both sheets, as shown in FIGS. 1, 2, 5 and 6; Of course, other profiles than those shown are also possible. The pressure medium is introduced into the cavity through the opening f. With such a connection, the crumbling of a cavity into the edge of the sheet, which is very difficult, especially with thick sheets, is avoided.
