Description

. Die Erfindung bezieht sich auf ein Verfahren zum Verbinden von Blechen, insbesondere dünner Bleche.. The invention relates to a method for joining metal sheets, especially thin sheets.

Bleche werden im allgemeinen durch Nieten oder Punktschweißen miteinander verbunden: Nieten hat für kleinere Hohlkörper den Nachteil, daß das Bohren oder Stanzen der Löcher; das Einbringen der Nieten und das Stauchen der Nieten nicht in einem Arbeitsgang' durchgeführt werden kann, so daß es für solche Zwecke zu zeitraubend und zu teuer ist. Beim Punktschweißen von Blechen besteht die Gefahr; daß entweder Löcher in die Bleche gebrannt werden oder daß die Verbindungen infolge des Zunders sich schon bei verhältnismäßig geringer Beanspruchung wieder lösen.Sheets are generally joined together by riveting or spot welding connected: riveting has the disadvantage for smaller hollow bodies that drilling or Punching the holes; inserting the rivets and upsetting the rivets are not can be carried out in one operation, so that it is too time-consuming for such purposes and is too expensive. There is a risk of spot welding sheet metal; that either Holes are burned in the sheet metal or that the connections are a result of the scale can be released again with relatively little stress.

Es ist bekannt, Bleche dadurch miteinander zu verbinden, daß aus den beiden fest -aufeinander liegenden Blechen übereinanderliegende gleichbleibende Streifen in derselben Richtung herausgedrückt werden. Hierbei erfolgt eine erheblich über die Blechstärke herausgehende Verformung der herausgedrückten Blechstreifen, und die dadurch hervorgerufene Verbindung ist nur eine sehr unvollkommene.It is known to connect sheets together that from the two fixed sheets lying one on top of the other, one on top of the other Be pushed out in the same direction. A considerable amount occurs here Deformation of the pressed out sheet metal strips beyond the sheet thickness, and the connection it creates is only a very imperfect one.

Den Gegenstand der Erfindung bildet nun ein Verfahren zum Verbinden von Blechen, das zwar die Vorteile der beiden vorgenannten Verfahren in sich vereint, ihre Nachteile aber vollkommen vermeidet.The subject of the invention now forms a method for connecting of sheet metal, which combines the advantages of the two aforementioned processes, but completely avoids their disadvantages.

Das Verfahren nach der Erfindung besteht darin, daß aus den beiden fest aufeinander liegenden Blechen übereinanderliegende gleichbreite Streifen in derselben Richtung so weit herausgedrückt werden, daß die Unterseite des unteren Streifens mit der Oberseite des oberen Bleches in gleicher Höhe liegt und dann entweder der untere Streifen durch Pressen beiderseitig so weit verbreitert wird, daß er in die Schlitze des oberen Bleches hineinragt, oder das Loch im oberen Blech durch Pressen der Längskanten nach innen verengt wird. Hierbei ist angenommen, daß das Werkzeug von unten nach oben arbeitet, was selbstverständlich auch in umgekehrter Richtung geschehen kann.The method according to the invention consists in that of the two sheets of sheet metal lying firmly on top of one another in in the same direction so far that the underside of the lower Strip is level with the top of the top sheet and then either the lower strip is widened so far by pressing on both sides that it protrudes into the slots in the upper plate, or through the hole in the upper plate Pressing the longitudinal edges is narrowed inwards. It is assumed here that the The tool works from bottom to top, which of course also works in reverse Direction can happen.

Je nach der auftretenden Beanspruchung können auch mehrere derartige Verbindungsstellen nebeneinander angeordnet werden.Depending on the stress that occurs, several of these can also be used Connection points are arranged side by side.

An Hand der Zeichnung soll das erfindungsgemäße Verfahren näher erläutert werden.The method according to the invention is to be explained in more detail with reference to the drawing will.

Fig. i zeigt die beiden aufeinanderliegenden Bleche i und 2:. Durch Druck eines Stempels von unten her sind zwei Blechstreifen 3 und 4 brückenartig nach oben aus dem Blech herausgedrückt. Dann wird durch Pressen der untere Streifen 3 an seinen Längskanten um die Flächen 5 verbreitert, wie es in Fig. z dargestellt ist, oder es wird gemäß Fig. 3 das Loch im oberen Blech :2 um die Flächen 6 eingeengt. Die strichpunktierten Linien zeigen in Fig. 2 und 3 die Lage der Längskanten vor der Deformierung.Fig. I shows the two superimposed sheets i and 2 :. By When a stamp is printed from below, two metal strips 3 and 4 are like a bridge pushed out of the sheet metal upwards. Then press the lower strip 3 widened at its longitudinal edges by the surfaces 5, as shown in FIG or the hole in the upper plate: 2 is narrowed around the surfaces 6 as shown in FIG. The dash-dotted lines in Fig. 2 and 3 show the position of the longitudinal edges the deformation.
