Description

Hohlniet mit Schließbolzen, dessen Nietschaft sich beim Anziehen des Schließbolzens zu einem flachen, gefalteten Schließkopf-ausbaucht Es sind Hohlniete mit Schließbolzen be- kanntgeworden, bei denen die Schliießkopfbildung durch Anziehen des Bolzens von einer Seite der zu verbindenden Teile aus erfolgt. worauf der Bolzen im Nietschaft belassen wird: Die Aufweitung des Schließkopfes durch den Schließbolzen ist hei einigen dieser bekannten Niete gering, auch wird der Nietkopf in achsiger Richtung nur leicht an den Nietlochrand angedrückt, so daß so erzeugte Hohlniete nur verhältnismäßig schwache, nicht satt anliegende Köpfe besitzen.Hollow rivet with the locking bolt, whose rivet shank bulges closing head-on tightening of the locking bolt into a flat, folded are hollow rivet known become loading with the locking bolt, in which the Schliießkopfbildung which takes place by tightening of the bolt from one side to connecting parts. whereupon the bolt is left in the rivet shank: the expansion of the locking head by the locking bolt is slight with some of these known rivets, and the rivet head is only slightly pressed against the edge of the rivet hole in the axial direction, so that the hollow rivets produced in this way only relatively weak, not tightly fitting heads own.

Bei anderen bekannten Nieten werden die Schließbolzen ganz durch den hohlen Nietschaft hindurchgezogen, wobei aber nur ein wulstförmiger, für hohe Beanspruchung ungeeigneter Schließkopf gebildet wird.In other known rivets, the locking bolts are completely through the hollow rivet shank pulled through, but only a bead-shaped, for high stress unsuitable closing head is formed.

Schließlich sind auch Hohlniete bekannt-.geworden, bei welchen das über das Nietloch herausragende Nietschaftende von dem Kopf (los Schließbolzens doppelt umgelegt und an den Werkstüekrand achsig angepreßt wird. Der Schließbolzen ist dabei von dem Nietschaft getrennt und genau abgedreht. Zum Befestigen des in dem Hohlniet verbleibenden 5chließbolzenteiles wird nach der Schließkopfhildung der Setzkopf auf den mit Rillen verschencn Schaft des Schließbolzens gepreßt. Derartige Niete sind kostspielig und :erfordern einen hohen Setzkopf. Auch schwächt das l?indrehen der Rillen den Querschnitt der Schließbolzen, so daß die übertragbaren Längskräfte beschränkt sind.Finally, hollow rivets have also become known in which the The end of the rivet shaft protruding from the head via the rivet hole (los locking bolt is folded over twice and axially pressed against the edge of the workpiece. The locking bolt is separated from the rivet shaft and turned off precisely. To attach the in The locking bolt part remaining in the hollow rivet is after the closing head formation the setting head is pressed onto the shank of the locking bolt with grooves. Such Rivets are expensive and: require a high setting head. Turning it in also weakens it the grooves the cross-section of the locking bolt, so that the transmissible longitudinal forces are limited.

Die Mängel dieser bekannten Niete werden dadurch behoben, daß erfindungsgemäß der Schließbolzen mit dem den Schließkopf bildenden Ende des Hohlnietes verschweißt ist: Mit dieser Nietausbildung wird ein fester, eng an dem zu verbindenden Werkstück anliegender Schließkopf erreicht. Der Schließbolzen erfordert keine besondere Bearbeitung, ein Verpresscn mit dem Setzkopf ist außerdem unnötig; dieser kann daher niedrig gehalten werden. Wird der Schließkopf finit dem Nietschaft Wasser- bzw. gasdicht verschweißt, so erzielt man hiermit eine vollkommen dichte Nietverbindung.The shortcomings of this known rivet are remedied by the fact that according to the invention the locking bolt is welded to the end of the hollow rivet forming the locking head is: With this rivet design, a solid, close to the workpiece to be connected is achieved adjoining closing head reached. The locking bolt does not require any special processing, In addition, pressing with the setting head is unnecessary; this can therefore be low being held. If the closing head finitely with the rivet shank is water-tight or gas-tight welded, a completely tight rivet connection is achieved.

Auf der Zeichnung sind in Fig. i bis 3 Längsschnitte durch den Hohlniet in den einzelnen Stufen der Nietherstellung dargestellt.On the drawing are in Fig. I to 3 longitudinal sections through the hollow rivet shown in the individual stages of rivet production.

Zum Verbinden z. B. zweier Blechstücke 1 und z wird der Hohlniet a mit dem mit ihm verschweißten Schließbolzen b in das Nietloch eingesetzt. Durch Anziehen des Schließbolzens b (Fig. 2) wird das aus dem Loch herausragende Ende des Nietschaftes zu einem flachen, gefalteten Schließkopf a' ausgebaucht. Der Schließbolzen wird dann, falls notwendig, abgeschnitten (Fig. 3). To connect z. B. two pieces of sheet metal 1 and z, the hollow rivet a is inserted into the rivet hole with the locking bolt b welded to it. By tightening the locking bolt b (FIG. 2), the end of the rivet shaft protruding from the hole is bulged into a flat, folded locking head a '. The locking bolt is then cut off if necessary (Fig. 3).
