gezeichneten Stellung hat die dem Nietschaftende gegenüberliegende Widerlagerfläehe die weiteste Entfernung von der Nietstelle. Durch Drehen des Werkzeuges in dem einen oder anderen Sinne wird der Abstand von der Nietstelle verringert.
Nach der Fig. 4 besteht das Werkzeug aus zwei Hauptteilen, dem Amboss 5 und dem gegen die Rohrwand sich stützenden Teil 6. Ersterer wird an einer Drehung verhindert, während der mit ihm ge- lenkig verbundene. als Exzenter ausgebildete Teil 6 während des Nietens in der Pfeilrichtung gedreht wird. wodurch der Amboss J senkrecht gegen die Nietstelle-in der Richtung des geraden Pfeiles-vor-
EMI2.1
gegen Drehung gesichert werden : das Drehen des Widerlagerteiles kann durch eine gleichfalls nach aussen führende Stange 1. J. geschehen. Einzelheiten dieser Festhalte-und Drehvorriehtung sind in der Fig. 6 dargestellt.
Nach Fig. 5, a a und fi besteht das Werkzeug gleichfalls aus zwei Hauptteilen, dem Amboss 5
EMI2.2
welche miteinander gelenkig verbunden sind. Wird beispielsweise bei der Anfangsstellung der Exzenter nach Fig. Ï der Teil 5 an einer Drehung verhindert und der Teil 6 in Pfeilrichtung gedreht, so wird sich der Teil 5, wie bei Fig. 4. senkrecht in Richtung des geraden Pfeiles gegen den Nietort hin verschieben. Eben- - ogut kann auch. wenn die Exzenterstellung zu Beginn des Nietens gemäss Fig. Ï a gewählt wird, der Teil 6 gegen Drehung gesichert und der Teil J im Pfeilsinne gedreht werden, wodurch sich dann eine Wirkung ähnlich wie in Fig. 2 oder 3 ergibt. Endlich können auch beide Teile 5 und 6 während des Nietvorganges gleichzeitig Drehbewegung erfahren.
Die Teile J und 6 können bei dieser Anordnung hinsichtlich ihrer Funktion als Amboss und als Abstützung gegen die Rohrwand beliebig miteinander vertauscht werden.
Zur Verhinderung oder zur Erzeugung einer Drehbewegung der einzelnen Teile ist der Teil 6 mit
EMI2.3
unter die Nietstelle zu liegen kommt.
PATENT-ANSPRA'HE :
1. Verfahren zur Herstellung von Nietverbindungen in den Wandungen von Hohlkörpern u. dgl., deren Inneres mit Nietwerkzeugen schwer zugänglich ist. dadurch gekennzeichnet, dass der Schliesskopf des Nietes auf der schwer zugänglichen Seite in der Weise gebildet wird. dass der Niet von der leicht zugänglichen Seite her gegen ein auf der schwer zugang-eigen Seite befindliches, verschiebbares Widerlager ge@chlagen wird. während gleichzeitig der Abstand des Widerlagers von der den Niet aufnehmenden
Wand ständig von der ursprünglichen frei vorragenden Nietsehaftlänge bis zur Dicke des Schliesskopfes verringert wird.

The abutment surface opposite the end of the rivet shaft has the farthest distance from the rivet point. By turning the tool in one direction or another, the distance from the riveting point is reduced.
According to FIG. 4, the tool consists of two main parts, the anvil 5 and the part 6 that is supported against the pipe wall. The former is prevented from rotating, while the one hinged to it. formed as an eccentric part 6 is rotated during riveting in the direction of the arrow. whereby the anvil J is perpendicular to the riveting point - in the direction of the straight arrow -
EMI2.1
be secured against rotation: the rotation of the abutment part can be done by a rod 1, which also leads outwards. Details of this retaining and rotating device are shown in FIG.
According to FIG. 5, a a and fi, the tool also consists of two main parts, the anvil 5
EMI2.2
which are hinged to each other. If, for example, in the initial position of the eccentric according to FIG. Ï, part 5 is prevented from rotating and part 6 is rotated in the direction of the arrow, then part 5, as in FIG. 4, will move vertically in the direction of the straight arrow towards the rivet location . Even - o good can too. If the eccentric position is selected at the beginning of the riveting according to FIG. Ï a, the part 6 is secured against rotation and the part J is rotated in the direction of the arrow, which then results in an effect similar to that in FIG. 2 or 3. Finally, both parts 5 and 6 can simultaneously experience rotary motion during the riveting process.
In this arrangement, the parts J and 6 can be interchanged with one another as desired with regard to their function as an anvil and as a support against the pipe wall.
To prevent or to generate a rotary movement of the individual parts, the part 6 is with
EMI2.3
comes to lie under the riveting point.
PATENT APPROACH:
1. A method for producing riveted joints in the walls of hollow bodies and. Like. The interior of which is difficult to access with riveting tools. characterized in that the closing head of the rivet is formed on the hard-to-reach side in this way. that the rivet is hit from the easily accessible side against a movable abutment located on the difficult-to-access side. while at the same time the distance between the abutment and the one receiving the rivet
Wall is continuously reduced from the original freely protruding rivet shaft length to the thickness of the closing head.
