KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Nietgegenhalter gemäß vorliegender Erfindung wird durch Luftdruck o. dgl. in die Arbeitsstellung gebracht. Er unterscheidet sich von den bisher bekannt gewordenen dadurch, daß eine durch Druckluft bewegte Flüssigkeit (Öl ο. dgl.), nachdem sie den Kolben b mit dem Stempel d gegen den zu schließenden Niet vorgeschoben hat, in dem Zylinder dieses Kolbens eingeschlossen wird,The rivet backstop according to the present invention is brought into the working position by air pressure or the like. It differs from the previously known ones in that a fluid (oil, etc.) moved by compressed air, after it has pushed the piston b with the punch d against the rivet to be closed, is enclosed in the cylinder of this piston,
ίο wodurch sie den Schlägen bei der Bildung des Schließkopfes einen weniger elastischen Widerstand bietet als die Druckluft bei den bekannten pneumatischen Gegenhaltern.ίο thereby giving them the blows in the formation of the closing head offers a less elastic resistance than the compressed air in the known pneumatic counterholders.
Die Zeichnung zeigt den neuen Gegenhalter im Längsschnitt und läßt seine Wirkungsweise erkennen.The drawing shows the new counter holder in longitudinal section and leaves its mode of operation recognize.
Druckluft tritt in den Kanal 1 des Hahnes a 'ein und gelangt in der gezeichneten Stellung in die Kanäle 2 und 3 und von da hinter den Kolben c, den sie vorwärts schiebt. Die beim Vorwärtsgehen des Kolbens c verdrängte Flüssigkeit tritt durch die Kanäle 7, 6 und 8 in den Zylinder des Kolbens b ein und schiebt letzteren voran, bis der Stempel d sich auf den zu schließenden Niet aufsetzt. Während dieses Arbeitsganges der Kolben c und b ist der von den Kanälen 4 und 5 gebildete Auspuffkanal frei.Compressed air enters the channel 1 of the cock a 'and in the position shown in the channels 2 and 3 and from there behind the piston c, which it pushes forward. The liquid displaced as the piston c moves forward enters the cylinder of the piston b through the channels 7, 6 and 8 and pushes the latter forward until the punch d touches the rivet to be closed. During this operation of the pistons c and b , the exhaust duct formed by the ducts 4 and 5 is free.
Sobald der Stempel d sich fest auf den Niet aufgesetzt hat, wird der Hahn a um etwa 900 gedreht, so daß die Verbindung zwischen den Zylindern der Kolben b und c unterbrochen und die Flüssigkeit im Zylinder des Kolbens b eingeschlossen wird.As soon as the plunger d is placed firmly on the rivet, the cock a is rotated approximately 90 0, so that the connection between the cylinders of the piston b and c stopped and the liquid in the cylinder of piston B is included.
Nach Fertigstellung des Nietkopfes dreht man den Hahn a um etwa 90° weiter, so daß die Verbindung zwischen den beiden Zylindern wieder hergestellt und gleichzeitig durch die Kanäle 1, 2 und 4 Druckluft auf die Ringfläche des Kolbens b zur Wirkung kommt. Dabei ist gleichzeitig der durch die Kanäle 3 und 5 gebildete Auspuffkanal frei. Die Kolben c und b werden auf diese Weise in die gezeichnete Stellung zurückgebracht, wobei die Flüssigkeit durch die Kanäle 8, 6 und 7 in den Zylinder des Kolbens c zurückgedrückt wird.After completion of the rivet head, the cock a is turned by about 90 °, so that the connection between the two cylinders is restored and at the same time compressed air comes into effect through the channels 1, 2 and 4 on the annular surface of the piston b. At the same time, the exhaust duct formed by ducts 3 and 5 is free. The pistons c and b are returned to the position shown in this way, the liquid being pushed back through the channels 8, 6 and 7 into the cylinder of the piston c .
Dreht man hierauf den Hahn α um i8o° zurück, so beginnt die Arbeit der Kolben b und c in der beschriebenen Weise von neuem.If you then turn the valve α back by 180 °, the work of pistons b and c begins anew in the manner described.
