Description

- s,. rr @^F4 Einrichtung zum fierst" ' Arischer Rohrheizkörper .eee Das Patent 636 889 bezieht sich auf eine Einrichtung zum Herstellen elektrischer Rohrheizkörper durch Einbringen körniger Isoliermasse in Metallröhre, bei der der im Mantelrohr ausgespannte Heizleiter mittels eines schwingenden Stopfstempels mit der Isoliermasse umstopft wird. Das Mantelrohr ist nachgiebig gelagert angeordnet und wird dem Stopfstempel mit beliebig .einstellbarem konstantem Druck entgegengehalten. Dadurch wird eine überall gleichmäßig dichte Lagerung der isolierenden Masse im Mantelrohr erzielt. - s ,. rr @ ^ F4 Device for the first "'Aryan tubular heating element .eee The patent 636 889 relates to a device for producing electrical tubular heating elements by introducing granular insulating material into metal tubes, in which the heating conductor stretched out in the jacket tube is stuffed with the insulating material by means of a vibrating tamping punch. The casing tube is arranged in a flexible manner and is held against the stuffing ram with any constant pressure that can be adjusted. As a result, the insulating material in the jacket pipe is supported evenly and tightly everywhere.

Die von den schnellen Schwingungen des Stopfstempels ausgehenden Impulse können am Mantelrohr und seinem Träger Schwingungen verursachen, die den Stopfvorgang stören.The impulses emanating from the rapid vibrations of the tamping ram can cause vibrations on the jacket pipe and its support, which the stuffing process disturb.

Oft werden die inneren Reibungen viner solchen Einrichtung ausreichen, um die vom Stopfstempel hervorgerufenen Impulse durch Umwandlung in Wärme zu vernichten, so daß das Mantelrohr nicht in schwingende Bewegung gerät. Da man aber anderseits bestrebt ist, die inneren Reibungen der Maschine auf ein möglichst geringes Maß zu bringen, ist es erforderlich, besondere Anordnungen zur Vernichtung der Energie zu treffen.Often the internal frictions of such a device will suffice, to destroy the impulses caused by the stuffing ram by converting them into heat, so that the jacket pipe does not start to oscillate. But on the other hand strives to reduce the internal friction of the machine to the lowest possible level To bring it is required special arrangements to destroy the energy hold true.

Erfindungsgemäß ist nun eine die dem Mantelrohr bzw. den mit ihm starr verbundenen Teilen durch den Stopfstempel aufgedrückten Schwingungen dämpfende Bremse vorgesehen.According to the invention, one of the jacket pipe or the one with it is now rigid connected parts by the tamping stamp pressed on vibration damping brake intended.

In den Figuren ist ein Ausführungsbeispiel der Erfindung dargestellt. Fig. i zeigt die Gesamtanordnung der Stopfeinrichtung, die Fig. 2 und 3 die Bremse am Kolben für sich. In dem Mantelrohr 15 (Fig. i ) ist der Heizleiter ausgespannt, der von dem durch die Kurbelschleife a6 in schwingende Bewegung versetzten Stopfstempel 16 mit körniger Isoliermasse umstopft wird. Das Mantelrohr wird von dem Kolben4i getragen und dem Stopfstempel mit einem beliebig einstellbaren konstanten Druck entgegengehalten, indem der Druckzylinder 37 beispielsweise unter pneumatischem Druck steht, der durch die Leitung 4o zugeführt wird.An exemplary embodiment of the invention is shown in the figures. Fig. I shows the overall arrangement of the tamping device, Figs. 2 and 3 the brake on the piston for itself. The heating conductor is stretched out in the jacket tube 15 (Fig. I), the tamping ram set in oscillating motion by the crank loop a6 16 is repacked with granular insulating compound. The jacket tube is held by the piston 4i worn and the stuffing ram with an arbitrarily adjustable constant pressure held against by the pressure cylinder 37, for example, under pneumatic Pressure is present, which is supplied through line 4o.

Um die dem Kolben 41 aufgedrückten Schwingungen zu dämpfen, sind Reibbacken 44 angeordnet, die durch Federn 45 oder auch durch entsprechende Anordnung von Gewichten an den Kolben angepreßt werden. Die Backen 44 und die Federn 45 werden mittels eines Ringes 47 und Schrauben 48 von dem Flansch 49 des Druckzylinders 37 gehalten. Der Druck der Federn ,15 ist mittels der Schraube1146 einstellbar. Man wird ihn so wählen, daß die entstehende Dämpfung gerade genügt, um störende Schwingungen zu vernichten.In order to dampen the vibrations pressed on the piston 41, friction shoes are used 44 arranged by springs 45 or by a corresponding arrangement of weights be pressed against the piston. The jaws 44 and the springs 45 are by means of a Ring 47 and screws 48 held by the flange 49 of the pressure cylinder 37. Of the The pressure of the springs 15 can be adjusted using the screw 1146. He will be chosen like this that the resulting damping is just enough to destroy disturbing vibrations.
