Abstract

Das Ausweitungs- und Bördelgerät besteht aus einem Schraubverschluß (9) zur Halterung des zu bearbeitenden Rohres (7). Die eigentliche Haltevorrichtung besteht aus zwei Backenhälften (17) mit einem Außenumfang von jeweils mehr als 180°. Die Innendurchmesser dieser Hälften (17) sind jeweils dem Außendurchmesser des zu bearbeitenden Rohres (7) angepaßt und mittels eines Bajonettverschlusses in zwei von einander weg und zu einander hin bewegbaren Körpern (4, 5) befestigt. The expansion and flaring device consists of one Screw cap (9) for holding the item to be processed Tube (7). The actual holding device consists of two jaw halves (17) with an outer circumference of each more than 180 °. The inside diameter of these halves (17) are each the outer diameter of the processing tube (7) adapted and by means of a Bayonet lock in two away from each other and closed bodies (4, 5) movable towards each other.

Für den Ausweitvorgang genügt ein einfaches dornartiges Werkzeug (13), das für die Bördelung mit einer oder mehreren Walzen (16) ausgestattet ist. A simple one is sufficient for the expansion process mandrel-like tool (13) which is used for flanging with a or several rollers (16).

Wenn die Haltevorrichtung nicht geschlossen ist, sperrt ein Bügel (18) das Einführen des Werkzeuges (13). If the holding device is not closed, locks a bracket (18) the insertion of the tool (13).

Als Antrieb für das Werkzeug (13) dient eine handelsübliche Handbohrmaschine, die längs einer Füh­ rung (14) bewegbar ist. A serves as a drive for the tool (13) commercially available hand drill, which runs along a Füh tion (14) is movable.
