Claims (5)

1. Aushalsvorrichtung zum Biegen der Ränder eines Loches in einem Rohr für einen das Loch umgebenden Kragen oder Hals, wobei die besagte Vorrich­ tung einen Körper (1), welcher in das Innere des auszuhalsenden Rohres ein­ führbar ist, und ein Formwerkzeug (3) aufweist, welches für die im Wesentli­ chen radiale Verschiebung relativ zum Rohr ausgelegt ist und einen Außen­ durchmesser hat, der im Wesentlichen gleich dem gewünschten Innendurch­ messer des Kragens ist, wobei eine Öffnung oder Vertiefung (9) in dem Körper (1) vorhanden ist, welche so dimensioniert ist, dass sie das Formwerkzeug (3) aufnimmt, wobei das besagte Formwerkzeug (3) unter der Führung der besagten Öffnung oder Vertiefung (9) betätigt werden kann, sowie Elemente (2, 4, 5, 14) aufweist, die mit einer Antriebsvorrichtung gekoppelt werden können, um das Formwerkzeug (3) aus dem Innern des Rohres nach außen zu bewegen, dadurch gekennzeichnet, dass die Öffnung oder Vertiefung (9) in ihrer Mittellinie mit einem Kalibrierdorn (11) ausgerichtet ist, der mit ihr richtungsgleich verschiebbar ist und der mittels einer äußeren Antriebsvorrichtung von außerhalb des Rohres nach innen in einen von dem Formwerkzeug (3) erzeugten Kragen gedrückt werden kann, wobei der Kalibrierdorn (11) den Kragen auf seine eigene Größe aufweitet, und nach seinem Eindringen in den Kragen der Kalibrierdorn (11) das Formwerk­ zeug (3) zurück in seine Ausgangsposition für einen neuen Aufhalsvorgang drückt.1. necking device for bending the edges of a hole in a tube for a collar or neck surrounding the hole, said device providing a body ( 1 ) which can be guided into the interior of the tube to be necked, and a molding tool ( 3 ) , which is designed for the essentially radial displacement relative to the tube and has an outer diameter which is substantially equal to the desired inner diameter of the collar, an opening or recess ( 9 ) being present in the body ( 1 ) which is dimensioned in such a way that it receives the molding tool ( 3 ), said molding tool ( 3 ) being able to be actuated under the guidance of said opening or recess ( 9 ), and has elements ( 2 , 4 , 5 , 14 ) which are associated with a drive device can be coupled to move the molding tool ( 3 ) from the inside of the tube to the outside, characterized in that the opening or recess ( 9 ) in its Center line is aligned with a calibration mandrel ( 11 ) which is displaceable with it in the same direction and which can be pressed inwards by means of an external drive device from the outside of the tube into a collar produced by the molding tool ( 3 ), the calibration mandrel ( 11 ) being the collar expands to its own size, and after it has penetrated into the collar of the calibration mandrel ( 11 ), the molding tool ( 3 ) presses back into its starting position for a new opening process. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass das in das Rohr eintretende Ende (12) des Kalibrierdorns (11) bogenförmig ausgebil­ det ist, um die Flanken (13) des Dornendes wesentlich dichter an der Mittellinie eines Rohres als die Endposition des oberen Endes des Formwerkzeugs (3) zu schieben.2. Device according to claim 1, characterized in that the end ( 12 ) of the calibrating mandrel ( 11 ) entering the tube is curved in order to form the flanks ( 13 ) of the mandrel end substantially closer to the center line of a tube than the end position of the upper end End of the mold ( 3 ). 3. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass der Kalibrierdorn (11) einen Durchmesser aufweist, der in Querrichtung (D2) größer ist als in Längsrichtung (D1) des Rohres.3. Device according to claim 1 or 2, characterized in that the calibration mandrel ( 11 ) has a diameter which is larger in the transverse direction (D 2 ) than in the longitudinal direction (D 1 ) of the tube. 4. Vorrichtung nach einem der Ansprüche 1 bis 3, dadurch gekennzeich­ net, dass der Kalibrierdorn (11) eine Außenfläche aufweist, die leicht konisch ist. 4. Device according to one of claims 1 to 3, characterized in that the calibration mandrel ( 11 ) has an outer surface which is slightly conical. 5. Vorrichtung nach einem der Ansprüche 1 bis 4, dadurch gekennzeich­ net, dass das Formwerkzeug (3) so dimensioniert ist, dass es einen Kragen­ durchmesser (D1) erzeugt, der größer als eine gewünschte Endgröße in der Längsrichtung ist, und einen Kragendurchmesser (D2), der in der Querrichtung eines Rohres kleiner als eine gewünschte Endgröße ist, wobei der Kalibrierdorn (11) eine Abweichung der Querabmessung(en) aufweist, welche die endgültigen Größen nach Wunsch korrigiert.5. Device according to one of claims 1 to 4, characterized in that the molding tool ( 3 ) is dimensioned such that it produces a collar diameter (D 1 ) which is larger than a desired final size in the longitudinal direction, and a collar diameter (D 2 ), which is smaller than a desired final size in the transverse direction of a pipe, the calibration mandrel ( 11 ) having a deviation in the transverse dimension (s) which corrects the final sizes as desired.
