Description

Rohrbiegewerkzeug Die Erfindung betrifft ein Rohrbiegewerkzeug mit einem Formstück, einem im Formstückzentrum angelenkten Biegehebel und einem an dessen Ende schwenkbar gelagerten, eine Biege- und eine Druckrolle tragenden Griffhebel. Biege- und Druckwelle biegen das Rohr um das Formstück. Zum Festklemmen des Rohres beim Biegevorgang, d. h. in der gegen das Formstück geschwenkten Arbeitsstellung des Griffhebels, liegt die Achse der Druckrolle etwa auf der das Formstückzentrum und den Griffhebelschwenkpunkt verbindenden Mittellinie des Biegehebels.Pipe bending tool The invention relates to a pipe bending tool a fitting, a bending lever articulated in the center of the fitting and one on its The end of the pivoted handle lever, which carries a bending roller and a pressure roller. Bending and pressure waves bend the pipe around the fitting. For clamping the pipe during the bending process, d. H. in the working position pivoted against the fitting of the handle lever, the axis of the pressure roller lies roughly on the center of the molding and the center line of the bending lever connecting the handle lever pivot point.

Um die Druckrolle beim Biegevorgang genau in der Arbeitsstellung zu halten, was mit den bekannten Vorrichtungen nicht möglich ist, ist nach der Erfindung die Achse der Druckrolle in einem die Schwenkbewegung des Griffhebels begrenzenden Schlitz des Biegehebels geführt.In order to keep the pressure roller exactly in the working position during the bending process keep what is not possible with the known devices, is according to the invention the axis of the pressure roller in a limiting the pivoting movement of the handle lever Slit of the bending lever out.

Diese Ausbildung hat den Vorteil, daß durch das Festklemmen des zu biegenden Rohres in begrenzter Stellung sich der Biegevorgang in dauernd gleichbleibender Weise vollzieht.This training has the advantage that by clamping the to bending tube in a limited position, the bending process is constantly constant Wisely.

In der Zeichnung ist das erfindungsgemäße Rohrbiegewerkzeug in einem Ausführungsbeispiel dargestellt. Es zeigt A b b. 1 das Rohrbiegewerkzeug in der Stellung, welche es nach dem formschlüssigen Einklemmen des Rohres vor dem Beginn des Biegens einnimmt, in Seitenansicht, A b b. 2 einen Schnitt nach der Linie A-B in Ab b. 1, A b b. 3 die Seitenansicht nach A b b. 1, nachdem das Rohr um fast 180° gebogen ist.In the drawing, the pipe bending tool according to the invention is in one Embodiment shown. It shows A b b. 1 the pipe bending tool in the Position, which it is after the form-fitting clamping of the pipe before the beginning of bending, in side view, A b b. 2 a section along the line A-B in Ab b. 1, A b b. 3 the side view according to A b b. 1 after the pipe turned almost 180 ° is bent.

Das Rohrbiegewerkzeug hat zwei um eine Achse 1, welche das Biegeformstück 2 trägt, schwenkbare Hebel 3 und 4. Der eine Hebel, der Anschlaghebel 3, trägt einen Rohranschlag 5. Mit dem anderen Hebel, dem Biegehebel 44, ist ein Griffhebel ? durch einen Bolzen 8 gelenkig verbunden. Der Griffhebel 7 trägt eine Biegerolle 6 und eine Druckrolle 9. Die Achse 10 der Druckrolle 9 gleitet in einem Schlitz 11 des Biegehebels 4, welcher der Achse 10 die zu ihrer Klemmstellung erforderliche Beweglichkeit gibt, gleichzeitig aber auch ihre Bewegung begrenzt. Durch den Griffhebel 7 des Biegehebels 4 wird die Achse 10 der Druckrolle 9 bis ungefähr in die Mittellinie gebracht, welche das Fonnstückzentrum 1 und den Griffhebelschwenkpunkt 8 miteinander verbindet. Formstück 2, Biegerolle 6 und Druckrolle 9 haben Profilrillen, die dem Durchmesser des zu biegenden Rohres 12 angepaßt sind.The pipe bending tool has two around an axis 1, which the bending fitting 2 carries pivotable levers 3 and 4. One lever, the stop lever 3, carries one Pipe stop 5. The other lever, the bending lever 44, is a handle lever? by a bolt 8 articulated. The handle lever 7 carries a bending roller 6 and a pressure roller 9. The axis 10 of the pressure roller 9 slides in a slot 11 of the Bending lever 4, which of the axis 10 the mobility required for its clamping position there, but at the same time also limits their movement. The handle lever 7 of the Bending lever 4 is the axis 10 of the pressure roller 9 to approximately in the center line brought, which the Fonnstückzentrum 1 and the handle lever pivot point 8 with each other connects. Form piece 2, bending roller 6 and pressure roller 9 have profile grooves that correspond to the Diameter of the tube 12 to be bent are adapted.

Bei dem den Rohranschlag 5 tragenden Anschlaghebel 3 ist der Handgriff 13 verstellbar, um diesen in eine für die Handhabung günstige Stellung zum Griffhebel 7 bringen zu können. Der Handgriff 13 führt sich mit einem Schlitz 14 auf dem Bolzen 15 des Anschlaghebels 3 und greift mit einem Bolzen 16 in eine der Rasten 17 des Hebels 3 ein. Die Anordnung der Rasten 17 und des Bolzens 16 kann auch umgekehrt werden.In the case of the stop lever 3 carrying the pipe stop 5, the handle is 13 adjustable in order to move it into a favorable position for handling with respect to the handle lever 7 to be able to bring. The handle 13 is guided with a slot 14 on the bolt 15 of the stop lever 3 and engages with a bolt 16 in one of the notches 17 of the Lever 3. The arrangement of the notches 17 and the bolt 16 can also be reversed will.
