Description
Die vorliegende Erfindung hat eine Verbesserung an solchen Vorrichtungen zum Biegen dünnwandiger Rohre zum Gegenstand, bei welchen gegenüber einer halbkreisförmig gerillten Grundform die Biegerollen federnd nachstellbar auf einem Druckhebel angeordnet sind. Gegenüber den bekannten Vorrichtungen dieser Art wird bezweckt, das Festhalten und Einlegen der zu biegenden Rohre einfach ίο und sicher zu gestalten, was dadurch erreicht wird, daß eine mit einem Druckhebel versehene, unter Federwirkung gegen die Formplatte anstellbare Spannplatte angebracht ist, deren Schwinghebel ein mit den Führungsschlitten der Biegerollen zusammenwirkendes Quer j och trägt, so daß bei dem durch Abwärtsbewegen des Druckhebels erfolgenden Abrücken der Spannplatte auch die Biegerollen von der Formplatte weggedrängt werden.The present invention has an improvement in such bending devices thin-walled tubes to the subject, in which opposite a semicircular grooved Basic shape the bending rollers are resiliently adjustable on a pressure lever. Compared to the known devices the purpose of this type is to make it easy to hold and insert the pipes to be bent ίο and to design safely, which is achieved in that a provided with a pressure lever, under spring action against the mold plate adjustable clamping plate is attached, the rocker arm with the guide carriage the bending rollers cooperating cross yoke carries so that by moving downwards When the pressure lever moves away from the clamping plate, the bending rollers are also pushed away from the mold plate will.
Eine solche Vorrichtung zum Biegen dünnwandiger Metallrohre ist in den Abb. 1 bis 4 der Zeichnung in einer Ausführungsform dargestellt, wobei die Abb. 1 und 2 lotrechte s5 Schnitte nach Linie A-B bzw. C-D der Abb. 3, j diese selbst die Draufsicht auf die Vorrichtung in der Ruhestellung und Abb. 4 die ! Draufsicht in der Biegestellung erkennen lassen.Such a device for bending thin-walled metal pipes is shown in Figs. 1 to 4 of the drawing in one embodiment, Figs. 1 and 2 vertical s5 sections along line AB and CD of Fig. 3, j this itself the plan view of the Device in the rest position and Fig. 4 the ! Show the top view in the bending position.
Auf der Grundplatte 1, auf welcher die ; Formplatte 3 mittels der Stützen 2 und der j Schraubenbolzen 4 angeordnet ist, ist der j Lagerkopf 18 befestigt, um dessen Zapfen 19 ■ ein Schwinghebel 20 drehbar angelenkt ist, ' welcher von der Druckstange 21 erfaßt wird und an seiner Vorderseite ein Quer j och 22 ; trägt. Am freien Ende der Druckstange 21 greift eine an der Grundplatte 1 mittels der Schraube 23 befestigte Zugfeder 24 an, welche \ den Schwinghebel derart nach vorn zu ziehen ; sucht, daß die zum Einspannen des zu biegen- I den Rohres dienende, an der Vorderseite ebenfalls halbkreisförmig gerillte Spannplatte 25, welche auf dem Schwinghebel 20 sitzt, gegen die Formplatte 3 gepreßt wird. Das Querjoch 22 ist, wie aus Abb. 4 zu ersehen, soweit beiderseits verlängert, daß es mit seiner Rückfläche der Vorderseite der Schlitten 9 gegenübersteht, welche in Schlitzen 8 der Druckhebel 7 gleiten und die halbkreisförmig gerillten Biegerollen 13 tragen. Infolgedessen können, beim Niederdrücken des DruckhebelsOn the base plate 1 on which the; Form plate 3 is arranged by means of the supports 2 and the screw bolts 4, the bearing head 18 is fastened, around the pin 19 of which a rocker arm 20 is pivoted, which is grasped by the push rod 21 and a cross yoke 22 on its front side ; wearing. At the free end of the push rod 21, a tension spring 24 attached to the base plate 1 by means of the screw 23 engages, which pulls the rocker arm forward in this way; seeks that the clamping plate 25, which is used to clamp the pipe to be bent and which is also semicircularly grooved on the front and which sits on the rocker arm 20, is pressed against the mold plate 3. The cross yoke 22 is, as can be seen from Fig. 4, extended on both sides to such an extent that its rear surface faces the front side of the carriage 9, which slide in slots 8 of the pressure lever 7 and carry the semicircular grooved bending rollers 13. As a result, when the pressure lever is depressed
21 zum Zwecke des Einspannens eines zu biegenden Rohres gleichzeitig durch das Querjoch21 for the purpose of clamping a pipe to be bent at the same time through the cross yoke
22 auch die Biegerollen 13 unter Anspannen der gegen deren Führungsschlitten 9 wirkenden Federn 17 soweit zurückbewegt werden, daß das Rohr von oben eingelegt bzw. nach dem Biegen nach oben ausgeführt werden kann. Auf der Spannplatte 25 ist zweckmäßig eine Anschlagschiene 26 befestigt, welche mit ihrem vorderen abgebogenen Ende die Länge begrenzt, auf welche das zu biegende Rohr über die eine Seite der Formplatte hinausragen darf.22 also the bending rollers 13 while tensioning the ones acting against their guide carriage 9 Springs 17 are moved back so far that the tube is inserted from above or after bending upwards. On the clamping plate 25 is useful a stop rail 26 is attached which, with its front bent end, limits the length to which the to be bent Pipe may protrude beyond one side of the mold plate.
