Description

Für die Herstellung von Rohrmöbeln muß Bambusrohr gehogen:werden. Zu ,diesem. Zweck wird es zuerst vorgewärmt. Bis jetzt geschah das entweder in heißem Wasser oder mit einer elektrischen Heizung, wobei ein Heizelement an .der Stelle um den .Stab gewickelt wurde;, an der nachher der Bogen entstehen sollte: Es ist auch bekannt, Sperrholz um eine ibehei@zte Färm zu biegen.For the production of cane furniture, bamboo cane has to be cut. To, this. Purpose it is preheated first. So far this has happened in either hot Water or with an electric heater, with a heating element in place was wrapped around the .stab; on which the bow was to arise afterwards: It is also known to bend plywood to a heated size.

Das erfindungsgemäße Verfahren bestecht nun darin, daß das ,ganze Rohr in einem, Elektroofen gewärmt und dann mit Hilfe mindestens einerRollzwinge an eine Lehre angepreßt wird.: Nachdem so ein erster Bogen geformt ist, kann mit: einer Anpreßzwi.ngedieser Bogen festgehalten werden:, worauf die Rollzwinge in ein neues Drehzentrum eingesetzt und mit ihr ein zweiter Bogen geformt wird.The inventive method is now impressive that the whole Tube heated in an electric furnace and then with the help of at least one roller clamp is pressed against a jig .: After a first arch has been formed, you can do the following with: a pressure clamp of this arch are held: whereupon the roller clamp in a new turning center is used and a second arch is formed with it.

Erfindungsgegensäand isst ferner eine Vorrichtung zum Biegen von: Bambusrohr; gekennzeichnet durch eine Einspannvorrichtung für .das -zu biegende Rohr, mindestens eine verstellbare Bögenlehre sowie mindestens eine Rollzwinge und mindestens zwei Augen, in welche die Drehachse ;der Rollzwinge eingestellt werden kann.The subject of the invention also includes a device for bending: Bamboo cane; characterized by a clamping device for .the -to be bent Tube, at least one adjustable arch gauge and at least one roller clamp and at least two eyes in which the axis of rotation of the roller clamp is set can.

Im folgenden wird an Hand von Zeichnungen eine Ausführungsform beispielisweise beschrieben. Fig. i zeigt eine Draufsicht auf die. Vorrichtung; Fig. 2 ist eine .Seitenansicht :der Rollzwinge;, teilwei,se im Schnitt; Fig. 3 ist eine Seitenansicht der Anpreßzwinge, teilweise im, Schnitt.In the following, an embodiment is exemplified with reference to drawings described. Fig. I shows a plan view of the. Contraption; Fig. 2 is a . Side view: the roller clamp;, partly, se in section; Fig. 3 is a side view the pressure clamp, partly in, section.

Mit i wird ein Bambusrohr bezeichnet. Mit j Hilfe des Hebels 2 und. der Rätsche 3 wird es eingeklemmt, so d@aß es an. der verstellbaren Leitschiene 4 anliegt. Die Bogenlehre besteht aus den beiden, Bogenstücken 5 und 6, die mixt Muttern' 7 und 8 auf .der Unterlage 9 verstellbar befestigt sind. Das Zwischenstück io sichert den: stetigen Ühergang,der beiden Bogenstücke, 5 und, 6. In zwei Augen; ii und i2:paßt ein Drehzapifent 13 der @bl@lzwinge 14. In einem weiteren Auge 15 steckt der Drehzapfen 16 der Anp-reßzwinge i7. Diese Anpreiiizwinge könnte allerdings auch nichtdrehbar befestigt sein.I denotes a bamboo cane. With the help of lever 2 and. the ratchet 3 pinched it, so d @ ate it. the adjustable guardrail 4 is applied. The arch gauge consists of the two, arched pieces 5 and 6, the mixes nuts' 7 and 8 on the pad 9 are adjustable. The intermediate piece io ensures the: steady transition of the two arched pieces, 5 and, 6. In two eyes; ii and i2: fits a pivot pin 1 3 of the @ bl @ l clamp 14. The pivot pin 16 of the clamping clamp i7 is inserted in a further eye 15. This Anpreiiizwinge could, however, also be attached non-rotatably.
