Description

Biegevorrichtung zum Runden von Rohren aus Blechen Die Erfindung betrifft eire Biegevorrichtung zum Runden von Rohren aus Blechen. Sie besteht in der Anordnung von -vier Walzen, einer oberen, zwei mittleren und einer unteren, zur gleichzeitigen Rundung von zwei Schüssen, die oberhalb und unterhalb der mittleren Walzen durchlaufen.Bending device for rounding tubes from sheet metal. The invention relates to A bending device for rounding tubes made of sheet metal. It consists in the arrangement of four reels, one upper, two middle and one lower, for simultaneous Rounding of two shots that go through above and below the middle rollers.

Auf der Zeichnung ist eine Ausführungsform einer Vorrichtung gemäß der Erfindung in einer Abbildung dargestellt: Das Biegen von Rohrschüssen, insbesondere von solchen kurzer Länge, erfolgt zwischen Biegewalzen i, a, 3, 4, die fliegend angeordnet sind. Die Walzen i und 2 sind angetrieben und in -einem Walzenständer 5 gelagert. Der Antrieb erfolgt von einem Motor aus über einen Räderkasten. Die Walzen 3 und 4 sind durch einen Anstellmotor und Schraubenspindeln;, S, 9, io und ii heb- und senkbar. Sie können gleichfalls angetrieben werden; im vorliegenden Falle laufen sie jedoch lose. Die zu biegenden Bleche, die an den Enden vorgebögen sein können, sind auf Tischen 12, 13 gelagert.The drawing shows an embodiment of a device according to the invention in a figure: The bending of pipe sections, in particular those of short length, takes place between bending rollers i, a, 3, 4, which are arranged overhung. The rollers i and 2 are driven and stored in a roller stand 5. It is driven by a motor via a gear box. The rollers 3 and 4 can be raised and lowered by an adjusting motor and screw spindles ;, S, 9, io and ii. They can also be driven; in the present case, however, they run loose. The sheets to be bent, which can be pre-bent at the ends, are stored on tables 12, 13.

Das Biegen erfol&t so, daß die Walzen 3 und q. angepreßt werden, wobei- gleichzeitig die Drehrichtung der Walzen i und 2 geändert wird. Der Tisch 13 kann dabei seine Lage beibehalten, während der Tisch i 2 sich senkt, um die Durchbiegung des Bleches 15 zu ermöglichen. Die vollständige Rundung erfolgt durch mehrmaliges Hinundherwalzen der Bleche 14 und 15. Die fertiggebogenen Rohrschüsse können seitwärts aus den Walzen 3 und 4 abgezogen werden.The bending is done so that the rollers 3 and q. be pressed, whereby the direction of rotation of the rollers i and 2 is changed at the same time. The table 13 can maintain its position while the table i 2 lowers in order to allow the sheet 15 to bend. The complete rounding takes place by rolling the sheets 14 and 15 back and forth several times. The finished bent pipe sections can be pulled sideways from the rollers 3 and 4.
