Abstract

A pipe-bending machine bends low-strength pipes and has esp. a bending arm (1) with plastic a cylindrical insert (2). The plastic cylindrical insert has a transverse guide groove in the bending axis. The insert size is determined in accordance with the pipe to be bent. The cylinder is supported in the vertical axis by a prism (3), semi-circle or link-plate (6) and a locking screw.

BeschreibungDescription Bieqekopf zum Biegen von Rohren mit geringer FestigkeitBending head for bending low strength pipes

Biegeköpfe in dieser Darstellung sind Vorrichtungsbestandteil für Kraftstoff-, Brems-, Lüftungs-, Kühl- und Versorgungsleitungen mit teilweise kurzen Abständen der Biegekoordinaten. Da vermehrt Leitungen aus Aluminium gefordert werden, ist das Biegen bei engen Biegekoordinaten wie herkömmlich (Stand der Technik) mit einer mitlaufenden Biegerolle problemgebunden. Durch den geringen Berührungsquerschnitt (linear) ist bei Rohrwerkstoffen mit geringen Festigkeiten Rohrdeformierungen und bei seriellen Arbeiten ohne Schmierstoff Abrieb zu erwarten.Bending heads in this illustration are part of the device for fuel, brake, ventilation, cooling and supply lines, sometimes with short distances between the bending coordinates. Since aluminum lines are increasingly being demanded, bending with narrow bending coordinates as is conventional (state of the art) with a rotating bending roller is problematic. Due to the small contact cross-section (linear), pipe deformation is to be expected with pipe materials with low strength and abrasion during serial work without lubricant.

Die Neuerung ist entgegen der Biegerolle durch einen verschleißfesten Kunststoffzylinder (2) ersetzt und in den Biegearm (1) eingelagert. Dieser Kunststoffzylinder (2) ist mit einer Gleitnut versehen, die in der Biegeachse eine Länge von 1,2 &khgr; Rohrdurchmesser aufweist. Die notwendige Parallelität der Gleitnut zum Rohrmantel (8) (Biegeachse) wird durch die einmalige Justierung und Arretierung der Stellschraube (5) zum Kunststoffzylinder (2) ermöglicht. Zur Mantelabstützung des Kunststoffzylinders (2) in der Vertikalachse ist ein Prisma (3) auf dem Biegearm montiert. Eine Verbindungsplatte (6) dient als Lagerung des Kunststoffzylinders (2) im oberen Zapfen in Verbindung mit Prisma (3).The innovation is that, in contrast to the bending roller, a wear-resistant plastic cylinder (2) is replaced and stored in the bending arm (1). This plastic cylinder (2) is provided with a sliding groove that has a length of 1.2 x pipe diameter in the bending axis. The necessary parallelism of the sliding groove to the pipe casing (8) (bending axis) is made possible by the one-time adjustment and locking of the adjusting screw (5) to the plastic cylinder (2). A prism (3) is mounted on the bending arm to support the casing of the plastic cylinder (2) in the vertical axis. A connecting plate (6) serves to mount the plastic cylinder (2) in the upper pin in connection with the prism (3).
