Abstract

ABSTRACT OF THE DISCLOSURE

The present invention provides a device for bending thin metallic pipes suitably used as a fuel supply pipe, brake pipe and the like of an automobile, which are bent at a plurality of portions thereof not in the same direction but in three-dimensional directions.
The device according to the invention includes a station-ary mold form having a first and a second bending section to the shapes of which a metallic pipe is bent and a guide member erected upright on the mold form at the second bending section, a bending member arranged outside the mold form and movable toward the latter for bending the metallic pipe, a rotor for rotating the bending member and an actuator for operating the rotor through a wire.
The advantages of the invention are that unlike the con-ventional device, the bending member located outside the mold form is attached to the rotor which is rotated by the actu-ator through the wire, the interference of the actuator with the metallic pipe or other parts of the device or with another actuator is prevented and the structure of the device is sim-plified.
