Bending tool for rectangular waveguide - has two pressure elements placed on waveguide at suitable distance from each other

摘要

These pressure elements (2, 2') are placed on the wave-guide (1) wide side which will be after bending on its outside, and the spacing between them corresponds to the required radius of curvature; their contact surfaces are placed in the areas of the waveguide transversal ribs; two bending levers (3, 3') consist of two plates (5, 6; 5', 6') parallel to each other, at a distance equal to the wave guide wide sides; a lever (10, 10') on their side, and counter-pressure elements (9, 9') between the above pressure elements (2, 2'); a traction device (13) has a wound traction cable (17) attached by its face end to one of the levers (10'), while the device is mounted on the other (10).
