Description

Technical Field

[0001] The utility model relates to the technical field of waveguide tube processing, in particular to a tool for bending a large arc-shaped waveguide tube. Background Art

[0002] Waveguides are used to transmit ultra-high frequency electromagnetic waves, through which pulse signals can be transmitted to the destination with minimal loss. They are hollow metal conduits or metal-coated tubes with very smooth inner walls.

[0003] In the actual production process, the waveguide tube needs to be bent to meet the actual installation requirements. During the actual use of the existing bending tool for the waveguide tube, the surface of the waveguide tube will be stretched when the waveguide tube is bent. The edge of the existing bending tool is in direct contact with the waveguide tube, which will cause relative displacement during the actual bending process, thereby damaging the outer wall of the waveguide tube and affecting the processing effect. In view of this, we propose a circular arc-shaped large waveguide tube bending tool. Utility Model Content

The position of the moving part 300 is adjusted to drive the two columns 420 to slide on the outer wall of the waveguide tube, thereby realizing the bending of the waveguide tube.

An arc block 120 is fixedly installed on the outer wall of the upper end of the cylinder 110, and the curvature of the arc block 120 is adapted to the curvature of the arc groove 101. By the arc groove 101 provided, the sliding matching relationship between it and the column 420 is matched, when the moving member 300 adjusts its position, it will drive the column 420 provided to adjust its position, thereby enabling the waveguide to bend. Further, by the arc block 120 fixedly provided on the cylinder 110, in the actual bending process, it can limit the waveguide bending center, avoid the situation such as depression at the bending center of the waveguide, and ensure the bending effect of the waveguide.

During the actual bending process, the column 420 will slide on the outer wall of the waveguide, thereby avoiding contact at a fixed position, effectively avoiding the formation of scratches on the outer wall of the waveguide, and ensuring the bending effect.

At the same time, as the bending continues, the amount of gas entering the cavity will also increase, thereby increasing the contact force with the waveguide tube to cater to the increasing contact force between the waveguide tube and the column 420.
