Problems solved by technology

However, such a processing method has resulted in the U-bend waveguide used in the feeder system or feed source system in the electromagnetic wave radar. Not only is the processing difficult and labor-intensive, but also prone to processing problems during the bending process. processing quality problem
Due to the unreasonable selection of the processing method of the U-bend waveguide, the U-bend waveguide used in the feeder system and the feed source system in the electromagnetic wave radar is prone to low yield, long processing cycle, Processing costs have risen sharply, etc.

Embodiment Construction

[0022] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0023] The following problems must be solved when processing the U-bend waveguide used in electromagnetic wave radar: It is necessary to meet the final processing accuracy and surface roughness of the U-bend waveguide used in electromagnetic wave radar, that is, the U-bend waveguide used in electromagnetic wave radar. The surface roughness of the cavity is 1.6um, and the surface roughness of the aluminum alloy sheet welded with it is also 1.6um. At the same time, it must be ensured that the processing method selected by the present invention can complete the processing with high quality and quantity. The technical method adopted in the present invention is: replace the special-made waveguide blank material with the U-shaped curved waveguide blank made of aluminum alloy plates with different thicknesses through milling and welding, so that the original fitter is us...

Abstract

The invention relates to a U-shaped bent waveguide processing method which comprises the following steps: at first, processing a tool of a U-shaped groove in a milled part, then, milling a U-shaped cavity, brazing a cover plate on the U-shaped cavity, placing the U-shaped cavity welded with the cover plate in the U-shaped groove of the tool, milling the cover plate with the size consistent with the boundary dimension of the U-shaped bent waveguide, and finally, welding flanges at two ends of the U-shaped cavity.

Description

technical field [0001] The invention relates to the field of U-bend waveguide processing, in particular to a U-bend waveguide processing method. Background technique [0002] Electromagnetic wave radar is currently widely used in many aspects such as early warning, search, guidance, artillery sighting, battlefield surveillance, and identification of friend or foe, and U-shaped curved waveguide is an indispensable key component of electromagnetic wave radar feeder system or feeder system The most important components in electronic equipment such as electromagnetic wave radar, the U-shaped bending wave of the feeder system or feed source system in electromagnetic wave radar requires high thermal conductivity and high electrical conductivity in addition to high processing accuracy and high demand. Due to the high processing precision requirements of the U-bend waveguide, the processing quantity is generally large, so it brings problems to the high-precision, high-quality and ba...
