Embodiment Construction

[0032] The technical solution of the present invention will be further described in detail below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following description.

[0033] Such as figure 2 As shown, an integrated wide and narrow ridge waveguide includes an upper cavity 1, a lower cavity 2 and a plurality of middle cavities 3. A waveguide cavity is formed between the upper cavity 1 and the lower cavity 2. The structure of the waveguide cavity can refer to Figure 6 shown. The middle cavity body 3 is evenly distributed among the waveguide cavities, and divides the waveguide cavity into alternating wide-side ridge waveguides 6 and narrow-wave ridge waveguides 7. Its structure is as follows image 3 , from left to right are broad ridge waveguide 6-narrow ridge waveguide 7-broad ridge waveguide 6, narrow ridge waveguide 7.... Among them, the middle cavity body 3 is mainly divided into three types, and its specif...

Abstract

The invention relates to an integrated wide-narrow ridge waveguide and a manufacturing process thereof. The waveguide comprises an upper cavity, a lower cavity and a plurality of middle cavities, wherein waveguide cavities are formed between the upper cavity and the lower cavity, the middle cavities are uniformly distributed between the waveguide cavities, each waveguide cavity is divided into wide-side ridge waveguides and narrow-wave ridge waveguides which are sequentially alternated, the upper cavity, the lower cavity and the middle cavities are positioned through seam allowance structures,and brazing filler metal is embedded into grooves of the seam allowance structures in advance. According to the scheme, the waveguide is divided into the upper cavity, the lower cavity and the plurality of middle cavities; then, positioning among the upper cavity, the lower cavity and the plurality of middle cavities is completed by utilizing the seam allowance structures, and the brazing fillermetal is embedded into the seam allowance grooves in advance; after the positioning is completed, welding of a product is completed through vacuum brazing; and compared with a traditional extrusion technology, by using the process of the invention, precision of a product manufactured through the scheme is higher, deformation caused by extrusion cannot be generated, and the product precision is greatly improved.

Description

technical field [0001] The invention relates to the technical field, in particular to an integrated wide and narrow ridge waveguide and a preparation process thereof. Background technique [0002] The weather radar antenna array is composed of a plurality of equal number of wide and narrow crack line sources. The source of wide and narrow crack line adopts such as figure 1 The shown wide and narrow ridge waveguides, where A is the wide ridge waveguide and B is the narrow ridge waveguide. The existing crack line source is processed by standard waveguide aluminum profiles, and the waveguide uses aluminum rods to obtain aluminum profiles with different cross-sectional shapes through hot melting and extrusion. Due to the high precision, the products manufactured by the traditional profile extrusion process often cannot meet the precision requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to...
