Abstract
The utility model relates to an assembled wave guide bend, which comprises an assembled corner, a bending element and a round inclined horn; the utility model is divided into a casing and an inner cavity. The utility model is characterized in that the whole wave guide is composed of a plurality of independent subsections; an assembling interface between each of the subsections is arranged on a cornering position of the wave guide; each of the assembling interfaces is composed of a flange plate. The wave guide bend with a new structure has the same effect of microwave conducting performance of a wave guide bend which is formed by electrotyping in the prior art. Because the structure characteristic of the utility model is suitable for subsection machining, each of the subsections can be completed by means of conventional metalworking, and then, the subsections can be conveniently assembled and installed; therefore, the utility model has the advantages of easy manufacturing process and low cost.
Description
The utility model relates to a kind of microwave component, particularly a kind of waveguide bend simple in structure.
In microwave transmission system, in order to change electromagnetic transmission direction, need use turning and bender element, the general designation waveguide bend comprises two kinds of rectangular waveguides (E face turning and H face turning), two kinds of waveguide bends (the crooked and H face bending of E face).Waveguide corner structure commonly used has two kinds: a kind of for singly cutting the turning; Another kind is the double replacement type turning.The common feature of these elements is complex structures, and inner chamber has repeatedly Geometrical Bending, and its inner surface requires higher again, can't make with the general machining means, can only machine with electroforming process, manufacturing expense is very high, and this has had a strong impact on applying of conical scanning system radar.
The utility model provides a kind of assembly type waveguide bend in order to overcome this obstacle of the prior art, comprises modular turning, bender element and the askew loudspeaker of circle.The waveguide bend of new construction should have equal effect with the waveguide bend of prior art electrotyping forming on the microwave conductive performance, but should simplify significantly on process for machining and manufacturing, and manufacturing cost also should correspondingly descend.
The scheme of finishing the foregoing invention task is as follows: waveguide bend is divided into shell and inner chamber, it is characterized in that, whole wave guide is made of some independently segmentations, and the assembling interface between segmentation and the segmentation is located at the turning of waveguide, and the assembling interface is made of ring flange.
The assembly type waveguide bend that the utility model provides, comprise modular turning, bender element and the askew loudspeaker of circle, the waveguide bend of new construction has equal effect with the waveguide bend of prior art electrotyping forming on the microwave conductive performance, because of its design feature is suitable for segmental machining, each section can be finished with conventional metal working means, aggregate erection easily then, so on manufacturing process, simplify significantly, manufacturing cost also obviously descends, overcome waveguide bend processing difficulties in the prior art, problems such as manufacturing cost is too high have been eliminated an obstacle when promoting the use of conical scanning formula radar.
Now be described further with embodiment in conjunction with the accompanying drawings.
Fig. 1, Fig. 2, Fig. 3 are respectively the structural representation of embodiment 1,2,3.
Embodiment 1, the waveguide turning, and with reference to Fig. 1: the turning is made of three sections straight wave guides assemblings, and the two ends of each section straight wave guide are equipped with flange.Be assembled in the internal diameter difference of two sections waveguides 4,5 at two ends, it is conical that the inner core of middle one section straight wave guide 2 is, and the bore at the two ends internal diameter with the two ends waveguide respectively is identical.The bore that is flange 1 one ends is identical with the internal diameter of waveguide 4; The bore of flange 3 one ends is identical with the internal diameter of waveguide 5, and the angle of straight wave guide 2 two ends ring flanges and its axis is calculated by Theory of Electromagnetic Field, its assembling is shaped after, whole angle is identical with traditional electroforming corner structure.
Embodiment 2, and with reference to Fig. 2: basic structure is identical with last example, but angle, the direction difference of middle one section waveguide two ends ring flange.
