Problems solved by technology

However, the rigidity of the steel plate becomes worse after being deformed by force, because when the steel plate is bent and stretched under force, the molecules are squeezed to generate heat, and the heat generated makes the rigidity of the original steel plate worse; Steel plate, after stamping deformation, its rigidity is also greatly reduced, and its deformation becomes large due to the influence of temperature and external force

Embodiment 1

[0025] The steel plate is formed into a parabolic steel plate in a mold. Then the mold equipped with the parabolic steel plate was heat-treated in brine with a mass concentration of 20% and a temperature of 20° C. for 3 minutes. Finally, the mold after heat treatment is opened in 2.4×10 5 Clamp the mold and press the parabolic steel plate under the pressure of 7s. The performance of the parabolic antenna finally obtained is shown in Table 1.

Embodiment 2

Abstract

The invention discloses a heat treatment method for a Ka-band parabolic antenna, comprising: forming a steel plate into a parabolic steel plate in a mold; placing the mold equipped with the parabolic steel plate in salt water for heat treatment; opening the mold after the heat treatment After the mold is closed, the parabolic steel plate is pressed together. The rigidity of the parabolic antenna obtained by the method of the present invention is better. When the bad weather changes, the thermal expansion and contraction coefficient of the antenna steel material becomes extremely small, which ensures the directivity of the antenna design, high focused radiation, and low disturbed characteristics.

Description

technical field [0001] The invention belongs to the technical field of parabolic antenna manufacturing, and in particular relates to a heat treatment method for a Ka-band parabolic antenna. Background technique [0002] The antenna system is the front-end equipment of radar, satellite communication, radio astronomy and other multi-purpose electronic equipment. High-precision antenna is the key equipment of the antenna system, especially for high-frequency antennas such as Ka-band. The accuracy of the antenna reflector is related to the operating frequency, and it is generally required that the maximum value of the Ka-band antenna reflector accuracy δ should be less than λ / 32. (Taking 30GHz as an example, 10 / 32=0.3125mm) is far higher than the Ku-band and C-band requirements. It is necessary to consider these factors in the selection of antenna reflector material. The reflective surface must be made of corrosion-resistant materials. Materials such as iron, stainless steel,...
