Method for processing resonance pole structure

Abstract

The invention provides a resonant column structure processing method, which comprises the following steps: processing a pipe body with a lower hopper-like connector from aluminum, steel, copper or brass bars; processing a flange from aluminum, steel, copper or brass bars; and connecting the flange with the pipe body through pins to obtain the resonant column. The method has the advantages of high material utilization rate, less processing time, low processing cost, no need for auxiliary equipment (such as mold), simple procedure, and easy implementation of standard design.

Description

technical field [0001] The invention relates to a manufacturing method of an electrical product, in particular to a processing method of a resonant column structure. Background technique [0002] The resonant column is one of the elements constituting the cavity filter. According to the generation principle of the resonant frequency of the cavity filter, the resonant column and the closed metal cavity jointly generate the resonant frequency, thereby realizing the frequency required by the filter. Resonant columns are also called resonant rods. The resonant column needs to have good conductivity, so the material is mostly made of precious aluminum, steel, copper or brass with silver plating on the surface. [0003] The structure of the resonant column is as figure 1 , figure 2 As shown, it includes a pipe body 1 with a flange 2 on the upper part of the pipe body and a funnel-shaped connector 3 for inserting a countersunk screw to fix the resonant column and the resonant ...

AI Technical Summary

Problems solved by technology

Since the coaxiality, flatness, roughness and linear dimensions of the resonant column itself have a great influence on the performance of the filter, the processing equipment mostly uses CNC lathes and requires high skills for the manufacturer, and the production cycle is long

At the same time, the unique structure of the resonant column itself also determines the waste of materials, and the material utilization rate is only 50% to 60%.
