Processing method of composite slow-wave tube shell

Abstract

The invention relates to a processing method of a composite slow-wave tube shell. The composite slow-wave tube shell comprises docking pole shoes, pole shoes, spaced rings, transfer pole shoes, an adapter and a positioning core rod. The processing method comprises the following steps: mounting and welding the docking pole shoes, the pole shoes, the spaced rings, the transfer pole shoes and the adapter, and then forming an inner hole processing channel of the tube shell; linearly cutting and processing the inner hole processing channel to the honing size of an inner hole channel, and forming an inner hole honing channel; honing the inner hole honing channel to reach a design size of the inner hole channel; testing; carrying out oil removal cleaning; performing an air-tightness test. According to the method, an advanced slow-wire cutting processing technology and an inner circle honing process are used for processing the inner hole channel of the composite slow-wave tube shell for a helix traveling-wave tube. The method disclosed by the invention has the advantages of high inner-diameter precision of the processed tube shell, good inner surface smoothness, high concentricity, low air leak rate of the processed composite tube shell, and the like.

Description

technical field [0001] The invention relates to the manufacture of the slow wave of the traveling wave tube, more specifically, the invention relates to a processing method for the composite slow wave shell of the Ku band traveling wave tube. Background technique [0002] As a vacuum microwave power amplifier, traveling wave tubes have the advantages of wide frequency band, large gain, high efficiency, and large output power. They are widely used in various military microwave transmitters and are known as the "heart" of weapons and equipment. [0003] The slow wave system is an important part of the traveling wave tube. With the continuous increase of the power of the traveling wave tube, the problem of heat dissipation has become a difficult problem that must be solved. At present, a slow wave structure of composite shell is designed in the high power traveling wave tube , this structure effectively solves the slow wave heat dissipation. In the past, the helical slow-wave ...

AI Technical Summary

Problems solved by technology

In the past, the helical slow-wave shell was processed by spinning, and the composite shell had been welded with iron pole shoes, intermediate rings, and output adapters in advance due to its special structure. Complicated, the spinning processing method is no longer suitable for the processing of the composite shell, and other processing methods must be found to complete the processing of the slow wave structure of the composite shell
