Abstract

The invention discloses a method and a device for airtight wire sealing anaerobic sintering. A sintering furnace is vertically fixed on a bracket, an outer guide wheel is arranged above the sintering furnace, an alcohol tank is arranged below the sintering furnace, and an inner guide is arranged inside the alcohol tank. The lower end of the alcohol tank is set on the support frame, and the two sides of the support are respectively equipped with a wire-releasing device and a wire-receiving device. There is a guide wheel between the wire-receiving device and the sintering furnace, and a temperature control device is installed on one side of the sintering furnace. The wire enters the sintering furnace through the alcohol tank, and the alcohol wetted on the surface of the wire reacts in the sintering furnace to discharge oxygen, and then the aviation wire is sintered through the device, so that the aviation wire is wrapped and insulated during the sintering and sealing process, and the conductor is avoided The purpose of oxidation occurs with high temperature in an aerobic environment.

Description

Technical field: [0001] The invention relates to the technical field of electric wire and cable processing, in particular to an oxygen-free sintering method and a device thereof for aviation wire sealing. Background technique: [0002] With the rapid development of my country's aerospace industry, advanced aircraft projects have begun to be developed, such as China's C919 large passenger aircraft project. These aerospace projects have put forward higher requirements for electronic components. At present, the advanced nature of composite materials has been introduced internationally. To solve the harsh requirements of aerospace on weight and other performance, for wire and cable, a new material: polyimide / PTFE composite film is used as insulation material for wire and cable. [0003] The insulation of this series of conductors is made of polyimide / PTFE film composite film material in the inner layer, and PTFE raw material tape in the outer layer. These two materials are wound ...
