Abstract
The present invention relates to a technology for preparing three-section conductive wires used for manufacturing electron guns. Firstly, the outer leading wire of the three-section conductive wire is made from 0.05 to 0.1% of carbon, 0.2 to 0.4% of manganese and 99.5 to 99.75% of nickel according to weight percentage and conventional technology. Secondly, the present invention adopts resistance welding with 2 to 5V voltage and 0.23 to 0.64 KA current to weld an inner leading wire 3 with one end of a magnesium wire 2 as integration, and adopts resistance welding with 5V voltage and 0.23 to 0.36 KA current to weld the outer leading wire 1 with the other end of the magnesium wire 2 as integration. Because the present invention adopts pure nickel as the materials of an outer tubular needle, and the welding mode of the three-section conductive wire adopts resistance welding, the present invention solves the problem of poor welding in the process of manufacturing the three-section conductive wire by changing the materials and the welding mode of the outer leading wire of the three-section conductive wire, lowers the incidence rate of the poor emission of picture tubes, and greatly reduces production cost. The processing technology of the outer leading wire is simple.
Description
Technical field
The present invention relates to the preparation technology of a kind of electron gun manufacturing with three-section guide wire.
Background technology
Each metal electrode of forming electron gun is sealed in the emission of carrying out electron beam in the chromoscope of vacuum.Electrode adds the effect that can play lens behind the voltage, and electron beam is focused on and assembles.The effect of three-section guide wire is exactly to keep the conducting of electricity between chromoscope internal electrode and external circuit, promptly applied voltage to be imported on the sealed electrode.Electron gun is made used three-section guide wire and is made up of external tube needles, Dumet wire, lead three parts, by welding this three part is linked together.The external tube needles of three-section guide wire is the composite material of steel surface nickel plating at present.The production process of external tube needles is as follows: earlier the carbon steel metal line is cut into the length that meets technological requirement, adopt electric plating method to carry out nickel plating on the carbon steel metal line with nickel sulfate solution then, carry out annealing in hydrogen atmosphere and polishing at last.The purpose of plating nickel on surface is to guarantee that external tube needles has welding performance preferably.The key point of nickel plating is the control of concentration of nickel sulfate and nickel plating time, but nickel coating is very thin, be in the scope of technological requirement THICKNESS CONTROL, and technical difficulty is bigger, occurs the situation of the even thickness ultra-specification of uneven coating easily.If nickel coating is defective, easily produce weak weldering in when welding, thereby occur in picture tube that bobbin comes off and not conducting of electron gun stem stem etc. bad, also higher to the cost that nickel coating thickness detects.So it is big to carry out process complexity, the technical difficulty of plating nickel on surface on composite material, the production cost height.The mode of arc welding is adopted in the welding of seal wire at present, and arc welding is connected to following shortcoming: it is many to splash, and the weldingvoltage height can't be realized computer control, the cost height.
Summary of the invention
The object of the present invention is to provide and a kind ofly can improve weld strength, it is bad to reduce weak weldering, can simplify the outer lead processing method again, and the electron gun manufacturing that reduces production costs is with the preparation technology of three-section guide wire.
For achieving the above object, the preparation method that the present invention adopts is: at first will contain mass percent according to common process is the outer lead that the nickel of 0.05～0.1% carbon, 0.2～0.4% manganese and 99.5～99.75% is made three-section guide wire; Employing is 2～5V at voltage, and electric current is that the electric resistance welding of 0.23～0.64KA is welded as a whole an end of lead and Dumet wire; Employing voltage is 5V, and electric current is that the electric resistance welding of 0.23～0.36KA is welded as a whole the other end of outer lead and Dumet wire.
Outer lead of the present invention and Dumet wire are 2.0～3.5Kg at welding time institute's plus-pressure.
Because the present invention adopts the material of pure nickel as external tube needles, and the welding manner of three-section guide wire is an electric resistance welding, by change to three-section guide wire outer lead material and welding manner, solved the weak weldering problem that occurs in the three-section guide wire manufacture process, reduced the acomia bad incidence of picture tube, and the outer lead processing technology is simple, reduces production costs greatly.
