Abstract
The fabrication process comprises: 1) metallizing two planes of the ceramic support; 2) cleaning up the ceramic support; 3) coating the copper / silver soldering on the metallized layer; 4) making sintering treatment for the copper/silver soldering coated on the metallized layer; 5) cooling the sintered ceramic support; 6) making welding for joining the ceramic support with the shell of tube.
Description
1, technical field:
The present invention is a kind of manufacture method of vacuum-tube cathode assembly, belongs to the innovative technology of vacuum-tube cathode assembly manufacture method.
2, background technology:
In the vacuum tube of existing magnetron, the structural representation of making vacuum-tube cathode assembly as shown in Figure 1, when vacuum tube shell 2 welds with ceramic supporting element 1, usually adopt two planes of ceramic supporting element 1 to carry out metalized, an end welds with silver-bearing copper weld tabs 3 and shell 2 then.The welding method of this employing weld tabs, because weld tabs processing technology complexity, so the cost of manufacture height; In addition, when assembling, increase the operation of putting weld tabs, reduced production efficiency; In addition, if the position that weld tabs is put words devious, shell 2 can be eccentric with ceramic supporting element 1 during welding, influences welding effect.
3, summary of the invention:
The objective of the invention is to overcome above-mentioned shortcoming and provide a kind of processing technology simple, cost is low, reduces assembling procedure during assembling, helps enhancing productivity, and realizes the manufacture method of the vacuum-tube cathode assembly of automated production easily.
The structural representation that the present invention makes vacuum-tube cathode assembly includes following steps as shown in Figure 2;
1) metalized is carried out on two planes of ceramic supporting element (1);
2) ceramic supporting element (1) is cleaned;
3) metal layer to two planes of ceramic supporting element (1) applies brush copper silver paste (4);
4) the deposited copper silver paste (4) of brushing of the metal layer of ceramic supporting element (1) is carried out sintering processes;
5) ceramic supporting element behind the sintering (1) is cooled off;
6) ceramic supporting element (1) after will handling well and shell (2) welding.
Above-mentioned steps) thickness of the copper silver paste (4) of the deposited brush of ceramic supporting element (1) metal layer is 0.05～0.2mm.
Above-mentioned steps 4) adopt 300～800 ℃ under the hydrogen environment protection, to carry out sintering processes.
Above-mentioned steps 5) adopt the mode of slowly cooling to cool off to the ceramic supporting element behind the sintering (1).
The present invention is owing to adopted the metal layer at ceramic supporting element to apply brush copper silver paste, and the copper silver paste carried out sintering, the technology that cooled ceramic supporting element and shell are welded, so its processing technology is simple, cost is low, can reduce assembling procedure during assembling, helps enhancing productivity, also avoided putting the trouble of weld tabs, realized automated production easily with manual type.The present invention is the manufacture method of a kind of easy to operate, simple and practical vacuum-tube cathode assembly.
