Abstract

The invention provides an assembly process of adie assembly. The assembly process comprises the following steps of S1, assembling, namely assembling a cathode assembly, assembling an anode assembly and assembling an exhaust pipe assembly; S2, assembling the die assembly, namely assembling the assembled cathode assembly, anode assembly and exhaust pipe assembly together to form the die assembly; and S3, assembling the die assembly and other assemblies to obtain a magnetron finished product, wherein the assembly of the die assembly comprises pressing a magnetic pole K side, connecting the anodeassembly and the magnetic pole K side and then pressing; pressing the cathode, and assembling the cathode assembly and the anode assembly together; after the cathode is pressing, assembling the anodeassembly and the exhaust pipe assembly together to form the die assembly, and welding overall; carrying out leak detection and exhaust operations on the die assembly, removing an oxide layer of the anode assembly, and installing an antenna cap; deburring and aging. The assembled die assembly has the advantages of no damage to each component, high yield, no crack, no leakage hole, and tight weldingbetween the assemblies.

Description

technical field [0001] The invention relates to the technical field of magnetrons, in particular to an assembly process of a tube core assembly. Background technique [0002] A magnetron is an electric vacuum device used to generate microwave energy. Under the control of the perpendicular constant magnetic field and constant electric field, the electrons in the tube interact with the high-frequency electromagnetic field to convert the energy obtained from the constant electric field into microwave energy, thereby achieving the purpose of generating microwave energy. The core element of the magnetron is a die assembly, and the die assembly includes a cathode assembly, an anode assembly and an exhaust pipe assembly. [0003] The cathode assembly, the emitter of electrons, is also an integral part of the interaction space. The anode assembly is made of metal material with good electrical conductivity and has multiple resonant cavities. The higher the frequency of the magnetr...
