Problems solved by technology

[0003] The original process is: three sets of products are welded in one furnace; the solder tabs are made by hand, because the solder tabs are very brittle, not only the production speed is slow, but also the solder tabs are prone to breakage during the manual production process; during the assembly process The solder tabs made by hand are not easy to assemble and are easy to break, resulting in repeated assembly and low assembly efficiency
The traditional assembly sequence is: put the solder tabs on the

Abstract

The invention provides a vacuum brazing method for a radio fuze antenna radiator. The vacuum brazing method comprises the following steps: 1) preparing a soldering lug by adopting a linear cutting mode; 2) assembling a cavity and a cover plate of the radiator according to requirements; 3) designing a welding process box and a welding tool, putting the assembled radiator into the process box, and then, putting the process box onto the welding tool which is put into a vacuum furnace in advance; 4) carrying out vacuum brazing on the radiator; and 5) carrying out thermal treatment on the brazed radiator. According to the vacuum brazing method, the soldering lug is prepared by adopting the linear cutting mode, so that break-off is avoided, and the time is saved; the soldering lug is fixed by four locating pins on a welding step, and the vacuum welding tool is supplemented, so that the welding defects of uneven welding flux filling, soldering skips and the like are greatly avoided, and the apparent mass is improved; according to the optimized process, a thermal treatment process is independent, thereby shortening the vacuum brazing and cooling time, and greatly improving the vacuum brazing efficiency.

Description

technical field [0001] The invention relates to the technical field of vacuum brazing, in particular to a vacuum brazing method for a radio fuze antenna radiator. Background technique [0002] The radiator is an important component of the radio fuze antenna, which is formed by vacuum brazing of the cavity, the welding piece and the cover plate. The microwave transmission channel is formed by its connection with the cable, and its main function is to receive, transmit and transmit signals. Therefore, the welding quality of the radiator directly affects the electrical performance and parameters, and determines the accuracy of signal transmission. [0003] The original process is: three sets of products are welded in one furnace; the solder tabs are made by hand, because the solder tabs are very brittle, not only the production speed is slow, but also the solder tabs are prone to breakage during the manual production process; during the assembly process The solder tabs made by...
