Problems solved by technology

[0003] In order to solve the problem that the flame is too concentrated during the manual brazing process of thin-walled aluminum alloy and copper alloy waveguide, the parts will be heated unevenly, resulting in deformation, and at the same time, the parts are prone to overburning and the overall heating speed of the parts is also slow. The invention provides a combined porous welding tip for manual brazing of thin-walled aluminum and copper alloy waveguides

Abstract

The invention relates to a combined type multihole welding tip for manual brazing of thin-walled aluminum and copper alloy waveguide tubes. The combined type multihole welding tip consists of a welding tip connector and a spraying sleeve, wherein a spraying hole is formed in the welding tip connector in the axial direction; more than four diffusing holes are formed in the welding tip connector in the radial direction; one end of each diffusing hole is connected with the spraying hole; more than four flow distributing grooves are uniformly formed in an outer cylindrical surface of the welding tip connector; the other end of each diffusing hole is connected with the corresponding flow distributing groove; the spraying sleeve sleeves the welding tip connector; a port of the spraying sleeve is a spraying cavity; and a port of the spraying hole of the welding tip connector is correspondingly positioned in the inner port of the spraying cavity. By the combined type multihole welding tip, a piece of sprayed flame can be changed into a plurality of pieces of sprayed flame, the heated area of a part is increased, and the overall heating speed of the part is increased three times to five times; the straightly sprayed flame can be changed into diffused fan-shaped flame, and the part can be heated uniformly and cannot deform; and the combined type multihole welding tip is used for manual brazing of the thin-walled aluminum and copper alloy waveguide tubes with the thicknesses of 1mm-4mm, and overburning of the part can be avoided.

Description

technical field [0001] The invention belongs to the technical field of manual brazing, in particular to a waveguide welding device for welding thin-walled aluminum alloys and copper alloys with a thickness of 1mm to 4mm. Background technique [0002] Waveguide microwave devices are mainly divided into aluminum waveguides and copper waveguides. This type of waveguide is drawn and formed, and the hollow wall thickness is only between 1-4mm, which is a typical thin-walled part. This type of parts and the two flanges are manually brazed to form a waveguide microwave device. As we all know, brazing is a kind of use of a metal with a lower melting point than the base metal as the solder, heating the weldment and the solder to a temperature higher than the melting point of the solder and lower than the melting temperature of the base metal, and using the liquid solder to wet the base metal and fill the joint And interdiffusion with the base metal to realize the method of connecti...
