Description

Brazing processing tool

Technical Field

The utility model relates to a processing frock specifically is a processing frock of brazing.

Background

Aluminum brazing refers to a welding method in which brazing filler metal lower than the melting point of an aluminum piece and a weldment are heated to the melting temperature of the brazing filler metal at the same time, and then the liquid brazing filler metal is used for filling gaps of a solid workpiece to connect metals. During brazing, an oxide film and oil stains on a contact surface of a base material are removed firstly, so that a capillary tube can play a role after the brazing filler metal is melted, the wettability and capillary fluidity of the brazing filler metal are increased, and the aluminum brazing is characterized in that:

1. small deformation, clean joint surface, good air tightness, stable shape and size, higher preparation requirement before brazing, and suitability for welding components which are precise, complex and composed of different materials. 2. The brazing filler metal is melted but the weldment is not melted, the brazing filler metal is made of alloy with the melting point lower than that of the base metal, the brazing filler metal is melted when heated, the brazing filler metal is filled and kept in a joint gap by virtue of the wetting action and the capillary action, the base metal is in a solid state, and the brazing filler metal and the solid base metal are connected after being mutually diffused. The brazing has small influence on the physical and chemical properties of the base metal, and the welding stress and the deformation are small. 3. The welding device can realize multilayer and multi-channel welding, and can ensure that the channels cannot be mutually connected, thereby being applied to more complex parts with multiple air channels, water channels and multilayer distribution of semiconductors.

Two big faces exert pressure about when brazing, and the inflation can lead to empty position degree to change to extending to both ends under high temperature, and the part of multichannel brazing, the part opening is many, and the open end does not have sealed pad moreover, can cause unable sealed when the edge leakage, causes the erroneous judgement to the test seepage of part, and the product that the terminal surface is thinner, internal pressure can be with the ejecting deformation of end cover when the pressurization test. Therefore, the brazing processing tool is improved.
