Embodiment Construction

[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0036] Such as figure 1 Shown, the preparation method of a kind of metal-based complex shape foil-shaped brazing filler metal of the present invention, comprises the following steps:

[0037] Step 1: If figure 2 As shown, take a plurality of metal-based foil-shaped solders, and clean and pretreat all metal-based foil-shaped solders;

[0038] Step 2: If image 3 As shown, all the processed metal-based foil-like solders are subjected to slow-moving precision wire cutting;

[0039] Step 3: If Figure 4 , 5 As shown, all metal-based foil-shaped solders after cutting are cleaned to obtain metal-based foil-shaped solders that can be separated into single pieces and have a clean surface.

[0040] A method for making...

Abstract

The invention relates to a manufacturing method for metal-based foil-like brazing filler metal in a complex shape. As a low-speed feeding and precise wire cutting mode is adopted, the metal-based brazing filler metal with the clean surface can be obtained by means of surface treatment on the brazing filler metal, preparation before wire cutting, precise wire cutting, and brazing filler metal cleaning after wire cutting, wherein the metal-based brazing filler metal can be separated singly. The manufacturing method for the brazing filler metal is high in efficiency, good in repeatability and good in structural adaptability, the brazing filler metal of a complex structure can be manufactured, and the manufacturing method can be widely used for replacing a current manual operation mode.

Description

technical field [0001] The invention relates to a method for making metal-based complex-shaped foil-shaped solder. Background technique [0002] The advantages of furnace brazing are the ability to braze large quantities of components at a low unit cost. For parts with complex shapes and high-precision requirements, the solder brazed in the furnace needs to be cut into the shape of the butt surface to prevent dimensional deviation caused by excess solder flowing. When brazing the aluminum alloy waveguide bridge in patent CN103433701A, the aluminum brazing filler metal is cut to make it match the two parts of the tailor-welded butt joint. Simple brazed mating surfaces. When the complexity of the structure increases, the brazing material of a certain shape is generally obtained by manual or engraving with a precision engraving machine. Carving solder is more precise than cutting solder, and can generally meet production requirements. However, if the solder is thick or has h...
