Brazing procedure integration device

Abstract

The invention discloses an integral device for a braze welding technique, which includes a braze welding furnace and a quenching furnace; the discharge opening of the braze welding furnace and the feed opening of the quenching furnace are connected by a seal connection part which is provided with a strobe mechanism. In the invention, based on the existing braze welding furnace, the quenching furnace is combined with the braze welding furnace, thus realizing that the whole technical processes of braze welding, quenching and cooling are carried out in an closed environment with protection atmosphere; the welding lines of workpieces are tight and uniform with a smooth surface, thus not only simplifying the production technique, saving the working time, improving the production efficiency, but also reducing the manual working intensity and saving a workshop space. The integral device has the advantages of novel structure, high automatization degree, simple operation and wide application range.

Description

technical field [0001] The invention relates to a brazing device for hard alloy, carbon steel and other materials, in particular to a brazing process integrated device. Background technique [0002] The welding method of wetting the base metal with liquid brazing material and filling the interface gap of the workpiece and making it diffuse with the base metal is called brazing. The method of heating and brazing the assembled workpiece in a brazing furnace is called furnace Brazing has the characteristics of overall heating, uniform heating, and small deformation of the workpiece. The heating device is a brazing furnace. [0003] At present, there are generally two types of brazing furnaces for brazing in domestic furnaces: one is a vacuum furnace, which uses the evaporation of metals and their oxides when heated in a vacuum to destroy the oxide film on the surface, so as to achieve the effect of removing the film, which can effectively Prevent the metal to be welded from be...

[0003] At present, there are generally two types of brazing furnaces for brazing in domestic furnaces: one is a vacuum furnace, which uses the evaporation of metals and their oxides when heated in a vacuum to destroy the oxide film on the surface, so as to achieve the effect of removing the film, which can effectively Prevent the metal to be welded from being oxidized; the other is a protective atmosphere furnace, in which the atmosphere gas is poured into the brazing furnace, and the gas is mostly reducing gas and inert gas, which can not only prevent the workpiece from being oxidized when it is heated, but also reduce the oxidation on the surface of the workpiece However, the above two brazing furnaces have the same disadvantages. The workpiece must be quenched after brazing to obtain better physical properties. However, the heating temperature in the brazing furnace is generally about 1200 degrees. After the workpiece is brazed, it needs to be placed in the brazing furnace to cool to a lower temperature before it can be released from the furnace to ensure that the workpiece is not oxidized, and then the workpiece is moved to the quenching furnace to raise the temperature to 800-900 degrees. The workpiece is moved to the quenching medium for cooling. The whole process is not only time-consuming, inefficient, and wastes energy, but also the workpiece will be damaged due to the influence of human factors during the transportation of the workpiece, or the workpiece will be oxidized due to incomplete cooling, resulting in Reduced workpiece quality
