Embodiment 1

[0054] The flux-cored electrode 8 includes a flux 802 and a brazing sheath 801 wrapped outside the flux 802. The brazing flux 802 is usually powder or particles including various metals. The manufacturing process of the brazing sheath 801 is usually first made of copper, silver, The alloy ingot melted by zinc according to a certain ratio, after the alloy ingot is rough-turned to remove the scale and annealed, the alloy ingot is extruded into a brazing sheet strip by a horizontal extruder, and then the brazing sheet strip is multiplied. The second rolling forms a brazing filler metal strip, which can be used as the brazing filler metal sheath 801 of the flux cored electrode 8 .

[0055] After preparing the solder sheath 801 of the flux-cored electrode 8 and the brazing flux 802, it can be used as Figure 1 to Figure 3 The shown flux-cored electrode preparation equipment prepares a flux-cored electrode 8, and the flux-cored electrode preparation equipment includes an unwinding d...

Abstract

The invention relates to the field of flux-cored electrodes, in particular to a preparation method and device of a flux-cored electrode. The invention aims to protect a brazing flux melting injection device and a preparation method and preparation equipment of a flux-cored welding rod. The soldering flux melting injection device comprises a soldering flux container, a spiral conveying piece and an injection pipe, the injection pipe is provided with an injection pipe inlet and an injection pipe outlet, and the soldering flux container is provided with a container inlet and a container outlet; a spiral channel is arranged on the spiral conveying piece, and the spiral conveying piece extends into the injection tube and / or the brazing flux container; the soldering flux melting and injecting device further comprises a conveying part driving mechanism and a heating device for heating and melting the soldering flux in the injection pipe, and the spiral conveying part applies acting force to the soldering flux through rotation so that the soldering flux can be conveyed to an outlet of the injection pipe, and the melted soldering flux can be extruded out of the outlet of the injection pipe. When the brazing flux melting injection device is used, no organic adhesive is used, and the technical problem that the organic adhesive is prone to causing damage to the body health of production personnel is solved.

Description

technical field [0001] The invention relates to the field of flux-cored electrodes, in particular to a preparation method and device for flux-cored electrodes. Background technique [0002] Flux-cored electrodes are widely used in brazing in the fields of aerospace, automobiles, machinery, and household appliances. Flux-cored electrodes include flux and a brazing material sheath wrapped outside the flux. The Chinese invention patent application publication number CN103480988A discloses a A high-tin silver-based welding rod and a preparation method thereof, the preparation method is as follows: first atomize copper and tin into alloy powder according to a certain proportion as a flux, then melt silver, copper, and zinc into an alloy ingot according to a certain proportion, and the alloy ingot is thickened After the car pulls off the skin and anneals, the ingot is extruded into a brazing filler metal strip by a horizontal extruder, and the brazing filler metal strip is rolled ...
