[0071] figure 1 This is a schematic structural diagram of the device for preparing flux-cored brazing filler metal provided in the embodiment of the present invention. like figure 1 As shown, the device for preparing flux-cored brazing filler metal provided in this embodiment includes a conveying unit, a rolling unit, a powder-removing unit, a flux filling unit and a drying unit 6 .
[0072] The conveying unit includes an unwinding device 1, a rewinding device 7 and a guide roller group; the rolling unit includes a rolling roller 2 and a pressing roller 4; the flux filling unit includes a stocker 5, and the The side wall of the stocker 5 is provided with a wire inlet 51 and a wire outlet 52 .
[0073] The unwinding device 1, the rolling roll 2, the pressing roll 4, the wire inlet 51, the guide roller group, the wire outlet 52, the drying unit 6 and the winding device 7 are arranged in sequence; the powder discharging unit 3 is arranged in the Between the rolling roll 2 and ...
Embodiment 1
[0086] The present embodiment provides a preparation method of flux-cored brazing material, comprising the following steps:
[0087] (1) The BAg49Cu16Zn23Ni4.5Mn7.5 solder strip with a width of 8mm and a thickness of 0.22mm is sent to the rolling roll by the unwinding device, and rolled by the rolling roll to form a U-shaped solder strip;
[0088] (2) The U-shaped solder tape is transported to the lower powder unit, and the solid flux QJ102 is added to the U-shaped solder tape according to the ratio of the flux to the mass ratio of the flux to the U-shaped solder tape is 10%; The U-shaped solder tape of the flux continues to be transported to the pressing roller for pressing treatment to form the joint flux core brazing material;
[0089] (3) The butt seam flux-cored brazing filler metal is fed into the stocker containing the liquid flux QJ102 through the wire inlet, and guided by the guide roller set to make the butt seam flux-cored brazing filler metal immersed in the liquid...
Embodiment 2
[0094] The present embodiment refers to the preparation method of embodiment 1, and the difference is only:
[0095] The solder tape is BAg30CuZnSn, and the flux is QJ101.
