Abstract

The invention provides equipment for preparing filamentous BCu68NiSiB brazing filler metal into small ball brazing filler metal. A rotary table is located on the left side of a wire feeding mechanism, a straightening mechanism is arranged on the left side of a cutting mechanism, a ball milling system is located on the right side of the cutting mechanism, and a cleaning system, a sorting mechanism, a bright grinding mechanism, a vacuum drying system and a vacuum packaging system are sequentially arranged on the right side of the ball milling system. A method for preparing filiform BCu68NiSiB brazing filler metal into small-ball brazing filler metal comprises the following steps that bundle-shaped filiform brazing filler metal is cut into small brazing filler metal sections; ball-milling the small brazing filler metal sections into small balls; treating the primarily ground small balls into bright high-precision small balls; and finally, the dried brazing filler metal balls are poured into a vacuum packaging system to be packaged into bagged small-ball brazing filler metal. The method has the advantages that the BCu68NiSiB brazing filler metal ball is used for positioning brazing before brazing, green and efficient, existing flame brazing positioning and visual scribing positioning are replaced, and the pipeline manufacturing precision and positioning quality are improved.
