The invention discloses a brazing filler metal ingot brazing flux feeding device for a seamless flux-cored wire. The device comprises a base arranged on a platform, wherein a lower base is arranged atthe bottom of the base, the lower base is provided with a cylindrical ingot seat, the ingot seat can simultaneously rotate and move in an up-down reciprocating mode and in the vertical direction, theingot seat is internally provided with an ingot which moves synchronously with the ingot seat, and a cylindrical working cavity used for containing brazing filler metal is formed in the upper portionof the ingot; and an upper base is arranged on the upper portion of the base, the upper base is provided with a cylindrical pressing rod which is arranged opposite to the working cavity and can simultaneously rotate and move in an up-down reciprocating mode and in the vertical direction, at least one brazing flux feeding groove is formed in the peripheral surface of the pressing rod, and at the same time that the pressing rod rotates and moves downwards linearly, brazing filler metal enters the working cavity along with the brazing flux feeding groove in the pressing rod. According to the device, the brazing filler metal is convenient to add, the distance between the plane of the brazing filler metal and the base is kept unchanged, so that the compaction density of brazing flux is ensured, and then uniform components of a flux-cored part in the prepared flux-cored wire are ensured.
