A brazing ingot powder loading device for seamless flux-cored wire

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of seamless flux-cored wires, in particular to a brazing ingot powder loading device for seamless flux-cored wires. Background technique [0002] The preparation steps of flux-cored wire are generally that the solder alloy is refined to make a solder ingot; the solder ingot is made into a filamentary solder by hot extrusion, hot rolling and hot drawing, and the filamentary solder can be made into It can be made into various specifications of brazing wire, brazing straight wire and brazing ring. For the production of the existing seamless brazing wire, one of the necessary steps is: casting an ingot of metal solder with an open end and a cavity, and placing the opening horizontally upwards on a plane; Add flux in the middle, while adding flux, use the pressure head moving up and down to compact the flux until the flux is installed at the preset position; the ingot filled with flux is then extruded and drawn ...

AI Technical Summary

Problems solved by technology

This method of filling and compacting the flux has many disadvantages: with the increase of the flux in the ingot, the downward travel of the indenter will gradually become shorter, and it is necessary to continuously adjust the stroke of the indenter. Inconsistent adjustments or different weights of flux loaded into the cavity of the ingot each time will easily cause differences in the compaction density of the flux, which will result in uneven composition of the flux core in the prepared flux-cored wire; in addition, if the indenter If the size is too large, it is inconvenient to add brazing flux. It is necessary to take out the indenter and put the brazing flux, and the work efficiency is low; if the indenter size is too small, the flux is not easy to compact during the compaction process.
