The method comprises the following steps: (1) welding materials, welding agents and an inductor are selected; (2) the blade is placed in the inductor, the position of the blade is set right, and the welding agents are placed; (3), materials to be welded are completely melted and completely flow to the bottom face of a gap, according to the design requirement of the blade, the position of the blade is adjusted, the blade is compressed, and the welding line gap is kept between 0.05 mm to 0.10 mm; (4), a cutter body and the blade are evenly heated to 900 DEG C to 950 DEG C at the heating speed lower than 200 DEG C/S and are kept for 3S at the temperature, and it is ensured that a welding line is evenly filled with the welding materials in a flowing manner; (5) the cutter body and the blade are cooled to 300 DEG C to 350 DEG C, and heat preservation is carried out on the cutter body and the blade in a heat preservation box for one hour to three hours. Dehydration borax and boric acid are adopted in the welding agents, and the mixed ratio of the dehydration borax to the boric acid is 7:3. Through the technology, especially for control over the highest temperature of 1000 DEG C, the rising rate and the cooling heat preservation temperature, the welding reliability of the hard alloy cutter blade of the tool is greatly improved, and the quality of the welding tool is greatly improved.
Description
Technical field
The invention belongs to composite plate weld processing technique field is and in particular to a kind of welding of carbide tool blade adds
Work method.
Background technology
In recent years, with the popularization and application of new material such as titanium alloy, composite, process the cutter of these new materials
Propose requirement more, the cutter processing these materials typically all selects the cutter of carbide blade welding, hard alloy
Blade many kinds numerous trade mark such as y330, ys8, yt15, yg8, ys6, yw1, yw2, solder also has many types, copper bar, Rhizoma Humatae Tyermanni,
Special material etc., maximum temperature controls difference does not have corresponding temperature standard according to the blade material trade mark and solder yet, if
Temperature is too high to cause blade burning, and solder evaporation was lost efficacy.During welding, the heating rate of high-frequency apparatus does not have corresponding standard yet,
The parameter that after welding, the cooldown rate of product does not respond to yet.Above problem can affect ruggedness and the service life of cutter,
Will also result in the crackle of cutter, collapse tooth, when serious, easily cause the direct fragmentation of blade, and then affect to produce.
Content of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of cutanit blade welding processing side
Method, using this welding processing, ensure that carbide tool welding quality.
The purpose of the present invention is achieved through the following technical solutions:
The welding processing of carbide tool blade is it is characterised in that step is as follows:
(1) solder, solder flux and induction apparatuss are selected；
(2) blade is placed in induction apparatuss, ajusts blade position, and place solder flux；
(3) it is completely melt, behind the full gap bottom surface of cocurrent, by insert design requirement, to adjust blade position and compress knife after solder
Piece, keeps weld gap between 0.05mm～0.10mm, does not have discontiguous area between weld seam and solder；
(4) cutter hub and blade are uniformly heated between 900 DEG C～950 DEG C with the firing rate less than 200 DEG C/s, and here
Keep the 3s time in temperature；Ensure solder uniform flow full weld seam；
(5) it is incubated 1～3 hour in 300 DEG C～350 DEG C couveuses of chilling temperature.
Described solder flux selects dewatering borax and boric acid；Mixed proportion: dewatering borax: boric acid=7:3.
Chip position diameter when cutterCutter groove length l >=15mm；Flux flow depth is at least up to knife
2/3rds of groove depth, length is 4/5ths.
Beneficial effects of the present invention: by process above, during high-frequency welding carbide blade, select optimal intensification speed
200 DEG C/s of rate, it is to avoid the crackle that blade causes because of the thermal stress that the thermograde that thermal coefficient of expansion causes produces；High-frequency welding
Afterwards, it is incubated using 300 DEG C of resistance furnaces in cooling procedure, reduce because rapidly cooling produces the crackle that thermal stress causes.To highest
The control that 1000 DEG C of temperature, heating rate, cooling holding temperature control, greatly improve cutanit blade welding can
By property, greatly improve the quality of brazed shank tool.
Specific embodiment
The welding processing of carbide tool blade, its step is as follows:
(1) solder, solder flux and induction apparatuss are selected, solder is h62 brass wire, solder flux selects dewatering borax and boric acid；Mixing
Ratio: dewatering borax: boric acid=7:3；
(2) blade is placed in induction apparatuss, ajusts blade position, and place solder flux；
(3) it is completely melt, behind the full gap bottom surface of cocurrent, by insert design requirement, to adjust blade position and compress knife after solder
Piece, keeps weld gap between 0.05mm～0.10mm, does not have discontiguous area between weld seam and solder；Ensure heated blade trench bottom
And not making blade burning, the section of induction apparatuss is suitable with the size of part to be welded；
(4) cutter hub and blade are uniformly heated between 900 DEG C～950 DEG C with the firing rate less than 200 DEG C/s, must not surpass
Cross 1000 DEG C, and keep the 3s time in this temperature；Ensure solder uniform flow full weld seam；
(5) it is incubated 1～3 hour in 300 DEG C～350 DEG C couveuses of chilling temperature.
Chip position diameter for cutterThe product of cutter groove length l >=15mm is it is desirable to flux flow is deep
More than 2/3rds of cutter groove depth, length is 4/5ths for degree (stream amount of copper depth).Length is more than 90% (along backrest
Face) but front edge is forbidden stream copper.Chip position diameter for cutterThe product postwelding of long l >=500mm is warm immediately
School.
