Description
Technical field
The utility model is related to brazing equipment field, for chemical tool blade and matrix material to be welded, specifically
It is related to a kind of light wave soldering oven.
Background technology
Machine cutting tool, also referred to as machine tool or machine tool, are the indispensable instrument of metal cutting process, particularly high-end essence
Close processing, specific alloy material processing cutting element used, traditional hard alloy cutter, instrument steel cutter are progressively cut
Cut the more high-end whisker ceramics of performance, ceramic tool substitution.The processing cutting ability of sintex is better than conventional tool, but
The cost price of sintex is also above conventional tool simultaneously.Sintex is typically, using ceramic material as blade, to be welded on
On matrix material, chemical tool is constituted, matrix material is generally the Hardmetal materials currently used as instrument, such as tungsten and molybdenum material.
The welding quality of sintex is directly connected to the performance, service life and the processing benefit using sintex of cutter.
Ceramic material, tungsten and molybdenum material fusing point it is very high, it is impossible to directly welded using melting method, but use solder melting to glue
The method connect is welded.The fusing point of solder is relatively low, and the solder of melting all has preferably profit to ceramic material and matrix material
It is moist, ceramic tip and matrix material can be bonded together after solder cooling and solidifying, and there are enough bond strengths.Therefore
Soldering processes and brazing equipment are most important to the performance of sintex.
Common material soldering is generally two kinds of same metal materials or two kinds of different Metal Material Weldings, weldment material
Thermal conductivity is high, similar thermal expansion coefficient, it is and also quite similar to the compatibility of solder.Further, since metal material is in itself
Thermal conductivity factor is high, easily welding temperature uniformity is realized during welding, if using electromagnetic induction heating, the electromagnetic coupled of material
Kelvin effect is also consistent, can realize the synchronous heating of weldment.And the soldering of ceramics and carbide matrix material is completely not
With.First, ceramic thermal conductivity is less than carbide matrix material, therefore their heat conduction velocity is different, specific heat difference
Greatly, during welding for ensure they synchronously heating, temperature uniformly need special computer heating control technique.Secondly, ceramic material heat is swollen
Swollen coefficient is low, big with matrix material expansion coefficient difference, when being welded with matrix material, there is very big stress in soldering land
Gradient is, it is necessary to overcome thermal stress caused by the thermal expansion coefficient difference of welding material, and the thermal stress that soldering is produced can reduce connection
Intensity, quality are difficult to meet needs, it is therefore desirable to special brazing material and welding procedure.General brazing material exists to ceramics
Ceramics are not infiltrated after metallurgical incompatibility, i.e. brazing filler metal melts, it is difficult to realize interatomic metallurgical binding in welding area and ceramics.
The solder of ceramic welding is usually needed by adding active element to improve wetability of the solder in ceramic surface, is added as used
Plus the method for cushion solves unmatched problem of cermet physical property etc..Ceramic brazing typically selects soft, hard double-layer bumper
Layer.The thermal coefficient of expansion of soft cushion is higher, can solve thermal expansion and mismatch caused residual stress, rigid cushion
Bond strength is higher, solves weld strength.So Ceramic brazing requires vacuum or vacuum inert gas atmosphere, temperature is high, temperature control
Complex process is, it is necessary to control the volatilization of soldering auxiliary agent, the melting of cored solder and the infiltration of weldment and solidification.
The Chinese invention application of Application No. 200710021617, discloses a kind of tool made of superhard material method for welding and sets
Standby, using quartz cover body of heater, mode of heating is electromagnetic induction, and induction coil is placed in the outside of quartz cover, and weldment is placed in quartz cover
On interior pallet, pallet is rotatable.Equipment is without vacuum system, and the inert atmosphere in stove rushes argon gas, quartz cover top using bottom
The mode for the steam vent exhaust displacement opened replaces the air in stove with argon gas, makes to turn into inert atmosphere in stove, it is clear that this side
Formula is difficult to reach the purpose of hypoxic atmosphere.The method for welding that the patent application is proposed is mainly used in process for un-metal material purpose
Cutting blade and polishing emery wheel, requirement during this kind of tool made of superhard material soldering to atmosphere is not very strict, therefore the invention
There is no vacuum system in equipment.The method and apparatus of the patent application is not suitable for the soldering of lathe sintex.

The technology is provided with radome in body of heater, and using radome as sensing heating body, high-frequency electromagnetic induction circle enters to radome
Row sensing heating, then the heat radiation heating soldering workpiece for passing through radome.The technology is characterized in that the traditional electromagnetic induction of change is straight
The pattern to soldering work piece sensing heating is connect, but by electromagnetic induction heating radome, raises radome temperature, as height
Warm radiant heat source, heat radiation heating soldering workpiece.Although this kind of mode of heating avoid pricker when electromagnetic induction directly heats workpiece
The temperature difference for the soldered elements that the difference of weldering element electromagnetic induction kelvin effect is brought, while directly sensing heating also is difficult to control
The stability of brazing temperature and temperature processed, can influence the uniformity and stability of brazing property.But the mode of heating class of the technology
Resistance heating element heating is similar to, is heat radiation heating, infrared source is simply changed to electromagnetic induction heating by resistance heating,
But all there is heat transfer efficiency bottom, the problem of temperature control response speed is slow is unfavorable for uniform, fast and stable brazing temperature.It is heavier
Want, this heat radiation mode of heating, it is necessary to well heat-insulation layer, to improve the thermal efficiency.In addition, this hot spoke of electromagnetic induction
The temperature conditionss that mode of heating is penetrated for soldering are restricted, if radome is metal material, metal material electromagnetism during high temperature
Kelvin effect declines, the reduction of sensing heating efficiency, the limitation of softening temperature while metal material is originally experienced, it is also difficult to obtain higher
The radiant heat source of temperature.If shielding material selects graphite material, although can obtain very high radiant heat source, but during high temperature
The scaling loss of graphite and volatilization will influence furnace brazing atmosphere, and the carbon particularly volatilized is often all unfavorable to brazing property
's.
The Chinese invention patent of Application No. 201310090962, is disclosed one kind and is added using the quartzy integrated radiation of metal
The vacuum brazing furnace of hot device, using the quartzy heating plate of the integrated metal of infrared radiation type as calandria, carries out vacuum inert gas
The equipment that body protects soldering.Described according to specification, the vacuum brazing furnace structure of the invention is from outside to inside successively including stainless steel
Surveyed and stove in the quartzy heating plate of shell, metal ring insulation board, inner side drum, metal, bell, stainless steel casing (furnace shell) bottom
Surveyed in lid and be evenly equipped with refractory brick, accordingly in the invention soldering oven, insulation pattern is that furnace body inside face hides heat for metal ring

Gas can not take off at normal temperatures, after furnace temperature is raised, and have degassing phenomenon, influence welding performance, be completely unsuitable for potter
The welding of tool.In addition, second deficiency of the technology is that the quartzy heating plate of heater element metal is fragile, change complicated.Due to
Metal quartz heating plate is in the high-temperature region surveyed in stove inside holding thermal insulation layer, when the higher brazing member of welding brazing temperature, stone
Quartz glass devitrification after crystallization, crystallization occurs for Ying Yi, and because crystallization expansion causes quartz glass microgroove occur
Breakage, heating element heater failure.3rd deficiency of the technology is to use refractory brick to make heat-insulation layer in stove, can greatly prolong soldering oven
The heating, cooling time, reduce soldering efficiency.It is resistance to because refractory brick thermal conductivity factor is low, specific heat capacity big, therefore during stove heating
Firebrick needs a large amount of heat absorptions, consumes substantial amounts of heat, and because thermal conductivity factor is low, reach that heat balance time is also longer.And work as
When stove cools after the completion of soldering, because thermal conductivity factor is low, refractory brick internal heat is slow to surface conduction of velocity, therefore influence stove
Interior cooling rate.Therefore, the soldering oven heating, cooling speed for making heat-insulation layer using refractory brick is slow, influences equipment service efficiency,
Be not suitable for the requirement of the quick brazing operation of industrialization.The 4th deficiency of the technology is 5 pumped vacuum systems of its claim the, is pressed

Empty, middle vacuum, high-vacuum apparatus form multistage unit.Usual lobe pump belongs to medium vacuum equipment, and its prime should also be furnished with
Backing pump, such as vacuum mechanical pump, separate unit lobe pump are can not to complete the process from initial vacuum to middle vacuum.For chemical tool
Soldering, furnace atmosphere requires very strict, and the vacuum of equipment, which is usually required that, reaches high vacuum or ultra-high vacuum levels, therefore should
Equipment can not meet the requirement of chemical tool soldering.In addition, the afterbody gas gathering system proposed in the claim and specification, is adopted
It will be reclaimed with lobe pump in stove in cooling circulation argon gas feeding argon bottle.This claim is technically infeasible
