The device protects chamber, high temperature resistant bolt, leak protection air cushion circle, center post to constitute by hollow atmosphere. The utility model discloses enable the positive central point that the emery wheel is in furnace and put, enable metal base emery wheel and be heated in sintering process evenly, can let in protective gas, avoid the oxidation of metal binder at sintering process, make binder have good mechanical properties, this device simple structure can use with ordinary resistance furnace cooperation, has extended the application scope of ordinary resistance furnace.
Description
Technical field
This utility model belongs to emery wheel and manufactures field and in particular to a kind of metal base grinding wheel atmosphere sintering device.
Background technology
Metal base grinding wheel has effigurate carcass by metallic bond, abrasive material and additive mixing aftershaping, passes through
High temperature sintering becomes to have the bonded abrasive tool of certain bond strength.Typically it is made up of grinding wheel base body and abrasive material.Metal base grinding wheel passes
The sintering processing of system adopts resistance stove heat, and in resistance furnace, the only burner hearth left and right sides is distributed with resistance wire.Due to Metal Substrate sand
Between 750-1000 DEG C, metallic bond is oxidized easily in sintering wheel sintering temperature, and the performance of impact emery wheel typically should
Using gas-protecting sintering, but common resistance furnace does not have atmosphere protection measure.On the other hand, emery wheel is sintered using resistance furnace
When, emery wheel is positioned over resistance furnace bottom centre position and is heated, and at this moment emery wheel is in fire box temperature field temperature lower, emery wheel
A side contact with resistance furnace bottom surface it is impossible to the hard to bear Net long wave radiation to resistance wire causes the non-uniform temperature of whole emery wheel
Lead to burning, or produce underburnt phenomenon, thus affecting the performance of emery wheel.
Utility model content
The inequality of being heated causing for traditional emery wheel sintering processing, the easily oxidized problem of metallic bond, this practicality is new
Type aims to provide a kind of metal base grinding wheel atmosphere sintering device, can be with common resistance furnace using it is ensured that being heated when emery wheel sinters
Uniformly, prevent the oxidation of metallic bond, thus obtaining even tissue, mechanical property, installation capability and processing characteristics are good
Emery wheel.
Realize a kind of technical scheme of this utility model purpose: metal base grinding wheel atmosphere sintering device, by atmosphere protection chamber,
Leg, newel, high temperature resistant bolt, anti-gas-leak pad composition.Atmosphere protection chamber adopts symmetric design by high temperature resistant bolt connection.
First emery wheel central through hole is passed through newel, anti-gas-leak pad is placed in atmosphere protection chamber, and uses high temperature resistant bolt connection,
Mounted atmosphere protection chamber is uprightly positioned in the middle of burner hearth, accesses protective gas from the top air inlet hole in atmosphere protection chamber,
It is exhausted from the steam vent of bottom, be passed through protective gas and heated afterwards for a period of time.
Effect of the present utility model is: the metal base grinding wheel atmosphere sintering device being provided, and this device can make at emery wheel
In the center position of burner hearth, metal base grinding wheel can be made to be heated evenly in sintering process；Protective gas can be passed through, it is to avoid
Metallic bond, in the oxidation of sintering process, makes bonding agent have good mechanical property；This apparatus structure is simple, can with common
Resistance furnace use cooperatively, expanded the scope of application of conventional, electric-resistance stove.
Brief description
The metalloid base grinding wheel schematic diagram that Fig. 1 a, Fig. 1 b are suitable for for this utility model.
Fig. 2 is this utility model most preferred embodiment overall structure diagram.
Fig. 3 is this utility model most preferred embodiment key structure schematic diagram.
In figure: 1 leg；2 atmosphere protection chambeies；3 newels；4 anti-gas-leak pads；5 high temperature resistant bolts；6 metal base grinding wheels.
Specific embodiment
With reference to specification drawings and specific embodiments, this utility model is described further.
This utility model can achieve the sintering of single metal base grinding wheel, such as Fig. 1 a, Fig. 1 b, and emery wheel main body is disc, in
There is through hole centre.Sintering emery wheel requires that in emery wheel temperature is uniform, dense structure uniformly, the purpose of this device is to prevent metal from combining
While agent is oxidized it is ensured that during emery wheel sintering temperature is uniform, dense structure uniformly, thus obtaining mechanical property, installation
Performance and the good emery wheel of processing characteristics.
Referring to Fig. 2, Fig. 3, atmosphere protection chamber 2 bottom is provided with leg 1, and the through hole of metal base grinding wheel 6 is passed through newel 3
It is placed in atmosphere protection chamber 2, then anti-gas-leak pad 4 is installed between atmosphere protection chamber 2, connects atmosphere with high temperature resistant bolt 5
Protection chamber 2.Finally mounted sintering equipment is placed on burner hearth central authorities, by protective gas from air inlet from inflow, from aerofluxuss
Gas is discharged in hole, is heated after air drains.This device adopts modular design, and the height of sintered location can be according to tool
Body situation is adjusted.
Certainly, the foregoing is only the detailed description of an embodiment and the pattern that this utility model comprises, for illustration
And it is not all.The similar deformation made or replacement on the premise of without departing from this utility model principle and spirit, all should include
Among the protection category of this patent.
