The utility model discloses in, because the good ventilation effect of box body self, the processing that consequently need not to come out of the stove has improved work efficiency, has reduced intensity of labour. Furthermore, the utility model discloses be provided with the support hem, because the holding surface influences normal use less than leading to whole slope when having avoided a plurality of box body stromatolites.
Description
Technical field
This utility model is related to neodymium iron boron and produces sintering art, more specifically, it relates to a kind of sintered NdFeB opens wide
Formula sinters magazine.
Background technology
It is known that sintering rate of cooling has a major impact to sintered NdFeB magnetic property, as splendid attire blank product
Magazine, its air permeability, heat conductivity play decisive role to product cooling speed.Meanwhile, sintered NdFeB is to anti-oxidation
Require high, neodymium iron boron is suppressed, after pressing under magnetic field, had certain density through powder, but its consistency also only reach 50~
60%, it is actually existed with porous material form, and therefore easily adsorbed gas needs tightly to be prevented in whole process
Shield, often selects the graphite magazine of good airproof performance, thus creates and cannot take into account rate of cooling and sealing simultaneously in therefore producing
The contradiction of property, for this reason, manufacturer is after the completion of sintering densification, product is taken out from sintering furnace, then again puts
Carry out Ageing Treatment in unlimited magazine, the method effect is good, but there is the deficiency that workload is big, work efficiency is low.
Content of the invention
The technical problems to be solved in the utility model is the above-mentioned deficiency for prior art, provides a kind of sintered NdFeB
Open type sinters magazine, it is possible to increase ventilation, cooling effect in stove.
The technical solution adopted in the utility model is such:A kind of sintered NdFeB open type sinters magazine, its feature
It is, this magazine includes:
Box body, this box body is used for loading the container of sintering blank, and box body is interior empty square or cylinder, spacious above it
Mouth design;
Sealing flanging, this sealing flanging is fixed on box portion outside, is the extension of box body, positioned at apart from box body bottom 1/3 to
At 1/2 height;
Support flanging, be respectively arranged on outside bottom and uncovered portion, for providing support force during box body lamination;And
Through hole, this through hole has multiple, and it, above sealing flanging, and is distributed in box side wall, for cooling procedure
Ventilation.
Further, described sealing flanging width is 15~25mm, and described support flanging width is 5~10mm, described logical
Bore dia is 10-20mm.
A kind of sintered NdFeB open type sinters the using method of magazine, is realized by following steps:
Step 1:Mounted box, sintered NdFeB blank is attached in the magazine described in claim 1;
Step 2:Sealing, covers the uncovered portion of magazine using tinfoil, and tightens so as to be integrally formed at sealing flanging
Whole sealing;
Step 3:Unlimitedization is processed, and the magazine of sealing is gone in vacuum sintering furnace, heats under vacuo, so that tinfoil is melted
Change, so that magazine is opened wide in fact, through hole and ft connection on magazine.
Step 4:Sintering, timeliness, product sinters in vacuum sintering furnace, timeliness, and insulation is filled with nitrogen or inertia after terminating
The direct quenching of gas.
When the temperature in vacuum sintering furnace is 200~320 DEG C, tinfoil melts.
This utility model compared with prior art, has following technique effect:
1st, this utility model, by carrying out via design at magazine edge, improves ventilation, cooling effect in stove, improves
Properties of product.
2nd, a kind of sintered NdFeB open type sintering magazine of the present utility model is provided with support flanging, is respectively arranged on bottom
Outside portion and uncovered portion, for providing support force during box body lamination, it is to avoid because support force deficiency is led during multiple box body lamination
Cause integral inclined and affect normal use.
3rd, a kind of sintered NdFeB open type of the present utility model sinters magazine, due to itself good ventilation effect,
Therefore need not come out of the stove process, improve work efficiency, reduce labor intensity.Meanwhile, because need not come out of the stove, therefore reduce cold
But temperature requirement, reduces energy consumption.
4th, a kind of sintered NdFeB open type of the present utility model sinters magazine, make use of that tinfoil is salable and high temperature under
The feature of fusing, solves sealing and the ventilation sex chromosome mosaicism of magazine simultaneously, had both avoided in product loading furnace process because of sealing
Problem that is bad and being exposed to the oxidation leading in oxygen, hydraulic performance decline for a long time;Improve sealing magazine cold in high temperature again
But the bad problem of process air permeability, effect is good.
Brief description
Fig. 1 is the structural representation that a kind of sintered NdFeB open type of the present utility model sinters magazine.
Fig. 2 is the top view that a kind of sintered NdFeB open type of the present utility model sinters magazine.
In figure:1- box body, 2- seals flanging, and 3- supports flanging, 4- through hole.
Specific embodiment
Specific embodiment in below in conjunction with the accompanying drawings is described further to this utility model.
Refering to shown in Fig. 1-2, a kind of sintered NdFeB open type sintering magazine of the present utility model is it is characterised in that be somebody's turn to do
Magazine includes:Box body 1, sealing flanging 2, support flanging 3 and through hole 4.Box body 1 is used for loading the container of sintering blank, box body 1
For interior empty square or cylinder, open design above it;Sealing flanging 2 is fixed on outside box body 1, is the extension of box body 1,
It is located at the height of box body 1 bottom 1/3 to 1/2, described sealing flanging 2 width is 15~25mm;Flanging 3 is supported to be respectively arranged on
Outside bottom and uncovered portion, for providing support force during box body 1 lamination;Through hole 4 have multiple, its located at sealing flanging 2 above, and
And it is distributed in box body 1 side wall, for cooling procedure ventilation, improve cooling capacity.Designed by carrying out through hole 4 at box body 1 edge,
Improve ventilation, cooling effect in stove, improve properties of product.
This utility model is designed by carrying out through hole 4 at box body 1 edge, improves ventilation, cooling effect in stove, and by
In itself good ventilation effect, process of need not coming out of the stove, improve work efficiency, reduce labor intensity;Meanwhile, because need not
Come out of the stove, therefore reduce chilling temperature requirement, reduce energy consumption.This utility model is provided with support flanging, is respectively arranged on bottom
Outside uncovered portion, for providing support force during box body lamination, it is to avoid because support force deficiency leads to during multiple box body lamination
Integral inclined and affect normal use.Additionally, magazine of the present utility model, also use that tinfoil is salable and high temperature under fusing
Feature, solves the sealing of open type magazine and the ventilation sex chromosome mosaicism of sealing magazine simultaneously, and effect is good.
Above-described is only preferred implementation of the present utility model it should be pointed out that coming for those skilled in the art
Say, on the premise of without departing from this utility model structure, some deformation can also be made and improve, these are all without this reality of impact
Effect and practical applicability with new enforcement.
