Embodiment
The present invention is further described with reference to the accompanying drawings and examples, and the content of embodiment is not as the guarantor to the present invention
Protect the limitation of scope.
The present invention relates to a kind of radium-shine processing method of the netted constitutional detail of metal material, it passes through metal injection moulding skill
Art and radium-shine process technology are combined to manufacture the netted constitutional detail of metal material.
As shown in figure 1, the radium-shine processing method of the netted constitutional detail of metal material of the present invention comprises the following steps：
First, metal material powder and binding agent are selected.
The netted constitutional detail of metal material is prepared by Metal Injection Molding, it is necessary to select suitable raw material
To prepare feeding.In the present invention, selected metal material powder is 316L powder of stainless steel and its particle diameter is 10-20 microns.
Selected binding agent is modeling based binder.Preferably, the modeling based binder is POM, PE, EVA, SA and PW mixture.And
And, wherein, the mass percent of each composition is：POM 75%-89%；PE 4%-10%；PW 3%-10%P；SA 2%-8%；EVA
1%-10%.Select this metal material powder and binding agent, it can be ensured that feeding has good mobility, stability and melting
Index, so that it is guaranteed that the performance of the netted constitutional detail of metal material.
Secondly, selected metal material powder and binding agent is utilized to prepare feeding.
In the present invention, feeding is specially that the metal material powder and the binding agent are placed in banbury 190
Mixing prepares the feeding in 2 hours at DEG C.Also, when preparing feeding, the metal material powder accounts for feeding gross weight
60-80%, the binding agent accounts for the 20-40% of feeding gross weight.It can guarantee that using the feeding of this preparation method and this proportioning
The netted constitutional detail of metal material of preparation has good mechanical performance and is convenient for radium-shine processing.
Certainly, after feeding is prepared, feeding performance can be detected.The feeding performance detection includes feeding
Mobility-detected and the detection of feeding melt index.In specific detection, feeding performance detection part can be prepared, passes through feeding performance
Detection piece carries out the combination property detection of feeding.The contents of the section is not the emphasis place of the present invention, therefore is not described in detail here.
Again, by feeding performance detection, if detecting that the mobility of feeding, stability, melt index etc. all meet
It is required that, then, it is possible to use the feeding injection moulding metal material green compact.
In the present invention, it is preferred to, in injection moulding, injection temperature is 190 DEG C, and mould temperature is 120 DEG C, and injection pressure is
80MPa, injection speed is 60cm3/ s, the dwell time is 1s, and dwell pressure is 30Mpa., can by this ejection forming method
Desired metal material green compact are met to prepare, it causes it to be easy to carry out radium-shine processing.
Then, network structure, formation are processed using radium-shine light beam is radium-shine on the metal material green compact after injection moulding
The green compact of the netted constitutional detail of metal material.
Because radium-shine light beam has high brightness, high directivity, high monochromaticity and high coherence's four characteristicses, therefore just give radium
Penetrate the characteristic processed and brought not available for some other processing methods.Simultaneously as it is contactless processing, to material without direct
Impact, therefore without mechanically deform；Worn and torn in radium-shine process without " cutter ", material is acted on without " cutting force "；Radium-shine processing
During, radium-shine light beam energy density is high, and process velocity is fast, and is partial operation, or shadow no to non-radium-shine irradiated site
Sound is minimum.Therefore, in the present invention, by using radium-shine processing, the breaking occurred in finishing impression processing, dimensional accuracy are solved small
The problem of.Meanwhile, by radium-shine processing, superfine aperture can be processed, aperture is less than 0.4mm, and such as aperture is 0.3mm net
Shape structure.It is to carry out radium-shine processing to metal material green compact to be additionally, since, therefore, is easy to the radium-shine of mesh in network structure to add
Work shapes.
Finally, degreasing sintered shaping is carried out to the green compact of the netted constitutional detail of the metal material, the metal material is made
Expect network structure part.
In the present invention, it is preferred to, the degreasing is specially catalysis degreasing 6 hours under 120 DEG C of skimming temp.Using
This degreasing method, can get rid of used binding agent during injection moulding, it is ensured that the performance of part.
It is highly preferred that the specific embodiment of the sintering is：With 4 DEG C/min programming rate by the temperature liter of sintering furnace
Temperature is to 600 DEG C and is incubated after 90min, and the temperature of sintering furnace is warming up into 1100 DEG C with 5.55 DEG C/min programming rate and is incubated
After 90min, then the temperature of sintering furnace is warming up to 1380 DEG C with 3.5 DEG C/min programming rate and 120min is incubated, finally will
The temperature of sintering furnace, which is down to after 1000 DEG C, turns off sintering furnace power supply, allow the netted constitutional detail of the metal material in sintering furnace from
It is cooled to ambient temperature and is drawn off.This sintering process, which is able to ensure that in the netted constitutional detail of the metal material, does not have sand
The problems such as eye, skewness.
With using metal injection moulding in the prior art compared with finishing impression processes the method being combined, metal material of the invention
Metal material mesh of the aperture less than 0.4mm of the mesh of network structure can be processed by expecting the radium-shine processing method of mesh-structured part
Shape constitutional detail, such as aperture of the mesh shown in Fig. 2 is the 0.3mm netted constitutional detail of metal material.In fig. 2, institute
The length for stating the mesh-structured part of metal material is that 25mm, width are that 20mm, the aperture of mesh are that 0.3mm, pitch of holes are 0.5
mm.And which solve occur in finishing impression processing breaking, the problem of dimensional accuracy is small.
The above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not to the present invention
Embodiment restriction.For those of ordinary skill in the field, it can also make on the basis of the above description
Other various forms of changes or variation.Here all embodiments can not be exhaustive.Every skill for belonging to the present invention
