Selective laser fusing shapes technical characterstic and includes: 1) this technology can realize precision component and personalization, small lot and
The manufacture of customization parts；2) compared with traditional method, this technology only need to change cad model, just can obtain part original shape so that
The difficulty of forming process is unrelated with the complexity of physical entity shape to be formed；3) laser spot diameter is about 0.1mm, should
Technology forming accuracy is high, and shaping surface precision is less than 0.1mm；4) additionally, use selective laser smelting technology the most closely to become
Shape part, shortens the production cycle and saves raw material.
In the fusion process of selective laser, during paving powder, the mobility of powder directly affects paving opaque amount.Powder diameter is less
Time, mobility is poor, and paving powder is in uneven thickness, thus causes difference between laser fusion powder area, meanwhile, and temperature field and stress
Field distribution is uneven, the defect such as profiled member may crack, buckling deformation.Metal dust can there be is pressure during scraper paving powder
Implementation use, generates static electricity by the rubbing action, and under electrostatic interaction, metal dust is reunited.Correlational study shows by preheated metallic powder
Metal dust mobility can be effectively improved, improve tissue topography and eliminate internal stress.Existing powder preheating device mostly uses
To the preheating of whole powder feeding cylinder, to the preheating of whole moulding cylinder and the preheating of whole powder feeding cylinder, these method consumed energies are more, and preheating
Inefficient；Heating location is unreasonable so that metal dust is easily bonded together, and is unfavorable for forming parts.
Summary of the invention
The purpose of this utility model is to provide a kind of precinct laser fusion Graphene coating blade local preheating device,
It can effectively solve the problem that problem present in background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of precinct laser fusion Graphene is coated with

Compared with prior art, the beneficial effects of the utility model are: this precinct laser fusion Graphene coating blade
Local preheating's device is by preheating metal dust, and flow of powder ability increases, and in forming cavity, thermo parameters method is equal
Homogenizing, forming part performance rises；The advantage of local preheating, prevents extraneous bulk temperature too high, to molded workpiece and zero
Part produces heat effect, affects its operating accuracy, because of substrate and the forming cavity side-wall material coefficient of expansion when preventing substrate entirety from heating
The inconsistent extrusion abrasion caused or loosely leak powder；Along with metal dust temperature raising metal dust to laser absorption coefficient also
Increased, improve production efficiency；There is electrostatic function；Utilize unilateral Graphene coating blade powder feeding cylinder to be protected simultaneously
Temperature and moulding cylinder preheating, effectively simplify the internal structure of an organization, and reduces heat input simultaneously, reduces the load that amount of residual heat is discharged by equipment, significantly
Extend its service life.
