Description
Technical field
The present invention relates to a kind of plane rolling tool, the measurable flexible electric spark deposition rolling depression cutter of especially a kind of rolling power
Tool.
Background technology
Rolling process refers under the action of rolling tool, and forced plasticity deforming occurs for external force inducing metal material surface, passes through
The nonequilibrium defects such as dislocation, fault of Plastic Flow activation crystals of nearly skin-material, by dislocation multiplication, twin, sliding
The crystallography movement such as move and the big crystal boundary in small angle be gradually cut into the small crystal boundary in big angle, realize surface big crystal grain be divided be refined as it is ultra-fine
It is brilliant or nanocrystalline.Rolling and processing be chipless processing one kind, it can not only reach very high finish, and can be improved by
The corrosion resistance etc. of the mechanical performance of processing part --- case hardness, the fatigue behaviour of material, material.The essence of rolling process
It is using high rigidity without sword tool --- ball or idler wheel make it cause partial high pressure to workpiece to be machined surface.Due to work
Tool is rolled along surface to be machined, forms the elastic-plastic deformation of surfacing, previous process is made to stay the microcosmic hill in surface
It is rolled, and the surface layer grain of material is made to become smaller, ultimately become nanocrystalline.
Rolling tool is connect by the main shaft of the lathes such as handle of a knife and milling machine, and band dynamic cutter head rotates, to on dynamic cutter head
Idler wheel realizes rolling and processing in workpiece surface rolling.Rolling tool is generally divided into two kinds of rigidity and elasticity.For rigid structure
Rolling tool, be suitable only for rolling coarse part, traditional stitching is inelastic, and processing is rigid, and easily makes work
Part surface generates the defects of " point ", " peeling ".When rigidity rolling, process system poor rigidity will cause the fluctuation of rolling power, make
Surface quality is uneven.When the material of the rolling power of idler wheel and rolling part hooks very much, good rolling effect could be obtained.Cause
This selects flexible rolling tools, flexible rolling tools that can rise in the rolling process in the high rolling and processing of surface quality requirements
To the effect of buffering, idler wheel can be made to keep identical rolling quantity, surface of test piece deflection is consistent, therefore can get uniform finishing
Rolling surface, but the disadvantage is that with lower amendment form error due to being mounted with elastic element in structure, can keep away
The huge fluctuation of rolling power can also suitably mitigate rolling tools to a certain extent caused by exempting from lathe vibrations, material unevenness
The impact being subject in process.But if rolling tool only has spring, rolling power is difficult to control, and rolling power is excessive, part
Surface local stress increases, and is easy to form rupture, delamination, reduces surface quality instead.Rolling tool rolling power is too small, cannot
So that the wave crest on workpiece to be processed surface is subdued, ideal roughness is not achieved.
Electric spark deposition is the technique that the high density energy directly using electric energy carries out deposition processes to metallic surface.It
It is the energy for directly utilizing spark discharge, electrode material is transferred to working surface, constitutes the deposition method of sedimentary.Electrode material
Material generates metallurgical binding with workpiece material and forms sedimentary.Due to forming the surface deposits of the alloying containing electrode material, make
Physical property, chemical property and the mechanical property of workpiece surface are improved, and the microstructure and mechanical property of its center portion does not occur
Variation.But the deposit thickness of traditional electric spark deposition is small, sedimentation time is long, surface roughness is low, so there is many defects.
And after material surface carries out rolling and processing, the coarse-grain on surface is refined into nanocrystalline, and there are a large amount of crystal boundary, three in nanocrystal
Crystal boundary and nonequilibrium defect are pitched, it can be as the channel of atoms permeating.The more conventional coarse-grain of atom has bigger in nanocrystal
Activity, the atom mobility on a large amount of crystal boundaries is very big, and atom is easily separated from lattice constraint, is more easy to spread.Research shows that atom exists
The nanocrystalline middle more conventional coarse-grain of diffusion is easy, and is mainly manifested in diffusion coefficient raising, diffusion activation energy reduces.
