Description
Technical field
The utility model is related to a kind of plane rolling tool, especially a kind of constant force plane rolling tool.
Background technology
Rolling process refers to that in the presence of rolling tool 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
Move etc. crystallography motion the big crystal boundary in small angle is 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 is one kind of chipless processing, and it can not only reach very high finish, and can improve quilt
Process mechanical performance --- case hardness, the fatigue behaviour of material, decay resistance of material etc. of part.The essence of rolling process
It is without sword instrument using high rigidity --- ball or roller, it is caused partial high pressure to surface to be machined.Due to instrument edge
Surface to be machined is rolled, and is formd the elastic-plastic deformation of surfacing, is made previous process stay the microcosmic hill in surface to be ground
