Description
Technical field
The present invention relates to a kind of antidote of magnesium alloy thin plate casting residual deformation, category magnesium alloy plate casting processing
The technical field of molding.
Background technology
Magnesium alloy thin plate casting is widely used in electronic product as shell construction parts, such as in notebook electricity
Apply in brain, panel computer, digital camera, digital code camera, light-emitting diode display, mobile phone parts.
In molding, magnesium alloy thin plate casting solidification with cooling during, due to temperature and the cooling at each position
Speed is different, and foundry goods is different in the amount of contraction of same period, and each portion of foundry goods is the entirety being connected with each other, so as to cause foundry goods
Inside conditions each other and produces stress；When the foundry goods demoulding is cooled to room temperature, as linear shrinkage is obstructed generation thermal stress, foundry goods is made
Residual stress has been internally formed, when residual stress exceedes the yield strength of material, i.e., residual deformation can have been produced；Residual deformation meeting
Make magnesium alloy thin plate casting change original design size, lose original precision, also affect the attractive in appearance of product, especially criticizing
During amount production, the foundry goods that there is residual deformation can form waste product in machining.
At present, the residual deformation of magnesium alloy thin plate casting is mostly using manual correction, high labor intensive, production efficiency
It is low, and the bad grasp of dynamics is corrected, easily cause foundry goods and scrap；Also what is had is corrected using machinery, and foundry goods is put into heating
In mould, apply reversible deformation to foundry goods by mould to eliminate residual deformation, this method can only correct four edges deformation, to curved
Bent deformation, wave transformation, torsional deformation rectification effect it is not good, and low production efficiency；Become using manual and machinery correction remnants
Shape, simply enforceable temporary transient elimination residual deformation, cast-internal still suffer from residual stress, place a period of time in foundry goods, or
In being the follow-up course of processing, residual deformation gradually can rebound.
The content of the invention
