S500, described workpiece semi-finished product being carried out Ageing Treatment, obtain workpiece after completing, the temperature of described Ageing Treatment is
170 DEG C～185 DEG C, the time of described Ageing Treatment is 7h～8h, after Ageing Treatment, natural cooling.
By F state aluminium is carried out Ageing Treatment, reach to improve the purpose of aluminium hardness, it is not necessary to through solution heat treatment
Operation, compares tradition forging and stamping and processes technique, can greatly reduce the input of people's force-summing device, reduce operation and the complexity of operation,
Also reduce production cost simultaneously.
Before step S300, also include cleaning step S200: preparation aluminum cleaning agent solution, aluminium is immersed in aluminum cleaning agent
In solution, take out after carrying out ultrasonic waves for cleaning 1min～10min, then clean with clear water.
The dominant mechanism of ultrasonic waves for cleaning is that small complex, under the effect of ultrasound wave, shakes present in chemical
Moving, grow and rupture suddenly, in the moment of bubbles burst, may produce up to the pressure of thousands of atmospheric pressure, its impulsive force be enough to
Dirt is made to crush, produced localized hyperthermia, high pressure, help speed up the dissolving of dirt, reach the purpose cleaned；Ultrasound wave adds
Within the temperature range of warm wash can be heated to 78 DEG C-98 DEG C, it is preferred that 90 DEG C can be heated to ultrasound wave and be carried out.
In more detail, aluminum cleaning agent solution includes that mass percent is the water of 110:6.0:0.5, Wax removal water, degreasing powder,
Wax removal water has removes emulsifying capacity and the cleaning force to greasy dirt to waxiness dirt, both economically and environmentally beneficial, nontoxic, degreasing powder
Polyoxyethylene Lauryl Ether, defat is rapid, can the most thoroughly remove the oils and fats on workpiece, and the corrosion-free and variable color to surface of the work after cleaning
Phenomenon.
Concrete, F state aluminium can be immersed equipped with carrying out ultrasonic waves for cleaning, ultrasound wave in the washing trough of this aluminum cleaning agent solution
The time cleaned may be configured as 5min；During cleaning, can be replaced the aluminum cleaning agent in washing trough, replacement frequency is
