Abstract
The present invention relates to a kind of bottle blowing machine Surface hardened layer production technology, the mold cavity surface of aluminum alloy mould is polished, aluminum alloy mould after polishing is put into the oxidation trough with electrolyte and carries out hard anodizing, the control mode of wherein oxidation current uses the DC current superimposed pulse electric current again that current density is 1.2 ~ 4.5A/dm2 for 0.5 ~ 3.5A/dm2 alternating current superimposed current density；Electrolyte uses mixed liquor of the concentration for organic acid that the inorganic acid and concentration of scope 17% ~ 19% are scope 4% ~ 6%, and weakly conducting film is smeared at the parting line at the die cavity edge of aluminum alloy mould, the mold cavity surface of aluminum alloy mould to completing oxidation is polished again, the present invention aoxidizes one layer of hardened layer by the mold cavity surface in aluminum alloy mould, so that mold cavity surface is more wear-resisting, corrosion-resistant, it is difficult for drop-off and hardened layer is firmly combined with mold cavity surface.
Description
Technical field
The present invention relates to beverage bottle processing equipment field, more particularly to a kind of bottle blowing machine Surface hardened layer production technology.
Background technology
Bottle blowing machine in the course of the work, with the mould that beverage bottle directly contacts be worn in complete machine part the most serious it
The surface of one, particularly mold cavity.During the injection of airflow, the surface of mold cavity easily produces abrasion, goes out
Existing pit, and the surface of mold cavity is in contact with the surface of beverage bottle, the pit after abrasion directly affects the quality of beverage bottle,
Therefore, the rub proofness of die cavity directly determines the quality of beverage bottle.
The content of the invention
It is an object of the present invention to provide a kind of bottle blowing machine Surface hardened layer production technology.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of surface of bottle blowing machine aluminum alloy mould
Hardening process, the mold cavity surface of aluminum alloy mould is polished, the aluminum alloy mould after polishing is put into electrolyte
Hard anodizing is carried out in oxidation trough, the control mode of wherein oxidation current uses current density as 0.5 ~ 3.5A/dm 2
Alternating current superimposed current density be 1.2 ~ 4.5A/dm 2 DC current superimposed pulse electric current again；Electrolyte uses
The mixed liquor for the organic acid that concentration is the inorganic acid of scope 17% ~ 19% and concentration is scope 4% ~ 6%, and in aluminium alloy mould
Weakly conducting film is smeared at the parting line at the die cavity edge of tool, is carried out again to completing the mold cavity surface of aluminum alloy mould of oxidation
Polishing.
Because above-mentioned technical proposal is used, the present invention has following advantages and effect compared with prior art：The present invention passes through
One layer of hardened layer is aoxidized in the mold cavity surface of aluminum alloy mould so that mold cavity surface is more wear-resisting, corrosion-resistant, and hardened layer
It is firmly combined with mold cavity surface, it is difficult for drop-off.
Brief description of the drawings
Accompanying drawing 1 is the schematic diagram of aluminum alloy mould.
Wherein：1st, aluminum alloy mould；2nd, die cavity；3rd, oxide layer.
Embodiment
Below in conjunction with the accompanying drawings and case study on implementation the invention will be further described：A kind of bottle blowing machine Surface hardened layer produces work
Skill, it includes：The mold cavity surface of aluminum alloy mould is polished, the aluminum alloy mould after polishing is put into electrolysis
Liquid, temperature range control carry out hard anodizing in -8 ~ -2 DEG C of low-temperature oxidation groove, wherein：The control of oxidation current
It for 0.5 ~ 3.5A/dm 2 alternating current superimposed current density is that 1.2 ~ 4.5A/dm's 2 is straight that mode, which uses current density,
Flow electric current superimposed pulse electric current again, the frequency of pulse current is 40-60 hertz, the scope of dutycycle is 20%-60%；Controlled with this
The speed of oxygenerating layer generation and the structure of oxide layer；It for 18% sulfuric acid and concentration is 5% 2 that electrolyte, which uses concentration,
Carboxyl acetic acid mixed liquor；And weakly conducting film is smeared at the parting line at the die cavity edge of aluminum alloy mould, to completing oxidation
The mold cavity surface of aluminum alloy mould is polished again.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that Spirit Essence is made, it should all be included within the scope of the present invention.
