Description
Technical field
The invention belongs to aluminium alloy production technical field, and in particular to 7003 aluminum alloy production process of phone housing.
Background technology
Now most phone housing is using plastic production, and high-end handsets shell has part to be closed using 6063 or 6061 aluminium
Gold makes, and no matter plastic casing can not be compared with aluminum alloy casing from texture or effect.But outside 6XXX aluminium alloys
Shell is yielding because strength problem is easy to break.And anode is due to grain structure after using 7003 aluminium alloy plates directly extruded processing
The reason for, surface effect is bad after causing anode.
The content of the invention
In view of the shortcomings of the prior art, work is produced with 7003 aluminium alloys it is an object of the invention to provide a kind of phone housing
Skill, surface quality requirements after anodic oxidation can be met, the intensity deficiency that can solve the problems, such as 6 series alloys shells again.
To use following technical scheme up to this purpose, the present invention：
A kind of 7003 aluminum alloy production process of phone housing, comprise the following steps：
（1）According to the component founding aluminium ingot of following ratio of weight and number：Si<0.30、Mg 0.5-1.0、Fe <0.35、Cu<
0.2、Mn<0.3、Cr<0.2、Zn 5.0-6.5、Ti<0.2；
（2）Homogenization Treatments are carried out to aluminium ingot；
（3）Aluminium ingot is heated to 390 ~ 410 DEG C；
（4）Extruded using extruder；
（5）Extruded product is cooled down；
（6）Sawing is carried out after cooling；
（7）Product after sawing is carried out to wait channel extruding.
Further improve above-mentioned technical proposal, the step（3）It is middle that aluminium ingot is heated to 400 DEG C.
Further, the discharging speed of the extruder is 7 ~ 10M/Min.
Further, the step（5）In away from 700 ~ 900mm of extruder limber wall set sparge pipe to extruded product
Water-spraying control is carried out, sparge pipe is vertical setting relative to product from the extrusion direction of extruder.By in this way, can be real
Existing product is extruding the quick cooling of port, and cost is relatively low.
Further, the step（6）Sawing is carried out using automatic sawing machine, automatic sawing machine is provided with fixed plate, fixed plate
By screw connection holding pad, excellent power glue is installed between holding pad and fixed plate additional.By in this way, reducing to material linearity
And the dependence of sectional dimension, it is ensured that the linearity of product, perpendicularity after sawing, while the number of each sawing is improved to greatest extent
Amount, lift the production capacity of unit interval.
Beneficial effect：7003 aluminum alloy production process of phone housing provided by the invention, pass through formula and processing technology
Adjustment can meet surface quality requirements after anodic oxidation, can solve again 6 series alloys shells intensity deficiency ask
Topic；The intensity of existing 6 series alloys is：Tensile strength 260MPA, yield strength 240MPA, ductility 8-12%；And this hair
The intensity of bright 7003 alloy is：Tensile strength 400MPA, yield strength 340MPA, ductility 9-12%.
