Description
Technical field
The invention belongs to aluminium alloy production technical field, be specifically related to phone housing 7003 aluminum alloy production process.
Background technology
The most most phone housing is employing plastic production, and high-end handsets shell has part to use 6063 or 6061 aluminum to close
Gold makes, and no matter cabinet all cannot be compared with aluminum alloy casing from texture or effect.But outside 6XXX aluminium alloy
Shell is easy to break due to strength problem, yielding.And anode is due to grain structure after using 7003 aluminium alloy plate processing of directly extruding
Reason, cause anode rear surface effect bad.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of phone housing and produce work with 7003 aluminium alloys
Skill, can meet anodic oxidation rear surface prescription, can solve again the problem that the intensity of 6 series alloys shells is not enough.
For reaching this purpose, the present invention by the following technical solutions:
A kind of phone housing 7003 aluminum alloy production process, comprise the 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) aluminium ingot is carried out Homogenization Treatments；
(3) aluminium ingot is heated to 390 ~ 410 DEG C；
(4) extruder is used to extrude；
(5) extruded product is cooled down；
(6) sawing is carried out after cooling；
(7) carry out product after sawing waiting channel extruding.
Improve technique scheme further, aluminium ingot is heated to 400 DEG C by described step (3).
Further, the discharging speed of described extruder is 7 ~ 10M/Min.
Further, described step (5) is arranging sparge pipe to extruded product at extruder limber wall 700 ~ 900mm
Carrying out water-spraying control, sparge pipe is vertical setting from the extrusion direction of extruder relative to product.By so arranging, it is possible to real
Existing product is in the quick cooling of extrusion port, and cost is relatively low.
Further, described step (6) uses automatic sawing machine to carry out sawing, and automatic sawing machine is provided with fixed plate, fixed plate
Connect holding pad by screw, between holding pad and fixed plate, install excellent power glue additional.By so arranging, reduce material linearity
And the dependence of sectional dimension, it is ensured that the linearity of product, perpendicularity after sawing, improve the number of each sawing simultaneously to greatest extent
Amount, promotes the production capacity of unit interval.
Beneficial effect: phone housing 7003 aluminum alloy production process that the present invention provides, by formula and processing technique
Adjustment can meet anodic oxidation rear surface prescription, not enough the asking of intensity of 6 series alloys shells can be solved again
Topic；The intensity of existing 6 series alloys is: tensile strength 260MPA, yield strength 240MPA, ductility 8-12%；And this
The intensity of bright 7003 alloys is: tensile strength 400MPA, yield strength 340MPA, ductility 9-12%.
