The method has short manufacturing process, low energy consumption, short treatment time and low production cost in mass production; and the appearance with the sanded surface and hairline effects can be obtained.
Description
[technical field]
The invention relates to a kind of outward appearance processing method, particularly have the processing method of sand face and hair appearance relevant for a kind of magnesium alloy.
[background technology]
In recent years, for the environment of preserving our planet, people begin to have the trend of positive use magnesium alloy, and magnesium alloy has easy regeneration in practical metal, the in light weight and good characteristics of thermal diffusivity.
As in electronics and field of household appliances, be the center with the mechanism of mobile computer or mobile phone, there is the plastic material of using always from people to be transferred to the trend of the superior magnesium alloy of recovery property.And the most of practical casting die of the member of magnesium alloy, the semisolid ejection formation gives moulding.This casting be with at a high speed, high pressure injects the magnesium alloy of fusion or semi-molten state in the mould and gives moulding, with size accurate or productivity superior be feature.General appearance is handled relevant magnesium alloy component, and is similar to iron and steel or aluminium alloy situation, with spraying again after the surface treatment.But magnesium alloy belongs to and has the activity and the easy metal of corrosion in the practical metal, carries out surface treatment to form the outward appearance of exquisiteness and even metal sensation extremely important so reach as iron and steel or aluminum alloy surface.
For antirust, generally form rust-preventing film on the surface of metal forming product such as magnesium alloy molded product, simultaneously for attractive in appearance, also spray paint film.Existing processing procedure is long, takes time and effort, and the surface of the work paint film sense that obtains is pure, and product and the plastics part that sprays paint gives client's sensation consistent, can't embody the outward appearance of metal and feel.
[summary of the invention]
In view of this, the invention provides a kind of outward appearance processing method, this method processing procedure is short, and energy consumption is low, and the processing time is short, and production cost is low during volume production, and can obtain the appearance of tool sand face and hair effect.
According to purpose of the present invention, a kind of outward appearance processing method is proposed, comprise that step is as follows:
Produce a shaping workpiece;
Shaping workpiece is changed into processing;
Adopt finish to handle the appearance of shaping workpiece;
Printing ink with the figure of printing specific meanings on the surface of the work;
Workpiece after the printing is carried out blasting treatment obtain sand face effect;
Handle the glossiness of magnesium metal works by protecting light.
Compared to prior art, outward appearance processing method of the present invention can obtain the appearance of tool sand face and hair effect, and processing procedure is short, and energy consumption is low, the yield height, and the processing time is short, and production cost is low during volume production.
For purpose of the present invention, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:
[description of drawings]
Fig. 1 illustrates the flow chart of steps of outward appearance processing method of the present invention.
[specific embodiment]
As shown in Figure 1, outward appearance processing method of the present invention in a preferred embodiment, comprises that step is as follows:
Step 100: produce a shaping workpiece, in present embodiment, the mode that adopts semisolid to penetrate comes shaping workpiece (in addition, in other embodiment, also can adopt modes such as die casting to come shaping workpiece), it is to continue to shear and the quick cooled semi-solid magnesium alloy of metering ejaculation with a screw rod that above-mentioned semisolid penetrates, in this process, its mould keeps in temperature 240-270 degree, the moulding after mold temperature 220-240 degree, the material feeding (being that material feeding is to the die sinking time) 5-15s cool time, molding mass pipe temperature 590-610 degree, firing rate 1-3m/s, penetrates and press 80-120kgf/cm
2Above-mentioned ejaculation is finished, can obtain the workpiece of moulding after the cooling, preferably, thin portion's machinery (CNC) processing such as boring, moulding trip of shaping column on the surface of the work are carried out in the die-cut processing that the workpiece of above-mentioned moulding is cut away charging aperture, discharging opening and some burr on the shaping workpiece to the workpiece after the die-cut processing;
Step 200: the workpiece after the above-mentioned processing is changed into processing, the processing concrete steps that change into herein comprise: will wash after the degreasing of magnesium alloy sample surfaces, and then adopt organic acid that it is carried out activation processing, this organic acid is selected from acetic acid, oxalic acid, adjust with the alkalescence table again after the technical pure washing and show to transfer, promptly change into processing after the technical pure washing once more, described magnesium alloy sample is put into prepared chemical solution (chemical solution composition: calcium dihydrogen phosphate 10～30g/L; Phosphoric acid 2～10ml/L; Metavanadate 0.5～1.5g/L; Nitrate 5～15g/L) reacted 1 minute down at 45 ℃, and technical pure washing back is being toasted 20 minutes with its oven dry through 120 ℃ then; Through above-mentioned processing gained rete be light grey, and its impedance is less than 1.0 ohm, and this rete can not have obvious the corrosion by neutral salt spray test in 48 hours, reaches more than 9 grades;
Step 300: the above-mentioned workpiece that changes into after the processing is carried out finish handle appearance, in present embodiment, utilizing wire drawing machine that workpiece is carried out automatic wire drawing handles, the workpiece wire drawing of on wire drawing machine, polishing, thereby reduced the appearance of magnesium alloy workpiece, the reduction scope of surface of the work is handled the processing procedures such as grinding and polishing, benefit soil and polishing that replaced in the former processing procedure according to demand at 0.05mm-0.1mm by this wire drawing, obtains the outward appearance of desirable metal-like and the effect of hair line;
Step 400: the printing ink of the figure of specific meanings in specific position printing of the workpiece after finish is handled, printing ink can adopt UV type photocuring or anti-sandblast printing ink, color can be painted according to customer demand, the figure of this specific meanings can be literal, sign, pattern wherein among one or many persons' combination, figure can be at a place, also can be dispersed in many places simultaneously, the color of figure is unrestricted;
Step 500: the workpiece after the printing is carried out blasting treatment, be preferably: utilize sand-blasting machine to adopt 180～400# white fused alumina, under 150～500MPa, carry out, thereby obtain the metal appearance of sand face effect, can adopt dry blasting and wet abrasive blasting according to sand face effect needs simultaneously;
Step 600: protect light and handle, purpose is magnesium chips after the above-mentioned wire drawing of removal and the glossiness that obtains ideal effect magnesium metal, be preferably: to processed workpiece through cleaning by degreasing and Passivation Treatment, the Passivation Treatment surface needs to keep the magnesium alloy effect, surface of the work can be coated with last layer coating during guarantor's light was handled, make it more corrosion-resistant, anti-neutral salt spray reaches 96h, adopting one face to be coated with gets final product, primary coat before replacing in the technology and face such as are coated with at the multiple tracks processing procedure, coating process be transparent, cloudy surface or band color one of them, coating can have the coating of antibacterial functions as required.
Outward appearance processing method of the present invention can obtain the outward appearance of the sand face effect that has the figure of specific meanings and have hair line, and this method processing procedure is short, and energy consumption is low, and production cost is low during volume production.
