Abstract
The invention relates to a process for processing a magnesium alloy shell. The process is characterized in that the process comprises a metal hot die punch forming process which comprises the following steps: 1. a special forming die is placed on an oil pressure type punching machine, and the die is heated up to a temperature of between 150 and 280 DEG C; 2. the magnesium alloy material is directly placed on the heated forming die; and 3. the punch forming is performed. The process facilitates realization of punch processing production of the magnesium alloy shell so as to improve product quality and production efficiency; moreover, the process also has the advantages of original conception, reasonable design, and big popularization value.
Description
Technical field
The present invention relates to a kind of technique for processing magnesium alloy case.
Technical background
Magnesium alloy plasticity at normal temperatures is very low, and its percentage elongation has only about 4~5%, and therefore embrittlement easily be difficult at room temperature carry out plastic working.Most of on the market at present magnesium alloy case all is to make with the production of high temperature fused state casting film molding mode with magnesium chips and magnesium ingot, because magnesium alloy is oxidized fully aborning, thereby causes magnesium alloy case all not have metallic luster and metal sense.
Summary of the invention
The purpose of this invention is to provide a kind of technique for processing magnesium alloy case, this technology helps realizing the punch process production of magnesium alloy case, thereby improves the quality and the production work efficiency of product.
Method of the present invention is achieved in that and comprises metal fever die stamping moulding process, and the process of described metal fever die stamping moulding process is as follows: (1) is positioned over moulding mould special on the hydraulic type punching apparatus, and makes mold heated to 150~280 ℃; (2) magnesium alloy materials (as the magnesium alloy of AZ series, AM series, AS series, AE series) is placed directly on the mould that has heated; (3) punch forming.
Advantage of the present invention is that technology is simple, and is easy and simple to handle, good product quality.
Description of drawings
Fig. 1 is the used hydraulic type punch press of technology of the present invention and the organigram of mould.
Fig. 2 is the job state schematic diagram of adhesive-bonded fabric roller brush.
The specific embodiment
Its preparation technology's of the present invention embodiment is as follows:
At first carry out metal fever die stamping moulding process, the process of described metal fever die stamping moulding process is as follows: (1) is positioned over moulding mould special on the hydraulic type punching apparatus, and makes mold heated to 150~280 ℃; (2) magnesium alloy materials is placed directly on the mould that has heated; (3) punch forming.Wherein punch forming operation is a critical process, and technical difficulty is higher, and dangerous end broke when its failure mode was drawing and forming.
The influence factor of this technology is as follows: briquetting pressure, shaping speed, equipment operating position, pressurization retention time, die clearance, angle, mould garden, mold temperature, material temperature etc., and also have interaction between each factor.Dangerous end broke when its failure mode was the hot-die punch forming.
In order to help controlling the temperature of mold heated, adopt the mold heated Temperature-controlled appliance to set the temperature of adjusting die test work.When the temperature of drift/stripper plate in 120~200 ℃ scope, the temperature of injection block/mould is in 150~280 ℃ scope, and punch press outer slide pressure is 35~45 ton hours, the drawing and forming effect is preferable.Wherein the organigram of drift (3), stripper plate (2), injection block (5), mould (4) and punch press outer slide (1) as shown in Figure 1.Because the thermal conductivity of magnesium alloy is good, magnesium alloy materials being placed directly on the mould that has heated in stamping forming blink, can finish the heating of magnesium alloy materials, make magnesium alloy materials be heated to 100~200 ℃.
After finishing metal fever die stamping moulding process, carry out the metal surface drawing process.The surface wire drawing is to form strain line by abrasive product at surface of the work, plays a kind of surface treatment means of decorative effect.Wire drawing is handled and can be made the metal surface obtain metallic luster as the non-specular surface, has very strong decorative effect as the silk satin face.Wire drawing is handled does not have unified classification and call.Usually be divided into raw silk rings and sleave according to the surface effect difference.Raw silk rings is called the hair line again, and sleave is called the snowflake line again.
As shown in Figure 2, adopt the method for adhesive-bonded fabric roller swishing sound silk to produce in actual applications.The adhesive-bonded fabric roller brush (6) of stamping forming workpiece to be machined (7) through being located at the high speed rotation on the production line forms wire drawing on the workpiece to be machined surface, workpiece to be machined transmits by conveyer belt (8), can adopt vibration of roller brush and roller brush not to vibrate dual mode during wire drawing, thereby cooperate different process velocities to produce the different strain line of length simultaneously.The vibration of adhesive-bonded fabric roller brush can produce the very discontinuous silking (sleave) of uniformity; Adhesive-bonded fabric roller brush does not vibrate, and can produce continuous silking (long filament or be raw silk rings).Strain line by adhesive-bonded fabric roller swishing sound silk does not have concavo-convex feel, but the visual sensory of strain line is obvious.
After finishing above-mentioned technology, carry out clear-coated technology then.Described clear-coated its process is as follows: workpiece to be machined is carried out de-oiling fat immersion treatment, and--------------the polishes spraying is--at--polishing--finished product packing of oven dry below 75 ℃ in the static cleaning to wipe stain oil in oven dry below 130 ℃ in the priming paint spraying in the static cleaning to wipe stain oil.
Before carrying out clear-coated technology, to check at first whether the magnesium alloy plate surface exists physical imperfection, as point-like pit or salient point, cut, scratch etc.
Above-mentioned de-oiling fat immersion treatment operation adopts ultrasonic wave acetone to clean, and the time is 5-10 minute.
The above-mentioned priming paint spraying process of stating adopts the material of nylon priming paint (the great lacquer of China, Foochow China bright chemical industry Industrial Co., Ltd.) as spraying.
Because the polishes that adopts in the polishes spraying process (the great lacquer of China, Foochow China bright chemical industry Industrial Co., Ltd.) contain in the nano antibacterial agent (water white transparency nano titanium oxide Ag ion exchange body) of certain deal and anion material (tourmaline: a kind of have spontaneously intensify electrode, with the mineral of piezoelectricity and pyroelectricity, can be emitting far-infrared, chemical formula: XR3A16B3O27 X is sodium, K, Ca, R is Mg, Fe, Mn, Li and Al etc.), therefore make magnesium alloy case have anti-fingerprint, antibiotic, anion, characteristic such as infrared.
