Abstract
The invention relates to a casting aluminium alloy spectacle fame with a surface capable of decoratively anodizing and a manufacturing method thereof. The aluminum alloy of the casting spectacle frame or earpieces contains 0.1-4.0% of silicon by weight, 0.05-8.0% of titanium by weight, and the balance of aluminum and trace impurities. In manufacture, pure aluminium pigs, aluminum-titanium alloy and silicon metal particles are added into a smelter hearth; the temperature and time are controlled in refining; alloy fusant is injected into a spectacle frame fitting mold at approximately liquidus temperature, so that a relative spectacle frame fitting is obtained after casting forming; the fitting goes through decorative anodization treatment after heat treatment, then the assembly is carried out, and the aluminium alloy spectacle frame is obtrained. The invention adopts reasonable contents of material elements, avoids the formation of bulky pinetree structure in the course of the melting to guarantee the uniformity of the aluminium alloy, has favorable appearance effect of oxidation, and can meet the requirement of decorative anodization on the surface. The material has high tensile strength and antifatigue and can meet the requirements of the production and the use the spectacle frame.
Description
Technical field: the manufacture method that the present invention relates to a kind of casting aluminium alloy spectacle fame.
Background technology: existing aluminium alloy spectacle fame generally adopts the mode of extrusion process to make, and complex process need be welded.In addition, picture frame and mirror pin all will carry out flexural deformation, different parts deflection difference, so there is aberration in the color relation of the surperficial anode oxide film of these different parts, influences quality.If adopt forging type to make aluminium alloy spectacle fame, have be shaped fast, shorten the production cycle, mirror holder do not have advantages such as solder joint.But casting method commonly used forms thick pine-tree structure easily in casting process, cause phenomenons such as aluminum alloy surface anodic oxidation difficulty or anode oxide film be of poor quality, make anodised rete very dark, do not have metallic luster, do not have ornamentally, influence the outward appearance class of product.
Summary of the invention: at the deficiencies in the prior art, it is reasonable to the invention provides a kind of technology, the manufacture method of the casting aluminium alloy spectacle fame of surface capable of decoratively anodizing.
The manufacture method of aluminium alloy spectacle fame of the present invention is to adopt following steps to carry out successively,
(a) add load weighted fine aluminium ingot in smelting furnace, temperature is controlled at 700-720 ℃, 20-30 minute;
(b) add load weighted aluminum titanium alloy and silicon metal grain, temperature is controlled at 700-720 ℃, 20-30 minute;
(c) feed the inert gas refining, temperature is controlled at 700-720 ℃, is no less than 3 minutes;
(d) add the refining agent refining again, temperature is controlled at 700-720 ℃, is no less than 30 minutes;
(e) near under the liquidus temperature alloy melt being injected spectacle frame accessory moulds such as picture frame, mirror pin, obtain corresponding spectacle frame accessory behind the casting;
(f) then above-mentioned accessory is incubated processing 1-12 hour down at 280-550 ℃, is cooled to room temperature;
(g) each accessory is carried out assembling connection after corresponding decoratively anodizing handles again, make aluminium alloy spectacle fame.
The present invention adopts in the process of smelting and pouring aluminium alloy near carrying out casting under the liquidus temperature, avoided thick arborescent structure structure to form, guarantee the homogeneity of aluminium alloy, made the better effects if of spectacle frame parts list surface anode oxidation, can satisfy the requirement of decorative surface.And, be directly used in casting after the aluminum alloy materials melting, the production efficiency height, quality is more guaranteed.
The aluminium that contains silicon, 0.05-8.0% titanium and the surplus of percentage by weight 0.1-4.0% in the general prepared aluminium alloy mirror holder.According to material requirements, can in above-mentioned steps (b), add load weighted zinc granule, and load weighted alumal, normally make the zinc that contains percentage by weight 0.01-4.0% in the mirror holder and the manganese of 0.01-5.0%.Because the difference of aluminum alloy materials composition, its liquidus temperature also can change, and the cast temperature of the alloy melt of step in the inventive method (e) is generally according to the difference of alloying component and difference.Equally, the accessory heat treatment temperature in the step (f) is according to the difference of alloying component and difference.
Further specify the present invention below in conjunction with drawings and Examples.
Description of drawings: accompanying drawing is the synoptic diagram of the prepared a kind of spectacle frame of the present invention.
Embodiment: as shown in the figure, aluminium alloy spectacle fame comprises picture frame 1 and mirror pin 2, and decoratively anodizing has been carried out on picture frame 1 and mirror pin 2 surfaces, and appearance is very attractive in appearance.
The manufacture method of present embodiment is to adopt following steps to carry out successively,
(a) add load weighted fine aluminium ingot in smelting furnace, temperature is controlled at 700-720 ℃, 20-30 minute;
(b) add load weighted alumal, aluminum titanium alloy, zinc granule and silicon metal grain, temperature is controlled at 700-720 ℃, 20 minutes;
(c) fed stable in properties gas refinements such as inert gas or nitrogen 3 minutes, temperature is controlled at 700-720 ℃;
(d) added the refining agent refining again 35 minutes, temperature is controlled at 700-720 ℃;
(e) near under the liquidus temperature, generally be 655-660 ℃, alloy melt injected the mould of spectacle frame accessories such as picture frame 1 and left and right mirror pin 2, obtain corresponding spectacle frame accessory behind the casting;
(f) then above-mentioned accessory is incubated processing 4 hours down at 300 ℃, is cooled to room temperature,, also can carry out corresponding machine work and replenish processing as needs;
(g) each accessory is carried out assembling connection after corresponding decoratively anodizing handles again, make aluminium alloy spectacle fame.
Contain the silicon of percentage by weight 0.5%, 2.0% titanium, 0.1% zinc, 0.1% manganese in aluminium alloy picture frame 1 that makes or the mirror pin 2, surplus is an aluminium, this aluminium alloy spectacle fame product tensile strength height, extensibility height, fatigue performance are good, and the decorative effect of oxidation processes is very attractive in appearance.
