Abstract
The utility model relates to a prefabricated structure of a magnesium alloy enclosure, which is characterized in that at least one per-forming impact forging step is performed by a figurate mould, softened magnesium alloy plate is forged and pressed into a prefabricated structure of enclosure, and parts, such as a fastening part, a stud bolt part, a rib part, a differential section, an art designing part, and the like, are disposed on a designed position. The processes such as final side scrap, finishing, and the like, are selectively performed on demand of products, so the acquired structure of the magnesium alloy enclosure has fine appearance, high size precision and excellent radiating property.
Description
[technical field]
The utility model relates to a kind of casing semi-finished product structure, refers to especially a kind ofly to utilize impact forging processing operation to produce to have accurate size, the prefabricated structure of magnesium alloy casing of thin portion's configuration and exquisite outward appearance.
[background technology]
Because the hand-held electric device of 3C such as mobile phone, PDA, mobile computer is stressed commodity demands such as light weight, intensity height, anti electromagnetic wave, the existing trend that plastic casing is changed into the light metal shell; Add, environmental consciousness comes back, and in European Union and Japan's recovery decree that legislation enforcement electronics and IT products are relevant in succession in recent years (for example: European Union's agreement global electronic products need reach 75 percent requirement of reclaiming material in 2006), the light metal of tool recovery property can be used to replace the optimal material of plastics as shell in the middle of becoming 3C Product.The material of common metal material is attached most importance to than plastics, but intensity is higher, therefore if use metal materials such as magnesium, magnesium, titanium, can develop the goods of light weight, high strength; Again and since magnesium alloy possess lightweight, thermal diffusivity good, can prevent electromagnetic interference, hardness and plasticity advantages of higher, in the application of each industry, emerge fast already.But magnesium alloy forged workpiece also has mouldability deficiency (for example the joint of shell must be made of the mode of screw with side direction locking), easily deformable, surface of the work also to produce problems such as forging defect.Obvious with regard to existing magnesium alloy (or magnesium alloy, magnesium magnesium alloy) forges processing procedure, it is to be overcome to still have some problems to have.
[utility model content]
In order to solve the above-mentioned deficiency of prior art, the utility model purpose is to provide a kind of mould of set shape.
For achieving the above object, the technical scheme that one of the utility model embodiment is provided is: the mould with set shape imposes at least one preformed impact forging step, softening magnesium alloy plate is forged into the prefabricated structure of the roughly external form of outer shell product, this prefabricated structure and be provided with at least as structural feature such as snapping portion, double-screw bolt portion, rib portion, segment difference section, art designing's lines at specified location is so that cooperate the requirement of goods (hand-held electric device) optionally to impose processing such as last side cut, finishing.According to this, can cooperate the product requirements selectivity to impose processing such as last side cut, finishing, in order to do can and then obtain outward appearance careful, have splendid dimensional accuracy, and the 3C magnesium alloy casing structure that possesses the good heat radiating characteristic.

[specific embodiment]
The basic structure of its integral prefabricated structure is shown in first figure, mould with set shape, as various hand-held electric devices: notebook computer, mobile phone, PDA ... Deng, impose at least one preformed impact forging step, softening magnesium alloy plate is forged into the prefabricated structure 10 of the roughly external form of outer shell product, this prefabricated structure 10 and be provided with at least as structural feature such as snapping portion 11, double-screw bolt portion 12, rib portion 13, segment difference section 14, art designing's lines 14 at specified location.
When implementing, impose at least one preformed impact forging, main moulding impact forging together at magnesium alloy plate again according to obtaining magnesium alloy plate earlier; Wherein, earlier the magnesium alloy base material is made into the magnesium alloy plate of en plaque, again the magnesium alloy plate is made with mode of heating and become softening solid, cooperate the mould of set shape to impose at least one preformed impact forging step simultaneously, softening magnesium alloy plate is forged into the magnesium alloy semi-finished product of the roughly external form of goods, when implementing, for guaranteeing the forging temperature moulding of magnesium alloy materials in regulation, the magnesium alloy plate is adapted at having the interior heating of resistance furnace of forced circulation air and automatic temperature-control most, temperature homogeneity in the stove is had relatively high expectations, forging in addition with mould also needs preheating, makes the flowability that increases metal in order to filling die cavity.
Earlier the magnesium alloy semi-finished product are annealed before carrying out main moulding impact forging step follow-up, then cooperate the mould of set shape that the magnesium alloy semi-finished product are imposed last main moulding impact forging step with processing temperature again a little less than the preformed step, in order to thin portion configurations such as the snapping portion that forms goods, segment difference section, left-hand thread portion, double-screw bolt position, rib positions, promptly constitute the prefabricated structure of aforesaid casing, and the prefabricated structure of the casing that allows forging finish obtains best hardness.According to this, can cooperate the product requirements selectivity to impose following process such as side cut, finishing at last again handles, so that finish the procedure for processing of all magnesium alloy casings, in order to do can and then obtain outward appearance careful, have splendid dimensional accuracy, and the 3C magnesium alloy casing structure that possesses the good heat radiating characteristic.Especially, the prefabricated structure of casing can be according to the goods form of required moulding, elder generation is via the temporary type impact forging of the first road preformed, again by the second road preformed impact forging, make its shell form predetermined form, and further after the finishing step again in conjunction with the colouring step, the colouring step then can be spraying method or anode processing mode.
