Description
Technical field
The present invention relates to a kind of heat treatment method of module heat radiator processing, particularly relate to the strain-aging processing method in a kind of large power supply aluminium alloy module heat radiator.
Background technology
How the large power supply module heat radiator is by digital control processing, and manufacturing procedures such as for example milling, boring, tapping realize dimensional accuracy control purpose.Present Ai-Mg-Si is that alloy profile passes through the extruding press quenching more, and timeliness heat treatment step subsequently obtains conventional T5 or T6 state.Because of the material through this processing is difficult to obtain higher intensity and hardness has reduced mach precision of radiator and surface smoothness.
Summary of the invention:
Main purpose of the present invention is to overcome above deficiency and a kind of strain-aging processing method that is used for large power supply aluminium alloy module heat radiator is provided.
The technical solution adopted for the present invention to solve the technical problems is: it comprises aluminium alloy extruded round ingot casting, homogenising heat treatment, heating furnace, extruding, quenching, finishing, sawing, artificial aging processing and pressing, it is characterized in that:
1.. the aluminium alloy extruded round ingot casting of strict check;
2.. conventional homogenising heat treatment;
3. heating furnace heats before entering extruding:
Its heating-up temperature is 460-500 ℃, and extrudate goes out die temperature greater than 510 ℃ → employing air-blast quenching;
4.. the aligning finishing;
5.. sawing, sorting, collection dress;
6.. pressing: because of the monomer accumulation of heat substrate both sides of extrusion molding have the slot that can peg graft mutually each other enhancement mode module heat radiator that the back constituted or the monomer fin that has hollow lattice structure and the whole accumulation of heat substrate inserting press combined type module radiator that the back constituted of pegging graft of pegging graft, pass through forcing press, and load action, the compression strain value takes place in the pressing process reach 5%;
7.. strain-aging is handled: above-mentioned module heat radiator is carried out strain-aging handle, its institution of prescription is 5% compression strain, 180 ℃ of heating-up temperatures, temperature retention time 8-12 hour;
8.. the digital control processing of module heat radiator finished product.
Advantage and good effect that the present invention has are: the present invention is intended to " strain-aging " technology notion and method, be effectively applied to module heat radiator manufacture field by " pressing " mode structure, module heat dissipating modulator material after strain-aging is handled can reach the T10 state, its mechanical performance and hardness number obviously promote than the T5 or the T6 state of routine, improved " machinability " of product, can realize high-speed milling, boring and tapping in the CNC operation, and deep processing effect and product surface fineness can improve more than 20%.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
The specific embodiment
For further understanding summary of the invention characteristics of the present invention and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1.
As shown in Figure 1: it comprises aluminium alloy extruded round ingot casting, homogenising heat treatment, heating furnace, extruding, quenching, finishing, sawing, artificial aging processing and pressing the present invention, it is characterized in that:
1.. the aluminium alloy extruded round ingot casting of strict check;
2.. conventional homogenising heat treatment;
3. enter the heating furnace heating, extruding and online air-blast quenching, extrudate goes out the nib temperature greater than 510 ℃;
4.. the aligning finishing;
5.. sawing, sorting, collection dress;
6.. pressing: each both sides is had the inserting press combined type module radiator that is constituted after enhancement mode module heat radiator that is constituted after the slot monomer accumulation of heat substrate that can peg graft is mutually each other pegged graft or the monomer fin that has hollow lattice structure and whole accumulation of heat substrate are pegged graft, under the vertical load effect of forcing press, it is pressed together, the plastic flow of even compression has all taken place in the interface of all monomer slots, and its compression strain value reaches 5%;
7.. strain-aging is handled: above-mentioned module heat radiator is carried out strain-aging handle, its institution of prescription is 5% compression strain, 180 ℃ of heating-up temperatures, temperature retention time 8-12 hour; After the pressing again the module heat dissipating modulator material after strain-aging is handled can reach the T10 state, its deep processing effect and product surface fineness can improve more than 20%
8.. the module heat radiator finished product, the heat spreader module after above-mentioned strain-aging is handled can obtain value-added T10 state mechanical performance and machinability.
Above-mentioned operation makes module heat radiator obtain suitable mechanical bond intensity simultaneously, also introduces 5% compression strain for the aluminum alloy materials of extruding as-quenched.Module heat radiator changes artificial strain-aging heat treatment step over to after " pressing " assembling; So far by the optimum organization of operations such as solution heat treatment, quenching (high-temperature molding cooling) and artificial strain-aging, can make material obtain maximum intensity.
For setting up whole even timeliness heating processes of furnace charge in the stove, the heating furnace domestic demand is provided with sharp draft.The time interval controls of the highest and minimum temperature point has then been determined the reasonable shove charge capacity that a certain constant power heating furnace is allowed.Because heating cycle, total duration was set, should be controlled at the unlikely over-heating of goods at high temperature dot place, and the unlikely underheat of low warm spot place goods.
Pressing heat spreader module after this strain-aging is handled can obtain value-added T10 state mechanical performance and machinability; And be in the cooled extrudate of the historical high-temperature molding of heat treatment, then be more suitable for taking place " pressing " process operations of cold plastic deformation because of T4 plasticity storage in good condition.
Its advantage is: the module heat dissipating modulator material after strain-aging is handled can reach the T10 state, its mechanical performance and hardness number obviously promote " machinability " of having improved product, can realize that deep processing effect such as high-speed milling, boring and tapping and product surface fineness can improve more than 20% in the CNC operation.
