Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below will be in the embodiment of the present invention
Technical scheme be clearly and completely described.Unreceipted actual conditions person, builds according to normal condition or manufacturer in embodiment
The condition of view is carried out.Agents useful for same or the unreceipted production firm person of instrument, are the conventional product that can be obtained by commercially available purchase
Product.
Aluminium alloy radiator sectional material and its application, press quenching technique below to the embodiment of the present invention is carried out specifically
It is bright.
The press quenching technique of aluminium alloy radiator sectional material is comprised the following steps：It is 480~520 in mould heating-up temperature
DEG C, recipient temperature be 430~460 DEG C under conditions of, aluminum alloy round ingot is extruded, then using blowing device to extruding
The bottom of the aluminium alloy radiator sectional material for going out blows, and the wind speed of the bottom of aluminium alloy radiator sectional material is 40~50m/s, aluminium
The top of alloy heat-sink type material and the wind speed of both sides are 0m/s.
The main difficulty of aluminium alloy radiator sectional material is：Section bar wall thickness differs greatly, and most heavy wall is with most the ratio between thin-walled about
44, and section bar teeth portion tooth root not in one plane, the teeth portion left and right sides is also asymmetric, the weighing apparatus so aluminium stream has much difficulty in healing very much,
This also brings requirement very high to extrusion process, mould, press quenching technique.In the present invention, the setting of technological parameter is just
It is that, based on its complicated shape, limit temperature both ensure that appropriate extruding force, and in turn ensure that the dimensional accuracy of product；Quench online
Ignition technique ensure that disperse of the second phase particles in later stage ag(e)ing process is uniformly separated out.
The press quenching technique of aluminium alloy radiator sectional material is divided into four, upper and lower, left and right part, corresponds respectively to section bar
Top (i.e. the teeth portion of section bar), bottom and both sides：
The quenching wind speed of the teeth portion of shaped material of radiator is set to 0m/s, it is therefore an objective to reduce the teeth portion caused by quenching stress
Deformation；
The quenching wind speed of the both sides of shaped material of radiator is set to 0m/s, it is therefore an objective to reduce the both sides caused by quenching stress
The deformation of gear piece；
The bottom of shaped material of radiator uses online air blast quenching technique, and quenching wind speed is set to 40~50m/s, it is therefore an objective to protect
Demonstrate,prove the hardness of bottom.The wind speed of bottom is preferably 49~50m/s, more preferably 49.5m/s, and wind speed is bigger, the type that extruding is obtained
The cooling velocity of material is faster, and reinforcing effect is better, and bottom hardness is also higher.
In the present invention, aluminum alloy round ingot can be big specification 6XXX line aluminium alloy billets, such as 6061,6063.Blowing device
Blowing device common in the art or conventional can be utilized, air blower, fan, producer are according to the specific setting of own situation
Device for cooling of drying etc. is all right, as long as blowing device can be carried out quick and expired to the bottom of aluminium alloy radiator sectional material
The blowing of sufficient wind speed requirement.
When extruding large-size aluminum alloy billet, extrusion ratio is 9.0~9.2, and extrusion speed is 1~1.4m/
min.This kind of extrusion ratio and extrusion speed are that the production difficulty and production efficiency for combining large-size aluminum alloy shaped material of radiator come
Formulate, under the restriction of various conditions, this kind of extrusion ratio and extrusion speed can produce the preferable aluminium alloy radiating of mass
Type material.
The holding temperature of large-size aluminum alloy billet is initial temperature with 485~495 DEG C, past away from crowded at extruding from being close to
510~520 DEG C are gradually incremented at pressure.Heated with gradient temperature, according to 5 (DEG C/area) be incremented by, it is ensured that large-size aluminum alloy is justified
The constant temperature extruding of ingot.
It is by the online of above-mentioned aluminium alloy radiator sectional material present invention also offers a kind of aluminium alloy radiator sectional material

Present invention also offers by aluminium alloy radiator sectional material obtained in above-mentioned press quenching technique.
Embodiment three
The press quenching technique of the aluminium alloy radiator sectional material that the present embodiment is provided, comprises the following steps：In mould heating
Temperature be 490 DEG C, recipient temperature be 450 DEG C under conditions of, the aluminum alloy round ingot of big specification 6061 is extruded, during extruding squeeze
Pressure ratio is 9.1, and extrusion speed is 1.1m/min, after extrusion, using 300 pairs of aluminium alloy heat radiator types for squeezing out of blowing device
The bottom of material blows, and the wind speed of the bottom of aluminium alloy radiator sectional material is 45m/s, the top of aluminium alloy radiator sectional material and
The wind speed of both sides is 0m/s.
Wherein, blowing device 300 is arranged at the lower section of aluminium alloy radiator sectional material, and blowing device 300 includes fan body
310 and drainage part 320, referring to Fig. 1, one end of drainage part 320 is connected with the center of fan body 310, the other end be from
Spiraled extensions towards aluminium alloy radiator sectional material by end and around the central axis perpendicular to ground, drainage part 320 is with toward
The width of the 5cm that heart axis direction extends.That is, the plate that drainage part 320 extends just as a 5cm bending wide.Drainage
The setting of part 320, can play a part of wind direction guiding, and under conditions of not by other equipment, to reach, " aluminium alloy radiates
The bottom wind speed of type material is 45m/s, and the wind speed of top and both sides is 0m/s " condition.
After the blowout wind of fan body 310, because fan body 310 is conventional, also including shell and flabellum, drainage part
320 are mounted on shell, when flabellum is rotated, blow out wind, apart from the closer location of fan body 310, wind direction skew, wind
Can spread, its gear piece that aluminium alloy radiator sectional material may be blown to along the edge of aluminium alloy radiator sectional material, and it is this kind of
Situation will be avoided, so drainage part 320 includes integrally formed upper-part 321 and lower component 322 again.Lower component 322 with
Fan body 310 is connected, and the diameter that spirals of lower component 322 gradually increases towards the direction away from fan body 310, upper-part 321
The diameter that spirals be gradually reduced towards away from the direction of lower component 322, the maximum of drainage part 320 diameter that spirals radiates less than aluminium alloy
The bottom width of type material, and, lower component 322 is less than outer rim 324 near the inner edge 323 of central axis, and upper-part 321 is close to
The inner edge 323 of central axis is higher than outer rim 324, referring to Fig. 2.That is, drainage part 320 is overall in narrow, middle wide up and down
Shape, so the maximum of drainage part 320 is spiraled, diameter is also just in medium position.After fan body 310 blows out wind, wind is in drainage
Under the shape effect of the lower component 322 of part 320, the medium position of drainage part 320 is gradually diffused into, and due to the width of medium position
Degree is less than the bottom width of aluminium alloy radiator sectional material, it is possible to reducing wind to the general of aluminium alloy radiator sectional material gear piece
Rate.And because the diameter that spirals of the and then upper-part 321 of drainage part 320 is gradually decreased, so the effect gathered is served, will
The bottom for draining into aluminium alloy radiator sectional material of wind convergence property, so as to further avoid wind to shaped material of radiator gear piece
The occurrence of.
Wherein, the diameter that spirals being previously mentioned, is calculated with the outer rim 324 in drainage part 320.
Present invention also offers by aluminium alloy radiator sectional material obtained in above-mentioned press quenching technique.
