Description

A kind of multi-functional press quenching system of Aluminum alloy extrusion material

Technical field

The utility model belongs to aluminium alloy press quenching technical field, and in particular to a kind of Aluminum alloy extrusion material it is multi-functional Line quenches system.

Background technique

Aluminium alloy extruded press quenching technology can simplify production procedure, shorten the production cycle, improves production efficiency, reduces Production cost, part 2xxx, 7xxx system and almost all of common 6xxx line aluminium alloy can be quenched online using squeezing at present Ignition method production.Guarantee the mechanical property of press quenching profile, it is necessary to the cooling speed of some strength at extruder outlet Degree is quenched, and to guarantee to obtain supersaturated solid solution, the tiny precipitation of hardening constituent, it is strong to play disperse in subsequent ag(e)ing process Change effect.But quenching cooling velocity is too fast, then the even performance of each position inhomogeneous cooling of profile is obvious in quenching process, be easy to cause Profile deforms after quenching, and especially big specification profile press quenching problem on deformation is very prominent.Therefore, it is necessary to the conjunctions according to product The composite factors such as gold, cross sectional shape, wall thickness, using suitable hardening media and parameters of quenching.

According to function division, at present press quenching system be broadly divided into five kinds: wind quenching fire, wind+water spray quenching, Wind+water spray+mist quenching, standing wave quenching, standing wave+water spray quenching.There is presently no collection wind+mist+water spray+standing waves four to quench greatly The system of fiery function or four big functions are unable to normal use because existing wind quenching unit and standing wave quenching unit can generate it is dry It relates to, wind quenching fire needs to have several air outlets in the upper surface of quenching channel and two sides design, is generally configured to one or more Fan housing movable up and down, above and the air outlets of two sides blown out out of fan housing；And standing wave quenching must be the two of quenching channel Two shelves water plates are designed in side, cause the fan housing of wind quenching fire that can not decline, or even if are designed to fan housing and shelves water plate in lateral alternate Position achievees the purpose that fan housing can be declined, but the wind quenched also can not can normally be arranged because of two side plate washers of standing wave quenching Out.And the product category of the large-size extruder production modernized is more, needs the big quenching function ability of wind+mist+water spray+standing wave four Meet production requirement, can only be further added by a moveable standing wave on the basis of wind+water spray+mist quenching system at present and quench Fiery sink, sink is hung away, standing wave is needed again to load onto sink when quenching when not needing standing wave quenching, is loaded and unloaded sink back and forth and is led It causes labor intensity to increase and exist very big security risk, does not meet the production requirement of modernization.

In addition, liquid will not soak hot surface, and only be formed on one according to Leidenfrost effect The heat conduction velocity of vapor film, vapor film is slow more than liquid water.In standing wave quenching, surface meeting when the product of high temperature passes through water Steam blanket is formed, if the agitation of standing wave water is insufficient or uneven, steam blanket can not be destroyed, cooling effect can drop significantly It is low.And existing standing wave quenching is by spraying the water column of low-pressure from bottom to form waterwall and gentle agitation effect, therefore Its hydraulic pressure is smaller, stirring is insufficient, uneven, causes that standing wave water level is lower, cooling capacity is weaker, can through hardening maximum product rule Lattice are smaller, and the production requirement of large-size extruder is not achieved.

Through retrieving, Chinese patent, application number 201721430794.0, multi-functional backward and forward extrusion aluminum profile press quenching dress Set, the device can realize integrate air-cooled, spray, mist is cold and four kinds of refrigerating functions of standing wave, but the device is lacked there are following Point: first product is realized when only standing wave quenches and is quenched in traction, other quenching modes are crowded since dragger can not reach Press exit cannot achieve first product and quench in traction；The standing wave of the device is from beneath ejection " Qiang Shui ", pressure Smaller (big water can fly out come), mixing effect difference and inhomogeneous cooling is even, can through hardening maximum product specification it is smaller, be not achieved The production requirement of large-size extruder.

Chinese patent, application number 201210565791.3, a kind of novel reversed aluminium extruding machine quenching system and quenching side Method, the quenching system according to the wall thickness size of aluminium material, can choose the standing wave water cooling of the water mist or water pipeline of nozzle, quench cold But after, not only temperature drops to claimed range, and the uniform deflection of mechanical performance after the quenching of aluminium material can be made small.The quenching system System have the disadvantage in that cannot achieve it is air-cooled；It cannot achieve first product to quench in traction；Standing wave only sprays high pressure from bottom Water (avoids powder-refining with water from going out) by lid, there is a problem of that inhomogeneous cooling is even.

In conclusion there is also following disadvantages for existing quenching unit:

1, the side plate washer of existing standing wave quenching and wind facies interference cause wind, mist, water spray quenching and standing wave to quench four big function Normal use can be coexisted or be unable to simultaneously, or needs artificial handling standing wave quenching sink or side plate washer, is unable to satisfy the modern times Change the production requirement of large-size extruder.

2, the water of standing wave quenching is only sprayed from bottom, and water level is too low to cover heavy in section product, and hydraulic pressure is too Low and outlet mal-distribution, can not all destroy the steam blanket of product surface, lead to that cooling capacity is too weak, inhomogeneous cooling It is even, it is unable to satisfy the quenching demand of the products such as large scale rod bar.

3, draw first product when, press quenching cover can not decline, cause first product because can not normal quenching and report It is useless.
