Description
Technical field
The utility model relates to the quenching technology fields of extrusion aluminum-type material, more particularly to a kind of quenching on line device.This
Outside, the utility model further relates to a kind of extruder including above-mentioned quenching on line device.
Background technique
Other than the performance of material itself, press quenching technological parameter also has significant impact to aluminum profile performance, wherein
It mainly include the type of cooling, cooling velocity and quenching delay time etc..Press quenching technological parameter is studied to the shadow of profile performance
It rings, there is important meaning if appropriate for given quenching cooler, and the reasonable technological parameter of formulation to the alloy is evaluated
Justice.
The quenching of extrusion aluminum-type material is to obtain one of the key technology of high quality aluminum profiles.Aluminum profile generally requires higher
Intensity, good surface quality, the appearance that the aluminum profile in construction and decoration need also be beautiful.Reasonable effective quenching technical
And the mechanical strength of aluminum profile can be improved in device, carries out water immediately after squeezing such as 6001 in 6000 series alloys at 500 DEG C
Cold quenching processing, process rapidly and uniformly cool down, and the equally distributed solid solution phase of M92Si is generated in AI, can be obtained very high
Intensity will result in that M92Si precipitated phase is uneven or less but if dealing with improperly, and this reduces the intensity of aluminum profile.Cause
This extrusion aluminum-type material quenching technology and device become aluminum extrusion process important topic in the urgent need to address.
Traditional aluminium profile quenching technique is that quenching treatment is realized using out-line quenching furnace, this technique have energy consumption high and
The disadvantages of production cycle is long.
The type of cooling for squeezing press quenching mainly has water cooling, air-cooled and mist cold, and wherein the intensity of cooling of water cooling is more other
The intensity of cooling of two kinds of types of cooling is bigger.It is satisfied in order to obtain if its profile is thicker to the higher alloy of quenching sensitive
Intensity need to use water quenching, may will form steam thin layer during water quenching, the cooling velocity of profile part be caused to reduce, from
And product is caused to distort, such case is easiest to occur under conditions of static sink quenches.
Using slowly quenching cooling velocity after extruding, unfavorable shadow can be generated to the toughness of certain Al-Mg-Si system alloys
The fracture mode of 6060 aluminium alloys can be made when cooling velocity changes to 200 DEG C/s from 4.5 DEG C/s by ringing such as 6060 aluminium alloys
Become 90% transgranular fracture from 90% grain boundary fracture, while v-notch notched bar impact strength is correspondingly from 18J/cm2It is increased to 27J/
cm2, this brittle behaviour is due to Slow cooling at a temperature of extrusion forming, caused by generation crystal boundary area is degraded.Rapid cooling also can
The stress-corrosion cracking for leading to Al-Zn-Mg system alloy, such as Al-4.8Zn-1.2Mg alloy and Al5.35Zn-1.25Mg alloy
Maximum quenching velocity is 5 DEG C/s, this quenching velocity is significantly lower than the maximum quenching velocity that 7004 aluminium alloys are recommended to use
20℃/s。
Successfully to realize extruding press quenching, transfer time of the profile from mould outlet to quenching area is most important.Thing
Critical transfer time is not a constant in reality, and in addition to alloy property, it is also related with product section thickness and shape, product
Specific surface area is bigger or thickness is thinner, and required critical transfer time is shorter.
But existing press quenching device setting certain distance after front-axle beam outlet, it is certain in this way to require performance ratio
The minimum requirements of quenching effect has been not achieved in the temperature that higher aluminium enters aluminium when quenching unit is quenched.
In conclusion how to efficiently solve transfer time of the profile from mould outlet to quenching area it is longer the problems such as, be
Those skilled in the art's urgent problem at present.
