Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of air cooling quenching, in particular to an air cooling device. BACKGROUND

[0002] In the mechanical field, quenching process is a kind of processing method with very wide application, quenching process is to heat certain metal material to certain temperature and keep certain time, changes its alloy organization, purpose is to improve the mechanical properties of alloy, increases corrosion resistance. At present, the mechanical property requirement of aluminium extrusion product is higher and higher, and higher appearance and dimensional accuracy are required, therefore, more aluminium alloy products that can be air-cooled are used in the form of online air cooling.

[0003] In the prior art, the air cooling quenching device of aluminium profile has the following shortcomings: (1) due to high temperature in production workshop (extrusion machine, bar furnace, die furnace and other heating equipment and weather influence), the indoor air of high temperature is sucked by the fan, and then the high-temperature aluminium profile is cooled, which can cause poor quenching effect, and to improve the air cooling effect, the power of the fan needs to be increased, thereby increasing the energy consumption of production, which is not conducive to energy saving and emission reduction; (2) the hot air sprayed by the fan not only reduces the quenching effect, but also deteriorates the working environment and affects the normal operation of workers.
