Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy product processing, and relates to a water spraying structure for quenching aluminum alloy profiles, in particular to a water spraying nozzle installation structure for quenching. Background Art

[0002] Online quenching means that after the profile is extruded and formed by an extruder, it is directly sprayed with water for quenching, and then the quenched profile is conveyed away. Thus, the process of transporting to a quenching furnace for quenching in the prior art is improved, and the production effect of the profile is improved, especially suitable for the production of some 6XXX aluminum alloys with a large temperature adaptation range. At present, the structure of inner and outer sleeves with a water cavity can meet the passage of the profile and the water flow channel. When the traditional nozzle is installed on the above-mentioned structure of the inner and outer sleeves, the front end of the nozzle will extend into the inner and outer sleeves. When the profile is extruded and moves forward, it is easy to touch the protruding front end of the nozzle, which will not only cause problems in hindering the forward movement of the profile, but also cause problems of scratching or wearing the surface of the profile by the front end of the nozzle. To sum up, there is an urgent need for a new nozzle that can avoid damaging the profile, does not affect the forward movement of the profile, and can adjust the water spraying angle.
