Abstract
The invention discloses an aluminum alloy section bar quenching apparatus. The aluminum alloy section bar quenching apparatus comprises a fan, a medium shell cavity with an upper open-ended end and a lower open-ended end; an air outlet surface of the fan faces downwardly; the internal diameter of the upper open-ended end of the medium shell cavity is greater than the internal diameter of the lower open-ended end of the medium shell cavity; and the upper open-ended end of the medium shell cavity is jointed on the air outlet surface. The aluminum alloy section bar quenching apparatus employs air-cooled cooling for cooling and hardening the aluminum alloy section bar, the deformation of the aluminum alloy section bar with thin wall thickness cannot be generated even the aluminum alloy section bar quenching apparatus is used for the aluminum alloy section bar with the thin wall thickness, a hollow cavity can be taken as a wind direction quantification rack, the wind direction and air quantity of the fan are concentrated on the aluminum alloy section bar which are required for being cooled and hardened, the power consumption of the aluminum alloy section bar quenching apparatus is reduced, so that energy saving function is realized. At the same time, a discharge hatch baffle plate of an extruder is arranged, so that the problem that temperature at the discharge hatch of the extruder is reduced due to wind flowing to the discharge hatch of the extruder.
Description
Technical field
The present invention relates to aluminium alloy production and processing technical field, more particularly to a kind of aluminum alloy section quenching device.
Technical background
At present during aluminium alloy extrusions is produced, it is related to extrusion process, its specific operating process is that aluminium alloy is extruded using extruder.Aluminium alloy after extruding is formed aluminium alloy extrusions.But these aluminium alloy extrusions also need to carry out cooling stiffened using quenching unit.And quenching unit is generally located on extruder discharge outlet, and it typically is a water cooling plant.When aluminium alloy extrusions is through water cooling plant, aluminium alloy extrusions rapid cooling can be allowed.But, the aluminium alloy extrusions relatively thin for wall thickness, when cooling stiffened is carried out using water cooling plant, because cooling rate is too fast deformation can be brought it about.
The content of the invention
The technical problem to be solved is to provide a kind of aluminum alloy section quenching device, and even with its aluminium alloy extrusions relatively thin to wall thickness cooling stiffened is carried out, and is also not result in the aluminium alloy deformation.
In order to solve above-mentioned technical problem, the technical solution used in the present invention content is as follows：
A kind of aluminum alloy section quenching device, it includes the middle shell cavity of fan and upper/lower terminal opening；The air-out of the fan faces down；The upper end open internal diameter of middle shell cavity is more than middle shell cavity lower ending opening internal diameter；The upper end open of the middle shell cavity is socketed on the outlet air surface.
The aluminum alloy section quenching device of the present invention carries out wind cooling temperature lowering using fan to aluminium alloy extrusions, and the speed of wind cooling temperature lowering be 300 degrees Celsius/it is per minute, temperature fall time is longer, even if so carrying out cooling stiffened using the aluminum alloy section quenching device of the present invention aluminium alloy extrusions relatively thin to wall thickness, the aluminium alloy extrusions that also wall thickness will not be allowed relatively thin is deformed because of rapid cooling.Meanwhile, the middle shell cavity of the present invention as the quantitative frame of wind direction, can be such that the wind direction and air quantity of fan concentrates on above the aluminium alloy extrusions for needing to cool down stiffened, reduce the power consumption of aluminum alloy section quenching device, be conducive to energy-conservation.
In order to avoid wind is to extruder discharging opening, so as to reduce the temperature of extruder discharging opening, it is preferable that the aluminum alloy section quenching device of the present invention also includes an extruder discharging opening baffle plate；The upper end of extruder discharging opening baffle plate is fixedly linked with middle shell cavity, and shape has angle；The angle is more than 45 degree, but less than or equal to 90 degree.
Preferably, the middle shell cavity is a funnel-shaped structure.
Compared with prior art, the present invention produces following beneficial effect：
The aluminum alloy section quenching device of the present invention carries out cooling stiffened using wind cooling temperature lowering to aluminium alloy extrusions, even if applying on the relatively thin aluminium alloy extrusions of wall thickness, also it is not result in the relatively thin aluminium alloy extrusions deformation of wall thickness, and the hollow cavity of the present invention can be used as the quantitative frame of wind direction, the wind direction and air quantity for making fan is concentrated on above the aluminium alloy extrusions for needing to cool down stiffened, the power consumption of aluminum alloy section quenching device is reduced, is conducive to energy-conservation.Meanwhile, the present invention is also provided with extruder discharging opening baffle plate, it is to avoid because wind reduces the temperature of extruder discharging opening to extruder discharging opening.
Description of the drawings
Fig. 1 is the structural representation of the aluminum alloy section quenching device more preferably embodiment of the present invention.
As shown in figure 1, the aluminum alloy section quenching device of the present invention, it includes the middle shell cavity 2 of fan 1 and upper/lower terminal opening；The outlet air surface 11 of the fan 1 is down；The upper end open internal diameter of middle shell cavity 2 is more than the lower ending opening internal diameter of middle shell cavity 2；The upper end open of the middle shell cavity 2 is socketed on the outlet air surface.
Specific embodiment
The aluminum alloy section quenching device of the present invention carries out wind cooling temperature lowering using fan 1 to aluminium alloy extrusions, and the speed of wind cooling temperature lowering be 300 degrees Celsius/it is per minute, temperature fall time is longer, even if so carrying out cooling stiffened using the aluminum alloy section quenching device of the present invention aluminium alloy extrusions relatively thin to wall thickness, the aluminium alloy extrusions that also wall thickness will not be allowed relatively thin is deformed because of rapid cooling.Meanwhile, the middle shell cavity 2 of the present invention as the quantitative frame of wind direction, can be such that the wind direction and air quantity of fan 1 concentrates on above the aluminium alloy extrusions for needing to cool down stiffened, reduce the power consumption of aluminum alloy section quenching device, be conducive to energy-conservation.
In order to avoid wind is to extruder discharging opening, so as to reduce the temperature of extruder discharging opening, specifically, the aluminum alloy section quenching device of the present invention also includes an extruder discharging opening baffle plate 3；The upper end of extruder discharging opening baffle plate 3 is fixedly linked with middle shell cavity 2, and forms an included angle A；The included angle A is more than 45 degree, but less than or equal to 90 degree.When using, the position that the aluminum alloy section quenching device of the present invention is moved to can make extruder discharging opening baffle plate 3 block extruder discharging opening just carries out wind cooling temperature lowering to aluminium alloy extrusions.Specifically, the middle shell cavity 2 is a funnel-shaped structure.
For a person skilled in the art, technical scheme that can be as described above and design, make other various corresponding changes and deformation, and all these changes and deformation all should belong within the protection domain of the claims in the present invention.
