Description

Technical Field

[0001] The utility model relates to the field of aluminum profile production, in particular to a rapid cooling device for aluminum profile production. Background Art

[0002] Aluminum profile is an alloy material with aluminum as the main component. Aluminum rods are obtained by hot melting and extrusion to obtain aluminum materials with different cross-sectional shapes. However, the proportion of the added alloy is different, and the mechanical properties and application fields of the industrial aluminum profiles produced are also different.

[0003] During the extrusion molding process, the aluminum rod itself has a high temperature, and a large amount of heat is generated under the action of extrusion, resulting in a high temperature of the aluminum profile after molding. Therefore, the aluminum profile needs to be cooled. The conventional cooling method is spray cooling. For example, patent number 2022225908769 is an aluminum profile cooling device, which introduces a cooling device that can spray and cool aluminum profiles during transmission. However, it is found during operation that although this method can effectively reduce the surface temperature of the aluminum profile, the side of the aluminum profile in contact with the conveyor belt cannot be sprayed with cooling water, so the temperature reduction rate is reduced, resulting in a large temperature difference between various parts of the aluminum profile, which is prone to thermal stress and causes the aluminum profile to break. Utility Model Content

[0004] The utility model is to solve the technical problems mentioned in the above background technology, and proposes the following technical solutions:

[0005] A rapid cooling device for aluminum profile production includes a workbench, a transmission trough is arranged on the workbench, a plurality of transmission rollers are arranged on the transmission trough, the left and right ends of the plurality of transmission rollers are rotatably connected to the left and right sides of the transmission trough respectively, a semicircular cover is arranged on the workbench, a plurality of spray heads are arranged in the middle of the top of the semicircular cover, the plurality of spray heads are connected to a first water pipe, one end of the first water pipe passes through the semicircular cover, a plurality of high-pressure spray heads are arranged at the bottom of the transmission trough, the high-pressure spray heads are located below the transmission rollers, the high-pressure spray heads are connected to a second water pipe, one end of the second water pipe passes through the workbench and is connected to the outside.

[0006] Preferably, the semicircular cover is provided with an exhaust hole, and the exhaust hole is provided with an exhaust pipe.

[0007] Preferably, high-temperature steam blocks are respectively provided at the front and rear ends of the semicircular cover.

[0010] The beneficial effects of the utility model are:

[0011] 1. By setting a semicircular cover and a spray head inside the semicircular cover, the aluminum profile passing through the semicircular cover can be sprayed to cool it down. A high-pressure nozzle is set at the bottom of the transmission trough on the workbench, and the aluminum profile above the transmission roller can be sprayed to cool it down to prevent uneven cooling of the aluminum profile and excessive local temperature, which will cause thermal stress in the aluminum profile and lead to the fracture of the aluminum profile.

[0012] 2. By arranging high-temperature steam blocks at the front and rear ends of the semicircular cover, it is possible to prevent the high-temperature steam generated during spray cooling from burning the staff.
