[0002] At present, the online quenching cooling device used for extruded profiles can only meet the cooling requirements of products with simple shapes and small wall thickness differences. However, for products with complex shapes and large wall thickness differences, it is impossible to accurately adjust the cooling speed of each part of the profile, resulting in uneven mechanical properties, dimensional tolerances, twisting, bending and other defects of the product, which in turn causes the appearance of waste products, increases manufacturing costs, and even makes it impossible to produce qualified products.

[0003] Therefore, there is an urgent need for an online quenching and cooling device that can accurately control the cooling rate of each part of an extruded profile with a complex shape. Summary of the invention

[0006] The water spray pipe is connected and fixed to the track via a fixing buckle.

[0013] Figure 1 It is a schematic diagram of the structure of the present invention; Figure 2 It is a front view of the present invention; Figure 3 It is a side view of the present invention. DETAILED DESCRIPTION

[0014] like Figures 1 to 3 As shown, an auxiliary device for online quenching and cooling of extruded profiles comprises two longitudinal rails 2 parallel to each other, an upper transverse rail 1 is arranged at the upper end of the longitudinal rail 2, a lower transverse rail 3 is arranged at the lower end of the longitudinal rail 2, a plurality of water spray pipes 4 are arranged on the longitudinal rail 2, the upper transverse rail 1 and the lower transverse rail 3, the front and rear ends of the water spray pipes 4 are respectively connected and fixed to the rails arranged at the front and rear ends, and the water spray pipes 4 are connected and fixed to the rails through fixing buckles 6. The space between the water spray pipes 4 and the rails is a space for placing the extruded profiles, and a plurality of nozzles 5 for spraying coolant are arranged on the pipe wall of the water spray pipes 4. A flow control valve 7 is arranged at the front end of the water spray pipes. The water spray pipes 4 and the rails are made of stainless steel, the nozzles 5 are connected and fixed to the water spray pipes 4 by bellows, and the front end of the water spray pipes 4 is connected and fixed to the water pump. The position of the water spray pipes 4 is determined according to the shape of the extruded profiles.

[0015] When the extruded profile is cooled, first fix the longitudinal track 2 to one side of the profile in the quenching zone, then fix the upper transverse track 1 and the lower transverse track 3 to the longitudinal track 2, and then install the water spray pipe 4 to the upper transverse track 1, the lower transverse track 3 and the longitudinal track 2 through the fixing buckle 6. The number of water spray pipes 4 and the position of the water spray pipes 4 on the track are adjusted according to the shape of the extruded profile. The number and position of the water spray pipes 4 required for different extruded profiles are different. The front end of the water spray pipe 4 is connected and fixed to the water pump, and the water pump is placed in the cooling pool. Then open the water flow control valve 7 for machine production. During production, cooling water is sprayed out through the nozzle 5 on the water spray pipe 4 to cool the extruded profile. Since the position of the water spray pipe 4 is set according to the shape of the extruded profile, the extruded profile can be fully cooled. This auxiliary device can be suitable for quenching and cooling of various extruded profiles.

[0016] After the aluminum profile is cooled, the water flow control valve 7 is adjusted according to the shape of the product so that the cooling water is sprayed onto the profile in the required amount, thereby achieving accurate cooling of different parts of the aluminum profile and uniform cooling of the entire cross section of the profile. After the extrusion is completed, the cooling auxiliary device is removed. The cooling water after cooling the extruded profile is discharged into the collection pool below the device, and after cooling in the collection pool, it is discharged into the cooling pool for recycling.

[0017] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification made to the present invention by those skilled in the art without departing from the spirit of the present invention shall fall within the protection scope of the present invention.
