Aluminum profile cooling process

Abstract

The invention discloses an aluminum profile cooling process in the technical field of aluminum profile cooling. A pipe frame, a motor and a water accumulation tank are included. A plurality of long round holes at equal intervals are formed in the periphery of the pipe frame, and the transverse long round holes and the vertical long round holes are formed in a staggered manner. The motor is fixedlyconnected to one end of a drive shaft, and the drive shaft is rotationally connected to the outer wall of the pipe frame through a load plate. A cooling mechanism, a speed change mechanism, a transmission mechanism and a high-pressure mechanism are included. The cooling mechanism is in sliding connection to the inner wall of the pipe frame through a sliding roller and the long round holes. The speed change mechanism is fixedly connected to the inner wall of the water accumulation tank. The transmission mechanism is fixed to the outer wall of the pipe frame. The high-pressure mechanism is fixed to the outer wall of the water accumulation tank. Aluminum profiles are formed in an extrusion manner, the aluminum profiles output from an extruder need to be cooled due to the high temperature, next-machining or treatment is facilitated, and the problems that under the common air cooling condition, the heat exchange coefficients of all parts of the profiles being in contact with air are equal,and due to different wall thicknesses or shapes, the heat dissipation speeds of all the parts are different are effectively solved.

Description

Technical field[0001]The invention relates to the field of aluminum profile cooling, in particular to an aluminum profile cooling process.Background technique[0002]Aluminum and its alloys have a series of excellent properties. In the application of metal materials, the application of aluminum is second only to the application of steel, ranking second. Especially after the Second World War, the military industry of aluminum materials turned to civilian industries, and then entered all aspects of people's lives, becoming an important basic material for developing the national economy and improving the people's material and cultural living standards. The social demand is growing rapidly, and the application field is constantly expanding. Aluminum profiles are all formed by extrusion. The aluminum profiles coming out of the extruder need to be cooled due to their higher temperature, which is convenient for the next step of processing or processing.[0003]However, in the current existing ...

Problems solved by technology

[0003] However, in the current existing technology, air cooling is usually used for cooling. In actual production, due to the limited space in the factory, the length of the cooling device is limited, and the cooling device is only equipped with a fan at the bottom of the aluminum profile. The lack of sufficient cooling of the aluminum profile is not conducive to the next step of processing; under ordinary air-cooled conditions, the heat transfer coefficients of each part of the profile in contact with the air are equal, but due to the difference in wall thickness or shape, the heat dissipation rate of each part is not Equal, so the heat dissipation speed of the thick-walled part or hollow tube is slower than that of the thin-walled part; for thick-walled aluminum tubes or aluminum rods, a simple water cooling method is used, that is, a simple water tank is used to completely immerse the aluminum in water. Rapid cooling. In this case, due to the different lengths of the aluminum profiles and the fixed size of the cooling pool, the practical range is small and the popularity is small. In addition, there is always a difference in immersion time when the aluminum profiles are immersed in the cooling pool. Deformation occurs; when water cooling is used, the simple water tank needs to be temporarily hoisted into the existing cooling device, and then the hose is temporarily connected for water supply. When changing the type of aluminum material, it is very troublesome to change the cooling method
