Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, and particularly relates to a processing and cooling device for aluminum alloy profiles. Background Technique

[0002] Aluminum alloy profiles are alloys with aluminum as the base material and a certain amount of other alloying elements added. They are one of the light metal materials and are one of the most widely used non-ferrous metal structural materials in industry. Usually, they are first processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then processed through cold bending, sawing, drilling, assembling, coloring and other processes. At present, aluminum alloy profiles have been widely used in aviation, aerospace, automobiles, machinery manufacturing, ships, construction, decoration and chemical industries.

[0003] Aluminum alloy profile extruders are mainly used to produce aluminum alloy profiles of different specifications. The processing method is to extrude aluminum rods on a fixed forming die. When the aluminum alloy profiles are extruded from the outlet of the aluminum rod extruder, the temperature of the aluminum alloy profiles is very high, and the overall cooling of the aluminum alloy profiles is required. Among them, cooling requires the use of a cooling device.

[0004] The existing processing and cooling devices for aluminum alloy profiles usually use two cooling methods, air cooling and water cooling, to cool the aluminum alloy profiles. The air cooling method is suitable for the initial cooling of the profiles because the medium temperature is relatively high, which can effectively reduce the temperature difference between the medium and the profiles. The water cooling method has a lower medium temperature and is suitable for the later cooling of the profiles. However, the cooling methods of the existing processing and cooling devices for aluminum alloy profiles are relatively single, and most of them only have one cooling method of air cooling or water cooling, and cannot realize the integrated operation of air cooling and water cooling. Therefore, two sets of cooling devices, an air cooling device and a water cooling device, need to be set up and used in cooperation to complete the cooling and temperature reduction treatment of the aluminum alloy profiles, resulting in an increase in floor area, cumbersome operation, and poor cooling effect on the aluminum alloy profiles, affecting the production quality of the aluminum alloy profiles. Therefore, a processing and cooling device for aluminum alloy profiles needs to be designed to solve the above problems.

[0005] The information disclosed in this background technical section is only intended to increase the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art.
