Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy profile processing, and in particular relates to a rapid cooling device for aluminum alloy profile shaping. Background Art

[0002] Aluminum alloy profiles are commonly used profiles for doors and windows, industrial electrical equipment, building materials, etc. They are formed by hot-melting aluminum bars and then extruding them on a forming die. When extruded from the extrusion outlet, the high temperature will cause the aluminum alloy profile to be insufficiently hard, and the aluminum alloy profile needs to be finalized on a subsequent conveying device.

[0003] When cooling and shaping the aluminum alloy profile, generally after the aluminum alloy profile is extruded, it is first cooled in a water cooling device, then air-cooled and dried to shape, and after being pulled a certain distance on the conveyor roller by a traction mechanism, it is cut to a fixed length by a cutting mechanism.

[0004] Since the profiles directly enter the cooling water for cooling during transportation, the water cooling equipment must be of sufficient length. At the same time, condensed water will remain on the profiles after water cooling, which is not easy to air dry. Therefore, multiple fans must be configured along the transportation direction for air cooling and drying. The wind blown by the fans is difficult to cool the profiles evenly along the length direction, resulting in low overall cooling efficiency and a large overall space occupied by the equipment.
