Automatic aluminum profile machining line applying three-dimensional cooling bed

The invention relates to the technical field of aluminum material machining equipment, in particular to an automatic aluminum profile machining line applying a three-dimensional cooling bed, which comprises a conveyor belt, the three-dimensional cooling bed and an automatic sawing device, and the three-dimensional cooling bed comprises a support frame and a plurality of circulating conveying mechanisms; each circulating conveying device comprises a vertical plate, a bracket and two chain type transmission assemblies, two connecting arms are arranged on the bracket, the distance between every two adjacent sawing machines is adjusted by sliding the sawing machines, so that the distance between every two adjacent sawing machines is equal to the cutting length of the aluminum material, and therefore the aluminum material can be cut at the same time through the multiple sawing machines; by arranging the three-dimensional cooling bed, aluminum materials are cooled when the three-dimensional cooling bed ascends and
