Molding production line for aluminum alloy profile and molding technology of aluminum alloy profile

Abstract

The invention discloses a molding production line for an aluminum alloy profile. The molding production line comprises an aluminum alloy profile molding device (1), a quenching device (2) and a tension straightening device (3) which are sequentially arranged from left to right. The aluminum alloy profile molding device (1) is composed of an extrusion cylinder (4), an extrusion oil cylinder (5), an extrusion pad (6) and a pad mold (7). A material extrusion chamber (8) is arranged in the extrusion cylinder (4). The extrusion pad (6) capable of sliding along the material extrusion chamber (8) is arranged in the material extrusion chamber (8). A piston rod of the extrusion oil cylinder (5) is arranged in the material extrusion chamber (8) in a penetrating manner and is connected with the extrusion pad (6). The pad mold (7) is arranged at the right end of the extrusion cylinder (4). A through groove (9) communicating with the material extrusion chamber (8) is formed in the pad mold (7). The invention further discloses a molding technology of the aluminum alloy profile. The molding production line and the molding technology have the beneficial effects that the manufactured aluminum alloy profile is high in mechanical strength, smooth in surface, free of internal residual stress and simple in technology.

Description

technical field [0001] The invention relates to the technical field of isothermal extrusion of aluminum profiles, in particular to a forming production line of aluminum alloy profiles and a forming process thereof. Background technique [0002] At present, with the advancement of aluminum extrusion technology and the rapid development of the national economy, the application of aluminum profiles in transportation, aerospace, industrial machinery, electronic equipment and other fields is increasing year by year, especially in my country's transportation industry towards lightweight and high-speed With the development in the direction of environmental protection, transportation vehicles such as subways, high-speed trains, light rails, and double-decker buses gradually adopt aluminum profiles. Existing aluminum alloy profiles are mainly formed by extrusion and cooled by air after forming, which has the defect of long cooling time, which reduces the production efficiency of alumi...

AI Technical Summary

Problems solved by technology

Existing aluminum alloy profiles are mainly formed by extrusion and cooled by air after forming, which has the defect of long cooling time, which reduces the production efficiency of aluminum alloy profiles, and residual internal stress remains inside, resulting in low mechanical strength

Therefore, the existing molding process is not popularized and adopted
