Ultrathin-wall profile

Abstract

The invention discloses an ultrathin-wall profile. The ultrathin-wall profile is formed by metal aluminum through integral extrusion forming and comprises a profile body of a lengthwise groove type structure. The profile body comprises a top segment, a connecting segment and a bottom segment which are connected end to end. The ends, deviating from the connecting segment, of the top segment and thebottom segment protrude and extend to form a first limiting portion and a second limiting portion which are arranged oppositely. The top segment is concaved downwards to be provided with a first sliding groove. A third limiting portion is arranged between the first sliding groove and the second limiting portion. The center of the connecting segment is concaved inwards to be provided with a secondsliding groove. A first limiting groove is formed in the side, deviating from the connecting segment, of the second sliding groove in a concaved manner. A fourth limiting portion is arranged at the end, close to the connecting segment, of the inner side of the bottom segment in a convex manner. A fixed portion is arranged at the end, close to the second limiting portion, of the inner side of thebottom segment in a convex manner. A second limiting groove is formed in the fixed portion in a concave manner. A U-shaped prefabrication hole is formed in one end of the top segment. The ultrathin-wall profile is simple in structure and can be mounted and fixed rapidly.

Description

technical field [0001] The application relates to the field of metal forming, in particular to an ultra-thin-wall profile. Background technique [0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot-melting and extruding aluminum rods. Aluminum profiles are widely used in various production departments, such as automobiles, motorcycles, bicycle accessories, building materials (locks and door handles), hardware and electrical appliances, etc. The aluminum profile is easy to damage due to its low strength. In order to improve the strength, fracture toughness and fatigue performance of the aluminum profile, the most direct way is to increase the purity of the raw material, but that will increase the processing difficulty of the raw material, and the material cost can only be increased, and It may be difficult to realize in the metallurgical process. In addition, in the application of existing aluminum profiles, especially in the...

Problems solved by technology

The aluminum profile is easy to damage due to its low strength. In order to improve the strength, fracture toughness and fatigue performance of the aluminum profile, the most direct way is to increase the purity of the raw material, but that will increase the processing difficulty of the raw material, and the material cost can only be increased, and It may be difficult to realize in the metallurgical process. In addition, in the application of existing aluminum profiles, especially in the application of circular aluminum profiles, the connection between profiles is difficult
