Aluminum alloy profile

Abstract

The invention provides an aluminum alloy section which comprises a circular-tube-shaped inner section and a circular-tube-shaped outer section, three forming grooves which are distributed at equal angles are formed in the outer circle face of the inner section, the outer section is arranged on the outer side of the inner section in a sleeving mode, three forming rails are arranged in a tube cavity of the outer section, and the three forming rails are arranged on the outer side of the inner section in a sleeving mode. A through hole is formed in the inner section bar, a lining pipe consistent with the through hole in length and size penetrates through the through hole of the inner section bar, three sets of forming grooves correspondingly formed in the periphery of the clamping groove are formed in the outer circle face of the section bar pipe, each set of forming groove is composed of two long groove units symmetrically formed in the two sides of the locking groove, and when the outer section bar pipe is arranged on the outer side of the inner section bar pipe in a sleeving mode, the inner section bar pipe can be clamped. The guide rail is used for applying pressure to the long groove unit, the long groove unit is forced to apply pressure to the locking groove, so that the reinforcing lining can be fixed in the pipe cavity of the profile pipe on the premise that welding is not needed, and due to the fact that the reinforcing lining does not need to be welded and assembled through a welding gun when being assembled into the profile pipe, operation is convenient, and meanwhile work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of seals, in particular to aluminum alloy profiles. Background technique [0002] Aluminum alloy tubular profiles are divided into circular tubular profiles, rectangular tubular profiles, elliptical tubular profiles and special-shaped tubular profiles according to the cross-sectional shape. In addition, its weight is light and easy to construct. In order to improve its strength, when it is used as a support (such as a column), it has a high bearing capacity, so the inner lining reinforcement of aluminum alloy material will be filled in its lumen. The more contact points of the lining with the inner wall of the lumen in the profile's lumen, the higher the profile's support strength. [0003] The lining with a slightly complex cross-sectional shape cannot be discharged simultaneously with the profile using a molding die on the molding machine. In actual production, the profile needs to be extruded by the mold...

AI Technical Summary

Problems solved by technology

[0003] The inner lining with a slightly complicated cross-sectional shape cannot be discharged on the molding machine at the same time with the profile. In actual production, the profile needs to be extruded by the molding machine through the matching mold, and then formed by another matching mold. The machine extrudes the inner liner, and finally welds the inner liner into the lumen of the profile. During the welding process of the inner liner into the lumen, due to the long size of the profile and the limited space in the lumen of the profile, the inner It is inconvenient to operate the welding torch when the lining is welded into the lumen, which affects its working efficiency
