Embodiment Construction

[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] As shown in the figure, the aluminum alloy anti-collision profile for large car body in this embodiment is a hollow tube structure, including a central tube body 1 and an extension tube body 2, and the cross section of the central tube body 1 is octagonal. There are four extension tube bodies 2, which are arranged at intervals on the four tube walls of the octagonal central tube body and correspond to the tube walls to form a hexagonal tube body. The structure is stable, has good anti-collision performance, has good energy absorption effect in severe impacts, and has good cushioning performance, which effectively solves the problems of poor plasticity and high mechanical performance of existing large-scale car body anti-collision profiles. The problem.

[0018] As a further improvement of the above solution, the extension pipe body ...

Abstract

The invention discloses an aluminum alloy anti-collision profile for a large car body and a production process thereof. By setting a special profile structure, the profile has a good anti-collision performance, and has a good energy absorption effect in a severe impact, and has Very good cushioning properties. By adopting appropriate aluminum alloy materials, extrusion temperature, extrusion coefficient, cooling method, straightening method and aging method, not only the production efficiency and yield of the whole process are improved, but the cost is reduced; The collision profile has medium mechanical properties, excellent plasticity and good cushioning performance; it meets the requirements of large car bodies.

Description

technical field [0001] The invention belongs to the field of processing aluminum alloy profiles, and in particular relates to an aluminum alloy anti-collision profile for a large car body and a production process thereof. Background technique [0002] The development theme of vehicle body material technology in the world today is lightweight, high performance, safety, environmental protection and energy saving. 6008 alloy has medium strength, good plasticity, corrosion resistance and welding performance. It is mainly used to produce solid and hollow extruded products. Although the composition plays a major role in the properties of the alloy, different heat treatment methods and processes sometimes affect the Alloy properties play a major role. Most of the existing anti-collision profiles for large car bodies in my country have the problems of poor plasticity and high mechanical property values. Therefore, balancing plasticity and improving mechanical property values ​​are ...
