Problems solved by technology

Although the above methods can achieve certain effects, they all have their own limitations, and the scope of practical application is limited; moreover, there are many requirements for the mechanical properties of aluminum alloy profiles in industrial production, including yield strength, tensile strength , elongation, etc.
However, the existing technologies often can only improve one or two of the mechanical properties, and it is difficult to take care of both

Abstract

The invention provides a production method for 6082 aluminum alloy profiles. The production method obtains the aluminum alloy profiles through the steps of smelting casting, uniform heat treatment, extrusion, quenching, cutting, straightening, sawing, framing, aging and the like. By means of the production method, by controlling the feeding temperature, extrusion speed, outlet temperature in the extrusion step and the cooling rate in the quenching step in the production process of the aluminum alloy profiles, the mechanical properties such as yield strength, pull strength and elongation of thealuminum alloy profiles are improved, the pass rate of the aluminum alloy profiles is increased accordingly, and the fact that the subsequent production can be carried out smoothly is ensured.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metals, and in particular relates to a production method of 6082 aluminum alloy profiles. Background technique [0002] Aluminum alloys have been used more and more widely in today's industrial production. According to the different elements contained in aluminum alloys, aluminum alloys can be divided into nine categories from 1 to 9. Among them, the 6-series aluminum alloy is an alloy composed of Al, Si, and Mg. Furthermore, the 6082 aluminum alloy not only has the performance characteristics of high strength and good toughness of the 6-series aluminum alloy, but also has strong resistance to metal fatigue, and can be widely used. It has a good application prospect in key parts, functional parts and safety parts of automobiles. [0003] However, conventional 6-series aluminum alloys generally have the characteristics of low yield strength and tensile strength, and poor mechanical properties....
