A kind of environment-friendly high-toughness aluminum alloy profile and preparation method thereof

Abstract

The invention discloses an environment-friendly high-toughness aluminum alloy profile and a preparation method thereof. The preparation method is specifically smelted at a temperature of 690-730 degrees Celsius for 8 hours to obtain an aluminum alloy melt; through horizontal continuous casting, continuous extrusion, and heat treatment to obtain Aluminum alloy profile rough material, put the aluminum alloy profile on the push plate between the two protective plates of the aluminum alloy profile drilling equipment, the pipe sleeve is fixed on the support shaft by bolts, the position of the bottom plate is fixed, and the angle of the bottom plate is adjusted. The sleeve is fixed on the support shaft by bolts to fix the position of the bottom plate, and the second piston rod inside is controlled to move to the outside of the cylinder body through the second hydraulic cylinder, so that the push plate is pushed, and the third piston rod inside is controlled by the third hydraulic cylinder. The piston rod moves to the outside of the cylinder, and the third piston rod pushes the side wall of the aluminum alloy profile, so that the aluminum alloy profile is fixed between the two protective plates. There is no need to use special clamps to fix the aluminum alloy profile, and the fixing method is simple and firm .

Description

technical field [0001] The invention relates to the field of aluminum alloy profile preparation technology, in particular to an environment-friendly high-toughness aluminum alloy profile and a preparation method thereof. Background technique [0002] With the development of science and technology, my country has become the world's largest producer, exporter and consumer of aluminum extrusions. At present, my country's aluminum extrusion industry has entered a new stage of scale and technological upgrading, and is in an important period of change and transformation. Now the aluminum alloy industry has developed towards the direction of producing environmentally friendly, low energy consumption, and excellent alloy properties. Now an environmentally friendly high-toughness aluminum alloy profile is proposed. [0003] In the preparation process of the existing aluminum alloy profiles, a series of preparation processes such as drilling and grinding are required after the rough ...
