Abstract

The invention relates to the technical field of aluminum alloy processing, in particular to an aluminum alloy forced sizing device and an aluminum alloy heat treatment method. The aluminum alloy forced sizing device comprises a base and multiple single part clamps arranged linearly. Each single part clamp comprises a framework, a locating block and two straightening parts, wherein the framework isperpendicular to the base and allows an aluminum alloy profile to penetrate, and the locating block and the two straightening parts are arranged on the framework. The locating blocks abut against theupper surface of the aluminum alloy profile in the frameworks, and the two straightening parts of each single part clamp abut against the two side faces of the aluminum alloy profile in the frameworks in a one-to-one correspondence manner. According to the aluminum alloy forced sizing device, an aluminum alloy product can be sized, and deformation is prevented from happening during heat treatment. The aluminum alloy heat treatment method comprises the steps that the aluminum alloy forced sizing device is adopted for locating the aluminum alloy profile, and then quenching treatment or aging treatment or quenching and aging treatment is carried out. According to the method, the problem of bending deformation happening during aluminum alloy heat treatment can be effectively solved, the aluminum alloy product good in straightness can be obtained, and the requirement of aviation use can be met.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing, in particular to an aluminum alloy forced shaping device and an aluminum alloy heat treatment method. Background technique [0002] At present, commercial aircraft are developing in the direction of larger, faster, and longer life. The fierce competition in the market has forced aircraft manufacturers to put forward higher requirements for the design and material performance of aircraft structural parts. The design focus of aircraft has evolved from the initial static strength design to safe life design, safe life / damage safe design, safe life / damage tolerance design and durability / damage tolerance design. With the enlargement of the aircraft, the size of the structural parts of the aircraft is correspondingly increased, and the structural parts are developing in the direction of lighter, larger, higher performance, more reliable, longer life and lower cost, and the overall comp...
