Description

Technical Field

[0001] The invention belongs to the technical field of aviation parts production, and in particular relates to a heat treatment device and method for aviation hinge thin-wall extrusion parts. Background Art

[0002] The role of heat treatment devices in the production of thin-walled extrusions of aviation hinges is mainly reflected in the following aspects: 1) Heat treatment is a processing method that changes the properties of materials by heating and cooling. It is mainly used for the preparation of metal and alloy materials, as well as the manufacture of parts in industrial production. In the production process of thin-walled extrusions of aviation hinges, the heat treatment device can heat, insulate and cool the workpiece, thereby changing its internal metallographic structure. This change can significantly improve the hardness, toughness, strength and corrosion resistance of the material, so that the thin-walled extrusions of aviation hinges have better mechanical and physical properties, meeting the requirements of high strength, high reliability and long life in the aviation field. 2) In the production of thin-walled extrusions of aviation hinges, due to the thin material and complex shape, it is easy to deform during the processing. The heat treatment device can effectively reduce the residual stress inside the workpiece through precise temperature control and cooling rate adjustment, thereby reducing the risk of deformation. 3) The heat treatment device also plays a role in optimizing the production process in the production of thin-walled extrusions of aviation hinges. Through heat treatment, the processing performance and mechanical properties of the material can be adjusted to make it more suitable for subsequent cutting, grinding and assembly processes. In addition, heat treatment can solve stress problems during welding and eliminate residual stress and deformation after welding, thereby improving the efficiency of the entire production process and product quality.

First, it cannot realize the flipping of the thin-walled extrusions of aviation hinges during the heat treatment process, and the heat treatment effect is not ideal; second, it cannot open the two leaves of the thin-walled extrusions of aviation hinges during the heat treatment process, and cannot reliably clamp the thin-walled extrusions of aviation hinges without hinge shafts installed, which affects the heat treatment efficiency. Therefore, it is necessary to optimize and improve the heat treatment device of traditional thin-walled extrusions of aviation hinges. Summary of the invention
