Embodiment

[0030] This embodiment proposes an aluminum alloy blade profile, which adopts figure 1 The process flow shown is made by the following steps:

[0031] S1. The width direction of the aluminum alloy blade profile to be manufactured is 198.39mm, the height direction is 24mm, and the cross-sectional area is 924.4mm 2 , in order to control the extrusion ratio between 30 and 60, an extruder with a corresponding diameter of the extrusion cylinder is selected for extrusion, and the extrusion ratio is calculated to be 46.84, which meets the extrusion requirements. The extrusion machine is equipped with an online air-cooled quenching device, which can meet the production requirements of 6005A-T6 state. Therefore, the forward extrusion machine equipped with an online strong wind cooling and quenching device is selected to produce the aluminum alloy blade profile.

[0032] S2. Raise the temperature of the extrusion barrel to 440-460°C. When the embodiment is carried out, the extrusion ...

Abstract

The invention provides a manufacturing process of an aluminum alloy paddle profile. Hot extrusion forming is adopted, wherein an aluminum alloy cast ingot at the temperature of 490-510 DEG C is extruded through an extrusion barrel at the temperature of 440-460 DEG C to form a die at the temperature of 470-480 DEG C. The invention further provides an aluminum alloy paddle manufactured through the method. The manufacturing process is convenient to operate, simple and stable; and the aluminum alloy paddle profile manufactured through the method has excellent mechanical performance, meets various indexes of rotorcraft paddles, and can achieve mass production of the rotorcraft paddles.

Description

technical field [0001] The invention relates to the field of aviation, in particular to an aluminum alloy blade profile and a manufacturing process thereof. Background technique [0002] With the continuous development of aluminum alloy extrusion technology at home and abroad, aluminum alloy hot extrusion profiles are widely used in various industries. In recent years, the domestic aluminum extrusion industry has continuously introduced advanced equipment and technology, especially the localization of aluminum profiles for rail transit, which has greatly improved the domestic aluminum extrusion technology. However, in terms of extrusion production technology of multi-cavity, thin-walled and complex-section industrial profiles, the domestic aluminum extrusion industry is still at the low-end level in the world. Therefore, if we want to be at the forefront of the world's aluminum extrusion technology, we must continue to explore and make breakthroughs in the extrusion molding...
