Problems solved by technology
Due to the larger size and thinner wall thickness of the Y-shaped connector, the rigidity of the Y-shaped connector is poor, making it easy to deform during the processing of the Y-shaped connector, which makes the manufacture of the Y-shaped connector more difficult.
[0003] Due to the difficulty in manufacturing the Y-shaped connectors, it has been unable to break through localization, and has been imported from abroad, which makes the cost of the Y-shaped connectors higher.

Abstract
An embodiment of the present invention provides a method for manufacturing an aircraft spherical frame Y-shaped connector. The method includes: obtaining a rod-shaped blank; The arc-shaped structure of the radian is used to obtain a blank; the blank is forged using a preset forging die to obtain a forged piece, wherein the forged piece can be divided into two identical pieces to be processed; The above-mentioned forgings are obtained to obtain two identical workpieces to be processed; the workpieces to be processed are machined to obtain Y-shaped connectors. Using the technical method provided by the embodiment of the present invention can realize the localization of the Y-shaped connector when manufacturing the connector, thereby reducing the cost of the Y-shaped connector.
Description
technical field [0001] The invention relates to the technical field of aircraft manufacturing, in particular to a method for manufacturing an aircraft spherical frame Y-shaped connector. Background technique [0002] The Y-shaped connector of the aircraft spherical frame is usually in the shape of a semi-circular arc with a large outer diameter. For example, the Y-shaped connector of the spherical frame of the C919 aircraft is a one-third arc of the outer diameter of Φ2852mm. Because the size of the Y-shaped connector is large and the wall thickness is thin, the rigidity of the Y-shaped connector is poor, which makes the Y-shaped connector easily deformed during processing, thus making it difficult to manufacture the Y-shaped connector. [0003] Due to the difficulty of manufacturing the Y-shaped connectors, it has been unable to break through localization, and has been imported from abroad, which makes the cost of the Y-shaped connectors relatively high.
