Embodiment Construction

[0026] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0027] figure 1 It is a schematic flow chart of the anti-deformation manufacturing method of the aircraft mechanics test pressure ring of the present invention, and the implementation of the present invention will be described in detail below in conjunction with this figure.

[0028] Step 1. Select the appropriate pressure ring material.

[0029] In order to make the deformation of the final manufactured pressure ring small, the material of the pressure ring selected at the beginning is very important. When selecting the material of the pressure ring, a material with high rigidity and strength should be used; in this embodiment, No. 45 steel can be selected. The material of the pressure ring is usually plate type.

[0030] Step 2. Perform initial treatment on the selected pressure ring material.

[0031] The initial treatment of the compression rin...

Abstract

The invention discloses an anti-deformation manufacturing method for a mechanical test compression ring for an aircraft. The method includes the steps: tempering compression ring materials; cutting the compression ring materials to obtain subsections of the compression ring, and connecting the subsections of the compression ring into a whole; performing annealing or artificial aging heat treatment for the whole compression ring; finishing the whole compression ring according to the design size; cutting a welding point of the whole compression ring to obtain a plurality of subsections of the compression ring again; machining cross sections of the subsections of the compression ring according to design requirements; drilling vibrational stress removing holes on the subsections of the compression ring; vibrating the subsections of the compression ring to remove stress; and broaching the subsections of the compression ring after vibrational stress removal to complete the whole manufacturing process. The method is used for reducing residual stress in the process of machining the compression ring and effectively preventing the compression ring from deforming in use, and has the advantages of low machining cost, convenient and visual machining steps, high adaptability and universality and the like.

Description

technical field [0001] The invention relates to a pressure ring for aircraft mechanics test, in particular to a deformation-resistant manufacturing method for the pressure ring. Background technique [0002] At present, there is a problem that the vibrating pressure ring cannot be installed due to radial deformation during use, and the existence of radial deformation is related to its manufacturing method. The traditional manufacturing method is to shape the whole block first, then eliminate the residual stress in the pressure ring through sufficient heat treatment process, and finally cut it. Years of use have shown that this method is not ideal. After the initial cut, the pressure ring is basically not deformed, but after the vibration test, the pressure ring still deforms. This is mainly because the overall processing and re-cutting will cause a large amount of residual stress in the pressure ring. The vibration test is originally a process of stress release. After the s...
