Abstract
A panel part aging stress relaxation forming tool solves the problem about positioning of integral panel part aging stress relaxation formed parts of large wings. A forming curved surface for the panel parts is arranged on the body of the forming tool, a positioning pin for the panel parts is arranged at one end of the forming curved surface, and positioning baffles are arranged on the two sides of the forming curved surface.
Description
Technical field
The application relates to the manufacturing technology field of the large wall panel parts of aircraft, particularly lax fixture for forming and the manufacturing process being shaped of the season stress of the large wall panel parts of aircraft in shaping process.
Background technology
It is the stress relaxation effect of utilizing metal that stress relaxation is shaped, and integral panel is bestowed to certain predeformation, makes part elastic strain be converted into plastic deformation after heating.Wallboard residual stress after shaping is little, can promote the stress corrosion resistant ability of material.To requiring artificially aged aluminum alloy part timeliness and being shaped, complete simultaneously.But part still has certain resilience, the finishing of forming jig will be tested and simulate definite.Large planar dimension, small curve, the wallboard that moulding surface structure is complicated, accuracy requirement is high are applicable to this method and are shaped.
Along with improving constantly that present generation aircraft requires, reduce assembly work amount, reduce aircaft configuration weight and become current development trend, part processing is simultaneously towards low stress, small deformation, long-life future development.Large wall panel parts not only meets the demand for development of present generation aircraft, further reduces manufacturing cost, becomes and replaces traditional riveted structure part and the strength member of other sub-assemblies.Large wall panel parts often adopts the lax manufacturing process of season stress to be shaped.The lax shaping of season stress is to utilize the stress relaxation effect of metal in high temperature, and integral panel is bestowed to certain predeformation, and standing a period of time after heating, the stress level of material reduces along with the prolongation of time, makes part elastic strain be converted into plastic deformation.This technique can and be shaped the artificial aging of aluminum alloy part and complete simultaneously, and simultaneously large planar dimension, small curve, the wallboard that accuracy requirement is high are more suitable for this method and are shaped.
And the problem that prior art exists is the large wall panel parts poor rigidity of aircraft, in the lax forming process of season stress, cannot locate, make the shaping qualification rate of part low.
Summary of the invention
Main purpose of the present invention is to provide lax fixture for forming and the manufacturing process being shaped of a kind of wall panel parts season stress, solves the orientation problem of the lax formation of parts of large-scale Integral Wing Panel season stress.
The lax fixture for forming being shaped of a kind of wall panel parts season stress, it is characterized in that the body of this fixture for forming is provided with the profile surface of wall panel parts, the alignment pin that is provided with wall panel parts in a termination of profile surface, is provided with positioning baffle in the both sides of profile surface.
The lax localization method being shaped of wall panel parts season stress, is characterized in that adopting the lax fixture for forming being shaped of wall panel parts season stress described above; First in wall panel parts end machining, go out locator tabs and locating hole; Secondly in the forming face of described fixture for forming, apply dry lubricant, then the locating hole of wall panel parts is socketed on the alignment pin of fixture for forming; After oven dry, carry out lysimetric test and make vacuum bag vacuumizing; Finally fixture for forming and wall panel parts being sent into hot pressing fills with and forms.
Compared with prior art, the present invention has the following advantages:
1. adopt pin-and-hole locate mode location simple, locating hole adapts to the distortion of part in wallboard forming process, can not produce distortional stress, guarantees the precision that wallboard is shaped;
2. adopt non-bolt mode to be fixed, user can be fast and labour-saving load and unload and increase substantially operational convenience.
Below in conjunction with embodiment accompanying drawing to the application be described in further detail 5, accompanying drawing explanation
