Description
Technical field
This application involves airplane component shot-blast process technical field, particularly a kind of shot-peening fatigue test masking protection side
Method.
Background technology
With the development of airplane design thought, performance of the material in the case where being applicable in load and environmental activity, such as fatigue behaviour
Have become the important evidence of aeroplane structure design, selection and technology assessment.To improve the fatigue strength of material, aircraft rises and falls
Frame, transmission device, the docking site of important feature part, siding etc. will all use shot-blast process.
In recent years, requirement of China's aeroplane structure design to material property is higher and higher, undercarriage, transmission device,
The load-carrying construction part such as docking site, siding of important feature part employ 7055-T7751,2024-T351, Aermet100,
A large amount of novel aluminum alloys such as TC21, unimach, titanium alloy material manufacture.And with the development of blasting technology, ceramic pellet spray
Ball technology is applied to its apparent advantage in aircraft product.The introducing of a large amount of new materials and shot-peening new process, shot-blast process
Parameter is determined to become current urgent problem, and vertical well known, shot-blast process is that metal surface is rushed using moving projectile
It hits and metal surface is made to generate plastic strain layer, the fatigue life of part is made to obtain a kind of process improved or reach certain
The process of shape.It is thus determined that the shot-peening parameter of these new materials and new process, needs largely to carry out fatigue test, and tie
Aircraft target ship class product is closed, fatigue test piece is usually chosen to plate fatigue test piece, and form is as shown in Figure 1.Plate fatigue is tried
When testing part shot-peening, due to the notch sensitivity of seamed edge, to ensure the reliable, effective of testing fatigue test data, the examination of plate fatigue
It tests part should protect seamed edge during shot-peening, due to very small, the traditional guard methods of seamed edge r, such as covers Protection glue band,
It can not implement in technique, it is therefore necessary to a kind of shot-peening fatigue test masking guard method and device are studied, to ensure shot-peening fatigue
Test is smoothed out.
Invention content
The present invention provides a kind of shot-peening fatigue test masking guard method, and the seamed edge of shot-peening fatigue test piece is protected
Shield, and multiple plate fatigue test pieces can be once protected, it determines to provide reliable guarantee for shot-blast process parameter.
Guard method is covered in a kind of shot-peening fatigue test, and including two pieces of identical masking protection boards and cramp frame, masking is protected
The protection notch of multiple hollow outs is provided among backplate, notch shape is consistent with testpieces shape, and appearance and size is retracted than testpieces
1-2mm;Multiple plate fatigue test pieces of required shot-peening are laid on one piece of masking protection board during use, are leaked out by notch
The region of shot-peening is needed on each fatigue test piece, blend compounds band is fixed;Another masking protection board is placed on multiple plates
Above fatigue test piece, the region that shot peening strengthening is needed on fatigue test piece is leaked out again by notch domain, finally with adhesive tape into
Row is fixed;Shot-peening is carried out after being gripped at four angles that two cover protection board with cramp frame, is realized to multiple plates
The masking protection of fatigue test piece seamed edge.
The beneficial effects of the invention are as follows selection this rigidity of structural steel is good, on-deformable material, tried with reference to plate fatigue
Part size is tested, two identical shot-peening fatigue test masking protection boards is processed, the plate fatigue test piece of institute's shot-peening is clipped in
In two pieces of shot-peening fatigue test masking protection boards, realize that the masking to plate fatigue test piece seamed edge is protected.Apparatus structure letter
It is single, easily fabricated and easy to operate, the realistic problem that plate fatigue test piece seamed edge is protected when solving shot-peening testing fatigue.

Specific embodiment
Fig. 1 show plate fatigue test piece 1, and Fig. 2 is masking protection board 2, common 2 up and down;With the arch gripped
Folder 3, totally 4.Protective device is covered in a kind of shot-peening fatigue test, including two pieces of identical masking protection boards 2 and cramp frame 3, is hidden
The protection notch 4 that multiple hollow outs are provided among protection board 2 is covered, 4 shape of notch is consistent with 1 shape of testpieces, and appearance and size is had a competition
It tests part 1 and is retracted 1-2mm.The manufacture material of selection:Thickness is No. 45 steel of 5mm.
Its it is main protection step be as shown in Figure 3, Figure 4:
1st, multiple plate fatigue test pieces 1 of required shot-peening are laid on one piece of masking protection board 2, are leaked by notch 4
Go out on each fatigue test piece 1 to need the region of shot-peening, blend compounds band is fixed;
2nd, another masking protection board 2 is placed on above multiple plate fatigue test pieces 1, is leaked again by 4 domain of notch
Go out on fatigue test piece 1 to need the region of shot peening strengthening, be finally fixed with adhesive tape;
3rd, four angles for covering protection board 2 at two carry out shot-peening after being gripped with cramp frame 3, realize to multiple
The masking protection of 1 seamed edge of plate fatigue test piece.
