Description
Technical field
The present invention relates to the penalty method processing methods that a kind of forging part single side thin-wall construction beam-like part becomes, and belong to mechanical add
Work processing method field.
Background technique
In field of aerospace, it is often necessary to be machined forging part single side thin-wall construction beam-like part；Such as: part material
Material is 7B04 T6 (MD), and size is 52 mm of 1625mm × 140 mm × δ, and part width is gradually varied to 2mm by 140 mm.
By existing machining scheme, step are as follows:
(1) first roughing plane A, D, C, the unilateral 2mm of surplus；
(2) plane A, B, C, D are processed in place；
(3) shape, web and rib height be in place in part.
After processing, part can distort and buckling deformation, and deflection 5-9mm needs school type.Since deflection is big, school type mistake
Part is easy to produce crackle and scraps in journey, and scrapping failure rate is 30%.
It is therefore desirable to invent a kind of machining process to solve forging part single side thin-wall construction beam-like part warpage and become
Shape situation.
Summary of the invention
The present invention is in order to overcome drawbacks described above, and its purpose is to provide a kind of changes of forging part single side thin-wall construction beam-like part
Penalty method processing method, to solve forging part single side thin-wall construction beam-like part buckling deformation situation.
The present invention to achieve the goals above, the present invention adopts the following technical scheme:
A kind of penalty method processing method that forging part single side thin-wall construction beam-like part becomes:
1., the face roughing part A, C, D, surplus 5mm；
2., shape and web rib in roughing part, 5 mm of surplus；
3., on the basis of the face A, the face semifinishing C, D, surplus 2mm, if the face A deform, allow at the deformation of the face A be added gasket,
Guarantee that compressing anterior diastema is uniformly 1mm；
4., on the basis of the face C, D, the face semifinishing part A, surplus 2mm；
5., shape and web rib in semifinishing part, 2 mm of surplus；
6., on the basis of the face A, finishing the face C, D in place, if the face A deform, allow at the deformation of the face A be added gasket, guarantee pressure
Tight anterior diastema is uniformly 1mm；
7., on the basis of the face C, D, the face precision-machined parts A, B is in place；
8., shape and web rib be in place in precision-machined parts.
Beneficial effects of the present invention:
After being machined the forging part single side thin-wall construction beam-like part using penalty method of the invention, part buckling deformation
Amount control is within 3mm, and part is all qualified after slight school type, ensure that the quality of part well.
The present invention is promoted the use of in the machining of this kind of forging part single side thin-wall construction beam-like part, effectively in our factory
Solves the problems, such as the buckling deformation of part.
