Abstract
The present invention provides a kind of flattening method for aluminium alloy sheet woollen, and the quenched bulge of especially relatively thin 0.50mm or less aluminium alloy sheet woollens loosens smoothing.School thin plate woollen is rolled first with special leveling device, drawn equipment is unidirectionally pre-stretched on straight die again, it further eliminates deformation defects, the flatness of gained thin plate woollen such as woollen bulge, loosening, warpage to significantly improve, the flatness technology requirement needed for sheet metal part manufacture can be met.
Description
Technical field
The present invention relates to a kind of thin plate woollen in aircraft manufacturing field smooth technology, specifically a kind of thin plate woollen bulge,
Flattening method is loosened, the relatively thin quenched bulge of 0.50mm or less aluminium alloy sheet woollens is particularly suitable for, loosens smoothing.
Background technology
Aluminium alloy sheet is that Aircraft Sheet Metal Parts manufacture one of most common material, thin due to rolling and carrying etc.
Plate woollen often will appear the surface quality defects such as bulge, loosening, cannot directly use, be smoothed.
There are two types of flattening methods for aluminium alloy sheet tradition, and one is the smoothing of sheet metal worker craft hammer, this method woollen tables
Face hammer trace is more, influences accessory appearance quality.For relatively thin 0.50mm or less aluminium alloy sheet woollens, can also exist roll over it is thin and
Penetration problem, attacking material mechanical performance itself, cannot be used continuously.Another kind is special leveling device smoothing, this method
For generally thicker aluminium alloy plate, smoothing is reasonable, but for relatively thin 0.50mm or less aluminium alloy sheet woollens, due to
Ability is smoothed beyond equipment, smoothing flatness is still difficult to meet part generally requires thin plate woollen using technology.
Invention content
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of smoothing side for aluminium alloy sheet woollen
Method, the quenched bulge of especially relatively thin 0.50mm or less aluminium alloy sheet woollens loosen smoothing.
School thin plate woollen is rolled first with special leveling device, then drawn equipment is unidirectionally pre-stretched on straight die, into one
Step is eliminated deformation defects, the flatness of gained thin plate woollen such as woollen bulge, loosening, warpage and is significantly improved, and metal plate zero can be met
Flatness technology requirement needed for part manufacture.
This technology advantageous effect of the invention is to be combined with each other two kinds of single smoothing modes, and innovation obtains a kind of new
Thin plate woollen flattening method effectively eliminates the deformation defects such as bulge, loosening, the warpage of thin plate woollen itself, meets metal plate zero
Flatness technology requirement needed for part manufacture.
Attached drawing is described in further detail this application with reference to embodiments；
Description of the drawings
Fig. 1 is to utilize rolling calibration equipment smoothing thin plate woollen schematic diagram
Fig. 2 is to utilize the secondary smoothing thin plate woollen schematic diagram of straight die
Explanation is numbered in figure：1 thin plate woollen, 2 rolling calibration equipments, 3 straight dies, 4 stretchers
Specific implementation mode
Referring to attached drawing, specific steps are implemented as follows：School thin plate woollen 1 is rolled first with special rolling calibration equipment 2, then in straight die
Drawn equipment 4 is unidirectionally pre-stretched thin plate woollen 2 on 3, further eliminates the deformation defects such as woollen bulge, loosening, warpage, gained
The flatness of thin plate woollen significantly improves, and can meet the flatness technology requirement needed for sheet metal part manufacture.It is worth noting that
The pre-stretching straight die 3 is a kind of arch mould of surface bulge, and when pre-stretching, thin plate woollen will be attached to the surface of straight die 3
Simple tension cannot be such that thin plate woollen vacantly singly draws, between pre-stretching amount is the 1%-2% of thin plate woollen length.
Claims (1)
1. a kind of flattening method of aluminium alloy sheet woollen, it is characterised in that：First with leveling device rolling school thin plate woollen, then
Drawn equipment is unidirectionally pre-stretched on straight die, between pre-stretching amount is the 1%-2% of thin plate woollen length, the straight die
It is the arch mould of surface bulge.
