Description
Technical field
The present invention relates to aircraft manufacturing technology, the particularly shaping of aircraft section bar part, specifically a kind of odd-shaped cross section type
The sagging manufacturing process of material part and shaping dies.
Background technology
Section bar is usually used in shaping various large-scale, complex section, asymmetric, variable curvature three-dimensional section bar part, thus, by extensively
It is applied to the manufacturing industry such as Aero-Space, automobile, building, bridge, elevator and train.Section and sending out before and after edge strip on aircraft, fuselage
The stringer etc. of motivation nacelle, the stress part of this kind of part composition airframe, directly influence the aerodynamic shape of aircraft, because of
And form accuracy requires the highest, such section bar part is coordinated with other sheet metal components by sagging shaping mostly, but some is special-shaped
Cross section section bar sink and shapes difficulty relatively greatly, needs certain moduli lamps structure to reach intended forming effect.
Chinese patent CN203936262U (a kind of hot forming tool sinking for profiles) describes one and relates to
" T " or " L " shape section bar lay back-to-back hot pressing sink shape mould.Its thermoforming mould is by upper die and lower die assembly and is used for
Lathe is fixed the die holder composition of mould, it is possible to meeting "T"-shaped section bar or " L " shape section bar is laid back-to-back, part sink
The demand of molding, can greatly reduce "T"-shaped section bar or " L " shape section bar is laid back-to-back, the workload of part processing, shortening
In the product manufacturing cycle, improve the quality of product.This sagging finishing die has the disadvantages that between upper and lower mould do not have loose piece mistake
Cross, be easy to after forming parts stuck be not easily taken out in lower mold, part handling difficulty；Fastening bolt between upper and lower mould is relatively
Few, easily loosen deformation when suppressing some harder special materials；Disadvantages mentioned above all can cause part production efficiency to reduce, part
The problem that forming quality is poor.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of sink for T-section section bar shape sink mould and
Manufacturing process, this sagging mould can preferably solve abnormal-shaped section bar sink deformed region in forming technique crack,
The defects such as wrinkling, sunken shoulder, and manufacturing process is simple, with low cost, save a large amount of labour force, there is higher economic worth.
The sagging shaping dies of a kind of abnormal-shaped section bar part, this abnormal-shaped section bar part contains horizontal wing plate
With the web of stud shape, described shaping dies contains upper die and lower die, it is characterised in that: the lower surface of described upper mold has and type
The sagging profile of material part wing plate upper surface coupling, described lower mold contains the first half module, the second half module, core and movable mold,
The upper surface of the first half module mates with the wing plate lower surface of section bar part side, the medial wall of the first half module and section bar part web
A sidewall coupling, the upper surface of the second half module mates with the wing plate lower surface of the opposite side of section bar part, the first half module and the
Two half modules are connected by alignment pin, have gap, core to be positioned at the first half module and the second half module between the first half module and the second half module
In the gap of non-sagging part, the side of core has and the profile of section bar another sidewall of part web laminating, core and first
Half module and the second half module secure fit are for positioning the non-sagging part of section bar part, and movable mold is a calibrated bolck structure, lives
In the dynamic gap being embedded in the first half module and the sagging part of the second half module, movable mold has and section bar part web one sidewall is fitted
Profile, movable mold coordinates the sagging part for dynamically T-shaped cross section, location section bar part with the first half module and the second half module,
The active strokes of movable mold and the sagging deep equality of section bar part.
During use, the first half module and the second half module are first fixed with alignment pin, then section bar to be formed is placed in the first half
In the gap of mould and the second half module；Fill with core between the first half module and the second half module section bar of the non-sagging part of section bar
Gap, fixes core and the second half module with alignment pin；Fill section bar by movable mold need to sink first half module and the second half of part
The gap of model material, is supported on the upper surface of movable mold under the web needing depression typing material, passes through pilot hole with alignment pin
Movable mold is located by connecting with the second half module；Upper mold and lower mold matched moulds, make section bar part sink partly and sink with movable mold simultaneously
Shape.
The application has the beneficial effects that: utilizes overall upper mold, split lower mold and core and movable mold, uses alignment pin
The special construction connected, to ensure forming accuracy and the amount of the narrowing requirement of part, movable mold is installed between upper and lower mould and part,
Support for part web surface.Ensure requirement of strength and the conformity of part, improve part forming surface quality, and reduce
Residual stress and artificial school shape timeliness after shaping, be greatly decreased manual school of repairing and measure, simultaneously facilitate handling part, be greatly shortened product
Manufacturing cycle, effectively inhibit abnormal-shaped section bar sink deformed region in forming technique crack, wrinkling, sunken shoulder, it is ensured that
The shape requirement of part and surface quality, solve irregular section bar part and sink and shape a difficult problem.
