Description
Technical field
The utility model relates to the Wrapping formed mould of a kind of cylindrical shell, belongs to mechanical-moulded technical field.
Background technology
System of Filament Winding Process is under fiber tension and predetermined shaping controlled condition; by the continuous fiber (or cloth, prepegged strands) of dipped resin adhesive liquid according to certain rule be wound into core or in be lining with, then through the goods of solidification, the demoulding, acquisition definite shape.For shaping large scale (shaping length is greater than 5 meters, and diameter of the housing is greater than 2 meters) and two ends with close up cylindrical shell product, the preparation of mould is one of key of product manufacturing always.Mould not only will have good mechanical characteristic, have enough strength and stiffness, can bear in product molding process the various load putting on core, as deadweight, goods weight, and winding tension, solidification internal stress, the cutting force etc. during secondary operations; Also to there is good practicality, namely after urethane cure, core can be broken taking-up from opening part, there is good repeat performance.It is Wrapping formed that current Wrapping formed mould is used for greatly middle-size and small-size cylindrical shell, and forming diameter is generally less than 2 meters.If it is Wrapping formed that existing Wound Dies version is applied to large scale cylindrical shell, gross distortion can be there is greatly and in use very much in mould due to the deficiency of strength and stiffness, own wt, all can bring harmful effect to the follow-up use of forming quality of products and mould like this, and the precision of subsequent product may be had influence on.
Based on this, make subject application.
Utility model content
In order to overcome the above-mentioned defect existing for existing mould, the utility model provides a kind of large-size cylinder body Wrapping formed mould, for large rocket engine muff or other tube structures shaping.
For achieving the above object, the technical scheme taked of the utility model is as follows:
The Wrapping formed mould of a kind of cylindrical shell, be made up of housing, mandrel, supporting mechanism and end socket positioner, described supporting mechanism is provided with multiple, each supporting mechanism is parallel to each other and structure is identical, comprise inner ring, outer shroud and support bar to form, inner ring penetrates in mandrel, and fixes with it with screw; Support bar is distributed between inner ring and outer shroud radially, and support bar adopts the mode of tools for bolts ' pretension to be fixedly connected with latch segment, and its length can regulate, convenient disassembly; Outer shroud and housing are fixed; Housing is fixed by end socket positioner.
Further, as preferably:
Described inner ring is overall structure, is provided with latch segment one.
Described outer shroud is split-type structure, is provided with latch segment two.
Described support bar is uniformly distributed along mandrel is radial, and quantity is not less than 6, and its one end connects the latch segment one of inner ring, and the other end connects the latch segment two of outer shroud.
Described adjacent supports organization establishes has stabiliser bar, for increasing axial rigidity, stabiliser bar has slotted hole, regulates length when being convenient to install.
Described housing is split-type grid hollow structure, is fixed, convenient disassembly by the outer shroud of screw and supporting mechanism.
Described mandrel is notch cuttype tubular structure, and comparatively two ends are thick in centre.
Described end socket positioner is circular flange dish, is used for locating and the housing being connected two ends.
Operation principle of the present utility model is: the Wrapping formed mould of cylindrical shell is made up of housing, mandrel, supporting mechanism and end socket positioner.Before using, be fixed on by supporting mechanism on mandrel, by the condition of support bar in supporting mechanism, Reasonable Orientation, installation outer shell body structure, finally install end socket positioner.Before winding, can adopt disposable frangible, fusible material outside housing, as gypsum, paraffin etc. are for being wound around the demoulding of rear product.During use, by this utility model frame on wrapping machine, wrapping machine support band moving mandrel rotates, and wrapping machine, according to the technical instruction such as laying speed, angle preset, carries out the continuous laying of fiber; After winding, barrel molds together enters autoclave with winding product and carries out cure under pressure; Because the glass manufactured for housing works out the serviceability temperature of cloth and resin higher than the solidification temperature being wound around product, barrel molds still can keep good die shape and intensity, rigidity requirement in autoclave; After product hot-press solidifying, barrel molds mandrel can be extracted out by one end, staff can remove end socket fixture in cylindrical shell outside simultaneously, and rear head closing in place directly can enter inner barrel, remove the inner support mechanism such as supporting mechanism and housing and clear up gypsum, paraffin etc., fast, being separated of product and mould is completed efficiently.
The beneficial effects of the utility model are: achieve the shaping of large rocket combustor outer casing or other tube structures, filled up the blank that domestic large rocket combustor outer casing is Wrapping formed.And the mounting or dismounting of this utility model are convenient, connection is reliable, rigidity is large, be out of shape little, lightweight and cost is low.
The utility model has the advantages that: mould housing is split-type, adopt the manufacture of glass-weave cloth, grid hollow structure, there is the good rigidity of structure and fatigue strength, and saved the manufacturing cost of mould, alleviate mould own wt, for the artificial installation of mould is provided convenience.Increase detachable supporting mechanism and stabiliser bar at mould inside simultaneously, supporting mechanism and stabiliser bar are bolted on the one hand, form wheel hub structure, overall configuration is formed with housing, mandrel, add mold integral rigidity, achieve large length, large-diameter cylinder body Wrapping formed, on the other hand supporting mechanism and stabiliser bar adopt and removably connect, mounting or dismounting are convenient, connection reliably, be out of shape the features such as little and cost is low.
