Description
Technical Field
The utility model relates to a mold processing field of combined material tubular product, in particular to shaping frock of combined material flange central siphon.
Background
As is well known, with the development of the carbon fiber composite material industry, the carbon fiber composite material has the characteristics of small specific gravity, high specific strength and specific modulus, fatigue resistance and the like, and is increasingly applied to key parts such as transmission shafts and the like. The weight is greatly reduced, the noise is reduced, and the energy loss of a transmission system is reduced. After the flange shaft tube made of the composite material is formed, the problems of high void content, low compactness, poor surface flatness and the like of the flange region often occur, and the use requirement cannot be met.
Disclosure of Invention
In order to overcome the not enough of prior art, the utility model provides a shaping frock of combined material flange central siphon, its convenient operation, simple structure, the product apparent quality is good after the shaping.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a shaping frock of combined material flange central siphon, be equipped with the mandrel, characterized by, three slotted hole blind grooves are processed to mandrel both ends surface hoop evenly distributed, the location external mold of cylinder is fixed in the slotted hole blind groove through positioning bolt, circular location external mold flange has been processed to cylindrical location external mold one end, the cover is equipped with tubulose location centre form on the mandrel of location external mold flange inboard, the both ends processing of location centre form have circular location centre form flange, location centre form and location centre form flange are 1/3 annular structure along the circumferencial direction, location centre form flange is together fixed with location external mold flange through fastening bolt, the cover is equipped with the locking buckle on the tubulose location centre form lateral wall, the interior ring surface cross-section of location centre form is the annular chamber of notch cuttype shape.
The beneficial effects of the utility model are that, its convenient operation, simple structure, the product apparent mass is better after the shaping, and space content is low, and closely knit degree is high, can satisfy operation requirement.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an axial sectional view of the present invention.
In the figure, 1, a core mold, 2, a positioning outer mold, 3, a positioning bolt, 4, a composite flange shaft tube, 5, a positioning inner mold, 6, a locking buckle, 7, a fastening bolt, 8, a positioning outer mold flange, 9, a positioning inner mold flange, 10, an annular cavity and 11, a long round hole blind groove are arranged.
Detailed Description
In the picture, the utility model discloses be equipped with mandrel 1, 1 whole cavity forms of mandrel structure, heat transfer is even when guaranteeing the curing oven heating, the circulation of air is smooth and easy, 1 both ends surface hoop evenly distributed processing of mandrel has three slotted hole blind groove 11, the coefficient of thermal expansion of mandrel 1 and compound material axle is great in product forming process, this project organization can effectively avoid 3 card dead problems of positioning bolt, slotted hole blind groove 11 uses 3 in 1 hoop of mandrel to be suitable, along hoop evenly distributed. A cylindrical positioning external mold 2 is fixed in a long round hole blind slot 11 through a positioning bolt 3, an inner circular ring surface of the positioning external mold 2 is in clearance fit with a core mold 1, a circular positioning external mold flange 8 is processed at one end of the cylindrical positioning external mold 2, a tubular positioning internal mold 5 is sleeved on the core mold 1 at the inner side of the positioning external mold flange 8, circular positioning internal mold flanges 9 are processed at two ends of the positioning internal mold 5, the positioning internal mold 5 and the positioning internal mold flanges 9 are in 1/3 annular structures along the circumferential direction, namely the positioning internal mold 5 and the positioning internal mold flanges 9 are in trisection structures along the circumferential direction, 2 bolt mounting through holes are processed at the outer edge of the end surface of each positioning internal mold flange 9, a fastening bolt 7 penetrates through the bolt mounting through holes to fix the positioning internal mold flange 9 and the positioning external mold flange 8 together, and the uniform stress is ensured after the positioning internal mold 5 of the 3-piece structure is mounted, the locking buckle 6 is sleeved on the outer side wall of the tubular positioning inner die 5, the inner circle ring surface cross section of the positioning inner die 5 is an annular cavity 10 in a step shape, the annular cavity 10 is used for reserving the surface vacuumizing winding thickness of the composite pipe body, the length of the positioning inner die 5 in the axial direction of the core die is larger than 40mm, and the installation dimension of the locking buckle 6 is reserved. The angle of the inboard anchor ring of locking buckle 6 is less than 180, and the interval of bolt locking position is greater than 10mm when guaranteeing two locking buckle cooperations to use, and the back of installation simultaneously, the inboard anchor ring of locking buckle 6 and the area of contact of location centre form 5 are not more than 1/2 of interior anchor ring, guarantee to reserve the displacement volume of bolt locking, and the width of locking buckle uses 20mm-30mm as being suitable, and upper and lower buckle passes through bolt and nut fastening.
When the novel flange compaction device is used, glass fiber or carbon fiber composite prepreg is wound between the positioning outer mold 2 and the positioning inner mold 5 on the core mold 1, the positioning outer mold 2 and the positioning inner mold 5 form a paving cavity of a composite flange, and the flange compaction is realized by screwing the fastening bolt 7; the positioning inner die 5 adopts a three-section combination mode, and because the thickness of the prepreg can not be accurately controlled when the prepreg is laid and pasted, the structural form can effectively ensure that the cavity is completely pasted with the outer surface of the core die 1, the pressure is uniform, and the well-pasted prepreg of the wound glass fiber or carbon fiber composite material forms a composite flange shaft tube after being cured.
