Abstract
The utility model discloses a detachable core die, which is need when producing winding engine casing bodies and various composite material storage tanks. A detachable metal framework is arranged on the inner layer of the core die; materials which are rough, soft, capable of absorbing water and being mutually adhered to gypsum slurry materials are wound outside the framework; a gypsum slurry material layer is paved outside the winding materials and fabricated by gypsum powder, cement flour, water and alcohol . The detachable core die resolves the problems that a large die core, particularly a large die core with a joint opening has a comparatively small diameter is difficult to be formed, has low surface quality, poor size stability, and difficult disassembly and the like.
Description
Technical field
The utility model relates to produces winding motor body and the used core of various composite storage tanks, particularly a kind of well behaved detachable core.
Background technology
The winding motor body of Aeronautics and Astronautics, military affairs and civil area and various large-scale composite material storage tanks etc. all will be used core in the process of making.In the process of making, the geometry and the size of profile will guarantee by core in motor body and the storage tank, so core should satisfy following requirement:
A, geometry, dimensional accuracy, dimensional stability and surface quality can satisfy the requirement of profile in the housing;
B, intensity, globality should satisfy the instructions for use of winding process;
C, have good anufacturability and detachability;
D, cost are lower.
At present, in twining motor body production, mainly adopt following three kinds of cores both at home and abroad: the composite core formwork of sand/polyvinyl alcohol core, gypsum core, gypsum surface layer-metallic framework.The composite core formwork of traditional gypsum surface layer-metallic framework is mainly used on the bigger large-scale storage tank container of openings such as cylinder, square tube and circular cone tube, and for the less container of opening, especially the less large-scale mandrel molding and the demoulding of joint opening diameter is all very difficult, dimensional stability and surface quality are all relatively poor, so the composite core formwork of traditional gypsum surface layer-metallic framework is seldom used.
Summary of the invention
The purpose of this utility model is to provide a kind of used detachable core in motor body and the large-scale storage tank production that twines.Thereby solve especially problem such as not high, the poor dimensional stability of less large-scale mandrel molding difficulty, the surface quality of joint opening diameter and form removal difficulty of large-scale core.
The purpose of this utility model is realized by following technical scheme:
A kind of production twined motor body and the used removable dismounting core of various composite storage tank, and its core internal layer is detachable metallic framework; That skeleton is twining outward is coarse, soft, have water imbibition and can with gypsum slip bonding material mutually; Winding material is equipped with outward by land plaster, cement flour, water, alcohol by weight the gypsum feed pulp layer of preparing.
The structure of described detachable metallic framework is (consulting accompanying drawing): the middle part is the mandrel 1 that is provided with step, positioning sleeve 3 is fixed on the mandrel 1 by the step on the mandrel 1 and guiding aluminum pipe 4 and flat key 11 with diaphragm housing ring 10, be with on the guiding aluminum pipe 4 and support aluminum pipe 5, closing end component 6 one ends are stuck on the positioning sleeve 3, the other end links to each other with L type connecting ring 7, joint backing plate 2 before and after front and back positioning sleeve 3 other being provided with, and link to each other with closing end component 6, rod assembly 12 links to each other with connecting ring 8 after passing circular hole on the aluminium dividing plate 13, lay aluminum pipe 9 at core framework aluminum dividing plate 13 upper edge axis directions, aluminum pipe 9 is laid in the semicircle end frame groove of aluminium dividing plate 13, and, link to each other by contiguous block 15 between the aluminium dividing plate 13 with the gap between every adjacent two aluminum pipes 9 of thin aluminum pipe 14 fillings.
The outer material that is twined of described metallic framework is the rope made of hemp or cloth bag or similar material.
Aluminum pipe in the described metallic framework can maybe can be processed into other identical shaped material with sticking plaster or copper rod and replace.
Advantage of the present utility model is:
For twining motor body and various composite storage tank, especially under the less situation of its joint opening diameter, if interior metal skeleton core can not realize freely being disassembled into miscellaneous small parts, will be difficult to take out from internal tank, cause can't finishing the demoulding after the formed product.And the used core skeleton of the utility model can freely be dismantled, thereby can solve especially problem such as not high, the poor dimensional stability of less large-scale mandrel molding difficulty, the surface quality of joint opening diameter and form removal difficulty of large-scale core.
Description of drawings
Accompanying drawing is the structural representation of detachable metallic framework in the utility model.
The specific embodiment
The disclosed structure of above accompanying drawing is the structure of detachable metallic framework among embodiment of the utility model.Among the figure, each parts and label thereof are: mandrel 1; Backing plate 2; Positioning sleeve 3; Guiding aluminum pipe 4; Support aluminum pipe 5; Closing end component 6; L type connecting ring 7; Connecting ring 8; Aluminum pipe 9; Diaphragm housing ring 10; Flat key 11; Rod assembly 12; Aluminium dividing plate 13; Thin aluminum pipe 14; Contiguous block 15.
Below with preparation φ 1200mm fiber twine engine shell body and function core be embodiment the utility model is described in further detail, its enforcement can be undertaken by following operation:
1. core skeleton assembling
Press design drawing assembling core metallic framework.The visible accompanying drawing of structure after the assembling of core skeleton.Wherein, the front connector size is less, and back joint dimension is bigger, is about φ 400mm.
Among the figure, 1 for there being the mandrel of step, behind the products solidifying back joint location cover 3 pulled down, and mandrel can be extracted out from back joint one end;
Among the figure, positioning sleeve 3 is fixed on the mandrel by the step on the mandrel and guiding aluminum pipe 4 and flat key 11 with diaphragm housing ring 10, plays a supportive role;
Among the figure, cover supports aluminum pipe 5 on the guiding aluminum pipe 4, and playing fixedly, aluminium dividing plate 13 prevents the effect that it is vertically collected together;
Among the figure, positioning sleeve 3 was other before and after front and back joint backing plate 2 was located at, and linked to each other with closing end component 6, the interior molding surface size after the forward and backward joint molding of principal security is installed, solidified;
Among the figure, closing end component 6 one ends are stuck on the positioning sleeve 3, link to each other with front and back joint backing plate 2, and the other end links to each other with L type connecting ring 7, plays the fixed seal head assembly jointly;
