Abstract
The invention aims at providing a method for manufacturing a composite hull so as to achieve the effects of high efficiency, high manufacturing quality and low cost. According to the method, a male die matched with a female die is arranged, and firstly, by utilizing the shape of the male die, material layers matched with the female die in shape are manufactured by wrapping the periphery of the male die, and the manufactured material layers are put in the female die; and secondly, a vacuumizing device is used for vacuumizing a hull cavity defined by a vacuum die and the female die, and negative pressure formed in the hull cavity is used for naturally sucking glue into the hull cavity, so that the material layers are combined with one another and solidified. Compared with a manual gluing mode, the glue is distributed in the hull cavity more evenly through the negative pressure sucking mode, surplus glue in the hull cavity is sucked away, glue residues are reduced, and the manufacturing quality of the hull is guaranteed while the weight of the hull is reduced; in addition, the glue which is sucked away can be recycled, so that cost is further lowered. The method can be applied to the field of ships.
Description
Technical field
The invention belongs to ship domain.Be specifically related to the preparation method of hull prepared by a kind of composite.
Background technology
Composite is the feature such as light weight, intensity are high, long service life and more and more broadly being applied owing to having.At ship domain, be especially nearly all adopt composite to prepare hull on unmanned boat.Existing Composite hulls preparation technology is mainly: arrange a ship mould, is then laid on layer by layer on mould by the different multilayer materials of composition hull.Need in this process manually every one-inch of material carefully to be fitted with mould, the time of this at substantial.After completing layer of material laying, need uniform gluing on material.After gluing is complete, re-lay lower layer of material.So repeatedly, until complete the laying of material, finally the whole hull laid is cured process, the demoulding obtains hull.But this process need staff drops into a large amount of energy, and the time of at substantial, operating efficiency is extremely low, and in manual work process, because the technique qualification of staff is different, this also can cause the quality of the hull of making to can not get ensureing.This can not meet existing production requirement.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, aims to provide the Composite hulls preparation method that a kind of efficiency is high, preparation quality good, cost is low.
The technical solution adopted in the present invention is, the method is provided with a former and a formpiston, and former is identical with the shape of the hull that need make with the shape of formpiston, and former can be engaged in outside formpiston, and the method comprises the following steps:
(1) every one deck composite is coated on formpiston and compress outward, cutting makes each layer of material of hull, the material layer made respectively;
(2) the some material layers made to be placed on request successively in former and to compress;
(3) on the outer surface of material layer, lay flow-guiding screen, flow-guiding screen outer surface lays vacuum diaphragm, vacuum diaphragm and former are sealed and matched in the edge of former;
(4) space that vacuum diaphragm and former surround forms hull chamber, arranges gum-injecting port and vacuum orifice respectively in two ends in hull chamber;
(5) at gum-injecting port place, injected rubber hose is inserted in sealing, and at vacuum orifice place, the vacuum tube being connected with vacuum extractor is inserted in sealing, and endoceliac for ship air is taken away by vacuum extractor, and hull chamber forms vacuum, and glue is inhaled in hull chamber by injected rubber hose;
(7) until be full of glue in whole hull chamber, injecting glue completes, and unnecessary glue is extracted out by vacuum extractor;
(7) process is cured to hull, the demoulding, obtains hull.
Such scheme is visible, the present invention arranges a formpiston matched with former, first utilizes the shape of formpiston, in the periphery of formpiston coated go out with the material layer of former matching form, again shaping material layer is placed in former, final curing is shaping, compared with prior art, without the need on former by artificial patch, this greatly increases operating efficiency, staff carries out patch without the need to the energy of at substantial simultaneously, reduces the labour intensity of staff, also reduces cost of labor; Vacuum extractor is adopted to vacuumize the hull chamber that vacuum diaphragm and former surround, the negative pressure formed in hull chamber is utilized naturally to be drawn in hull chamber by glue and material layer to be combined with each other and solidifies, the first, adopt the form of negative-pressure adsorption to make glue enter in hull chamber, glue spreads out evenly; It two is adopt the form of negative-pressure adsorption to make glue can infiltrate every layer of material rapidly, makes between material layer and material layer closelyr superimposed simultaneously, thus improves density and the intensity of hull, ensures the service life of hull; It three is, compared with the mode of artificial gluing, adopt the mode of negative-pressure adsorption that glue is distributed in hull chamber more even, glue unnecessary in hull chamber can be sucked away, decrease unnecessary glue to remain, while alleviating the quality of hull, also assures that the preparation quality of hull, in addition the glue siphoned away can recycle and reuse, and reduce further cost.
A preferred scheme is, in described step (5), also comprise heating steps, in injecting glue process, has heater to heat the endoceliac glue of ship below former and above vacuum diaphragm.
Such scheme is visible, infiltrate in the process of the endoceliac material layer of ship at glue, heater is utilized to be heating and curing to glue wherein, this makes the time of glue curing greatly shorten, and enhances the Hull Strength before the demoulding simultaneously, ensures demoulding quality, greatly increase operating efficiency, indirectly reduce cost, also eliminate staff carries out coating work to every layer of material, reduce the labour intensity of staff.
A preferred scheme is, in described step (2), before being placed in former by the material layer made, needs first bottom former, to lay one deck release cloth.
Such scheme is visible, the setting of release cloth, for follow-up demoulding work provides convenient, improves operating efficiency, also ensure that the quality that hull makes.
Preferred scheme is that the material layer in described step (2) comprises superimposed successively Kev granny rag layer, composite felt layer of cloth and carbon cloth layer further.
Such scheme is visible, and Kev granny rag layer has great intensity and toughness, ensures that hull possesses preferably crashworthiness in actual applications; Compound felt-cloth can strengthen toughness and the intensity of hull equally; The setting of carbon cloth layer then can alleviate the weight of hull significantly; The combination of above-mentioned three kinds of material layers can obtain the structure of a kind of high strength and high rigidity.
Accompanying drawing explanation
Fig. 1 is schematic diagram when former matches with formpiston described in the present invention.
Detailed description of the invention
As shown in Figure 1, the method for the present invention is provided with former 1 and a formpiston 2, and former 1 is identical with the shape of the hull that need make with the shape of formpiston 2. and former 1 can be engaged in outside formpiston 2.Adopt Kev granny rag layer, composite felt layer of cloth and carbon cloth layer to make hull, wherein Kev granny rag layer is positioned on the outer surface of hull.When making, first stack Kev granny rag layer, more superimposed compound carpet veneer and carbon cloth layer.The present invention includes following steps:
(1) every one deck composite is coated on formpiston and compress outward, cutting makes each layer of material of hull, the material layer made respectively;
(2) bottom former, first lay one deck release cloth, the some material layers made to be placed on request successively in former and to compress;
