The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The submarine navigation device pressure shell that the present embodiment provides a kind of composite material to make, this housing is as the erecting stage of the instrument and equipment of underwater detection equipment or other requirements and water isolation, can bear 40MPa(4000m under water) ability of external pressure, and meet lightweight under usage condition, possess certain protecting against shock ability.
In the present embodiment, the physical dimension of pressure shell is required to be: external diameter diameter 760mm, long 1500mm (volume greatly), meet under usage condition, require lightweight; Working environment: extra large underwater work, and the ability that can bear 40MPa external pressure possess certain protecting against shock ability simultaneously.
Based on above-mentioned usage condition, the present embodiment adopts metal and Polymers to make pressure shell, its structure forms as shown in Figure 1, comprises flange 1, vertical ribs 2, support ring 3, frp layer 4, titanium filament winding preparative layer 5, carbon fiber layer 6, protective layer 7 and anticollision ring 8.For meeting above-mentioned operating needs, the present embodiment adopts metallic framework as the ribs 2 of pressure shell, exterior laminate layers is applied with metal filament and other non-metallic materials and is formed integrated member, can reduce like this stress of component inside concentrates, make substantially its uniform internal stress distribute, can guarantee the bearing capacity that it is external again.
The concrete structure of this pressure shell is:
Step 1: make the metallic framework being formed by flange 1, vertical ribs 2 and support ring 3 of high strength 7050 aluminum alloys.
First adopt Forging Technology to make after half-blank the butt flange that is positioned at pressure shell two ends, then adopt process for machining to make finished product.Its object is to improve flange interior tissue, improves its strength and toughness.Guaranteeing under the intensity of flange and the condition of assembly technology simultaneously, by flange design coning structure (its transition face is cambered surface, to avoid stress, concentrate), and add radially cam ring groove with the connecting portion of other materials in flange conical external surface, its effect one is to guarantee, under the condition of fitted position and component strength, can to reduce the weight of member; The 2nd, can strengthen the Joint strenght between flange and other materials.Then two flange coaxials are arranged, wherein the small end face of two flanges is relative.Between two flanges, be uniformly distributed circumferentially a plurality of vertical ribs, for controlling the homogeneity of vertical ribs focal point of stress, adopt riveting process that the two ends of vertical ribs are connected with two flanges respectively.For improving bulk strength, in vertical ribs, equidistantly arrange vertically a plurality of support rings 3, adopt riveting process that described support ring 3 is connected with vertical ribs 2.Adopt riveting process to connect and both can guarantee the intensity of connecting portion, the distortion in the time of can avoiding assembling again.
Step 2: the metallic framework that step 1 has been assembled is arranged in the frock that can rotate, and then lays glass fabric on the outer circumference surface of metallic framework, forms the first frp layer 4.
Be specially: first after flint glass paper hacking being used in the position contacting with glass fabric on metallic framework, with alcohol, clean, then on its outer circumference surface, be wound around 2～3 layers of glass fabric, form the first frp layer 4.In being wound around the process of glass fabric, should be noted: the one, the glass fabric being wound is imposed to the permanent tension force of setting; The 2nd, rotating metallic skeleton equably; The 3rd, when being wound around glass fabric, with the epoxide-resin glue impregnated glass fiber cloth modulating, object is the Joint strenght that strengthens formed the first frp layer 4, improves the rigidity of housing integral body simultaneously.After glass fabric has been wound around, at room temperature solidify 24h, then with Abrasive disc and sand paper, integer is done in the polishing limit, outer circumference surface limit of the first frp layer 4 successively and process.
Step 3: for further improving the pressure resistance of pressure shell, make titanium filament winding preparative layer 5 on the outer circumference surface of formed the first frp layer 4 in step 2.
Be specially: first titanium silk is fixed on the flange of metallic framework one end, its method of attachment is connected to the mode on capstan winch as the cable wire on accommodation ladder winch.Then on titanium silk, apply equably epoxide-resin glue, limit coated side by titanium filament winding on the outer circumference surface of the first frp layer 4.3～4 layers of the permanent tension windings that during coiling, the same glass fabric being wound around of employing is identical, form titanium filament winding preparative layer 5.Titanium filament diameter selected in the present embodiment is in 0.5mm left and right, rigidity and the intensity of member after being so not only convenient to the moulding of member but also can guaranteeing moulding.
Step 4: the outside face at titanium filament winding preparative layer 5 evenly applies one deck epoxide-resin glue, then adopts the operating process of step 2 at 2 layers of glass fabric of outside face coiling of titanium filament winding preparative layer 5, forms the second frp layer 9.Its objective is fixedly titanium filament winding preparative layer 5, prevent from coming off in its working process.
Step 5: adopt three groups of carbon fiber filaments to be directly wound on the second frp layer 9 forming in step 3, make carbon fiber layer 6.
Be specially: one end of three groups of carbon fiber filaments is fixed in respectively on the second frp layer 9, on the outside face of the second frp layer 9, spray one deck resin adhesive liquid, then the pressure shell half-blank limit in limit uniform rotation frock is wound around carbon fiber filament, according to certain rules carbon fiber filament is worked out simultaneously.In being wound around compilation process, after the complete one deck carbon fiber layer in pawnshop, to its outside face sprayed resin glue, then carry out the winding of lower one deck; Until formed carbon fiber layer 6 reaches after it sets thickness, the half-blank of pressure shell is unloaded from frock.
For making the last pressure shell forming there is certain impact resistance when laying or reclaim, guarantee that carbon fiber layer 6 is affixed firmly simultaneously, at the outside face of carbon fiber layer 6, protective layer 7 is set, form thus required pressure shell.The material selection polyamide fat of described protective layer 7 adds glass fibre, wherein the mass ratio of glass fibre/polyamide fat is between 30%～35%, can guarantee the plasticity of protective layer 7 like this, improve its comprehensive mechanical performance, the linear expansion factor of this composite material and aluminum alloy and steel is close simultaneously, it is installed firmly, difficult drop-off.
For further improving the impact resistance of formed pressure shell, on the excircle of protective layer 7, be equidistantly equipped with vertically some anticollision rings 8.The material of described anticollision ring 8 can select sea water resistance, resistance to ozone, rubber that ageing properties is strong to make, and adopts adhesive technology to be sticked on the outside face of protective layer 7, and the pressure shell structure after moulding as depicted in figs. 1 and 2.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
