The utility model has been compared following advantage with background technology:
1, the utility model technological equipment is simple, only needs one pair of die and a hydraulic press just can produce.
2, the utility model needs factory little because the production equipment amount is few, and working condition is realized easily.
3, the utility model production technology is simple and easy to grasp, and general semiworks just can be produced.
4, the utility model is made parabolic antenna reflector precision height owing to adopt shaped by fluid pressure, and is with low cost, is convenient to produce in batches.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
With reference to Fig. 1, the utility model is made up of reinforcement 1, upper cover plate 2, die 3, sealing ring 5, securing member 6, water intaking valve 7, outlet valve 8, Pressure gauge 9, water pipe 10.The Internal Spherical Surface of the utility model die 3 is made into parabolic shape, if die (3) is for just presenting the parabolic shape antenna reflective face, its diameter dimension 11 is 0,5 to 2 meters, if die 3 is the offset-fed parabolic antenna reflecting surface, its major axis dimension 11 is 0.5 to 2 meter, and embodiment die 3 is made into and just presents the parabolic shape antenna reflective face, and its diameter 11 is 1.5 meters.The base of die 3 is made into the Cylinder type, and it is 1 meter that the Cylinder type is implemented to make diameter, and base keeps flat on the ground during use.40 fastener holes of uniform making are used for fastening usefulness on die 3 flanges.The utility model die 3 is made two kinds of methods, and a kind of method is made into cast-iron blank with die 3, and the pattern with the parabolic antenna reflecting surface is processed into die moulding parabola then.Another kind method adds the die cast-iron blank scrapes epoxy resin, repair a die into die moulding parabola with the parabolic model of antenna, the advantage of this processing method does not need big process equipment processing curve, the moulding of die profile and finishing are carried out on ground, need not go up lathe, do not need to move back and forth, alleviated working strength of workers, technology is simple in addition, and cost is low, high efficiency, the precision that repairs a die height, need not special equipment and place, wide application, so the utility model adopts cast-iron blank to add to scrape epoxy resin and makes die 3.
Install cover plate 2 on die 3 tops, 40 fastener holes of corresponding die 3 uniform making on the upper cover plate 2 garden peripheries, upper cover plate 2 bottoms make groove structure, are used for filling liquid during its effect hydraulic pressure.Garden week be made into inverted trapezoidal structure in the groove outside, tight fit is installed sealing ring 5 in inverted trapezoidal structure, and when upper cover plate 2 clamped with die 3, sealing ring 5 sealed upper cover plate 2 and die 3.Between on the flange of upper cover plate 2 and die 3, lay punching press blank 4, upper cover plate 2 and the interior securing member 6 of installing of die 3 each fastener hole, securing member 6 is used for fastening clamping upper cover plate 2 and die 3, the screw rod of the commercially available M10 of embodiment securing member 6 usefulness, nut are made, the commercially available elastomeric material machining of sealing ring 5 usefulness forms, and the commercially available thick 70 millimeters steel plate materials machining of upper cover plate 2 usefulness forms.When upper cover plate 2 clamped with die 3, also punching press blank 4 and sealing ring 5 were lived in extruding simultaneously, and punching press blank 4 generally adopts the aluminum plate material to make for needing the parabolic antenna plate of moulding.
Welded and installed reinforcement 1 on upper cover plate 2, upper cover plate 2 distortion when reinforcement 1 is prevented hydraulic pressure, the commercially available steel plate materials of embodiment reinforcement 1 usefulness is made.Setting pressure table 9, water pipe 10 respectively in upper cover plate 2 and reinforcement 1 both sides, the conduit of Pressure gauge 9 and water pipe 10 lower end helicitic textures are installed and are communicated with groove structure in the upper cover plate 2 respectively.Install with water intaking valve 7, outlet valve 8 helicitic textures respectively the upper end of water pipe 10, water intaking valve 7, outlet valve 8 are connected with external water pipe 10 respectively, embodiment Pressure gauge 9 adopts commercially available MC type water pressure gauge to make, and turnover water valve 7,8 adopts commercially available general penstock to install and gets final product.
When the utility model parabola antenna reflecting surface is shaped; pressure (hydraulic) water is squeezed in the groove structure 2 of upper cover plate 2 by water intaking valve 7; the water pressure size is put by Pressure gauge 9 and is shown; when water pressure reaches certain pressure; aluminium matter antenna blank 4 pastes die 3 and moulding; open outlet valve 8 and discharge water, loosening fasteners 6, mould unloading obtain needed moulding parabolic antenna reflecting surface.
