Description
Technical field
This utility model relates to a kind of light-weight mold for high-precision antenna.
Background technology
The usual layout of antenna for radio astronomy is regional at the dry climate of drought, heatproof, the significant challenge that weather-proof, thermal deformation is electricity antenna material；Simultaneously in order to widen effective frequency range of antenna for radio astronomy, it is generally required to strengthen the size of antenna for radio astronomy.Bring some insoluble problems to the antennas for radio astronomy using conventional steel structure, such as overweight or deterioration in accuracy etc. at above-mentioned 2.
Composite has possessed the high-performance required by Radio Telescope Antenna, low cost, high rigidity, lightweight, Heat stability is good, the over-all properties of the high requirement of surface accuracy.Therefore, the antenna reflector made with it and mould thereof, the most lightweight, and also intensity and dimensional accuracy stability are the highest.Meanwhile, use and spread out frame and be similar to the compartment structure of boats and ships, compared with solid metal, can greatly alleviate the weight of mould while identical supporting surface and bearing capacity are provided.Both advantages are used in combination, are advantage place of the present utility model.
Summary of the invention
This utility model provides a kind of light weight, high intensity, the high-precision light-weight mold for high-precision antenna.
Technical solution adopted in the utility model is:
A kind of light-weight mold for high-precision antenna, it is characterised in that: include die face and for supporting the rigid structure of die face；Described rigid structure includes steelframe and multiple steel diaphragm, and multiple steel diaphragms are vertically fixed on the match profiles of the upper surface of steelframe and the upper surface of multiple steel diaphragm and corresponding die face.
Wherein, described die face includes profile square tube layer, frp layer and the resin bed set gradually from bottom to top；Profile square tube layer is made up of the square tubes of multiple closely tilings successively, and the lower surface of profile square tube layer fixes with the upper surface of multiple steel diaphragms, square tube with steel diaphragm for intersecting setting.
Wherein, described resin for maybe processing plastics for wood.
Compared with prior art, acquired has the beneficial effect that this utility model
1. compared with conventional metals mould, the design of this light-weight mold structure is relatively easy, use steelframe and the method for steel diaphragm combination, the support of die face is provided, ensure that the integral rigidity of mould, and make mold weight significantly be reduced, reduce mould because of deadweight caused by deformation, be advantageously implemented the accuracy of manufacture of mould.
2. this light-weight mold is easily achieved machining and batch micro operations, and cost is relatively low, compared with traditional moulds, its process velocity is fast, and the lead time is short, is advantageously implemented the quick research and development of new product, can response quick to the market demand, be conducive to improving the market competitiveness.

Detailed description of the invention
Below, in conjunction with Fig. 1-Fig. 2, the utility model is described in further detail.
A kind of light-weight mold for high-precision antenna, including die face 1 with for supporting the rigid structure 2 of die face；Described rigid structure 2 includes that steelframe 4 and multiple steel diaphragm 3, multiple steel diaphragms 3 are vertically fixed on the match profiles of the upper surface of steelframe 4 and the upper surface of multiple steel diaphragm 3 and corresponding die face 1.
Embodiment is to offset the error brought due to ground out-of-flatness, uses the method welded the steelframe of each section on the macrotype platform of welding to realize the molding of rigid structure.Rigid structure consist of steelframe and steel diaphragm.Wherein the girder of steelframe, column use the square steel of 100mm × 100mm × 5mm to weld, and diagonal brace uses the square steel welding of 60mm × 60mm × 4mm；Steel diaphragm is 6mm hot rolled steel plate, according to profile being a cross section every 500mm, and is reserved the thickness of fiberglass and Dai Mu by top down, is processed accurately by digital-to-analogue, and same being sequentially welded on the spacing of 500mm is spread out on frame.
The localization method of the short-axis direction of steel diaphragm is, every piece of steel diaphragm all cuts out a triangle polyester fibre breach in bottom, the location square tube that the frame that spreads out welds along centrage fit therewith；The localization method of long axis direction is, by being welded on steelframe by the location angle bar of a determining deviation, steel diaphragm is fitted thereby determine that vertical.Each section, by 15-16 base anchor, regulates the level of steelframe by adjusting bolt.Steelframe carries out heat treatment of annealing after having welded, to eliminate the internal stress that welding process produces.
Described die face includes profile square tube layer 5, frp layer 6 and the resin bed 7 set gradually from bottom to top；Profile square tube layer 5 is made up of the square tubes of multiple closely tilings successively, and the lower surface of profile square tube layer 5 fixes with the upper surface of multiple steel diaphragms 3, square tube with steel diaphragm 3 for intersecting setting.In embodiment, profile square tube is a size of 20mm × 20mm × 1.5mm, and after bending machine bending, dense arrangement is also welded in the profile that steel diaphragm array is provided.First, eliminate rust the square tube in profile, degreasing processes.Filling up the aligned gaps between profile square tube with white carbon afterwards, the resin that can limit frp layer will not flow out along gap, can improve the frp layer adhesive property to little square tube simultaneously.When pasting frp layer, control the thickness of frp layer by controlling the laying number of fiberglass, to reach relevant technology requirement, after completing, carry out corresponding post curing treatment.
In embodiment, resin bed for maybe processing plastics for wood.Maybe will can process plastics for wood and be laid on glass fiber reinforced plastic surface.One layer of white carbon first it is coated with, to strengthen the generation wooden adhesive strength that maybe can process plastics and fiberglass top layer at glass fiber reinforced plastic surface.Pour stirring in blender by maybe can process plastics for wood gum into firming agent proportioning as requested, after color even determines that it is sufficiently mixed, put into and extruder rolls out certain thickness laying under vacuum conditions, be laid on glass fiber reinforced plastic surface.Generation wood maybe can be processed when plastics are laid should the overlap joint of 5mm, to avoid the occurrence of cavity, simultaneously lap-joint should make real, smooth.After completing, carry out corresponding post curing treatment.
Then, use numerical control device that mould type surface layer is carried out machining.Maybe can process after plastics are fully cured for wood, carry out Precision Machining by digital-to-analogue CNC.After completion of processing, repair the tiny holes in profile with white carbon, atomized ash, carry out grinding process, the non-antenna area of resin bed is sprayed resin and high light gel coat realizes the sealing property of mould, complete the manufacture of the light-weight mold for high-precision antenna.
Below the preferred embodiment created this utility model is illustrated, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art it may also be made that modification or the replacement of all equivalents on the premise of this utility model creative spirit, and modification or the replacement of these equivalents are all contained in the application claim limited range.
