Abstract
The invention relates to a forming method of a high-accuracy panel formed by utilizing the compensation of a film and a gluing filler, which comprises the following steps that: (1) a high-accuracy mould is manufactured according to the shape and the specification requirement of a panel of a radiotelescope; (2) a layer of metal film is covered on the mould; (3) the metal film and the mould are jointed favorably, and the back face of the metal film is also coated with glue evenly, wherein the glue comprises a proper filler; (4) a panel matrix which is already processed completely is covered on the metal film coated with the glue; (5) the freedom degree of each side face of the matrix is restricted, and the glue and the filler are evenly filled in a clearance between the film and the panel by utilizing the self weight of the matrix or applying external force; and (6) the operation of demoulding can be carried out after the glue is solidified so as to obtain a high-accuracy panel stuck with the film. According to the forming method of the high-accuracy panel formed by utilizing the compensation of the film and the gluing filler, the aim of high accuracy is achieved by utilizing the fluidity of the glue and the flexibility of the metal film. According to the forming method of the high-accuracy panel formed by utilizing the compensation of the film and the gluing filler, the process of manufacturing a high-accuracy panel of a radiotelescope is simple, the period is short, and the cost is low.
Description
Technical field
The present invention relates to a kind of forming technique of radio telescope panel, be specifically related to a kind of utilize film add gummed filler compensate shaping high-precision surface panel forming method.
Background technology
Millimeter wave and submillimeter wave observation are key areas of astronomy and microwave study.Producing high accuracy panel is one of core technology of millimeter wave, submillimeter wave radio telescope and antenna.
Accurate panel making method at present for millimeter wave or submillimeter wave mainly contains:
1. aluminium casting machine panel machining; The method uses cast aluminium blank to process reflecting curved surface at three coordinate numerical control milling machine.As directly used aluminium plate to process, its panel weight can alleviate but processing capacity strengthens thereupon.
2. honeycomb panel.
3. rigidity reinforcement adds lead-covering structural panel.
4. carbon fiber face sheets.
Mostly cost of manufacture is high for above-mentioned all kinds of panel, and the cycle is long, and some is also difficult to meet the high-precision requirement being applicable to submillimeter wave.
Honeycomb panel of the prior art, rigidity reinforcement add lead-covering structural panel and carbon fiber face sheets, are also to adopt adhesive bonding technique in the technique of these three kinds of methods.But their " splicing " is mainly used as connecting; And the film in the present invention adds glue mainly compensating action.
Main feature of the present invention utilizes the flexibility of the compensatory and metallic film of the mobility of glue, glue inner stuffing to reach high-precision object.Metallic film and matrix are mainly coupled together by structure glue by panel forming, utilize filler contained in colloid and colloid to compensate error contained by matrix surface simultaneously.Film surface is finally made to have very high precision.Meanwhile, the technique that the present invention makes radio telescope high accuracy panel is simple, and the cycle is short, and cost is low.
Summary of the invention
Make the with high costs of radio telescope high accuracy panel to overcome prior art, the cycle is long, precision is undesirable wait not enough, the object of this invention is to provide a kind of utilize film to add to glue together filler compensate shaping high-precision surface panel forming method.The technique that the method makes radio telescope high accuracy panel is simple, and the cycle is short, and cost is low, and can reach higher precision.
The scheme completing foregoing invention task is, a kind of utilize film add gummed filler compensate shaping high-precision surface panel forming method, it is characterized in that, step is as follows,
(1). according to shape and the specification requirement of radio telescope panel, make high-precision mold;
(2). on this mould, cover layer of metal film;
(3). described metal film and described mould are fitted well, and is coated with gluing (glue comprises suitable filler) at its back side equably;
(4). manufactured panel base (containing backrest) is covered on the metal film of coated glue;
(5). the free degree of the constraint each side of matrix, in the space utilizing the weight of matrix itself (adding suitable external force if desired) that glue is filled between film and panel equably;
(6). after gelling is solid, gets final product the demoulding, obtains pad pasting high accuracy panel.
Step (2) in said metal film, aluminium film can be adopted, copper film, stainless steel membrane or other metallic films.
Step (3) in said glue, epoxy resin, polyurethane can be adopted, or milky white adhesive etc.
Step (3) in said suitable filler, metal dust, chalky soil or magnesia powder etc. can be adopted.
In prioritization scheme of the present invention, when (1) described high-precision mold be make according to a part (such as fan-shaped local) for radio telescope panel time, can increase and have following steps:
. by repeat step (2)-(6), obtain the some fan-shaped local of the radio telescope panel of same size;
(8). the some fan-shaped partial splice of the radio telescope panel of several same sizes step (7) obtained becomes a complete radio telescope panel.
The present invention proposes to utilize pad pasting adhering method to make the high accuracy unit panel being applicable to Sub-MM Wave Antenna.Basic thought is by be fitted in by metal film on high-precision mold and to utilize cementing compensation method to make it to become with matrix a complete panel unit.The method can utilize a mould to copy the paraboloidal polylith unit panel of whole circle.
Repeatedly say, basic skills of the present invention first makes high-precision mold, mould covers layer of metal film, film and mould is made to fit good and be coated with gluing (glue comprises suitable filler) at its back side equably, manufactured panel base (containing backrest) is covered on the metal film of coated glue, the free degree of the constraint each side of matrix, the weight of matrix itself is utilized (to add suitable external force if desired, such as, panel base is placed weight, on precision die, applies negative pressure etc.) in space that glue is filled between film and panel equably.After gelling is solid, gets final product the demoulding, obtains pad pasting high accuracy panel, (see photo).The method main feature be utilize metal film have flexibility can with high-precision mold good fit, by the error between the mobility auto-compensation matrix of glue and high-precision mold.The making required precision of this method matrix is not high, only requires to have good stability.By making a high-precision loose tool, the high accuracy panel of whole circle just can be obtained.
