Embodiment
Technical scheme in the utility model is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
As shown in Figure 1, first the utility model introduces a kind of manufacture method of glass light reflection mirror, and it comprises the steps:
S1., some flat blank materials and some floor base materials are provided.Wherein, the mirror base raw material of use can be ULE, Zerodur, K4, K9 etc.
S2. get two blocks of flat blank materials as the base plate of glass light reflection mirror and top board, get the floor of some floor base materials as glass light reflection mirror, and the faying face of the floor base material as floor is processed.
Wherein, described processing comprises carries out surfaceness process to described floor faying face, to increase the surface area of faying face.Particularly, utilize and there is varigrained emery surfaceness process is carried out to described faying face.Use the emery of W14 ~ W28 to combining surface treatmeX, through the roughness of the faying face of roughening process between 0.8 ~ 1.6.
Further, described processing is also included on floor faying face and offers groove, so that the filling of follow-up glass dust.Particularly, the degree of depth of this groove is less than between 0.05 ~ 0.1mm, and the ratio of the length of described groove and the length of place faying face is less than 0.4.
S3. on corresponding faying face, adopt the mode of clearance-type to coat glass dust, and be pre-installed the floor in step S2 according to the distribution of faying face between the bottom panel and top panel, after being pre-installed, remove unnecessary glass dust.
As shown in Figure 2, described clearance-type mode is coated glass dust A and is carried out in the following manner: the mode of described employing clearance-type is coated glass dust and comprised: coat glass dust in the respective regions in faying face, then, continue to coat glass dust away from the region scribbling glass dust in this faying face, keep, between glass dust region, there is interval, repeat above-mentioned steps to the coating completing glass dust in faying face.So, can effectively reduce in subsequent heat process, due to the STRESS VARIATION that temperature variation causes.
As shown in Figure 3, further, after the mode of above-mentioned employing clearance-type coats glass dust, require that the subtended angle θ at the glass dust edge be coated on faying face is greater than 90 °.
S4. the base plate be pre-installed, top board and floor are sent in low temperature oven and heat, the maximum temperature of heating is kept above glass dust melting temperature 9-11 DEG C, and is incubated at least 10min, after heating, cools, and obtains glass light reflection mirror.
As shown in Figure 4, be the temperature curve of low temperature oven, as seen from the figure, the temperature in low temperature oven is through rising, constant and reduction, and the temperature curve in corresponding low temperature oven is through heating zone a, flat-temperature zone b and cooling annealed zone c.Thus glass dust melts under the condition of heating, and in temperature-fall period gradually in described step S4, in described heating process, heating-up temperature is 380 ~ 450 DEG C, and this heating-up temperature is higher than glass dust melt temperature 9-11 DEG C.So, heating-up temperature far below the softening temperature T1 of the mirror base of catoptron, and a little more than the melt temperature T2 of glass dust, can not have influence on mirror base itself in heating process, glass dust can be made to be melted simultaneously, be convenient to the bonding of base plate, top board and floor.Meanwhile, in stove in heating process, require to heat up comparatively fast, cooling is comparatively slow, to eliminate the unrelieved stress in mirror base.
As shown in Figure 1,5, based on above-mentioned manufacture method, glass light reflection mirror of the present utility model comprises: base plate 10, top board 20 and some floors 30.Wherein, described some floors 30 are arranged between described base plate 10 and top board 20 with laminated form, so that base plate 10 and top board 20 are fixed connection.Described any layer comprises multiple floor 30, and between described floor 30 and base plate 10, between described floor 30 and top board 20, the glass dust got up by melting after coagulation between described some floors 30 bonds.
In above-mentioned embodiment, the surface that described base plate 10, top board 20 and some floors 30 bond mutually is faying face, and described glass dust is coated in the zones of different on described faying face, has spacing between zones of different.And corresponding faying face is uneven surface, to increase the surface area of faying face.In addition, floor faying face also offers groove, and glass dust is loaded in groove.Wherein, the surfaceness of described faying face is 0.8 ~ 1.6.The degree of depth of described groove is less than or equal between 0.05 ~ 0.1mm, and the ratio of the length of described groove and the width of place faying face is less than 0.4.
As shown in Figure 5,6, when the number of plies of floor 30 is two-layer, when floor 30 is for bar shaped, many roots plate 30 regularization in described any layer is arranged, alleged regularization is arranged herein, refers to that many roots plate 30 is arranged between base plate 10 and top board 20 according to certain orientation and arrangement mode.Preferably, many roots plate 30 is parallel to each other, thus multiple floor 30 arranges according to criss-cross fashion.
As shown in Figure 7,8, floor 30 shape can also be triangle or hexagon.Floor 30 shape can also be the shape of the regular distribution such as square.
In sum, glass light reflection mirror lighter weight of the present utility model, reduces launching costs.Meanwhile, avoid the deformation induced by gravity reducing catoptron, and increase the heat radiation area of catoptron, reduce the thermal resistance of thickness direction, reduce catoptron thermograde in a thickness direction, reduce the lens deformation that catoptron causes due to thermograde.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, and the technical scheme in each embodiment also through suitable conjunction, can form other embodiments that it will be appreciated by those skilled in the art that.
