　図１は、本実施形態における結晶化ガラス曲板の製造方法を説明するための略図的断面図である。図２は、本実施形態において製造される結晶化ガラス曲板の略図的斜視図である。本実施形態では、図２に示される結晶化ガラス曲板１を製造する方法について説明する。 FIG. 1 is a schematic cross-sectional view for explaining a method for producing a crystallized glass curved plate in the present embodiment. FIG. 2 is a schematic perspective view of a crystallized glass curved plate manufactured in the present embodiment. In the present embodiment, a method for manufacturing the crystallized glass curved plate 1 shown in FIG. 2 will be described.

　結晶化ガラス曲板１は、結晶化ガラスにより構成されている。結晶化ガラス曲板１を構成している結晶化ガラスは、特に限定されない。結晶化ガラス曲板１を構成している結晶化ガラスは、例えば、析出結晶としてα石英固溶体及びβ－スポジュメン固溶体の少なくとも一方を含んでいてもよい。 The crystallized glass curved plate 1 is made of crystallized glass. The crystallized glass constituting the crystallized glass curved plate 1 is not particularly limited. The crystallized glass constituting the crystallized glass curved plate 1 may contain, for example, at least one of α-quartz solid solution and β-spodumene solid solution as precipitated crystals.

　結晶化ガラス曲板１の厚みは、特に限定されないが、例えば、１ｍｍ～１０ｍｍ程度とすることができる。 The thickness of the crystallized glass curved plate 1 is not particularly limited, but can be, for example, about 1 mm to 10 mm.

　結晶化ガラス曲板１は、第１の平板部１ａと、第２の平板部１ｂと、屈曲部１ｃとを有する。屈曲部１ｃは、第１の平板部１ａと第２の平板部１ｂとを接続している。屈曲部１ｃの曲率半径は、５ｍｍ以上であることが好ましく、２０ｍｍ以上であることがより好ましい。なお、屈曲部１ｃが円弧状ではない場合は、屈曲部１ｃの曲率半径は、屈曲部１ｃを円弧状に近似した場合の曲率半径である。 The crystallized glass curved plate 1 has a first flat plate portion 1a, a second flat plate portion 1b, and a bent portion 1c. The bent portion 1c connects the first flat plate portion 1a and the second flat plate portion 1b. The curvature radius of the bent portion 1c is preferably 5 mm or more, and more preferably 20 mm or more. In addition, when the bending part 1c is not circular arc shape, the curvature radius of the bending part 1c is a curvature radius at the time of approximating the bending part 1c to circular arc shape.

　なお、本発明において、結晶化ガラス曲板は、屈曲部を有していればよく、平面部を有している必要は必ずしもない。すなわち、結晶化ガラス曲板は、屈曲部のみにより構成されていてもよい。また、本発明において、「屈曲」には、「湾曲」が含まれるものとする。 In addition, in this invention, the crystallized glass curved plate should just have a bending part, and does not necessarily need to have a plane part. That is, the crystallized glass curved plate may be constituted only by a bent portion. In the present invention, “bending” includes “curving”.

　次に、主として図１を参照しながら、結晶化ガラス曲板１の製造方法について説明する。 Next, a method for manufacturing the crystallized glass curved plate 1 will be described mainly with reference to FIG.

　まず、図１に示される成形装置１０を用意する。成形装置１０は、第１の支持部材１１と第２の支持部材１２と可撓性を有するセラミックペーパー１３とを備えている。本実施形態では、第１の支持部材１１と第２の支持部材１２とが一体に設けられている。このため、第１の支持部材１１と第２の支持部材１２との相対的位置関係が変化しにくい。 First, a molding apparatus 10 shown in FIG. 1 is prepared. The forming apparatus 10 includes a first support member 11, a second support member 12, and a flexible ceramic paper 13. In the present embodiment, the first support member 11 and the second support member 12 are provided integrally. For this reason, the relative positional relationship between the first support member 11 and the second support member 12 is unlikely to change.

　第１の支持部材１１は、板状に設けられている。第１の支持部材１１は、第２の支持部材１２側に向かって斜め下方に延びている。第１の支持部材１１は、第２の支持部材１２側に向かって斜め下方に延びる平面状の第１の支持面１１ａを有する。従って、第１の支持部材１１は、セラミックペーパー１３や後述する結晶性ガラス曲板２０の支持部材としての機能を有している。 The first support member 11 is provided in a plate shape. The first support member 11 extends obliquely downward toward the second support member 12 side. The first support member 11 has a planar first support surface 11a extending obliquely downward toward the second support member 12 side. Accordingly, the first support member 11 has a function as a support member for the ceramic paper 13 and the crystalline glass curved plate 20 described later.

　第２の支持部材１２は、板状に設けられている。第２の支持部材１２は、第１の支持部材１１側に向かって斜め下方に延びている。第２の支持部材１２は、第１の支持部材１１側に向かって斜め下方に延びる平面状の第２の支持面１２ａを有する。従って、第２の支持部材１２は、セラミックペーパー１３の支持部材としての機能を兼ね備えている。第２の支持部材１２の下端部は、第１の支持部材１１の下端部と接続されている。このため、第１の支持面１１ａと第２の支持面１２ａとは、側面視略Ｖ字状となっている。 The second support member 12 is provided in a plate shape. The second support member 12 extends obliquely downward toward the first support member 11 side. The second support member 12 has a planar second support surface 12a extending obliquely downward toward the first support member 11 side. Therefore, the second support member 12 also has a function as a support member of the ceramic paper 13. The lower end portion of the second support member 12 is connected to the lower end portion of the first support member 11. For this reason, the first support surface 11a and the second support surface 12a are substantially V-shaped in a side view.

　なお、第１及び第２の支持部材１１，１２の構成材料は、第１及び第２の支持部材１１，１２に十分に高い耐熱性を付与できるものである限りにおいて特に限定されない。第１及び第２の支持部材１１，１２は、例えば、耐火セラミックスや、耐熱ガラス（耐熱結晶化ガラスなど）、金属などにより構成することができる。 Note that the constituent materials of the first and second support members 11 and 12 are not particularly limited as long as they can impart sufficiently high heat resistance to the first and second support members 11 and 12. The first and second support members 11 and 12 can be made of, for example, refractory ceramics, heat resistant glass (such as heat resistant crystallized glass), metal, or the like.

　セラミックペーパー１３は、第１の支持部材１１と第２の支持部材１２とに支持されている。具体的には、セラミックペーパー１３の一方の端部は、第１の支持部材１１の上端部に固定具１４ａにより固定されており、他方の端部は、第２の支持部材１２の上端部に固定具１４ｂにより固定されている。セラミックペーパー１３のそれ以外の部分は、第１及び第２の支持部材１１，１２には固定されていない。すなわち、セラミックペーパー１３の第１及び第２の支持部材１１，１２に対する固定部（固定具１４ａ、１４ｂ）以外の部分は、第１及び第２の支持部材１１，１２に対して変位可能である。 The ceramic paper 13 is supported by the first support member 11 and the second support member 12. Specifically, one end portion of the ceramic paper 13 is fixed to the upper end portion of the first support member 11 by a fixing tool 14 a, and the other end portion is fixed to the upper end portion of the second support member 12. It is fixed by a fixing tool 14b. Other portions of the ceramic paper 13 are not fixed to the first and second support members 11 and 12. That is, portions of the ceramic paper 13 other than the fixing portions (fixing tools 14 a and 14 b) with respect to the first and second support members 11 and 12 can be displaced with respect to the first and second support members 11 and 12. .

　セラミックペーパー１３は、第１の支持面１１ａにより支持されている平板状の第１の部分１３ａと、第２の支持面１２ａにより支持されている平板状の第２の部分１３ｂと、第１の部分１３ａと第２の部分１３ｂとを接続している屈曲部１３ｃとを有する。屈曲部１３ｃは、第１及び第２の支持部材１１，１２と離間している。このため、屈曲部１３ｃは、変形可能である。 The ceramic paper 13 includes a flat plate-like first portion 13a supported by the first support surface 11a, a flat plate-like second portion 13b supported by the second support surface 12a, and a first It has the bending part 13c which has connected the part 13a and the 2nd part 13b. The bent portion 13 c is separated from the first and second support members 11 and 12. For this reason, the bending part 13c is deformable.

　なお、セラミックペーパー１３は、例えば、アルミナなどにより構成することができる。セラミックペーパー１３の厚みは、例えば、０．５～５ｍｍ程度とすることができる。セラミックペーパー１３が薄すぎるとセラミックペーパー１３の強度が低くなりすぎる場合がある。一方、セラミックペーパー１３が厚すぎると、セラミックペーパー１３の可撓性が低くなりすぎる場合がある。 The ceramic paper 13 can be made of alumina, for example. The thickness of the ceramic paper 13 can be about 0.5 to 5 mm, for example. If the ceramic paper 13 is too thin, the strength of the ceramic paper 13 may be too low. On the other hand, if the ceramic paper 13 is too thick, the flexibility of the ceramic paper 13 may be too low.

　次に、セラミックペーパー１３の上に、結晶化ガラス曲板１の母材である結晶性ガラス曲板２０を載置する。結晶性ガラス曲板２０は、結晶化ガラス曲板１と実質的に同様の形状を有することが好ましい。すなわち、結晶性ガラス曲板２０は、第１の平板部２１と、第２の平板部２２と、第１の平板部２１と第２の平板部２２とを接続している屈曲部２３とを有することが好ましい。結晶性ガラス曲板２０は、第１の平板部２１が第１の部分１３ａと接触し、第２の平板部２２が第２の部分１３ｂと接触し、屈曲部２３が屈曲部１３ｃと接触するようにセラミックペーパー１３の上に載置される。 Next, the crystalline glass curved plate 20 which is the base material of the crystallized glass curved plate 1 is placed on the ceramic paper 13. The crystalline glass curved plate 20 preferably has substantially the same shape as the crystallized glass curved plate 1. That is, the crystalline glass curved plate 20 includes a first flat plate portion 21, a second flat plate portion 22, and a bent portion 23 that connects the first flat plate portion 21 and the second flat plate portion 22. It is preferable to have. In the crystalline glass curved plate 20, the first flat plate portion 21 is in contact with the first portion 13a, the second flat plate portion 22 is in contact with the second portion 13b, and the bent portion 23 is in contact with the bent portion 13c. Is placed on the ceramic paper 13.

　次に、セラミックペーパー１３の上に載置した結晶性ガラス曲板２０を加熱して結晶化させることにより結晶化ガラス曲板１を作製する。熱処理の温度や時間は、結晶化ガラス曲板１の主結晶などに応じて適宜設定することができる。熱処理温度は、例えば、７００℃～９００℃程度とすることができる。熱処理時間（最高温度で保持する時間）は、２時間～６時間程度とすることができる。 Next, the crystallized glass curved plate 1 is produced by heating and crystallizing the crystalline glass curved plate 20 placed on the ceramic paper 13. The temperature and time of the heat treatment can be appropriately set according to the main crystal of the crystallized glass curved plate 1. The heat treatment temperature can be about 700 ° C. to 900 ° C., for example. The heat treatment time (time for holding at the maximum temperature) can be about 2 to 6 hours.

　ところで、結晶性ガラス曲板２０は、結晶化工程において変形する。この変形により結晶性ガラス曲板２０の屈曲部２３の曲率半径が小さくなる。そのため、図３に示すように、セラミックペーパー１１３の全体を支持部材（第１及び第２の支持部材１１１，１１２）により支持し、結晶性ガラス曲板１２０の屈曲部１２３と、セラミックペーパー１１３とを離間させた状態で結晶化させた場合、結晶性ガラス曲板１２０の屈曲部１２３が変形し、屈曲部１２３が支持部材とセラミックペーパー１１３を介して接触し、自重が結晶性ガラス曲板の屈曲部１２３と支持部材との接触部にセラミックペーパー１１３を介して加わる。その結果、結晶性ガラス曲板１２０の屈曲部１２３に大きな接圧力が加わる。よって、結晶性ガラス曲板１２０の屈曲部１２３にセラミックペーパー１１３の表面形状が転写されやすくなる。その結果、得られる結晶化ガラス曲板の屈曲部の表面性状が悪くなる場合がある。 By the way, the crystalline glass curved plate 20 is deformed in the crystallization process. This deformation reduces the radius of curvature of the bent portion 23 of the crystalline glass curved plate 20. Therefore, as shown in FIG. 3, the entire ceramic paper 113 is supported by the support members (first and second support members 111 and 112), the bent portion 123 of the crystalline glass curved plate 120, the ceramic paper 113, , The bent portion 123 of the crystalline glass curved plate 120 is deformed, the bent portion 123 comes into contact with the support member via the ceramic paper 113, and its own weight is the crystalline glass curved plate. The contact portion between the bent portion 123 and the support member is added via the ceramic paper 113. As a result, a large contact pressure is applied to the bent portion 123 of the crystalline glass curved plate 120. Therefore, the surface shape of the ceramic paper 113 is easily transferred to the bent portion 123 of the crystalline glass curved plate 120. As a result, the surface property of the bent portion of the obtained crystallized glass curved plate may be deteriorated.

　これに鑑み、例えば、図４に示されるように、セラミックペーパー１１３から離れる屈曲部１２３の下方に予め支持台１３０を設けておくことも考えられる。しかしながら、この場合であっても、結晶性ガラス曲板１２０の自重を、結晶性ガラス曲板１２０全体で支持することができないため、一部分に自重が集中し、得られる結晶化ガラス曲板の表面性状が悪くなる場合がある。 In view of this, for example, as shown in FIG. 4, it is conceivable to provide a support 130 in advance below the bent portion 123 that is separated from the ceramic paper 113. However, even in this case, since the weight of the crystalline glass curved plate 120 cannot be supported by the entire crystalline glass curved plate 120, the weight of the crystalline glass curved plate 120 is concentrated on a part, and the surface of the obtained crystallized glass curved plate is obtained. Properties may deteriorate.

　それに対して本実施形態では、セラミックペーパー１３の屈曲部１３ｃを支持部材１１，１２から離間させておく。セラミックペーパー１３が結晶性ガラス曲板２０の屈曲部２３を支えるため、結晶化工程において結晶性ガラス曲板２０が過度に変形し、ガラス曲板２０の屈曲部２３の曲率半径が小さくなり過ぎることを抑制することができる。また、セラミックペーパー１３の屈曲部１３ｃが支持部材１１，１２から離間しているため、セラミックペーパー１３にガラス曲板２０の自重が加わったとしても、ガラス曲板２０の屈曲部２３とセラミックペーパー１３との接圧力が、ガラス曲板２０がセラミックペーパー１３及び支持部材１１，１２の両方に接した時の接圧力よりも小さく、屈曲部２３にセラミックペーパー１３の表面形状が転写されにくい。その結果、得られる結晶化ガラス曲板の屈曲部の表面性状が良好となる。 In contrast, in this embodiment, the bent portion 13c of the ceramic paper 13 is separated from the support members 11 and 12. Since the ceramic paper 13 supports the bent portion 23 of the crystalline glass curved plate 20, the crystalline glass curved plate 20 is excessively deformed in the crystallization process, and the curvature radius of the bent portion 23 of the glass curved plate 20 becomes too small. Can be suppressed. Further, since the bent portion 13c of the ceramic paper 13 is separated from the support members 11 and 12, even if the weight of the glass curved plate 20 is added to the ceramic paper 13, the bent portion 23 of the glass bent plate 20 and the ceramic paper 13 are added. Is smaller than the contact pressure when the glass curved plate 20 is in contact with both the ceramic paper 13 and the support members 11 and 12, and the surface shape of the ceramic paper 13 is not easily transferred to the bent portion 23. As a result, the surface property of the bent portion of the obtained crystallized glass curved plate is improved.

　優れた表面性状を有する結晶化ガラス曲板１を製造し得る本実施形態の技術は、屈曲部２３の曲率半径が５ｍｍ以上、さらには２０ｍｍ以上であり、屈曲部２３がセラミックペーパー１３から離れやすい場合に特に有効である。すなわち、優れた表面性状を有する結晶化ガラス曲板１を製造し得る本実施形態の技術は、屈曲部１ｃの曲率半径が５ｍｍ以上、さらには２０ｍｍ以上である結晶化ガラス曲板１の製造に特に有効である。 In the technique of the present embodiment that can produce the crystallized glass curved plate 1 having excellent surface properties, the curvature radius of the bent portion 23 is 5 mm or more, further 20 mm or more, and the bent portion 23 is easily separated from the ceramic paper 13. It is especially effective in cases. That is, the technique of the present embodiment capable of manufacturing the crystallized glass curved plate 1 having excellent surface properties is used for manufacturing the crystallized glass curved plate 1 in which the curvature radius of the bent portion 1c is 5 mm or more, and further 20 mm or more. It is particularly effective.

　なお、屈曲部１３ｃが支持されていない本実施形態においては、セラミックペーパー１３の強度が高いことが好ましい。従って、セラミックペーパー１３の厚みは、０．５ｍｍ以上であることが好ましく、１．０ｍｍ以上であることがより好ましい。但し、セラミックペーパー１３が厚すぎると、屈曲部１３ｃの形状を有するセラミックペーパー１３を作製する場合に、セラミックペーパーを曲げる必要があるので、セラミックペーパー１３の内側表面にシワが生じやすい。このシワが結晶性ガラス曲板の軟化時に転写し、結晶化ガラス曲板の外観が損なわれる場合がある。従って、セラミックペーパー１３の厚みは、５．０ｍｍ以下であることが好ましく、２．０ｍｍ以下であることがより好ましい。 In addition, in this embodiment in which the bending part 13c is not supported, it is preferable that the strength of the ceramic paper 13 is high. Therefore, the thickness of the ceramic paper 13 is preferably 0.5 mm or more, and more preferably 1.0 mm or more. However, if the ceramic paper 13 is too thick, it is necessary to bend the ceramic paper 13 when producing the ceramic paper 13 having the shape of the bent portion 13 c, so that wrinkles are likely to occur on the inner surface of the ceramic paper 13. The wrinkles are transferred when the crystalline glass curved plate is softened, and the appearance of the crystallized glass curved plate may be impaired. Therefore, the thickness of the ceramic paper 13 is preferably 5.0 mm or less, and more preferably 2.0 mm or less.

　（変形例）
　上記実施形態では、第１の支持部材１１と第２の支持部材１２とが一体に設けられている例について説明した。但し、本発明は、この構成に限定されない。例えば、図５に示されるように、第１の支持部材１１と第２の支持部材１２は一体に設けられていていなくてもよい。図５に示す例では、屈曲部１３ｃの下方には、第１及び第２の支持部材１１，１２が設けられていない。 (Modification)
In the above embodiment, the example in which the first support member 11 and the second support member 12 are provided integrally has been described. However, the present invention is not limited to this configuration. For example, as FIG. 5 shows, the 1st supporting member 11 and the 2nd supporting member 12 do not need to be provided integrally. In the example shown in FIG. 5, the first and second support members 11 and 12 are not provided below the bent portion 13c.

　また、図６に示されるように、支持部材１１，１２は、支持面を有しておらず、セラミックペーパー１３の結晶性ガラス曲板２０の下に位置する部分の全体が支持されていなくてもよい。例えば、全体が屈曲部である結晶化ガラス曲板を製造する際に有効である。 Further, as shown in FIG. 6, the support members 11 and 12 do not have a support surface, and the entire portion of the ceramic paper 13 located under the crystalline glass curved plate 20 is not supported. Also good. For example, it is effective when manufacturing a crystallized glass curved plate that is entirely bent.
