本発明は、ガラス板を加熱後、冷却板の間に挟
み急冷してガラス板を固体接触強化する装置に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for solid contact strengthening a glass plate by heating the glass plate and then rapidly cooling the glass plate between cooling plates.
ガラス板を加熱して、高温になつたガラス板を
急冷し常温になつた状態でガラス板の厚み方向に
残留応力を発生させ、表面層に圧縮応力層を形成
する物理強化（または熱強化）法は広く実施され
ている。このなかでも空気ジエツトにより冷却す
る風冷強化が最も広く実用化されている。 Physical strengthening (or thermal strengthening) involves heating a glass plate, rapidly cooling the heated glass plate, and generating residual stress in the thickness direction of the glass plate when the glass plate reaches room temperature to form a compressive stress layer on the surface layer. The law is widely enforced. Among these, enhanced wind cooling, which uses air jets for cooling, is the most widely used.
物理強化法は、代表的な方法として前述の風冷

の、対象とする固体接触法に区分される。前述の
如く、風冷法は最も広く使用されているが、冷却

又、ガラス板の支持部分の変形を防止するために

速度を大にすることができるが、浸漬冷却時の液
の熱対流・蒸発等により冷却むらが起り易く、又
ガラス板を破損する危険がある等の問題がある。 Physical strengthening methods are typically divided into the aforementioned air cooling method, immersion cooling method in liquid, and solid contact method, which is the subject of the present invention. As mentioned above, the wind cooling method is the most widely used method, but it requires a lot of power from the blower to increase the cooling capacity.
Further, there is a problem in that the glass plate must be prevented from vibrating during heating and air cooling in order to prevent deformation of the supporting portion of the glass plate. Although the immersion method can increase the cooling rate, it tends to cause uneven cooling due to thermal convection, evaporation, etc. of the liquid during immersion cooling, and there is a risk of damaging the glass plate.

法である。一般に、冷却板２内には必要に応じ水
等の冷媒を通し、冷却板２を冷却する。 If a typical example of the solid contact method is shown in Figure 1, 2
In this method, a glass plate 1 is sandwiched between two cooling plates 2 from both sides, an appropriate contact pressure is applied by a liquid pressure cylinder 3, and cooling is performed by thermal conduction between the cooling plate 2 and the glass plate 1. Generally, a coolant such as water is passed through the cooling plate 2 as necessary to cool the cooling plate 2.
通常冷却板２には、銅、グラフアイト等の熱伝

維等よりなる布を緩衝材として冷却板に被せて使
用する。この緩衝材は冷却板の表面の凹凸を吸収
し、ガラス板に歪を生じさせない光学的効果と、
冷却能の均一化効果と、ガラス板表面に傷を発生
することを防止する機械的効果も有している。 Normally, a material with good thermal conductivity such as copper or graphite is used for the cooling plate 2, but if the cooling plate 2 and the glass plate 1 are cooled by bringing them into direct contact, the cooling effect is too strong, and the glass plate Since the board may break or cracks may occur on the surface, a cloth made of glass fiber, metal fiber, etc. is used as a cushioning material by covering the cooling board. This cushioning material absorbs the unevenness of the surface of the cooling plate and has an optical effect that does not cause distortion on the glass plate.
It also has the effect of uniformizing cooling capacity and the mechanical effect of preventing scratches on the glass plate surface.
しかしながら、一般に緩衝材による凹凸の吸収
には限度があり、特にこのガラス板と冷却板の間
に介在させる緩衝材は、冷却能を高くする為に、
厚さを0.1〜0.5mm程度としなければならない。従
つて、この緩衝材による凹凸吸収量は僅かである
ので、冷却板は平坦度を高い精度で仕上げておか
なければならない。冷却板は、一般に機械研削
後、ホーニング、ラツピング等の精密加工により
3/100〜5/100の平坦度に仕上げられている。 However, there is generally a limit to the absorption of unevenness by a cushioning material, and in particular, the cushioning material interposed between the glass plate and the cooling plate is
The thickness must be approximately 0.1 to 0.5 mm. Therefore, since the amount of unevenness absorbed by this cushioning material is small, the flatness of the cooling plate must be finished with high precision. Cooling plates are generally processed by precision processing such as honing and wrapping after mechanical grinding.
It is finished with a flatness of 3/100 to 5/100.
更に、冷却板は、ガラス板を接触冷却している
ときに、ガラス板接触側とその反対側では必ず温
度差が生じ、その温度差による熱反りが発生す
る。この熱反り量は一般に微小量であるが、固体
接触法における本質的な問題であり、その影響は
致命的なものとなる。 Furthermore, when the cooling plate is contact-cooling the glass plate, a temperature difference always occurs between the side in contact with the glass plate and the opposite side, and thermal warping occurs due to the temperature difference. Although this amount of thermal warpage is generally minute, it is an essential problem in the solid contact method, and its influence can be fatal.
例えば、30mm厚の銅板の平板状の冷却板に0.2

A 3 mm thick 300 x 300 mm glass plate was rapidly cooled and strengthened by covering it with a mm thick glass fiber cloth and applying a pressure of 0.5 Kg/cm 2 . The temperature of the glass plate at this time is 680℃ → 400℃
The temperature on the side of the flat cooling plate in contact with the glass plate is 25℃.
→ The temperature on the other side was 65℃, and the temperature on the other side was 54℃. From this, if the temperature difference between both sides of the cooling plate is 11℃, then 0.13
The amount of thermal warpage in mm is calculated. When the stress distribution of the obtained glass plate was measured, it was found to be extremely non-uniform as shown in FIG. In other words, due to thermal warping, the required contact pressure (0.5
Kg/cm 2 ) Not added. The numbers in the figure indicate surface stress values (Kg/cm 2 ). 4 is a hanging hole.

The cooling plate 2 is made of a material with good thermal conductivity such as copper or graphite, and generally has a cavity and is cooled with a cooling fluid such as water. Depending on the shape of the glass plate to be strengthened, such a cooling plate may have a flat surface or a predetermined curved surface on its contact surface with the glass plate. Further, a buffer material is interposed between the cooling plate 2 and the glass plate 1.

材料より選ばれ、例えば鋼板等が使用される。 A reinforcing base material 6 is brought into contact with the side of the cooling plate 2 opposite to the side on which the glass plate 1 is sandwiched, with a heat insulating material layer 5 interposed therebetween, and bolts 7 inserted into the cooling plate 2 allow
A cooling plate 2 is fastened to a reinforcing base material 6.
The illustrated example is an example in which a reinforcing flat plate is used as the base material 6. Note that the substrate is not limited to a flat plate, and base materials of various shapes can be used. The heat insulating material layer 5 is made of a woven fabric, non-woven fabric, or plate made of inorganic fibers such as asbestos and glass fiber, and serves to prevent heat from the cooling plate 2 from being transmitted to the reinforcing flat plate 6. The reinforcing base material 6 is selected from materials with high rigidity, such as a steel plate.

軌条に沿つて移動し得るようになつている。 Another embodiment of the device of the invention is shown in FIG. In this embodiment, the cooling plate 2 is divided vertically and horizontally into nine divided cooling plates, and each divided cooling plate is arranged side by side with a slight gap between them. This makes it possible to reduce warping due to temperature differences in the cooling plate. However, if the gap is set to 1.0 mm or more, the optical quality of the glass plate will deteriorate;
It should be less than 0.5mm, and preferably less than 0.5mm. In FIG. 4, reference numeral 8 denotes a frame on which the cooling plate 2, the heat insulating material layer 5, and the reinforcing base material 6 are mounted, and is movable along the guide rail by a pressing means such as a hydraulic cylinder (not shown).

ある。 Also, instead of dividing the cooling plate, by providing slits, preferably in a grid pattern,
Thermal expansion caused by the difference in temperature rise of the cooling plate can be alleviated. As an example, the width is 0.2 at 10cm pitch.
Good results were obtained when glass plates were strengthened using a cooling plate with slits of 10 mm in diameter and 10 mm in depth arranged in a grid pattern. In this case, the slit width is set to 1.0 mm for the same reason as in the case of the split cooling plate described above.
