ようにしている。 Generally, an apparatus as shown in FIG. 4 is used to manufacture tempered bent glass. That is, the heating furnace 100
The tongs 1 heat the glass plate 101 to near its softening point inside and hold the upper side of the glass plate 101.
02 upwards, the glass plate 101 is placed between the convex die 104 and the concave die 105 of the press bending device 103, and the glass plate 101 is bent by these dies 104 and 105, and then rapidly cooled further upward. The glass plate 101 is placed in the cooling section 106, and the surface of the glass plate 101 is rapidly cooled by cooling air from the cooling nozzles 107 of the quenching section 106, and compressive stress is created on the surface of the glass plate to form a reinforced bent glass. I have to.

止している。 A glass cloth is attached to the pressing surface of the convex mold 104 or the concave mold 105 of the press bending device 103, which is a part of the conventional tempered bent glass manufacturing equipment, that is, the molding surface that comes into contact with the glass plate 101 during pressing. This prevents the glass surface temperature from dropping during pressing.

る。 However, if a glass cloth is used to provide a heat insulating effect, when the mold is removed from the glass plate after molding, the glass plate and the glass cloth will stick together.
Forcibly separating them has the disadvantage of deforming the glass plate. For this reason, it has been proposed in the past to coat the surface of glass cloth with powder of boron nitride (US Pat. No. 4,274,857).
このようにすることである程度、ガラス板とガ

も離型時の変形を防止することができない。 Although this can prevent the glass plate and glass cloth from adhering to each other during separation to some extent, it is not sufficient. In particular, if ceramic paste, which has a lower softening point than glass, is printed on the surface of the glass plate, the glass plate and glass cloth will strongly adhere to each other in this printed area, so be sure to apply the above-mentioned boron nitride powder, etc. However, deformation during mold release cannot be prevented.

To provide a press bending device which minimizes deformation during mold release.

その要旨としている。 In order to achieve such an objective, the present invention is based on the press surface for bending and forming the glass plate, or when a glass cloth is attached to this press surface, a cloth made of high silicate fibers is attached to the glass cloth surface. This is its gist.
以下に本考案の実施の一例を添付図面に基いて
詳述する。 An example of the implementation of the present invention will be described below in detail with reference to the accompanying drawings.

プレス成形するようにしている。 FIG. 1 is a longitudinal sectional side view of the press bending device according to the present invention, in which the press bending device 1 is made up of a convex mold 2 and a concave mold 3, which are movable in the direction toward each other and in the direction in which they are separated by a cylinder device. The convex die 2 is a so-called solid type with a convex press surface 2a at the center, and the concave die 3 has a hollow center and a frame-shaped press part 3a protruding toward the glass plate 4 at the periphery. A glass cloth 5 is placed on the tip of this press part 3a. The peripheral edge of the glass plate 4 suspended by the tongs 6 is press-formed by the press section 3a.

その厚さは0.2mm乃至１mmのものが好ましい。 Then, on the press surface 2a of the convex mold 2, the ratio of high silicic acid fibers, such as silicic acid (SiO 2 ) obtained by acid treatment of glass fibers to elute components other than silicic acid and subsequent heat treatment, is 90% by weight. % or more preferably 96
A cloth 7 made of high silicic acid fiber of 99% to 99% by weight is attached. This cloth 7 is preferably woven in a satin weave, twill weave, or plain weave.
The thickness thereof is preferably 0.2 mm to 1 mm.

付着を更に弱めることができる。 Furthermore, it is also possible to apply a mixed powder of barium sulfate and zinc oxide to the surface of the cloth 7 made of high silicate fibers using a cloth or the like. By doing so, the heat resistance of the surface of the cloth 7 is increased, making it difficult to react with high-temperature glass, and the adhesion between the glass plate 4 and the mold 2 can be further weakened.

弱めることとなる。 In the above process, the glass plate 4 heated in a heating furnace to near its softening point is held between the upper convex mold 2 and the concave mold 3 while being held by the tongs 6, and the glass plate 4 is press-formed into a curved shape between the molds 2 and 3. After that, the molds 2 and 3 are separated from the glass plate 4 and moved further upward to the quenching section where the surface of the glass plate 4 is rapidly cooled to form a strengthened bent glass. In this step, when the glass plate 4 is released from the mold, the cloth 7 made of high silicic acid fibers is interposed between the glass plate 4 and the mold 2, which weakens the adhesion force during mold release.

I would like to add.

極めて効果的である等多大の利点を有する。 As is clear from the above explanation, according to the present invention, when a glass cloth is attached to the press surface of the mold for bending a flat glass plate or to this press surface, the surface of the glass cloth is coated with high silicic acid. By attaching a cloth made of quality fibers, such as fibers containing 90% by weight or more, preferably 96% by weight or more, of silicic acid, the adhesion between the mold and the glass plate can be weakened, and therefore, when the mold is released, This eliminates the disadvantage of deformation of the glass plate. In particular, it is possible to weaken the adhesion force on the parts of the glass plate where the ceramic paste is printed, so it has many advantages, such as being extremely effective when applied to the production of automobile windshields or rear windows.
