重或いはプレスにより金型形状に倣つて板ガラス
を曲げ成形するようにしている。 Generally, to form bent glass, a plate glass is placed in a mold and placed in a heating furnace maintained at a temperature close to the glass's softening point, and the shape of the glass is shaped into the mold using its own weight or pressing. It is made by bending and forming plate glass.
ところで、自動車のウインドガラスなどにあつ
ては、局部的に深曲げ形状としなければならない
場合があり、この場合深曲げ部分を他の部分と同
等に加熱していたのでは、精度良く曲げることが
できない。 By the way, in the case of automobile window glasses, there are cases where it is necessary to form a deep bend locally, and in this case, if the deep bend part is heated to the same degree as other parts, it will not be possible to bend it accurately. Can not.
そこで従来にあつては第１図に示す如き部分加

スター４，４を係合し、金型３上に載置した板ガ
ラス５を加熱炉１内で搬送するようにしている。 Therefore, in the past, a partial heating device as shown in FIG. 1 has been used. That is, at the bottom of the heating furnace 1, there are a pair of rails 2, 2 in the conveying direction (perpendicular to the paper).
are arranged, and casters 4, 4 of the mold 3 are engaged on these rails 2, 2, so that the plate glass 5 placed on the mold 3 is conveyed within the heating furnace 1.
そして、加熱炉１の天井部に支持ロツド６，６
を挿通固着し、このロツド６の下端部に部分加熱
用のヒータ７を板ガラス５の搬送方向と平行（紙
面垂直方向）に取付けている。 Then, support rods 6, 6 are attached to the ceiling of the heating furnace 1.
A heater 7 for partial heating is attached to the lower end of the rod 6 in parallel to the conveying direction of the glass plate 5 (in a direction perpendicular to the plane of the paper).

図中左右方向）に移動させることができないので
最も部分加熱を必要とする深曲げ部分からヒータ
７が外れることとなり、適切な部分加熱を行なえ
ない。 Such conventional partial heating devices have the disadvantage that, because the partial heating device itself is fixed to the heating furnace, the partial heating device cannot be moved according to the bending shape of the sheet glass. For this reason, it is conceivable to make the support rod 6 freely insertable into and removed from the heating furnace 1 and to fix it at a predetermined position with a pin or the like.
Since the heater 7 cannot be moved in the horizontal direction (in the figure), the heater 7 will come off from the deeply bent portion where local heating is most needed, making it impossible to perform appropriate partial heating.
更に従来の部分加熱装置にあつては、ヒータ７
がガラス搬送の邪魔にならないように、搬送方向
と平行に配設されており、そのため加熱炉内の温
度勾配により、局部加熱の温度も一定でなくなる
という問題もある。 Furthermore, in the case of the conventional partial heating device, the heater 7
are arranged parallel to the conveying direction so as not to interfere with glass conveyance, and there is also the problem that the local heating temperature is not constant due to the temperature gradient within the heating furnace.
