    • It is an object of the present invention to provide a method for bending a glass sheet which can appropriately prevent cloth mark due to suctioning.The present invention is characterized by a method for bending a glass sheet comprising a heating step for heating a glass sheet to soften the glass sheet, and a bending step for bending the heated and softened glass sheet to have a predetermined shape, wherein the bending step comprises a step of pressing the heated and softened glass sheet, whose edges are supported by a supporting frame, against a forming surface of a bending mold opposed to the supporting frame, and a vacuum forming step for providing a negative pressure through a plurality of suction holes formed on the forming surface so that the shape of the pressed glass sheet is bent along the forming surface of the mold, and wherein in the vacuum forming step, the plurality of suction holes are grouped into at least two groups, and the raised negative pressures for the respective groups are lowered at different timings.
    • 本发明的目的是提供一种弯曲玻璃板的方法,该方法可以适当地防止由于抽吸引起的布痕。 本发明的特征在于一种弯曲玻璃板的方法,其包括用于加热玻璃板以加热玻璃板的加热步骤,以及用于将加热软化的玻璃板弯曲成具有预定形状的弯曲步骤,其中弯曲步骤 包括将边缘由支撑框架支撑的加热软化玻璃板压靠在与支撑框架相对的弯曲模具的成形表面上的步骤,以及通过多个抽吸提供负压的真空成型步骤 形成在成形表面上的孔,使得压制玻璃板的形状沿着模具的成形表面弯曲,并且其中在真空成形步骤中,多个吸入孔被分成至少两组,并且升高的负值 各组的压力在不同的时刻降低。

    • A glass bending line for quickly shaping a complex bent glass sheet is provided that includes moving a ring-type female mold, which has a heated glass sheet placed on it, and a full face heated male mold, toward one another. Upon making shaping contact between the glass sheet and the male mold, a vacuum is applied through holes extending through the male mold, for a time sufficient to form the glass sheet to a desired shape. When the glass sheet has been shaped, the vacuum is terminated and pressurized air is connected to the holes to release the bent glass sheet from the male mold. The bent glass sheet is then quickly transported to a quenching station or an annealing station on a continuous conveying device. Hence, the complex bent glass sheet is achieved without the use of a shuttle ring.
    • 提供了一种用于快速成型复杂弯曲玻璃板的玻璃弯曲线,其包括将其上放置有加热的玻璃板的环型阴模和全面加热的阳模彼此移动。 在玻璃板和阳模之间进行成形接触时,通过延伸穿过阳模的孔施加真空足够长的时间以形成所需的形状。 当玻璃板成形时,终止真空并且加压空气连接到孔以将弯曲的玻璃板从阳模释放。 然后将弯曲的玻璃板快速输送到连续输送装置上的淬火站或退火站。 因此,在不使用梭环的情况下实现复合弯曲玻璃板。
