DEVICE FOR BREAKING GLASS PLATES BY PRESSING Russian patent published in 2020 - IPC C03B33/03 

FIELD: glass.

SUBSTANCE: disclosed group of inventions relates to a device for breaking glass plates by pressing. Breaking glass plate device comprises a flexible element, on which a glass plate with a cutting line formed on it is placed; support mechanism, on which lower surface of glass plate rests by means of flexible element; a glass plate receiving device having a glass plate receiving surface for receiving a lower surface of the glass plate by means of a flexible element; first moving device for moving the glass plate receiving device; device for breaking glass plate by pressing it along cutting line by pressure on glass plate top surface; and second moving device for pressing device decompression, wherein the first moving device is adapted to move the glass plate receiving device such that during breaking by pressing the glass plate by the pressing breaking device, the receiving surface of the glass plate is located in a position outside the glass plate area, surrounded by the cutting line on the plan view, the second driving device is adapted to move the breaking device by pressing such that during breaking by pressing the glass plate by the pressing device breaking on the upper surface of the glass plate, pressure in the position outside the area of the glass plate can be applied, surrounded by the cutting line on the plan view, in accordance with the movement of the receiving surface of the glass plate, the glass plate receiving device comprises a means of raising and lowering the receiving surface of the glass plate, which when breaking by pressing the glass plate on the cutting line by the pressure device of the breaking device by pressing, raises the receiving surface of the glass plate so as to cause deviation of the glass plate. According to the second embodiment of the glass bending device breaking device, the pressing breaking device is located above the flexible element and has a pressure surface for breaking by pressing along the cutting line of the glass plate with the cutting line formed on it; wherein the glass plate receiving device comprises a means for raising and lowering the receiving surface of the glass plate, which when breaking by pressing the glass plate along the cutting line by the pressure device of the breaking device by pressing raises the receiving surface of the glass plate so as to cause the glass plate to deviate between the cutting line on the glass plate and preset pressure area of glass plate, on which pressure surface should pressure, to pressure on preset pressure area of glass plate, on which pressure surface should pressure.

EFFECT: technical result is exclusion of shearing and obtaining other defects when breaking the glass plate by bending.
