GLASS SHEETS FORMING DEVICE AND METHOD Russian patent published in 2020 - IPC C03B11/00 C03B11/16 C03B23/03 

FIELD: chemistry.

SUBSTANCE: invention is intended for processing of products, where it is required to mould or bend glass sheet in moulding device, and is improvement of glass processing process. Invention comprises devices for bending and moulding glass sheet and versions of control method. Glass sheet bending device comprises a main frame structure and a first moulding device comprising a first mould and a guide carcass. Guide frame is connected to the first mould. First guide element of the guide frame is directed by the carcass structure so that its lateral movement in any direction is prevented. Second guide element of the guide frame is directed by the carcass structure so that it is laterally movable from the first guide element due to thermal expansion. Device additionally comprises second moulding device containing second shape and frame. Frame supports the second mould so that the second mould is movable in lateral direction relative to the frame. Sensor for detecting the position of one of the forms is also included to determine whether one mould is in a position suitable for docking with the other mould. One of the embodiments of control methods of the glass sheet bending device includes determination of the position of one of the moulds in the heating process and, if necessary, correction of the detected position. Another embodiment envisages shape displacement due to thermal expansion with subsequent adjustment of the mould position before two forms are combined.

EFFECT: higher accuracy of joining moulds improves quality of bent products from glass.
