摘要:
The present invention discloses a device for processing columnar curved tempered glass. The device mainly comprises a glass heating furnace, a glass bending mechanism and a glass tempering mechanism connected sequentially, wherein the arrangement of each supporting roller in the rollers supporting the high temperature flat glass is changed from planar arrangement in space into curved arrangement corresponding to the shape of the glass to be formed, so that the glass bending mechanism enables the glass to suffer bending deformation. Transferring rollers for outputting the formed curved glass in the axial direction of the supporting roller are arranged at the clearance of the rollers of the bending mechanism. In the present invention, bending shaping and tempering of the high temperature flat glass are completed by two stations to break the normal procedure that bending shaping tempering are carried out by one bending appliance intensively, thereby providing a novel technological approach for processing columnar curved tempered glass.

Described herein is a method for the positioning of a glass sheet on a working plane of a glass sheet working machine (1), the method including the steps of: - detection of the position of said glass sheet with respect to said working plane by means of a position detecting electronic system, - provision of a human-machine interface adapted to provide information relative to the position of the glass sheet, - manual displacement of said glass sheet by an operator along said working plane to bring it in a desired position, said manual displacement being assisted via a monitoring of the current position of the glass sheet by means of a position monitoring electronic system, and - signalling to the operator a condition of achievement of the desired position by means of said human-machine interface.

摘要:
Apparatus and a method for forming glass sheets includes a topside transfer platen (44) that releases a heated glass sheet onto a mold supported in an upper position by a mold support frame assembly (62) which then moves the mold vertically downward and rotationally to a lower position for movement horizontally on a track (66) from below the topside transfer platen for continuation of the forming. The apparatus includes an elevator mechanism (84) having a pair of elevators (86) and an associated pair of actuators (88) that are movable different extents in order to provide the vertical and rotational movement of the mold frame support assembly (62).

Apparatus (32) for handling hot glass sheets includes a roll conveyor (14) and a topside transfer platen (18) that overlap to provide assistance in the initial support of heated glass sheets (G) by the topside transfer platen (18) through the use of a vacuum and pressurized air respectively applied to first and second sets of holes (40, 42) in a downwardly facing surface (38) of the topside transfer platen (18).
摘要:
There are a preliminarily bending step for putting heated and softened glass sheet on a preliminarily bending supporting-frame, the glass sheet having an edge portion supported by the preliminarily bending supporting-frame, and for bending the glass sheet into a desired preliminarily bent shape while putting the glass sheet on the preliminarily bending supporting-frame; and a finally bending step for transferring the preliminarily bent glass sheet on a finally bending supporting-frame, the glass sheet having an edge portion supported by the finally bending supporting-frame, and for bending the glass sheet into a final bent shape by pressing the glass sheet against a bending surface of a finally bending mold while putting the glass sheet on the finally bending supporting-frame.
