    摘要: A process for bending a glass sheet, in particular one for motor vehicles, with curved areas having small radii of curvature. The bending device used is a bending press having a male type mold and a female type mold. The female type mold consists of at least two mold parts hinged together. After part of the glass sheet heated to bending temperature has been received by the bending press, at least one swivelling mold part of the female type mold is swivelled around the swivel axis, against the male type mold. An adjustable electric motor serves as the drive motor to move the swivelling mold parts. The angular velocity of the swivel action of the swivelling mold parts during the bending process is adjusted as a function of the temperature of the glass sheet and the desired degree of deformation.

    摘要: Glass plates are bent by discharging a glass plate from a suction plate onto a concave circumferential bending ring. Within the furnace (1) the glass plate is gripped by the suction plate (27) and is moved with the latter out of the furnace (1) into a combined bending and tempering station (10) and is discharged there onto the circumferential bending ring (19) located between two blowing boxes (11,13). Immediately following the discharge of the flass plate onto the circumferential bending ring (19), the suction plate (27) moves back to its starting position and the glass plate is tempered in this position.

    摘要: In an apparatus for bending glass panes in a horizontal position, comprising an upper bending mold and a lower frame-shaped mold, the bending force exerted by the bending mold is determined by the self-weight of the bending mold. In order that a uniform pressure shall be exerted by the upper bending mold on the entire periphery of the lower frame-shaped mold, the upper bending is mounted displaceable on its guide rods relative to them in a vertical direction and variable in its angular position relative to the guide rods. To achieve the desired relief of weight of the bending mold, the guide rods are suspended by cables from a frame which can be lowered. On the frame, hydraulic or pneumatic cylinders are disposed, which each exert, via a pulling cable acting on a guide rod, an adjustable force in the opposite direction to the self-weight of the bending mold.

    摘要: A bending furnace for glazings comprises several heating cells, a station for bending by pressing, at least one cooling cell and a system for intermittent transport of glazings. The glazings are laid on bending rings (2), mounted on mobile carriages (3), coupled to one another in a train. The train is pulled by a pulling machine installed at the end of the furnace and outside the latter. The point of application of the pulling machine which moves carriages (3) and the length of the travel of this pulling machine are controlled as a function of the temperature to take into account the variation of length of the train. The precise positioning of the carriage in the pressing station is obtained by a detector (27) joined to pivoting stops (28, 36).

    摘要: In the manufacture of bent or curved car glass plates or panes with more markedly bent areas, the latter are additionally locally heated with acetylene--oxygen, or acetylene--air, flames. An apparatus suitable for this includes a continuous furnace (1) and a bending station (3) with a bending mold (41) positioned above the conveying plane of the glass plates (9), as well as a ring mold (45) which serves as a countermold and a conveying ring and which is located on a movable carriage (44). In the areas of more marked bending below the ring mold (45) are provided burner tubes (42), which are supplied via flexible hoses with the acetylene gas and the combustion air or oxygen. Alternatively, the plates are locally heated in a transition zone (7) located between the furnace and the bending station by a gas burner (8), and thereafter pressed in the bending station by an upper bending mold (14) and a lower ring mold (16).
