摘要： The invention relates to the press bending and tempering of glass sheets, especially for use as glazings in vehicles. When the press bending system is not located in a heated environment such as a furnace, it is important to maintain the glass sheets at a sufficiently high temperature for an adequate degree of temper to be achieved on quenching the sheet. The present invention provides a method of bending and tempering a thin glass sheet comprising pressing the substantially horizontal sheet between moulds having opposed complementary shaping surfaces, at least one of the surfaces being heated, and subsequently quenching the surfaces of the sheet characterised in that the heated shaping surface is maintained at a temperature in the range from 200.degree. C. to 350.degree. C.

摘要： The present invention provides a ring mold for shaping heat-softenable sheet material. The mold includes peripheral wall members enclosing a central cavity having an open upper end. The wall members have an upper sheet shaping surface with a peripheral shape and elevational contour that generally corresponds to a desired peripheral shape and elevational contour of a sheet to be shaped. A first set of slots are positioned along and extend through portions of one of the wall members and a second set of slots are positioned along and extend through portions of an opposing wall member. Each of the slots in the second set is generally horizontally aligned with a corresponding slot in the first set.

摘要： An apparatus for bending a glass sheet in a gravity bending step and in a subsequent press bending step includes a gravity bending mould having a fixed mould portion and an articulated wing portion adjacent to the fixed mould portion, a base on which the fixed mould portion is mounted and a hinged locking arm mounted between the wing portion and the base. The locking arm is movable from an unlocked position in which the wing portion is capable of moving vertically relative to the base to a locked position in which the wing portion is fixed in position relative to the base. A method of bending a glass sheet involves placing a glass sheet on a gravity bending mould having an articulated wing portion and a fixed mould portion, and conveying the mould carrying the glass sheet through a furnace in which the glass is heated to the glass softening point and is bent by gravity until the periphery of the glass sheet is in contact with and conforms to the shape of the upper surface of the gravity bending mould. The wing portion is provided with a locking arm which, during gravity bending, progressively moves from an unlocked position to a locked position at which the wing portion is fixed in a predetermined position corresponding to the desired shape of the glass sheet. The glass sheet is then press bent, while the glass sheet is supported by the gravity bending mould.

摘要： A glass sheet pressing and quenching apparatus including an open center ring having a shape generally corresponding to the shape of the glass sheet and a top support surface extending generally horizontally and conforming to the desired surface contour of the glass sheet. A plurality of flat insulating platelets are removably mounted on the top support surface to define an accurate glass contact surface having low thermal conductivity. The insulating platelets may include a plurality of horizontally inwardly spaced projections with passageways therebetween for communicating quench air therethrough. The ring is mounted on a support frame via a plurality of leveling assemblies, each of which include a mounting plate secured to the ring and adapted to receive a threaded connector having a spherical end portion which is mounted for limited movement within a generally spherical mounting receptacle secured to the support frame. One or more slots are cut into the threads, parallel to the center line of the connector. A spring loaded plunger is mounted in the mounting plate to interfere with the slots in the shaft, thereby providing a detent. The shape of the ring can be modified by controlled adjustment of one or more of the leveling assemblies.

摘要： A heated sheet of glass discharged from a heating furnace is lifted by a ring mold until it is held against a fully continuous lower molding surface of a bent shape of an upper mold. After the sheet of glass is held against the lower molding surface by the ring mold, a vacuum is developed in the upper mold to attract the sheet of glass to the lower molding surface through suction holes defined in the lower molding surface. Thereafter, the ring mold is lowered away from the upper mold to allow the sheet of glass to be bent by the lower molding surface while the sheet of glass is being attracted thereto only under the vacuum developed in the upper mold. The sheet of glass is continuously attracted under the vacuum to the lower molding surface until the sheet of glass is annealed.

摘要： A method of and apparatus for establishing a predetermined thermal profile in a glass sheet immediately prior to press bending outside the heating furnace. The press bending members are provided with arrays of heating elements that are individually or zone regulated to assist in establishing an optimum temperature profile in the glass sheet conducive to proper bending. The temperature profile established in the heated sheet by the arrays of heating elements is coordinated with that established in the furnace and subsequently, modified by heat dissipation as the glass sheet advances to the bending station to achieve the proper bending temperature. The heating elements can also be utilized to create a temperature profile in the glass sheet generally higher than that originally established in the furnace. The sheet can be held in contact with one or both of the heated press members for a brief period of time after bending to slow the cooling rate of the sheet and increase the edge strength of the marginal edge area thereof.

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).
