  "abstract": "The present invention discloses a method for processing a columnar curved tempered glass. The method specifically comprises the following steps. Bending and tempering of the high temperature flat glass are divided into two stations. Bending is firstly carried out on the high temperature flat glass output by a heating furnace; the columnar extending direction of the curved glass is perpendicular to the direction the glass output from the heating furnace in the bending process, and then the formed curved glass is output to a tempering station in the columnar extending direction thereof to undergo tempering. In the present invention, bending and tempering of the high temperature flat glass are completed by two stations to break the normal procedure that bending and tempering are carried out by a single bending device intensively, thereby providing a novel technological approach for processing the columnar curved tempered glass.",
  "claims": [
    "1. A method for forming a curved tempered glass comprising: bending a previously heated flat glass in a bending station thereby forming a curved glass; tempering the curved glass in a tempering station, wherein the tempering station is separate from the bending station; wherein the flat glass is previously heated in a heating furnace and then is conveyed along a first direction out of the heating furnace and into the bending station; wherein the heated flat glass is subsequently bent in the bending station so that the curved glass extends along a second direction that is perpendicular to the first direction; and wherein the curved glass exits the bending station and enters the tempering station along the second direction; and wherein the heated flat glass is bent in the bending station via a bending mechanism that comprises glass supporting rollers and transferring scroll wheels and wherein each transferring scroll wheel is arranged between two adjacent glass supporting rollers.",
    "2. The method of claim 1, wherein a relative vertical position of each glass supporting roller in the bending mechanism at the bending station is adjustable, and the glass supporting rollers are arranged in a curve corresponding to the shape of the curved glass to be formed.",
    "3. The method according to claim 1, wherein an additional bending station is further interposed between the bending station and the tempering station.",
    "4. The method according to claim 3, wherein a passing-through treatment mode is used to treat the curved glass at the additional bending station, namely the curved glass is subjected to an additional bending treatment while passing through the additional bending station.",
    "5. The method according to claim 1, wherein a passing-through treatment mode is used to treat the curved glass at the tempering station, namely, the curved glass begins tempering during entering the tempering station, and tempering is completed as the curved glass passes through the tempering station.",
    "6. The method according to claim 1, wherein a passing-through treatment mode is used to treat the previously heated flat glass at the bending station, namely, the previously heated flat glass begins bending during entering the glass bending station, and bending is completed when all the previously heated flat glass has entered the bending station."

  "description_excerpt": "The present invention relates to a method used for manufacturing columnar curved tempered glass.\n\nThe columnar curved tempered glass used in reality comprises two kinds, one is the equal arc columnar curved tempered glass as shown in FIG. 1, namely, the columnar curved tempered glass with cross section of circular arc; and the other one is the unequal arc columnar curved tempered glass as shown in FIGS. 2 (a, b, c and d), namely, the columnar curved tempered glass with cross section curve comprising a plurality of arc segments having different curvatures and/or straight segments.\n\nA roller type bending device is usually used for manufacturing the equal arc columnar curved tempered glass. Such bending device comprises a roller type bending mechanism and a chiller cooling mechanism, and the rollers in the rollers bending mechanism are positioned between the upper and lower chillers in the chiller cooling mechanism. The roller type bending mechanism is divided into two kinds according to the operating mode, one is shown in FIG. 3 and FIG. 4, namely, the arrangement of each supporting roller in the rollers supporting 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 as to enable the glass to undergo bending deformation. Such bending mechanism is called as the first mechanism below. FIG. 3 is a schematic diagram showing the bending mechanism before deformation; FIG. 4 is a schematic diagram showing the bending mechanism after deformation.",
