Problems solved by technology
For ordinary curved surfaces, the arch height and bending axis are easy to find and measure. Due to the deviation of the bending axis of the twisted special-shaped glass, the production and testing of the arch height and bending axis cannot be realized.

Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.
[0022] Drawing requirements:
[0023] See Table 1 for specific parameters of special-shaped curved glass.
[0024] Schematic diagram of dimension marking of special-shaped curved glass Figure 4 shown.
[0025] Table 1 Specific parameters of special-shaped curved glass
[0026]
[0027] The specific operation steps are:
[0028] (1) Make a detection mold with adjustable radius of curvature: such as figure 2 As shown in \3, make a steel pipe structure platform with a length of 4500mm*width of 2200mm*height of 400mm. The platform is composed of several parallel roller tables 1, and there is a screw 2 that can be manually adjusted at an interval of 150MM in the arc direction of both ends ( The adjustment radius range is between 3.7 meters and 50 meters), and the rubber roller table 1 with a diameter of 50MM is used to connect with the to...

The invention relates to an abnormal-shaped curved surface glass detection method, belonging to the glass processing technology field. The abnormal-shaped curved surface glass detection method uses an arc center direction as a symmetric direction of a bending axis of a mould and finds a bending axis of glass according to a drawing through manufacturing a detection mould with an adjustable curvature radius and a curved surface formed by a roller way; a slate pencil is used to mark on two ends of a glass radian; a connection line between the two points is a practical bending axis of the glass; the glass is moved to the mould until the bending axis of the glass is superposed with the bending axis of the mould, and at this time, the mould is a standard mould and the glass is practical glass after bending; when the bending axis of the glass does not change, a contact gap between a lower surface of a glass radian direction and a regulated mould is 0mm according to theoretical calculation; when the glass bending axis is deviated, an uplifting angle can be produced in the radian direction; and thus a distance is produced between the glass radian direction and a rubber roller.
Description
technical field [0001] The invention relates to the technical field of glass processing, in particular to an inspection method for special-shaped curved glass. Background technique [0002] Hot bending glass is also widely used in indoor applications such as display cabinets, shower doors, refrigerators, cabinets, etc. Bent tempered glass is usually used for outdoor purposes, such as glass curtain walls, shop windows, sightseeing elevators, etc. Curved tempered glass is made by heating the original sheet of float glass to the softening temperature to bend the glass into shape, then forming various curved surfaces in a horizontal mold, and then quickly and uniformly cooled by special equipment to form curved tempered glass. The mold is very important in the production of bent tempered glass, because it determines the quality and curvature of the finished hot bent glass. Because the glass has to go through about 720 degrees during the tempering process, the quenching wind pr...
