Two-way bending forming mechanism for glass tempering furnace

Abstract

The invention discloses a two-way bending forming mechanism for a glass tempering furnace. The two-way bending forming mechanism for the glass tempering furnace comprises a frame, a roller table, an air grid and an arc changing mechanism. One end of the arc changing mechanism is hinged to the frame, the other end of the arc changing mechanism is hinged to a translation mechanism of the frame, and the middle portion of the arc changing mechanism is connected to an arc forming mechanism. The arc forming mechanism applies upward action force to the middle portion of the arc changing mechanism to enable the arc changing mechanism to arch upwards during downward bending. The arc forming mechanism applies downward action force to the middle portion of the arc changing mechanism to enable the arc changing mechanism to arch downwards during upward bending. The two-way bending forming mechanism for the glass tempering furnace can be used for achieving the effect that the surface of a film or ink is not in contact with the roller table during two situations of tempered glass inner or outer arc surface bending.

Description

technical field [0001] The invention relates to a forming mechanism for bending toughened glass, in particular, the forming mechanism can bend roller tables in two directions, forward and reverse. Background technique [0002] At present, when making curved tempered glass, there are two forming methods using flexible shaft roller table and hard shaft roller table. Among them, the forming method of flexible shaft bending tempered glass is to bend the flexible shaft roller table perpendicular to the conveying direction, and The molding method of hard shaft bending tempering is to bend the hard shaft roller table in the conveying direction, and use the curved roller table to make curved tempered glass; no matter what kind of molding method is used, when making curved tempered glass, the glass plate is usually forward Bending, that is, the tempered glass is bent into a "︶" shape, and the roller table is supported on the outer arc surface of the glass. For example, the applican...

Problems solved by technology

If the existing equipment is still used to manufacture this kind of glass, the contact surface between the glass and the roller table is just the outer curved surface of the curved tempered glass with a film layer or ink surface, and the roller table will wear the film surface or ink surface, seriously affecting product quality
