Shift forming method for double curved glass tempering procedure

Abstract

The technological scheme of the present invention is to set elevator hidden in the transmission roller conveyor. Heated glass is first raised by the raising elevator from the roller conveyor, mold with notches is then transferred to below the raised glass, and heated glass is transferred by the lowering elevator onto the mold for formation. The glass transferring process has minimized heat loss, and this ensures the glass forming temperature, raises the forming effect and qualified product rate of the hyperboloidal toughened glass. The low manufacture and use cost of the elevator makes it possible to lower the production cost of the hyperboloidal toughened glass.

Description

Technical field [0001] The invention belongs to the technical field of glass tempering molding, and mainly proposes a transfer molding method of hyperboloid glass tempering process. Background technique [0002] The key technology of the existing horizontal roller type hyperboloid tempering furnace is how to transfer the heated glass (650°C-690°C) to the mold for molding, and how to prevent the surface of the glass from being scratched during the transfer process. scratches and scratches, but also to minimize the temperature loss of the glass. At present, the glass tempering molding method used in the horizontal roller type hyperboloid tempering furnace at home and abroad, the more mature glass transfer technology is to use vacuum static pressure (or negative pressure) to lift. (like Figure 1-2 As shown): a vacuum suction cup 1 that is basically the same size as the glass is made of metal materials, and the heated glass 2 (650°C-690°C) is sucked from the transmission rolle...

AI Technical Summary

Problems solved by technology

[0003] 1. The manufacturing cost of the vacuum suction cup is high, and a set of vacuum system (or the use of a compressor to generate negative pressure) is required to cooperate with it, and the cost is relatively high;

[0004] 2. When the vacuum chuck made of metal material absorbs glass, the temperature of the glass will be lost. In addition, the air flow generated in the process of absorbing the glass also accelerates the sharp drop of the glass temperature, which not only seriously affects the forming of the glass effect, and the yield is low;

[0005] 3. This method is okay for producing shallow curved tempered glass, but it is difficult to produce deep curved tempered glass
