Curved glass hot press and forming method

Abstract

The invention discloses a curved glass hot press and a corresponding curved glass forming method. The curved glass hot press is used for performing heating, hot pressing and forming, and cooling on glass in a graphite die to form curved glass. The curved glass hot press comprises a material delivery device, a preheating mechanism, a hot pressing mechanism, a cooling mechanism, a movement mechanism and a material distribution device, and is characterized in that the preheating mechanism is provided with two or more than two groups of preheating assemblies; the graphite die is sequentially heated by the preheating assemblies to reach the hot pressing temperature; the hot pressing mechanism is provided with two or more than two hot pressing assemblies; the glass in the graphite die is sequentially and gradually extruded and formed by the hot pressing assemblies. The curved glass hot press can solve the problems of unenough temperature, low production efficiency due to long preheating time in single working station, poor forming and stability of the curved glass, easiness in oxidizing of parts and components in the equipment under the high-temperature environment, and the like.

Description

technical field [0001] The invention relates to the field of industrial automation, in particular to a curved glass hot press machine for forming flat glass into curved glass by hot pressing. Background technique [0002] The working principle of the existing 3D curved glass machine is usually preheating-forming-cooling. After the first step of preheating is completed, it enters the forming stage. In the forming stage of existing equipment, the glass needs to be completely melted before it can be formed in the mold, so the required temperature is relatively high, and there are often problems such as: insufficient temperature, poor forming stability, and easy to produce defective products; low preheating efficiency, production It takes a lot of time; internal parts are easy to oxidize in high temperature environment and other problems. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a cur...
