Abstract

The invention relates to a hot bending machine. The hot bending machine comprises a frame, a forming furnace, a hot bending structure and a driving mechanism, wherein the forming furnace is mounted onthe frame; the hot bending structure is arranged in the forming furnace; the hot bending structure comprises a male die and a flexible part configured to be in a tensioned state; the male die is provided with a forming cambered surface; the driving mechanism is used for driving at least one of the flexible part and the male die to move relative to the other, so the flexible part and the male diecan extrude glass, the glass can be bent to be attached to the forming cambered surface, and a cavity is formed in the male die. The hot bending structure is simple in structure, the forming furnace has heat preservation and sealing functions, a desired hot bending temperature and a desired clean environment in the furnace can be guaranteed, and cost reduction, energy consumption reduction, hot bending efficiency improvement and product yield improvement are facilitated.

Description

technical field [0001] The present disclosure relates to the technical field of glass processing equipment, in particular, to a hot bending machine. Background technique [0002] With the ever-changing development needs of industries such as smart phones, smart TVs, and vehicle-mounted new integrated central control display technology, the market demand for curved screen display technology is becoming more and more extensive because of its regular appearance and beautiful shape. The 3D curved glass required for curved screens is the most critical part of curved display technology, and its requirements for production technology are getting higher and higher. [0003] The current hot bending of 3D curved glass is difficult, the method is complicated, and the production efficiency is low. At present, hot bending is generally formed by pressing upper and lower molds, the shape of the mold is complex, and the development cost is relatively high. Contents of the invention [0...
