A special tempering furnace for the production of curved glass

Abstract

The invention discloses a tempering furnace specially used for producing cambered surface glass, which comprises a feeding device, a heating device and a cambered surface processing device. The heating device comprises a heating box and one side of the supporting rail wheel far away from the supporting bracket is connected with a heating cylinder. The inner wall of both sides of the heating box isfixedly connected with a blast device above the inlet and outlet. The cambered surface processing device comprises an outer box. A blower is fixedly connected to one side of the bottom of the cavityof the supporting box close to the heating device. The connecting block is arranged at one side close to each other and is fixedly connected with an air outlet between the lower cambered surface rollers. The connecting piece is fixedly connected with a ventilation opening between the upper cambered surface rollers. The invention relates to the technical field of tempering furnaces. The tempering furnace specially used for producing cambered surface glass has the advantages that the glass of the device is uniformly heated, the contamination of impurities such as dust and the like is isolated, the product quality is ensured, the cambered surface glass is cooled and bent simultaneously, the rapid change of temperature and shape is reduced, the product yield is ensured, the processing efficiency is improved, and the time is saved.

Description

technical field [0001] The invention relates to the technical field of tempering furnaces, in particular to a tempering furnace specially used for producing curved glass. Background technique [0002] The tempering furnace is a device for producing tempered glass by physical or chemical methods, including physical glass tempering equipment and chemical glass tempering equipment. Physical glass tempering equipment heats flat glass and then rapidly cools it to form compressive stress on the surface of the cooled glass and tensile stress inside the glass, thereby increasing the strength of the glass and making ordinary annealed glass a tempered glass. . Because this tempering method does not change the chemical composition of the glass, it is called physical glass tempering equipment. If divided according to the heating mode characteristics of the equipment, the equipment can be divided into forced convection heating tempering equipment and radiation heating tempering equipme...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a tempering furnace specially used for producing curved glass, which solves the existing processing of curved glass, which is basically processed by heating first, then cooling after bending, not only The processing procedure is cumbersome, and there are no corresponding dust-proof measures, so that the curved glass is not easily damaged during processing and the surface is easily contaminated with impurities, so that the quality of the curved glass cannot be guaranteed, and the processing efficiency is low, which wastes a lot of time.
