Description

Technical Field

[0001] The utility model relates to the technical field of heat bending machines, in particular to a curved glass heat bending machine. Background Art

[0002] Hot-bent glass is made by heating and softening flat glass, forming it in a mold, and then annealing it to make curved glass. Hot-bent glass is generally processed in an electric furnace. A continuous hot-bending furnace generally has 5-6 chambers and 11-13 workstations, and a finished product can be produced in about tens of minutes.

[0003] For example, a curved glass bending machine with authorization announcement number "CN218879717U" uses a heating plate and a thermal radiation heater to achieve dual heating of the glass. The heating plate is arranged inside the first fixed seat to achieve heat conduction to the heating plate, so that when the glass is squeezed, it can provide contact heat conduction, ensuring that the glass is heated quickly and evenly, and the bending process is fast. However, when the curved glass bending machine is bending the glass, the equipment directly places the glass on the lower arc mold for bending. When the bending is performed, the position of the glass will be offset due to placement errors, affecting the bending of the glass. At the same time, after the curved glass bending machine has bent the glass, it needs to be placed for a long time to cool the glass before taking it out for collection, which reduces the working efficiency of the equipment.
