Problems solved by technology

When the temperature of the two short sides of the glass reaches the high temperature, the middle temperature is too high, resulting in damage to the glass; when the temperature in the middle of the glass is just reached, the two short sides will crack due to insufficient temperature when the glass is formed.
[0004] However, most of the heated glass hot bending pre-pressing devices currently on the market have unstable power and short service life, uneven heating, slow heating and heat dissipation, heating power does not achieve the desired effect, and the defective rate of the produced products is high.
[0005] In summary, the heating and pre-pressing device has the problem of inconvenience in practice, so it is necessary to improve it

Abstract

The invention discloses a multi-stage heating forming prepressing device for hot bending of glass. The device comprises a drive mechanism, a guide mechanism, an upper mold heating assembly and a lower mold heating assembly, wherein the upper mold heating assembly is arranged on the lower side of the guide mechanism; the drive mechanism drives the upper mold heating assembly to be close to or away from the lower mold heating assembly in the guide direction of the guide mechanism; the upper mold heating assembly comprises a first multi-stage heating module; the lower mold heating assembly comprises a second multi-stage heating module. The device is simple in structure, and convenient to dismount, mount, adjust and maintain, and defects caused by uneven heating of glass are reduced.

Description

technical field [0001] The invention relates to the technical field of glass hot-bending forming, in particular to a glass hot-bending multi-stage heating and forming pre-pressing device. Background technique [0002] With the continuous development of science and technology, hot bending glass technology continues to improve. Hot bending glass refers to putting the glass on the mold and heating it to the softening temperature, and then letting the glass bend it by its own weight or external force, and annealing the curved glass. Broken magnets or cracks. [0003] In general, glass is a cuboid with 4 sides and 6 faces. Among them, the heating of the upper and lower sides of the glass is relatively slow, especially the middle of the glass is often heated the slowest, that is, the temperature of the two short sides of the glass after heating is much higher than the temperature of the middle of the glass. When the temperature of the two short sides of the glass is reached, th...
