technical field

The utility model relates to a cooling device for the production of bent glass tempering, in particular to a lifting mechanism of the cooling device for the production of bent glass tempering.

Background technique

In the production process of bent glass tempering, since the temperature of the glass is still very high (up to 400-500°C) after tempering and cooling, a process of continuing to cool down to a temperature that can be stored and transported (about 40°C) is required . In the prior art, furnace cooling is often used for further cooling, but since it takes a long time to cool from the tempered temperature to the storage temperature, the production cycle of the entire tempered glass is long and the production efficiency is low. Production costs are higher.

There are also some enterprises that use the axial flow fan to provide compressed air to cool the tempered curved glass. The specific method is to place the axial flow fan on the back side of the unloading table to cool the curved glass.
