Cold-joining process for glass kettle

Technical Field

The invention relates to the field of glass product production, in particular to a cold joint process for a glass kettle.

Background

Glass is a common material, and glass products also account for a large proportion in daily life of people, wherein the wine distributor is a common glass product and is mainly used for containing wine and distributing the wine into a plurality of wineglasses. In order to facilitate the use, the wine distributor comprises a handle besides a kettle body, the handle made of glass cannot be formed with the kettle body at the same time, the handle is usually formed and then welded on the kettle body in the traditional method, but the temperature of the kettle body is lower during welding due to the fact that the kettle body is formed, cracks are prevented from appearing on the kettle body due to the fact that the temperature of the kettle body is lower than that of the handle in most degrees during welding, and the kettle body needs to be heated again during welding. At present traditional heating methods are heating in putting into unified heating furnace with the kettle body, but because the heating furnace only is equipped with a heating chamber and an opening, when the kettle body that needs to take out the use, steam in the heating chamber can run off in a large number, leads to the energy loss in the heating chamber.
