Abstract

The invention relates to a method for bending forming of a windshield and belongs to the technical field of reforming primary glass. The method comprises the following processing steps: step one, carrying out pretreatment processing on glass; step two, preparing glass bending forming equipment; step three: introducing hot gas for softening the glass; step four, continuously introducing the hot gas, using an air bag to act on the glass, and enabling the glass to be bent and laminated on a bending die; step five, introducing cold gas and carrying out cooling forming treatment on the glass. According to the technical scheme, the problem that the windshield is low in processing efficiency of bending forming in the prior art is effectively solved; the method has the advantages of good glass bending effect, convenience for glass forming, high practicality and high processing efficiency.

Description

technical field [0001] The invention belongs to the technical field of reshaping of primary glass. Background technique [0002] In the past, in the case of bending windshields, the following processing method was mainly used: the windshield was cut into a predetermined size and shape, and it was placed on a bending mold installed in a heating furnace in an atmospheric environment. Heating to the softening temperature of the glass sheet that can be bent and shaped (it varies depending on the glass material, but generally around 550°C to 700°C), and then the flat glass is pulled by its own weight or clamped on both sides of the flat glass to make the flat glass Deforms to follow the shape of the curved die. [0003] However, the existing heating furnace is more common to heat the glass from bottom to top, resulting in uneven heating surface of the glass, resulting in longer heating time, wasting more energy, and low processing efficiency; It takes a long time to wait, and t...
