Shaping method and apparatus of non-plane surface glass products

Abstract

The invention relates to a forming method for a non-flat glass product. The method comprises the following steps: the glass to be processed is placed in a mould, and is subjected to heating and softening treatment, and the glass is heated up to the inherent softening point, wherein the mould has a non-flat forming face, and the forming face is provided with a plurality of micro pores; and in the softening state, a fluid transmission device accurately controlled by parameters transmits power fluid media, and transmits the fluid media to the glass surface through the micro pores on the forming face of the mould; by fluidic power which is formed on the glass surface by the fluid media and corresponds to the non-flat shape of the forming face, and the vacuum negative pressure generated by fluid, the glass with corresponding non-flat shape is precisely formed, and the non-flat glass product is obtained. The invention also provides forming equipment for the non-flat glass product. The forming method of the non-flat glass product and the equipment thereof have the advantages that the forming method of the non-flat glass product and the equipment thereof can simplify production process and improve product yield and production efficiency.

Description

technical field [0001] The invention relates to glass manufacturing technology, in particular to a method for forming a non-planar glass product and equipment thereof. Background technique [0002] In the prior art, with the technical development of mobile communication equipment and audio-video equipment, more and more manufacturers and consumers begin to pursue personalized mobile terminal equipment.

AI Technical Summary

Problems solved by technology

[0003] In the production process of the existing mobile terminal equipment, a glass panel is required for the display screen, especially the application of the capacitive touch screen on the handheld terminal, resulting in the use of a large number of glass panels, and the production process of the glass panel is very Complicated, there are several solutions for the common window shape forming process (before tempering) in the industry: including self-weight hot bending, cold processing engraving and milling, molding hot processing, etc. The processes involved are: cutting; cleaning; profiling ; Polishing in the thickness direction; various edge chamfering; fine grinding; polishing; edge polishing; cleaning; Machinable products are various holes (including round holes, long holes, special-shaped holes, etc.), edges (including straight edges, non-linear edges, grooves, bosses, etc.), chamfering, etc. within the plane range

[0004] The production process of the prior art is mainly cold processing, which basically has the following defects: the production process is complicated, the production cycle is long, and the efficiency and yield are low; Unavoidable microcracks

This kind of process is a labor-intensive industry and will consume a lot of labor; and it can only produce flat glass screens, and cannot efficiently produce non-flat glass screens

If this non-flat glass screen is to be manufactured, a more complicated manufacturing process is required

The surface quality of craft products is guaranteed by grinding and polishing, and the mirror surface quality of products is poor
