Example Embodiment

[0038] Example one:

[0039] Step A11, heating the glass / ceramic to be formed with cracks integrally or locally;

[0040] In step A12, the glass / ceramic is quenched on one side, so that cracks grow along the quenching direction, and the glass / ceramic is formed.

Example Embodiment

[0041] Embodiment two:

[0042] Step A21, local heating is performed on the region to be molded of the glass / ceramic to be molded;

[0043] Step A22, the glass / ceramic is quenched on one side to generate cracks, and the cracks are grown along the quenching direction to realize glass / ceramic molding.

Example Embodiment

[0044] Embodiment three:

[0045] Step A31, freezing the glass / ceramic to be formed with cracks integrally or partially;

[0046] In step A32, the glass / ceramic is subjected to single-sided rapid heating, so that the cracks grow along the direction of the rapid heating, and the glass / ceramic molding is realized.

Abstract

The invention is applicable to a glass/ceramic deep processing manufacturing technology and provides a glass/ceramic precision molding method and molding equipment. The molding method comprises the following steps of: forming temperature difference in the whole area of local area of two surfaces of glass/ceramic to be molded so as to generate or extend cracks on the surface of or inside the glass, and controlling the growth of the cracks by the utilization of the direction of the temperature difference so as to realize the molding of the glass/ceramic. By the formation of temperature difference on the two surfaces of the glass/ceramic to be molded and according to different thermal expansion coefficients, cracks generated on the glass/ceramic grow along the direction of the temperature difference or existed cracks are extended along the direction of the temperature difference, thus realizing glass/ceramic precision molding. Relative to traditional technologies such as punching molding and the like, the method provided by the invention can be used to improve the glass/ceramic molding efficiency and quality to some extent.

Description

technical field [0001] The invention belongs to the technical field of glass / ceramic manufacturing, and in particular relates to a glass / ceramic deep processing molding method and molding equipment. Background technique [0002] Glass is a transparent solid substance, the main component is silicon dioxide. At present, glass products are used in many devices, some for protection, and some as beautiful decorations, such as the protection of mobile phone windows and touch screens. The screen has both the above two functions, and its production process is generally: cutting --- grinding --- punching --- hole chamfering --- polishing --- cleaning --- chemical strengthening ---.  … Among them, punching holes in glass is generally done by cold processing, which is usually realized by machining tools such as CNC drilling and bench drills, but this punching method can easily cause glass to break. [0003] As an important structural material, ceramics have the advantages of high stre...
