Abstract

The invention discloses a forming method and a forming device for a curved surface cover plate. The invention provides the forming method for the curved surface cover plate, which comprises the stepsthat a mold is provided, the mold comprises a forming surface matched with a to-be-formed curved surface cover plate, a flat-plate-shaped mother plate is placed on one side of the forming surface of the mold, and a hollow space is formed between the forming surface and the mother plate; and under a preset temperature condition, the hollow space is subjected to vacuumizing treatment, so that the mother plate is bent and attached along the forming surface under the action of negative pressure to form a curved-surface cover plate.

Description

technical field [0001] The present application relates to the field of cover plate processing, in particular to a forming method and forming device for a curved cover plate. Background technique [0002] With the development of science and technology and the improvement of people's living standards, smart terminals represented by mobile phones and tablet computers have become indispensable consumer electronic products for people. At the same time, people's requirements for such electronic products are getting higher and higher. Taking mobile phones as an example, the cover of mobile phones has gradually developed from the traditional flat cover to the current curved cover. [0003] The existing traditional curved cover plate is processed by hot bending, that is, the temperature of the flat mother plate reaches the softening point by heating first, and then the mother plate is pressed down, so that the mother plate is hot-bent and formed in the mold. Due to the existence of ...
