Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] According to an embodiment of the present invention, a method for manufacturing a metal middle frame is provided. figure 1 It is a flowchart of a method for manufacturing a metal middle frame according to an embodiment of the present invention.

[0025] Step S110 , according to the size of the metal middle frame, stamping the metal middle frame, and punching out a connecting bar for connecting two adjacent metal strips in the metal middle frame.

[0026] The metal middle frame includes: a plurality of mutually independent metal bars. The plurality of metal strips can form the shape of the metal middle frame. Both ends of each metal bar are respectively provided with bosses, and the bosses are inside the metal middle frame and per...

Abstract

The invention discloses a metal frame and a manufacturing method thereof. The metal frame manufacturing method comprises steps: according to the size of the metal frame, the metal frame is punched and formed and a connection bar for connecting adjacent two metal bars in the metal frame is punched; appearance processing is carried out on the formed metal frame; and the connection bar in the metal frame is removed. The punching mode is adopted, all metal bars are together processed and formed, size errors to the metal bars can be avoided, and compared with a CNC metal bar processing mode, the method of the invention reduces the manufacturing cost; and the metal bars are connected through the connection bars, the whole appearance processing is carried out, and color difference among the metal bars can be avoided.

Description

technical field [0001] The invention relates to the communication field, in particular to a metal middle frame and a manufacturing method thereof. Background technique [0002] Currently, mobile terminals mostly use metal casings to improve the appearance and texture of the mobile terminals. When the mobile terminal adopts a metal case, the metal case can be used as the radiation unit of the antenna of the mobile terminal. However, if the metal case is used as the antenna radiation unit, it is necessary to make the metal case meet the radio frequency requirements of the antenna. The middle frame is designed as a non-integral structure, that is, a complete middle frame is spliced ​​by multiple metal bars, and a radiation gap is left between two adjacent metal bars to make the middle frame meet the radio frequency requirements. [0003] In order to fix two adjacent metal strips together, on the inner side of the middle frame, bosses (commonly known as feet) are set at both en...
