Problems solved by technology

Most of the existing middle and low-end mobile phone casings are made of plastic. However, plastic mobile phone casings have poor wear resistance, and problems such as scratches and discoloration will occur after long-term use. Therefore, some high-end mobile phones will use metal Shell, thereby improving the wear resistance of mobile phones, but the high cost of mobile phone shells made of metal has become the main problem that limits the price of mobile phones. At present, most manufacturers are looking for new ways to process mobile phone shells to seek A Breakthrough in Manufacturing Costs
[0003] Factors that affect the cost of existing metal mobile phone casings mainly include material costs and processing costs. For example, the existing metal casing processing methods of mobile phones usually use thicker metal plates for CNC processing. Due to the long time and low efficiency of CNC processing, The labor intensity of the required workers leads to a sharp increase in cost. Therefore, how to simplify the processing technology of the metal shell and reduce the processing time of the metal shell is a technical problem that needs to be solved urgently.

Embodiment 1

[0035] Such as Figures 1 to 3 As shown, in this embodiment, a metal shell processing technology according to the present invention includes processing the inner surface 200 and the processing of the appearance surface 300, the processing of the inner surface 200 and the processing of the appearance surface 300 One is CNC forming, and the other is press forming, and the CNC forming is performed after the press forming.

[0036] Compared with the traditional metal shell processing technology, the metal profile is used to perform CNC machining on both sides to form the required shell structure, which greatly reduces the time required for CNC machining and improves the processing efficiency. At the same time, compared with Double-sided CNC machining The material used to process the metal shell can be thinner, and less material needs to be removed during the process, which can save production costs to a large extent.

[0037] Specifically, in this embodiment, the inner surface 20...

Embodiment 2

[0051] Such as Figures 4 to 6 As shown, in this embodiment, a metal shell processing technology according to the present invention includes processing the inner surface 200 and the processing of the appearance surface 300, the processing of the inner surface 200 and the processing of the appearance surface 300 One is CNC forming, and the other is press forming, and the CNC forming is performed after the press forming.

[0052] The structure of the metal shell processed in this solution is the same as that in Embodiment 1, the difference lies in the processing method. In this embodiment, the inner surface 200 is processed by CNC machining and forming on the inner surface 200 of the metal shell for The storage cavity 400 for storing the internal components of the mobile phone, and the storage groove 500 at the bottom of the storage cavity 400 is recessed toward the side of the appearance surface 300 . The appearance surface 300 is processed so that the appearance surface 300 f...

Abstract

The invention discloses a processing technique for a metal shell. The processing technique comprises inner surface processing and appearance processing, wherein one of the inner surface processing and the appearance processing is CNC processing forming and the other one is punching processing forming, and the CNC processing forming is performed after the punching processing forming. According to the scheme, CNC processing is performed on a lateral surface of the metal shell, so that the CNC processing time is reduced, the production efficiency is increased, the metal shell is thinner under the condition that the structure strength of the metal shell is not changed, and the promotion for the thinning of the terminal adopting the metal shell is benefited. The invention also discloses the terminal adopting the metal shell formed according to the processing technique for the metal shell. The terminal is low in cost and is beneficial to popularization and application.

Description

technical field [0001] The invention relates to the technical field of terminal casing molding, in particular to a metal casing processing technology and a metal casing terminal produced by using the metal casing processing technology. Background technique [0002] The mobile phone has gradually become one of the necessities of modern life, and its role is becoming more and more important in various situations such as modern life, work and communication. Manufacturers need to continue to improve, especially the manufacturing cost of the shell of the mobile phone directly affects the total cost of the mobile phone. Most of the existing middle and low-end mobile phone casings are made of plastic. However, plastic mobile phone casings have poor wear resistance, and problems such as scratches and discoloration will occur after long-term use. Therefore, some high-end mobile phones will use metal Shell, thereby improving the wear resistance of mobile phones, but the high cost of ...
