Method for forming metal mobile phone shells

Abstract

The invention discloses a method for forming metal mobile phone shells, and relates to the technical field of mobile phones. The method for forming the metal mobile phone shells includes stamping and bending metal plates to obtain integral outlines of the integrated mobile phone shells so as to obtain initial blank products; carrying out CNC (computer numerical control) machining on the initial blank products to obtain semi-finished products of the metal mobile phone shells; carrying out post-processing on the semi-finished products of the metal mobile phone shells to obtain the metal mobile phone shells. Arc structures are arranged between the side walls and the bottom walls of the integral outlines of the integrated mobile phone shells. CNC machining procedures include (1), milling off burrs on redundant thickness-size sides of the bottom walls and the side walls of the initial blank products under the CNC; (2), inwardly milling the outer walls of arc corners between the side walls and the bottom walls of the initial blank products under the CNC to obtain step structures and respectively forming C-angle edges at the step structures; (3), finely milling the C-angle edges of the step structures under the CNC. The C-angle edges are close to the bottom walls and the side walls of the initial blank products. The method has the advantages that a stamping forming procedure and a CNC machining procedure are combined with each other, so that the metal mobile phone shells can be formed, and the method is stable in process, high in machining precision and production efficiency, short in machining elapsed time and low in production cost.

Description

technical field [0001] The invention relates to the technical field of mobile phones, in particular to a method for forming a metal mobile phone casing. Background technique [0002] As the requirements for the appearance of mobile phones are getting higher and higher, the use of metal shells on the appearance of mobile phones is also increasing. For example, HTC one and other models use metal battery covers to enhance the appearance of the whole phone. At present, some metal shells on the market have a stepped structure, and they are mainly formed by computer numerical control (CNC) processing of metal profiles. CNC machining with hardware steps, because the machining area of ​​the steps is small and requires high precision, if all of them are processed by CNC, it is easy to damage the product and cause poor appearance. [0003] Based on the above, there is an urgent need for a method for forming metal mobile phone casings, which can solve the problems of long processing t...

At present, some metal shells on the market have a stepped structure, and they are mainly formed by computer numerical control (CNC) processing of metal profiles. CNC processing with hardware steps, because the processing area of ​​the steps is small, high precision is required, if all of them are processed by CNC, it is easy to damage the product and cause poor appearance

[0003] Based on the above, there is an urgent need for a method for forming a metal mobile phone case to solve the problems of long processing time, high cost and poor mass production in the existing forming methods for metal mobile phone cases.
