Embodiment Construction

[0023] The invention provides a casing of a mobile terminal and a manufacturing method thereof. The main idea of ​​the present invention is to adopt a concave curved middle frame in the casing of the mobile terminal. Furthermore, the present invention adopts CNC machining to shape the concave arc surface middle frame, avoids manual jig clamping, and grinds and polishes the arc surface, effectively improving the processing efficiency and production yield of the mobile terminal middle frame; and, the present invention adopts concave The arc-shaped middle frame can reduce the destructive effect of external impact on the built-in parts of the mobile terminal, meet the mechanical performance requirements of the mobile terminal shell, and improve the user's comfort, especially in the ultra-thin mobile terminal. higher.

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail ...

Abstract

The invention discloses a housing of a mobile terminal, and a manufacturing method for the same. The method comprises the following steps of: pre-machining a metal material into an appearance structural part with an outer side surface which is a concave arc surface; machining the appearance structural part into a middle frame with a concave arc surface. According to the housing and the method disclosed by the invention, the middle frame with the concave arc surface is used in the housing of the mobile terminal; further, the middle frame with the concave arc surface is machined and formed by a computerized numerical control machine tool, and a mode of manual jig clamping is avoided for burnishing the polished arc surface, thus effectively increasing the machining efficiency and production yield of the middle frame of the mobile terminal; moreover, by using the middle frame with the concave arc surface, the breakage effect of an external impact force on the internal parts of the mobile terminal can be weakened.

Description

technical field [0001] The invention relates to the technical field of process design, in particular to a mobile terminal casing and a manufacturing method thereof. Background technique [0002] At present, the middle frame of an aluminum alloy mobile phone is basically a convex curved surface or a plane. The convex high-gloss arc surface is usually polished and polished manually by clamping with a jig. The main process is to use aluminum alloy forging and pressing, and then clamp it with a jig, and then perform manual grinding and polishing on the linen wheel and cloth wheel several times. However, manually polishing the convex arc surface of aluminum alloy requires a long processing and production cycle, requires experienced polishing personnel, is difficult to standardize, and has a low yield rate. Contents of the invention [0003] Based on the above technical problems, the main purpose of the present invention is to provide a casing of a mobile terminal and a manufac...
