Embodiment 1

[0037] Such as Figure 1 to Figure 11 As shown, this embodiment discloses a process for processing a middle frame of a mobile phone, including the following steps:

[0038] a, such as figure 1 As shown, two linear profiles 11 with riveting grooves 12 are produced according to the required size, the linear profile 11 is made of soft metal material, and the riveting grooves 12 penetrate both ends of the linear profile 11;

[0039] b, such as image 3 As shown, each linear profile 11 is bent into a U-shaped frame 11a, and the riveting groove 12 is located inside the U-shaped frame 11a;

[0040] c, such as Figure 5 As shown, a metal middle plate 20 of a required size is provided, and a riveting protrusion 21 is CNC machined on the edge of the metal middle plate 20, and the maximum vertical width of the riveting protrusion 21 is less than or equal to the minimum vertical width of the riveting groove 12;

[0041] d, such as Figure 7 As shown, the metal middle plate 20 and the two U-shaped...

Embodiment 2

[0055] The difference between this embodiment and the first embodiment is that the linear profile 11 and the riveting groove 12 are processed and formed simultaneously. Preferably, the linear profile 11 preset with the riveting groove 12 is formed by extrusion.

Embodiment 3

[0057] The difference between this embodiment and the first embodiment is: the depth of the riveting groove 12 is 0.8mm and the width is 3.3mm; the depth of the riveting protrusion 21 is 0.8mm, the upper width is 3.3, and the lower width is 0.3mm shorter than the upper width, namely The lower width is 3mm.

Abstract

The invention discloses a mobile phone middle frame processing technology which comprises the following steps: manufacturing two linear section bars with riveting grooves according to the size of an outer frame, wherein the linear section bars are made of a soft metal material; bending the linear section bars into U-shaped frames; providing a metal middle plate of the required size and CNC processing riveting protrusions at the edge of the metal middle plate; assembling the metal middle plate and the two U-shaped frames into a mobile phone middle frame and inserting the riveting protrusions into the riveting grooves to be in clearance fit with the riveting grooves; extruding an outer frame formed by the two U-shaped frames in the direction perpendicular to the metal middle plate and deforming the U-shaped frames to buckle the riveting protrusions in the deformed riveting grooves to make the metal middle plate and the outer frame be tightly connected. The mobile phone middle frame processing technology disclosed by the invention can generate very little intermediate waste materials and greatly reduces waste material processing time; furthermore, the technology has the advantages ofmore simpleness and easiness in operation; a processing efficiency is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of mobile phone component processing, in particular to a mobile phone middle frame processing technology. Background technique [0002] The metal shell used on the mobile phone not only has a beautiful appearance, but also has the advantages of fine touch, wear resistance, drop resistance, corrosion resistance, and easy recycling and reuse when discarded, because it is very popular with consumers. Among them, the middle frame, as an important part of the mobile phone, has a smooth appearance and a complicated inner structure. At present, the general methods for the middle frame of mobile phones are: 1. The whole piece of aluminum alloy, stainless steel, steel and other plates are processed by CNC chipping, drilling and milling. This method consumes large raw materials, CNC processing volume, low processing efficiency, and high cost; but The technology is relatively simple, and it is currently the main processing...
