Problems solved by technology

[0006] However, the above-mentioned solution only has higher strength than the through-holes on the metal shell formed by stamping and forming of the thin plate, and does not change the strength of the entire metal shell. The above disadvantages still restrict the application and development of metal shells formed by sheet metal stamping

Embodiment 1

[0044] Such as figure 1 As shown, in this embodiment, a shell processing process according to the present invention adopts sheet metal stamping to form the shell 10, and performs high-gloss edge processing on the outer periphery of the shell 10. A support jig 11 is used to support the inside of the housing 10 before the highlight edge processing.

[0045] By arranging the support jig 11 inside the housing 10, the strength of the housing 10 can be effectively reinforced, and the deformation of the housing 10 under force during the high-gloss processing can be avoided, as well as vibration of knife lines and large and small edges can be avoided.

[0046] In the specific implementation process, the stamping process of the housing 10 can be formed by hot pressing or cold pressing. In this embodiment, the housing 10 is formed by cold pressing, and the supporting jig 11 is fixed on the housing 10. Inside, the casing 10 and the supporting jig 11 are then fixed together on the CNC wo...

Embodiment 2

[0051] Such as figure 2As shown, in this embodiment, a shell processing process according to the present invention uses sheet metal stamping to form the shell 20, and performs high-gloss edge processing on the outer periphery of the shell 20. The support fixture 21 is used to support the inside of the housing 20 before the highlight edge processing.

[0052] In this embodiment, the housing 20 is also formed by cold pressing, and the support jig 21 is fixed inside the housing 20, and then the housing 20 and the support jig 21 are jointly fixed on the High-gloss edge processing is performed on the CNC workbench.

[0053] The supporting jig 21 has an integral structure, and its outer contour shape corresponds to the inner contour shape of the housing 20 . The difference between this embodiment and Embodiment 1 is that in this embodiment, a jig clamping portion for installing or removing the supporting jig 21 is provided on the supporting jig 21 with an integral structure.

Embodiment 3

[0057] Such as image 3 , 4 As shown, in this embodiment, a shell processing process according to the present invention uses sheet metal stamping to form the shell 30, and performs high-gloss edge processing on the outer periphery of the shell 30. A support jig 31 is used to support the inside of the housing 30 before the highlight edge processing.

[0058] In this embodiment, the housing 30 is fixed on the CNC workbench, and then the supporting jig 31 is fixed inside the housing 30 to perform highlight edge processing.

[0059] In order to facilitate the fixing of the support jig 31 after the housing 30 is clamped, the support jig 31 in this embodiment adopts a split structure, which has a jig first part 311 and a jig second part 312. The jig The first part 311 cooperates with the second part 312 of the jig to form the supporting jig 31 , and the outer contour of the supporting jig 31 corresponds to the inner contour of the housing 30 . There is a limiting element between ...

Abstract

The invention discloses a shell machining technique. A shell is formed by stamping a metal plate, the periphery of the shell is subjected to highlight edge machining, and the interior of the shell is supported with a supporting jig before the highlight edge machining. By arranging the supporting jig in the shell, the strength of the shell can be effectively reinforced, receding deformation caused by stressing of the shell in the highlight machining process is avoided, and rough turning marks and unequal edge lengths are avoided. The invention further discloses the shell formed through the shell machining technique. According to the shell, cost is low, quality can be effectively guaranteed, the production technique is simple, and the shell is easy to apply and popularize.

Description

technical field [0001] The present invention relates to the technical field of mobile terminal casings, in particular to a processing technology for a terminal casing, and in particular to a casing processed using the casing processing technology. Background technique [0002] When the light source shines on the object and then reflects into the human eye, the brightest point on the object is the highlight. The highlight is not light, but the brightest part of the object. The highlight is widely used in metal casings in digital products. Usually In order to increase the metallic texture, high-gloss edges are often added to the design of the metal casing. [0003] The high-gloss edge is usually processed by CNC milling. Since the traditional metal shell processing method is also CNC processing, the product strength is very good. When processing the side high-gloss, the product is not easy to deform, and the high-gloss edge is not easy to produce vibration lines. , size side ...
