Embodiment 1

[0031] Embodiment 1: 6063 aluminum alloy is used as the raw material. After the rough machining of the 6063 aluminum alloy and the finish machining of stamping and forging, aging treatment is performed on the finished shell semi-finished product.

[0032] Among them, during the aluminum extrusion molding process, the regulating valve is controlled so that the nitrogen gas enters the extrusion device at a speed of 1m 3 / h.

[0033] The aging treatment temperature is 200° C., and the aging treatment time is 2 hours.

Embodiment 2

[0034] Embodiment 2: 6063 aluminum alloy is used as the raw material. After the rough machining of the 6063 aluminum alloy aluminum extrusion and the finish machining of stamping and forging, aging treatment is performed on the semi-finished shell finished after finishing.

[0035] Among them, during the aluminum extrusion molding process, control the regulating valve so that the speed of nitrogen entering the extrusion device is 0.6m 3 / h.

[0036] The aging treatment temperature is 195° C., and the aging treatment time is 3 hours.

Embodiment 3

[0037] Embodiment 3: 6063 aluminum alloy is used as the raw material. After the rough machining of the 6063 aluminum alloy and the finish machining of stamping and forging, aging treatment is performed on the finished shell semi-finished product.

[0038] Among them, during the aluminum extrusion molding process, the regulating valve is controlled so that the nitrogen gas enters the extrusion device at a speed of 0.3m 3 / h.

[0039] The aging treatment temperature is 180°C, and the aging treatment time is 6h.

[0040] The present invention also provides mobile terminal casings, such as middle frames of mobile phones, middle frames of tablet computers, etc., made by using the above-mentioned processing method for mobile terminal casings.

[0041] The above mobile terminal shell processing method adopts the extrusion molding method, no residual material is generated during extrusion, and a large amount of CNC processing is saved, and both rough machining and finishing are carri...

Abstract

The invention relates to a mobile terminal shell and a machining method thereof. The mobile terminal shell machining method includes the steps of providing a metal base material to be machined; putting the metal base material to be machined into an extrusion device for carrying out extrusion of rough machining and obtaining a semi-finished product of the shell; carrying out punching, forging and pressing of finish machining in the extrusion device; and carrying out aging treatment on the metal shell subjected to finish machining and obtaining a finished product after the aging treatment. According to the terminal shell machining method, because the extrusion forming method is adopted, no excess material is generated during extrusion, and a large amount of CNC machining is omitted; and because both the rough machining and the finish machining are carried out in the extrusion device, the waste heat in the extrusion device is utilized for carrying out the punching, forging and pressing of the finish machining, the energy is saved, the environment is protected, the production cost is low, and the manpower investment is small.

Description

technical field [0001] The invention relates to the processing field of mobile terminal equipment, in particular to a mobile terminal casing and a processing method thereof. Background technique [0002] More and more metal casings are used in the casings of current electronic products, such as mobile phones and tablet computers. Taking the metal case of a mobile phone as an example, CNC processing is mostly used in the processing of the metal case of the existing mobile phone. The cost of CNC processing is high, and a lot of waste is generated, and the material utilization rate is low. Contents of the invention [0003] Based on this, it is necessary to provide a low-cost, energy-saving and environment-friendly mobile terminal casing and a processing method thereof. [0004] A method for processing a mobile terminal housing, the steps comprising: [0005] Provide the metal substrate to be processed; [0006] Putting the metal base material to be processed into an extru...
