Embodiment Construction
[0017] An embodiment of a manufacturing method of a stainless steel mobile phone frame of the present invention will be described in detail below with reference to the accompanying drawings.
[0018] A kind of manufacturing method of stainless steel mobile phone outer frame of the present invention, comprises the following steps:
[0019] a) Design the frame structure of the mobile phone;
[0020] b) Select a steel bar of the opposite sex with a suitable size, and cut it at the position to be cut on the steel bar according to the frame structure design;
[0021] c) Use a processing machine to bend the cut steel bar to be bent, and process it into two bent parts, both of which are U-shaped frames with unequal sides and the two bent parts The components can be connected and assembled into a mobile phone frame;
[0022] d) Connect the two bending parts and weld the joints;
[0023] e) Grinding and polishing the weld;
[0024] f) Cleaning the surface of the above-mentioned out...

The invention discloses a production method of a stainless steel outer frame of a mobile phone. The method includes designing an outer frame structure of the mobile phone; selecting a figured steel bar in an appropriate size, and trimming at a position to be trimmed on the steel bar according to the structural design of the outer frame; bending positions required for bending on the trimmed steel bar through a processing machine, and processing forming two bending members which can be connected to combine the outer frame of the mobile phone; connecting the two bending members and performing welding joint at the seam; performing grinding and fine polishing on the welded position; and cleaning the surface of the outer frame after processing forming. The stainless steel outer frame of the mobile phone produced by the method is good in shape flatness, and stable in mechanical properties, particularly at the bending position; the operation is simple; and high-quality requirements in the electronic industry can be satisfied.
Description
technical field [0001] The invention relates to a mobile phone outer frame, and specifically provides a method for manufacturing a stainless steel mobile phone outer frame. Background technique [0002] Stainless steel is widely used in heavy and light industries and various daily necessities due to its excellent corrosion resistance, formability, compatibility and toughness in a wide temperature range. At present, a large number of stainless steel accessories have emerged in the field of mobile phone related manufacturing. It is mentioned in CN201020235467.1 that the steel plate material has a good anti-radiation function of mobile phones and can effectively reduce the harm of mobile phone radiation to the human body. Mobile phone cases (frames) made of stainless steel materials, etc. However, the stainless steel frame made by the existing technology is prone to complicated process, poor plate shape flatness, and unstable mechanical properties, especially the unstable proc...
