Please refer to Fig.1 and Fig. 2, the application provide a kind of method for producing shell, the method for producing shell is used to make shell
Body.The housing 100 is process by metal sheet.The outer surface of the housing 100 is made of multiple curved surfaces, so that described
100 appearance of housing is mellow and full, increases user experience.It is understood that the housing 100 is applied to mobile terminal, the movement
Terminal can be mobile phone, tablet computer or laptop etc..In present embodiment, the housing 100 is the back-cover of mobile phone.
Shown such as Fig. 2~Fig. 9, the method for producing shell includes：
Step 101：There is provided the first housing base 10, first housing base 10 has first surface 11 and with described the
The opposite second surface 12 in one surface 11, and it is opened in the second surface 12 and the inner cavity extended towards the first surface 11
13。
In present embodiment, the periphery bending of the first surface 11 is set.The first surface 11 adds peripheral region
Work resistance is less than the second surface 12 in the processing resistance of peripheral region, and the periphery of the first surface 11 is added with facilitating
Work.First housing base 10 is rectangular metal plate.The first surface 11 has two 111 Hes of long side being oppositely arranged
Two short sides 112 being oppositely arranged.The step 101 includes：
Plate 20 is provided, the plate 20 has the second largest face that the first big face 21 and relatively described first big face 21 are set
22。
In present embodiment, the plate 20 is rectangular metal plate.The plate 20 is obtained using cutting technique.First
Big face 21 and the second largest face 22 are rectangular surfaces.The first big face 21 is burnishing surface, and the second largest face 22 is burnishing surface.
, it is necessary to the described first big face 21 and the second largest face 22 before the described first big face 21 and the second largest face 22 processing
Cleaning, removes the dust on the first big face 21 and second face 22.Remove the burr of the periphery of the plate 20.To institute
Polish the side for stating plate 20 so that the plate 20 it is neat, avoid in the process to the plate 20, institute
State 20 discontinuity equalization of plate so that the deformation of the plate 20 is balanced, improves appearance.The plate 20 is heated.Will
The plate 20 is positioned in heating equipment so that 20 temperature of plate is increased to preset value.The plate 20 is after the heating
Intermolecular stress reduces so that 20 deformational stress of plate reduces, and facilitates the plate 20 to be molded during following process.
The first big face 21 and second largest face 22 of the plate 20 is processed, forms first surface 11 and second surface respectively
12。
In present embodiment, the first big face 21 forms institute described in the periphery in the first big face 21 for extruding the plate 20 first
First surface 11 is stated, and molds the clout side 23 for connecting 11 periphery of first surface.
