Specific embodiment
Hereinafter embodiments of the invention will be described in detail by accompanying drawing.
First, Fig. 1 is illustrated that the extruded frame that the extruding of aluminium base is fabricated to one side H types of the invention(100)Processing Preparatory stage.
In the present invention, the extruded frame of preparatory stage is processed(100)It is one side H types, but it is also possible to by identical method Make the one side formed as shown in Figure 13 a and Figure 13 b.
In addition, as shown in Fig. 2 being the first stage:According to the mobile phone metal shell that the final process segment obtains(10)It is whole Body, the processing preparatory stage is squeezed into the extruded frame of H types(100)Predetermined length according to being previously set is blocked.
At this moment, the intermediate plate (120) that the left and right outer wall (110) for being blocked under state according to predetermined length and its inner side are set, In the state of mobile phone metal shell (10) is processed into, illustrated periphery in above-mentioned left and right outer wall (110) formation Fig. 7 to Figure 12 Side (11), intermediate plate (120) basis of formation plate (12).
In this state, as shown in figure 3, being second stage:The remainder of intermediate plate (120) passes through cutting processing, Metal framework (200) is formed, and removes intermediate plate (120) unnecessary portion and form spatial portion.Wherein, cutting processing is pressure Cut one kind of processing.
Now, spatial portion (a) is formed by removing the unnecessary part of intermediate plate (120), as shown in figure 4, need to be the 3rd Stage makes the two ends of left and right outer wall (110) preferably carry out warpage within the bounds of possibility.
Fig. 4 is the phase III:Above-mentioned second stage by cutting processing remove intermediate plate (120) unnecessary portion it Afterwards, by left and right outer wall(110) two ends warpage is processed to form corner angle.
In order to the two ends of the left and right outer wall (110) to the metal framework (200) by cutting processing carry out warpage processing, In the state of remainder cutting processing removal unnecessary part as shown in Figure 3, the present invention uses fixture (omitting diagram) folding The faceted portions of opening of the bent left and right outer wall (110) in rear and front end, make metal framework(200)Corner angle maintain circular state.
As shown in figure 5, being fourth stage:In removal intermediate plate (120) unnecessary portion of above-mentioned phase III and warpage In the state of the two ends of processing left and right outer wall (110), processing is connected to the opening portion of the rear and front end of metal framework (200) (210) metal framework module(300).
The processing of metal framework (300) module can be using NC processing methods or aluminium base extruding formation method or by compression shear Method is blocked unnecessary length and is processed into required shape.
But should be noted that the purpose of any processing method for using herein is all not limited to the present invention.
It it was the 5th stage as shown in Figure 11, Figure 12:In part (210) shape of the rear and front end opening of metal framework (200) Into insulating space (b) increase by one layer in the state of, injection mold utilize insert molding method, by the above-mentioned 4th shown in figure six Metal framework module (300) insertion that formation is processed in stage forms mobile phone metal shell(10).
Then, it was the 6th stage as shown in Figure 11, Figure 12:The mistake of insert molding is being carried out to mobile phone metal shell (10) In journey remove remainder, it is necessary to when can be processed by NC.
Afterwards, the 7th stage:To mobile phone metal shell(10)It is surface-treated, makes outside the mobile phone metal of the 6th stage formation The surface of shell (10) is presented various colors.
In another embodiment, as shown in Figure 9 and Figure 10, it is formed only in metal framework module (300) in the 5th stage Side, therefore, can be more prone to insert molding, processing can again be more prone to.
In another embodiment, as shown in Figure 7 and Figure 8, metal framework module (300) is not used, therefore in fourth stage not Need to process metal framework module, so the processing of fourth stage in the present embodiment is unnecessary process.And in the 3rd rank Duan Zhong, removes intermediate plate (120) unnecessary portion, and the two ends of warpage processing left and right outer wall (110) are formed in this case There is no the metal framework (200) of opening portion, the 5th rank is not directly connected to from the phase III by fourth stage in this case Section.
The framework that one side " H " type is squeezed into the processing preparatory stage described in the present invention, its left and right outer wall (110) structure Into the periphery sides (11) of the mobile phone metal shell (10) of terminal stage, the one side of intermediate plate (120) constitutes liquid-crystalline glasses and is used for The substrate of stabilization and fixed assembling electronic accessory product, another side is constituted and can be used for the base plate (12) in the space of actual load battery.
In addition, the present invention is in order to process metal framework module (300), divides equally and extrude the one side to be formed in the processing preparatory stage The extruded frame of H types, one side T-shape is processed into by NC processing methods, and itself and periphery sides are made during insert molding (11) unified specification and material are kept as far as possible.
Figure 13 a of the present invention are shown a case that suitable for battery outer-installed type, Figure 13 b show suitable for battery built in type or The situation of outer-installed type.The present invention is illustrated with the situation of battery built in type or outer-installed type.
It is however noted that, the purpose of battery built in type or outer-installed type is not intended to limit the invention.
In addition, Figure 14 a to Figure 14 d are illustrated that the extruded frame that the present invention is obtained in processing preparatory stage extrusion molding (100) periphery of the mobile phone metal shell (10) of the final finished for, being obtained by processing preparatory stage and the first to the 7th stage The embodiment of the various shapes of formation on side (11).Can be extruded according to various shapes during aluminium base extrusion molding, So as to have the advantages that handling ease and design various.
Figure 16 a to Figure 16 d are illustrated that an alternative embodiment of the invention.
As illustrated in fig 16 a, it is the processing preparatory stage:Extruded aluminium base is made the extruded frame (100) of one side " H " type;And First stage:According to the mobile phone metal shell that the final process segment obtains(10)Entirety, by the above-mentioned processing preparatory stage extruding Into the extruded frame of H types(100), blocked according to the predetermined length being previously set, form left and right outer wall (110) and intermediate plate (120);
Second stage:By the remainder of above-mentioned intermediate plate (120) by cutting processing, metal framework (200) is formed, in removal Between in plate (120) unnecessary portion form spatial portion (a);Wherein, cutting processing is one kind of compression shear processing;
Phase III:After above-mentioned second stage removes intermediate plate (120) unnecessary portion by cutting processing, by outside left and right Wall(110) two ends warpage is processed to form corner angle;
Fourth stage:In the state of the two ends warpage of left and right outer wall (110) is processed and to form corner angle by the above-mentioned phase III, will be from The one or both ends warpage of prominent intermediate plate forms the upstanding wall consistent with left and right outer wall in the middle of the corner angle of metal framework (200) (210a);
5th stage:Between the upstanding wall (210a) and warpage that are formed in above-mentioned fourth stage and the left and right outer wall for forming corner angle In the insulating space (b) of formation, plastic cement insertion body (13) is embedded in using insert molding method, forms mobile phone metal shell(10).
It should be noted that being illustrated with H type extruded frames in the processing preparatory stage in the present invention, but simultaneously not only This is limited only to, and same processing mode can also be used to U-shaped extruded frame according to battery built in type or outer-installed type.Together When, insert molding method is a kind of embodiment, also can be using the other method for filling insulating space.
