On 200, the adhesion between plastic parts 300 and frame 100 and middle plate 200 is further strengthened, lifting metal center is external
The resistivity of boundary's impact.
The present invention also provides a kind of metal center processing technology, refering to Fig. 9, including following key step:
S410, passes through extrusion process and CNC technique machine-shapings frame 100.First, while refering to Fig. 1 and Fig. 2, passing through
Extrusion process processes the embryo material of frame 100 to form ring-type, then by CNC techniques the embryo material of frame 100 is carried out partial operation with into
Type frame 100, for example, making antenna seam 130, riveted holes 120, and strengthening groove 111 or reinforced hole etc. add on the embryo material of frame 100
Strong ties structure 110 etc..
S420, plate 200 in being molded using extrusion process.Simultaneously refering to Fig. 3 and Fig. 4, by die casting machine by the metal of melting
Injected under high-voltage high-speed in compression mod, and plate 200 in curing molding under high pressure, strengthening groove 111 or reinforced hole etc. are strengthened connecting
The disposal molding in compression mod of binding structure 110.Extrusion process eliminates the CNC manufacturing procedures of complexity, improves metal center
Processing efficiency, the middle plate 200 after die cast has surface roughness good, the big advantage of mechanical strength, meanwhile, reduce
The allowance of CNC processes, has saved the cost of raw material.
S430, by the middle riveting of plate 200 in the frame 100.Simultaneously refering to Fig. 5 and Fig. 6, by middle plate 200
Lug 210 be pressed on the step surface 140 of frame 100, and make riveted holes 120 on step surface 140 and lug 210 mutually right
Together, rivet 150 is put into riveted holes 120, rivetted rivet 150 by riveting gun, so as to realize frame 100 and middle plate 200
Between non-dismountable connection.In fact, the preliminary connection function to frame 100 and middle plate 200 is played in riveting, middle plate 200
There is the gap of a determining deviation between the inner surface of edge and frame 100, so as to the installation of follow-up plastic parts 300.
S440, the plastic cement of melting is injected between middle plate 200 and frame 100 in gap.It is first simultaneously refering to Fig. 7 and Fig. 8
First the frame 100 riveted and middle plate 200 are clipped in mold cavity, then by injector by plate in the injection of the plastic cement of melting
Between 200 and frame 100 in gap, the plastic cement of melting penetrates into the strengthening groove 111 on middle plate 200 and frame 100 or added simultaneously
Qiang Kongzhong, after the plastic cement of melting is frozen into plastic parts 300 of solid-state, plastic parts 300 plays good connection and sealing effect,
Middle plate 200 and frame 100 can be combined into the metal center of an entirety, it is ensured that metal center possesses good mechanical strength.

Diphenyl sulfide) it is made.
S450, cools down and the metal center after shaping is surface-treated.Due to melting plastic cement frame 100 with
Excessive phenomenon is there may be in gap between plate 200, so as to cause the plastic parts after coagulation forming 300 with respect to the He of frame 100
Protrude certain height in the outer surface of middle plate 200.Therefore, after the coagulation forming of plastic parts 300, using CNC finish-milling technique milling plano-convexs
The plastic parts 300 gone out, it is ensured that the presentation quality of metal center.In certain embodiments, can be by frame 100 and middle plate 200
The certain thickness of outer surface milling, further to improve the flatness of metal center outer surface.
Then blasting treatment is carried out to metal center outer surface of the milling after flat, in certain embodiments, can be using machinery
Sand blasting process obtains Aluminum profile on outer frame surface in a metal, for example, by compressed air by abrasive material (diamond dust, stone
Sand, copper ore or iron sand etc.) injection is to the outer surface of frame 100 and middle plate 200 at a high speed, in the abrasive material sprayed at a high speed to rushing
Hit with shear action, the pollutant such as grease adhered on metal center is eliminated, so that frame 100 and middle plate 200 is outer
The mechanical performance of surface acquisition certain cleannes and roughness, frame 100 and middle plate 200 is improved, and is improved in metal
The wearability of the fatigue resistance of frame and its outer surface, strengthens the adhesive force of subsequent oxidation film, so as to extend the durable of oxide-film
Property.In other embodiments, it can be acted on by the pitting of chemical mediator on metal center outer surface and obtain chemical etching granulation.
Finally, anodized is carried out to the outer surface after blasting treatment.Using metal center as anode, in electrolyte
Middle reaction setting time, the outer surface of metal center forms layer oxide film, and the oxide-film can be 20 μm or so.Due to the oxygen
Change the effect of film, improve the hardness and abrasion resistance properties of metal center outer surface, extend the service life of metal center.
In certain embodiments, before middle plate 200 and frame 100 are riveted, frame 100 and middle plate 200 are subjected to nanometer
Change is handled.Further to improve the adhesion between plastic parts 300 and frame 100 and middle plate 200.Refering to Figure 10, at nanosizing
Reason mainly comprises the following steps：
S510, first, centering plate 200 and frame 100 carry out degreasing and decontamination.During machine-shaping, the middle He of plate 200
Grease and other pollutants are attached with frame 100, middle plate 200 and frame 100 are immersed to soak in the alkali lye of certain pH value set
Fix time, centering plate 200 and frame 100 are carried out effectively degreasing and abatement processes by alkali lye.Then, by middle plate 200 and frame
100 take out from alkali lye and are soaked a period of time in the acid solution of certain pH value, so as to will be attached on middle plate 200 and frame 100
Alkali lye neutralized.
S520, then, leaching in solution containing amine substance (T liquid, Taiseiplas liquid) is put into by middle plate 200 and frame 100
Steep and corrosion is formed into cellular pits on setting time, the edge of middle plate 200 and the inner surface of frame 100.This is received
The sectional dimension of meter level pit is A, and A span can be 20nm≤A≤40nm.
S530, finally, is washed and is dried to the middle plate 200 and frame 100 after corrosion, so as to the note of melt plastic cement
Penetrate.
Due to being formed with pits on middle plate 200 and frame 100, the plastic cement of melting can equally penetrate into wherein, so that
The plastic parts after shaping 300 is set to be formed " crab-bolt effect " with middle plate 200 and frame 100, plastic parts 300 and frame 100 and middle plate
Adhesion between 200 is significantly strengthened.
