Traditional mirror surface is all by polishing treatment, and surface is very smooth, such as：Application No. is CN201611120882.0
Application disclose it is a kind of exempting from the manufacturing method of primary coat lamp reflector, and specifically disclose：It makes for being molded car light reflection
The mold of mirror selects high polishability and the mold materials of high-wearing feature to make mode, preceding die holder and the rear die holder of mold, and to institute
It states the preceding die holder of mold and rear die holder carries out quenching treatment to HRC46-48, surface bloom minute surface is carried out to the mode of mold and is thrown
Light, sliding block and mold insert to mold carry out surfaces nitrided stiffened to HRC40 or more；Mold parting surface cooperation surrounding setting is not more than
10mm；Mold circulation waterway uses uniform flow path；Injection molding carries out injection operation using injection molding machine and the mold, obtains required
Workpiece；Ion Cleaning handles the ionization carried out to workpiece surface 4~5 minutes；Vacuum evaporation corresponds to obtain by coating machine
Workpiece aluminized or coated with silicone oil operation.Above-mentioned manufacturing method can produce the lamps and lanterns for automobile, but can exist
Generate dark space and "cut-off"line not enough clearly defect.
Invention content
It is also easy to produce dark space in order to solve car light existing in the prior art, and "cut-off"line not enough clearly defect, this
Invention provides a kind of speculum and its processing method with micro- striped, solves above-mentioned technical problem.The technology of the present invention
Scheme is as follows：
A kind of processing method of the speculum with micro- striped, includes the following steps：
S1, milling cutter is chosen, sets machined parameters；
S2, the inner surface progress striped processing in speculum：Milling cutter is processed in the inner surface of speculum along light direction
The a plurality of micro- striped being mutually parallel；
S3, it aluminizes in the inner surface of speculum.
Can process surface by above-mentioned processing method has the speculum of micro- striped, can be to the light that is projected through speculum
The injection angle of line is adjusted, and is solved car light and is also easy to produce dark space, and "cut-off"line not enough clearly defect.
Further, the milling cutter is spherical cutter.
Further, the tip radius of the spherical cutter is 0.5mm, and when processing, cutter head rotating speed is 30,000 revolution per seconds.
Further, the machined parameters include the streak height and striped step pitch of micro- striped.
Further, the streak height is 0.003-0.03mm.
Further, the striped step pitch is 0.1-0.35mm.
Further, micro- striped extends to another lateral edges from the one side edge of inner surface.
The speculum with micro- striped processed using above-mentioned processing method.
Based on the above-mentioned technical proposal, the technique effect achieved by the present invention is：The present invention with micro- striated structure
Speculum, since the machine direction of micro- striped is along light direction, micro- striated structure directly increases the contact area of light,
The number for increasing light reflection, is on the one hand capable of the horizontal proliferation angle of spread reflection mirror, since the multiple reflections of micro- striped act on,
The diffusion angle of speculum increases 2.5 ° -5 °；Another aspect effective solution light type is uneven and "cut-off"line is unsharp
Problem.High beam, dipped headlight and front fog lamp of the speculum with micro- striated structure of the present invention suitable for automobile.

Specific implementation mode
Present disclosure is further described with reference to the accompanying drawings of the specification.
As shown in figures 1 to 6, a kind of processing method of the speculum with micro- striped is present embodiments provided, including is walked as follows
Suddenly：
S1, milling cutter is chosen, sets machined parameters；
S2, the progress striped processing of inner surface 11 in speculum 1：Milling cutter speculum 1 inner surface 11 along light direction
Process a plurality of micro- striped 111 being mutually parallel；
S3, it aluminizes in the inner surface 11 of speculum 1.
Wherein, in step S1, it can be needed to select different milling cutter specifications according to actual processing, same milling can also be selected
Knife specification selects different milling cutter step-lengths to carry out striped processing, and the micro- striped processed is to optical influence degree difference.It is excellent
Selection of land, the milling cutter of selection are rose cutter, and the tip radius of spherical cutter is 0.5mm, and when processing, cutter head rotating speed is 30,000 turns every
Second.Machined parameters include the streak height h and striped step pitch L of micro- striped 111.Micro- striped 111 in the present invention is a plurality of, and phase
Mutually parallel, as shown in fig. 6, the micro- striped 111 processed is very small, naked eyes are nearly imperceptible, and Fig. 6 is the effect of amplification.
The streak height h of micro- striped 111 is the distance between the highs and lows of micro- striped 111.Preferably, micro- striped 111
Streak height is 0.003-0.03mm.The striped step pitch L of micro- striped 111 is the distance between two neighboring micro- striped 111, specifically
Ground, the striped step pitch L of micro- striped 111 are the distance between the minimum point of two neighboring micro- striped 111.Preferably, micro- striped 111
Striped step pitch L be 0.1-0.35mm.
In step S2, the inner surface 11 using milling cutter in speculum 1 carries out striped processing, is processed using spherical cutter
Micro- striped 111 is arc groove.The micro- striped 111 processed is a plurality of, and a plurality of micro- striped 111 extends along light direction, and
A plurality of micro- striped 111 is mutually parallel.Wherein, light direction F is that in use, light source 2 is located at the focus position of speculum 1
It sets, the light that light source 2 is sent out is after the reflection of the inner surface of speculum 1 towards the external principal direction projected of speculum 1.It is preferred that
Ground, micro- striped 111 extend to another lateral edges along light direction from the one side edge of inner surface 11, i.e., micro- striped is covered in entire
Surface 11.The injection direction of light can be adjusted by the way that micro- striped 111 is arranged, the light uniformity of injection is more preferable, solution
There are the defects of dark space for distance-light and the front fog lamp light type of having determined, but also the "cut-off"line of dipped beam is more clear.
After completing the striped processing of step S2, it may not need and the inner surface 11 of speculum 1 is processed by shot blasting, directly
Inner surface 11 is aluminized, and is formed one layer of aluminium layer on the inner surface 11 of speculum 1 and is realized reflex.
The speculum with micro- striped can be processed based on above-mentioned processing method, speculum 1 has 11 He of inner surface
Outer surface 12, inner surface 11 are reflecting surface, have micro- striped 111 on the inner surface 11 of speculum 1, and micro- striped 111 is very small,
It is visually nearly imperceptible.A plurality of micro- striped 111 is mutually parallel, and extends from the one side edge of inner surface 11 along light direction F
To another lateral edges, a plurality of parallel micro- striped 111 is covered with entire inner surface 11.Micro- striped 111 is arc groove.With micro-
It is coated with aluminium layer on the inner surface 11 of line 111.
A kind of speculum with micro- striped of the present embodiment can be used for the car light of automobile, and light source 2 is arranged in speculum 1
Focal point, the light that light source 2 is sent out pass through with micro- striated structure speculum 1 reflect, due on the inner surface 11 of speculum 1
With micro- striped 111, the reflection direction of some light can change, and some light can realize multiple reflections by micro- striated structure,
Realize the adjustment to radiation direction.The light type projected after final reflection is more uniform, solves long-and-short distant light and front fog lamp light type
There are the defects of dark space, but also the "cut-off"line of dipped beam is more clear.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode within the knowledge of a person skilled in the art can also be in the premise for not departing from spirit of the invention
Under make a variety of changes.
