For the deficiency present in background technology, the present invention provides a kind of flow by optimization, operates more succinct one
Body formula lamp radiator processing method.
Technical scheme is used by the present invention solves its problem：The integrated lamp radiator machining method, including with
Lower step：
A, thickness is chosen in 0.2mm --- 0.5mm aluminum sheet material, required for the aluminum sheet material is cut into by plate shearing machine
Size；
B, the aluminum sheet material after cutting being delivered to circle-cutting machine, circle-cutting machine is cut to four corners of aluminum sheet material,
Obtain the aluminium flake of circle；
C, the aluminium flake of circle is delivered into pressing equipment, the mould on pressing equipment applies pressure to aluminium flake centre position,
The centre position of aluminium flake is outstanding, and aluminium flake is deformed into boss structure by circular configuration；
D, by the aluminum semi-finished product of boss structure loaded on spinning machine, the mould on spinning machine is according to angle requirement pair
Aluminum semi-finished product carry out spinning, obtain initial lampshade；
E, initial lampshade carries out physics polishing by polissoir, the inner surface dumped to initial lampshade on polissoir
Sanding and polishing is carried out, until initial lampshade inner surface reaches the finish of no marking；
F, step e initial lampshade is delivered to cleaning equipment, outer surface of the brush on cleaning equipment to initial lampshade
Carry out the cleaning of greasy dirt；
G, the initial lamp after cleaning covers on outer surface spray metal sand；
H, the outer surface for the initial lampshade for being coated with metal sand is immersed in the container of acidic liquid and carries out chemical polishing,
Acidic liquid contacts generation with the metal sand of initial lamp cover outer surface and chemically reacts and start to corrode, until initial lamp cover outer surface
Reach the uneven finish of no concave-convex；
I, lampshade, finished product are taken out.
The measure further taken is：Described acidic liquid is hydrochloric acid, sulfuric acid, nitric acid, acetic acid, carbonic acid, phosphoric acid, Asia
Any one in sulfuric acid, hydrosulphuric acid, acid of hydrochloric acid and nitric acid.
The measure further taken is：Described acidic liquid concentration range is 1 --- 4mol/L.
Further, the preferred 2mol/L of the concentration of described acidic liquid.
For aluminium as a kind of light metal, its compound distributed pole in nature is wide, and chemically and physically special with uniqueness
Property, not only in light weight, quality is hard, and has good ductility, electric conductivity, thermal conductivity, heat resistance and resistance to nuclear radiation,
Metal sand is a kind of powder of stainless steel, has the very filter material of high filtration effect and heat-transfer effect, is fine denier filament production
The ability that a kind of essential excellent filtering material, either anti-pressure ability still catch foreign matter is better than other filterings
Material.It is characterized in：1st, irregular, abnormity simultaneously has more sharp point and more pores construction, and so, the pressure of component can drop to most
It is low, increase the discharge-amount of melt, have bigger capacity to catch the impurity in melt, so as to extend the life-span of component；2nd, it is golden
Category sand has sharp keen edge and corner angle, can capture impurity easily in the melt and can keep very high filter effect,
And the aggregated particle in melt is produced and isolated, this has obvious effect to improving spinning；3rd, the raw material of metal sand are excellent
Matter stainless steel, possess very high compression strength, will not jump in highest state bad, will not be formed tiny at melt pressure
Powder punctures filter net jam spinneret orifice.Therefore, product quality can be improved in outer surface spraying metal sand.
The present invention the advantage is that by such design：
The processing method of the present invention is simple and practical, novel in design, innovatively uses optical reflector with radiator same
Block high heat conduction aluminium sheet material, utilizes integrated punching forming technique straight forming, then the entirety ultimately formed by glossing
Formula structure, without follow-up reprocessing, solve the heat dissipation problem of LED while weight is mitigated, thermal resistance is reduced to minimum, entirely
The automaticity of the process operation of flow is high, while operating efficiency and product quality is improved, can greatly save mould and set
It is standby, reduce equipment disbursement.
Optical reflector and radiator are integrated in one, and integrated level is high, and performance is good.Due to optical reflector and radiator be by
Heat Conduction Material is integrally formed, and heat transfer efficiency is high, and the light source heat radiation effect after mounted LED lamp is good, and LED junction temperature is low, can be significantly
