For achieving the above object, the present invention takes following technical scheme: a kind of two-sided engraving method for metal products, comprises the following steps:
(1) carry out mask process at the upper surface of metal products and lower surface, described upper surface is corresponding consistent with the mask layer pattern of lower surface;
(2) first the metal products upper surface after mask or lower surface are placed in etching machine and carry out spray etching, then metal products is overturn, the lower surface of metal products or upper surface are placed in etching machine and carry out spray etching, complete the two-sided etching to metal products; Etching solution in described two-sided etching comprises the component of following mass ratio: iron trichloride 20 ~ 40%, hydrochloric acid 3 ~ 5%, nitric acid 1 ~ 2%, hydrofluoric acid 0.3 ~ 0.5%, hydrogen peroxide 0.2 ~ 0.4%, sodium-chlor 0.1 ~ 0.3%, surplus are water;
(3) demoulding process is carried out to the metal products after two-sided etching, removing mask layer, and carry out cleaning, polishing aftertreatment.
As the preferred implementation of the two-sided engraving method for metal products of the present invention, before the mask process of carrying out step (1), first surface finish process is carried out to metal products, the roughness≤1.6Ra of the surface of metal product after process.Described metal products, before carrying out mask process, first carries out the pre-treatments such as surface finish, makes the roughness≤1.6Ra of the surface of metal product after processing, can meet the adhesion requirements of mask layer to surface of metal product, better facilitate subsequent masks process.
As the preferred implementation of the two-sided engraving method for metal products of the present invention, in the mask process of described step (1), the mask layer pattern of described metal products upper surface and lower surface is the circular cavernous structure of array distribution.When the upper surface of described metal products and the mask layer pattern of lower surface are the circular cavernous structure of array distribution; circular hole place is the exposed region of surface of metal product; cover without mask layer; the capped protection of elsewhere; in subsequent etch process; exposed circular hole place is etched removal, and forms circle hole shape pit on the surface of metal products.Because described metal products upper surface is identical and unanimously corresponding with the mask layer pattern of lower surface, therefore follow-up respectively two-sided etching is carried out to the upper surface of metal products and lower surface time, described metal products upper surface and the exposed border circular areas of lower surface corresponding, after two-sided etching and processing, manhole can be formed on described metal products.Certainly, described mask layer pattern is not limited to the circular cavernous structure of array distribution, also can be the cavernous structures such as square, pentagon, the Polygons of array distribution, according to the shape needing the through hole formed on metal products, determine the shape of described mask layer pattern.
As the preferred implementation of the two-sided engraving method for metal products of the present invention, carry out mask process at the upper surface of metal products and lower surface and specifically comprise following process: at upper surface and the lower surface coating sensitive materials of metal products, described upper surface with the sensitive materials of lower surface attach the film that pattern is completely corresponding identical, pattern on the described film is the circle of array distribution, then exposure-processed is carried out, after exposure, the film is removed, and the uncured sensitive materials of the cleaning described metal products upper surface of removing and lower surface, the sensitive materials that described metal products upper surface and lower surface solidify is mask layer.The key of mask makes the mask layer pattern of metal products upper and lower surface completely corresponding identical, the precision of such guarantee through hole that two-sided etching and processing goes out on metal products.For this reason, the first upper surface at described metal products and lower surface evenly apply sensitive materials, then circular dimension, the on all four whole Zhang Feilin of pattern-pitch is designed as exposing material, with whole Zhang Feilin mid-line for line of delimitation, by folding for the film separately symmetrical, with position, the film is attached in the same way on the sensitive materials of described metal products upper and lower surface, to ensure that the center of circle circular on film pattern in described metal products upper and lower surface is aimed at.Then exposure-processed is carried out, on the described film, circular pattern section is black, light tight, and elsewhere is transparent, energy printing opacity, therefore in exposure process, place transparent on the light therethrough film, react with the sensitive materials of metal products upper surface and lower surface, the sensitive materials corresponding with the transparent place of the described film is made to be fixed on upper surface and the lower surface of described metal products, form mask layer, and described metal products upper surface and the lower surface sensitive materials corresponding with the circular pattern section of the film uncured.After exposure-processed, the film is removed from the upper surface of described metal products and lower surface, and clean sensitive materials uncured on described metal products upper surface and lower surface, the circular cavernous structure mask layer of completely corresponding identical array distribution is namely formed at upper surface and the lower surface of described metal products.
