Description
Technical field
The invention belongs to technical field of surface, are related to a kind of solution aluminium alloy bars material 2A12 electrochemical enamelizing film office
The process of portion's piebald.
Background technique
Currently, carrying out electrochemical enamelizing after being processed into part through timeliness with rods and bars of aluminium alloy 2A12, technique part is wanted
By following process:
Blanking --- timeliness --- machine adds --- electrochemical enamelizing
(1) blanking: blanking outer diameter is Ф 30mm, blanking outer diameter when part outer diameter is Ф 45mm when part outer diameter is Ф 28mm
For Ф 48mm.
(2) timeliness: 180-190 DEG C of aging temp after blanking, time 3-4 hour.
(3) machine adds: carrying out by technique requirement.
(4) it electrochemical enamelizing: is carried out by technique requirement.Using the part of this process, in the porcelain sun of part outer wall
Locally there is speckle phenomena in polarized film part or many places.Speckle phenomena has and gently has weight, and general every batch of part has 3/4 to will appear speckle
Phenomenon.
Summary of the invention
The purpose of the present invention is: it solves after aluminium alloy bars material 2A12 is processed into part through timeliness, when electrochemical enamelizing
The technological problems of film layer part piebald.
The technical solution of the invention is as follows,
(1) blanking: the outer diameter of pieces of bar stock is greater than 15-20mm of part outer diameter；
(2) timeliness: 180-190 DEG C of aging temp after blanking, time 5-6 hour；Bar is uprightly placed and is separated；
(3) machine adds: being machined by technique requirement；
(4) electrochemical enamelizing: removing light except after light, carrying out cyanogen fluoric acid in nitric acid, when removing light between 5-10 second, then by normally
Technique requires to be processed.
Each bar separation gap is not less than 5mm when the timeliness.
The present invention has the advantage that and beneficial effect,
Since aluminium alloy bars material 2A12 is when drawing is become a useful person, the deep layer of external diameter surface 10-16mm is the unstable of material
Layer, therefore, the present invention, by the outer diameter overstriking of blank, enables aluminum alloy to the unstable of bar material 2A12 external diameter surface in blanking
Layer minimizes；In addition when material ages, invention increases aging time and aging temp, solve due to aging temp or
The non-uniform problem of material quality status brought by time deficiency, then aluminium alloy bars material 2A12 is uprightly placed and separated each
Part, to keep the material quality status homogeneity range of material bigger.Increase cyanogen fluoric acid after nitric acid is except light and remove light process, makes part
More evenly, by the part that above-mentioned technique is processed, electrochemical enamelizing film is not in that part or many places spot locally occur to surface state
Line phenomenon, part, after electrochemical enamelizing film layer it is bright, uniformly, it is complete.
Electrochemical enamelizing film of the present invention avoids the occurrence of part completely or speckle phenomena, part porcelain anode locally occur in many places
Film layer is bright, uniform, complete after change.It is suitble to the small part of rods and bars of aluminium alloy 2A12 processing to be also suitble to heavy parts, operating method
It is simple at low cost, it can promote for military project, space flight, ship, civilian etc..
Specific embodiment
Present invention process part will pass through following process:
Blanking --- timeliness --- machine adds --- electrochemical enamelizing
(1) blanking: the outer diameter of pieces of bar stock is greater than 15-20mm of part outer diameter；For example, part outer diameter is Ф
Blanking outer diameter is Ф 38-54mm when 28mm, and blanking outer diameter is Ф 54-60mm when part outer diameter is Ф 45mm.(guarantee that part uses
Outer diameter material settling out removes material external diameter surface instable layer)
(2) timeliness: 180-190 DEG C of aging temp after blanking, time 5-6 hour.(stabilizing material state, makes inside and outside material
Uniformly.)
(3) machine adds: being machined by technique requirement.
(4) electrochemical enamelizing: after nitric acid is except light, increasing cyanogen fluoric acid and remove light, other to carry out by normal process requirement.It is (complete
Full removal piece surface covers object)
By the part that above-mentioned new process is processed, electrochemical enamelizing film is not in that speckle locally occur existing for part or many places
As, part, bright, uniform, the complete of film layer after electrochemical enamelizing
Operation notice:
(1) part blanking outer diameter increases Ф 15-20mm on part outer diameter Ji Chu.
Aging temp cannot be below 180 DEG C after (2) blanking, and the time cannot be less than 5 hours, and when timeliness preferably founds material
It rises and places and separate.(to be separated between material)
The part of (3) electrochemical enamelizing aluminium bar material generally removes light without cyanogen fluoric acid, and only aluminum casting is just removed with cyanogen fluoric acid
Light, for 5-10 seconds between completely removing when piece surface covers when object increases cyanogen fluoric acid except light except light.
