Description
Technical field
The application relates to the electrodeposited chromium technology of airplane parts, specifically prevents the method for interior barrel part slope place electrodeposited chromium layers blistering.
Background technology
When adopting traditional anode and cathode frock to carry out endoporus electrodeposited chromium to inner core with the part (diagram 1) on slope, part slope place (non-chromium plating face) also can be coated with layers of chrome simultaneously, and due to point effect, make part slope place coating thicker and produce blistering phenomenon than other places, this defect is that airplane parts does not allow existence, needing does over again once again is stripped, the expense that wastes time and energy resource and not easy to operate.And the crisp phenomenon of cyanogen easily occurs part, affect part work-ing life.
Summary of the invention
For the practical situation that production scene exists, the object of the present invention is to provide a kind of method and the electroplating clamp that prevent interior barrel part slope place electrodeposited chromium layers blistering.
A kind of method preventing interior barrel part slope place electrodeposited chromium layers blistering, it is characterized in that, 1) have one with the chrome-plating clamp of part match, this chrome-plating clamp is made up of negative electrode clamping device and endoporus anode, described negative electrode clamping device contains part hook, part dress link, slope guard ring, the top of described part dress link is linked up with part and is fixedly connected with, the outside of part dress link is provided with outside screw and mates with the internal thread of part fixing, the inner side of part dress link is provided with internal thread and mates with the outside screw of slope guard ring, slope guard ring is made up of insulating material, its diameter mates with interior barrel part slope mid diameter, described endoporus anode contains anode canister, bottom set collar and anode hook, bottom set collar is made up of insulating material, its internal thread mates with outside screw bottom anode canister, mates outside it with inside parts, and anode canister top is connected on anode hook by wire, 2) upper end of interior barrel part and part are filled link to be fixedly connected with, make the lower end of slope guard ring be crimped on the slope medium position of interior barrel part, 3) lower end of anode canister is filled the center of link and slope guard ring and interior barrel part through part, fixed by the lower end of bottom set collar and interior barrel part bottom it, 4) hung on the current conducting rod of plating tank by part hook by interior barrel part, in interior barrel part immersion plating liquid, the upper end of anode canister connects electricity by anode hook.
Beneficial effect of the present invention is, both ensure that the chromium plating scope at interior barrel part slope place by chrome-plating clamp, effectively prevent again part coating blistering problem, also ensure that the quality of part coating.Thus improve the once friendship inspection qualification rate of part, local layers of chrome need not be stripped, avoid part to produce cyanogen crisp, avoid producing corresponding production cost and expense.
Below in conjunction with embodiment accompanying drawing, the application is described in further detail

Fig. 2 is the structural representation of negative electrode clamping device
Fig. 3 is for preventing the electrodeposited chromium layers blistering method signal of part inner core slope place
Number description: 1 part, 2 slopes, 3 part hooks, 4 part dress links, 5 slope guard rings, 6 anode canisters, 7 bottom set collars, 8 anode hooks
Embodiment
See accompanying drawing, as shown in Figure 1, the inner tube wall of part 1 needs electrodeposited chromium to the interior barrel part of the application, and there is an annular slope 2 at the proximal port place, upper end of inner tube wall, during prior art plating, can form blocked up coating, occur blistering phenomenon at this slope place.
For solving the problem, the size of each parts of chrome-plating clamp disclosed in the present embodiment all should match with part, guarantees hanging in tank liquor of part safety, and can ensure the processing requirement of coating.
Negative electrode clamping device as shown in Figure 2 contains part hook 3, part dress link 4, slope guard ring 5; the top of described part dress link 4 is linked up with 3 with part and is fixedly connected with; the outside of part dress link 4 be provided with outside screw mate with the internal thread of part 1 port fix, inner side that part fills link 4 is provided with internal thread and mates with the outside screw of slope guard ring 5; slope guard ring 5 is made up of insulating material, and its diameter mates with interior barrel part slope mid diameter.
The part inner core slope place electrodeposited chromium layers blistering method that prevents shown in Fig. 3 is illustrated, endoporus anode contains anode canister 6, bottom set collar 7 and anode hook 8, bottom set collar 7 is made up of insulating material, its internal thread mates with outside screw bottom anode canister 6, with part 1 matching internal outside it, anode canister 6 top is connected on anode hook 8 by wire.
In enforcement, anode hook 8 and anode canister 6 are preferably copper sheet material and make, and to ensure that conduction is good, not easily generate heat.Slope guard ring 5 and bottom set collar 7 are periphery rigid plastics with holes, guarantee that solution circulates in guarantee while electricity.Prevent airbag.The quality of coating of final guarantee part.
During chromium plating, the upper end of interior barrel part 1 and part are filled link 2 be fixedly connected with, make the lower end of slope guard ring 5 be crimped on the slope medium position of interior barrel part, be approximately positioned at 1/3-1/2 position on part slope, play retaining element 8 and protect slope not by the effect of chromium plating; Again the lower end of anode canister 6 is filled the center of link 2 and slope guard ring 5 and interior barrel part 1 through part, fixed by the lower end of bottom set collar 7 with interior barrel part bottom it, play the positioning action of anode canister 6, ensure the center of anode canister 6 and the central coaxial of interior barrel part; Finally interior barrel part 1 is hung on the current conducting rod of plating tank by part hook 3, in interior barrel part immersion plating liquid, the upper end of anode canister 6 connects electricity by anode hook 8, makes to form difference between current between endoporus anode and inner hole part, thus reaches the object of chromium plating.
The present invention adds protection negative electrode at the two ends up and down of interior barrel part, and the slope guard ring 5 namely made by rigid plastics and bottom set collar 7, separate the freeboard of electrolytic solution (namely every electricity) with insulant.Avoid occurring that current concentration is in part two ends and slope place (i.e. most advanced and sophisticated and fringing effect), realizes plating area excessive gently to electroless plating region, no longer occurs the situation of the slope layers of chrome length too large situation of difference and layers of chrome blistering.Effectively stop part short circuit and beaten electricity, played the effect of location simultaneously, ensure that uniformity coefficient and the concentricity of coating, and protected the chromium plating scope of slope position, effectively prevent part coating blistering problem.
Part dress link 4, slope guard ring 5, anode canister 6, these four parts of bottom set collar 7 there is uniform aperture, both ensure that the circulation of solution turn increases annode area, also assures that the balance of each ion in solution, finally ensure that the quality of coating.
For inner hole chrome, must make supplementary anode, its shape should be consistent with part needing the position adding supplementary anode as far as possible.And anode and cathode every electricity, in order to avoid short circuit, must produce and beat electrodisintegration piece surface.The material of the slope guard ring 5 that the application plants and bottom set collar 7 is rigid plastics; serve every effects such as electricity, fixed positions; effectively stopped part short circuit and beaten electricity, the uniformity coefficient of coating, concentricity protect the chromium plating scope of slope position, prevent part coating blistering problem.Realize plating area excessive gently to electroless plating region, no longer occur the situation of the slope layers of chrome length too large situation of difference and layers of chrome blistering.
