Description
Technical field
The invention belongs to metal parts electrochemical surface treatment technology, is related to part male cone (strobilus masculinus) non-electrical surfacing guard method.
Background technology
In electrochemical surface treatment, many parts want localised protection, such as and part male cone (strobilus masculinus) due to a variety of causes at present
When non-electrical surfacing is electroplated, the electroless coating on outer cone must be protected.By taking motor elastic shaft male cone (strobilus masculinus) electroless coating as an example, often at present
Guard method is to apply protective paint, and its process is：-- -- coating -- dries -- repairing -- drying -- electricity to pre-electroplating treatment for paint
Plating.Its shortcoming is：Firstth, it is high to the technical requirements of operator；It is manual application during due to construction, uneven distribution, edge
Easily there is pull-away；Easily there is local foaming, leakage protection phenomenon by hot acid, alkali, water, tank liquor etc. in paint film；Secondth, electroplate
Rear depainting is difficult, and part paint film can not purify completely during depainting, or paint stripper corrosion failure coating, product qualification rate are low；The
Three protection periods are grown, and cost is high.
The content of the invention
The purpose of the present invention is：A kind of part male cone (strobilus masculinus) non-electrical surfacing guard method is proposed, to simplify protection technique, drop
The low technical requirements to operator；Avoid the difficult problem of depainting；Shorten protection period, reduce protection cost.
The technical scheme is that：Part male cone (strobilus masculinus) non-electrical surfacing guard method, it is characterised in that use rubber sleeve pair
Non-electrical surfacing is protected, as follows the step of protection：
1st, the size of rubber sleeve is determined：Rubber sleeve is a cone made of natural rubber 4 or oil resistant rubber
Sleeve, smaller diameter end internal diameter D1=cone-(0.5~0.8) of rubber sleeve, unit mm, d1 are that part male cone (strobilus masculinus) non-electrical surfacing is small
The external diameter of diameter end, the larger diameter end internal diameter D2=d2- (0.5~0.8) of rubber sleeve, unit mm, d2 are part male cone (strobilus masculinus) non-electrical
The external diameter of surfacing smaller diameter end, the length L1=L2+ (0.3~0.5) of rubber sleeve, unit mm, L2 are part male cone (strobilus masculinus) electroless coatings
The length in face, the thickness of rubber sleeve is 3mm~5mm；
2nd, rubber sleeve is prepared：Rubber sleeve is suppressed using mould pressing method；
The 3rd, rubber sleeve is installed：
3.1st, protection leather sheath pre-processes：First with metal dish detergent solution cleaned at a temperature of 50 DEG C~70 DEG C 5min~
10min, then 5S~10S is washed with 70 DEG C~80 DEG C of hot water wash 5S~10S, then with cold water, it is a cleaning frequency；Repeat 2
~3 cleaning frequencies；Afterwards with 70 DEG C~80 DEG C of hot-water soak at least 5min；
3.2nd, part pre-processes：Part by treatment before plating is immersed at least 5min in the running water of normal temperature；
The 3.3rd, protection leather sheath is installed：Rubber sleeve is installed in the non-electrical surfacing of part male cone (strobilus masculinus)；
4th, clear water soaks：The part for installing rubber sleeve is put into immersion 5min~10min in normal temperature Rinsing Area, that is, completes zero
The protection of part male cone (strobilus masculinus) non-electrical surfacing.
It is an advantage of the invention that：A kind of part male cone (strobilus masculinus) non-electrical surfacing guard method is proposed, enormously simplify protection technique,
Reduce the technical requirements to operator；Avoid the difficult problem of depainting；Shorten protection period, reduce protection into
This.
