Ship, typically all use cathodic protection, steel and iron parts under cathodic protection effect not by seawater corrosion, but with the reach of science
And the requirement of precision instrument is improved constantly in ship, does not allow have interference power around transmission system, existing hydraulic bolt
DC current can not be blocked, so that the normal operation with jamming equipment can be influenceed.
The content of the invention
For it is above-mentioned can not block DC current the problem of, the invention provides a kind of hydraulic bolt processing technology, its energy
It is enough effectively to block DC current, play insulating effect.
Its technical scheme is such：
A kind of hydraulic bolt processing technology, it is characterised in that it comprises the following steps：
（1）Forging is machined out to be formed；
（2）Dried after being cleaned to tapered sleeve and nut；
（3）Blast operation is carried out after cleaning operation；
（4）Tapered sleeve outer round surface and nut plane are sprayed at after aluminium wire is melted using flush coater；
（5）The surface that thermal spraying is completed carries out mill processing and reaches coarse requirement；
（6）Secondary cleaning is carried out to part；
（7）Coat insulated paint in the part that need not spray aluminium wire in tapered sleeve and nut surface；
（8）Hard anodizing processing is carried out to its surface again.
It is further characterized by, step（1）Middle tapered sleeve outer surface and nut plane, which leave 0.3-0.4mm sizes, to be used for
Thermal spraying；
Step（2）Middle use YB-5 cleaning agents or degreaser soak 10-20min, are then cleaned with hot water, cold water wash after-blow
It is dry；
Step（2）Middle cleaning operation is first soaked using gasoline, then is scrubbed, and finally makes gasoline volatilization；
Step（3）First non-blast part is carried out before middle blast operation to block protection；
Step（3）Middle blast operation is used after 60 mesh diamond dust, blast with roughometer detection roughness, when reaching Ra3.0, is stopped
Only blast is operated, and removes diamond dust on tapered sleeve and nut, and thermal spraying operation was carried out in 4 hours；
Step（4）The middle aluminium wire using a diameter of 2.0mm carries out thermal spraying, and coating layer thickness is more than 0.2mm
Step（5）Middle use YB-5 cleaning agents or degreaser soak 10-20min, are then cleaned with hot water, cold water wash after-blow
It is dry；
Step（5）Middle cleaning operation is first soaked using gasoline, then is scrubbed, and finally makes gasoline volatilization；
Step（7）Directly brushed using G-52-31 vinyl perchloride anti-corrosion paints.
After the present invention, the part contacted in hydraulic bolt tapered sleeve outer surface and nut plane with flange hole is coated with aluminium
Layer, and carry out anodized and form a layer insulating, DC current has been effectively blocked, insulating effect is played.
Brief description of the drawings
Fig. 1 is bolt arrangement schematic diagram of the present invention；
Fig. 2 is processing process figure of the present invention.
Embodiment
As shown in Figure 1, a kind of hydraulic bolt, it includes bolt body, tapered sleeve and two nuts, it is characterised in that described
Tapered sleeve is cylindrical and nut plane on be coated with aluminium lamination, and carry out anodized and form a layer insulating.
As shown in Figure 2, its processing technology comprises the following steps：
（1）Forging is machined out to form bolt, 0.3-0.4mm sizes are left on bolt inner sleeve surface is used for thermal spraying；
（2）Dried after being cleaned to bolt, using any in following two ways：Soaked using YB-5 cleaning agents or degreaser
10-20min is steeped, is then cleaned with hot water, is dried up after cold water wash；Or cleaning operation is first soaked using gasoline, then scrubbed,
Finally make gasoline volatilization；
（3）Blast operation is carried out after cleaning operation, first non-blast part is carried out before blast operation to block protection, blast operation is adopted
With 60 mesh diamond dust, roughness is detected with roughometer after twice of blast, when reaching Ra3.0, stops blast operation, removes tapered sleeve
With diamond dust on nut, thermal spraying operation was carried out in 4 hours；
（4）Tapered sleeve and nut surface are sprayed at after aluminium wire is melted using flush coater, details are provided below：1. open automatic
Air switch, flush coater portable lamp is bright, blower fan normal rotation；2. manual wire feed button is pressed, the aluminium wire of spraying is quickly sent out, if
Diameter 0.2mm silk material 500m/s are put,；Particle rapidity 386m/s, voltage 32-34V, electric current 160-200A, air pressure atomization
0.5-0.6MPa, spray gun is with part apart from 155-175mm, and angle is 45 °；Wire-feed motor rotates wire feed when 3. pressing Switch of spray pistol,
Sprayed；
