Description
Technical field
The present invention relates to a kind of nickel chromium triangle composite plating safety guard, belong to hydro-cylinder field of electroplating.Be particularly suitable for the protection of excavator hydraulic cylinder piston rod nickel chromium triangle composite plating.
Background technology
When often occurring in the excavator cylinder piston rod course of processing needing plating position to have again a position that can not electroplate to same workpiece is existing, protection must be carried out the position that can not electroplate and isolate, as excavator hydraulic cylinder piston rod nickel chromium triangle composite plating.
At present, traditional plating safety guard often uses the metallic substance such as iron and steel to make or is wrapped in adhesive plaster does not on the one hand need the position of electroplating to protect, or use the materials such as PP to make, the weak point of these safety guards is: reusing is poor, not easy cleaning, complicated operation, easily to bath solution pollution etc.PVC material is generally used to design and produce by protective coat for current piston rod nickel chromium triangle composite plating safety guard on the other hand, protective ring, protective shield forms, fixed by bolt and piston rod, the threaded hole position of protective coat is designed according to piston rod construction difference, this kind of safety guard has the following disadvantages: one is that protective coat kind is too many, quantity large, and different model workpiece can not be general, and cost is too high; Two install when being and using and dismounting inconvenient, complicated operation is time-consuming, and need torque spanner could fix with workpiece, safety guard easily tilts and comes off; Three is easily be detained tank liquor, forms crossed contamination, affect quality product between bath solution.
Summary of the invention
The invention provides a kind of application convenient, reusing is good, reduces the crossed contamination between bath solution, the nickel chromium triangle composite plating safety guard that protection effect is good.
The present invention realizes with following technical scheme, a kind of nickel chromium triangle composite plating safety guard comprises protective coat, the protection inner sleeve that have end cap of device in protective coat one end, the protection external diameter of inner sleeve and the minor diameter fit of protective coat, internal diameter coordinates with cylinder piston rod; Described protective coat is step pipe, and the step of protective coat one end is provided with overcoat outage; In protection, cover is provided with inner sleeve outage and sump pit, described protection inner sleeve and protective coat are combined by bolt; Protection inner sleeve inwall has interior external threading, and whole safety guard is fixed on cylinder piston rod non-electroplating part by the interior external threading and piston rod thread protecting inner sleeve.
Nickel chromium triangle composite plating safety guard of the present invention adopts PVC material to make the metallic substance such as safety guard replacement iron and steel and makes or with safety guards such as adhesive plaster windings, first solve reusing difference, not easy cleaning, easily to problems such as bath solution pollute; Secondly in relying on, external threading is fixed on safety guard on workpiece, replaces dependence to be bolted on workpiece, simple to operate, quick when mounting and dismounting, and alleviates the labour intensity of operator, enhances productivity; Three is the workpiece for different model, does not need to redesign to change protective coat, only need change protection inner sleeve, and protective coat can be shared on the workpiece of different model again, reduces cost; Finally, need plate workpiece must protect again position often occur without groove or groove less time, bolt fastening structure not easily blocks firmly, in use easily crooked or come off, and this safety guard can solve, and this is not enough.
Owing to have employed above-mentioned design, it is good, easy to operate simple and convenient that this nickel chromium triangle composite plating safety guard achieves reusing, and saved cost, avoided the crossed contamination between bath solution, protection effect is good, improves production efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is nickel chromium triangle composite plating safety guard schematic diagram of the present invention.
In figure: 1, protective coat, 2, bolt, 3, protection inner sleeve, 3-1, inner sleeve outage, 3-2, sump pit, 4, interior external threading, 5, piston rod.
Embodiment
Embodiment as shown in Figure 1, nickel chromium triangle composite plating safety guard comprises protective coat 1, the protection inner sleeve 3 that have end cap of device in protective coat 1 one end, the protection external diameter of inner sleeve 3 and the minor diameter fit of protective coat 1, and internal diameter coordinates with cylinder piston rod 5; Protective coat is step pipe, and the step of protective coat one end is provided with overcoat outage 1-1; In protection, cover is provided with inner sleeve outage 3-1 and sump pit 3-2, described protection inner sleeve 3 and protective coat 1 are combined by bolt 2; Protection inner sleeve inwall has interior external threading 4, and whole safety guard is fixed on cylinder piston rod non-electroplating part by the interior external threading 4 protecting inner sleeve with workpiece screw thread.
Protective coat 1, bolt 2, protection inner sleeve 3 all adopts PVC material to make, and protection inner sleeve 3 is close to piston rod 5 non-electroplating part surface, and protective coat 1 and protection inner sleeve 3 closely cooperate and be enclosed within piston rod 5 non-electroplating part and play good protection effect.
Adopt PVC material to improve traditional metal guard short for work-ing life, perishable, reusing is poor, and difficult cleaning, installs complicated operation, and metal ion dissolves problems such as tank liquor pollutions.Can reuse with water cleaning after using, simple to operation, cost is low, and reusing is good.Adopt screw connection structure, dismantle and install simple, convenient, working efficiency is high; Acid-alkali-corrosive-resisting, long service life, protection inner sleeve and protective coat are designed with sump pit and outage, and are beneficial to the incline structure of discharge opeing, quick fluid-discharge.On plating automatic line tank liquor is avoided to cause the crossed contamination of electroplate liquid not in time because of discharge opeing; simultaneously; because protection overcoat can be general to Multiple Type cylinder piston rod; only need change protection inner sleeve according to cylinder piston rod helicitic texture can use; due to the erosion resistance of PVC material in high chromium concentration acid solution, and the feature such as the easy to clean of device, reduce cost; decrease cleaning amount, and avoid safety guard pollution to other bath solution is remained to chromic acid solution.
