Abstract
The utility model relates to an arc reinforcing electrochemical deposition device for the surface of aluminium alloy. The device is provided with a shower pipe at the upper part of plating liquid, the circumference of a plating groove is added with a top wind inducing channel and a bottom wind discharging pipe, and the insulation part is added with an insulation pad. By way of the processing of the enhancement of electric arc and electrochemical deposition, the oxidizing processing time of aluminium alloy work pieces can be shortened to 7-15 minutes, and the cost is 1/2-1/3 of the cost of other technology. The arc reinforcing electrochemical deposition device for the surface of the aluminium alloy has the advantages of high work efficiency, little environmental pollution and simple and easy working procedure. The utility model is also suitable for the surface treatment of alloy material, such as titan, niobium, zirconium, etc.
Description
The utility model is related to be that a kind of aluminum alloy surface electric arc strengthens electrochemical depositer.
At present, aluminum alloy material surface is handled and is adopted the anode oxidation process device mostly, adopts the mode of low voltage, big electric current on circuit layout, when its shortcoming is surface treatment, and the pre-treating technology complexity, productivity is low, and environmental pollution is big, and production cost is higher.
The purpose of this utility model is to design a kind of aluminum alloy surface electric arc enhancing electrochemical depositer for overcoming above-mentioned deficiency, be used for replacing the device of anode oxidation process, its surface abrasion resistance of aluminum alloy materials, corrosion resistance excellent after electric arc strengthens the electrochemical depositer processing, coating quality is stable, color even is consistent, keeps color and luster constant in the use.By the prescription of allotment plating bath, can obtain white, oyster white, coffee color, grey, Lan Se and 20 multiple color tones such as bronze-colored, also can carry out chromatography and handle it.
Content of the present utility model is on the top of plating bath shower to be arranged, and is added with top wind channel and bottom exhaust duct around the coating bath, is added with insulating mat in the insulated part.Whole apparatus structure compactness makes that the Al alloy parts lifting is convenient, helps the discharging of hydrogen, non-environmental-pollution.
What the utility model was implemented is a kind of arc discharge enhanced electrochemical treatment technology, and the high density energy of utilizing arc discharge to have excites and intensified response, obtains the rete of similar ceramic character on the Al alloy parts surface.Owing on circuit layout, adopt the mode of high-voltage, big electric current, therefore reduced pre-treating technology.Compare with the anode oxidation process device, the utility model has improved the working (machining) efficiency and the treatment effect of common oxidation widely, the work efficiency height, and cost is low.For example strengthen the piston of automobile that electrochemical depositer is handled through this electric arc, be loaded on the automobile 75000 kilometers of operations after, piston does not still have the carbon deposit phenomenon, and oil consumption reduces.The working ability of this device butt welded seam, hole is strong.
Fig. 1 is a front view of the present utility model
Fig. 2 is a vertical view of the present utility model
Fig. 3 is the utility model A-A side cross-sectional view
Below in conjunction with accompanying drawing the utility model is described in further detail.
Electric arc strengthens electrochemical depositer and is loaded in the coating bath of being made up of coating bath shell 11, support foot 12, negative plate 8 and insulcrete 10 with plating bath 3.Insulating mat 7 and insulcrete 10 are formed insulated part, and negative plate 8 and ground insulation resistance are reached more than the 5M Ω.Insulating mat 7 is garden shape, and thickness is between 20～40 millimeters, and diameter is between 100～150 millimeters.The shape of negative plate 8, insulcrete 10 is consistent with the shape of coating bath shell 11.Shower 2 has several apertures in the form of a ring as nozzle on it, plating bath 3 is via the ejection of the nozzle on the shower 2 cooling.Loop hose 1, shower 2, recycle pump 13 and the water cooler 14 common cooling segments of forming its role is to plating bath 3 is controlled in certain temperature.Top wind channel 5, induced draft fan 6 and bottom exhaust duct 15 common formation air draft parts.Top wind channel 5 is communicated with bottom exhaust duct 15, bottom exhaust duct 15 rectangular connections and being communicated with induced draft fan 6 again.Its effect is that the hydrogen that aluminum alloy materials is produced when electric arc strengthens electrochemical deposition is in time emitted, with blast protection.
During work, at first start recycle pump 13 and water cooler 14, plating bath 3, returns by in the coating bath of being made up of coating bath shell 11, support foot 12, negative plate 8 and insulcrete 10 by several nozzle ejections on the shower 2 through recycle pump 13 loop hoses 1.Play the dual function that makes plating bath 3 coolings and evenly stir like this.Between the negative electrode and Al alloy parts 9 formed by negative plate 8, cathode rod 4, on Al alloy parts 9, produce arc discharge owing to feed high-voltage, big electric current, consequent hydrogen is overflowed from plating bath 3 surfaces, and it is guided at a distance by induced draft fan 6 through top wind channel 5, bottom exhaust duct 15 and to emit, the general work time is can finish in 7～15 minutes, and cost is 1/2～1/3 of other technology cost.Al alloy parts 9 is taken out, close recycle pump 13 and water cooler 14, turn off induced draft fan 6 at last, finished whole process.
The utility model is equally applicable to the surface treatment of alloy materials such as titanium, niobium, zirconium.
