Description
Technical field
The utility model relates to the preparation facilities of film coating, the film coating preset mechanism that especially a kind of thickness is adjustable.
Background technology
Before doing material surface Alloying Treatment, general needs applies certain thickness powder coating in base metal surface, then processes coatingsurface with related process, makes coating and matrix form modified layer between the two, reach the object of strengthening surface performance.
Hot-spraying techniques is that a kind of feeding by coated material (powder or silk material) in certain thermal source (electric arc, combustion flame, plasma body etc.) is melted, and utilizes high velocity air to be ejected into the technique of substrate material surface formation coating.Hot spray coating has the premium propertiess such as wear-resistant, corrosion-resistant, high temperature resistant and heat insulation.According to used thermal source, hot-spraying techniques is divided into plasma spraying, flame plating and electric arc spraying etc.It is thermal source that plasma spray is coated with plasma arc; Flame plating take gas flame as thermal source; Electric arc spraying take electric arc as thermal source.Hot-spraying techniques is widely used in Surface Technics field, occupies very important position in the preparation of compound coating and product remanufacturing field.But hot-spraying techniques cost is high, complex operation, require strict to powder size, coat-thickness is difficult to accurate control.
Plasma arc temperatures as high more than 10000 DEG C, almost can melt all solids material, and be widely used value, as long as have the material of physics fusing point, plasma spraying technology can be utilized to form coating.Relative to other surface spraying technology, the coating morphology compact that plasma spraying technology is formed, crackle are less.Flame plating is divided into detonation flame spraying and thermal-flame spraying, and principal feature is that flame Flow Velocity is fast, and coating and the substrate combinating strength of formation are high.Electric arc spraying utilizes the electric arc burnt between two wires sent to continuously to come deposite metal, with high velocity air, molten metal is atomized, and accelerate to make them spray to the technology of workpiece formation coating to the metallics of atomization.A kind of heat spraying method the most generally used in the practical application engineering such as electric arc spraying is steel structure anti-corrosion, wear-resistant and mechanical component maintenance.
But hot-spraying techniques cost is high, coat-thickness cannot accurately control.Some refractory metal powder material, needs very high temperature during thermospray, even reaches several thousand degrees Celsius, matrix surface so will certainly be made to melt, and produces unrelieved stress, forms certain thickness modified layer.But require coating and matrix preferably mechanical bond when we do the research of material surface alloying, if the coating of thermospray and matrix define metallurgical binding, the research of material surface alloying special process will be affected.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, and the film coating preset mechanism providing a kind of thickness adjustable, mechanism carries out the preset of coating on matrix before being mainly used in portion of material processing, mechanism can control accurately by the thickness of demand to coating, easy to operate, press mold process stabilization, topology layout is reasonable, and efficiency is high.
The technical scheme realizing the utility model object is:
The film coating preset mechanism that thickness is adjustable, comprises
Location patrix and location counterdie, the lower surface of described location patrix is provided with patrix groove, and the upper surface of location counterdie is provided with counterdie groove, and location patrix is fixed by tack bolt with location counterdie, patrix groove formation press mold corresponding with counterdie groove chamber;
Worktable, described worktable is arranged in counterdie groove, and worktable and thickness adjusting bolt are rotatably connected, and the adjustable side of thickness adjusting bolt passes counterdie lower surface, location, and thickness adjusting bolt is spirally connected with location counterdie;
Press mold dish, described press mold dish is arranged in patrix groove, and press mold dish and push bolt are rotatably connected, and the adjustable side of push bolt passes patrix upper surface, location, and push bolt is spirally connected with location patrix.
The area of described press mold dish lower surface is greater than the area of worktable upper surface.
The counterdie groove upper surface of described location counterdie is provided with discharge groove.
Described discharge groove is 2-10, and be preferably 4, equal decile arranged distribution is on the upper surface of counterdie groove.
Mechanism is carried out the preset of coating on matrix before portion of material processing, and adopt water glass as binder metal powder, make coating and matrix realize mechanical bond, cost is low, without unrelieved stress.Hot-spraying techniques spray-on coating generally used by some materials such as metal of the prior art, but due to thermospray cost high, coat-thickness is difficult to accurate control.Mechanism realizes the shaping of different thickness film by controlling thickness adjusting bolt, can control accurately by the thickness of demand to coating, easy to operate, press mold process stabilization, and topology layout is reasonable, and efficiency is high.
