Description
Technical field
The present invention relates to the preparation facilities of film coating, especially a kind of thickness adjustable film coating preset mechanism.
Background technology
Before doing material surface Alloying Treatment, it is generally required to coat certain thickness powder coating in base metal surface, then with related process, coating surface is processed, make coating and matrix form modified layer between the two, reach the purpose of strengthening surface performance.
Plasma spray technology is that a kind of feeding by coating material (powder or silk material) in certain thermal source (electric arc, combustion flame, plasma etc.) is melted, and utilizes high velocity air to be injected into the technique that substrate material surface forms coating.Hot-spraying coating has the premium properties such as wear-resistant, corrosion-resistant, high temperature resistant and heat insulation.According to the thermal source used, plasma spray technology is divided into plasma spraying, flame-spraying and electric arc spraying etc..It is thermal source that plasma spray is coated with plasma arc；Flame-spraying is with gas flame as thermal source；Electric arc spraying is with electric arc as thermal source.Plasma spray technology is widely used in Surface Technics field, occupies very important position in preparation and the product remanufacturing field of composite coating.But plasma spray technology cost is high, complex operation, requiring powder size strict, coating layer thickness is difficult to accurately control.
Plasma arc temperature is up to 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, may be by plasma spraying technology and forms coating.Relative to other surface spraying technology, coating morphology compact, crackle that plasma spraying technology is formed are less.Flame-spraying is divided into detonation flame spraying and thermal-flame spraying, is mainly characterized by flame Flow Velocity fast, and the coating of formation is high with substrate combinating strength.Electric arc spraying is to utilize the electric arc burnt between two tinsels being continuously fed to melt metal, with high velocity air, molten metal is atomized, and accelerates to make them spray to the technology of workpiece formation coating to the metallic of atomization.Electric arc spraying is a kind of heat spraying method commonly used most in the practical application engineering such as steel structure anti-corrosion, wear-resistant and machine components maintenance.
But plasma spray technology cost is high, and coating layer thickness cannot accurately control.Some refractory metal powder material, needs the highest temperature, the most thousand of degrees Celsius, matrix surface so will certainly be made to melt, produce residual stress, form certain thickness modified layer during thermal spraying.But, require when we do material surface alloying research that coating and matrix are preferably mechanical bond, if the coating of thermal spraying and matrix define metallurgical binding, the research of material surface alloying special process will be affected.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, and a kind of thickness adjustable film coating preset mechanism is provided, it is front to carrying out the preset of coating on matrix that mechanism is mainly used in portion of material processing, the thickness of coating can be accurately controlled by mechanism by demand, easy to operate, press mold process stabilization, topology layout is reasonable, and efficiency is high.
The technical scheme realizing the object of the invention is:
A kind of thickness adjustable film coating preset mechanism, including
Location upper mold and location lower mold, the lower surface of described location upper mold is provided with upper mold groove, and the upper surface of location lower mold is provided with lower mold groove, and location upper mold is fixed by bolt with location lower mold, upper mold groove formation press mold corresponding with lower mold groove chamber；
Workbench, described workbench is arranged in lower mold groove, and workbench is rotatably connected with thickness adjusted bolt, and the adjustable side of thickness adjusted bolt passes lower mold lower surface, location, and thickness adjusted bolt is spirally connected with location lower mold；
Press mold dish, described press mold dish is arranged in upper mold groove, and press mold dish is rotatably connected with hold-down bolt, and the adjustable side of hold-down bolt passes upper mold upper surface, location, and hold-down bolt is spirally connected with location upper mold.
The area of described press mold dish lower surface is more than the area of workbench upper surface.
The lower mold groove upper surface of described location lower mold is provided with discharge groove.
Described discharge groove is 2-10, and preferably 4, equal decile arranged distribution is on the upper surface of lower mold groove.
Mechanism being used for portion of material processing front to carrying out the preset of coating on matrix, use waterglass as binder metal powder, make coating and matrix realize mechanical bond, low cost, without residual stress.Plasma spray technology spray-on coating typically used by some materials such as metal of the prior art, but owing to thermal spraying cost is high, coating layer thickness is difficult to be accurately controlled.Mechanism can realize the molding of different-thickness thin film by controlling thickness adjusted bolt, can be accurately controlled the thickness of coating by demand, easy to operate, press mold process stabilization, and topology layout is reasonable, and efficiency is high.

Detailed description of the invention
With embodiment, present invention is further elaborated below in conjunction with the accompanying drawings, but is not limitation of the invention.
Embodiment:
With reference to Fig. 1, a kind of thickness adjustable film coating preset mechanism, including
Location upper mold 6 and location lower mold 5, the lower surface of described location upper mold 6 is provided with upper mold groove, and the upper surface of location lower mold 5 is provided with lower mold groove, and location upper mold 6 is fixed by bolt with location lower mold 5, upper mold groove formation press mold corresponding with lower mold groove chamber；
Workbench 2, described workbench 2 is arranged in lower mold groove, and workbench 2 is rotatably connected with thickness adjusted bolt 1, and the adjustable side of thickness adjusted bolt 1 passes lower mold 5 lower surface, location, and thickness adjusted bolt 1 is spirally connected with location lower mold 5；
Press mold dish 8, described press mold dish 8 is arranged in upper mold groove, and press mold dish 8 is rotatably connected with hold-down bolt 9, and the adjustable side of hold-down bolt 9 passes upper mold 6 upper surface, location, and hold-down bolt 9 is spirally connected with location upper mold 6.
The area of described press mold dish 8 lower surface is more than the area of workbench 2 upper surface.
With reference to Fig. 2 Fig. 3, the lower mold groove upper surface of location lower mold 5 is provided with discharge groove 5-1.Discharge groove 5-1 is 2-10, and in Fig. 2 Fig. 3, discharge groove 5-1 is four, is evenly distributed on the upper surface of lower mold groove.
When the area of press mold dish 8 lower surface is to allow press mold dish 8 be pressed in the lower mold 5 of location more than the area of workbench 2 upper surface, make the metal dust being mixed with sodium silicate binder unnecessary between press mold dish 8 and the workpiece being on workbench 2, the discharge groove 5-1 of lower mold 5 lower mold groove upper surface, location discharge.
