In addition, the insolated structure of the treatment tank and the liquid nitrogen container is characterized in that the insolated structure has wide application range, and low processing cost, with the processing parameter set according to the material of different workpieces, so as to reach the best treatment effect.
Description
Technical field
The utility model relates to a kind of deep hypothermia that utilizes material is carried out the device that modification is handled, and especially relates to a kind of device that the metal tool and mould is carried out sub-zero treatment.
Background technology
The sub-zero treatment of so-called material utilizes heat-eliminating medium exactly, and material cooled to certain low temperature, is kept returning to room temperature after the regular hour in low temperature, the method that the over-all propertieies such as wear resistance, erosion resistance of material are improved.For metallic substance, its sub-zero treatment is exactly that process of cooling with the metallic substance after quenching continues, reach a certain temperature far below room temperature, existing residual austenite further is converted into martensite after impelling conventional thermal treatment, improve and the thinning microstructure structure, strengthen tool and mould wear resistance and dimensional stability, improve the metallic substance performance.These materials are in the conventional quenching process, and martensitic transformation final temperature is mostly below 0 ℃, have in addition reach-110 ℃.Therefore, this class material will stay residual austenite behind conventional quenching, and its content reaches 13-45% sometimes, thereby has limited the raising of material hardness and wear resistance.The austenite of material is a process with volumetric expansion to martensitic structural transformation, and this process duration is very long, usually needs the time of several years, and this brings instability on the shape and size precision for the metal precision part.Through sub-zero treatment, can improve the wear resistance of part, and prevent from preserving and changing the dilatational strain that martensite brings into because residual austenite is decomposed between the usage period, this is particularly important for cutter, cutlery, tool and mould, tight device etc.In the process of sub-zero treatment, the uniformity of its rate temperature change and whole workpiece temperature is vital.At present, existing cryogenic treatment apparatus generally all is workpiece to be placed in the container of splendid attire liquid nitrogen carry out direct immersion treatment, or liquid nitrogen spray carried out subzero treatment to the surface of workpiece, the disadvantage that adopts this device that workpiece is handled is to cause the workpiece surface corrosion easily, temperature variation is inhomogeneous to damage the workpiece weave construction, and the consumption of temperature control difficulty and liquid nitrogen is too big.
The utility model content
When handling workpiece in order to overcome existing cryogenic treatment apparatus, its whole workpiece temperature variation fluctuation is big, the deficiency that temperature distributing disproportionation is even, it is stable that technical problem to be solved in the utility model provides in a kind of workpiece treating processes temperature variation, the tool and mould cryogenic treatment apparatus that bulk temperature is evenly distributed.
The technical scheme that its technical problem that solves the utility model adopts is: the tool and mould cryogenic treatment apparatus comprises being arranged on the intravital cooling vessel of cabinet, liquid nitrogen container and the liquid nitrogen pump that is connected cooling vessel and liquid nitrogen container.The top of cooling vessel is provided with top cover, is provided with treatment tank in the cooling vessel, and treatment tank is provided with cover.Utilize liquid nitrogen pump to control and determine for what of amount of liquid nitrogen, be the treatment temp of workpiece in the may command treatment tank and the speed of variation, and owing to workpiece does not directly contact with liquid nitrogen, thereby make the treatment temp of workpiece reach unanimity, reach the purpose that bulk temperature is evenly distributed.
The beneficial effects of the utility model are, because the mode that has adopted workpiece in the treatment tank directly not contact with liquid nitrogen, make the treatment temp of workpiece reach unanimity and control easily; By to for the control of amount of liquid nitrogen, i.e. the treatment temp of workpiece and the speed of variation in the may command treatment tank.By sub-zero treatment, can make the residual austenite of workpiece is martensite at comparatively ideal temperature range fundamental transformation.After testing, the residual austenite of the workpiece after the sub-zero treatment only deposits 1～5%, and its transformation efficiency reaches 90～100%, and for the steel grade of carbon content＜0.3～0.4%, sub-zero treatment can realize the transformation of residual austenite more than 96%.Metallic substance causes that not only residual austenite decomposes after sub-zero treatment, and martensite partly decomposes, and changes carbide into, separates out with the dislocation form subsequently, and forms the submicroscopic carbide, and micro-viscous deformation takes place.Find that by electron microscopic observation the lath martensite fragmentation is the matrix refinement, carbide refinement.Here it is in the sub-zero treatment process, not only has residual austenite to change, and also have fine carbide to separate out and the structure refinement process.Adopt the type of cooling of indirect type, can also well protect the quality and the treatment effect of processed workpiece, and can make treatment temp more stable, processing accuracy is higher.That the isolated structure of above-mentioned treatment tank and liquid nitrogen container also has is applied widely, processing cost is low, can set corresponding treatment process parameter according to the material of different workpieces, thereby reaches the characteristics of best treatment effect.
