Abstract
The utility model discloses a kind of powder metallurgy die cover half with lubricating arrangement and mould, cover half has inner molding cavity, cover half is provided with lubricating arrangement, lubricating arrangement comprises oil nozzle, oil guide pipe and drip ring, oil nozzle is on cover half surface, drip ring is arranged on molding cavity sidepiece, and oil guide pipe is positioned at cover half inside, connects oil nozzle and drip ring.The wearing and tearing substantially reduced between the cover half of powder metallurgy die and drift of the present utility model, extend the mold use life-span, improve the quality of product blank.
Description
Technical field
The utility model belongs to powder metallurgy die manufacturing technology field, is specifically related to a kind of powder metallurgy die cover half with lubricating arrangement and mould.
Background technology
Powder metallurgy be produce metal dust or with metal dust (or mixture of metal dust and non-metal powder) as raw material, through shaping and sintering, produce the industrial technology of metal material, composite and all kinds goods.PM technique possess significantly energy-conservation, economize the high and series of advantages such as good stability of material, excellent performance, Product Precision, be very suitable for producing in enormous quantities.In addition, the material that part conventional casting methods and machining process cannot be prepared and complex parts also available powders metallurgical technology manufacture, thus enjoy the attention of industrial quarters.
In forming process, powder easily fall into the cover half of mould and drift fit clearance in, cause the ejection resistance of mould become large or damage, thus cause defective products.Existing powder metallurgy die fixed mould structure schematic diagram as shown in Figure 1, does not have lubricating arrangement powder long time integration thus the wearing and tearing added between mould and ejection resistance, has had a strong impact on the quality of product pressed compact.
Utility model content
For the deficiency that prior art exists, the utility model provides a kind of powder metallurgy die cover half with lubricating arrangement, and the lubrication increased between mould improves the quality of product pressed compact.
The technical solution of the utility model is as described below: a kind of powder metallurgy die cover half with lubricating arrangement, cover half has inner molding cavity, it is characterized in that, cover half arranges lubricating arrangement, described lubricating arrangement comprises oil nozzle, oil guide pipe and drip ring; Oil nozzle is arranged on cover half surface, and drip ring is arranged on molding cavity sidewall, and oil guide pipe is positioned at cover half inside, connects oil nozzle and drip ring.Preferably, drip ring internal diameter is identical with the diameter of molding cavity, and the axis of the two is identical.Described lubricating arrangement principle is for inject lubricating oil by oil nozzle, drip ring is entered through oil guide pipe, lubricating oil penetrates into the sidewall of the molding cavity of mould by the micropore in drip ring, add the lubrication between cover half and drift thus reduce wearing and tearing, improve the quality of product pressed compact.
Drip ring can be made up of porous metal material, and preferably, drip ring is made up of porous mold steel.
Preferably, the height of drip ring is 2-10mm, is preferably 5-8mm.When the thickness of drip ring is 2-10mm, can ensure good lubricant effect, the unlikely intensity to molding cavity sidewall produces considerable influence again.
Further, described drip ring be arranged at molding cavity 20%-50% At The Height.At this At The Height, molding cavity sidewall and low punch are lubricated.Because metal dust under gravity, drops in the fit clearance of molding cavity sidewall and low punch.
Further, the position of described drip ring is at molding cavity 30% At The Height.
Further, the quantity of oil nozzle and oil pipe is 2-4.The quantity of oil pipe and oil nozzle is equal, and the link position of oil pipe and drip ring is equidistantly distributed.Under the quantity of oil nozzle and oil pipe is 2-4 situation, good lubricant effect can be ensured, be unlikely to again because lubrication is oozed out too much and increase cost.
In addition, the utility model provides a kind of powder metallurgy die with lubricating arrangement, and it comprises the above-mentioned powder metallurgy die cover half with lubricating arrangement, upper punch and low punch.
The beneficial effects of the utility model are: by arranging lubricating arrangement on the cover half of powder metallurgy die, decreasing the wearing and tearing between cover half and drift, extending the mold use life-span, improve the quality of product blank.

Detailed description of the invention
Now by reference to the accompanying drawings 2, Fig. 3 further describes the utility model, but these explanations are only illustration, and the utility model is not by the restriction that these illustrate.
Fig. 2 shows the generalized section of the powder metallurgy die cover half with lubricating arrangement of the present utility model, cover half has inner molding cavity 4, it arranges lubricating arrangement on the cover half of traditional powder metallurgy die, and lubricating arrangement comprises oil nozzle 1, oil guide pipe 2, drip ring 3.Oil nozzle 1 is arranged on cover half surface, and drip ring 3 is arranged on molding cavity 4 sidewall, and drip ring 3 internal diameter is identical with the diameter of molding cavity 4, and the axis of the two is identical, and oil guide pipe 2 is positioned at mould inside, connects oil nozzle 1 and drip ring 3.Lubricating oil injects by oil nozzle 1, then delivers to drip ring 3 through oil guide pipe 2, and drip ring 3 is made up of porous metal material, therefore, it is possible to be seeped on molding cavity 4 inwall by lubricating oil by the micropore of self.
Fig. 3 is the generalized section of the powder metallurgy die with lubricating arrangement.In the process of upper punch 6, low punch 7 cover half pressed blanks 5, powder falls in the fit clearance of cover half and low punch 6, powder long time integration adds the wearing and tearing between mould, lubricating oil is seeped on molding cavity 4 inwall by the micropore of self by drip ring 3, thus increase the lubrication of molding cavity 4 sidewall and drift (being low punch 6 in the present embodiment), reduce the wearing and tearing between cover half and low punch 6, thus extend the mold use life-span, improve the quality of product blank 5.
Preferably, drip ring 3 is made up of porous mold steel.
Preferably, the thickness of drip ring 3 is 3-10nm, more preferably 5-8mm.
Preferably, 20%-50% At The Height being arranged at molding cavity 4 of described drip ring 3, more preferably 30% At The Height.
