Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
See Fig. 2 and 3, the spreading out device that the utility model provides is covered in the opening part of crucible 2.Spreading out device comprises guide rail, scraping mechanism, handle 3.Handle 3 is fixedly connected on scraping mechanism.Move under the effect of the power that scraping mechanism can apply along guide rail at handle 3.
In one embodiment, scraping mechanism is by being arranged on the orbital motion on guide rail.Now the inner edge of guide rail is concordant with the inwall of crucible 2.
Guide rail can be different according to the shape difference of crucible 2 used.Guide rail comprises at least two guide rods be oppositely arranged, and any two relative guide rods are arranged in scraper structure, and scraping mechanism can move along two relative to guide rod.In this embodiment, guide rail is fixed on the opening part of crucible 2.Guide rail inwall arranges guide-track groove, and the two ends of material scraping plate 4 are connected in stem guiding trough.As when crucible 2 is shape changeable, after material scraping plate 4 has moved between guide rod any two.Again insert after can manually being taken out in the guide-track groove of other any two relative guide rods, slide along guide-track groove.Thus complete effect is shakeout to powder in crucible 2 comprehensively.The number of preferred guide rod is equal with the limit number of crucible 2.
In one of them preferred embodiment, guide rail is finished up to connect by the first guide rod 10, second guide rod 11, the 3rd guide rod 12 and the 4th guide rod 13 and surrounds rectangle.On scraping mechanism, symmetry offers two installing holes, and the second guide rod 11 and the first guide rod 10 are each passed through two installing holes.Thus scraping mechanism can be moved along guide rail.
Lack the strong point during in order to prevent from shakeouing, at least two support bars occurred in pairs are set in the periphery of guide rail.Support bar abuts on the outer wall with crucible 2.
In one of them preferred embodiment, support bar comprises the first support bar 111, second support bar 101, the 3rd support bar 112 and the 4th support bar 131.The joining place of the second guide rod 11 and the 3rd guide rod 12 is fixed in one end of first support bar 111, and the other end extends along crucible 2 outer wall to the bottom of crucible 2.
One end of second support bar 101 is fixedly connected on the joining place of the 3rd guide rod 12 and the first guide rod 10.The other end of the second support bar 101 extends bottom crucible 2 along crucible 2 outer wall.One end of 3rd support bar 112 is fixedly connected on the joining place of the second guide rod 11 and the 4th guide rod 13.The other end of the 3rd support bar 112 extends bottom crucible 2 along crucible 2 outer wall.One end of 4th support bar 131 is fixedly connected on the joining place of the 4th guide rod 13 and the first guide rod 10, and the other end extends bottom crucible 2 along crucible 2 outer wall.
The interior contact of the moveable and crucible 2 of the outer rim of scraper structure.
In order to improve operating efficiency, be the rectangular material scraping plate 4 of strip or s type see the preferred scraping mechanism of Fig. 3.Be preferably strip material scraping plate 4.Now scraper effect reaches optimum.
In another preferred embodiment, the bottom surface that scraping mechanism contacts with powder is evenly provided with multiple sawtooth 41, sawtooth 41 respectively to its institute's powder that contacts force, can make powder shakeout process more even, reduces the too high problem of local accumulation density and occur.
During use, the scraping mechanism being equipped with guide rail is installed on the opening part of crucible 2.Support bar is connected on the outer wall of crucible 2.By manipulation handle 3, scraper structure is moved to the other end from one end of guide rail.Can complete and once shakeout operation.
See Fig. 4 ~ 6, the difference of another embodiment of the present utility model and previous embodiment is: scraping mechanism comprise two can mutually against the first material scraping plate 42 and the second material scraping plate 43.Handle 3 comprises the first in command 31 and the second in command 32.The first in command 31 is connected with the first material scraping plate 42.The second in command 32 is connected with the second material scraping plate 43.See Fig. 4 and Fig. 5, the first in command 31 one end is fixedly connected on the end face of the first material scraping plate 42.The first in command 31 is identical with the structure of the second in command 32, is only described in detail to the first in command 31 below, the second in command 32 can the like.
Second end Vertical dimension first material scraping plate 42 extension of the first in command 31, forms extension.Top bending follow-up the continuing of extension extends to form kink.Kink is preferably perpendicular to extension.The extension of the first in command 31 transversely runs through extension and forms first longitudinal holding hole 311.The kink longitudinally through kink formation first of the first in command 31 laterally holds hole 312.Holding hole by arranging two, making handle 3 be convenient to when operating control, after having shakeout, the holding hole being positioned at kink can be utilized to unload from crucible 2 easily.
On first material scraping plate 42, two installing holes are offered at interval; On second material scraping plate 43, another two installing holes alignd with the installing hole on the first material scraping plate 42 are offered at interval.Thus make the guide rod in guide rail can pass the same position of the first material scraping plate 42 and the second material scraping plate 43 simultaneously.Keep the first material scraping plate 42 and the second material scraping plate 43 can keep balance in moving process, and be unlikely to occur distortion.
The number of obvious material scraping plate 4 is not limited to two, also can be multiple.Consider Cost Problems, be preferably two material scraping plates 4.
The utility model additionally provides a kind of crucible 2 containing above-mentioned spreading out device on the other hand.This crucible 2 can contain this spreading out device when selling, and wherein can comprise the operation instruction of spreading out device, to make user clear and definite, after use crucible 2 is reinforced, shakeouts with it, is removed by spreading out device before entering sintering furnace.
The spreading out device that the utility model provides is particularly useful for rectangle crucible 2.Now the motion path of scraping mechanism is the shortest, and contact powder area is maximum.Preferred above-mentioned spreading out device adopts the macromolecular materials such as PP plastics to make, and thus can not introduce other metal impurities in powder, and spreading out device lighter in weight, the pressure produced powder at the initial stage of installation is also less.After shakeouing, spreading out device is removed, advanced by the crucible 2 that powder is housed pushed bat kiln or roller kilns sintering to obtain product afterwards.
The spreading out device adopting the utility model to provide can prevent from shakeouing in process, and powder local accumulation density is excessive, affects follow-up sintering effect.Simultaneously easy to operate, operating efficiency is improved.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
