Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
In FERRITE CORE manufacturing process, need through operations such as powder process, compacting, sintering.Before compressing, need to carry out apparent density measurement to the powder that the powder process stage makes, apparent density refers to that powder is under rated condition, is freely full of after volumetric standard measured bulk density, the i.e. quality of unit volume during the loose filling of powder.Apparent density is the important parameter in FERRITE CORE manufacturing process, and this is because apparent density is too high, causes the FERRITE CORE product strength that makes low, frangible; Apparent density is too low, causes ejection resistance to strengthen, easily delamination splitting.
As Fig. 1, a kind of magnetic apparent density of the utility model measurement mechanism, comprises the quantitative pot 4 that volume is known, and quantitative pot 4, for determining the volume of powder, adopts quantitative pot 4 to determine that the method for powder volume is accurate and simple and easy to do; Quantitative pot 4 is placed in above base station 1, there are funnel 3 and discharging opening 5 thereof in quantitative pot 4 tops, funnel 3 is connected by measurement bay 2 with base station 1, funnel 3 is for storing the powder that is about to fall to entering quantitative pot 4, discharging opening 5 is the outlet of the powder in quantitative pot 4, the design of funnel 3 and discharging opening 5 thereof can make powder slowly and at the uniform velocity fall into quantitative pot 4, be convenient to the powder that in quantitative pot 4, powder can stop after filling in funnel 3 timely and continue to fall, base station 1 is convenient to the placement of quantitative pot 4; The utility model also comprises electronic balance and try square, quality when electronic balance is filled powder for measuring the quality of quantitative pot 4 and quantitative pot 4, use the simple to operate and accurate of electronic balance measurement quality, try square is for scraping off the powder that quantitative pot 4 is piled up above, powder is flushed with the mouth of quantitative pot 4, accurate to guarantee that powder apparent density is measured.
The operation steps of a kind of magnetic apparent density of the utility model measurement mechanism is as follows:
Before operation, first by funnel 3, quantitative pot 4 wiped clean;
Quality with the weighed measuring tank 4 of electronic balance;
Unclamp hand, the powder in funnel 3 is fallen into quantitative pot 4 through discharging opening 5;
Or, directly in quantitative pot 4, pour powder into, after powder in quantitative pot 4 falls completely, with try square, scrape off the powder of piling up on quantitative pot 4, powder is flushed with the mouth of quantitative pot 4;
Finally, use the quality of the weighed measuring tank 4 of electronic balance and powder;
The difference of former and later two quality is compared with the known volume of quantitative pot 4, is the apparent density of powder.
Above-mentioned electronic balance is replaceable is other known weighing device, as spring balance.
Above-mentioned try square is replaceable for having other instrument of plane or straight line, as scraper plate.
Above-mentioned quantitative pot 4 is replaceable is the container that other volume is known, as quantitative box, volumetric bottle.
Above-mentioned discharging opening 5 places are provided with the thin slice with sealing use for opening, thin slice and funnel 3 are riveted together, thin slice can relatively rotate with funnel 3, when reinforced to quantitative pot 4, by thin slice turn-off, allow powder flow out from discharging opening 5, after powder in quantitative pot 4 falls completely, thin slice is gone back to discharging opening 5 belows, discharging opening 5 is sealed, stop powder.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
