Background technology
Ceramic gold-halogen lamp is one of state-of-the-art energy-conserving light source in the current whole world, it has the advantages such as light efficiency is high, the life-span is long, colour rendering is good, compact conformation, being widely used in the indoor and outdoor lighting such as airport, harbour, road, market, hotel, is one of optimal light source.The shell of ceramic gold-halogen lamp (alumina ceramic tube) is the critical component of making ceramic gold-halogen lamp.The alumina ceramic tube of slip casting method single type, reason has also limited large-scale production because the volume of cavity is difficult to control, and dimensional uniformity is poor, and efficient is low etc.The single type machine presses sinter molding method manufacture craft very complicated; from prescription → ball milling → mist projection granulating → reinforced (in mould, putting into first one with the wax ball of core bar before the reinforced) → compacting → demoulding → depoling bar → de-waxing → biscuiting → polishing → sintering → cutting → cleaning → check → finished product; its moulding is very difficult, thereby restricted the production of industrialization, scale.Particularly this alumina ceramic tube because the fluctuation of feeding quantity and ram-jolt density can cause a lot of defectives to product, makes the rate of manufacturing a finished product low in the quantifying feed process.
Summary of the invention
Technical problem to be solved in the utility model provides device reinforced in a kind of alumina ceramic tube preparation process, and apparatus structure is simple, accurate measurement, and even density from improving product percent of pass, is conducive to large-scale industrial production.
The technical scheme that technical solution problem of the present invention adopts is: the device that feeds in raw material in a kind of alumina ceramic tube preparation process comprises bracing frame, quantitative discharging device, conveying device, controller and starting switch; Described quantitative discharging device is arranged at bracing frame one side, described quantitative discharging device is provided with successively from top to bottom transition storage cavity, Quantitative dosing chamber, adjusting nut and is with valvular cylinder two, described transition storage cavity one side is provided with cylinder one, and described quantitative discharging device top connects storage vat; Described conveying device is arranged at the below of quantitative discharging device, and described conveying device comprises the rail groove of dither and delivery mold.
As further improvement, described Quantitative dosing chamber by the cylinder of outside and inner be provided with conical funnel and surround with the cylinder of tremie pipe consist of, the top in described Quantitative dosing chamber is cylindrical shape, the bottom is conical funnel.
As further improvement, described rail groove has certain gradient.
A kind of method of feeding in raw material such as above-mentioned device of using is as follows:
The first step adds the powder of having finished mist projection granulating in storage vat, the powder of the storage vat four/three volumes of generally packing into maybe can be for the requirement of 1000 blank formings;
Second step is pressed starting switch, and the powder in the storage vat is discharged in the transition storage cavity, generally is discharged into 2~3 times of powders of the required powder of molding blank;
The 3rd step, in case of necessity, adjust as required the powder capacity in Quantitative dosing chamber by regulating adjusting nut, then produce displacement by cylinder one control transition storage cavity, make the powder in the transition storage cavity be discharged into the Quantitative dosing chamber; Perhaps directly produce displacement by cylinder one control transition storage cavity, make the powder in the transition storage cavity be discharged into the Quantitative dosing chamber; The powder that is discharged into should be concordant with the upper surface in Quantitative dosing chamber;
The 4th step, by cylinder two control institute with valve, make the powder in the Quantitative dosing chamber be discharged into the mould that places rail groove interior;
The 5th step, place mould in the rail groove at dither with 10H
Z~25H
ZBetween the vibration of vibration frequency under be moved into the terminal storeroom of rail groove, the powder in the mould distributes and is tending towards even simultaneously; Then cover the end socket of mould.
The utility model is applicable to the preparation of the ceramic gold-halogen lamp usefulness alumina ceramic tube of 20w~2000w.
The utility model will spray does the good powder of granulation, puts into fixing main storage vat, sends the blanking command signal according to controller, makes the powder of q.s flow into the transition storage cavity, to guarantee not produce because of gravity between powder the inhomogeneities of density; Send instruction according to controller again the powder of blank forming needs is sent into the Quantitative dosing chamber, in powder was packed mould at last, the mould of filling quantitative powder moved while shaking in oscillating trough, until mold movement is to the storeroom of standby pressure.Among the present invention, the Quantitative dosing chamber by the cylinder of outside and inner be provided with conical funnel and surround with the cylinder of tremie pipe consist of, its top is cylindrical shape, the bottom is conical funnel.By regulating adjusting nut, adjustment is provided with cylinder present position in cylinder of conical funnel, make the lifting of conical funnel cavity with the height of change top cylinder shape cavity, thus the volume size in adjustment quantitative blanking chamber, i.e. the amount of the powder that adjustment adds.
The beneficial effects of the utility model are: adopt quantitative automatic vibrations reinforced; replace hand charge; solved the problem of powder weighing fluctuation; base substrate weight is consistent; even density, good product consistency has improved quality and the qualification rate of product; reduce the waste of powder, be conducive to large-scale industrial production.
