, Drops to the lower end of the suspended feeder hose 201, and is supplied to the distribution supply unit 5 via the connection unit 35. The flow of the powder falls without staying on the way. Surface 58 receives the flow of the powder. For example, the slope 44 of the conical surface 42, which is one form of the surface 58, ensures that the powder is completely and evenly distributed under the force of the powder flow and the weight of the powder. The powder evenly distributed passes through a feeder hose 202 inserted into six through-holes 46 provided at equal angles from the apex 45 of the conical surface 42 along the inclined surface 44, and is placed on the bottom plate 53 a of the support 53. Hose 20 with the lower end of feeder hose 202 inserted
3, the evenly distributed powder enters the supply section 6. FIG.
, The feeder 1 is connected to the upper surface 18 of the upper plate 14 and the frame 13
The powder advances from the top surface 17 of the die 2 and the upper surface 16 of the die 2 and reciprocates on the upper surface 16 of the die 2, so that the powder drops from the tip end surface 20 of the supply unit 6 in the opening 7 by its own weight and is filled with the filling portion 3 of the die 2. Is filled. When the feeder 1 retreats from the upper surface 16 of the die 2, the upper punch descends and fits into the hole 4, the lower punch 19 rises through the hole 4, and the upper punch and the lower punch 19.
Then, the powder filled in the filling portion 3 is pressed and molded through the hole 4 to obtain a green compact. With reference to FIG. 6, the upper punch then rises, and the lower punch 19 further moves up the filling unit 3 to extract the green compact 60 from the filling unit 3. In a state where the upper punch is lifted and stopped until it is flush with the upper surface 16, before the upper punch rises and separates from the green compact 60, the feeder 1 moves the upper surface 18 of the upper plate 14 of the die plate 12 and the upper surface 17 of the frame die 13. And the upper surface 16 of the die 2 is advanced to fill the filling portion 3 with the next powder. With this advance, the concave groove 30 of the feeder 1 discharges the green compact 60.

す。An experiment was conducted to confirm the effect of the powder feeding device of the present invention. The compacts of the conventional example and the present invention were prepared under the same conditions. That is, as shown in FIG. 10 and FIG. 11, when the external dimensions of the green compact are set to 10.5 mm × 14.9 mm and the molding pressure is set to 156.7 MPa (about 1.6 t / cm 2 ), 100 compacts are continuously formed. A sample was taken for each shot, the weight of the compact was measured, and the variation was determined. In the case of the present invention, as shown in FIG. 1, six dies were arranged in the left-right direction of the die plate, and molding was performed with a setting in which the upper and lower punches pressed 30 times per minute. Calculating this, the time required from molding to dispensing is 2 seconds.
Table 1 shows the results. As a conventional example, three dies are arranged in the front-rear direction of the die plate 12 and two rows in the left-right direction as shown in FIG. Molding was performed under pressure setting. When this is calculated, the time required from molding to dispensing is 3.3 seconds. Table 2 shows the results. As a comparative example, in the powder feeding apparatus of the present invention, powder was supplied without using the distribution supply unit, and molding was performed with the upper and lower punches set to pressurize 18 times per minute. Calculating this, the time required from molding to dispensing is 3.3 seconds. Table 3 shows the results.

Shows the standard deviation. As can be seen from Tables 1 and 2, there was almost no difference in the weight variation of the green compact between the one using the powder feeding device of the present invention and the one using the conventional powder feeding device. However, the time required from molding to dispensing is 3.3 seconds in the case of using the conventional powder feeding device, whereas that in the case of using the powder feeding device of the present invention is 2 seconds, and the production efficiency is about 1%. It was confirmed that the effect was as high as 0.7 times. In addition, in the powder feeding apparatus of the present invention shown in Table 3, when the powder was supplied without using the distribution supply unit, the time required from molding to dispensing was 3.3 seconds as in the case of using the conventional powder feeding apparatus. Nevertheless, in some cases, the weight variation was large and the minimum weight of the obtained green compact was out of the standard.
