The construction principle and the pressure sheet process of a single press machine

　　The press press press process is carried out automatically continuously by adding and pressurizing to the piece The construction of the press is to complete such a process, Figure 16-6 for the electric single-punch press, Figure 16-7 for the main play part of the press
As shown in Figure 16-7, when the wheel is turned by hand at the beginning, the following actions are generated; (1) up-punch 1-up, down-down fall; (2) the feed boot is transferred to the die ring 2, the boots are filled with mold holes; (3) the feed boot transfer away from the mold, At the same time up-down down, the particles into tablets; (4) up and down the tablet from the mold hole to the top, to the underside of the tablet and the die ring above level; (5) feed boots transferred to the die ring above the tablet pushed down the die table into the receiver, At the same time the downfall and fall The mold hole is also filled with particles; The weight and hardness of the tablet (i.e the size under pressure) can be adjusted by regulator 5 The lower the downfall, the greater the increase in the mold hole capacity, which can be borrowed to increase the weight of the tablet; However, in any case must use the chip regulator 4, so that the downstroke rose to the zui high, the co-top must be flush with the mold trap table The lower the upper flush drop, the greater the pressure, so the harder the tablet, the higher the drop, the smaller the pressure, the looser the tablet
Although the various pressure film ingress s (a) is different, the principle of action is basically similar.
