The invention relates to a magnetic field press, in particular to a one-die multi-piece magnetic field press, and particularly relates to a one-die multi-piece magnetic field press and a feeding method thereof.
Background
Because of low automatic and accurate weighing efficiency of magnetic powder, the existing one-die multi-piece magnetic field press generally adopts constant volume feeding, namely, the total weight of a plurality of magnetic powder pieces (such as six pieces, 100 g for each piece and 600 g for the total weight) is weighed, and then all the magnetic powder pieces (600 g) are filled (namely, constant volume) into all mold cavities through a feeding mechanism. Because the fluidity of the magnetic powder is poor, although each die cavity is filled (fixed volume), the weight error of the magnetic powder in each die cavity is larger, the magnetic powder is particularly prominent to tile-shaped parts, square bars, cylindrical parts and the like with smaller section sizes, and the deviation of the overall dimensions of each molded part is caused, so that the magnetic powder is wasted, and the cost is increased.

Therefore, when the magnetic powder weighing machine is used for weighing each time, the main feeding hole firstly feeds most (more than 90 percent, such as 95 percent) of the needed magnetic powder into the weighing machine at one time, and then the electromagnetic vibration feeder is used for supplementing the allowance, so that the efficiency of each weighing is greatly improved compared with that of a single electromagnetic vibration feeder.
