摘要： In a powder feed apparatus and a control method thereof, a powder molding press feeds powder from a hopper of the powder feed apparatus to a feeder slidably disposed on a die plate of the press proper. Powder is charged into a die in the die plate. The feeder is electronically controlled to a correct position on the die. Powder is fed from a powder feed apparatus into a feeder slidably disposed on a die plate of a press proper and a feeder drive motor is servo-controlled by an output obtained by comparing detection outputs from a position detector for detecting the vertical position of the die plate of the press proper and a position detector for detecting the position of the feeder in its sliding direction. As a result, it is possible to avoid the trouble of changing cams or inserting insert cams every time the shape of the compact being molded changes. It is also possible to easily make changes to the movement speed of the feeder in correspondence with changes to the compact.

摘要： A pair of non-circular gears having a fixed sum of the radius of the gears is used as transmission gears secured between a power shaft and a crank shaft. Each radius of the non-circular gears increases or decreases according to the required rotation. A powder feeding time in one cycle is prolonged by delaying the lowering velocity of an upper ram near the lowermost dead point of the upper ram which carries out the powder compacting and performing a quick return motion of the upper ram after a compacting zone.
