Abstract
PURPOSE: To obtain a homogeneous sintered alloy of high dimensional accuracy by burying an oscillator in powder fed to the opening face of dies for a sintered alloy and oscillating the oscillator in communication with the molding action of the dies to form a green compact which is uniform in local density as well as overall density.
CONSTITUTION: Punch 12 is raised, the tops of lower punches 13, 14, 15 and the upper surface of floating die 11 are aligned, and leveling valve 4 provided with oscillator 5 is moved so that opening part 12 is covered with valve 4. Oscillating pointers 52 are oscillated while lowering punch 14 to form sleevelike powder (b) with uniform density. Die 11 is then raised, and powder (c) is packed while actuating pointers 52. Powder (c) is successively compacted with punch 12 to form prescribed green compact 2.
