Powder compacting apparatus

摘要

A powder compacting apparatus ( 1 ) has a top plate ( 3 ), a die plate ( 9 ) and a bottom plate ( 12 ), combined with each other as follows. The top plate ( 3 ) holds upper punches ( 4 ) in place by punch holders ( 5 ), and the die plate ( 9 ) firmly grips a die holder ( 8 ) holding dies ( 7 ). The bottom plate ( 12 ) keeps lower punches ( 11 ) in place gripped by clamps ( 32 ) so that an amount of powder fed into each die ( 7 ) is compacted to give a consolidated powder piece. The die plate ( 9 ) is composed of an upper part ( 9 a) and a lower part ( 9 b) so that the die holder ( 8 ) is sandwiched by and between the parts ( 9 a, 9 b), in such a manner that these parts cooperate with each other to secure each die ( 7 ) in position.
