FIELD: technological processes.
SUBSTANCE: invention relates to device and method of making cutting plates workpieces from sintered powder. Cutting plate workpiece (10) making device (40) from pressing sintered powder, having central axis (A) determining axial and radial directions, comprises base (42), having through hole (50), plurality of radial channels (52) for male dies and plurality of radially directed matrix channels (54), cover (44), made with possibility to be fitted on base (42) and having through hole (46), wherein central axis (A) passes through base and cover through holes (50, 46) during cover (44) installation on base (42), upper male die (56) and opposite lower male die (58), wherein, upper male die (56) is made with possibility of axial movement through cover through hole (46), and lower male die (58) is made with possibility of axial movement through base through hole (50), plurality of side male dies (60) arranged in opposite pairs, wherein side male dies are made with possibility of radial movement in channels (52) for male dies, and plurality of matrix rods (74), made with possibility of radial movement in matrix channels (54), wherein each matrix rod (74) is common for two adjacent side male dies (60) and is located between them, wherein each matrix rod (74) has front moulding surface (78) and two guide surfaces (82), wherein two adjacent side male dies (60) are made with possibility of sliding along common rod (74) matrix guide surfaces (82). Side male dies slide on matrix rods, wherein side male dies and matrix rods move in base channels, on which cover is installed, upper and lower male dies are moving in cover and base through holes, and female die rods are fixed during sintered powder pressing, wherein upper, lower and side male dies form workpiece surfaces, and matrix rods form workpiece edges.
EFFECT: invention is aimed at higher quality of workpieces.
