矯正プレス。 A main shaft rotationally driven by a drive source, an upper punch driven vertically via an upper punch drive mechanism in conjunction with the rotational movement of the main shaft, and a main shaft arranged coaxially opposite the upper punch, A lower punch is driven up and down via a lower punch drive mechanism as it rotates, and a straightening die hole is fixedly held on the machine frame and into which opposing ends of the upper and lower punches can be slidably fitted. In the straightening press for powder metallurgy, the lower punch drive mechanism includes a single pressurizing and extruding cam provided on the main shaft, and a follower that comes into contact with the outer cam surface of the cam. As the main shaft rotates, the upper and lower punches are driven in a predetermined phase via the upper and lower punch drive mechanisms to drive the powder compact housed in the die hole from above, from both sides.
A straightening press for powder metallurgy, characterized in that the lower punch simultaneously presses and then the lower punch extrudes.
