Abstract

PURPOSE:To easily realize the plastic working of high accuracy by approaching and separating a pair of dies, vibrating one part of the dies in the same direction as the approaching movement or in the direction inclined at an optional angle to the direction thereof and varying the vibration amplitude during the vibration. CONSTITUTION:When the main motor 37 of a variable stroke device 29 is rotated, the lift operation synchronizing with the lift operation of a lower die 11 is given to an upper die 12. When the eccentric motor 45 of the variable stroke device 29 is rotated, the stroke amt. can be varied during the reciprocating movement thereof. The vibration movement of the necessary angle is given on the vibrating body with its horizontal shaft center as the center by rotating a servomotor in either positive or reverse direction. A precise plastic working can be thus executed.
