Abstract

PURPOSE:To facilitate the plastic working of high accuracy by rocking at least one part of both dies during approaching and receding movement and varying the vibration amplitude while under rocking. CONSTITUTION:When a start button is pushed, the lower die interlocking mechanism consisting of a toggle rink mechanism 16 and lever crank mechanism 17 is actuated at the necessary timing to start the rocking of an upper die 12. A command is sent to an amplitude adjusting mechanism 29 from the control device of a program control means at the timing when the rocking amplitude in rocking reaches the lower dead center and the rocking amplitude thereof is gradually attenuated with a 1st mode. The pressure by both dies 11, 12, the rocking of the upper die 12 and the attenuation of the rocking amplitude are thus given to a body 10 to be worked and the plastic working of high accuracy can be executed.
