Abstract
PURPOSE:To improve the plastic fluidity of a working article and to perform plastic working with high accuracy by approximately moving two dies to each other and continuously changing the rocking amplitude of the die on which the article is mounted while the dies rock. CONSTITUTION:A plate-like article 10 is mounted on a lower die 11 of a plastic working equipment. At this time, a slider 15 is located at the lowermost descending point in a bore and the upper die 12 is located at the uppermost ascending point. Under this state, a rotating shaft 23 is rotated to operate a lever crank mechanism 17 and a toggle link mechanism 16 constituting a lower die moving device. In this manner, the lower die 11 rises at a required speed from the lowermost descending position in the bore 14 and approaches toward the upper die 12. At the same time, a main motor 37 of a variable amplitude device 29 is rotated, a toggle link mechanism 56 composed of a rocking lever 28 and a connecting rod 58 is operated to lower the upper die 12 synchronously toward the lower die 11. In addition, a rocking device 30A of the rocking lever 28 and a connecting lever 30 is driven by the rotation of the main motor 37. Therefore, the upper die 12 rocks at an initial set rocking angle during its descending movement.
