Abstract (en)
[origin: EP2422968A2] A slide drive device implements a high-precision press operation due to a small amount of backlash. The slide drive device is configured so that a slide (90)-side female spherical surface (48) and a connecting rod (20)-side male spherical surface (38) come in contact with each other during press forming so that a press-forming load (Pprs) is transmitted to the connecting rod through the female spherical surface (48) and the male spherical surface (38), and an upper side (52) of a holding member (51) is suspended on a circular member (41) during a period other than a press-forming period so that the female spherical surface (48) and the male spherical surface (38) are separated from each other, and a slide load (Psrd) is transmitted to the connecting rod (20) through the circular member (41) and a horizontal pin member (45).
