MACHINE FOR SPHERICAL MOTION STAMPING Russian patent published in 1997 - IPC

FIELD: metals mechanical shaping. SUBSTANCE: machine for spherical motion stamping has built in tools holders lower tool 25 ad upper tool 24, between which during swinging motion of upper tool 24 by carrier 6 blank form is changing. Upper end of carrier 6 has ball support 8 with dowels, that are located together with lower semisphere of support 8 in flange bush 16. Upper semisphere of support is mounted in the bush by additional bush 11. Flange bush 10 stepped holes have guiding rods with plate springs and cylindrical heads, that are engaged with stop ball bearing 10 mounted in body of flywheel 3. Flange bush 10 is located eccentrically in the flywheel body in roller bearing 13, inner race of which is fixed on flange bush 10 with capability of their joined motion in axial direction in respect to its outer race, that is fixed in body of flywheel 3. Machine, as a version, is used with mechanism of spinning, in which carrier 6 inclination angle is changed due to eccentric positioning of flange bush 10 with movable ball-type support 8 and roller bearing 13 in eccentric bush, that is component of flywheel body and mounted in it main part using bearing means. Gear wheel is mounted in eccentric bush upper part and is engaged with gear shaft of individual drive. EFFECT: improved design. 2 cl, 3 dwg
