Document Type and Number:
Japanese Patent JP6327903
Kind Code:
B2
Abstract:
There is provided an apparatus for manufacturing a thin uneven member. The apparatus includes a lower die fixed to a press bed, an upper die fixed to a ram and disposed opposed to the lower die, and a pressure-drive unit which presses the ram using a servo motor as a power source, the servo motor being fixed to a first support member. The pressure-drive unit includes a motion converting mechanism which converts a rotation of the servo motor to a linear motion of a lifting member, and a cylinder block connected and fixed to the first support member and including first and second pistons arranged in series vertically, wherein the first piston is connected to the lifting member through a second support member, and the second piston, larger in diameter than the first piston, presses the ram.
