Title:
成形装置及び成形方法
Document Type and Number:
Japanese Patent JP6490873
Kind Code:
B2
Abstract:
A forming apparatus for forming a workpiece by performing die-closing of a pair of dies includes: a slide on which one of the pair of dies is mounted and which can advance and retreat in an advancing and retreating direction which is a direction toward the other die; a die clamping force generating unit which has a piston movable in the advancing and retreating direction by supplying hydraulic oil thereto and generates a die clamping force; a slide driving unit which advances and retreats the slide in the advancing and retreating direction; and a die clamping force transmitting unit which transmits the die clamping force from the die clamping force generating unit to the slide, in which the slide has a hole portion into which the piston can be inserted, and the die clamping force transmitting unit includes a force transmitting body which is movable between a first position where the force transmitting body covers the hole portion to prevent the piston from entering the hole portion and a second position where the force transmitting body retreats from the first position to allow the piston to enter the hole portion, and transmits the die clamping force from the piston to the slide when the force transmitting body is located at the first position, and a force transmitting body driving unit which moves the force transmitting body.
