Title:

The charge of a tabular metallic material bends and they are molding equipment and a forming process.

Document Type and Number:

Japanese Patent JP6069385

Kind Code:

B2

Abstract:

Provided is a bending apparatus 1 for a plate-shaped metal workpiece 3, including a suction device (suction pad) configured to suck a surface of a plate-shaped metal workpiece 3 in a removable manner; a plurality of expansion and contraction devices 20A-20G (servo screw jacks) each including the suction device mounted on a distal end thereof and being capable of expanding and contracting a length ranging from a proximal end thereof to the suction device and an apparatus base (bed) on which the proximal end of each of the expansion and contraction devices is mounted. The bending apparatus 1 is configured to form the plate-shaped metal workpiece 3 under bending deformation by expanding and contracting the expansion and contraction devices under a state in which the suction device sucks the surface of the plate-shaped metal workpiece 3.
