To provide a technique capable of performing bending formation with high accuracy in a bending formation device.SOLUTION: A bending formation device comprises: a main forming part which performs bending formation of a component; an inspection information acquisition part which inspects the component formed by the main forming part, and acquires inspection information concerning the formed component; an angle estimation part which estimates a bent angle of the formed component; a correction amount calculation part which calculates a correction amount of bending formation by use of a differential value between a target value of a component bent angle and an estimation value of the bent angle of the formed component; and a correction forming part which performs correction forming of the formed component by use of the calculated bending formation correction amount.SELECTED DRAWING: Figure 1 【課題】 曲げ成形装置において、高精度に曲げ成形が可能な技術を提供する。【解決手段】 曲げ成形装置は、部材に曲げ成形を行う主成形部と、主成形部によって成形された成形部材を検査して、成形部材の検査情報を取得する検査情報取得部と、検査情報を用いて、成形部材の曲げ角度を推定する角度推定部と、部材の曲げ角度の目標値と、成形部材の曲げ角度の推定値との差分値を用いて、曲げ成形の修正量を演算する修正量演算部と、演算された曲げ成形の修正量を用いて、成形部材に修正成形を行う修正成形部と、を備える。【選択図】 図１
