Title
(EN) CROWNING METHOD FOR PRESS BRAKE, AND PRESS BRAKE
(FR) PROCÉDÉ DE BOMBEMENT POUR PRESSE PLIEUSE, ET PRESSE PLIEUSE
(JA) プレスブレーキにおけるクラウニング方法及びプレスブレーキ
Abstract
(EN) Provided is a crowning method for a press brake that comprises: an upper table and a lower table, which vertically face each other; and first slits formed in both the left and right sides of the upper table or the lower table and open in the left-right direction. The crowning method comprises performing a crowning adjustment by upwardly or downwardly deforming end sides of the lower portions or the upper portions of the first slits in the upper table or the lower table.
(FR) L'invention concerne un procédé de bombement pour une presse plieuse qui comprend : une table supérieure et une table inférieure, qui se font face verticalement ; et des premières fentes formées à la fois sur les côtés gauche et droit de la table supérieure ou de la table inférieure et ouvertes dans la direction gauche-droite. Le procédé de bombement consiste à réaliser un ajustement de bombement par déformation vers le haut ou vers le bas de côtés d'extrémité des portions inférieures ou des portions supérieures des premières fentes dans la table supérieure ou la table inférieure.
(JA) 上部テーブルと下部テーブルとを上下に対向して備え、前記上部テーブル又は前記下部テーブルの左右両側に、左右方向に開口した第1のスリットを備えたプレスブレーキにおけるクラウニング方法は、前記上部テーブル又は前記下部テーブルにおける前記第1のスリットの下側部分又は上側部分の端部側を、上方向又は下方向に変形させてクラウニング調整を行う、ことよりなる。
