METAL PROCESSING APPARATUS AND METHOD FOR MANUFACTURING METAL

PROBLEM TO BE SOLVED: To enhance a product quality in such a manner that abnormality of condition of contact between a component which supports a metal and the metal is detected with a higher accuracy during bending processing of the metal.SOLUTION: A metal processing apparatus comprises: a delivery system which delivers a long metal in a longer direction; a support mechanism which guides and supports the delivered metal at one portion in the longer direction; and a holding mechanism which holds the metal at another portion of said metal, and adds a flexure load to the metal. The support mechanism is provided with a measurement mechanism which measures a friction force between itself and the support mechanism when the metal is delivered, and a processing reaction force which acts on the support mechanism when the flexure load is added onto the metal.SELECTED DRAWING: Figure 3 【課題】金属材に対する曲げ加工において、当該金属材を支持する部材と当該金属材との接触状態の異常を加工中により精度良く検出することにより、製品品質を向上させることを可能にする。【解決手段】長尺な金属材を長手方向に送り出す送出機構と、送り出された前記金属材を長手方向の一部位において案内支持する支持機構と、前記金属材の他の部位において当該金属材を挟持するとともに前記金属材に曲げ荷重を負荷する挟持機構と、を備え、前記支持機構には、前記金属材が送り出される際の前記支持機構との間の摩擦力、及び前記金属材に前記曲げ荷重が付加される際に前記支持機構に作用する加工反力を測定する測定機構が設けられる、金属加工装置を提供する。【選択図】図３
