Description
上型と、
該上型との間にワークを介在させた状態で前記上型に対して相対的に接近する方向に移動することによって前記ワークを剪断により裁断する裁断刃を備えた下型と、
該下型の前記上型に対する相対的な移動により前記上型との間に前記ワークを挟んで保持するワーク押えと、を備え、
前記下型は、前記裁断刃から前記上型及び下型の相対的な移動方向に沿って延在する第1外側面を有し、
前記ワーク押えは、前記ワークを押えるワーク押え面と、該ワーク押え面の前記裁断刃に対向する側の端部から前記上型及び下型の相対的な移動方向に沿って延在して前記下型の第1外側面に対向する内側面と、前記ワーク押え面の前記裁断刃から離間する側の端部から前記上型及び下型の相対的な移動方向に沿って延在する第2外側面とを有しており、前記下型の第1外側面と前記ワーク押えの第2外側面との間のワーク押え距離がワークの厚みの5倍以上12倍以下となるように配置されていることを特徴とする。
以下、実施例に係るワークWKを作製し、実施形態に係るMEGA10の裁断装置40によりワークWKを裁断して、距離L(mm)が、厚みt(mm)の5倍以上12倍以下の範囲内にあれば、裁断精度を確保することができるか否かについて検証を行った。
