Abstract
【解決手段】パンチ金型1とダイ金型25との協働により板状のワークWの打抜き加工を行う際のカス上り防止方法であって、前記パンチ金型1に備えた板押え7によってワークを前記ダイ金型25の上面に押圧し、前記パンチ金型1に備えたパンチ刃部13によって前記ワークの一部をダイ金型25におけるダイ孔27内に打抜き、前記パンチ刃部13の上昇時であって前記パンチ刃部13が前記ワークの下面より上側で前記ワークの上面より下側に位置するとき、前記ワークに既に加工された穴の部分から前記パンチ刃部13の下側へ指向して大量の流体を吹き込み、前記パンチ刃部13の下側に位置する小片のカスを前記ダイ孔27内に落下するものである。
