Abstract

Dispositivo per misurare l'angolo di un pezzo, in particolare per rilevare l'angolo di piegatura di un pezzo di lamiera (2) durante un'operazione di piegatura del pezzo su una pressa piegatrice avente un punzone (4) ed una matrice (6) mutuamente cooperanti. Il dispositivo comprende una coppia di organi tastatori (12) che sono totalmente svincolati cinematicamente fra loro. Ciascun organo tastatore è associato a mezzi di spinta che tendono a portare le superfici attive (16) degli organi tastatori (12) a contatto con rispettive porzioni (2a, 2b) del pezzo (2) in corso di piegatura. I mezzi di spinta (18) associati ad un organo tastatore (12) sono totalmente indipendenti dai mezzi di spinta associati all'altro tastatore e sono atti a consentire un movimento di traslazione del rispettivo organo tastatore (12) in modo totalmente indipendente dal movimento dell'altro tastatore (12). (Fig.5)
