WORKPIECE CLAMPING DEVICE FOR FLEXIBLE WORKPIECE PUNCHING MACHINE

摘要

The present invention relates to a workpiece clamping device for a flexible workpiece punching machine such as a flexible printed circuit board (FPCB), film, etc. and, more specifically, relates to the workpiece clamping device for a flexible workpiece punching machine which prevents inferiority in dimensions by uniformly maintaining flatness even during a change in punching tension in accordance with a blanking space of a material on a punching shaping by uniformly clamping an entire workpiece in a shape of a plane in contact by an upper fixation plate (12) pressuring and operating while rotating towards the upper part of a lower supporting plate (11) and an upper supporting plate (11) rather than partially clamping a side or both sides of a flexible workpiece as before, thus significantly improving a precision of processing.;COPYRIGHT KIPO 2016
