A panel bending machine, comprising:
- a counter-blade and a blank holder that are shaped so as to clamp a sheet metal panel to be bent in working positions;
- a C-shaped blade holder that supports at least a first bending blade and a second bending blade at respective terminals of said C-shaped blade holder, said second bending blade having an axis that passes through a free end of said second bending blade;
- and
- an actuating system of said C-shaped blade holder that is structured and arranged so as to swivel said second bending blade in a first working position of said working positions and in a second working position of said working positions;
- wherein said actuating system of said C-shaped blade holder is structured and arranged to operate said C-shaped blade holder such that said second bending blade rotates about the axis that passes through the free end of said second bending blade to move said second bending blade from said first working position to said second working position.
