ROTARY SHEARING MACHINE WITH OPPOSED BLADES THAT ROTATES AS DESIRED AROUND GEOMETRICAL AXES SUBSTANTIALLY ORTHOGONAL TO THE CUTTING PLANE

摘要

Guillotine shearing machine with two opposing blades (20, 21) fixed to an upper structure (80) and to a lower structure (50), translating in synchrony each parallel to itself and to the opposite blade describing equal circular trajectoires, said blades being fixed to intermediate bodies (24, 47) revolving, in relation to said structures (50, 80), around a geometrical axis substantially orthogonal to the cutting plane and operated by electric ratiomotors (27, 28) to make cuts orientated as desired on the cutting plane and even to produce different polygonal shapes.
