Guillotine shears for sheet metal

A guillotine shears for sheet metal with two knife carriers movable relative to one another along a working stroke, comprising:

• a frame structure comprising at least one side piece;
• a lower knife carrier rigidly connected to the at least one side piece and aligned in a longitudinal direction;
• and
• an upper knife carrier movably supported for performing the working stroke and co-aligned in the longitudinal direction of the lower knife carrier;
• wherein the knife carriers are connected with one another by way of at least three leaf spring arrangements;
• wherein at least two leaf spring arrangements are aligned parallel to one another in a common plane, and at least one leaf spring arrangement is aligned perpendicular to the at least two leaf spring arrangements in a plane that is parallel to the common plane;
• wherein the at least two leaf spring arrangements extend perpendicular to the longitudinal direction of the knife carriers, and the at least one leaf spring arrangement extends in the longitudinal direction of the knife carriers;
• wherein each of the at least three leaf spring arrangements is connected at one end to the lower knife carrier and connected at the other end to the upper knife carrier;
• and
• wherein the elastic deformation region of the at least three leaf spring arrangements determines the maximum range of the relative movement of the knife carriers.
