METHOD AND DEVICE FOR CUTTING HIGH-TENSILE SHEET METAL, AND PRESS

摘要

The invention relates to a method and device for bending cutting a high-tensile workpiece, particularly a sheet metal made of martensitic steel. The device comprises a supporting surface (16), which is provided for supporting the workpiece (3) and which has an edge matched to the desired cut contour. The device also comprises a cutting blade (11), which has a cutting edge (12) matched to the cut contour, and comprises a pre-bending device (19), which is placed with a lateral distance from the cut contour and is provided for subjecting the workpiece to the action of a bending moment and thus a tensile stress in the area of the cut contour before the cutting blade (11) penetrates the workpiece.
