| 摘要 |
The invention relates to a device for producing a sheet-metal blank (9) by means of laser cutting, comprising a laser cutting device (7) having a back and forth movable laser cutting head (12) extending in a transport direction (T) and in a Y-direction vertically to the transport direction (T), a stretching device (6) for stretching a metal sheet (1) accommodated in the laser cutting device, comprising a first clamping device (16) provided upstream of the laser cutting device (7) for clampingly gripping a first portion of the metal sheet (1), a second clamping device provided upstream of the laser cutting device (7) for clampingly gripping a second portion of the metal sheet (1), and a mechanism (17) for changing a distance between the first (16) and the second clamping device such that a tensile stress is exerted onto a metal sheet (1) that is clampingly gripped therewith. |
