Abstract
A device for shaping a metal sheet by die stamping, the device including first and second trunnions configured to be fastened respectively to two opposite ends of a sheet, the sheet being configured to be shaped by die stamping, wherein the first and second trunnions define respective first and second bearing surfaces configured respectively to guide turning of the trunnions, the first bearing surface defining a peripheral groove around a pivot axis of the first trunnion while the second bearing surface is smooth along a pivot axis of the second trunnion.

A device for shaping a metal sheet by die stamping, the device comprising:
- first and second trunnions configured to be fastened respectively to two opposite ends of a sheet, the sheet adapted to be shaped by die stamping,
- wherein the first trunnion defines a first bearing surface and the second trunnion defines a second bearing surface, the first and second bearing surfaces configured respectively to guide turning of the trunnions, and
- wherein the first bearing surface defining a peripheral groove around a pivot axis of the first trunnion while the second bearing surface is smooth along a pivot axis of the second trunnion, thereby allowing the second trunnion to move in translation along the pivot axis of the second trunnion and preventing the first trunnion from moving in translation along the pivot axis of the first trunnion.
