Abstract (en)
[origin: EP3357597A1] Apparatus (20,30)for bending a metal blank (50) into a predetermined shape, said apparatus comprising a land (32) having a substantially planar surface (33) on which the blank to be bent is placed, where an aperture (34) is provided in said land (32), said aperture having (34) a size and shape allowing a bending piston (1) to move perpendicular and through said planar surface (33), said bending piston (1) being operated by a pressure plate (31), such that the pressure plate (31) can exert a pressure on the bending piston (1) thereby urging the piston (1) through the aperture (34), where the bending piston (1) engages the blank (50) to be bent, such that the blank (50) is deformed/bent along a first surface (37) on a counter land (35) positioned on the other side of the blank (50), the bending piston (1) having a longitudinal body (2) with a cylindrical cross-section, where in a first end of the body (2) a pressure plate engagement surface (9) is provided and in an opposite second end a blank forming section (4) is provided, where said blank forming section (4) is coupled to the body (2) by a tilting section (3).
