Abstract (en)
[origin: WO2017085435A1] The invention relates to a forming device for forming a bend in a corrugation. The forming device comprises: a bottom frame (4) having a planar mounting surface (6) for receiving a sheet metal plate having a corrugation projecting in relation to a planar portion of the sheet metal plate, a projecting counter-form (5) placed on the mounting surface and intended to be accommodated in the corrugation, wherein the projecting counter-form has a stationary portion (7) and a movable portion (8) that is hinged, in relation to the stationary portion, around an axis perpendicular to the mounting surface, a top frame (34) placed above the bottom frame, a press configured to lower the top frame towards the bottom frame, and a hollow upper die supported by the top frame between the top frame (34) and the bottom frame (4). The hollow upper die (36, 37) is arranged above the movable portion of the projecting counter-form.
