Abstract: The invention concerns a forming device intended to form a bend in a corrugation, the forming device comprising: a bottom frame (4) having a planar mounting surface (6) intended to receive a sheet metal plate having a corrugation projecting relative to a planar portion of the sheet metal plate, a projecting counter-form (5) arranged on the mounting surface and intended to be accommodated in the corrugation, the projecting counter-form having a stationary portion (7) and a movable portion (8) that is hinged, relative to the stationary portion, about an axis perpendicular to the mounting surface, a top frame (34) arranged above the bottom frame, a press configured to lower the top frame towards the bottom frame, and a hollow upper die carried by the top frame between the top frame (34) and the bottom frame (4), the hollow upper die (36, 37) being arranged above the movable portion of the projecting counter-form.

Abstract: The invention relates to a bending device for forming corrugations in a metal sheet including: a lower frame; an upper frame able to move vertically between a rest position and a bending position; at least two dies, carried by the lower frame; one being fixed with respect to the lower frame and the other mounted with the ability to slide; at least two punches carried by the upper frame; one being fixed and the other being mounted with the ability to slide on the upper frame; the bending device being designed so that, in operation, as the upper frame moves towards its bending position, the metal sheet transmits a pulling force to the sliding punch and to the sliding die which force moves them from a spaced-apart position toward a close-together position.

Abstract: A bending device for forming a corrugation in a metal sheet, the bending device having a frame, a die having two die elements, each having a concave half-impression, mounted able to slide on the frame; a punch having a head able to engage inside the impression of the die so as to press the metal sheet; and two side clamps mounted sliding and able to move vertically with respect to the lower frame so as to clamp the metal sheet against the bearing surfaces of the die elements. During the displacement of the punch into its bending position, the metal sheet transmits a traction force to the die elements and to the side clamps so as to displace them into their near position.
