Abstract

Metal-sheet-following device for a bending press, including a pivoting support (6) actuated by one or more articulated systems, each of them being constituted by at least two levers (9),(10) and two links (15),(17) forming, together with the support, at least two parallelograms which can be deformed in the manner of a pantograph. The fixed articulation points (7),(8) of the two levers on the one hand, and the articulation points (16),(18) of the links on the support on the other hand, are aligned with the point which is coincident with the axis of rotation of the metal sheet about the die edge. Rotational actuation of the assembly follows the movement of the moving table of the press by means of a control mechanism of the "master-slave" type which has the effect of minimising the following error in the metal sheet which is being bent. The metal sheet (5) is rendered integral with the support (6) but the latter may slide slightly in relation to its articulation points so as to follow the sliding of the metal sheet during the bending. The support may either be a plate or a set of arms, the spacing of which may be adjusted. The arms may be integral or independent.
