Abstract (en)
[origin: EP0924005A2] The flanging operation is a folding operation of the contour flanging (20) of an exterior sheet or panel (21), on the edge of another inside one (22) by plastic mechanical deformation to connect both sheets. This folding is carried out in two successive operations: a pre-flanging step that folds said flange (20) to a intermediate position, and another final flanging position in which said flange (20) is closed totally over the edge of the interior one (22). The rising and lowering of the flanging group (2) is obtained by electric operation that causes the rotation of a spindle (7) in which the ball nut (4) is mounted. The spindle (7) includes an elastic package (10) that absorbs the force exerted by the flanging unit (2). The winding of the electric motor (1) ceases operating upon reaching a certain current level depending on the force to be exerted. The final flanging blades (14) are located in the top part of the flanging group and are attached to the same blade holder (13) as the pre-flanging blades (15). <IMAGE>
