Flanging device for pre-flanging and flanging of components

A hemming device for the prehemming and finishing hemming of components with a first component having an upright standing flange before hemming and a second component with a flat edge area, the device comprising:

• a base;
• a folding bed performing the hemming stroke with respect to said base, said folding bed having support surfaces for the components arranged to be approached at least in an edge area;
• at least one prefolding jaw movable into a prehemming position, with a flange contact surface arranged obliquely to said flange;
• at least one finishing folding jaw having contact surfaces arranged in parallel to said edge area;
• a finishing folding jaw slide moving said finishing folding jaw from an outside to an inside into a finishing hemming position;
• a pivoting plate, said prefolding jaw being fastened to said pivoting plate for pivoting from the outside to the inside into the prehemming position and lockable in the prehemming position.

A hemming device for hemming a workpiece, the device comprising:

• a base;
• a folding bed supportable of the workpiece and movable with respect to said base in a hemming path between a hemming position and a retracted position;
• a prefolding jaw movable with respect to said base into and out of said hemming path, said folding bed being movable toward said prefolding jaw arranged in said hemming path to pre-fold a flange of the workpiece;
• a finishing jaw movable with respect to said base into and out of said hemming path, said folding bed being movable toward said finishing jaw arranged in said hemming path to finish fold the flange of the workpiece, said prefolding jaw and said finishing jaw being movable in separate directions angularly spaced from said hemming path.
