Abstract:
PCT No. PCT/SG94/01246 Sec. 371 Date Jul. 18, 1996 Sec. 102(e) Date Jul. 18, 1996 PCT Filed Dec. 22, 1994 PCT Pub. No. WO95/19856 PCT Pub. Date Jul. 27, 1985A driving device for a bending unit for bending-in an edge flange against a workpiece. The bending unit comprises a stand, supporting the driving device, a supporting surface for the workpiece and a linkage system, which supports a bending tool for the movement along a predetermined path of movement. A motor (14) is mounted on the stand (1) and is coupled to a crankshaft (23) mounted in the stand. The crankshaft supports on a crank pin (25) one end of a connecting rod (26), the other end of which is articulated to a link (8) in the linkage system. The connecting rod (26) is movable, by rotation of the crankshaft (23), between a rest position, in which it keeps the linkage system (8) and the tool in a deactivated position, and a work position, in which it keeps the linkage system (8) and the tool in an end position, where bending-in of the edge flange is completed.
