Patent ID: 6955071

Claim:
A mechanical bending apparatus for bending flat workpieces ( 6 ) including at least one beading tool assembly ( 9 , 9 a ) which has at least one tool part that can be moved by means of a selectable bending tool drive ( 27 , 27 a ) to bend the workpiece along a bending line ( 11 ) by being acted on by the movable tool part, said movable tool part comprising a multiplicity of adjacent segments disposed along the direction of the bending line ( 11 ), and each operatively connectable to the bending drive ( 27 , 27 A) to permit ready variation of the number of segments so connected and thereby the operative length of the movable tool part, said bending tool ( 9 , 9 a ) being a swivelable bending tool with a movable tool part in the form of a bending cheek ( 14 , 14 a ) that can swivel on a swivel axis ( 21 ) running in the direction of the bending line ( 11 ), said bending cheek ( 14 , 14 a ) being comprised of a multiplicity of segments ( 17 , 17 a ), at least some of which can be selectively connected to the selectable bending tool drive ( 27 , 27 a ) and can be swiveled on the swivel axis ( 21 ) when the drive connection is selectively made to produce the bending action on the workpiece.
