A production installation for producing workpieces from sheet metal by means of forming in a bending operation, in particular by swivel bending or swing bending, comprising: - a bending machine with a fixed machine frame, a lower clamping beam and with an upper clamping beam, wherein at least one of the clamping beams (13, 16) is adjustable relative to the machine frame in order to clampingly hold the workpiece to be manufactured, - a clamping tool with at least one lower clamping jaw and with an upper clamping jaw set from several first upper clamping jaws and at least one second upper clamping jaw, and each of the clamping jaws (5, 6) comprising a base body, wherein the at least one lower clamping jaw is held on the lower clamping beam and the upper clamping jaws (6A, 6B) of the upper clamping jaw set are held on the upper clamping beam, and wherein the at least one second upper clamping jaw in the direction of the longitudinal extension of the clamping beams (13, 16) on a first end section comprises a first clamping jaw part movable relative to its base body from a working position to a pull-out position, wherein the longitudinal extension of the upper clamping jaw set is shorter in the pull-out position than in the working position, and - wherein a bending edge aligned in the direction of the longitudinal extension of the clamping beams (13, 16) is formed by the upper clamping jaw set when the upper clamping jaws (6A, 6B) are in the working position, and a first partial bending edge of the bending edge is respectively formed by each first upper clamping jaw as well as a second partial bending edge is formed by the at least one second upper clamping jaw in the working position, and - a bending unit, said bending unit being adjustable relative to the clamping tool for performing a bending operation, characterized in that - the at least one second upper clamping jaw further comprises a second clamping jaw part movable from the working position in the pull-out position on its second end section arranged at a distance from the first end section in the direction of the longitudinal extension of the clamping beams (13, 16), - at least one first upper clamping jaw is respectively arranged on both sides of the at least one second upper clamping jaw in the direction of the longitudinal extension of the clamping beams (13, 16), and in that - the first upper clamping jaws respectively comprise a first horn at least on their first end regions facing away from the at least one second upper clamping jaw, said first horn being formed to project from the respective base body of the first upper clamping jaw in the direction of the longitudinal extension of the clamping beams (13, 16). - a bending machine with a fixed machine frame, a lower clamping beam and with an upper clamping beam, wherein at least one of the clamping beams (13, 16) is adjustable relative to the machine frame in order to clampingly hold the workpiece to be manufactured, - a clamping tool with at least one lower clamping jaw and with an upper clamping jaw set from several first upper clamping jaws and at least one second upper clamping jaw, and each of the clamping jaws (5, 6) comprising a base body, wherein the at least one lower clamping jaw is held on the lower clamping beam and the upper clamping jaws (6A, 6B) of the upper clamping jaw set are held on the upper clamping beam, and wherein the at least one second upper clamping jaw in the direction of the longitudinal extension of the clamping beams (13, 16) on a first end section comprises a first clamping jaw part movable relative to its base body from a working position to a pull-out position, wherein the longitudinal extension of the upper clamping jaw set is shorter in the pull-out position than in the working position, and - wherein a bending edge aligned in the direction of the longitudinal extension of the clamping beams (13, 16) is formed by the upper clamping jaw set when the upper clamping jaws (6A, 6B) are in the working position, and a first partial bending edge of the bending edge is respectively formed by each first upper clamping jaw as well as a second partial bending edge is formed by the at least one second upper clamping jaw in the working position, and - a bending unit, said bending unit being adjustable relative to the clamping tool for performing a bending operation, characterized in that - the at least one second upper clamping jaw further comprises a second clamping jaw part movable from the working position in the pull-out position on its second end section arranged at a distance from the first end section in the direction of the longitudinal extension of the clamping beams (13, 16), - at least one first upper clamping jaw is respectively arranged on both sides of the at least one second upper clamping jaw in the direction of the longitudinal extension of the clamping beams (13, 16), and in that - the first upper clamping jaws respectively comprise a first horn at least on their first end regions facing away from the at least one second upper clamping jaw, said first horn being formed to project from the respective base body of the first upper clamping jaw in the direction of the longitudinal extension of the clamping beams (13, 16).
