The present invention relates to a workbench, and respective operating and manufacturing methods, for the cold intervention, folding, bending or deformation of metal plates or sheets, the constructive and functional features of which provide a solution to achieve an optimal balance between power and flexibility, such that it allows performing custom works on metal plates or sheets under power conditions that exceed human capacity. In that sense, the workbench provides a work area with multiple actuation and power options, constituting a plethora of possible combinations for the intervention, folding, bending, twisting or deformation of metal sheets of different shapes. 11. A workbench () for the cold intervention , folding , bending , twisting or deformation of metal sheets , characterized in that it comprises:{'b': 2', '3', '21, 'a benchtop () with a plurality of channels () for receiving a metal sheet ();'}{'b': 22', '21', '23', '21, 'a cord () for acting on the metal sheet () through a power point () fixed in said metal sheet ();'}{'b': 12', '22', '22', '12', '13', '22', '22', '12, 'tension adjustment means () for pulling or releasing the cord (), where one of the ends of the cord () is coupled to said tension adjustment means (); force transmission means () through which the cord () passes to obtain a mechanical advantage, according to the tension applied on the cord () by the tension adjustment means ();'}{'b': 12', '13', '2, 'wherein the tension adjustment means () and the force transmission means () are arranged on the benchtop (); and'}{'b': 3', '2', '21', '13', '23', '21', '12', '2, 'wherein the channel of the plurality of channels () of the benchtop () for receiving the metal sheet (), the force transmission means () and the position of the power point () fixed in the metal sheet () and of the tension adjustment means () on the benchtop () are selected according to an angle of actuation and/or a desired mechanical advantage.'}21238910. The workbench () for ...
