A tool storage system) for a production plant, in particular for free-form bending of workpieces made from a sheet metal, by means of a bending press, comprising - at least one tool storage for holding at least one bending tool, wherein the bending tool has at least one bending punch and at least one bending die, - wherein the tool storage comprises at least one upper storage rail and at least one lower storage rail, which at least one upper storage rail and at least one lower storage rail are disposed spaced apart from one another at a vertical distance, as well as locally fixed in place relative to one another, wherein the at least one upper storage rail defines an upper storage plane, and the at least one lower storage rail defines a lower storage plane, - at least one tool manipulation unit, - wherein the tool manipulation unit comprises at least one upper tool manipulation device and at least one lower tool manipulation device, - at least one provisioning unit having at least one upper and/or lower provisioning rail (56, 57), characterized in that - the at least one upper tool manipulation device is disposed in the region of an end face of the at least one upper storage rail and the at least one lower tool manipulation device is disposed in the region of an end face of the at least one lower storage rail, - the at least one upper tool manipulation device has at least one upper working rail and at least one upper auxiliary rail disposed laterally relative to the former and running parallel with regard to the upper working rail, and furthermore comprises at least one upper drawing-in device for at least one bending punch to be held as well as at least one upper pushing-out device for at least one bending punch to be discharged, - the at least one lower tool manipulation device has at least one lower working rail and at least one lower auxiliary rail disposed laterally relative to the former and running parallel with regard to the lower working rail, and furthermore comprises at least one lower drawing-in device (44 for at least one bending die to be held, as well as at least one lower pushing-out device for at least one bending die to be discharged, - the at least one upper tool manipulation device can be displaced parallel with regard to the upper storage plane, as well as in the vertical direction with regard to the longitudinal expanse of the at least one upper storage rail, along an upper longitudinal guide arrangement, - the at least one lower tool manipulation device can be displaced parallel with regard to the lower storage plane, as well as in the vertical direction with regard to the longitudinal expanse of the at least one lower storage rail, along a lower longitudinal guide arrangement. -
