C-shaped tool holder, setting device with the C-shaped tool holder and method for setting an offset difference of the C-shaped tool holder

A C-shaped tool holder with a frame structure defining a frame plane comprising

• a) a first leg and a second leg that is arranged opposite to the first leg, each leg including a connecting end and an operating end,
• b) a connecting piece by means of which the first leg and the second leg are connected with each other at the respective connecting end, wherein
• c) the operating end of the first leg serves for fastening a punch with an associated drive unit defining a movement direction of the punch in the direction of the operating end of the second leg, and the operating end of the second leg serves for fastening a die dome wherein
• d) an offset difference due to a gravity-caused offset between the operating end of the first and the operating end of the second leg perpendicular to the frame plane can be minimized by at least one compensating element which is arranged at one or more of the following elements:
• the first leg, the second leg or the connecting piece, and
• e) an intersecting point of a first straight line corresponding to the movement direction of the punch in the direction of the operating end of the second leg, and a second straight line extending from the operating end of the second leg in the direction of the operating end of the first leg, is settable to an operating point by means of the at least one compensating element.
