Tool head for a tool
A tool head is provided for a hydraulically actuatable tool. The tool head has an essentially C-shaped head body with two C-legs, and a connecting web connecting the C-legs. Each C-leg has a tool carrier for receiving a tool part. The second tool carrier is mounted to be displaceable to the first tool carrier from a first starting position remote from the first tool carrier while traversing a device jaw of the C-shaped head body into a final working position adjacent to the first tool carrier. The connecting web has several through openings lying one behind the other along the longitudinal axis and are separated by a material bracing. The through openings follow an arched shape of the connecting web, and not a line parallel to the longitudinal axis of the tool head.

the connecting web being offset from the longitudinal axis, the connecting web having multiple through openings extending between the opposite sides and lying one behind the other and which are separated by material bracing; and
wherein the through openings follow an arched shape of the connecting web and wherein an imaginary line is defined which extends parallel to the longitudinal axis, extends through one of the through openings and extends through the device jaw.
10 . The tool head according to claim 9 , wherein an edge area of the connecting web spaced apart from the device jaw by the through openings has an edge height transverse to the longitudinal axis that measures 20 percent to 40 percent of an opening height of each of the through openings.
11 . The tool head according to claim 9 , wherein the connecting web has three to five through openings which, as viewed from the side transverse to the longitudinal axis of the tool head, are arranged arched one next to the other from the first leg up to the second leg.
12 . The tool head according to claim 9 , wherein the through openings expand proceeding from the device jaw up to an edge area of the connecting web facing away from the device jaw.
13 . The tool head according to claim 9 , wherein the material bracing has a bracing width as viewed transverse to an opening plane of each through opening that corresponds to 10 percent to 50 percent of an opening width of each through opening.
14 . The tool head according to claim 9 , wherein the material bracing has an essentially constant bracing width proceeding from the device jaw up to an edge area of the connecting web facing away from the device jaw.
15 . The tool head according to claim 9 , wherein the material bracing is waist-shaped as viewed transverse to an opening plane of each through opening, wherein the material bracing initially tapers proceeding from the device jaw up to an edge area of the connecting web facing away from the device jaw, and then expands again.
