Abstract

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.

First claim

The invention claimed is:

1 . A tool head for a hydraulically actuatable tool comprising:
a metal generally C-shaped head body having a front end, a rear end and first and second opposite sides, the C-shaped head body defining a longitudinal axis, the C-shaped head body having first and second legs and a connecting web connecting the legs which form a device jaw; the first and second legs lying opposite each other along the longitudinal axis, the first leg having a first tool carrier which is configured to receive a first tool part, and the second leg having a second tool carrier which is configured to receive a second tool part, wherein the second tool carrier is displaceable relative to the first tool carrier along the longitudinal axis, wherein the second tool carrier can be displaced from a first starting position remote from the first tool carrier and into a final working position adjacent to the first tool carrier; and 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 are separated by material bracing, and wherein the through openings follow an arched shape of the connecting web, such that a first imaginary line is defined which passes through each through opening, and wherein a second imaginary line which is parallel to the longitudinal axis and passes through each through opening cannot be defined.

2 . The tool head according to claim 1 , 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.

3 . The tool head according to claim 1 , 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.

4 . The tool head according to claim 1 , 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.

5 . The tool head according to claim 1 , 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.

6 . The tool head according to claim 1 , 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.

7 . The tool head according to claim 1 , 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.

8 . The tool head according to claim 1 , wherein each through opening has an opening width relative to a direction parallel to the longitudinal axis of the tool head corresponding to 50 percent to 100 percent of a width of the device jaw.

9 . A tool head for a hydraulically actuatable tool according to claim 1 , further comprising:
a metal generally C-shaped head body having a front end, a rear end and first and second opposite sides, the C-shaped head body defining a longitudinal axis, the C-shaped head body having first and second legs and a connecting web connecting the legs which form a device jaw; the first and second legs lying opposite each other along the longitudinal axis, the first leg having a first tool carrier which is configured to receive a first tool part, and the second leg having a second tool carrier which is configured to receive a second tool part, wherein the second tool carrier is displaceable relative to the first tool carrier along the longitudinal axis, wherein the second tool carrier can be displaced from a first starting position remote from the first tool carrier and into a final working position adjacent to the first tool carrier; 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.

16 . The tool head according to claim 9 , wherein each through opening has an opening width relative to a direction parallel to the longitudinal axis of the tool head corresponding to 50 percent to 100 percent of a width of the device jaw.

17 . A tool head for a hydraulically actuatable tool comprising:
a metal generally C-shaped head body having a front end, a rear end and first and second opposite sides, the C-shaped head body defining a longitudinal axis, the C-shaped head body having first and second legs and a connecting web connecting the legs which form a device jaw; the first and second legs lying opposite each other along the longitudinal axis, the first leg having a first tool carrier which is configured to receive a first tool part, and the second leg having a second tool carrier which is configured to receive a second tool part, wherein the second tool carrier displaceable relative to the first tool carrier along the longitudinal axis, wherein the second tool carrier can be displaced from a first starting position remote from the first tool carrier and into a final working position adjacent to the first tool carrier; and the connecting web having multiple through openings extending between the opposite sides and lying one behind the other and are separated by material bracing, and wherein one of the through openings is positioned above the other through openings in a direction
