Abstract
A press tool for joining workpieces by forming, has at least two pressing jaws that can be moved relative to one another, with which pressing jaws the workpieces to be joined can be encompassed, at least partially, and which form a matrix for at least one of the workpieces to be joined, and has a closing point formed by mutually dedicated end faces of two of the pressing jaws. In an area adjacent to at least one of the end faces of the closing point, the surface of the associated pressing jaw may be retracted by an offset.
Claims18
A press tool for joining workpieces by forming, the press tool comprising:
- a first pressing jaw and a second pressing jaw, which are movable relative to one another, with which jaws the workpieces to be joined can be encompassed, at least in part;
- and
- a closing point,
- wherein the first and second pressing jaws form a mold for at least one of the workpieces to be joined,
- wherein the closing point is formed by end faces of two of the pressing jaws which are assigned to one another,
- wherein a target contour is formed by a space enclosed by the pressing jaws when the press tool is closed,
- wherein, in a region which adjoins at least one of the end faces of the closing point, an associated pressing jaw includes a recessed surface, recessed from the target contour by an offset, and
- wherein the recessed surface has a constant spacing from the target contour.
A press tool for joining workpieces by forming, the press tool comprising:
- a first pressing jaw and a second pressing jaw, which are movable relative to one another, with which jaws the workpieces to be joined can be encompassed, at least in part;
- a closing point;
- and
- a receiving portion,
- wherein the jaws form a mold for at least one of the workpieces to be joined,
- wherein the closing point is formed by end faces of two of the pressing jaws which are assigned to one another,
- wherein a target contour is formed by a space enclosed by the pressing jaws when the press tool is closed,
- wherein, in a region which adjoins at least one of the end faces of the closing point, an associated pressing jaw includes a recessed surface, recessed from the target contour by an offset,
- wherein the recessed surface has a constant spacing from the target contour, and
- wherein, due to the recessed surface, the receiving portion for deformation material of at least one of the workpieces is also formed when the press tool is closed.
