Abstract
A tool system is provided that has a stamp or punch adapter including eccentrically positioned stamp receptacles. This system permits a simple exchange of tool inserts in the stamp adapter. These tool inserts are also usable in another tool system. The system also permits combining the stamp adapter with a stamp shaft, which can also be used in another tool system. These features permit stamping (and punching) with minimal tooling and retooling efforts.
Claims14
A stamp adapter for a tool system comprising:
- a mounting device for accommodating the stamp adapter in a stamp shaft, where a first central axis extends through the mounting device;
- and
- a stamp receptacle having a first opening, the first opening comprising a second central axis extending parallel to and separate from the first central axis, a first through-hole through which the second central axis extends, and a first counterbore,
- wherein the first counterbore is not rotationally symmetrical with respect to the second central axis or the first counterbore comprises at least one recess that is not rotationally symmetrical with respect to the second central axis, and
- wherein the first counterbore comprises (1) a first sector having a circular inner circumferential face with respect to the second central axis, and (2) a second sector, wherein an inner face of the second sector is parallel to a tangent of the through-hole, and a distance between the inner face of the second sector and the second central axis is bigger than a radius of the first through-hole and smaller than a radius of the first sector of the first counterbore.

A stamp adapter comprising:
- a mounting device for accommodating the stamp adapter in a stamp shaft, where a first central axis extends through the mounting device;
- a first stamp receptacle having a first opening and a first through-hole in the first opening, through which a second central axis extends in parallel with and separate from the first central axis;
- a second stamp receptacle having a second opening and a third central axis extending parallel to and separate from the first central axis;
- a second through-hole configured to receive a screw for screwing on a tool insert to the stamp adapter;
- and
- an elevation portion adapted to form an anti-rotation lock with a recess in the stamp shaft, wherein the elevation portion extends from the mounting device.
