Abstract
A method and an apparatus are provided for marking a sheet-shaped workpiece using a marking tool. The marking tool is mounted in a punch holder of a punch press and a counter-support is fixed in place on a side opposite of a marking surface of the workpiece to be marked. The surface of the workpiece is marked by displacing the workpiece in its plane while engaging the marking tool with the workpiece. In one form, a support roller provides counter-support. In another form, an elastic element is cooperatively associated with the punch stroke of the punch press to translate an exactly defined contact pressure force between the tool tip and the workpiece to be marked.
Claims29
An apparatus for marking a sheet-shaped workpiece, said apparatus comprising:
- a punch press, said punch press having a stroke driving mechanism;
- at least one marking tool disposed in the punch press, said marking tool comprising a tool tip, a guide bush axially supporting a support, a marking tool elastic element, and a drive head, said marking tool elastic element operatively connecting the drive head to the tool tip, said stroke driving mechanism acting upon said drive head to force the marking tool towards the workpiece;
- and
- at least one counter-support located opposite the marking tool and fixed in place on a side opposite of a marking surface of the workpiece,
- wherein, when said apparatus has a workpiece disposed between the marking tool and the counter-support, the marking tool is operatable to be pressed onto or into a marking surface of the workpiece against a restoring force of the elastic element, and the marking tool marks the workpiece while the workpiece is translated in its plane.
An apparatus for marking a sheet-shaped workpiece, said apparatus comprising:
- a punch press, said punch press having a stroke driving mechanism;
- at least one marking tool fixed in place in a punch holder in the punch press, the marking tool having a drive head, a marking tool elastic element, and a tool tip, said marking tool elastic element operatively connecting the drive head to the tool tip, said stroke driving mechanism acting upon said drive head to force the marking tool towards the workpiece, the elastic element cooperatively associated with the stroke driving mechanism to provide an exactly defined contact pressure force between the tool tip and the workpiece;
- and
- at least one counter-support fixed in place on the side of the workpiece located opposite the marking tool, with a workpiece being disposable between the marking tool and the counter-support,
- wherein, when said apparatus has a workpiece disposed between the marking tool and the counter-support, the tool tip is operatable to be pressed onto or into a marking surface of the workpiece against a restoring force of the elastic element, and the marking tool marks the workpiece while the workpiece is translated in its plane.
A method for marking workpieces on punch presses, wherein a marking tool having a tool tip is forced by means of a punch stroke onto or into the surface of a sheet-shaped workpiece, which is displaceable in its plane, comprising:
- providing a punch press having a stroke driving mechanism for performing a punch stroke;
- placing the tool in a marking position by performing a punch stroke, thereby forcing the tool tip onto or into the surface of a workpiece;
- maintaining the tool in the marking position;
- displacing the workpiece corresponding to contours of a shape to be marked while the tool is in the marking position;
- and
- moving the tool away from the workpiece.
