Abstract

A device for partially removing the coating of a metal plate includes a die and a punch which together form a gap through which the metal plate is fed. The device also includes a drive for generating a movement of the die and the punch relative to the metal plate. The die has a protruding blade on the its surface facing the metal plate. A cutting edge of the blade extends in a direction opposite to the movement direction of the metal plate. The device further includes a pressing device for pressing together the die and the punch. The punch includes a roller which rolls on the metal plate surface opposite the blade.

Claims

1. A device for partially removing the coating of a metal plate, the device comprising the following features:

a die and a punch which together form a gap through which the metal plate is fed;

a drive for generating a relative movement between the die and the metal plate and between the punch and the metal plate;

the die having a projecting blade on its surface facing the metal plate, a cutting edge of said blade extending in a direction opposite to the movement direction of the metal plate;

a rotary drive for rotating the die and the punch in a direction of the cutting edge;

a pressing device for pressing together the die and the punch;

the punch having a roller which rolls on the metal plate surface opposite the blade.

2. The device according to claim 1, wherein the die and the punch are stationary and can be rotated around a common axis.

3. The device according to claim 1, wherein the roller is elastically supported or consists of an elastic material such as hard rubber.

4. The device according to claim 1, wherein the die has a convexly curved upper contact surface.

5. The device according to claim 4, wherein the die is a cylindrical body arranged coaxially to the roller.

6. The device according to claim 5, wherein the die is a hollow cylinder.

7. The device according to claim 1, wherein the die has a bore for chip discharge, the inlet of which is located in the region of the blade and the outlet of which is connected to a chip discharge device.
