Blade and blade mount for a cutting machine

1. A blade mount for a cutting machine, comprising:

a contact surface for a blade;

a mount section for the blade axially projecting from the contact surface; and

at least one torque transmission element which projects axially from the contact surface, which is radially spaced apart from the mount section, which engages into the blade and in which a receiver for a fastening means is formed for fastening the blade to the blade mount,

wherein the mount section defines an inner space and at least one prefixing pin projects radially into the inner space.

2. The blade mount in accordance with claim 1 ,

in which an internal thread is formed in the at least one torque transmission element for the reception of a screw provided for the screw connection of the blade at the blade mount.

3. The blade mount in accordance with claim 1 ,

in which an axial dimension of the at least one torque transmission element is smaller than an axial dimension of the blade.

4. The blade mount in accordance with claim 1 ,

in which the at least one torque transmission element has an outer contour matched to an associated aperture of the blade.

5. The blade mount in accordance with claim 1 ,

in which the at least one torque transmission element is one of a plurality of torque transmission elements.

6. The blade mount in accordance with claim 5 ,

in which all the torque transmission elements have the same radial spacing from the mount section.

7. The blade mount in accordance with claim 5 ,

in which all the torque transmission elements are arranged evenly distributed along a circular path arranged concentrically with the mount section.

8. The blade mount in accordance with claim 1 ,

in which the mount section is configured as at least sectionally cylindrical and is adapted to an associated circular central opening of the blade.

9. The blade mount in accordance with claim 8 ,

wherein at least one part section of the mount section adjacent to the contact surface forms a fit corresponding to the central opening of the blade and a free end of the mount section has an outer diameter reduced with respect to the part section.

10. The blade mount in accordance with claim 1 ,

wherein the mount section defines an inner space which is open at the end face and which is aligned concentrically with the mount section so that a ring-shaped wall is produced, and

wherein at least one prefixing pin projects radially out of the ring-shaped wall into the inner space.

11. A system comprising a blade mount in accordance with claim 1 , the blade which can be fastened to the blade mount and a handling apparatus for assembling or dismantling the blade at the blade mount, the handling apparatus comprising:

at least one means for the releasable attachment of the handling apparatus to the blade; and

a prefixing element which can engage through a central opening of the blade attached to the handling apparatus and which can be introduced into the inner space of the mount section of the blade mount of the cutting machine

wherein at least one guide for the at least one prefixing pin of the blade mount is provided at a jacket surface of the prefixing element.

12. The system in accordance with claim 11 , wherein the prefixing element is matched to the contour of the inner space.

13. The system in accordance with claim 11 ,

wherein the guide is configured such that it allows a first axial movement of the prefixing element into the inner space, a rotation of the prefixing element into the inner space and a subsequent second axial movement of the prefixing element into the inner space.

14. The system in accordance with claim 13 , in which the guide is configured as a slot guide and comprises an axially extending first groove section and a second groove section adjoining it and extending in the peripheral direction,

wherein the slot guide additionally comprises an axially extending third groove section which extends, starting from the second groove section, in a direction opposite to the first groove section.

15. The system in accordance with claim 13 , in which the guide is configured as a slot guide and comprises an axially extending first groove section and a second groove section adjoining it and extending in the peripheral direction,

wherein the width of at least a portion of the second groove section extending in the peripheral direction is larger than a maximum dimension of the prefixing element.
