Definitions
- the invention relates to a shredding disk for a shredding roller of a shredding device, with a base body and with at least one ripper tooth, an undercut recess being provided in the area of each ripper tooth, in which an exchangeable cutting insert is fixed in the working position with a cutting edge pointing in the direction of rotation.
- Such a shredding disk can be found, for example, in EP-A 468 338.
- the recesses in the base body represent undercut grooves that extend perpendicular to the disk and have radially outwardly tapering contact surfaces.
- Dovetail-shaped cutting inserts are inserted into these, on each of which the cutting edge is formed. Replacing the inserts presents problems because the inserts have to be inserted from the side. However, there is little or too little space for this in the case of comminution rollers composed of a multiplicity of comminution discs arranged in series.
- an easier replacement is achieved in that the cutting insert can be inserted into the undercut recess from the circumference of the base body in a mounting position rotated relative to the working position and rotated into the working position.
- a first edge which lies in the circumferential surface of the comminution disk, serves as a pivot axis about which the cutting insert can be tilted after loosening a fastening screw. From the- The contact surface of the recess with this first edge may nowhere be greater than between the two edges, and may therefore remain the same or decrease discontinuously or continuously.
- the contact surface preferably runs in the form of a circular arc with the distance remaining constant and continuously decreasing, in which case the center point lies either in the first edge or within the recess.
- a circular contact surface forms a particularly good support for the cutting insert, which is exposed to very high loads, since the direction of force transmission to the base body is at a point perpendicular to the contact surface.
- the cutting insert is preferably fixed on the one hand by a stop of the base body acting counter to the cutting edge in the region of the first peripheral edge and on the other hand by a fastening screw which is arranged in the cutting or tearing tooth.
- the contact surface of the recess of the base body has at least one groove and the contact surface of the cutting insert has a web engaging in the groove per groove.
- 1 shows a section of a shredding disk with a first embodiment of a cutting insert
- 2 shows a plan view of the comminution disk in the absence of a cutting insert
- FIG. 3 shows a representation according to FIG. 1 when the cutting insert is removed
- FIG. 4 shows a detail of a comminution disk with a second embodiment of a cutting insert.
- Comminution disks are arranged next to one another on a drive shaft and form a comminution roller of a comminution device, which can be used in particular for waste.
- This preferably comprises at least two comminution rollers, the comminution disks of which mesh with one another.
- Each shredding disk has a base body 1, from the circumferential side of which at least one tooth 2 protrudes, which has a cutting edge 7 in the direction of rotation.
- the cutting edge 7 is formed on a cutting insert 5 which is interchangeably fastened in a recess 3 in the base body 1.
- the recess 3 has an abutment surface 4 which, according to FIGS.
- the fixing of the cutting insert 5 is achieved on the one hand by the stop 11 and on the other hand by a screw 10 which is inserted into the tear tooth 2 from the side opposite the cutting edge 7.
- the cutting insert 5 has an abutment surface which corresponds to the abutment surface 4 and therefore likewise has an arc-shaped area and a closing inwardly recessed area which interacts with the stop 11.
- the contact surface 6 is provided with a web 9 which engages in the groove 8.
- the circular contact surface 4, the groove 8 and the web 9 provide very good support for the cutting insert 5 in all directions. If the cutting insert has a larger width, it can carry a plurality of cutting edges 7 which are spaced apart from one another in the axial direction.
- the recess 3 is rounded in a square shape, the first edge 12 also acting as a pivot axis in this embodiment, and the distance a between the contact surface and the first edge 12 decreases unevenly.
- the distances a form a monotonically decreasing sequence in the two embodiments, in the embodiment according to FIGS. 1 to 3 the sequence is even a strictly monotonously decreasing sequence.
