Definitions
- Cutting device with at least two cutting elements
- the present invention relates to a cutting device with at least two cutting elements, in particular for the nose cutting of split beaver bricks.
- so-called extruded roof tiles are produced by an extrusion press as a flat, continuously emerging strand, the so-called split beaver tiles having at least one so-called nose, which is used to hold the tile on the roof cone to hold on to the structure.
- the roof tiles are degenerate in one dimension. They therefore form flat elements that can be treated practically as two-dimensional structures. Their treatment entails a substantial number of disadvantages, since they cannot be manufactured in the same way as the three-dimensional bricks.
- Cutting devices are known for the partial removal of such nasal strands, but they do not take the following points into account: if the cutting device is arranged on the die of the extrusion press itself, monitoring of the activity of the cutting device is practically excluded. For example, it cannot be checked whether the noses are notched exactly.
- the present invention aims to provide a cutting device which is a fixed part of the Extrusion line is arranged and yet easy to adjust, monitor and work safely.
- Such a cutting device is characterized by one of the claims.
- FIG. 1 shows the front view of a three-dimensional, cross-cut double-brick structure coming from the extrusion press, each with two opposing nose strands and two synchronized, opposing cutting devices,
- FIG. 4 shows the cutting scissors connected to the actuating device according to FIG. 3 in plan view with cut actuating shafts according to section line IV-IV of FIG. 2,
- FIG. 5 is a top view of the actuating device for the cutting device analogous to FIG. 3 for the closed position of the cutting forks
- 6 is a plan view of the cutting scissors of FIG. 5, analogous to FIG. 4,
- Fig. 7 shows a section of the transition region of the actuating shafts with the one cutting fork.
- FIG. 1 shows the front view of a double-strand roof tile 1 which is known to be cross-cut into corresponding brick blanks by known cutting devices.
- the sides of such a brick blank are formed by two split beaver bricks 2 and 3 with their base surfaces opposite one another, the narrow broad sides 5 and 6 of which can be seen.
- the two bricks 2 and 3 are connected by connecting webs 8.
- notches 9 are provided which, after firing, enable the split beaver bricks 2 and 3 to be separated from the webs 8.
- they are usually provided with one or two noses.
- these lugs extending from the broad end towards the front rounding side are formed in the sense that the nose strands 11 and 12, which extend over the entire length of the brick, are separated from the underside of the brick blank except for the remaining lugs .
- Each of the two cutting devices 14 and 15 is designed as a double cutting device, since each of the two nose strands 11 and 12 cuts through that and separate.
- Fig. 1 the left and right cutting fork is open in dashed lines, i.e. visible in the cutting position, while it appears in full position in the closed position 18.
- the cutting forks are actuated by means of a drive 20 or 21, which drives are normally designed as pneumatically actuated cylinders / piston assemblies.
- Fig. 2 the cutting device is shown in side view.
- One cutting fork 25 with a cutting wire 26 can be seen, which is clamped in two wire holders 27.
- the two cutting forks 25 are driven on the one hand by a hollow shaft 29 on which the one cutting fork 25 and on the other hand an inner shaft 30 with a head 31 to which the other cutting fork 25 is fastened by means of a welding 32.
- the inner shaft 30 which is inserted in the hollow shaft 29 and the hollow shaft 29 itself are mounted as a unit in a swivel shaft bearing 33.
- the two shafts 29 and 30 are pivoted in the opposite direction of rotation by means of a swivel rod quadrilateral 37 which swivels the cutting forks into their open position with respect to a longitudinal displacement axis 38 in the sense of FIG. 3 or in their opening position according to FIG. 5 Closed position, as can be seen in FIGS. 4 and 6.
- the individual levers of the swivel linkage quadrilateral 37 are connected to one another via ball joints 39.
- the pivot axis of the two shafts 29 and 30 is designated 40.
- About a yoke 41 is the swivel rod square 37 connected to a piston rod 44 of a piston in a pneumatic cylinder 43, the cutting device being in its cutting position according to FIG.
- the described drive of the cutting forks is very simple, since they are moved into a closed or open position by an opposite movement of the shafts 29 and 30.
- the cutting device is otherwise, in contrast to the reciprocating Strand cutters, provided as a fixed part, so that the difficulties encountered when moving such machining parts are avoided.
- the cutting forks 25 with the cutting wires 26 can be preceded by a guide wedge, which secures the corresponding distances and thus ensures that the separation of the nose strands 11 and 12 takes place on the back surfaces of the bricks and not above or in them.
- all moving parts can be adjusted, including the fork opening of the cutting forks 25, by adjusting the pivot position of the shaft 29 relative to one another relative to the clamping heads 46 of the corresponding pivot tabs of the pivot linkage rectangle 37.
- the lifting height or length of the piston rod 44 can also be changed in the retracted and extended state, and the relative position of the two cutting forks 25 to one another.
- the cutting device described hereby enables the hanging lugs in double-strand roof tiles to be produced in a simple and safe manner.
