Definitions
- the invention relates to a device for cutting a preferably thick-walled extruded tube, with at least one cutting tool and a receiving unit for the cutting tool, wherein the cutting tool is movable radially to the extrusion axis and rotatable about other means around the pipe to be cut off to cut the pipe wherein the separating tool is in operative connection with a ring element and the ring element is movable via an axial drive and by means of an adjusting the penetration depth of the separating tool and the travel can be determined.
- flying saws For cutting extruded tubes usually so-called flying saws are used, wherein a circular saw blade is brought either from below (underfloor saw), from above (immersion saw) or from the side (cross saw) to the pipe to be sawed, in the cross section of the tube dips in and cuts through the wall thickness in the first step.
- the saw blade In the second step, the saw blade is passed around the pipe to completely cut the pipe.
- the pipe to be cut is clamped during the sawing process;
- the saw carriage or saw carriage then travels synchronously with the continuous extrusion process at the extrusion speed ("flying saw").
- the invention is therefore based on the invention, the known expertise of a generic separation device equipped with a knife to develop such that it is possible to offer a device combines several functions in one component.
- the solution of the problem is in connection with the preamble of claim 1, characterized in that the penetration depth of the cutting tool and the travel over this one axial drive can be determined, with the penetration depth racks are more or less movable.
- the travel and the penetration depth of the cutting tool on one and the same drives realized and thus implemented at least two functions on a part of the device.
- the axial drive is adjustable via pneumatic cylinders.
- the drives over which several functions are realized is thus a pneumatic drive according to the invention.
- the adjustment unit has limit switches by means of which the switching of the direction of movement is initiated.
- the position of the limit switches during manual adjustment can be determined via a scale.
- the adjustment of the limit switch can also be done via an electric linear drive.
- this is controlled via the machine control of the extrusion line.
- the pneumatic cylinder of the axial drive can be an electric drive, for example a servomotor.
- the ring element consists of an inner ring and an outer ring, wherein the outer ring is coupled via a connecting part with the axial drive.
- the ring member can be axially displaced without it being completely rotated, as between the inner ring and the outer ring of the ring member axial forces are transferable.
- the axial movement is transferred from the axial drive to the inner ring via the outer ring and passed on to the first pay bar.
- an axial movement into a radial movement of the separating device can be realized via a drive.
- the radial movement serves as a cutting movement for the separating device Training is proposed to run the ring element as a thrust bearing.
- Fig. 1 shows a typical extrusion line
- Fig. 2 shows the part of the separating device
- Fig. 3 shows the part of the separating device in a different position
- FIG. 4 shows an enlarged view of the adjusting unit.
- FIG. 1 shows a typical extrusion line as used today for profile extrusion, regardless of whether it is for the production of window profiles or pipes. It shows an extruder 1, in which plastic is melted, and is continuously conveyed to the extrusion tool 2 for shaping. This is followed by a calibration and cooling station 3, depending on the profile more cooling stations can be used. After the cooling stations, a trigger device 4 connects. In order to cut off the endless profiles 6 to the desired length, a separating device 5 is then arranged.
- FIG 2 shows a schematic representation of the separation device according to the invention and corresponds to the position 5 as shown in Figure 1.
- a sleeve 14 is arranged with linear guides 22, which is in operative connection with a ring member 29.
- On the Aufhahmearchitecture 15 separating tools 7 are arranged, which are adjusted by means of racks 11 and 12.
- the ring element 29 can be displaced along the extrusion axis 9 in or counter to the extrusion direction 10.
- an axial drive 17 is provided.
- the ring element 29 consists of an inner ring 30 and an outer ring 31 which is coupled via the connecting part 32 with the axial drive 17.
- the drive is a pneumatic cylinder 19 whose direction switching is realized by means of limit switch 21.
- For determining the position of the limit switch 21 in a manual adjustment is a scale 20th
- the forceps 11 and 12 are more or less moved over the pneumatic cylinder 19 and thus determines the penetration depth of the separation tool 7 in the pipe 6 to be cut off. Furthermore, the rotary drive 16 is shown for the receiving disk 15, which rotates the or the separating knife to be cut off the pipe.
- FIG. 3 essentially corresponds to the representation according to FIG. 2. The difference is that the ring element 29 is shown at a different position. About the axial drive 17, the ring member 29 has been moved axially. The outer ring 30 of the ring element 29 is coupled via the connecting part 32 with the axial drive 17. The outer ring 30 transmits the axial forces on the inner ring 31 and moves the ring member 29 along the linear guides 22 and in the extrusion direction 10. The inner ring 31 of the ring member 29 is in communication with the first rack 11 of the separator. By coupling the racks over the block 13, the second rack 12 is simultaneously moved in the radial direction. Since the cutting blade is arranged on the rack 12 via the receiving unit, the lengthening of the pipe, not shown, is made.
- FIG. 4 shows, in an enlarged view, the part of the adjusting unit 18 from FIG. 2, wherein the same parts are marked with the same reference numerals.
