Definitions
- the invention relates to a device for severing endless profiles with a longitudinal axis, especially of extruded ones Plastic profiles, with a knife pointing in the direction of movement of the knife towards the profile and essentially perpendicular to the longitudinal axis is movable.
- DE 298 08 312 U1 therefore discloses a separating device which is equipped with a knife. This is guided in a frame, the side parts of the frame can be completely folded away. The knife is moved by a cylinder and can therefore not follow a movement profile.
- the invention is therefore based on the object of further developing the generic separating device which is equipped with a knife in such a way that it becomes possible to carry out a reproduced separating process. Furthermore, the aim is to ensure that the separation point has no bulge and that the profile has a perfect quality at the separation point.
- the achievement of the object by the invention is characterized by means (3, 4) for bending the profile (2) along its longitudinal axis (L) in the sectional area of the profile (2), the means (3, 4) by the bend in the generate a tensile stress on the area of the profile (2) facing the knife (5).
- the invention is based on the knowledge that in previously known Separating devices by the knife penetrating the profile is clamped with the profile lying on top, since not - as with one Saw - material is cut out, so there is no space for the knife.
- the invention counteracts the resulting clamping force.
- the means causing a bend (3, 4) such a bias on the side of the profile that the Knife is facing that the profile in the cutting area is no longer straight but by the pre-stress at an angle ( ⁇ ) is kept smaller than 180 °, for example between 150 ° and 180 °, before the cutting knife penetrates the profile.
- the means (3, 4) preferably consist of at least two hold-down devices (3) which rest on one side of the profile to be cut (2), as well as at least one increase (4) on the other side of the profile (2).
- the hold-down devices (3) are on the side of the profile (2) facing the knife (5). It can also help of cutting can be provided that the increase (4) in Area of the knife (5) is interrupted.
- the knife (5) is advantageously driven by a drive unit (10) moved, with particular thought of a servo motor with which a precisely controlled movement of the knife is possible.
- the design the drive unit as a servo motor therefore offers the advantage of a quick and precise control of the knife; the control of the knife can be integrated into the overall control of the extrusion process become.
- Another advantage of the digitally controllable servo motor is that that a speed profile of the knife can be driven because the cutting speed has a significant impact on quality who has separation.
- the course of the cut is further improved in that the first contact of the knife (5) with the profile (2) on an edge (6) of the profile (2); this reduces the cutting force required.
- the knife (5) is perpendicular to the longitudinal axis (L) of the profile (2) and perpendicular to the direction (R) of the knife (5) on the Profile (2) to an angle ( ⁇ ) of between 5 ° and 35 °, preferably at 25 °.
- the cutting edge (7) of the knife (5) in Direction (R) of the movement of the knife (5) on the profile (2) at least has two stages (8, 9).
- the angle ( ⁇ ) between the direction (R) of the movement of the knife (5) towards the profile (2) and the cutting surface in the area the step (8) is greater than the angle ( ⁇ ) between the direction (R) of Movement of the knife (5) towards the profile (2) and the cutting surface in the area of level (9).
- a profile can be separated without cutting during the extrusion process.
- the whole Device is mounted on a carriage which, during the actual cutting process is carried out, the clamped, i.e. pre-tensioned, Profile, at extrusion speed via a drive (here can e.g. an electric or pneumatic drive can be selected) emotional.
- a drive here can e.g. an electric or pneumatic drive can be selected
- the device 1 is shown schematically in FIG.
- the knife 5 is inserted in a receptacle and guide 12, which is mounted on a movable table 11.
- the hold-down devices 3 are also attached.
- To the knife 5 for the cutting process Moving in the direction R towards the profile 2 is a drive unit 10 mounted under the movable table 11.
- the device 1 is housed in a security housing 13.
- the whole Unit can be integrated into the extrusion line so that the profile 2 through a cutout 14 of the separating device 1 can. After a predetermined supply, this can be done using appropriate Measuring devices or determined after a certain time, the hold-down devices 3 are actuated, e.g. via one or more pneumatic cylinders.
- This hold-down 3 press the profile 2 against the movable Table 11. Due to the increase 4, the profile becomes a bending moment. This happens - as is clear from the Fig. 1 emerges - such that the part of the profile 2, the knife 5th is facing, is subject to tensile stress. Expressed differently: The hold-down 3 and the increase 4 make the profile 2 forced brought out of its stretched, flat position and partially under an angle ⁇ is kept smaller than 180 °. Now via the control The cutting process is released by means of the drive unit 10 driven knife 5 executed. Profile 2 is made by driving back the hold-down 3 and also by retracting the Knife 5 released again. The separated profile part is replaced by a removed further recess 14, for example with a gripper, which takes over the automatic stacking of the profiles, the table becomes 11 promoted to its starting position while feeding for the next Cut is already done.
- FIG 2 is a perspective schematic view of the cutting unit to see.
- the holder is on the knife receptacle and guide 12 13 attached to the hold-down device 3 in such a way that this without great disassembly work, for example, can be folded away to be very easy to get to the knife 5, e.g. switch.
- the increase 4 is very clearly shown, over which the Prestressing of profile 2 after pressing it down by the hold-down device 3, not shown extended here, is generated.
- the angle ⁇ of the knife 5 the cutting process begins at one Edge 6 of profile 2.
- the extract from device 1 shown in FIG. 3 shows the knife 5 with the required angle ⁇ to start the profile 2 at the Cut edge 6.
- FIG. 7 An enlargement of the cutting edge 7 of the knife 5 can be seen in FIG. This clearly shows the different sizes of the two angles ⁇ and ⁇ of the two stages 8 and 9 of the cutting edge 7, the one homogeneous transition from the tip of the cutting edge 7 to the flanks of the Allow knife 5.
- the notch effect of the hitting profile 2 Knife 5 is hereby reduced.
