Definitions
- the invention relates to a device for the extrusion of curved extrusion profiles, the extrusion profile being formed in a die upstream of a counter beam of an extrusion system and then curved or bent by the action of external forces and separated into partial lengths in the press flow, which are transported away in the press outlet under the action of cooling.
- the discharge device is determined depending on the production program. So when pressing bars, profiles, tubes and hollow profiles, the facilities for straight pressing are designed, while for the production of wires, the system for pressing in the downstream reel must be designed.
- extrusion presses for straight extrusion of the profiles there is, for example, a non-driven roller table piece behind the counter beam.
- the roller table section can be extended to the side to make room for wire feed channels. This is followed by a driven, lowerable roller table with cast plates arranged between the driven, lowerable rollers.
- the rollers are lowered after the pressing and consequently the pressed product or extruded profile is placed on the plates or the support table. From this position, the removal then follows in the usual way.
- a drum rotating about a horizontal axis is known for the removal of extruded profiles that have just been pressed, the circumference of which has a uniform distribution of several profile receiving devices, each of which, on the one hand, has a pressed extruded profile in the course of the rotational movement takes over behind the extrusion press and on the other hand passes it opposite a drain device.
- the profile Receiving devices of the drum are designed at the same time for cooling the extruded profiles.
- the invention has for its object to provide a generic device that allows removal without adverse effects on the one hand the process and operation and on the other hand the cut, one-sided or alternately curved extruded products.
- a rotary table is arranged in the press outlet for taking over the curved extruded profiles.
- the turntable according to the invention allows an extremely variable and changing Batch sizes of the manufacturing process, which is anyway designed for the operating weight of the block to be pressed in numerous partial lengths, can be achieved. This is because the turntable itself can be cycled or run continuously and the curved extruded profiles can be used individually one after the other or in parallel next to each other. This can be done, for example, with the aid of a multi-axis handling robot or the like, for example integrated ejectors or lifters. Furthermore, the diameter of the rotary table enables adaptation to the curved contour of the pressed extruded profiles to be accommodated from the outset.
- a preferred embodiment of the invention provides that cooling devices are provided above and / or below the turntable. If the curved extruded profiles are also advantageously assigned cooling devices laterally, intensive cooling with distribution over the entire cross section of the extruded profile can be achieved. This enables uniform cooling without warping, so that the pressed curvature or geometry of the extruded profiles is maintained.
- a free passage of the cooling medium preferably air
- the cooling devices arranged below the turntable can be achieved from the cooling devices arranged below the turntable to the stored extruded profiles. These are then largely unhindered in the coolant flow.
- the cooling devices are grouped together in zones, advantageously arranged in segment-like housings.
- the housing segments having all the connections then only need to be connected to the central coolant supply source.
- Suitable nozzles are, for example, conventional flat or perforated nozzles which can be arranged offset and / or crossed. Centrifugal or axial fans enable cheaper cooling.
- the division into cooling zones, the diameter of the turntable advantageously immediately specifying the length of the cooling zone, as in the radian measure of 45 ° allows any choice of cooling options, e.g. in the case of smaller extruded profiles, the use of fewer cooling zones or lower cooling capacities.
- the cooling zones or their nozzles can optionally be aligned axially at the top and / or bottom to either the inside or outside diameter or the mean diameter and radially to the inside and / or outside diameter of the curved extruded profile.
- the turntable has at least one loading and one unloading station, which can be provided opposite or next to one another.
- a combined loading and unloading station can advantageously be formed, preferably in the case of extruded profiles with double lengths, i.e. for example, a radian of 90 ° instead of 45 °.
- the cooling devices are designed such that they can be raised and lowered so that, in the case of a combined loading and unloading station, a housing or segment can be raised to an out-of-operation position for loading.
- a further advantageous embodiment of the invention provides air discharge lines connected to the turntable. This allows the air draft present above the center of the rotary table with chimney effect to be used to utilize the waste heat, for example for feeding in or for supplying ovens, such as an aging, a die preheating or a block heating oven.
- the turntable can be combined with a straight run-out roller table. It is therefore also possible to operate the extrusion press for straight extrusion. Because only the run-out roller table needs to be retracted tangentially or immersed between the spokes into the stationary rotary table. This results in the simple retrofitting or integration of a turntable in existing systems.
- Figure 1 is a top view of an extruder with a rotating table arranged in its outlet, shown schematically.
- FIG. 2 shows a perspective overall view as a detail of a turntable designed with cooling segments in combination with a straight run-out roller table equipped with cooling devices for use in the case of extruded profiles which have just been pressed;
- Fig. 3 shows schematically as a detail the arrangement of cooling devices divided into zones for distributing the cooling medium over the entire cross section of an extruded profile.
- a block 2 to be pressed is fed to an extrusion press 1 shown in FIG. 1 by means of a loading device 3.
- the extruded profile 4a or 4b which is pressed out by a shaping die, thus exemplified for two different radii, emerges from the counter beam 5 and reaches an im Press outlet I arranged, around its vertical axis 6 cyclically or continuously moving rotary table 7.
- the curved extruded profiles 4a, 4b are produced with a curvature toward one side that is constant with respect to the straight-pressing direction 8.
- a guide tool indicated schematically by an arrow 9, which acts on the strand accordingly behind the counter beam 5 and which can interact with an upstream radius sensor (not shown).
- the partial lengths of the curved extruded profiles 4a and 4b are separated by a separating device in the pressing direction 8 in front of the extruder 1, e.g. a pair of scissors, cut to length, then taken over by a multi-axis handling robot 10 and placed on the turntable 7, possibly in suitable profile receptacles (not shown) (e.g. mesh or mesh, clamping elements or the like).
- the turntable 7 is designed with radially arranged spokes 11 provided with a radian measure of approximately 45 °. On each two adjacent spokes 11 there is a curved extruded profile 4; Although an assignment with only three curved extruded profiles 4 is shown in FIG. 1, the handling robot 10 will advantageously cover each gap between adjacent spokes 11 successively with extruded profiles individually one after the other or lying parallel to one another.
- the rotary table 7 has several individually below its spokes 11 as well as above with simultaneous lateral alignment to the curved geometry of the extruded profiles 4 or 4a, 4b assignable and deactivatable cooling zones 14a to 14f; in deviation from the example shown, a closed, ie over 360 ° cooling zone arrangement can also be provided.
- the cooling zones 14a to 14f are of modular, segment-like construction and have successively numerous flat or perforated nozzles 17 in the upper and lower segment housings 15 and 16 (see FIG. 2), which are supplied with air, for example, by fans 18 indicated in FIG. 3 , In Fig.
- FIG. 2 is also indicated extremely schematically that air discharge lines 19 can be connected to the turntable 7 for waste heat.
- the double arrow 20 also shown in FIG. 2 indicates that at least the upper segment housing 15 adjacent to the loading zone with its cooling devices 17 or 17a, 17c can be raised and lowered in order to press this segment housing during pressing operation with double the length of the extruded profiles for loading into one To be able to move out of service position.
- the cooling diagram shown in FIG. 3 shows that in the cooling zones 14a to 14f cooling devices 17a or 17b or 17c are formed above or below or laterally to the extruded profile 4.
- the extruded profile 4 or 4a, 4b can thus be cooled uniformly from all sides with largely equal distances between the flat or perforated nozzles of the cooling devices 17a, 17b and 17c.
- the combination of a turntable 7 with an outfeed roller table 21 during the operation of the extrusion press 1 (cf. FIG. 1) for pressing out straight extrusion profiles, not shown, is shown as an alternative system concept.
- the turntable 7 is not driven; Rather, it has been aligned so that the run-out roller table 21 can be moved tangentially into the turntable 7 from a non-operating position, the spoke 11 being immersed in a roller table gap in the exemplary embodiment.
- the extruded profiles to be cooled and to be cooled are provided from below and thus in the run-out roller table 21, flat and / or perforated nozzles 117 and nozzles arranged in hoods 22 from above (nozzles 117a) and laterally (nozzles 117b).
- nozzles 117a flat and / or perforated nozzles 117 and nozzles arranged in hoods 22 from above (nozzles 117a) and laterally (nozzles 117b).
