    The invention relates to a device for cutting workpieces or components comprising a transmission having a first transmission input and a transmission output, a first drive which is connected to the first transmission input, and an output connected to the transmission output for transmitting a rotational movement to a separating tool , according to the preamble of claim 1.
    The prior art uses different separation technologies for different purposes and materials, including cut-off grinding with a cut-off wheel and sawing with a circular saw blade. Applications of these technologies can be found, for example, in steel mills or similar areas where a wide range of material grades occurs and must be processed. For example, some materials such as steels, stainless steels or other metals are more suitable for cutting, while other materials are better for sawing, also for cost reasons. Due to the different materials, different machines with different cutting tools, cutting speeds, etc. must be used and replaced again and again. This causes a great deal of effort, long waiting times and thus high costs.
    The aim of the present invention is to provide a separation device which does not have these disadvantages and by means of which the switchover from one separation technology to another separation technology, e.g. From cutting on saws, can be done much faster and cheaper. The advantages of the individual separation technologies should be retained.
    This object is achieved with a separation device mentioned above in that the transmission comprises a second transmission input, which is connected to a second drive, and a switching device, the transmission output in a first position with the first transmission input and in a second position with the second Transmission input couples, with a
    Game setting device for adjusting the game in the rotation transmission between at least one of the drives and the output is provided.
    The invention provides a hybrid separation device that has different modes of operation and thus combines different separation technologies. The separator has a common output, i. the output is driven either by the first or second drive. Converting from one cutting process (sawing) to another (cut-off grinding) is particularly easy. By the switching device of the appropriate drive or the associated gear train between the respective drive and the switching device is selected. In addition, at most still the drive flange is changed and a saw blade unit raised or lifted. With the Spieleinstelleinrichtung the required game (clearance - not clearance) set. It has been shown that not only the speed and the torque are decisive for different separation methods, but also the play in the rotational transmission between the respective drive and the output or separating tool. Therefore, the Spieleinstelleinrichtung allows only the integration of different separation processes in one and the same separator. Due to the variable clearance preferably between switching device and output can u.a. the different shock and vibration excitation are taken into account in different separation technologies. In particular, when sawing the life of the cutting tool can be increased thereby. In addition, it is prevented that impacts lead to damage in the gearbox or in the drive. At the same time it is ensured that the required backlash-free adjustment is made possible during sawing.
    The independent drives (motors) may already be designed for the respective separation method, e.g. in terms of speed, torque, power, etc. In the first position, the first drive is selected, while the second drive is decoupled from the common output. In the second position, the second drive is selected, while the first drive is decoupled from the common output.
    It is preferred if the oil lubrication for the transmission is also switched simultaneously with the switching device, i. it can only be supplied with oil that is currently in operation.
    Therefore, the invention also allows the integration of two entirely different separation methods such as the cut-off (with a cut-off wheel) on the one hand and sawing (with a circular saw blade) on the other hand in a separation device. In order to switch from one separation method to the other, only the switching device is to bring in the other position, replace the cutting tool (ie the cutting wheel is replaced by a circular saw blade), possibly even changed the drive flange and a saw blade unit lifted or lifted and adjust the lash adjuster accordingly.
    The switching device can be switched either automatically or manually by an operator. The same applies to the Spieleinstelleinrichtung, the game is preferably continuously adjustable via an actuator.
    Preferably, the Spieleinstelleinrichtung acts on the transmission output shaft, so that the game is changed in the rotational transmission between the transmission output shaft and the transmission output shaft in the rotation transmission preceding shaft or preceding rotary element. In this way, shocks and vibrations (especially when sawing) can not be transmitted further into the gearbox interior.
    It has been shown that in (cold) circular saws low speeds (about 25-60 rpm), high torque (about 20,000 Nm) and a backlash-free gear deliver particularly good results. In addition, the saw blade should be cooled, lubricated and advantageously meadow laterally guided or attenuated. On the other hand, during high speed cutting (about 1,200-3,000 rpm), lower torques, and a non-backlash-free gearbox are required. In addition, the cutting wheel should be measured and readjusted due to the progressive wear.
    A preferred embodiment is characterized in this sense by the fact that in a first mode of operation of the device, the cutting tool is a circular saw, the switching device is in the first position and the Spieleinstelleinrichtung assumes a low-backlash, preferably play-free position, and that in a second
    Operating mode of the device, the cutting tool is a cut-off wheel, the switching device is in the second position and the Spieleinstelleinrichtung assumes a position in which the game is greater than in the first mode. The torque provided at the output in the first position of the switching device can be, for example, at least 10,000 Nm, preferably at least 15,000 Nm, and in the second position of the switching device at most 5000 Nm, preferably at most 3000 Nm. Thus, ideal parameters for sawing (i.e., high torques) on the one hand and cutoff grinding (i.e., low torques) on the other hand are achieved.
    The separator may e.g. be movably mounted on a platform or a boom. Corresponding drives for automatically cutting the separator during cutting may be provided.
    A preferred embodiment is further characterized in that the transmission ratio between the first drive and the output and the transmission ratio between the second drive and the output by a factor of at least 10, preferably at least 20, are different from each other. As a result, the required speed difference between the different separation processes (cutting and sawing) can be achieved. For cutting, much higher speeds are used.
    In the practical execution, the
    Spieleinstelleinrichtung be integrated in the transmission, resulting in a compact and space-saving design that combines the most important settings in a gear unit.
    A preferred embodiment is further characterized in that at least two intermeshing gears are provided with mutually parallel axes of rotation, wherein one of the gears is axially displaceable relative to the other gear, and the Spieleinstelleinrichtung an actuator for axial displacement of one of the gears relative to the other gear Setting the game includes. Due to the relative to each other displaceable arrangement of the meshing gears, the game can be adjusted in the rotation transmission in a particularly simple manner and already in the transmission. The displacement preferably takes place in such a way that the shaft on which the relevant toothed wheel is seated is displaced axially. A preferred embodiment is characterized in particular by the fact that the meshing gear wheels each have a conical toothing (bevel helical gear transmission) or that at least one of the toothed wheels has a toothing which changes in the axial direction. The game setting is thus carried out either by conical delivery or by shifting the engagement in a toothed region having different geometric properties.
    A preferred embodiment is characterized in that the Spieleinstelleinrichtung comprises an actuator, which is preferably hydraulically, pneumatically, electrically, mechanically or electro-mechanically actuated. This allows the game to be set automatically and reproducibly.
    A preferred embodiment is further characterized in that the output is connected to a tool holder, preferably in the form of a clamping flange, and that the cutting tool held by the tool holder is a circular saw or a cut-off wheel.
    Preferably, the apparatus further comprises a cooling and / or lubricating device, which is removable as a unit or movable away from the working area or from the separating tool of the device. This facilitates the conversion to a separation technology that no cooling or
    Lubrication required (cut-off grinding).
    In the following, preferred embodiments of the invention will be described in more detail with reference to the drawing. It shows
    1 shows an embodiment of a separating device according to the invention,
    Fig. 2 shows a separation device according to the invention in a schematic representation.
    Fig. 1 shows a device 9 for cutting through workpieces or components. This has a transmission 10 with a first transmission input 11, a second transmission input 12 and a transmission output 13. A first drive 1 is connected to the first transmission input 11 and a second drive 2 is connected to the second transmission input 12. An output 3 is connected to the transmission output 13 and serves to transmit the rotational movement to a separating tool 4 (FIG. 2).
    The transmission 10 has a switching device 5, which the transmission output 13 in a first position with the first
    Transmission input 11 and in a second position (shown in Fig. 1) coupled to the second transmission input 12.
    The switching device 5 consists in the illustrated embodiment of two gears, which are axially displaceable together according to the drawn in Fig. 1 in the switching device 5 double arrow. By axial displacement can be switched between the first drive 1 and the second drive 2 by a first of the two gears with a gear of the first transmission input 11 is engaged or disengaged, and a second of the two gears with a gear of the second Transmission input 12 is disengaged or engaged.
    In addition, the device 9 has a
    Game setting device 6 for adjusting the game in the rotation transmission between at least one of the drives 1, 2 and the output 3, which will be explained below. The Spieleinstelleinrichtung 6 is formed in the illustrated embodiment by two meshing gears 7, 8, wherein for adjusting the
    Game in the rotational transmission of one of the gears 7 relative to the other gear 8 is axially displaceable, which is indicated by the drawn in the game setting 6 double arrow in Fig. 1. The axes of rotation of the meshing gears 7, 8 are parallel to each other. In this case, the meshing gears 7, 8 each have a conical toothing (as indicated in Fig. 1), or at least one of the gears 7, 8 may have a changing in the axial direction of the toothing. An actuator of the lash adjuster 6, e.g. is hydraulically, pneumatically, electrically, mechanically or electro-mechanically actuated, serves for the axial displacement of the two meshing gears 7, 8th
    In a first mode (sawing) is used as a cutting tool 4, a circular saw. The switching device 5 is brought into the first position and the Spieleinstelleinrichtung 6 is brought into a low-backlash, preferably play-free position. In a second operating mode (cut-off grinding), a cut-off wheel is used as cutting tool 4. The switching device 5 is brought into the second position and the
    Backlash adjustment device 6 is brought into a position in which the game is greater than in the first mode.
    The transmission ratio between the first drive 1 (here: the saw drive) and the output 3 and the transmission ratio between the second drive 2 (here: the cutoff drive) and the output 3 are preferably different from one another by a factor of at least 10. As a result, lower speeds are achieved in the case of sawing than during cutting. The speeds of the first drive 1 can be adjusted by a belt drive 15 upstream of the transmission 10 and further reduced by the transmission 10.
    The output 3 is connected to a tool holder 14, preferably in the form of a clamping flange, and may, as mentioned, e.g. a circular saw and a cut-off wheel as a cutting tool 4 wear (Fig. 2).
    Preferably, the device 9 further comprises a cooling and / or lubricating device (not shown in FIGS. 1 and 2) which can be removed as a structural unit or moved away from the working area of the device 9 or from the separating tool.
    Fig. 2 further shows a platform on which the device 9 is mounted and preferably moved by additional drives.
    In the method for cutting workpieces or components with a device 9 according to the invention, the corresponding operating mode is initially selected (sawing or cut-off grinding). In this case, the switching device 5 is brought into the first position (sawing) or second position (cutting loops). When sawing the Spieleinstelleinrichtung 6 low-play or switched free of play. In the case of cut-off, the backlash adjuster 6 is switched so that there is sufficient play in the rotary transmission, but in any case greater play than when sawing.
    The invention thus provides a separation device by means of which the changeover from one separation technology to another separation technology, for example from cutoff to sawing, can take place much more quickly and cost-effectively, wherein the advantages of the individual separation technologies can be maintained.
