    The invention relates to a drive system for a mechanical Umforinmaschine and a mechanical forming machine, which is designed in particular as a crank press, according to the preamble of claim 1 or 10th
    WO 2008/149171 A1 discloses a mechanical forming machine which comprises a drive train, a flywheel drive connected to the drive train and a power take-off connected to the drive train, wherein the flywheel drive comprises a flywheel and a clutch and wherein the clutch comprises the flywheel with a drive shaft the drive train couples. A disadvantage of such forming machines is that only the drive power of the auxiliary drive is available for a pendulum stroke in the return stroke.
    It is an object of the invention to provide a drive system for a mechanical forming machine or a forming machine with two drives, in which or in which in both directions of rotation or in Pendelhubbetrieb for a return stroke, the full drive power is retrievable.
    This object is achieved on the basis of the features of the preamble of claim 1 by the characterizing features of claim 1 and 10, respectively. In the dependent claims advantageous and expedient developments are given.
    In the drive system according to the invention, the flywheel drive comprises in addition to the flywheel and the first ·· Φ ·· Φ · ΦΦ · ♦ ♦ · · · · · · ν · * < * · · «·« Φ · · t * * I · f · · · · · · * »v ·% # 2 ♦ - ···
    Clutch a reversing gear and at least a second clutch, wherein the reversing gear in a first switching position of the two clutches a rotation of the flywheel at an input speed converts into a rotation of the drive shaft in a first direction of rotation or forward rotation corresponding to the input speed corresponding first speed and wherein the reversing gear in a second switching position of the two clutches, a rotation of the flywheel at an input speed converts into a rotation of the drive shaft in a second direction of rotation or reverse direction of rotation with a second speed. With such a drive system, it is possible to drive not only to the auxiliary drive but also to the flywheel or the flywheel drive both in the forward direction of rotation and in the reverse direction of rotation on the drive shaft or drive train. In this way, a pendulum lifting operation of a forming machine is possible, which is equipped with the drive system according to the invention, in which also during operation of the forming machine in the reverse direction, the full power of the drive system is retrievable. However, it is also possible depending on the particular requirement, in each case only the flywheel drive or only the power take-off in the forward direction of rotation or in the reverse direction of rotation. The core of the invention is a drive system in which the flywheel drive is flexibilized in its mode of action in order to be able to perform additional work functions with the drive system on a forming machine.
    In particular, it is also possible to retrofit drive systems of older forming machines in such a way that they are made pendulum-capable by equipping them with a power take-off - if they have not yet been provided with a reverse gear and an additional clutch.
    According to the invention, it is provided that the reversing gear be designed such that at the same input speed, the first speed is equal to the second speed. Such a design makes it possible to operate the drive system independently of the direction of rotation.
    The invention also provides to assist with the auxiliary drive in response to the switching position of the reversing gear, if necessary, the rotation of the drive shaft in their respective direction of rotation. Accordingly, it is possible with the drive system to assist with the auxiliary drive both in the forward direction of rotation and in the reverse direction of rotation supportive.
    According to the invention, it is provided to design the reversing gear as a planetary gear. With such a transmission, it is possible, in particular during the retrofitting, to make optimum use of an installation space which is annular between the drive shaft and the flywheel in a side view in the direction of a longitudinal axis of the drive shaft.
    According to the invention, the two clutches of the flywheel drive are arranged on the drive shaft, wherein the highest one of the two clutches is coupled to the drive shaft. With such a switching double clutch, it is possible to tap from the reversing gear selectively rotating in the desired direction of rotation speed.
    The invention provides, in particular, to couple a ring gear to the drive shaft via the first clutch and to couple a sun gear with the drive shaft via the second clutch. Such an arrangement allows a compact design of the couplings.
    Furthermore, the invention provides to support planet gears of the planetary gear rotatably about axes, which are stationary with respect to an axis of the drive shaft. As a result, defined states of the planetary gear in the two switching positions are ensured.
    According to the invention, in the first shift position of the clutches, the first clutch is closed and the second clutch is opened and in the second shift position of the clutches the first clutch is opened and the second clutch is opened ···· 9999 ···· t · · 9 9 9 ·· ········································································································································································ This ensures that only one tap of the forward direction of rotation or the reverse direction of rotation takes place.
    The invention also provides to support the flywheel freely rotatably mounted on a running sleeve of the planetary gear, wherein the running sleeve itself is freely rotatably mounted on the drive shaft and is further provided to equip the flywheel in particular with an internal gear, which in particular at least one or more radially arranged Planet wheels driving, these planetary gears in particular each drive via a shaft in each case a gear, which in each case drives in particular one connected to the barrel gear. As a result, a compact construction of the planetary gear is guaranteed. Furthermore, it is thereby possible to use for retrofitting the storage of the flywheel for supporting the barrel sleeve and to use the flywheel itself as a ring gear. Through the interposition of the gears connected to the planetary gears via shafts, it is possible to select the gear ratio for the reverse rotation by the selection of the planet or the wheels so that the same speed results for both directions of rotation.
    The Umfornimaschine invention has a drive system according to one of claims 1 to 9 and accordingly has the advantages mentioned with respect to the drive system.
    For the purposes of the invention, a multi-joint drive system is understood, for example, to be a drive system with a 4-unit drive, as used for example in the student's hipro drive and in the "Manual Forming Technology: Fundamentals, Technologies, Machines". {2nd Edition) of the authors Eckart Doege and Bernd-Arno Behrens on the page 753 is shown and described.
    Further details of the invention are described in the drawing with reference to schematically illustrated embodiments 5: "t".
    Hereby shows:
    Figure 1: an inventive drive system in a first switching position of the two clutches;
    FIG. 2: the inventive device shown in FIG
    Drive system in a second switching position of the two clutches and
    Figure 3: the forming machine partially shown in Figure 1 in a schematic view.
    1 shows a schematic view of an inventive drive system 1 in a first switching position A of the two clutches Kl, K2 shown. Here, the first clutch Kl is in a closed position SK11 and the second clutch K2 in an open position SK22. The drive system 1 is designed to drive a forming machine 2, which is completely shown in FIG. 3, which is designed as a crank press 3 and is thus also referred to as a forming machine drive system or crank press drive system. The drive system 1 comprises a drive train 4, which is connected to a flywheel drive 5 and a power take-off 6 and is driven by one of these drives or both drives. The drive train 4 essentially comprises a drive shaft 7, which acts on a crank drive 8, which actuates an upper tool 9, which cooperates with a stationary lower tool 10. Here, a workpiece, not shown, is processed between the upper tool 9 and the lower tool 10. The flywheel drive 5 comprises in addition to a flywheel 11 and the already mentioned first clutch Kl a reverse gear 12 and the already mentioned second clutch K2. The auxiliary drive 6 comprises a servomotor 13 and a third clutch K3, wherein the servomotor 13 can be coupled to the drive train 4 or the drive shaft 7 via the third clutch K3. In English: FIG. 1 shows the third clutch K3 in a closed position SK31, in which the servomotor 13 is coupled to the drive shaft 7. The flywheel drive 5 also includes an electric motor 14, which drives the flywheel 11 by means of a pinion 15. The flywheel 11 is driven by the electric motor 14 in a rotational direction w. In the above-mentioned position A of the clutches K1 and K2, the rotation of the flywheel 11 is transmitted via the closed clutch K1 directly to the drive shaft 7, so that it rotates with the rotational speed of the flywheel in the direction of rotation w about a longitudinal axis L7. The direction of rotation w is also referred to as the first direction of rotation w and the forward direction of rotation w.
    The auxiliary drive 6, which supports the flywheel drive 5, drives the drive shaft 7 also in the direction of rotation w, wherein the direction of rotation and the drive power of the servomotor 13 are electronically controlled. The flywheel 11 is freely rotatably mounted on a running sleeve 17 by means of a flywheel bearing 16, which in turn is freely rotatably mounted on the drive shaft 7 by means of a bearing sleeve bearing 18. If the clutch K3 is opened or, the servo motor 13 is turned off, the drive of the drive shaft 7 takes place exclusively by means of the flywheel drive 5 in the forward direction of rotation w. Of course, it is also possible to open the clutch Kl and leave the clutch K2 in its open position SK22 and the drive shaft 7 or, the drive train 4 exclusively via the auxiliary drive in the direction of rotation w or in an opposite direction of rotation w ', which Also referred to as the second direction of rotation w 'or reverse direction wf is to drive. A single drive via the servo motor 13 is particularly provided for the performance of maintenance. The power flow through the reversing gear 12, which is designed as a planetary gear 19 is drawn from the flywheel 11 with a running on the clutch Kl in the drive shaft 7 dashed arrow line KFA.
    In FIG. 2, the drive system 1 known from FIG. 1 is in a second position B of the clutches K1 and K2 99 99 99 ···· Μ · 9 t · 9 9 9 9 9 9 ··· 9 9 · · ♦ »» * «9 * * ·· 9 • f ··· 9 ^ 9« 9 # 99 99 «V« / * " 999, wherein a representation of the crank drive, the upper tool and the lower tool has been omitted. In the second position B, the first clutch K1 is in an open position SK12 and the second clutch K2 is in a closed position SK21. Thus, there is no direct connection between the flywheel 11 and the drive shaft 7. A power flow from the flywheel 11 to the drive shaft 7 takes place at this second position B now on the drive sleeve 17 and the second clutch K2 on the drive shaft 7. For this purpose drives the flywheel 11th with an annular internal toothing 20 three circumferentially spaced planetary gears 21, of which in the illustration of Figure 2 only one is visible. According to embodiments not shown, it is also provided to equip the drive system with only one planet or two planetary gears or more than three planetary gears. The planetary gear 21 is disposed on a shaft 22 which is freely rotatable about its longitudinal axis 22, but is fixedly supported relative to the longitudinal axis L7 of the drive shaft 7. Via the shaft 22, the planet gear 21 driven by the internal gear 20 forming a ring gear HR of the flywheel 11 drives a gearwheel 23 directly. This in turn drives a gear 24 connected to the running sleeve 17. Thus, the flywheel 11 rotating in the rotational direction w generates rotation of the planetary gear 21, the shaft 22, and the gear 23 in the rotational direction w. Furthermore, the gearwheel 23 rotating in the direction of rotation w generates a rotation of the toothed wheel 24 or of the barrel sleeve 17 in the direction of rotation w '. Here, the barrel sleeve with its gear 24 forms a kind of sun gear SR. Finally, this rotation is transmitted in the direction of rotation w 'of the second clutch K2 on the drive shaft 7, which then rotates accordingly in the reverse direction w' at the same speed as the flywheel. Thus, regardless of the shift position of the clutches K1 and K2, the flywheel 11 always rotates in the direction of rotation w, depending on the shift position of the clutches K1 and K2, rotation of the drive shaft 7 in the forward direction w or rotation of the drive shaft 7 in the reverse direction w '. , A power flow from the
    Flywheel 11 on the drive shaft 7 is shown in Figure 2 with a dashed arrow KFB. Depending on the requirements, the auxiliary drive 6 with its servomotor 13 supports a rotation of the drive shaft in the direction of rotation w '.
    A retrofit an existing Umforromaschine, which already comprises a flywheel drive with a clutch and a PTO, takes place such that an existing flywheel storage forms a bearing for the barrel that on the barrel sleeve 17 a further storage for the flywheel is arranged, - that the existing Flywheel is adapted to the further storage, that for driving the sleeve, the flywheel is provided with an internal gear that planetary gears are arranged in a star-shaped arrangement that the planetary gears are arranged on shafts which are rotatably mounted on the machine frame about its own axis that on the shafts of the planetary gears in each case a further gear is arranged, that act on the shafts of the planetary gears and the planet gears on a sun gear formed by the sun gear and that between the barrel sleeve and the drive train or the drive shaft e Ine second clutch is arranged.
    In FIG. 3, the forming machine 2 according to the invention partially shown in FIG. 1 is shown completely in a schematic view. The drive system 1 is mounted on a machine frame 25, wherein the drive shaft 7 is rotatably supported by the machine frame 25 and wherein a shaft 22 supporting the support arm 26 as well as the electric motor 14, the servo motor 13 and the lower tool part 10 is fixed to the machine frame 25. ·· * · • · * «· # ·· • •« • * t • • • • * * Φ
