Definitions
- the invention relates to a press drive for a press.
- the press drive has a toggle mechanism.
- the toggle mechanism is driven by an eccentric, which can also be referred to as a crank drive.
- the toggle mechanism couples the eccentric drive with a plunger of the press, so that the drive movement of the Exzen ⁇ ters the eccentric drive causes a linear movement of the plunger in the stroke direction.
- Presses with toggle mechanisms are generally known. From DE 10 2005 001 878 B3 a press drive with knee lever mechanism ⁇ indicate where the ram of the press is to ⁇ set of drive assigned a. This additional drive is used in ⁇ particular to ensure a sufficient ram force in certain kink angle ranges of the lever of the toggle mechanism.
- the other arm of this two-armed lever is coupled to the knee joint.
- the articulation points of the auxiliary connecting rod on the two-armed lever and a drive ⁇ rod between the two-armed lever and the knee joint are adjustable. By this measure, it should be possible to adjust the impact speed of the plunger on the work ⁇ piece, the travel of the ram stroke, the stroke length and the position of the lower reversal point of the plunger.
- Another press with toggle drive describes DE 198 46 951 AI.
- the first lever of the toggle mechanism is mounted on the press frame, while the other lever is connected to the plunger.
- the connection between these two levers via a wishbone, so that the first lever and the second lever are mounted on the wishbone spaced from each other.
- the wishbone is also connected via a connecting rod with an eccentric drive.
- the length of the connecting rod is changeable. If the toggle mechanism oscillates through its extended position, the plunger is moved twice in rapid succession through a lower reversal point due to the kinematics of the arrangement. The location of these two lower reversal points is different from a reference point on the press frame in the stroke direction. If the toggle mechanism does not oscillate through its extended position, an ordinary, approximately sinusoidal ram position course is achieved.
- a disadvantage of this arrangement is the under defenceli ⁇ che position of the two lower reversal points when the Kniehe ⁇ belgetriebe is moved through its extended position.
- a changing connecting rod length is undesirable in many cases. The length change alters the BEWE ⁇ supply of running connected to the knee joint end of the connecting rod.
- a device for length change of the connecting rod in particular if it is to take place by an actuator, structurally complex and increases the be ⁇ wegte mass of the connecting rod considerably.
- the press drive has a Kniehe ⁇ belgetriebe, which comprises a first lever and a second lever, which are pivotally mounted to one another at a knee joint.
- the toggle mechanism has a first bearing which serves for the pivotable mounting of the first lever on the press frame.
- a second bearing is seen ⁇ before, which serves for the pivotable mounting of the second lever on the plunger of the press.
- the first bearing is vorzugswei ⁇ se immovable or immovable relative to the press frame on the press frame. The position of the
- Pivot axis of the second bearing relative to the plunger is preferably also invariable before ⁇ .
- the toggle mechanism also has a connecting rod, one end of which is pivotally mounted on the knee joint.
- the knee joint has a common pivot ⁇ axis, about which the first lever, the second lever and the connecting rod are pivotally mounted to each other.
- the other end of the connecting rod is connected to an eccentric of an eccentric drive.
- one of the two levers or the connecting rod can also be designed as a triangular link with three articulation points each. In the region of the knee joint then two spaced-apart articulation points are present. One of the two levers and the connecting rod or the two levers engage at one articulation point, while the remaining lever or the connecting rod engage at the other articulation point.
- the pivot axes of the two spaced pivot points in particular run parallel to each other.
- a control device serves to control the eccentric drive. It is adapted to drive the Exzenteran ⁇ operating in a first mode or a second mode of operation. In another embodiment, a third mode of operation, or other operation modes ⁇ may be present.
- the choice of the suitable operating mode can be automated by the control device based on detected or predetermined parameters. Serving as a parameter, in particular the operation descriptive parameters such as the required pressing force of the plunger and / or the tappet stroke and / or the insbesonde ⁇ re depending on the position to be observed ram speed and / or transfer times for the insertion or removal of a workpiece into and out of the press ,
- the eccentric drive is driven to oscillate in a predetermined angular range.
- the eccentric does not rotate about the axis of rotation of the eccentric drive, but moves in a respective predetermined angular range oscillating between two angles of rotation limiting the angle range back and forth.
- the two angular ranges of respective operating mode selected so that the knee joint is moved through an axis connecting the first bearing and the second bearing axis. If the knee joint is on this axis, the plunger reaches its lower reversal point.
- the plunger would be twice its lower reversal point Errei ⁇ chen, namely preferably once in the first angular range of the first operating mode and once in the ⁇ Winkelbe second area of the second operation mode. Since the connecting rod opposite the levers in the first operating mode to another position a ⁇ takes, as in the second mode of operation when the plunger is in its lower reversal point, resulting in the various operating modes, different force and Be ⁇ wegungsteil. In particular differed ⁇ Liche maximum achievable pressing forces and differing ⁇ che ram speeds for the same Exzenterfan Anlagen result.
- Adjustment means for adjusting the eccentricity, the axis of rotation of the eccentric, the connecting rod length or the position of the first or second bearing can be omitted.
- the press drive therefore requires only a small number of components. He is very simple and robust.
- the minimum number of bearings and the elimination of additional adjustment means reduces play in the press drive to a minimum so that the plunger can be accurately positioned repeatably.
- the press force and / or the plunger position can be controlled or regulated. In the case of a control corresponding position sensors and / or force sensors are provided.
- the eccentric In the third operating mode - if provided - the eccentric is rotationally driven about an axis of rotation of the eccentric drive.
- the eccentric circles it the axis of rotation completely in one direction of rotation and oszil ⁇ liert not.
- This third operation mode is suitable for playing for a ⁇ forming task, wherein the provided in the second operating mode, pressing force sufficient.
- ⁇ counter to the second mode of operation advantage may erge ⁇ ben, as when a large stroke is necessary or appropriate for a high output.
- the kinematic conditions by the connecting rod and the two levers in a full ⁇ permanent circulation of the eccentric about the axis of rotation during the downward movement and the upward movement of the plunger are different.
- This difference can be compensated for or at least reduced, in which the engine speed of the eccentric and thus the rotational speed of Ex ⁇ zenters is changed to the axis of rotation during a revolution.
- the same plunger movement can be achieved, regardless of the angular range in which moves the eccentric.
- a pendulum operation is performed.
- the eccentric is driven to oscillate in a pre give ⁇ NEN angle range.
- the eccentric oscillates in the angular range between two angles of rotation limiting the angular range.
- the angular range of the fourth mode of operation is that the knee joint by the first bearing and the second bearing connecting axis is not moved through (yield ⁇ position) is chosen.
- the region in which the plunger moves in the stroke direction therefore does not include the lower reversal point which can be achieved in the extended position of the knee joint.
- the plunger can, for example, oscillate in a section of the sinusoidal movement curve in which a large stroke movement of the plunger is achieved at low rotational movements of the eccentric.
- This idea can also be realized in other transmissions than the toggle mechanism described above, for example in eccentric gears, in which the eccentrically mounted and driven connecting rod is connected directly to the plunger.
- the first angular range of the first operating mode and the second angle range of the second Be ⁇ operating mode in no overlap area.
- the Drehstel ⁇ ment of the eccentric is always different in the first angular range of the rotational position of the eccentric in the second angular range.
- the two operating modes are completely different from each other.
- the longitudinal axis of the connecting rod As the longitudinal axis of the connecting rod, the axis is to be understood by the knee joint and the pivot point of the connecting rod on the eccentric. If the plunger is in the lower turning point in the first operating mode, the longitudinal axis of the connecting rod with the axis connecting the first and the second bearing encloses a first angle. Accordingly, the longitudinal ⁇ axis of the connecting rod with this axis includes a second angle when the plunger is in the second operating mode in its lower reversal point. The amounts of these two angles are different sizes.
- the Be ⁇ supporting the first angle is greater than the second angle.
- the magnitude of the first angle is at least a factor of 1.3 to 1.5 greater than the magnitude of the second angle. Thereby, the Un ⁇ equality of conditions in both modes of operation is particular ⁇ DERS pronounced.
- the amount of the plunger speed in the lower reversal point at the same rotational speed of the eccentric in the first operating mode is smaller than in the second operating mode.
- the amount of the maximum pressing force in the first operating mode can be greater than the amount of the maximum pressing force in the second operating mode.
- the control device can be dependent of parameters automatically select the appropriate operating mode. The parameters can be predetermined by an operator via an operating unit or can be detected in a test operation by the control device.
- the first mode of operation automatically by the control unit provided a ⁇ when a maximum force of the press is required.
- the maximum attainable force of the plunger is in the first operating mode Be ⁇ RESIZE ⁇ SSER than in the second operating mode.
- the determined by the arrangement of the connecting rod and the two levers kinematics of the press drive can be chosen so that the two Hü ⁇ be during a complete revolution of the eccentric about the axis of rotation at least almost the same size. It is also possible by changing the kinematics of the press drive to increase the stroke difference between the two strokes in a complete eccentric circulation. This difference in terms of the pressing force and the Stêtelge ⁇ speed can be increased in the first and second angular range. For example, the maximum pressing force in the first angular range can be increased relative to the second angular range and the ram speed in the second angle range can be increased with respect to the first angular range at the same eccentric rotational speed.
- the control unit can automatically set the second operating mode when the required pressing force is achievable in the second operating mode. This increases the output of the press.
- the required pressing force can be entered via the operating unit by an operator or sensed during a test operation by performing at least one test stroke of the ram. As already mentioned, other parameters can also be detected during the test operation by the control unit, such as for example the transfer duration of the workpieces.
- the press drive can also be operated in more than the previously explained three operating modes. For example, it is possible to select one of four maximum achievable pressing forces depending on the forming task.
- the pressing forces can be different in the first and second angular range in addition depending on from which direction, that is in which the direction of rotation of the eccentric to the Exzentercardachse, the plunger To ⁇ break point reaches the bottom.

- the eccentricity e is chosen such that the eccentric 35 in the stroke direction H can be seen depending on its angle of rotation CC about the axis of rotation D above or below the first bearing 28.
- the plunger 15 In the first region Sl, the plunger 15 reaches its lower reversal point UT at a second rotational angle CCl, and in the second region S2 the plunger 15 reaches its lower reversal point UT at a third rotational angle CC2.

Accordingly, the second operating mode B2 or third operating mode B3 is selected. It is also preferably considered whether the entire ram stroke is needed or not.
- the operator constraints are, for example, Stö ⁇ ßel Oberen and / or ram speed limits at certain points or sections of the plunger characteristic. If the press force requirement is higher, only the stronger but slower first operating mode Bl left, and the calculated output can only be accepted.
